Like stepmommy, like stepson - finally the fulfillment

You & stepmom have a super close relationship. You tell each other everything. Even your most private, taboo thoughts. You reveal your sexual attraction towards your beautiful younger stepsister. Stepmom says it's ok to have these thoughts & confesses her own. Her voice is warm & comforting yet the conversation is extremely taboo. Stepmom suggests they try an exercise today (with her help of course). No more fighting these desires. Experiencing it will be beneficial to your well being. stepsis walks in looking for stepmom. Her new underwear fit too tight. Stepmom says she'll exchange them but to take these off for now & convinces her to get nude. She lets her pose erotically & do things so you can indulge over her body. She is a most dirty, filthy step mommy who would do anything to make you happy...
