My little bro was visiting my college apartment and I was running late to a class and we had to hurry because he was sittin in on the class. I was getting dressed in one room and him in another. We made it to the class ok and then after the class we went back to my apartment and we started to watch some tv. We decided to watch a movie he brought over he reaced over the side I the sofa and his shirt raised up and I saw he was wearing my panties. Should I tell him or se how long it takes for him to realize?
