“Yes,” Michelle said through her giggles. “It’s really good”. They looked at each other for another moment then without saying another word... Michelle turned the laptop around and as they picked up their wine glasses she hit play. They both watched as Rich climbed on top of Stacy, his hard cock disappearing between her closed thighs. The image of her half sister, face down on the bed, being fucked by Rich started to make her panties damp again. She looked out of the corner of her eye at Tina. I wont leave it till the last day.Two days later they were making love again in their sun room and as usual I was watching and masturbating.Half way through their lovemaking - between him having sex with her and cumming, they began to talk for ages and they both looked up at my room. I could se Jan was having a few words – I gathered he had told her. Then he looked up and waved to me to come down. I had no idea he knew I was there. I turned the light on and waved- I was on my way.Jan met me at. ”“Well I don’t think that will be necessary. I’m guessing she has been through enough.”“Well that’s good to hear, but there have been problems, and I want you to know that if there are problems, you simply have to make a phone call.”I heard the shower running.“What kind of problems?” I was concerned. I didn’t want to bring a serial killer into my home.“Well she was in a real bad situation and it seems that didn’t leave her when she got into foster care.”“What kinda problems?”“Lets just say. Fay had gone on to say that if she could get me interested in Kathy and he could get her interested in having sex with me we could swap. That would not be cheating.Kent said he liked that idea very much.Fay had unzipped his fly and taken his cock out. She had sucked it until they heard Kathy at the door. Kent had slipped away to the bath room so Kathy would not see his hard prick.The next day Kathy told Fay that Kent had began talking of how he would like to see Fay and myself having sex while.
