Monica was only slightly startled when she felt Kevin kneel down next to her in front of Simone. She knew he should be home soon and she was not sorry...he was there. She let Simone's nipple slip from her mouth long enough to greet Kevin with a naughty smile before returning to her station. Kevin quickly joined in, first kissing his sister's other breast and nipple, then licking around the areola then finally drawing the nipple into his mouth. The only time Simone experienced both of her breasts. "With growing excitement, I asked, "What's that? He was a jerk and hescared me some" Well, as you should remember, I have some cameras set up in the videobooths. If we were to get video of him having sex with a guy, he wouldfreak out!" Bill explained. "Are you up for that? He's one guy I won'tmake you have sex with but if you are up for it, it would be sweetrevenge." That's crazy," I answered, "he'll know immediately that I'm not a girland then he'd probably kick my ass." Not if you are in a. This was my favorite position lately so I didn’t have to look in my sister’s eyes as I performed the unnatural act of fucking them and enjoying it. Dawn didn’t seem to mind as she came quickly, sobbing lowly as she came and then quickly rolling over on her back and hissing at me to “fuck me more” and as I entered her she said, “Fuck me hard like you fucked Evie!” I started slowly, but quickly was in all the way and fucking Dawn with long strokes that I would hold at the top, while grinding. From previous experience I knew that I had about thirty seconds to decide if I was going to allow myself to be ‘tied’ or slip away until the knot stayed outside. While I was thinking about it he was swelling up; knot cock and all. I could feel the knot just inside of me and it was getting bigger. He suddenly pulled back very hard and gave a good hard thrust…hitting bottom in me. I bit my lip and then clinched my teeth hard. There had been some sharp pain with that and I squealed like hell.
