I Catch Her Humping Again

My fantasy over 18 stepdaughter is helping me cook breakfast before the big volleyball tournament. I catch her grinding her privates on the rounded island in the kitchen again. She is spanked and degraded. Then I get over it and allow her to, she says she prefers to do it naked. I become aroused and slip my erection between her privates and the counter. She continues grinding until she makes orgasms on my dick, causing me climax too.
