I walked back into the bedroom. I looked at her. All of a sudden she looked like a really young woman like my daughter who was only 20 years of age in...tead of some fully grown woman that had been dancing around in my head I thought. I shook my head and told her “I’ll admit this” and looked at her in her adorable blue corset. I stared at all of her. “Despite how old you are I’ll admit that you’re one hot and foxy young woman. Do something for me, okay?” She asked what. “You are as pretty as they. I clamped my legs around her waist. We kissed while she carried me to her bedroom. She threw me on her bed and sat on top of me. She grabbed my hands and puts them over my head. Her beautiful face hovering above mine. Just a few seconds of eye contact before she kisses me again. I want to touch her, but I can’t get free out of her grip. I want to kiss her even more, but her lips are leaving mine. Her body is wiggling upwards until her nicely shaved pussy is pressing onto my mouth. It’s my turn. At this point I was still wearing my camisole top and French knickers, by now my cock was fully erect so wearing French knickers made my hard on comfortable and snugly unbounded. David lifted up my camisole top and caressed my nipples, he sucked on them until both teats were erect just like a cherries David said "I going to fill your cunt with my spunk and make to pregnant", which was a turn on for me, David then gyrated himself while he straddled on top of me, by now David's cock was. The room became illuminated in bright light. My immediate thought was “my wife has come home”. I watched in horror as the door fully opened and, as if in slow motion I saw, not my wife, but my wife’s older sister poke her head inside. I could only stare at her as her expression changed from mildly curious to bad surprise and then just pure raw horror.The sight that greeted her was one of confusion and naked bodies. The bed covers had long been kicked off so we were fully exposed when that light.
