She was smoking hot, very pretty and a perfect ass for that position. Couldn't understand a word they spoke.....so...I will apply my on scenario. She is his convenience fuck. Maybe even his little sis. He was screwing for himself for sure. Driving himself to the edge then changing the rhythm in order to ride the edge of the orgasm without going over. What man would want that to end? She was content to allow him to pleasure himself for as long as he wanted to. What fun it wold be to have a gorgeous little sister like her that was willing to be a convenience fuck.
