John Trimbell woke up with a start in his living room. He had fallen asleep on the couch while waiting for his wife, Judy, to get home. She was out fucking her boyfriend while he waited at home. He loved licking her cum filled pussy when she got back. He didn't mind her having a lover, especially since he had started fucking his eleven year old daughter, Trish, with his wife's approval at that. Of course they were no strangers to incest, being brother and sister as well as husband and wife. His daughter, who had just turned eleven when he started fucking her, had just begun to show with his child, and she was hornier than ever. He smiled thinking of her having his baby, maybe it would be a little girl he could fuck as well. He was jolted out of his reverie by the sound of the door opening; his wife's car must have been what woke him up.
"Hi honey, how was your date?" he asked as she came in and kissed him on the lips.
"Lie down and I'll let you taste for yourself," came the reply, with a smile.
"He quickly lay down on the couch and she straddled his face, hiking her dress up and pulling down her panties before sitting on it.
"I wore those just to keep it in for you, I know you like licking his cum out of me. You should try it right from the source sometime."
His cock, which had been spent earlier from a session fucking his pregnant daughter sprang back to life.
"Hmmm, I'll have to do something about that," smiled his wife as she spotted his erection.
"Maybe you could sit on it after my face?"
"No, I don't think so."
"Why not?"
"You might try to cum inside me, and I'm trying to have my boyfriends baby."
His cock got even harder at the thought of her cuckolding him and getting pregnant. He really liked the thought and it had inspired some fantastic lovemaking sessions with the married siblings.
"I can see how you love that thought," she purred as she started to stroke his silky yet rock hard erection.
His tongue got to work licking up his wife's lovers semen.
She continuted, "I'm fertile today, and he came so deep inside me. But I'm not going to fuck you until I get pregnant. I may want to have more of his babies. He is jealous of me and you, so I came up with a solution that would work for us. You have had two children, your daughter with me, and your child with your daughter. And I am going to have two of his children. Since you have already had yours, he suggested and I agreed to castrate you."
As she said that his cock immediately began to spurt.
"Ohhh, you like that idea don't you?" She purred, rubbing his semen into his cock, and then bringing her hand to his mouth so he could lick the rest off.
"Mmmm-hmmmm," He agreed, spent from his orgasm, but still semi-hard.
"I wasn't sure when he first suggested it, but now that I see how much you like it I'm convinced. It's going to be so hot to see you without those balls dangling below. And don't worry, we can get you hormones to get you hard again. It's a good thing we have some sperm stored in case you want to get your daughter pregnant again. If you do that though I may just have another one myself."
A few days later a package arrived in the mail. Ripping it open with excitement, Judy produced a strange looking implement.
"What is that?" he asked.
"It's an elastrator, it puts a rubber band around your balls that will cut off the blood supply and castrate you."
He felt his cock swelling at the thought.
She said, well you need to take a couple of weeks off of work, because you will probably not be able to walk while this is going on.
He grew harder.
His wife and daughter were gathered with him in his bedroom.
"This is going to hurt quite a bit, so I need your help to make your father feel good while we take his balls."
"Do we have to? I like fucking daddy"
"He can still fuck you, he just won't be able to get you pregnant."
"But I like having Daddy's babies"
"Well you need to finish school. If you still want to have your fathers babies afterward we have sperm stored up that you can use to get impregnated by him. But you can always take a lover to get pregnant. I'm actually pregnant right now"
She had just taken a pregnancy test that revealed the news last night. What she hadn't revealed, was that her boyfriend was black, boy would her husband be surprised at that. But he was a true cuckold and would take care of the baby like his own.
As his wife slipped his balls inside the rubber band that would remove his manhood, his daughter started stroking his cock. Her little titties, which had only barely gotten to the point where they were distinctly tits and not just the flat chest of a child, had rock hard nipples. Those and her slightly showing belly were helping him focus on what a little cum slut she was, instead of what his wife was doing to him. He jumped as she slipped the rubber band off the end of the elastrator and it snapped tight around the base of his sack. He saw her loading another one on and looked at her quizzically.
"I'm just going to slip one more on to make sure"
"This doesn't hurt at all he told her."
"It takes a bit but then it begins to hurt more. Once your daughter isn't enough to mask the pain let me know. I got you some percocet, that will help you through the rest."
At that moment his daughter slipped her wet, pregnant pussy over his cock.
"Mmmmm, daddy, you are so hard. Are you getting off on getting castrated? Are you getting off on having impregnated me? How about on mommy having another mans baby?" She moaned, talking dirty to her daddy as she rode him.
His cock just kept getting harder as he fought to keep this fuck going. He loved hearing her talk like a little slut, almost as much as he loved her being a little slut. He moaned and pulled her down to kiss her, and she moaned back into his mouth.
"I am getting so turned on by this daddy, can I please take your balls?"
"Honey, you are, you're helping mommy do it."
"No, I want to do it myself."
"Well, how are you going to do that?"
"I'm going to get a knife from the kitchen and slice them off."
His wife, who was watching the whole thing had started fingering herself with all the talk, and now joined in, "The bands would keep you from bleeding out, and the whole recovery would probably be quicker."
He responded by shooting his final fertile load deep in his daughters willing cunt.
Judy returned with her sharpest knife, it was brand new from one of those late night TV commercials and was supposed to be able to cut through a battleship or some such nonsense. She wondered if they would make a commercial about cutting off balls if she pitched it to them and smiled at the thought.
Handing the knife to her daughter, she pulled her husbands sack out for her.
"It's true, the bands are starting to hurt now."
"That means it's working, but now your daughter is going to unman you."
With that Tris brought the blade to the base of his scrotum, just below the rubber bands that were slowly castrating him, and accelerated the process.
John moaned as he felt a sharp pain in his scrotum and felt his balls come off his body. His cock, which had remained hard with the thought of his impending castration, began to spurt again.
Despite the pain he looked at his incest impregnated daughter and cuckold pregnant wife and said, "I love you." He felt truely emasculated by them as his wife slipped a percocet into his mouth and gave him some water. As he the pain dulled and he drifted off to a dreamless sleep his last thought was that he was a eunuch now.
