When a pornstar is unable to handle a large cock, especially when the guy is thrusting too deep in doggy position, she/he starts to move away on her hands and knees, this is known as 'running'.
The blonde couldn't take the deeply thrusting huge nigger cock any more, and started to inch forward, yelling, and the director muttered 'she's running' but the huge black man carried on relentlessly ramming her with his BBC until she collapsed in a whimpering, fetal heap.
