Just grit your teeth and take it.

After a few minutes of being fucked, any idea you had about it feeling good is starting to vanish. Your ass quickly start to sting as Mike thrusts in and out of it. But you know it's too late to turn back now. The only way this is going to end is with an ass full of cum. You just clench your eyes, grit your teeth, and take it.

You start whining a little out of discomfort but make it sound like moaning, hoping that will help Mike finish sooner. It doesn't take too long, though, for your moans to turn into "Owww"s. As you're fucked harder and faster, you collapse forward into the back of the couch. Mike starts groaning as he thrusts up into you at a furious pace, then slams into you, moaning as you feel your ass filling with his hot sperm. He thrusts a few more times and laughs, "Oh yeah." When he pulls out, you feel his warm goo dribbling out of your bottom. Behind you, you hear Mike zipping up his pants, and saying, "Wow. Thanks, again, Kristy." And he's gone before you turn back around.
