I like to lay on my bed totally naked when my sister's friends come over the house. When they come upstairs, they have to pass my bedroom to get to my sister's bedroom. Of course my bedroom door is open. I alway lay on my side with my bare ass facing the doorway to my bedroom. Sometimes one of the girls walk over to me and look at my front side to get a look at my full erection of 5 inches. I don't know if they laugh just because they see my dick or if my erection is only 5 inches.
