Blowing My Step-Son Before My Husband Gets Home!

This purple bikini I just bought is so cute and will be perfect for my vacation with my husband. But when I went out to the living room to find my husband, he wasn't there! His step-son was sitting on the couch looking a bit upset. I asked what he thought of my bikini but I don't think he cared much. He asks me to sit next to him on the couch, and so I figure this is a good time to ask about his girlfriend. Come to find out they broke up and I think he's really bothered by it. Poor guy got his heart broken... "Are you staring at my tits?" He pulls on my bikini top to expose my breast! I'm in shock, I can't believe my step-son just saw my tit!!! It seems to make him smile a bit, so I take off my top and show him my fantastic breasts! Seeing him happy makes me feel good.. Maybe he just needs someone to help him feel good too. I pull down my bottoms and start teasing his hard cock thru his shorts. Before he knows it, I'm sucking his throbbing hard cock. I let him face fuck me which puts him over the edge and he cums all over my face. "Don't tell your step-father, let's keep this our little secret!"
