Only technically my brother.

Matthew could not understand how his brother James could keep his hands off his new young female body with its perfect pair of tits hanging from his chest and the sweet pussy between his legs.

That caused him to have a hard-on every morning when he saw him in his underwear coming down for breakfast to there parents annoyance.

He knew it was wrong to spy on his brother James whilst he got changed but he just could not help himself.

As he once again hid in the closet watching his brother take off his clothes whilst he frantically played with himself and justified his actions to himself in the knowledge that it was not his brother's body he was actually masturbating over.
