Stepbro Teases Me Into Trouble in a Sticky Encounter

man I gotta tell you about this stepbro thing that happened with my wife and her stepbro last weekend he came over to help with some furniture and the whole time he was eyeing her tits in that thin tank top and I caught her giving him this look back so I said why dont you show him what a good cowgirl you are and she straddled him right on the couch I could see his big cock pressing against her jeans as she ground down slow and teasing she leaned forward and whispered something that made him groan while she worked his fly open and stroked him to full stiffness then she slid her panties aside and sank onto him inch by inch we all watched her ride him till she came hard clenching around him and he pulled out just in time to paint her face with a load while I filled her from behind after creampie and facial she kissed us both with that sticky smile
