Wet Paint (M/M Watersports)

When Elliot took a nude modeling job for temperamental artist Ivan, he thought he knew what he was in for. But when Ivan refuses Elliot a needed bathroom break during a session, the ensuing accident turns out to be hot. So hot that Elliot comes ready to the modeling session the next week with a full bladder, eager for more! Warning: this 4800 word story contains M/M desperation, accidental and deliberate wetting, a piss hard-on, a handjob, and very full bladder sex; adults only!

Excerpt:
My need was now so great that I could barely keep from holding myself. “Can I please use the restroom?”

“You promised me an hour. It’s only been half.”

“I know, but I can’t.” I sounded so young, so helpless. “Give me two minutes.”

He was unmoved, barely even looked at me. “I can’t either, Elliot, the light and angle right now are perfect.”

I wanted to walk away, but I needed this job even more than I needed to piss. But then Ivan said the most provocative thing: “I’d rather you piss there if you’ve got to.”

I practically choked. “What?”

“Piss there. It’s a stone floor.” He raised his eyebrows at me over his drawing pad. “I’d personally clean up your puddle if you did me this favor.”

I should’ve told him he was insane, but…some part of me perversely liked the suggestion.
