Just wanted to note that the pumpingmuscle series was filmed over 10 years ago. A lot of those guys either moved away from fitness careers, with a small number of them becoming professional bodybuilders. Don't remember this guys name. I follow the bodybuilding community regularly and I've never seen this guy come up within the last few years so idk, he may have retired from all this
 
He filmed a few viids with the pumping muscle predator. IYKYK. Don’t remember the model’s name but he let the videographer explore his body a lot. Rubbing his hole and taint a ton in one vid. He finally showed dick on the last vid and unlike a lot of the models who either were very uncomfortable and/or definitely not into it, he had to wedge his dick into one of his thighs because he kept getting hard. Kept trying to hide the fact but it was so obvious and hot af. Might be an exhibitionist who gets rock hard getting nude? Might be gay/bi? Maybe both?
Wish I still had the frontal vid.
