You wouldn’t lie to your daughter, would you?

She’s laying on her back, trying to catch her breath. Her chest rises and falls heavily, glistening with your seed, or as she calls it, her ‘baby brother batter.’ She slides a finger across her perky breast, her eyes rolling back as she tastes your cum for the millionth time. Her legs still twitch from her sixth orgasm; you always found her little post-coital spasms cute, to her annoyance.

You know it was her sixth because six of the little green lights on her Seven-To-Heaven collar have switched to a dangerous, throbbing red. A gift for her nineteenth birthday, she was thrilled to show the perverted gift off to her friends… though she’d never tell them her own father gave it to her.

“Fuck, Dad! That would have drowned me!” She looks down her athletic body at the pools of pearly white, marvelling at the volume. She hasn’t noticed the spot on her blushing cheek, rolling down to her neck and the explosive collar clasped tightly around it.

“I lost count, Dad… Daddy,” she remembers herself, her teasing-princess voice like music to your ears. “When you were licking me with that tongue, oh, my god, that tongue…I don’t know if the collar counted it once or twice or what…” You look down at her as her fingers dance dangerously close to her clit. Surely she kept count; it made all the difference. Six orgasms, no matter how strong, were perfectly safe, A seventh orgasm, no matter how light… like the kind your masochistic daughter might have the second she touched herself if she knew it would be her last… that would trigger the explosives in the collar and destroy the wearer. “Daddy?” she asks, her innocent eyes looking up at you. “I’m only on five, right? I can have one more? Please?”

Your cock twitches as her fingers start to tease her lower lips, her pussy slick. You wouldn’t lie to your daughter, would you?

That first night, when she was one break from uni and she came into your room in her cheerleading uniform, you told the truth. When she asked if you thought she was pretty, you told her she was beautiful. When she asked if you liked her body, you were honest, telling her how gorgeous her slender form was.

When she stripped off her uniform and asked you if you wanted to fuck her, you told the truth.You told her what a bad idea it was, how if anyone found out you’d be ostracized. You told her that it was wrong for a girl to want to fuck her father, and it was *definitely* wrong for a father to want to fuck his daughter.

And you told her how you wanted nothing more than to pin her down and fill her with cum.
It wasn’t long, not long at all, before her masochistic streak reared its head. Of course, in your day, snuff fetishists didn’t have anything more complex than a guillotine to play with, and you were used to finding creative ways to strangle someone with whatever was on hand.
The fit, energetic girl who always seemed ready for more no matter how much her dad tried to wear her out was turned into a puddle of orgasmic wreckage when you wrapped a belt around her neck and threatened to choke her if she came. She begged for you to snuff her and you almost did, except you came to a realisation.

You wanted your own demise to be synchronised with your daughter.

You swapped ideas, teased each other. She’d suck your cock while you were driving, trying desperately to get you to swerve into oncoming traffic. You’d fuck her over the edge of a secluded building; you kept in shape well enough that if you decided you were going over the edge, she’d be getting splattered on the ground beneath you whether she had cum yet or not.
Then the fashion changed. Just before she turned nineteen,, people stopped taking poison pills and started using bombs to end themselves. A trippy demise was out, an explosive demise was in, and your daughter knew *exactly* what she wanted for her birthday.

The Seven-To-Heaven Collar. Proudly show the world how much you’ve been getting off and how close you are to death. Green light indicators switch to a sultry, throbbing red when the user cums; seven orgasms without taking it off to reset it and it exploded violently.

She wore it proudly, and her sensitivity skyrocketed. Just sitting and watching a movie together, if a sex scene came on she’d give a little gasp and, sure enough, one of her lights would go red. If she wore it while blowing you, even if she kept her hands wrapped around your shaft, by the time she had ‘sucked out her sisters’ (her words, not yours), she would have two, even three lights red that had been green when your throbbing member had first passed her full lips.

It was the closest she’d gotten to dying, and the closest you two had been to having your incestuous relationship discovered, when she wore it to a work picnic. You both sensed that protecting your reputation was getting less and less important so you hadn’t stopped her wearing it in front of your coworkers, acting like an out-of-touch old man who was blissfully unaware of the significance of his daughter’s collar. Except you hadn’t been able to resist bending her over in the relative privacy of the trees and when you got back, her six red lights had quickly become a point of gossip.

Your daughter spent the whole time flushed, eyes unfocused, on the precipice, your cum oozing out of her tight pussy, her dazed expression making your secretary giggle until you finally showed mercy and reset her collar. No longer close to her demise, she was able to regain a little focus… though you’d had to hire a new secretary shortly afterwards after yours, inspired by your daughters antics, blew herself up with a stick of dynamite at a club that very night.

Now she is in that same state. Her fingers getting closer to her g-spot, her toes clenching the sheets, her hips bucking… if she knew she was on six she’d already be cumming and then…
You take her hand, softly, and she whimpers. “Please, Daddy…. I just need one more. Can I have one more?”

You’re already hard again, partly from your beautiful, writhing daughter begging to cum, and party from a primal part of you knowing it will spell your demise if you let her.
You wouldn’t lie to your daughter, would you?

You lean down and kiss her. “I think we can both have just one more.” She smiles, wrapping her long legs around you. She sighs with joy as you slide inside her tight, young pussy. She bites into your shoulder as you slowly drive deeply into her, not wanting to rush this, your daughter’s final orgasm.

“Ha-oh-fah-fuck…” she cries, her fingers clenching your hair.

“Language,” you chastise jokingly. She rolls her eyes, first at the dad-humour, then from the pleasure. She feels incredible; she always does, her movements perfectly in synch with yours.
She probably gets it from you. She starts to whimper and moan.

“Careful, honey. If you explode, they’ll have to bury us both.”

She giggles with ecstasy. “They’ll… fuh… fit us both in… ha… the same shoebox…”
You roll and lift her onto you in one movement. She laughs, and then moans as she impales herself on you.

“Tired already, old man?” “I just wanted to see the look on your pretty face. I love you, princess.” “Aww, I love you, Dad!” Her hips roll with grace and agility as she clenches her perky breasts, her back arching. “You want to see… ah… see the look… when I cum? Big number six?”

You reach up and place a hand on her cheek. “No, the look on your face when you realise.” Your balls are tingling and tightening now, you know if she asks nicely she’ll get a pussy full of cum as her last request. She’s confused for a second, then you turn her face to look in the mirror. “Oh, fuck, daddy…” She sees the solitary green light, and all those throbbing reds, and it’s too much. “Oh, fuck, no, Daddy, I can’t… fuck… I can’t stop…” “Don’t stop for me, babygirl. Explode for your old man.” “Hunh… fuck… Daddy, I’m gonna explode… fill me fill me fill me quickly FILL ME!”

She flops forward, breasts mashing into your chest, her tongue plunging into your mouth. All you can feel is her spasming pussy milking the last orgasm from your cock as she pulls back enough for you to see her biting her lip and looking at you with raw lust as the last green light turns to throbbing red and…

KA-BLAM!!
