My cock began to stiffen as I saw her talking to 5 or 6 boys about a half mile up the beach. She couldn't see me, naturally, which made my little peep...ng session all the hotter. It looked as if the boys were doing most of the talking while Sue seemed to be wearing a half smile. I noticed the boys behind her pointing and looking at her ass as one boy began rubbing his crotch. I couldn't imagine what they were all talking about, but I'm sure she was aware that they were all scoping her out pretty. When she got up, the mistress of the house then lay on top of me and started kissing my face, my lips, my neck, and even my chest. I could tell then what kind of woman she really was, an extremely passionate one, given to just yielding to her urges whenever she could get away with it. She clearly didn't like being restrained from acting on her desires if she had them."Can you keep a secret?" she whispered, as she pressed her smooth skin against my rougher hide."Sure, I guess, but only if you. On your doorstep are Stacy Smith and Gwen Doe, both wearing long coats."Hi John," says Gwen cheerfully, giving you a kiss on the cheek and squeezing past you through the door."Happy Birthday," says Stacy. "Sorry we're late. We were almost here but then we decided we weren't dressed slutty enough, so we went back to change!"Stacy gives you a hug and a kiss, and you offer to take her coat. Underneath she's wearing tight black lycra hotpants over the top of black fishnet stockings and high heels.. They both got ready ,while we ready the camera and mom was watching and helping me and dad.After few mins, I narrated the scene which is a normal couple sex,including a ass fuck for the first time and a creampie and said to start the scene..Camera rolled on,while uncle was in the room,aunt opened the door and entered and sat near to him on the bed.Now they both liplocked for few mins and aunt removed his shirt button one by one and he removed his shirt and aunt licked his nipple for few mins.
