Midnight Bobsled
When you are banging a chick from precariously positioned at the top of a flight of stairs, and just as you reach climax, you give her a nudge forward and ride her down the steps while inside her. The ensuing vibrations feel.... just terrific.
So it was really hard to trick Jane into me preforming a midnight bobsled on her, because who the fuck has sex by the top of the stairs. I told her to trust me and she fell for it. I came buckets.
