The two of them had been doing this ever since Deanna stopped attending church. Since she was now 30 and Summer was 29, that had been a long time now....However, this particular weekend, Deanna and Summer had both drunk enough Tom Collins and gotten sufficiently annoyed with their families to open up somewhat."Dee, honey, sometimes I think that we are so close that we should be lovers! Then again, I like men a lot and don't think that I could be faithful to you. I'm not even sure that I'm bi, for. It was one of the hottest sex shows I had ever seen and then they started to cry out in ecstasy as they jabbed each others pussies hard with their fingers, until finally they cried out loudly one last time and collapsed into each others arms.I was about to put my cock away and leave when one of the girls glanced my way and saw me standing there with my cock out watching them.I thought I was in really big trouble, but then she smiled and gestured me to join them, I hesitated for a moment and. NO WAY she told me, she said she knows thatkimmie and I have been doing more than justlooking or touching. My mouth dropped openand I remember getting beat red. She toldme that both her and s/i/s B have heard us in our room. But, she also said that she has seen kimmie giving me headin this tack room twice. OOPs, busted. Idid not know what to say or do. "A" told methat she would not tell on us for anyreason, IF.... IF what, was my questionto her. She said she has never given anyone. Alina hadbeen careful throughout the process not to let me get a glimpse of herwork. But she turned me round now to face the mirror. "What do youthink?," she asked, with just a touch of anxiety to match my own.I blinked, conscious of the heavy feel of my eyelids and the strangetaste on my lips. But as the image in the mirror came into focus, allthat was forgotten.For a brother and sister, Alina and I didn't look much alike. If yousquinted, you could see the resemblance. But where she was closer.
