Time to get a look

Josh quickly heads to his room. He locks the door behind him and stands in front of his mirror. He pulls downs his pants and underwear and finally sees what he got.

First thing Josh learns is that he's got to thrust his crotch forward to actually get a good look. Definitely different from a dick.

He examines the outside, the lips are slightly wet, probably from the excitement and the taboo nature of his actions.

Then he spreads the lips apart. Weird is the only thing he could think of to describe the moist hole.

He tries to slide a finger in. His breath quickens as he feels his finger push in and go deeper. He gasps as he bends his finger. The strange sensitive walls feel good from the pressure. He slowly rubs the insides trying to wrap his mind around the feeling.

He then realizes he is already masturbating in less than 5 min and stops. He might be a pervert that steals his sister's pussy, but he can have a bit of self control right?
