Last Stop at Albuquerque 

While having anal sex with a girl, you stick your thumb and index(ring finger too if you're feeling particularly squirrelly) into her vagina and use them to jerk yourself off through her vaginal wall usually resulting in climax hence the term "last stop".

So I was doing this chick in the butt and I decided to finish myself off with a little last stop at Albuquerque action.
