Our two slaves have to hold out their asses for us and we test which slave is the more fuckable. Which sizes of our strap-on fit in the ass cunts? How deep do our didlos go in? How much does the slave put on it? The one who is the more fuckable gets a blowjob as a reward - from the loser! One may cum, the other swallow!
