A masturbation maneuver in which a nude male, isolated in a bathroom, jerks off standing up with his feet shoulder-width apart until ejaculation, at which point, while continuing to stroke himself with his cock pointed downwards, he suddenly squats so his thighs are parallel to the floor and bounces slightly at the knees until ejaculation. The pleasurable pain provided by the stretching of the leg muscles endured during orgasm is essential for a successful Cream Trampoline.
Bob hurt his back doing the Cream Trampoline last night.
