Unexpected Friendship at the Repair Shop

William..part 1. I am bi and worked with several men in a repair shop before covid. I would notice this new guy who was an older black man and he was slender but had good muscle tone and a great smile and very friendly. Not many of the guys would talk to him so I decided to make friends. Most of our guys were about 30 or less and this guy and I would the old ones in the group and I was 52 and William was 55. The group would sometimes have a few beers together but most would go home early to their wives and girlfriends but William and I would stay for a few more beers. He and I would talk about family life and I am single and he was married. He complained that his wife worked the evening shift at the hospital so they didn't see much of each other. Said he got lucky with his wife about once a week or every two weeks and that just wasn't enough. One evening I told him he could stop at my place for a beer and it was early so I knew he wouldn't be in a hurry to get home. At my place he had a beer and had to take a piss and he didn't close the bathroom door and I could see his ass and a shadow of his cock and I couldn't help but look. He came back and sat on the couch next to me and sat turned toward him and we were close. I got up and grabbed us more beer and sat closer looking at him and handed him the beer and purposely touched his hand. He didn't seem to mind so I laid my hand on his leg and told him he was handsome and it was a shame that he wasn't getting much at home. I was trying to seduce him but was not wanting to rush it just in case he wasn't into it. I could see he was starting to swell in his jeans and he leaned over and kissed me. I was shocked but excited and kissed him back and we made out for about 10 minutes and I lead him to the bedroom. He dropped his pants and took off his shirt and I was naked by the time he got on the bed. I started kissing him and worked my way down to his cock that was huge and hard. I could only get half of his cock in my mouth and was trying to give him the best head I could and he was really getting into it. He told me his wife never sucked for years and he loved getting head. He also said he had a 10 day load and he would cum quickly with a big load. I told him I didn't know if I could swallow a huge load and he whispered he wanted to fuck me. I went to the bathroom and cleaned myself out and took about 10 minutes. I came back and he was still fairly hard and leaking precum so I started giving him head again. He pushed me off and said he wanted to fuck me so I got the lube and put it on his big cock and my tight hole. He pushed me on my back and mounted me and continued kissing on me. I could feel his slippery cock rubbing on my balls and he found my hole and pushed gently while kissing me. I tried to loosen up and he was slowly entering me and it hurt a little. He continued to enter me and pushed a little harder with each stroke. I wanted it badly but it hurt and he was stretching me so much. I tried wrapping my legs around him and fucking him like a woman would but he was so big I couldn't escape the pain. I could fill him actually hitting my guts and he was all the way into my stomach. I told him I couldn't take it anymore and he backed out an inch or two but stayed in me. He was kissing me and telling me he wanted and needed to cum in me so I gently pushed against him but it was so big that I asked him how his wife could take it and he said she had a big loose pussy. I could understand why! He was twice my size.
