The mating call of a rare bird that inhabits the car engine. Identified by a loud screeching sound upon ignition (not to be confused by a worn out engine belt)

triple piston

When a man, nude, between two females, as he is fingering both of them, one of them has a hand on his balls and the other is jerking his penis vigorously until they all get off.
