Robby and I had been fuck-buddies, friends with benefits for almost a year- ever since a horny, lonely encounter a the grad campus bar. It was a fantastic relationship. No strings. Something that let each of us work off the frustrations of grad-student life and dissertation work. We never saw each other on campus, since our departments were on opposite ends of the sprawl, and we didn’t need to meet socially. We’d just hook up once, maybe twice a week for a solid fuck. Or night of fucking. Occasionally a weekend of fucking. And it got better as we learned we were both a little kinky. A little tie-up now and then really got the orgasm hot - no matter which one of us was bound.
So, after a particularly rough week of exams and a proposal defense. I was more than willing to be bound up for a rough fuck and forget everything. The tape over my mouth was new, but I rolled with it. It helped to force me to let all control go. Besides, Robby had already bound my wrists and legs spread, so it wasn’t like I could’ve stopped him.
I was dripping wet when he shoved his sheathed cock hard into me, and let out a muffled moan as he started fucking me just like I needed. It was good. Very good.
But then he paused halfway in me and said, a little breathily.
“I’m tired of this condom shit. I want to feel that tight pussy of yours bare. What do you say, Cassi?”
He wasn’t waiting for any reply, though. He withdrew from me and I heard the condom snap off. Before I could even squirm, his hands were back keeping my thighs spread wide as he thrust his bare cock home in me. God that felt good. It made butterflies dance in my stomach to feel his skin against mine, deep inside. We’d known each other long enough that I knew he was clean, but it was still the extra precaution on top of the pill.
“Fuck that’s good,” he was panting, talking between thrusts. “Oh, I should’ve done this long ago, Cassi. But I had to learn you first.”
“Had to learn your cycle. Had to figure out what pills you used. Had to find a fertility pill that looked close enough and replace them two weeks ago.”
I stiffened, not believing his words. He kept fucking. If anything harder, deeper.
He leaned in and whispered in my ear.
“I’m going to knock you up, Cassi.”
I shook my head violently and tried to move off him. He held me tight.
“I’m not even a student here. I’ve never been in the chem building. I just came in from town to fuck you. To get you ready for this.”
I was incredulous, wide eyed, desperate to get away, but utterly unable to do so.
“You’re ovulating now. I know it. I could taste it on your cunt. And I’ve got you all weekend. I’m going to fuck you over and over, as much as I can. Fill you with my cum again and again. Make sure you take. I’m going to fucking breed you. And then. You’ll. Never. See me. Again!”
The last words were accompanied each by a vicious, deep thrust of his cock. And at the last he hilted in me and came. Is cum pumped into me - into my fertile, helpless womb, pulse by pulse. I could feel my entire world drowning in his flood.
