Swap Roles

John and Emily pulled up to the start line, though really it was all Emily. John was just a passenger princess. There were a lot of murmurs as the other pairs started at them.

“Is that allowed…”

“Huh, feel kinda bad for that guy…”

“He’s not sitting down for a while…”

John grimaced and tried to ignore them, as well as the tip of the massive strap-on that Emily had **** into his ass.

“Oh shut up, look at him I wouldn’t stand a chance if it was the other way around. And yes it’s completely legal and follows the rules. And John quick moving around.”

John and Emily had swapped roles, he would be the “steerer” and Emily would be the “thruster”, though there really wasn’t much he was doing. Emily had pulled out a few strap ons and picked the longest one so she could get maximum thrust capability. Unfortunately it also was by far the thickest, and so she spent most of their preparation squeezing it into John’s behind to get him prepared. She also had tied some rope around the handlebars of the bike for each hand so that she could steer even though she was the thruster. John had no job other than to sit there and try not to ejaculate for the time penalty, which would be an impossible task, except Emily had accounted for that as well. She bought a chastity cage from the Game Master using some of the points from round 1 and stuffed his cock inside. She actually had to buy 2 because the first one was too big and loose on him, which led Emily to curse John and his small dick for a couple minutes before she finally snapped it on. The cage not only lock up his cock but also crushed it flat against his body, as well as blocking his urethra with a sounding rod. Finally the cage also wrapped around his balls and pressed down on his sperm tubes. With this setup Emily was in complete control, and John wouldn’t be able to ejaculate. All he had to do was sit there and take the inevitably brutal pegging session.

“How you feeling? Fine? Good boy.”

Emily slapped his ass sharply and slowly pulled out so just the very tip of the strap-on was in his ass.

The Game Master appeared in a burst of confetti in front of everyone.

“I see everyone is present and ready! Remember, anything goes, you can interfere with other bikes, though we’ll step in if things go too far.”

She glanced around one last time before waving the flag.

“Ready, set, GO!”
