SP's are like olympic champs of sex..we can run circles around you guys
In honour of the winter Olympics coming to Vancouver, VV should offer an Olympic Sex Challenge.
You pay her 1hr PSE rate, but as soon as you cum you have to leave. Five minutes in the door, 30 minutes. Don't matter. But you get to stay for as long as you can last. One hour, two hours, whatever(*).

That means active fucking, not just laying around sucking on her toes or leisurely tonguing her anus(*!*). If she's nice about it, she'd offer you a two minute break after every one of her orgasms(***).
I'd take that challenge. What the hell, I've lost more money quicker.
What do you say VV, I'm in town this October.
Footnotes...
(*)if fuckfest last longer than four hours VV's tip must be donated to a carity.
(*!*)10 minutes of anus tonguing should be allowed for every hour of sex.
(***)squirting orgasms earn a four minute break.
