A couple sits on a futon in a slouched position, wearing motorcycle helmets. the male on bottom in a seated position, the female on top but on her knees as if riding a crotch rocket. The female must also twist the males nipple while performing intercourse while he makes motorcycle noises. As they near climax, they both must begin headbutt each other until the weaker party is unconscious. The consious party then deficates in the others helmet and seals the facemask shut with duct tape.
Josh: Hey guys, why does my motorcyle helmet stink so bad?
John and Abby: I don't know...we didn't use it for our motorcycle futon fuck.
