...I looked at her and she was about to get a serve of juice from John's hot cock too and like me she started moaning obscenities to John..."Fill me c...nt baby give me that hot cock ooh it feels soo good baby ooooh I'm cumming too ooh baby oooh..."Brad must have really been building up because his orgasm didn't seem to stop and neither did mine. I had my cum all over my hand and between my legs as Brad's cum leaked out of my pussy and down in between my thighs... I wiggled some more against him. It was all very much new to me.After a which I started getting bored and all of a sudden a very harsh feeling generated in my body, it was inexpressible to me.And so I started shivering feeling with the feeling of self-satisfaction and in that position, I pulled my sister of her hair as she was sucking my cock and started kissing her in a more wilder attitude.Biting her lips overlaying my hand round her body and holding her as tight as anything can be while she was giving me a handjob.I started. “ This turning you on isn't it? Here we are wanking and groping while we talk dirty about my daughter like I know you love too, but this time she is right here. I could get on my knees by her bed and suck you till you shoot your hot cum in my mouth and she would never know, or maybe you would prefer it that I leant forward bent over her bed while you ram your cock in me as my tits sway over her sleeping body. I bet you could tell me to touch her sleeping body while you watch and wank and she. "But no cheating," she said, moving her hand back to herself. "No masturbating in the washroom." Deal," I repeated, my head spinning with the delicious visuals I was already imagining occurring in under four fours.Suddenly her phone buzzed. She looked at it and sighed,"What?" I asked."Mistress Alicia won't take no for an answer," she began, "she expects me to show up at her friend's Halloween party, even though I've already told her that this was a commitment I couldn't break."Shit, I thought.
