Allright, down to the nitty-gritty. My 11 y/o (at the time) son snuck into 11 y/o SD's room at night and was putting his hand down his step-sister's pajamas which woke her up. She came and got us, I read him the riot act, and grilled him over and over if this has happened before. He said once before he touched her chest at night when we were overnight at a hotel out of town on a vacation, and he said he also briefly touched the outside of the pants in the private area of his 7 y/o 1/2 sister at his BMs mom's house when he was there to visit.
