Well, I had really done it this time. Thanks to my lactation/impregnation fetish, I had knocked up first my mother-in-law, who gave birth to my son David in January, and if that weren't bad enough, now my 18-year-old sister-in-law was pregnant with not one, not two, not three, but four babies. That's right, thanks to a prescription mix up, I was the father of five children, and none of them with my loving wife Dana.
I have to say that it was an incredible turn on to know that I had put so many babies into my teenage sister-in-law. I loved seeing her waddle around our house, pregnant tummy sticking out from under her shirts, and, when her sister wasn't home, her pregnant tits, which were already producing milk. Even though she was only about twenty weeks along, because there were four babies inside, she looked like she was about to pop any moment. Admittedly, those first few months had been hard for Darlene, juggling school and all her social activities. The doctors wanted her to take it slower, but you try telling a normal teenager that, let alone one that's hormonal and carrying around four babies. But to her credit, Darlene did finish high school. When she graduated she had to get the XX-Large gown to cover her belly. Now that it was summer, she was more than willing to lie around in our air-conditioned house doing nothing—not to mention that being so big that's pretty much all she could do. There was a staff shortage at the hospital, so Dana often had to work double shifts, but I had taken on smaller case loads so I could be home with Darlene, and more often than not, I would work from home.
On those days, Darlene usually walked around the house naked, her swollen belly and pendulous tits on display. I would often come downstairs to find her lying on our chaise, legs spread, watching TV. The sight of her was enough to get me hard, and I would descend the stairs and position myself between her thighs, then eagerly lick at her pregnant cunt. After making her cum once or twice, I would poke my head around and see her smiling.
"Oh it's you," she would say. "I didn't see you there." Usually by this point one or both of those pendulous tits would be leaking and she would offer them to me, cupping them and pulling on them herself. I would drain first one breast, then the other, all the while rubbing her clit and belly. If she was up to it, Darlene would roll over on all fours and let me fuck her. I liked when she did that, but I was just as keen to spoon her and fuck her from behind.
"Look at you, you little slut," I would whisper when I was inside her. "Look how swollen you are. You're such a slut you have four of your sister's husband's babies inside you. Your pussy sucked all my sperm out and made four babies in your slut tummy and now you're so full of me. I'm in your belly and your cunt."
"Yes," she would groan as her pussy would contract around my hardening cock. "Yes, you've fucked your whore sister-in-law. You've filled her with so many babies she can't take it anymore. I'm so horny I need your sperm in me at all times. I need your mouth on my tits, sucking the milk you put in there. Oh, yes, fuck me, fuck me hard and maybe you'll put another baby in me. Nnnn, I'm cumming, shit, ahhh!"
Then I would either come in her or, more recently on her huge pregnant belly. She said it was better for her than cocoa butter, and it was a huge turn on for me.
Having a pregnant sister around the house was doing some interesting things to Dana as well. She was hornier than ever, and would jump me as soon she came home from the hospital. More often than not, I would wake up inside of her, or to her sucking my cock, at which point I would pull her up to me, kiss her, and roll her underneath me, driving my cock deep into her, until I bottomed out. I would tell her how this time I would make her pregnant with my baby, and she would swell up with milk for me.
It was during one of these times that Dana said, "Hey, babe, I have something to ask you."
Why does she always do that when she's sucking my cock? I wondered. It would be hard to deny Dana anything at the moment. I was sitting naked on the edge of the bed with her on her knees in front of me. She wore fishnet tights and a black under bust corset which proudly displayed her already hard nipples. In the closet mirror I could see that her cunt was dripping.
"Oh, yeah, what's that?" I grunted.
"Well, I was talking to Darlene, about what she's going to do with the babies."
"Do?" I asked. That bought me a few more minutes. "I thought she was going to keep them. I said we'd pay for a nanny so she can go to school."
"She knows that, but...well she was thinking that the babies are going to need a mother and a father in their lives, and she knows how much I want a baby, so she was wondering if we would adopt them."
I had to say, this caught me by surprise, one that Darlene would suggest this without talking to me about it first, and two that Dana seemed so gung ho on the idea.
"You would do that?" I asked, stroking her hair as she renewed her assault of my cock. "I thought you wanted a baby of your own."
"I do, someday," Dana replied after a minute. "But I also want my sister to be able to go to college. And we can provide for these babies better than she can, and you know something, these babies are my blood. I'm willing to raise them as our own if you are."
She looked up at me expectantly.
"So I would be the father of Darlene's babies?" I pretended to mull it over as I stroked Dana's hair and she stroked my cock.
"I guess it would be better than adopting through an agency," I said. "We'd be on a waiting list forever."
"Is that a yes?" Dana asked.
"I'll draw up the paperwork tomorrow." Darlene smiled and straddled me in the reverse cowgirl position.
"Oh, yeah, come on, Seth, fuck me hard, fuck a baby in me. Make me a baby, make my titties shoot milk like Darlene's. Oh god, oh fuck, I'm cumming."
