**Contains: taboo, kink, step-mommy roleplay, handjobs, assjobs, precum play, panty fetish, POV, reverse cowgirl, asshole fetish, cock worship, cumshots** You and your step-mother already have a long established relationship. You keep running your hand up her inner thigh. She's trying to read and pushes your hand away. She reminds you about the family rules. We need to have boundaries, because modern day society doesn't understand what the two of you have. It's not something accepted in society. She tries going back to her book but your insatiable. Such a dirty little pervert her step-son is. Fine. She spreads her legs for you as you leak precum and she plays with it. But she knows what you're really aching for. Her dirty panties. She's been wearing them for DAYS for you. Because she knows how much you love them. Her dirty, stinky panties. You leak precum as she jerks you with her panties. She rubs herself with those panties. But there's something she's been thinking about for a while now.. She straddles you and takes your cock between her ass cheeks. She wants you to cum this way. While she grinds up and down on your leaking cock. But don't worry, this is just another way for you two to play. She's still gonna fuck you whenever you want. She promises you after you blow your load ALL over her ass and pussy XO
