i went on a trip with like 30 other guys and we all got to sleep in our own dorm rooms with showers and everything and part way through the trip one of my friends asks me if i jack off and then when i say yes he pulls out his cock and tells me to take mine out and we masturbated together and we did this probably 4 times a day for the rest of the trip is was amazing that is my only masturbation with someone in the same room experience
