She went back to her chaise and stretched out on her back and her black suit caressed her firm breast's as he said to me,Do you mind if I sit here sin...e there was a chaise next to me not being occupied.I said go for it. He pulled his t-shirt off and i thought Damn,this guy works out,then he removed his jogging pants to reveal a pair of sppedo's light blue,dark blue and a small section of white. He said to me,this is a swimsuit,which I agreed and then he said How do you like these,In a split. (in our family signs could save or missing one could brake you) My oldest sis looked at mom with a really you wont me to do what look. Then mom did it again. I grinned I knew the sign. I was going to see how far she was going to let this go. My hands were already under the blanket. So I slid the top of the nightie over my little sisters head. She just grinned at me as it came off. With out hesitation I played the game. I dropped the top at my feet. I knew even in. Neither of us has a partner right now so it's easy for us to have coffee klatches every Saturday morning. We have discussed sex but have decided that living next door to each other could cause future problems if we hooked up. We have spoken to each other about our previous sexcapades. One morning we were talking about sex stories. I told her that I not only read them but had tried my hand at writing one or two.She seemed very interested so against my better judgment I gave her the SOL web. She moaned with every stroke I made with the toy, her finger was playing with her ass and she was sucking on her other fingers, making little slurping noises. I watched as her sucked her fingers, licking up and down then sucking violently on her index finger. I went harder in fucking her pussy with the dildo. She moaned and tilted her head back, still sucking on her index finger. She took her finger out of her ass and sucked it to taste herself. I was now in shock that my best girl friend could.
