Your warm pussy felt so good wrapping around my hard cock. You go all the way down and grind again. You moan a little and squeeze me tight as you lift...just a little then back down hard. I can tell you cum just a small bit, but your hold back. You lean forward a little bracing on your knees and you start jockey riding me. You move faster and start to swirl as you go up n down. You look between your legs and see my cock going exactly where you want it in your pussy. You keep watching and moving. "Oh, fuck!" I thought to myself, "I will never pass my exam now!" I walked over to him, trying to keep my cool, Dallas looked up and said"Um Hi, are you the one I’m tutoring?" Yeah" was all I managed to say. I sat down and noticed that he was extremely muscular. I felt my thong getting damp. "Mother fucker! I can’t be horny now!" I thought to myself. I tried to block everything sexual out of my mind, and get this session over with. Dallas started rubbing his neck; I asked him what was. Not that it takes much to keep a 15-year-old boy's motor running.Showered and refreshed, I entered my bedroom with a towel wrapped around me, dropping it as I closed the door. A small sound made me quickly look up and realize that Kit was sitting on my bed, with eyes as big as dinner plates. I quickly turned red, grabbed the towel and blustered, "Kit, what the HELL are you doing in here? You know better..."Kit was even redder than I was and stumbled all over herself apologizing. "I'm SO sorry,. I am married, with k**s, and my wife has no idea that I am on this site every day. Now my disclosures are out of the way, here is my story.I met this woman, “L”, on Craigslist through her husband. One of my biggest fantasies is to be with a woman in a MFM situation or with her husband watching. I would love to watch my wife with another man, but she is not into this type of activity. So, I posted on CL what I was interested in and her husband, “C”, e-mails and we go back and forth on.
