Punch out

I love a straight clothed dude walking in on a naked dude like this.  He's so mad that he's willing to grab this little guy, even though he's completely naked, and put his hand on his shoulder (even if it's because he's going to punch him and needs to hold him still.)  He doesn't even care that this little guy's dick is right there in the open. 

Next step would be to throw him down and fuck his bare ass as punishment.
