Friday evening

“But before we continue,” Cassie said, “I want something to remember this day by.” She walked over to the pants she had discarded on the floor and pulled her phone from one of the pockets. After a few taps, she took a step back towards me. “Say cheese,” she said as she held the phone out in front of her. “What? Are you crazy? What if someone sees those?” Cassie rolled her eyes. “Yeah, because the first thing I’m going to do is upload these to Facebook. ‘Here’s a picture of me slaughtering my best friend. 500 people liked this.’ Come on Susan, give me a little credit. I don’t want to spend the rest of my life in a jail or laboratory any more than you do. The only place these photos are going is in the same password-protected folder on my computer where I keep my own nude pictures.”

“You have nude pictures of yourself?” I asked. She’d never mentioned anything to me about that. “Of course. And the only one who’s going to be seeing them is me. And possibly a certain hot young teenage girl I know, provided she asks nicely enough.” There was a definite glint in her eye. “If anyone else wants to see them,” she continued, “they’ll have to brute-force the password, which should take them… oh, about a decade or two, give or take a year. Don’t you ever take nude shots of yourself?” I blushed. “Well… yeah. Except I don’t keep them in a password-protected folder or anything.” Cassie looked at me. “I know I’m going to regret asking this, but where do you keep them?”

“Uhm… they’re in a folder called ‘Homework’…” Cassie facepalmed. “Oh lord. Susan, honey, you know I love you, but you really need to learn about digital security. We live in an age where any leaked photo will be seen by the entire school within a minute of someone getting their hands on it. Leaving your private stuff out in the open like this just isn’t safe anymore. That’s it, after this weekend we’re going to sit down and I’ll teach you the basics of what you need to know. And while we’re at it, we’re going to have a look at those pictures of yours, because now I’m all curious.” I grinned. “You show me yours and I’ll show you mine.” Cassie raised an eyebrow. “Oh yeah? And who’s going to stop me from walking over to your computer right now and looking at them? ‘Homework’, was it?” D’oh. “You’re really milking this whole ‘helpless’ thing for all it’s worth, aren’t you?”

“Naturally.” To prove her point, Cassie bent over and brushed her thumb lightly over my clit. “And you wouldn’t have it any other way. But I’ll agree to your deal, because I’m not going to waste my time looking at old pictures when I could be shooting new ones instead. Now how’s about that smile?” I gave her a radiant smile and heard the shutter noise. “Okay, can you raise your head?” I did so and Cassie lowered her phone to just above the bed, about a foot in front of my pussy. “Can you lift your head a little more? I want to get your pussy and head in the same shot, but I can’t see your mouth.” I tried to do so, but with no way to stabilize myself my head quickly fell back onto the pillow. “You know I’d love to, but it’s kind of hard without any leverage whatsoever.”

“This from the girl who can twist herself into positions in gym class that leave me sore just thinking about them? Come on, put some backbone into it. You’ve still got one of those, don’t you?” I strained to lift my head as far as possible. “Perfect. Now smile.” Click. Next, Cassie took some close-ups of my stumps, or lack thereof, one overhead shot with the camera pointed straight down above me and then sat down on the foot of the bed. “Hold on, I want to get one of your pussy gaping open.” She put down the camera and pulled my pussy lips apart, but they closed before she could pick up the camera again. Cassie gave it two more tries, but every time she was too slow. “Guess we’ll have to try this another way.” Holding her phone in one hand, she inserted three fingers of her other hand into my pussy, quickly followed by the other two. She made a fist and started pumping it backwards and forwards. I closed my eyes to enjoy the sensations, but before I could really get into it Cassie quickly withdrew her hand from my pussy and I heard the click of the shutter. “There we go, wonderful. Wanna see?” She turned the phone around to let me look at the photo. There was my pussy, in all its glory, gaping wide and slightly glistening with moisture. Of course I’d seen my own pussy plenty of times, but never in that state or from that angle. It was getting me hot just looking at it. “Are you going to give me a copy as well?”

“Sure, as soon as you learn to keep your ‘homework’,” Cassie said, using air quotes, “in a more secure location. Think of it as an incentive.” I rolled my eyes at her. “But now that we’ve gotten a good look at your outer beauty,” Cassie said, walking over to the duffel bag, “how about we start exploring your inner beauty?” I laughed. “Why do I get the feeling you’re not talking about my winning personality?” Having found what she was looking for, Cassie stood back up holding a scalpel, grinning devilishly. “Because you’ve got a brain? For the time being, that is.”

That Cassie, always the comedian. At least, I think it was a joke. Right? Don’t I kind of, you know, need my brain to live? Before I could worry about it more, Cassie jumped on the bed and positioned the tip of the scalpel in the center of my torso, a little below my breasts. She put some pressure onto the blade and it sank into my skin. Once she’d decided the scalpel had gone in deep enough, she started pulling it towards her, carving through the layers of skin and muscle like a hot knife through butter. She slowed down a little when she reached my belly button and sped up again once she cleared it. She stopped a couple of inches above my pussy.

There wasn’t much to see yet; because I was lying down my skin stayed as it was, except it now had a thin cut along my abdomen. Cassie positioned the blade at my left side at the same height as the start of the cut. She cut across to my right side, making sure to connect this horizontal cut with the top of the vertical one. She did the same thing at the lower end, though because my legs had been cut off so high up she had to angle the two horizontal segments, making it look more like an arrow than a T-shape. Cassie dug her fingers into the central cut and folded open the two flaps, revealing the contents of my abdominal cavity.

While I had often thought the ceiling mirror above my bed somewhat strange – not that I was complaining, mind you; I’d made good use of it in the past – I was really happy with it being there now, because it offered a much better view of things than I had looking down. I could see my liver, stomach, the large and small intestine and the bottom of my ribcage peeking out just below the top of the opening. “Oh yeah, this definitely calls for another picture,” Cassie said, picking up her phone again. “Smile.” I smiled as she took some overall shots, followed by some close-ups of my insides. “Now,” she said, “since your previous anatomy lesson made the CliffsNotes version look like War and Peace, I figured we were due for a remedial class so we can do it properly this time. Let’s get started, shall we?” She picked up the scalpel again.

“This is the liver,” she said, pointing the scalpel at it. “It’s actually one of the more versatile organs in the human body. It decomposes red blood cells, produces hormones, breaks down toxins and creates proteins, among other functions. But it has one property that no other organ has. Can you tell me what that is?” I tried thinking back to biology class in school, but drew a blank. “Uhm… I’m sorry teacher,” I said, slipping into my role as student, “but I don’t know.” Cassie smirked. “Haven’t done your homework again, Miss McKenzie?” She tried to sound annoyed, but couldn’t quite hide a little smirk. Apparently she enjoyed the teacher-student dynamic. “Very well then. The liver is the only organ that can regenerate itself. You can remove as much as three quarters of it and it will all grow back. Normally this takes quite a while, of course, but since we now both have some kind of super-healing ability I wonder whether that also affects the liver.” She cut a small piece off my liver and we both watched as it slowly but surely grew back.

“Excellent. That leads me to another thing about the liver: according to Hollywood, it’s supposed to taste pretty good with some fava beans and a nice Chianti. Fortunately, I just so happen to have both of those with me.” She stood up from the bed and after rummaging around in the duffel bag for a bit she returned holding a Tupperware container of round green beans, a bottle of red wine, two wine glasses, a corkscrew and a spoon. “Wow, you really went all out on the planning, didn’t you? No wonder that bag was so heavy.”

“What can I say? I’ve been looking forward to this.” Cassie sat back down, uncorked the wine bottle, poured two wine glasses, which she placed on the nightstand, and opened the Tupperware container. “Let’s see if this tastes as good as advertised.” She scooped up a spoonful of fava beans, placed the piece of liver she’d cut off on top and stuck the spoon in her mouth. I watched her face take on an appreciative expression as she chewed a couple of times before swallowing, chasing it down with a drink from her wine glass. “Hm, I’ve got to hand it to Hannibal, this tastes pretty good. Want some?” I shrugged, “I might as well, right? Hey, quick question: is it still considered cannibalism if it’s your own flesh you’re eating?” Cassie pondered this for a second. “Huh, good question. I never thought about it. I’d guess so.”

“Yeah, probably. ‘Susan the Cannibal’ doesn’t quite have the same ring to it, though. You at least have the alliteration thing going. Too bad my parents didn’t name me Annabel.” Cassie cut off another piece of my liver, put it on top of some beans and held the spoon in front of my mouth, lifting my head with her other hand. “Now open up for the choo-choo train,” she giggled. “Ha ha. I’m limbless, not two years old, you moron,” I said, shooting her a disapproving look. “Awww, but you’re so adorable like this,” she said in that voice people use when they talk to babies, “all helpless and needing me to feed you.” Sigh. The things I have to put up with. “Are you going to feed me or not?”

“Okay, okay, fine, you spoilsport.” I opened my mouth and tasted myself for the first time. Well, it was the first time tasting a solid piece of myself, anyway. I was quite familiar with the taste of my own pussy juice. Cassie was right, though: this didn’t taste half bad. After swallowing, she held my wine glass to my lips, tilting it so I could take a sip. The fruitiness of the wine, which tasted a bit like cherries, complemented the rest well. Cassie had already cut off another piece for her second bite. Since it was pretty much dinner time anyway, we decided to skip the pizzas my mom had laid out for us and instead continued to dine on my liver.

---

“Phew, I’m stuffed,” I said. “I’ve been at an all-you-can-eat buffet before, but this is the first time I’ve actually been an all-you-can-eat buffet”. Cassie put down the spoon. “Yeah, I couldn’t eat another bite either,” she agreed. “Guess we’ll have to leave the rest for leftovers”. Using the scalpel, she severed the connections to my other organs and lifted out the liver, dropped it in the now empty Tupperware container and replaced the lid. “Now that we’ve eaten, let’s continue with our lesson, shall we? This,” Cassie said, grabbing hold of the small organ that had been hiding under my liver, “is the gallbladder. It helps break down fat in foods, but isn’t actually all that important. Hundreds of thousands of people have it removed each year without any issues.” She gave a quick tug, tearing the organ free and tossed it over her shoulder like a piece of trash.

“The gallbladder releases bile into the small intestine, which start here, a little below the stomach.” She sliced through my digestive tract at the point she indicated and started pulling out my small intestine. “The small intestine is where most of your food is digested. It’s pretty long; about 23 feet in adults.” By now she’d removed most of it: it ran from the one end, where it was still attached to me, straight to the edge of the bed, most of it lying coiled on the floor.

“The small intestine ends where it connects to the large intestine.” She held up the part where my bowels got noticeably thicker and made another cut, severing the small intestine completely. “Aside from digesting food, the small intestine also has another interesting function, though you won’t find it in any textbook.” She measured out about seven feet of it and made another cut. She stood up, holding one end of the segment she’d cut off in either hand. “It makes for an excellent jump rope.”

She started jumping up and down, swinging the impromptu jump rope around her. “Wow, I haven’t done this in years!” After a few dozen jumps she stopped and dropped the ‘jump rope’ on the floor. “Okay, that’s enough exercise for one day. Where were we? Oh right, the large intestine. The large intestine absorbs water out of anything that wasn’t digested and turns it into waste, or ‘shit’, as you young people call it.” I raised my eyebrow. “I’m three months older than you,” I said. “Quiet, Miss McKenzie, or I’ll have you sent to detention.” I sighed theatrically. “Sorry, Miss Sullivan.”

“Good. Here, at the start of the large intestine, you’ll notice another largely useless organ; the appendix. There is a theory that it serves as a safe haven for useful bacteria, but it hasn’t been conclusively proven yet. Again, plenty of people have it removed with no ill effects.” Once again, she tore off the organ and carelessly tossed it behind her. “If we follow the large intestine, we arrive at the rectum, which stores the waste until you’re ready to defecate, which happens by relaxing the muscles around your anus.” I opened my mouth, but Cassie spoke before I could.

“Yes, one of the planets in our solar system has a funny name. Also, that joke stopped being funny decades ago.” I closed my mouth again. I suppose it was a little too obvious. Cassie made another cut just above my asshole and dropped the large intestine beside the bed. My asshole was now nothing more than a hole in my skin. I relaxed it a little and could see the bed appearing through it. With the largest organs removed, my abdominal cavity was a whole lot emptier: I could see my spine already.

Cassie continued her lesson, pointing at the organ below my stomach. “This is the pancreas. It has two main functions: to release enzymes that help digest food, and to release hormones such as insulin, which helps prevent diabetes.” Another rip and I’d lost another organ. She rummaged around underneath my stomach for a bit, emerging holding a small organ. “Here we have another entry in the category of optional organs. The spleen regulates red blood cells and the immune system. Like the gallbladder and the appendix, it can be safely removed in normal people. That probably goes double for us since we don’t seem to have any blood whatsoever.” She yanked it free and discarded it.

“Okay, enough with all these boring useless organs. Let’s get back to something more interesting.” She grabbed my stomach and drew it down a bit, stretching my esophagus so she could cut it off at the top. “Let’s see what you’ve had for breakfast. One sec, though; I don’t want to get acid all over everything.” Cassie walked over to the duffel bag to grab a large glass oven dish and a pair of surgical gloves. She placed the oven dish on the bed and lifted my stomach into it. After snapping on the gloves, she sliced it open and carefully upended it, pouring the contents into the oven dish. She managed to do so without splashing.

“Let’s see, what have we here? These are clearly the liver and fava beans we just had, I’m assuming the orange-red liquid is a mix of the wine and the orange juice you drank earlier, but I don’t think I can recognize the other stuff.” She sifted through the contents with her fingers. “Any idea what this might be?” I mentally went through what I’d eaten for the last few meals. “I think that’s chicken. And that piece a little to the left of it –”

“This one?” Cassie pointed her finger at it. “No, further left – yeah, that one – I’m pretty sure that’s broccoli. That’s what I had for lunch, at least. And that would probably make those little bits – right, those – the cereal I had for breakfast.” Cassie nodded. “Cool. Uhm, I mean… very good, Miss McKenzie. Anyway, as you can see, the stomach is where food is dissolved in acid to break it down into pieces that are small enough to digest. Aside from the esophagus, which I can’t get to at the moment, this concludes our tour of your digestive tract.”

She peeled off the gloves so they were inside out and dropped them on the floor. “Next up is the urinary tract, which starts at your kidneys. They filter waste out of the bloodstream, converting it into urine. They also maintain salt and water balance. As you can see, they are connected to your bladder by means of the ureter. In normal humans there would also be two veins coming out of them to connect them to the circulatory system, but as we’ve already established, we’re not exactly normal.” I chuckled. “Yeah, somehow I don’t think any of our classmates are spending their evening dissecting each other.”

“Their loss. This is the most fun I’ve had in months. Now, in order to prevent leaking urine everywhere I’m going to have to tie the ureters off first.” She made a large loop in one of them, pulled the kidney through to complete the knot, pulled the knot tight and then cut through the ureter between the knot and the kidney. She tossed the kidney aside and repeated the process for the other one. “Okay, so far so good. Anyway, urine from the kidneys is sent to the bladder, where it is stored until you go to the bathroom, at which point you relax the muscles around your urethra, which is this tube here, which leads to the outside. Unfortunately, the urethra is a bit too short to tie a loop into, so I’m just going to try to hold it closed until I can dump the contents.” Cassie clamped my urethra between her thumb and forefinger a little above the end and cut it off between the skin and her fingers. With her other hand, she lifted my bladder out of me until it was hanging over the oven dish, at which point she released her two fingers, causing quite a bit of pee to splash into the contents of my stomach. Once the stream had stopped, she gave the bladder a few good squeezes to get the last few drops out. “There we go, didn’t spill a drop. Plus, I saved you a trip to the bathroom.” I rolled my eyes. “Yeah, thanks, this is much more convenient than just going to the bathroom.”

“Oh, hush you. Let’s see, it looks like all we have left is your reproductive system. Finally we’re getting to my favorite bits.” She grabbed her phone and took another overview shot, one with my all my internal and external sexual organs, followed by some close-ups of my womb and my ovaries. Replacing the phone with the scalpel, she resumed the lecture. “On the outside of the pussy we have the pussy lips, or labia. There are actually two sets: the labia majora, which look like normal skin, and the labia minora. The labia minora vary in size from woman to woman. For some they are almost completely hidden in the labia majora, like mine –” she spread her legs and pointed at her own pussy “– other women, like you, have larger ones that are visible all the time.”

She grabbed one of my pussy lips and stretched it away from my pussy. “The labia minora are pretty stretchy: depending on the girl they can stretch out several inches.” She pulled a bit harder and stopped when she reached about two inches. “I think this is as far as they go.” Still keeping it stretched, she placed the scalpel at the top, just beside my clit, and slowly started cutting down. When the last bit of flesh had been cut, it came away entirely, shriveling back up to its original size. She put it down on the bed and cut off the other one in the same manner. “At the top of the pussy, where the two labia minora meet, is the clitoris. It is a very sensitive bundle of nerves that, as you’re no doubt well aware, produces a pleasurable sensation when touched, like so.” She briefly touched my clit with the tip of her forefinger, sending a jolt of pleasure through me. “What you might not know is that the clitoris is not just the tip that most people know about. It actually curves downward, splits in two and continues for several more inches. We can get a better look at the start of it by cutting away the clitoral hood.”

She positioned the scalpel upside-down, the tip at the edge of my hood, barely touching my clit with the blunt side, but enough to start building an orgasm. “Hey, lie still, will you? This is tricky enough without you moving about,” she said. “Sorry, couldn’t help myself.” I tried thinking of math to distract myself from the feelings that the metal blade gave me. Cassie carefully started cutting upwards, parting my hood. When she reached the end, the made a small lateral cut, giving my clitoral hood two flaps, which she held open with her fingers. “If you thought touching the end felt good, try this.” She lowered her head to my pussy, lifted the exposed inch and a half of my clit up with her tongue and sucked it into her mouth, massaging it with her lips and teasing the end with her tongue.

Holy shit! My entire nervous system was on fire. I’d never felt anything so good before. I managed to hold on for about ten seconds before fireworks exploded behind my eyes and I came explosively. I was still panting with my eyes closed when I felt her sit back down on the bed. Apparently I’d missed her standing up. “Did you enjoy that?” Cassie asked. “Are you kidding? If you promise to do that more often, you can cut me up any time you want. Hell, I insist on it.”

“Glad to hear it. But for now, let’s continue with our lesson.” She grabbed my clit with a pair of tweezers that she must have gotten from her bag and started pulling. Slowly but surely, she pulled my clitoris out of me a fraction of an inch at a time. While not nearly as pleasurable as her mouth, the pressure from the tweezers was working its magic. “Look, you can see the part where it splits in two.” With less and less of my clitoris remaining in my body, Cassie was starting to gain speed. I closed my eyes. Just a little more stimulation…

Suddenly all feeling from my clit disappeared. I opened my eyes and saw my entire clitoris hanging from the tweezers, making an inverted Y-shape. “Gaaaah! How do you always manage to stop just short of giving me an orgasm?” I yelled. “Because I wanted to demonstrate something, Miss McKenzie. So if you’d kindly stop interrupting me…” Lacking the fingers to “zip my lips,” I snapped my mouth shut demonstratively. “That’s better. As I was about to say, now that we’ve removed the external genitalia, it’s time to start looking at the internal ones. First is the vagina, which is the tube leading to the uterus. This is where the male penis is inserted for fertilization. At the top of the vagina is what’s known as the g-spot, which is another erogenous zone like the clitoris.” She inserted two fingers into my pussy and started making a “come here” motion, curving her fingers upwards. “Ooh, there it is. Don’t stop,” I moaned when she hit the right spot. The feeling wasn’t as strong as the one from my clitoris in its normal state, let alone when it was exposed, but I wasn’t about to complain. Hell, in a minute or two I wouldn’t have any sexual organs anymore whatsoever, so I had better enjoy this while it lasted. Pretty soon she had me writhing as another orgasm washed over me. It took a minute for me to regain my senses. There were definite advantages to having a friend with extensive anatomy knowledge. “Do I have your full attention again, Miss McKenzie?” I nodded. “Sure thing, teacher.”

“Very well. Once the male ejaculates, the sperm travels upwards, through the cervix and into the uterus where, if the timing is right, there’s an egg waiting to be fertilized. The egg comes from the ovaries: once a month, an egg is released and travels through the fallopian tube into the uterus, where it nestles into the uterine lining.” She indicated the path with her finger. If the egg has not been fertilized, it is expelled from the body, along with a lot of blood, which is known as having your period.” I rolled my eyes. “Tell me about it. I don’t know who designed the human body, but they did a pretty shitty job on that one. I was mortified when I had my first period.”

“Yeah, me too. Good thing my mom had explained it beforehand or I would have thought I was dying. There is one way of getting around it, though.” That piqued my curiosity. “Really? What is it?” Cassie pinched one of my fallopian tubes between her thumb and forefinger, just above the uterus, and pulled, severing it completely before tearing it free from the surrounding tissue. She ripped out the other one as well. “Simple: no eggs, no period. In fact, just to be sure, let’s perform a hysterectomy as well.”

“A hyste-what now?” She cut through my vagina just below the mouth of my womb. “Hysterectomy: the removal of the uterus.” She held it in front of my face so I could get a better view. “If you look at the bottom end, you can see your cervix.” I looked at the puffy, circular piece of flesh with a small hole in the middle. “It’s hard to imagine that not an hour ago you could fit your whole hand through that tiny hole,” I said.

“Yeah, the female reproductive system is amazingly flexible. Of course, it has to be, since it’s designed to transport an entire baby.” She placed the uterus on the bed with the rest of my genitalia and cut off the tube of my vagina as well, leaving my abdominal cavity entirely empty save for my spine and pelvis. No more orgasms for poor Susan. Cassie took this occasion to take some more pictures. “Hey, Susan. Do you know how they sometimes call a man’s junk his ‘crown jewels’?” she asked. “Yeah, why?”

“I never really understood that; none of it looks like any jewelry I know. I mean, what do they have? A rod and two balls? I’ve never worn anything like that. The female genitalia, on the other hand, are much more suited as jewelry. For example –” she picked up one of my pussy lips, tied it into a loose knot and put it around her left ring finger, pulling the ends tight with her other hand. She tied the other around her right ring finger. “You’ve got rings…” She took out her earrings and threaded my fallopian tubes through her earholes after tying a small knot at their ends. “Earrings…” Cassie cut my vagina into two pieces of equal length and inserted her hands through them. “Armbands…” She took my womb and cut just behind the cervix to separate it. Then, placing the scalpel at a slight angle to the opening, she started cutting in a spiral pattern, like trying to peel an apple all in one go. Soon, my uterus was one long strip. She inserted one end into my cervix and moved it down the strip until it was in the middle. She positioned the resulting necklace so that the ‘pendant’, i.e. my cervix, was hanging at the right height, then looped the rest around her neck several times, tying the ends behind her neck when she reached the end. “And a necklace. All the jewelry a lady needs.”

“Heh, I must say I look pretty good on you. I can’t help but notice you haven’t used my clit yet, though,” I said. “Hey, I never said I was a lady, now did I?” She cut off the two ends of my clit and started rubbing her nipples until they were jutting straight out. This didn’t take very long, since they were pretty hard already. She placed the tip of the scalpel against the side of one of them and pierced it through to the other side. She inserted one of the ends of my clit into the hole and tied a knot. She did the same to her other breast. She moaned as she pulled on them. “Wow, I think I might get some real nipple rings ones after this. This feels great. And now for the final piece: a clit piercing.”

She started fingering her clit and pulled back the hood. She sucked in her breath and pierced the scalpel through her clit. She screamed as she clearly had a powerful orgasm. When she had calmed down, she picked up the remaining part of my clitoris and threaded it through hers. “Oh yeah, I’m definitely getting one of these.” She fingered her now pierced clit and shuddered as she had another orgasm, albeit smaller than the previous one. She stood up to admire her new jewelry in the mirror. She also took some pictures of herself in her new accessories. “You know, now that I have all this beautiful new jewelry, I think I need a new outfit as well,” she said, tapping her finger to her lips. “Well, my wardrobe is over there. Help yourself,” I said. “Thanks, but that’s not quite what I had in mind. How about a little pop quiz, Miss McKenzie, to see if you’ve been paying attention. What is the largest organ in the human body?” I thought back to all the things that had come out of me this evening, and what little I had left.

“The lungs?”

“Wrong.”

“The small intestine?”

“Nope.” Huh? Those were definitely the two largest ones; all the others were smaller. “I give up.”

“It’s the skin. In fact, it makes up about a sixth of your body weight.”

“Really? The skin’s considered an organ? Okay, if you say so.”

“Yep. And if you hadn’t guessed already, this ties in rather nicely with where I’m going to get my new outfit from.”

“Yeah, I figured as much. Okay, let’s get going then. You’re already wearing half my body in one way or another; might as well complete the ensemble with a Susan-leather jacket,” I said dryly.

“Gladly.” Cassie closed the two flaps of my abdomen and traced her finger over the cuts, which disappeared without a trace. Starting at my right shoulder, about an inch or two left of my arm stump, she started cutting a semicircle down to the top of my breasts and back up to the other shoulder. This would probably mark the neckline. She lifted me upright and made the same cut on my back. Next, she made a cut all around the base of my neck, and two cuts across my shoulders connecting the sides of the smaller circle with the larger one.

Starting at one of the cuts across my shoulders, she started skinning me by cutting away the top layer of skin, peeling it away as she worked, leaving the underlying muscles untouched. Soon she’d removed both pieces of skin, leaving me with a very red cleavage. Starting at the back of what was going to be one of the shoulder straps, Cassie inserted the blade under my skin and started cutting up, over my shoulder and back down until she’d freed the whole thing from the underlying layers. Once she’d done so, she pulled the strap to the side, off of my shoulder, which introduced some slack that allowed her to lift up the ends of the strap and start cutting from there. She did the same thing on the other side and then it was just a matter of waiting while Cassie more or less peeled me like a banana, turning the part she’d cut off inside out so she could access the rest. It took quite a while: the scalpel’s small size allowed her to work very accurately, but it was a lot to cut through for such a small blade.

Still, Cassie persevered, and after a good ten or fifteen minutes she severed the last link between my skin and my pussy, leaving me completely skinned, save for my head. While Cassie was stepping into the leg holes of what looked like a one-piece swimsuit made of skin, I admired myself in the ceiling mirror. My entire torso was now a bright red, save for my breasts, which were yellow. “Hey, teacher?” Cassie stopped. She’d just gotten her left arm through the corresponding arm hole. The other side was still bunched around her waist, which left one breast exposed.

“Yes, Miss McKenzie?”

“Why are my boobs a different color than the rest of me?”

“Ah, that’s simple. Your breasts are comprised mostly of fat tissue, which is yellow, whereas the rest of what you’re seeing is muscles, which are red.”

“Huh. So boobs are basically just bags of fat?”

“Indeed.”

“Weird.”

“How so?”

“Well, it just seems a little strange that women go to great lengths to avoid fat in the rest of our body, but when it comes to boobs it’s usually the bigger, the better.”

“One of the mysteries of the universe, I’m afraid.”

She did up the other side as well and looked at herself in the mirror, turning around a couple of times. “Hm,” she hummed. “What is it? Doesn’t it fit?” I asked, and laughed. “I’m afraid I don’t have any other sizes of this particular item in stock.” Cassie shook her head. “No, it fits fine, It’s just that I don’t think a swimsuit is quite what I had in mind. For one thing –” she spread her legs a little, which showed her own pussy visible through the hole that had once been the entrance to mine “– who ever heard of a crotchless swimsuit?”

“Can’t say I have,” I replied. “I’m afraid I don’t have much ‘fabric’ left to make alterations, though.” Cassie considered this for a moment. “Don’t worry, I think I can work something out.” She grabbed the scalpel again and started cutting a little above the leg hole. She cut all the way across her belly to the other side and then back to the starting point via her back, making sure not to slice deep enough to cut into her own skin. She made the same cut about an inch below her breasts, dividing the garment into three pieces. She pulled the middle one down over her hips, until it formed a miniskirt. “There, much better. Halter top, miniskirt and crotchless panties. A much more sensible outfit.”

“Agreed, you look pretty sexy. In fact, I’m getting all kinds of ideas of things I want to do to you. Unfortunately, I’m a little indisposed at the moment.”

“Is that so? Well, there is one thing you can do for me.”

“Really? I don’t see how, but okay, what is it?”

“Well, I’ve got some nice new jewelry and a new outfit; what’s missing?”

“Uhm, I don’t know? A facial? Nail polish?”

“Those are not bad ideas, but I was thinking of a new hairstyle. In fact, I rather like yours.”

“Well, there’s a comb in the bathroom, as well as a can of hair spray.” Cassie started walking over to me, scalpel still in hand and with an evil grin on her face. “I think you misunderstand. I said I liked your hairstyle. Besides, I’ve always wanted to be a redhead.”

“Ah. Hey, just a thought: wouldn’t it be easier to just put your brain in my body, rather than just taking it over piece by piece? It seems like a much more efficient solution.”

“Perhaps, but then you wouldn’t learn anything about anatomy, would you? For example, what would you have answered not fifteen minutes ago if I asked you what the color of the inside of your breasts was?” I sighed. “Red.” Cassie nodded. “Exactly. And would you have known where your g-spot was?” she asked. “No, Miss Sullivan.” And from now on, I was certainly going to put that little tidbit of information to good use. “Okay, I see your point, carry on,” I conceded. “Thanks.” She smiled, adding: “Not that I actually need your permission, of course.” She wasn’t going to let me forget that, was she? Slicing into my forehead just below the hairline, she traced it down to my temples, over my ears, down to the top of my neck and back around to where she’d started.

Once the cut had been completed, she lifted my entire scalp off of me, revealing the top of my skull. Cassie walked over towards the mirror and started cutting off her own scalp in the same way. The front and sides were easy enough, but the back she had to do by touch. She managed, though, and she let her own hair fall to ground and replaced it with mine. The cut healed as usual, removing all evidence that the brown wig pooled around her feet was her actual hair, rather than the red locks she was now sporting. With her “make-over” complete, she took some more of pictures of herself before returning to me. “Alright, let’s continue with the lesson, shall we?” she asked. “Huh? Haven’t you pretty much emptied me out already?”

“Hardly. For one thing, in your lecture you skipped the head entirely. I intend to correct that oversight.” She picked up the hacksaw she’d used to saw off my limbs and aligned it with the edge of my skin on my forehead and started sawing it back and forth. When she felt a drop in resistance, she repositioned the saw more to the side and resumed sawing. She’d almost sawed through the front half when everything suddenly went black. “Hey, who turned out the lights?” I asked. “Oops, sorry. Guess I must’ve nicked your temporal lobe. Don’t worry, I’ll fix you once I get this skull out of the way.” I felt Cassie flip me around so she could start working on the back half. With my vision blinded, the only thing to focus on were the sounds of the hacksaw making its way through my skull. Being blind was pretty boring. Fortunately, I didn’t have too long to wait until Cassie completed the cut and the top of my skull fell away.

She flipped me around again and I felt her fingers move over my brain along the edge of cut, which was a pretty strange sensation. When she reached the right side of my brain, the world suddenly popped back into view in all its Technicolor glory. “Thanks, that’s better,” I said. “Good. Wouldn’t want you to miss my lesson on account of some silly excuse like being blinded, now would we?” she asked. “Yeah, that would be terrible.” Choosing to ignore the sarcasm in my voice, Cassie continued with her lecture.

“This, Miss McKenzie, is the brain. It is probably the most important organ in the human body, as it controls almost everything: muscles, senses, memories, thought, etc. Controlling the body is done by sending electrical pulses through the nerves down to the part you’re trying to move, such as your arm. The brain is one of the last great mysteries of the human body: scientists have a vague idea of how everything works, but there is still much we don’t understand. Einstein had a theory that we only use ten percent of our brains, but that has since been disproven. Personally, I think he was on to something though, so I wanted to take this opportunity to test my own theory.”

“Which is?” I asked. “That, especially in the state you’re in right now, you only need ten percent of your brain.” Gulp. Cassie picked up the chef’s knife and lined it up with the fold between the halves of my brain. “Don’t worry, there are plenty of real-world cases where a part of someone’s brain is removed, and they go on to live happily ever after, even without our special healing powers. For example, one such procedure is called a hemispherectomy, in which one of the two halves of a patient’s brain is removed. It’s occasionally performed on people with severe epilepsy.” Cassie started sliding the knife into my brain. “It has a tendency to cause paralysis in the limbs on the opposite side of the body of the half that is removed, but somehow I don’t think that will be a problem in this case.” There was a sound of metal scraping on bone as Cassie guided the tip of the knife all along the walls and floor of my brain cavity to fully sever the two halves. “Okay, time to remove one of them. Do you have a preference for which one you want to keep?”

“I dunno. I guess I’ve always been more creative than logical, so I’d like to keep the right half,” I said. “Very well.” She replaced the knife with the scalpel, and inserted it between my brain and the front of my skull. Suddenly the left quarter or so of my vision went dark as she severed the optic nerve.

She worked the fingers of her other hand in between the two halves of my brain, hooked her fingers under the left one and started lifting it out. Once she’d gotten it most of the way out, she cut the connection between the brain and the spinal cord, freeing it completely. She held it in front of me so I could see. “This wrinkled part on the outside is called the cerebral cortex;” she said, “it controls all kinds of stuff like memory, language and thought. This smooth bit below it is the corpus callosum, which is the part through which the two halves of the brain communicate. This part here in the back that looks like a tree is the cerebellum, and it handles motor control. And this straight bit is the brain stem, which connects to your spine.”

“Cool,” I said, “but there’s something I don’t understand. Without the left half of my brain, shouldn’t I be more or less incapable of logic? Somehow I can still hear you and reply and I can even still do sums in my head.”

“Yes, I was getting to that. That whole thing about the two brain halves having different functions isn’t actually true. But I figured it was easier to show you than tell you.” She placed the brain on the nightstand and returned her attention to me. “Fifty percent done, forty to go,” she said. “The next procedure we will perform is a frontal lobotomy. They used to do this to people in insane asylums to calm them down.”

“Well, most people would call what we’re doing here pretty crazy.” Cassie chuckled. “Indeed.” Using the scalpel, she started cutting off the front half of what she’d just told me was my cerebral cortex. Soon, it too was lying on the nightstand. “Those are the only two common operations in which part of the brain is removed,” Cassie said. “That doesn’t mean we can’t come up with some of our own, though. For example, the parietal lobe handles spatial navigation. And you’re not going anywhere.” She cut away another third of the remainder of my cerebral cortex and put it with the others. “And since there’s no other half of your brain to communicate with anymore, we can safely remove the corpus callosum. Similarly, since with no limbs you don’t need any motor control, the cerebellum can be taken out as well.” Two more pieces joined the growing pile of brain matter on the nightstand. “Unfortunately, that’s about as far as I can go without taking away anything important. All the rest is associated with stuff like vision, memory and language, which you still need. Still, I’d say this is a pretty good result.

It’s not quite the ten percent I was hoping for, but I think we definitely got it down to twenty. Now to check if I didn’t take out anything important. Can you still see and hear?”

“Yep.”

“And apparently you can still speak as well. What’s your name?”

“Susan McKenzie.”

“Okay, now for short-term memory: what did we have for dinner?”

“Me.”

“Be more specific.”

“My liver. We also had wine and fava beans.”

“Good. And long-term memory: when did we first meet?”

“In second grade.”

“Excellent. Well, I think that proves my theory.”

“Heh, good luck publishing it anywhere. I’d love to see you explain your experiment.”

“Yeah, I doubt I’ll be appearing in ‘Science’ or ‘Nature’ any time soon,” Cassie said. “For some silly reason they tend to frown on experimenting on people. Still, it was nice to satisfy my own curiosity. Let’s continue. This eye is now useless, obviously.” She lifted up the top eyelid of my left eye, inserted the back of the scalpel between the eyelid and my eye and popped it out of its socket, trailing a strand of optic nerves. Again, she held it in front of me so I could see it more clearly. “Wow,” I laughed, “I’ve never seen eye to eye with myself before.” Cassie smiled before continuing. “The black part in the middle is the pupil. It’s the ‘hole’ through which light enters your eye. It’s like the lens of a camera. Around it is the iris, which controls the size of the pupil. The color of the iris varies from person to person. Yours are a rather bright shade of green. Once it enters the pupil, the light falls on the back of the eye, where it is converted to electrical signals and sent to the brain via the optic nerve.” She tossed the eyeball away.

“Since I can’t cut out your other eye, we’ll move on to your ears.” She placed the scalpel against the top of my right ear and started cutting downwards. When she reached the bottom, it fell on the bed. The other one suffered the same fate before she dumped them on the floor. “Okay, I think it’s time to return to your torso.” I had to strain to hear Cassie now.

Apparently ears aren’t just decorative; they actually help focus sound into the ear hole. Who knew? Okay, probably the entire scientific community. And anyone with a basic understanding of physics. Hey, I was missing most of my brain, okay? Cut me some slack. Using the chef’s knife, Cassie cut through the base of my breasts, removing the last parts that proved I was a girl. Next, she inserted the tip of the scalpel in the base of my neck and started cutting downwards, along my sternum, across my abdominal cavity and down to the hole of what used to be my pussy. Opening the bottom was easy enough, but when she reached my ribcage she had to start using force, slowly tearing the muscles off the bone. After a minute or two she’d stripped the entire front of my torso. I could see my lungs expanding and contracting in my ribcage, as well as the beating of my heart. “The way I figure it,” Cassie said, “we don’t really need oxygen. After all, what transports oxygen? Blood. And what don’t we have?”

“Blood,” I replied. “Exactly. As we saw last time, I managed to survive just fine without lungs. It was only when you removed my heart that I ‘died’. A word of warning, though: It is going to feel like you’re suffocating. But just remember: everything will be fine. Don’t panic.” Okay. I could do this. Everything would be fine. Don’t panic. Everything would be fine. Don’t panic. She started cutting into the diaphragm. Everything would be – I couldn’t breathe. Try as I might, I couldn’t get any air into my lungs. I tried to hold on to the mantra. Everything would be fine. Don’t – I panicked. Had I still been in one piece, I would have run around. Flailed my arms. Anything. Instead, all I could do was lie there. I couldn’t even scream anymore. It was an incredibly strange feeling. It didn’t last long, though, because I soon blacked out from shock. I woke to Cassie patting me on the cheek. “Wake up, Miss McKenzie, we haven’t finished our lesson yet.”

“Sorry, teacher.” At least, that’s what I tried to say. My mouth moved, but no sound came out. “Ah. I’m afraid that now that your lungs are no longer working, speaking is no longer an option. Just try to pay attention. Your mouth is connected to the trachea, or windpipe, which splits into two bronchi connecting to the lungs.” She cut through one of the bronchi and pulled out the lung through the bottom of my ribcage. “Lungs remove the oxygen from the air you breathe in and pump it into your blood stream.

They also absorb carbon dioxide from your blood and release it back into the air, which you then breathe out.” She removed the other lung as well, followed by my trachea. “Now we can finally see the esophagus, which transports the food from your mouth to your stomach.”Five seconds later it joined my other organs on the floor. Now all that was left within me was my heart, still merrily beating while suspended in mid-air. Cassie flipped me over again and started pulling the layers of muscle tissue off of my back. When she’d removed them, she bunched them up and threw them into a corner of the room. She turned me back around and I looked at myself in the ceiling mirror.

Below the neck there was nothing left of me but my ribcage, spine, pelvis and heart. “What a beautiful skeleton you have,” Cassie said. “But the illusion isn’t quite complete without the rest of it, is it?” She gathered the bones of my right and upper left arm, then started deboning my lower left arm. “I guess I’ll have to give these up now, huh?” Cassie said, looking at her – or rather, my – legs. “Oh well, back to being short.” She switched back to her own legs the same way she had previously and started removing all of the bones from them as well. Soon she had a whole pile of bones lying before her on the bed, the discarded limbs lying on the floor. “Let’s see, how did that song go again?”

Cassie started humming, then singing as she remembered the tune. “The foot bone’s connected to the ankle bone–” She placed the bones of my left foot on the bed in roughly the correct position. “The ankle bone’s connected to the leg bone –” She put down my lower leg bone above the foot. “The leg bone’s connected to the knee bone –” My kneecap followed suit. “The knee bone’s connected to the thigh bone –” There was a bit too much space for it, so she moved the other bones a bit closer to me. “The thigh bone’s connected to the hip bone –”

She stopped singing and continued speaking normally. “Check. From there on the song goes onwards to the head, which is all in place already. Strangely, the song doesn’t mention the arms at all, which just goes to show you that you shouldn’t rely on folk songs for in-depth anatomical information. Still, I think we can make something up.” Cassie started singing again, placing down bones as she sung.

“The finger bone’s connected to the hand bone, the hand bone’s connected to the wrist bone, the wrist bone’s connected to the arm bone, the arm bone’s connected to the, uh… upper arm bone –” I lifted my eyebrow. “Oh shut up,” Cassie said. “You try coming up with a song on the spot.” She positioned the bones on the other side in silence. When she went to place the bones of my right arm, however, she paused. “Now that we have you in this state, we might as well see if this works in real life as well in the cartoons.”

She sat down and started using my ribcage like a xylophone, the two arm bones serving as hammers. She tried playing a tune, ‘tried’ being the operative word, since the result couldn’t be called music, even under the most generous criteria. “Hm, not quite what I was hoping for,” she said. She put the arm bones back where they belonged and picked up two of my leg bones instead, trying again. The result was the same. “It appears you don’t have musical bone in your body, Miss McKenzie,” Cassie giggled. Had I had any airways I would have groaned, but given my disassembled state I had to settle for an eye roll, though I don’t know how well it came across with only one eye. She replaced my leg bones and looked at me. “You’re almost a complete skeleton,” she said, obviously referring to the fact that my face was still attached to my skull. “Nothing we can’t remedy, though.”

Lifting my head, she made a vertical cut along the back of my head and started peeling off my face, which she discarded as well. Next, she went to work cutting away all the other bits of flesh she could find: first my throat and the bottom of my mouth. With those out of the way, she removed my jawbone and picked it clean, removing my gums and anything else still attached to it. I experimentally moved my tongue, which looked really freaky now that I had no lower jaw. Cassie saw this, grabbed it and cut it off. She stripped the roof of my mouth as well before replacing my jawbone. Next came the sides of my head. Everything went quiet as she removed my only remaining ear canal.

A few minutes later, I couldn’t feel anything anymore. All that was left of me was a brain, an eyeball and a heart inside of my skeleton. Cassie stood up, grabbed a notepad and pen from my desk and started writing something. When she’d finished, she turned around the notepad so I could read it.

I’m going to remove your brain now. To do so, I need to briefly disconnect your other eye. Don’t worry, I’ll put it back in a second.

I felt her fingers wrap around the remains of my brain. She severed the brain stem, gave a tug and everything went dark. Robbed of all of my other senses, the only one I had left was touch. My entire world now consisted of her hands cradling my brain. I thought I’d been helpless when she’d just removed my limbs. How wrong I was. I was beyond helpless now, and I was strangely okay with it. I knew Cassie was the one that did this to me, but I trusted her. If anyone was going to have complete control over me like this, it was going to be her. I’d never been in love before, but I had a strong suspicion that this was what it felt like. I tested the words in my head (or out of it, as the case might be): I loved Cassie. The words felt right. I loved Cassie and as soon as she put me back together I was going to tell her.

The light was almost blinding as Cassie connected my eye back to my brain again. Lacking the ability to close my eye or even blink, I could only wait until things darkened down. After a few seconds, things came back into focus. I was now looking down on my own skeleton. She’d replaced the top of my skull, the cut having disappeared as usual. It was a pretty nice skeleton, if I do say so myself. Suddenly, the edges of my vision started going dark. Now that I was disconnected from my heart, my brain was starting to suffer from oxygen deprivation, or something along those lines. But how in the world was I going to indicate this to Cassie?

Fortunately, I didn’t need to. Cassie realized the problem on her own and placed me in my ribcage next to my heart. It was certainly a unique viewpoint, my ribs forming something of a vaulted ceiling above me. The tunnel vision faded, which meant that the invisible arteries connecting my heart and my brain must have regrown. Cassie left me lying there about thirty more seconds before placing my brain and eye on her spread out left hand and grabbing my heart in her right. I felt a sensation I couldn’t quite describe as she pulled the assembly from my ribcage. She set me down on the dresser and picked up her camera again, first taking some pictures of my skeleton and then took some shots of what was left of me. She wrote something on the notepad again.

Since your heart is still beating, I’m going to assume you’re still alive. I wonder how much you weigh in this condition.

Cassie carried me downstairs to the kitchen, searched a couple of cabinets until she found the kitchen scale and placed me on top of it. She lifted up my eyeball so I could read the display. 17 ounces. I guess that’s all that was needed for there to be a me. Just over a pound to form the essence of Susan McKenzie. I briefly toyed with the idea of going on one of those weight loss programs on TV like this. I’m sure they’d have a heart attack. Hey, no pain, no gain, right? She carried me back upstairs and lifted up one side of the blanket, causing all of my bones to tumble onto the floor. She then sat down on the bed, picking up the notepad again.

Now that you’re so small, there’s one more thing I want to try.

She lay down with her feet pointing at the wardrobe mirror, spread her legs and started fingering herself. One finger became two, then three, then four until she worked her thumb in as well. She bent forward in an attempt to get as much of her hand into her pussy as possible. She managed to get it in up to the wrist. She fisted herself for a while and then hooked the fingers of both hands into her pussy, pulling it wide open. She repeated this process a few times, trying to stretch herself as much as possible. Was she planning to do what I think she was? Confirmation came when she picked me up and positioned my heart against her gaping hole. She was going to stuff me into her pussy. I watched in the mirror as she slowly squeezed my heart into her depths. After a minute or so, my heart had disappeared inside of her, but even after she’d pushed it in as far as she could, there wasn’t going to be enough room for the rest of me. Cassie realized this as well and reached down to pick one of my bones off the floor, which she used to push it along further. It was slow going, until the bone suddenly shot inward, which probably indicated that my heart had cleared her cervix and was now lodged in her womb. Tossing the bone back among its brethren, she grabbed my brain and started stuffing it into herself as well.

The last piece to go in was my eyeball, which she only inserted far enough so it was just inside her pussy, which was acting like a giant eye socket. In the mirror, I could see Cassie frantically rubbing her clit, and felt the rhythmic contractions of her vagina walls on my brain which signified her approaching orgasm. When she came, her pussy lips closed like vertical eyelids, leaving me in the dark for the third time that evening. Her vagina gave me a tight squeeze before relaxing again. I pondered that this must be what babies feel like: warm and safe in the darkness of their mother’s tummy. And I had to admit, I’d never felt more safe in all my life – the part I could remember, anyway.

After what I think was a few minutes, I felt her walls start to spasm again, shortly followed by another orgasm. I counted four more after that one, after which everything calmed down. She must’ve gone to sleep. I figured I might as well. After all, I was going to need my energy for tomorrow. I couldn’t wait.
