You see, when I first met Amy, Jill's husband Ron was on a company posting in Singapore. Ron works for some bank in the city and they had sent him out...there for a few years. Apparently he was in for a big promotion when he returned. Jillian had gone with him, of course, so when I met Amy and fell in love with her, I had no idea how close the two sisters actually were.I knew that just after I had met Amy she had gone out to Singapore to visit her sister for a month or so and when she came back. Monica freaked and asked me to call my wife back. At this point, I felt comfortable enough to joke with her a little. I called my wife and acted like she was upset with Monica hanging up on her. Monica cringed as I handed her the phone to talk to my wife. When she took the phone my wife was laughing hysterically.We finished eating and Monica offered to pay. I joked that if she paid, I'd be obligated to sleep with her. This was the first time I had see Monica blush. I paid for lunch and we. .. he smiled, stroking my head and said "swallow". I took my tongue in, closed my mouth and swallowed a lot of cum... loads.He stood and watched me for a while. I was totally disgusted, and then... he took out his cock again, now all soft, and pointed it at me. I kinda knew what was coming, so I clenched, scrunched up my face and closed my eyes. I remember thinking that I couldnt believe this was happening... it was like something from a porn film. He stood there like he was standing at a. Our kissing became more passionate. "Fuck me, now, here on the floor," she whispered. She had never liked me to use the f-word and always resisted me fucking her anywhere but on the bed. We sat up on the floor. I started to get up to get a condom (we used them, very successfully, for birth control) but she said, "No, fuck me now. Fuck me, you horny stud. I want your naked and hot cock in me now." She was almost shouting, but in the hungry sexual way of a woman overheated by sexual lust. She was.
