Winchester Arm
In the act of an Eiffle Tower (chinese finger trap)(Tagging a bitch) the man entering from behind uses his arm to bob the bitches' head up and down on his co-pilot's fighter stick. This action is continued until ejacuation is achieved all the while maintaing pelvic thurst into either anal or vagina of the female conterpart.
Jimmy went to the party expecting a Cleveland Steamer or a Alaskian Pipeline but was pleasantly surpised when he and his pal Nathan successful performed the Winchester Arm with the aid of Nathan's girlfriend.
