My first fully erotic massage happened a couple of years ago. (Full disclosure I'm only recently out). I found him on RM a couple towns over. Eastern European bodybuilder who was more handsome in person than his pictures. Arrived at his condo where the table was in living room. He stepped away while I stripped down and lay face down on the table, with no draping. He came in and began a solid therapeutic massage, spending a lot of time on my neck and shoulders. During some long strokes from my shoulders down to my ass I realized he was shirtless, I figured it must have disappeared while he was out of the room. He continued on to my side and I felt his bulge pressed up against my hand. Not knowing the protocol, I gently rubbed it and he kept it in place. Eventually he moved down and started working my legs, and as he did so I heard the shorts being removed.
Still a very solid therapeutic massage, he reached my thighs and glutes. I felt my cheeks spread apart as part of the massage and then he moved my legs apart and knelt between them on the table. More massage of my inner thighs and hips, with his hand beginning to brush my taint and balls. I felt my cock begin to grow and he found that too. Suddenly, my cheeks were spread and I felt him blow on my hole and then ever so lightly he probed with his tongue, before tasting me deeply. Then he pulled my cock down and pulled it into his mouth briefly, so warm and wet.
Then he flipped me over and started to work on my front. At some point he was in the right position and I turned my head and took his cock into my mouth, where it went from semi to solid and within a few minutes he was fucking my mouth and then feeding me. I had no intentions of going that far but got caught up in the moment.
He finished the massage with a excellent happy ending using both hands and mouth. I was incredibly relaxed and my body felt amazing.
I saw him a couple more times. The first time I saw him after I came out he told me he was proud of me and we started making out midway through the massage. We ended up in his bed, where he threw one leg over his shoulder and fucked me while he jerked me off. We both collapsed spent.
