A lone boy in his bathroom ..the door was left open allowing you to watch what he is up to! He does not know you are looking in..!
And he soon gets his tackle, wet, erect, masturbating, and then cums, standing, leaning on sink, with his penis pressed agains his belly, getting extra wet as result also..with sperm glistening on his smooth body and thighs!
You should not be watching him!
