The door shuts and I start to panic. My heart races as the room turns black again and the silence is deafening. I don't dare scream for I've learned m... lesson the last time I did that. I still have marks from that lesson. I hear screaming in another room nearby from my guest bedroom, their not screams of fear but of lust. For what seemed an eternity, I lay there and wait. Wait for the screams to stop, wait for you to come back and release me. Finally I hear the front door open and close. My. "Shit, mom. You are making me cum again," Billy let out loudly. "Cum all over your mom now," Erin replied. Everyone smiled, and Billy pulled out. He shot his cum all over his mom, and the whole incest thing didn't seem to bother them. For whatever reason, I loved that. Then Shawna glued her lips onto mine. We made out, as Billy got with his mom too, and they made out too. It was odd to me, but it so very satisfying to me at the same time. I wrapped my arms around her, and she did the same. I. We stood up and I bent her over the couch, before slamming my cock back in her soaking pussy, man it was tight, I picked up a hard rythem, and she was using her hands to push her body back onto my cock, each time my balls slamming against her ass, I wondered if anyone walking past could see our shadows through the curtains, or if they could hear her, she told me to stop for a second, reached in a bag in the corner and pulled out a bottle of lube, she quicker sucked my cock before rubbing some. Nothing. I said it again. “Daddy please stay with me I’m scared,” she said in a whisper. I moved in closer to her until we were spooning. Of course my cock was starting to fill up and lengthen. Heather would not be able to miss it in another minute. I put my hand around her waist but I grabbed instead a handful of tit. Her breasts hang so low that they are down by her navel when she is in this position. Well at this point I wasn’t letting go yet. So I buried my hand in her cleavage outside her.
