Yesterday my mother caught my teenage brother showing smooth beach stones up his butthole. They were on the beach together and she went to a nearby store to buy some ice cream, when she returned she come from behind him and saw that he was putting pebbles in his mouth to lubricate them and than putting his hand with a pebble in this swimming trunks and showing a pebble in his butthole. She told our dad and he is pissed and is trying to get an appointment with a psychiatrist for my brother in another town so that no one in our town finds out how perverted he is.
