John’s fairly average

“Hmm, around 5-6 inches? Definitely not the biggest we’ve got around but it’s not that small.”

John heard the Game Master tap her foot and hum as she thought.

“Alright I’ve decided, here’s a new set of rules just for you! Emily, after every orgasm John has you must give him a 5 minute rest period. Ah ah ah, no objections! Since John just came you gotta give him 5 minutes after I start the clock again. AND John, you only have to make Emily orgasm once.”

“What, isn’t that a little unfair?” Emily complained. John had to agree, it felt a little bit unfair and he wasn’t sure if he liked the insinuation that he was too incompetent to pleasure Emily, but he wasn’t going to say no to the advantage.

“Emily, you of all people should know your limits, and that limit is quite far. You’ve just gotta last 10 minutes +the time it takes to make John cum twice, and right now you’re up against an amateur. Anyways, that’s my final ruling. Any questions?”

John and Emily shook their heads.

“Well then, John, try not to lose too fast and give Emily a good time alright? Read, set, go!”

She disappeared in a cloud of smoke and the time started again.

“Well then, let’s see what you got John. Try to at least figure out where my clit is before your first 5 minutes are up.”
