Jono let me hear the recording of Pictures at an Exhibition on his iPod. I had a huge orchgasm during "The Great Gate of Kiev"

An orgasm that occurs when two people are forced to drive off to the middle of an orchard to have sex because their parents wouldn't leave the house.
My Dad doesn't let Pete hang out in my room with the door closed so we parked out past 120 and gave each other orchgasms.
