Over thanksgiving break was home visiting my mom and stepdad. They've been married for just over four years and in the last year or so I've clearly sensed him being more affectionate with me. He's 48 and works out. On thanksgiving eve, Mom was at work, but he had the day off so he offered to take me to his gym. It was very cool working out together. His gym is really nice and I noticed a number of attractive women and men but I was one of the younger people there it being the middle of the day. I think he was showing off by working out extra hard. He commented on my body and felt me up several times. I did the same to him. When we walked into the steam sauna, it seemed that we may have interrupted something going on between two guys. Neither of us said anything until they left then I noticed mike discreetly stroking his cock underneath his towel. I instantly got hard but didn't do anything. His eyes were closed. Then I felt his thigh press against mine. I didn't move my thigh. I closed my eyes and leaned back. After a minute or so his thigh moved away and then I felt the back of his hand against my thigh. Again I didn't move my thigh. He slowly began moving the back of his hand against my thigh. I moved my thigh against his hand and then felt him turn his hand over and he began to slowly squeeze and stroke my thigh. I then pulled my leg up and rested my foot on the bench with my leg against my chest. He quickly pulled his hand away. I kept my eyes closed and opened my legs a little, After a few moments, I felt his hand again this time taking advantage of my towel being pulled up by my leg exposing my hard cock and balls. He gently felt my hard cock and balls. I was leaking precum at this point and he used it to massage my head. I moaned a little and scooted down to give him better access. Then his fingers left my cock and started to massage my smooth balls which turns me on more. Then his fingers moved below my balls to my smooth pucker. When they grazed over my hole I moaned "oh, fuck." Right then the door opened and as a guy walked in I quickly moved my leg down and mike moved his hand away. After a few seconds mike got up and said he needed to cool down. I was still hard and checked out the guy who had walked in. He seemed older than my stepdad but he, too, had a really nice build and especially great pecs. He nodded at me and I nodded back. The steam started back up in earnest, and as it did, I noticed the guy open his towel and his large cut cock began growing thicker and longer. He caught me noticing his display and smiled. I nodded again and watched as he started openly stroking his large cock. The steam was getting pretty thick at this point and I was thinking of leaving to catch up with mike. I stood up and the guy kept looking at me while stroking his now fully hard impressive erection. I went to the door and wiped the condensation away to see if I could see mike. I didn't see anyone out there so turned back to the older guy and walked up to him. I reached down to take a hold of his large cock and he put his head back and moaned. I couldn't resist. I knelt down quickly and took his cock down my throat. He put his hand behind my head and told me to suck him. I started sucking his big cock, and he started fucking up into my throat. After a few more strokes I heard him start to grunt and my mouth was flooded with a huge load of cum. I swallowed what I could but he kept shooting holding my head down on his cock. When he finished, he said thanks and we both got up to head to the showers. As we stepped out of the steam room, mike was right there getting ready to come back in. I told him I needed to cool down and he said, "I bet you do" and winked at me, I must have looked startled not sure if he saw his "straight" jock stepson just give a blow job. I told him I was heading to the showers and he said he'd be there in a little while patting my ass as he walked by. I'll tell more about what happened with my stepdad later.
