A second orgasm gripped her and she held my hair in both hands while she rode it out under my tongue, she was still coming as I quickly changed positi...n and thrust myself into her wetness,"OH FUCK YES" she screamed, "You're filling me Gary, you're fucking me"I could only grunt in reply, all my senses were fixed on my prick inside my sister's body, her eyes were set on mine, we'd both had lovers before, hell we'd both been married, but nobody had what we did between us, the sheer intensity of it. We burst into laughter as she told me to change my clothes. I went into the bathroom and locked the door sat on the pot and started pissing, asI was pissing she entered the room, my piss stopped there and then not a drop coming out because of fear ,But as u guys know how shameless she is she continued to stare , I threw the tissue paper roll at her and told her to buss off she closed the door and i changed and went outside she told me that she had forgotten to tell me that the lock was broken.. It was so hot. Here was my girlfriend just pounding me with her dildo, while I rubbed my clit faster and faster. It felt so wrong but not normal wrong. It felt naughty wrong. Wrong and right. The thought of it alone was intensifying the pleasure. My head fell back and I closed my eyes, vigorously flicking my fingers over my clit with different pressures. All the while, a dildo sliding in and out of me. “You like being fucked by this cock?” she asked me, with passion in her voice.Out of. She must not have remembered what I said about rhetorical questions, so out came my hand and spanked down on her very puffy and very exposed pussy lips. Before she could utter any kind of sound, I attempted to shove my entire hand deep into her clenching pussy. I chuckled to myself as I saw about three quarters of it twisting and stretching her poor, battered pussy. No more squeals, but a long continuous low moan emanated from her throat. Her ass was moving in slow, grinding circles attempting.
