Stop Sam

I really shouldn't be doing this, after the initial shock and pleasure of having my sister-in-law riding my cock, I come to my senses and realize this could change my life drastically for the worse. "Sam we can't do this!" I say while I try to push her off of me.

Sam is having none if it, "We already are Dan, and don't tell me aren't enjoying this," she smiles wickedly, "I feel that nice big cock of yours throbbing inside of me."

"But Sam, this would destroy Meg and me!" I protest again, now more forcefully trying to get Sam off of me. I grab her by her thin waist and begin to lift her off my still steel hard rod.

"Damnit no! I'm getting close," Sam slaps me across the face.

Shocked I toss her off of me, my eight inches suddenly exposed to the cool night air. I'm mesmerized for a second by my cock bobbing and glistening with my sister-in-laws juices, then I realize Sam went from crazy, marriage crashing horny bitch one second to dead quiet the next. I look over and see Sam sprawled naked on the ground her head pressed up against the leg of the coffee table. For a second I panic and think she's dead but then I see her small pert breats rising and falling as she breathes. She must have hit her head and been knocked out. I take a few deep breathes to collect myself and realize I can't just leave her like that.
