Tom

You see your brother Tom in the bathroom. He has the water running, in an attempt to cover up the fact that he's masturbating. His cock isn't anything special, but his body is lean and trim, and he's been shaving his body hair. He's always been the 'dream' guy for a lot of girls, but you figured out pretty quick he didnt lean that way when he never gave them the time of day.

Surprisingly, Tom doesn't really have the best masturbation technique. He's just sorta rubbing it back and forth. No lube, no strong grip, nothing. You wonder if someone hasn't been jerking him off his whole life. It certainly wasn't you. He seems frustrated after a few minutes of jerking off, and he gives up.

However, you are hard, and wonder if your brother wouldn't mind a few pointers.
