1.
When having sex with a girl in the missionary position on the bottom bunk of a bunk bed, hook your hands and feet into the cross bars of the mattress above you so that the only part of you touching her is your cock in her vagina.
Yeah man, she was sleeping so I had to pull a missionary impossible to keep her from waking up.
