mostly showing off

I am a middle age guy (44). Not entirely gay, but, more Bi. I am also very good at home repairs etc. A few years ago I answered a ad from a older gentleman who was in need of someone to install a laminate floor in his upstairs room of his home. The room was a workroom & quite large. Having experience in that, He had all the material. I agreed to do it. His wife was not well & confined to a wheel chair downstairs. Being the middle of a really hot summer, I showed up wearing only shorts & a T-shirt. He explained to me what had to be done & left me alone. Being extremely hot I removed my T-shirt & had only the shorts on & shoes on. He appeared again & commented on me wearing only shorts. I explained it was hot up on the second floor & hoped he did not mind. On the contrary, he replied & complimented me on my nice physique. He then said, feel free to remove the shorts, too if I wanted to.. I took him up on it & removed the shorts, too, leaving me with only a very skimpy thong that barely covered my genitals & left my butt bare except for the tiny strip between my ass cheeks. He commented "now that's more like it" & left. I continued to do the floor. It required me to be on my knees, but, I had knee pads on, except for the thong. He showed up again with some lemonade for me & suggested I take a break. We chatted for a bit. Then, he commented that the thong must be uncomfortable with that strip between my ass cheeks & that he was ok if I wanted to remove that too. I did not hesitate being a exhibitionist & removed the thong leaving me completely naked except for the knee pads & running shoes. I dropped to my knees & resumed installing the floor again. I made a point of spreading my legs wide to reveal my butt hole & my hanging cock & balls. He stood over me watching me for a while. Then I felt his hand on my butt ever so lightly. I paid no attention to it & continued to work. I'm guessing it gave him the ok. He then began to feel my but more intensely & I felt a finger go into my butt hole. I stopped working, but stayed on my hands & knees & gave out a little squeal, I guess. He then reached under me & began handling my cock & balls I became extremely aroused & began to moan. He stood & zipped down his fly & took out the biggest cock I have ever seen & said, "feel free to put it in your mouth" which I eagerly did. As I sucked him off, I masturbated myself. I believe we both ejaculated together. His was like a gusher. I swallowed much of it, but still got some on my face & chest. The job took me 4 days to do. Needless to say, every day was like the first day. I believe, the last we did that twice. He never performs oral on me. Only plays with me & fingers my butt hole. I'm fine with it & can't wait to suck him. I've become like his handyman & still go there & do chores for him. We have become good friends.
