Right at the start of Braxton's introductory solo, he mentions he's not shy and likes to show off. Had he not mentioned that, you would have been able to figure it out from how comfortable he clearly is in front of the camera. But, I guess when you're that handsome and horny it's inevitable you'd be a natural in front of the camera!
Braxton's first sexual experience, with an older girl, was quite the wild one! So, I guess it was inevitable he'd be a very open and adventurous guy, willing and eager to strip down on camera and jerk off. He likes having sex in public places and has had a host of experiences doing just that.
Taking things to a whole new level of showing off, Braxton strips down and strokes off for all of us here!
