There's just something about his shoes. :) I'm not a foot fetish guy and I'm not sexually aroused by footwear. Personally, when I'm at home, I take my shoes off at the door and walk around in my socks. It's just more comfortable. So when I see this boy holed up in his bathroom, stripped down and showing off a naturally toned smooth body, and I see a pair of shoes kicked off in the corner along with a book bag, I imagine a horny teen just home from school who headed straight to the bathroom for privacy and a heated stroke session on camera. :x Judging by the thick creaminess of the load, I bet it felt good too.
