I have a secret with my stepson that I can't tell anyone—I am his sex slave. He touches my big ass every day, using it to satisfy his strong sexual desires. Lately, my husband has been away on a work assignment, leaving us alone more often, deepening our forbidden relationship. I know this is wrong and illegal, but I can't resist. Each time my stepson slowly teases and pleasures me, my heart trembles uncontrollably. This sensation is something I can no longer stop.
