Mark lays on the hard stone bridge whilst Stacey sits on him, Emma films the action as both girls ignore poor Mark who is being sat on by Stacey, Mark is slowly being crushed under Stacey & struggles more & more to breathe as times goes on, Emma pans around & gets different camera angles & Stacey also shuffles around so she is sat on him a bit differently.
