Over the past couple of years I made friends with a straight guy at work. First it was coffee breaks together then it was going on outings sometimes with his wife more often not. He is the type of guy who is very personable and easy to talk about things intimate and what ever is on your mind. I told him I was gay which didnt bother him at all.He said he was totally straight. Over the years I fantasized what it would be like to have sex with him but I feared if I make a pass at him it might ruin our friendship. I shared on occasion hotel rooms with him when we were at work conventions. Seeing him without clothes off only fed my fantasies. Lets say hes built and very hung. Recently approx 500 people were let go from our company including both of us. We got our notices on a Friday and I stopped by his place in the evening to talk about all the happenings at work.His wife was away at her mothers for the weekend. He was emotionally upset so I rubbed his neck and shoulder to release some of his stress. I realized that to go any further might overstep boundaries of our friendship. Before I knew it he hugged me and then started to kiss me. I pulled away but he said it was ok.It seemed after that I willingly gave in and let whatever he wanted to do happen. Clothes started coming off. He pushed my head to his very large penis. Before I knew it he was leading me to the bedroom and everything became more intimate. He slipped on a condom and said he wanted me to show him what making love to a man was all about. I was glad he had a good supply of KY in his side table. He patiently mounted me. The love making was intense. Ive never felt such intense intimacy during sex with anyone else.I stayed the night and we made love until the sun came up. We kissed as I departed. The following day he called and said while it was a great and hot experience both physically and emotionally he felt it shouldnt happen again. We agreed to be friends and nothing more. Now since that time my body craves for him. Ive noticed that its a bit more difficult for him to share whats happening in his life even though we still do most of the same other stuff together. He once admitted that it would be very easy to go to bed again with me but he wasnt sure it was right. He is unhappy in his marriage but says other than our one time , he is still straight. I cant get him sexually out of my mind. I masturbate continually reliving the sex we had. He is now separated from his wife and they are planning to divorce.There are no children. Sometimes I wonder if he has thoughts of making love again? I noticed he had a picture of me on his dresser along with those of family. I see him looking into my eyes longer than normal. Im not sure where things are at. Im burning with desire to make love with him over and over.One time he hugs me then he pulls back. It seems as though he wants more but then there is hesitation. I dont know whether I should push it any further or what to do? Has something similar ever happened to you?
