Michael fucks you like a dog

With augmented strength, Michael picks you, spins you around, and pushes you to the ground. You raise your ass automatically, offering him easier access and panting like a bitch in heat. He grabs your hips and mounts you like a dog. You scream as your cunt takes the entire length of his member in one, smooth motion, filling you in a way other men have never managed only to pull out and leave a gaping absence in its place. Then he thrusts back into you, repeating the process over and over, pounding away at your pussy like he has every intention of knocking you up. Suddenly the condom case on the wall seems like a really good idea.

"Oh fuck!" you scream. You tilt your ass even higher and move back in time to meet his thrusts. He adjusts the angle of his cock slightly, and suddenly he's rubbing against your clit. "Oh, yes, that's it. Fuck me like that. Fuck me hard. Make me your bitch!"

If Michael's surprised by such foul language coming out of a 19-year-old's mouth, he doesn't show it. Instead he just grunts. He moves his hands from your hips to your tits, squeezing and playing with them in a way that feels sinfully good. You wonder for a moment if the walls of this lab are soundproofed or if others can hear your loud, uncontrollable moans.

They're certainly exciting Christina, who until now has been getting herself off to the sight of you and Michael fucking like dogs. Now she crawls over to you and lies on her back, positioning her pussy just in front of your face.

It doesn't take a brilliant scientists to work out what to do next. That's good, because you're not a scientist, and the pollen has robbed you of what brainpower you did have. You can no longer string together coherent thoughts, even your name escapes you at the moment. All you know is that you can smell something good in front of you, and you want to taste it.

You lower your head slightly and begin licking at Christina's cunt, which is every bit as aroused as yours. Her prim-and-pink labia are a bright red, and her clit sticks out of its hood almost grotesquely. Christina is whimpers and squeals while you go down on her. The two of you have had sex before, but only play-acting, really, or as part of threesomes like this one. Except never like this one. Christina's pussy is suddenly the best thing you've ever tasted, and you've never wanted anything more in life than to eat her out while you get filled from behind.

Michael's cock ploughs you without stopping for a good ten minutes, by which time both you and Christina have come. Your body is trembling and tired from being pounded in the same position for so long, but you can't stop him. Despite the slick layer of sweat now coating your body, he maintains an iron grip on you, and all you can do is lie down, your face pressed against the ground, and take it like the bitch you've become.

More animal sounds issue from his throat, growls and groans as you feel his cock spasm and unload his seed into the sheath surrounding it. He slows, maintaining a steady but decreasing rhythm until finally pulling out. Your pussy gapes, its once-tight lips now wide open and inviting. You wonder if, after they retreat from their swollen state, they will also tighten up again or if you'll always be a loose cockslut from now on.

Although you're no stranger to sex or even threesomes, you're surprised by the thoughts running through your head. Cockslut? When did you start using that language?
