One morning, having taken her home after swimming, I turned to give her the regular goodbye kiss as I was about to leave. We kissed and, somehow, the ...iss lingered just a bit longer than it perhaps should have done. We looked at each other and kissed again – and again. That too became a more regular occurrence – all quite innocent though. Then, over Christmas, we visited some relatives for a f****y gathering. We played cards and I found myself sitting on the floor facing Doreen. She was sitting. Erica walked over to Tiffany. She casually took the riding crop from hercollar, and began to fondle the bound girl's breasts. Tiffany squealedthrough her gag. "Well now. Two girls chained in the Dungeon.

I was rubbing her clit as I fingered her and knew she was going to cum soon. her hips were bucking a bit and then she clamped my arm between her legs and went rigid. She was bucking her hips involuntarily as she had a long drawn out orgasm. I felt my sister stir a bit and she rolled against me. I was getting a bit nervous and sat still for a few minutes as I fingered mom slowly. She was still stroking.
