Motherfucker: Part 3 by rat_race

Jenny reached across and grabbed hold of her brother’s bare partially-erect dick, and she began squeezing it and feeling it out, as well as fondling his balls.

“I started doing it a few months after she kicked dad out of the house, and then filed for a divorce. And I’m not the one who started it either. She did.

“Mom walked into the bathroom while I was showering one day. Of course, you weren’t at home at the time. And she took off all her clothes and stepped into the shower with me. And she asked me if I wanted to touch and feel out her pussy.

“And before I could answer her, she had her hand wrapped around my dick. And she told me that she wasn’t going to take ‘no’ for an answer. And of course, I felt much more comfortable with the idea of letting Mom see and touch my dick than I did with the idea of me showing it to any other women, because Mom had known all about my hypospadic penis ever since I was born.

“So while Mom was squeezing my dick and playing with it, my hand just automatically shot out into her bare crotch, and I started groping away at her pussy with my fingers. And at that point, I knew there was no turning back for either of us.

“And that’s how Mom and I ended up fucking in the shower.”

“And you didn’t just fuck Mom once that day, now did you?” Jenny prodded Greg.

“How do you know that?”

“Mom told me so herself. She told me about everything that took place between you and her that day in the shower and afterwards. Mom was feeling super-ashamed about what she did with you that day. About how she got so horny that she went ahead seduced her own son, and took his virginity. And she spilled the beans, pouring her heart out to me. So I know that you didn’t just fuck Mom once that day, now did you?”

“No, I didn’t. After Mom took my virginity in the shower that day, I followed her straight to her bed, and we made love to one another. Basically, Mom and I fucked two more times before she was finally done with me that day.”

“Afterwards, I felt so filthy and depraved. I mean, of all the people in the world that I could imagine myself having sex with, my own mother was the last person I would ever think that that would happen with.

“But I also couldn’t deny the fact that it did actually happen that day–and that I wanted to keep on fucking my own mother, whenever she needed me to help her get her rocks off.”

“I know exactly how you feel,” I said to Greg.

Jenny said to Greg, “You do realize that if you keep fucking Mom like you’re doing, you’re probably gonna get her pregnant eventually, right? I mean, Mom hasn’t hit menopause yet.”

“What are you talking about? She’s on birth control.”

“Yeah, if you can call it that. It’s called the rhythm method. It’s the same thing the Catholics have been using for years. Buy it’s only about 75% effective, and those aren’t very good odds, if you ask me. Just think about it for a moment. If you keep fucking Mom over the course of a year, there’s a 1 in 4 chance that you’re going to knock her up. Then, what are you guys gonna do?”

“You’re wrong about Mom. She doesn’t use the rhythm method. I know that for a fact. And I don’t just go to her bedroom, unless she invites me there first. And that’s because Mom normally doesn’t invite me into her bedroom until she’s feeling super-horny and most-likely ovulating. Then we’ll usually fuck several times a night for four or five nights in a row, before Mom will go down to the pharmacy and get a morning-after pill to take, so that she doesn’t end up getting pregnant. That’s her version of birth control.

“Then Mom and I will agree not to have sex for the next three weeks, or so–and I’ll just turn to my boyfriends for sex, whenever I get feeling horny–until Mom starts ovulating again, because that’s the only time when she’s feeling so horny that she wants me to go ahead and sleep with her. By the way, she admitted that to me herself. And that’s when Mom’ll just walk up to me and say something along the lines of, ‘It’s time for you and I to make love tonight, don’t you think?’

“And so far, Mom’s version of birth control has worked like a charm for us. I mean, Mom’s still not pregnant, is she? And we’ve been fucking periodically for well over a year now.”

Jenny jumped in to warn Greg, “Be careful, big brother. You’re playing with fire. And you know that.”

“Yes, of course I know that. But I also can’t stop myself, either. And if I get burned, then so be it. All I can say is that it’s an incredible turn-on knowing that my own mother is encouraging me to fuck her and fertilize her ovulating womb. And I’ll jump at the chance to do that anytime it comes along. Now I ask you, what son gets to do that to their own mother? I feel truly blessed.”

Greg caught me by surprise when he abruptly shifted his attention from Jenny to me, as he said to me, “I can’t believe you don’t mind me fucking your girlfriend in front of you.”

“Well believe it or not, that’s because your little sister obviously wants you to fuck her in front of me. So who am I to deny her that?”

“Wow! You’re one hell of an understanding person. That’s all I can say.”

“No, I’m not. But Jenny’s obviously wanting me to try out cuckolding with her, which can really enrich a person’s sexual relationship, judging from what my mother told me about her own experience with cuckolding my father, back when he was alive.

“Besides, I want to watch you cum inside your little sister’s pussy. Just so you know, I fucked my own little sister the last time I was in town visiting Mom.”

“Wow! That’s wild!” Greg said, and then asked me, “By the way, you’ve got a really nice-looking dick on you. Would you mind if I touch it and feel it?”

“Go right ahead,” I told Greg, without even thinking about it.

I’m normally not into having sex with guys. But there was something very disarming and gentlemanly about the way that Greg asked that question that made the idea of my having his hands touching and feeling my dick seem okay. And so while Jenny continued playing with her brother’s dick, he began fondling mine at the same time.

And at that moment, Jenny strategically reached up and retracted her big brother’s foreskin all the way down around the base of his dick-head, so that she could get a close-up view of her brother’s hypospadic urethral opening that had previously been hiding in the fold of his foreskin on the underside of his dick-shaft.

“You know you don’t have to fuck me, if you don’t want to,” Jenny said to Greg, offering him a way out, so that he could save face if he was wanting to. “But I sure wish you would. I’ve been fantasizing about you fucking me for years. I can’t believe you haven’t fantasized about fucking me.”

“Who says I haven’t?” Greg remarked. “Just ‘cuz I didn’t act on my fantasy doesn’t mean that I didn’t have one. I mean, what brother doesn’t fantasize about what it would be like to have sex with his own sister. Especially when that sister is as attractive as you are.”

“You’re a good-looking stud yourself,” Jenny said, lying back down on her back on top of the bed, and spreading her legs far apart. “Now get up here on top of this bed and fuck me hard. Can you do that for me?”
