Many years ago when I was in Niagra Falls, I went for a two hr massage in a nice professional massage centre. Turned out to be a fit young guy. Everything was undraped and his massage was spectacular. On several occasions while he was moving around I was sure he was purposely brushing his dick against my arm, or any other reachable body part.
During my second half of the massage while I was on my back, his touches seemed to be more intense and I could feel the thickness of his cock whenever he made his moves towards me.
I just lay back, closed my eyes and let things carry on. Once when he brushed against my hand I made a subtle move to get a better feel. Things progressed from there as his focus on my upper thighs included several forearm pressures against my bare cock. I was starting to get a chubby and he poured some oil around my cock and the oil leaked down the crack of my ass.
His hands ran down the inside of my thighs and ever so slowly I could feel him get closer to my ass as his fingers ran between my cheeks.
I was hard and twitching by now and when I felt something warm slip around my cock I opened my eyes to see the head of my cock in his mouth.
From there I totally relaxed, enjoying the unexpected pleasure of a Bj with prostate stimulation until I had an explosive orgasm.
So BFK, let things go as they go, you may be a very happy man when it's all over and done
