Midori poked her head into her apartment. As she had expected, her roommate was out, probably with her boyfriend. Charles followed her in as she went into her room to change.
"Don't pee here," she called to him as he sat in the living room. "You'll need a full bladder for our game."
Midori walked out of her room naked and smiled at Charles on her way to the bathroom.
"I'll get something to drink, I guess." Charles stood, watching his girlfriend go into the bathroom and hearing her start the shower.
"Let's dig in." Charles had taken Midori to a Japanese restaurant for lunch. Charles had been drinking water while at her apartment, and he was feeling somewhat full. Midori had had a few glasses before they left, so she felt much the same. "So, what are your plans for the weekend?"
"I'm spending the weekend with you," Midori said. "Also, I was hoping we could...well, move in together. See, Melanie's new boyfriend has decided to move in with her, so I'll be leaving soon. It doesn't have to be any time soon, just before mid October."
"That's perfect timing. Mike's planning to move out soon, so I was about to see if you wanted to be my roommate."
"The roommate you can fuck every now and then," Midori purred. "To love, life, and things we like! Kanpai!"
The two clinked their sake glasses and drank. Midori squirmed a little as she drank, feeling the pressure in her bladder. Charles noticed, but said nothing, knowing it was part of the game.
"All right, I'll pay the bill and we can go," Charles said. "Um, you are okay, right?"
"Of course I am." Midori gave Charles a smile as she crossed her legs.
"You look like..." Charles leaned in. "You look like you might burst soon."
"Yeah." Midori smiled. "You know nothing of my skill. I'm going to hold it, and so are you." Midori pressed on Charles's bladder under the table. "Pay for the meal and we'll go to the park."
"What's this game?" Charles was gently fidgeting while Midori simply sat with crossed legs.
"It's just our good fortune that no one's in the park on a balmy Saturday afternoon." Midori gently pressed on Charles's bladder. "The game is that we sit here and hold our pee. The winner decides the penalty for whoever pees first. No grabbing yourself, and no bladder pressing. Only leg crossing and movement, got it?"
"Got it." Charles sat and crossed his legs. "I can hold for a while, and I'm pretty sure women don't hold quite so well."
"Like I said, you don't know my skill." Midori crossed her legs. "I can hold with the best."
The two of them sat where they were for a few minutes. Charles began to fidget a little while Midori remained calm. Charles realized that Midori was deceiving him in the restaurant and she could probably hold for longer than he ever could. Determined to win, he sat there, doing everything he could to ignore the dripping noise his girlfriend kept making.
"I've always gotten off holding," Midori recalled. "I discovered my fetish shortly after I started masturbating, like I told you. Between our parts, I've always thought peeing with a pussy is more fun. Dicks can be aimed more easily, but my lack of a hose means I can have more improvised fun."
"Please...don't talk about it," Charles managed. He was on his feet walking around with bouncy steps. Midori enjoyed watching her boyfriend's ass as he fought his bladder.
"Oh, does that put you on edge?" Midori stood and bounced, mocking Charles. "Of course, even when I'm not jilling it, I like holding my piss. I'll hold it in for as long as I can, then watch it shoot out with lots of force. It's so satisfying." She leaned in to his ear. "Sometimes, I can angle my stream so it hits my clit and I can cum as I'm pissing. It's amazing. Too bad your anatomy doesn't allow that."
"Stop, stop, stop." Charles continued dancing around. He could feel his resolve dissolving.
"Am I making it hard for you? Does me talking about peeing make you have to go? Just harden yourself, you big stud."
"Fuck!" Charles doubled over, grabbing his penis.
"Ah, ah, what did I say about grabbing yourself?" Midori smiled.
"It'll come out if I don't."
"Let go of yourself, Charles."
"Fuck it, I concede."
"Not bad. You lasted longer than I thought. Okay, go pee on that tree, and I want it to be the best piss you've ever taken."
"Midori, I don't..."
"No one's here and I know you don't want wet pants." Midori pressed on Charles's bladder. "I'm sure that sake and ramune are catching up to you. And you know you shouldn't hold it in. Now get rid of it."
Charles went to the tree Midori designated. He pulled out his penis and let out an audible sigh as he released his bladder. Midori smiled as she watched over his shoulder. She rubbed herself over the pants a little, already knowing how to punish him. As Charles shook himself off, Midori gently squeezed his ass.
"My turn," she whispered. "And when we go back to my place, I'm going to enjoy punishing you."
Charles put himself away and stepped back as Midori dropped her pants to her knees. She had apparently forgone underwear that day.
"So, when you move in, does that mean I can leave the toilet seat up?" he asked.
"If you're a grown woman with reasonable control, you shouldn't let yourself get so desperate that the second it takes to put the seat down is the difference between wet and dry panties," Midori responded as she watered the tree. "Just my opinion, though."
"I should have guessed." Charles felt himself rise in his pants as Midori's stream hit the spot next to where he had pissed. "So, what exactly are you going to do to me?"
"You'll see when we get there," Midori said as she wiped herself with a nearby leaf. "I'll probably enjoy it more, but you'll get something out of it, too."
The couple entered Midori's apartment, which was empty, as she had expected.
"Melanie disappears as she will, but if you need her, she's there," Midori said with a smile. "Okay, I'll make us some tea. You go in my room and...actually, you make the tea and I'll get it out."
Charles brewed some tea for himself and his girlfriend. Midori went into her room and took out what she wanted Charles to wear. She returned to the kitchen and sent him into her room.
"Don't come out until you've put the whole thing on, and that includes the underwear," she told him. "I'll change, too."
