"Just come in and have a sit," she said, pointing to the sofa. My and I walked into the living room and sat down together. Robert was sitting right ne...xt to my wife. They had the lights down low and some kind of rock music blaring on a DV player. As my eyes adjusted to the dim light, I could see that there was already a lot going on. Some couples were kissing and fondling. Over in the corner I saw two big breasted women locked in a deep kiss as they sat on a chair. They were both completely. There she was her 36c chest and nice perky ass and in she went.As she began swimming around, she couldn’t believe how good she felt. Her body felt strange, but she couldn’t quit describe it. She noticed a tingling feeling in her nipples and pussy but thinking it was because she was swimming naked seemed to answer her thoughts. Eying the float she began to slowly swim toward it. She was feeling very relaxed as she swam and when she got to the float, Beth held herself up with her arms on the. . perhaps because I didn't want to see it. But once I did notice, she was all I could think about. All through high school, the only girl I dreamed about, the only girl I ever jerked off too was my older sister. By the time I got to college, well... I was pretty much obsessed with her, my obsession having a very negative impact on my social life, my few friends distancing themselves from me as my fascination with my older sister deepened into a near mania.Melanie was five years older than I. But she did not get her luck, she even used tell me when we have sex she is missing her brother and also said that she used to enjoy more when we both fucked her together for which I told her to don’t spoil the reputation outside family, with you or my brother it is fine but not with outsiders.We used to have general chat, once we were about to have sex, she had mentioned since her brother is newly married her parents coming to the city, I just said in joking why can’t you ask your father to.
