I concentrated on making my cock jerk inside her exactly to the beat of the music. The music stopped and I remember we just lay still, deeply and inti...mately coupled, breathing hard with excitement, and when a new record started we immediately continued our sexual dance, her vaginal muscles clenching and unclenching my cock to the rhythm while I twitched my shaft in response. A real sex dance!She moaned in my ear and then whispered she was cumming and I couldn't hold back any longer either. We. I couldn't hear anything coming from inside. I took a few steps closer towards the door. "Mark?" I said, but there was no answer. I carefully pressed my ear against the door. I could hear a muffled sound but I couldn't quite make out what it could be. Slowly, I turned the doorknob and opened the door a bit. Just enough for me to see in without alerting Mark. I couldn't believe what my eyes were seeing. Mark was lying on his bed with just a tshirt on, and stroking his cock. I moved in a little. He kissed her back and smiled. At least she still has to stand on her tiptoes to kiss me, he thought. He reached into his back pocket and took out a small box. “I have one more gift for you, niece” he said as he handed her the little package. She took it from him and carefully opened it. Inside was a gorgeous necklace of gold with a diamond studded charm. The charm was a word, “niece”. Her eyes were as wide as he had ever seen them. The last time he remembered her being this surprised was when. Before leaving the meeting room Allison was asked to pull down her pants and bend over the edge of conference room table. Seeing all their serious faces surrounding her, getting impatient... her trembling hands obeyed even before her brain had made up its mind. Fight, flee or freeze, her dumb body chose freeze. The next hour was spent giving her usual unenthusiastic blowjobs while getting her ass groped and pussy fucked. She tried to look strong and professional but was betrayed by the tears.
