Catching Straight Zack Stroking

Straight roommate Zack comes home from a night out with the guys and pops in a porn video. As he gets naked, so I grab the camera and start filming. He strokes his stiffening dick with both hands and soon it's hard. The phone rings (it's probably his girlfriend looking for him) just as he shoots a huge load on his chest. I follow him to the bathroom and watch, as he cleans up. His cock is still rock hard!
