Having awesome bouncy sex on the surface of a trampoline. Then as the humping grows in intensity the girls vagina experiences rapid pain because the penis cannot stop bc the motion of the trampoline keeps him going.
Maria and Keith had trampoline sex and Maria could not handle the pain but Keith could not stop driving his penis into her.
