I have been friends with this guy for 12 years. About 9 months into the friendship we slept together. He knew that I was still a virgin. We have remained friends over the years. About 5 years ago he was a long haul truck driver when I got the call that my Father was in a coma and was not expected to live. My Father lived 700 miles away and he happened to be home for Thanksgiving. he never hesitated, he made arrangements with the company that he was working for to take me to where my Father was at. I spend 10 days sleeping next to him in a tractor trailer truck. Nothing of a sexual nature happened but he did introduce me as his girlfriend on several occassions. A few weeks later he quit that job and came back home. He had a home of his own but his sons has damaged it but he could live in it. but he chose to move in with me and sleep on the couch. During the 3 weeks that he lived with me he would walk around in front of me in just his underwear. I assumed that we were a couple. But then something of a sexual nature happened one night and a few days later he backed off from me. I asked him about it and he said that he thought of me as "just a friend". Well we still remained "just friends". About a week ago he asked me if I wanted to give him a backrub, I said yes I can. He strips down to just his underwear. I rub his back for a while and then he rolls over for me to rub his chest. Well I didn't stop there I started to rub his cock. Neeless to say I gave him a blow job. This was the first time I had ever done that for him. He knows that I want more than friendship, and he is not the kind of guy to sleep around. What I am wondering is it just meaningless sex to him or does he really care for me and does he get scared after anything sexual happens between us? Every time anything of a sexual nature happens between us a few days later he backs off from me and acts like nothing happened.
