Warnings: watersports aka PEE AND PISSING

Pressure built inside of Marth’s admittedly weak bladder. It was embarrassing. Humiliating even. Ignoring the stuff with his father, there was a reason why he avoided drinking soda, juice, and tea while out in public. Hell, he only drank water when completely necessary. It was all to avoid having to go to the bathroom every other hour—or less—or wetting himself like a child. However, the mission to Mementos was rough. The best way to heal was to eat and drink everything that his lover, Ren, had brought from the other world. His spirit was low from casting one too many Bless skills that may have or may not have worked. The best way to restore that spirit was with something called Arginade. It did not taste good. But, he’d rather drink that than the water with placenta floating about in it.

There was also the ‘ice’ coffee that Ren had brewed himself.

It all happened to run right through Marth.

The prince squirmed in his seat. A hiss spilled from his lips each time Morgana hit a bump or turned a little too quickly. Makoto was easily the best driver in the group, however, Haru wanted a turn. He adored Haru. However, she could not drive to save her life.

He swore that he could feel the urine sloshing inside his bladder. He keened before hunching over. His gloved hands rested on his stomach. It didn’t do anything to ease his discomfort. He simply just couldn’t handle it anymore.

“Woah, Lodestar, are you okay?” Panther, also known as Ann, a dear friend of his, asked. Her hand rested on his shoulder. “Were you hurt? Guys, pass him a Nastea or something.”

Before Marth could protest, a bottle was cracked open and passed to him. He gulped. The sound of liquid splashing about and the sensation of it in his hand made him wince. His bladder throbbed. A burning pressure swirled inside his bladder. Even his kidneys began to hurt from how badly he needed to go... but the sight of Ann’s big, expectant blue eyes staring at him made him want to weep. She was so caring. He couldn’t just ignore her compassionate attempt to help!

Knocking his head back, Marth gulped down the whole bottle in one go. Iced tea splashed against his walls. His stomach groaned.

The young man squirmed, crossing his legs tightly together, as he gave Ann a nervous smile. “Th-thank you, Ann... I-I feel a lot... I feel a lot better,” he lied.

“Pull over, Mona and Noir,” Ren called out. “I need to pee.”

Makoto scoffed as the bus slowed down to a crawl. “Can’t you wait until we reach the surface?”

Ren shook his head. “Nah. Gotta go real bad. Anyone else need to go?”

“Actually...” Marth mumbled, only to get cut off by Ryuji who crawled over his lap to get to the door.

“Yeah man, I gotta take a leak too actually! I’m full to burstin’!” The blonde’s knee knocked into his stomach. Unintentional pressure pushed itself onto Marth’s already weakened bladder. Panic pulsed through him as he felt a squirt of piss gush from his tip.

The prince whined as he quickly followed Ren and Ryuji out of the vehicle and walked a couple of feet to get some privacy. Blood rushed to his face and buzzed loudly in his ears as he heard the girls snicker behind him.

His hands scrambled to undo his belt and push his many layers out of the way. The leather hit the dirty Mementos floor in a heap as he tried to keep his tunic out of the way. An utterly pathetic whine escaped him as he tried to push his spats out of the way. His knees bounced up and down as he marched in place. Piss continued to slosh and splash inside of him during his struggle. It only made things worse but he just couldn’t handle it anymore!

“Damn! You really had to go, huh, Lodestar?” Ryuji asked before pissing beside him. The spray of his urine was like a punctuation to his question. The strong stream splashed against the stained concrete. Tiny droplets bounced off the surface and scattered across the pathway. A deep, shuddering, and utterly satisfied sigh escaped the man. Trembles ran through his body as his stream slowed down to a trickle and then a few drops. He huffed before shaking his enormous cock—Gods, why was Marth staring? How could he not stare—to get rid of the last few drops before tucking himself away. “Alright, buddy. I’ll get out of your hair since you’re so pee shy. Hurry up and go too, Joker.”

“Yeah, yeah,” Ren said as he waved his friend off. Once he was gone and back inside the vehicle, the brunet turned towards his lover. A smirk split itself across his lips. Thanks to the sharp domino mask, he looked malicious as he stepped towards Marth. To the prince’s utter confusion, he dropped to his knees in front of him. “Piss in my mouth, Lodestar.”

“Wh-what?! I-I couldn’t! That’s...” Marth sputtered as the pressure continued to grow and grow. His muscles began to cramp in his groin and lower back. It only grew worse once his boyfriend’s hands reached for his spats and yanked them down to his knees. His smirk grew wider, almost maniacally so, before he pushed three fingers against his pelvis. “R-ren—Joker!”

“C’mon. You gotta go anyways.”

“But... d-don’t you have to go too?! Wouldn’t this make it worse...”

“I lied. I saw how you were struggling and decided to help you out. Let me help you even more, Marmar.”

Keening to himself, Marth finally gave in. He shuffled towards his boyfriend and held his slowly stiffening cock—no, why was he getting hard—to his lips. His eyes screwed shut as he tried to imagine rushing water. His cramps only grew worse as his body refused to go. He needed to piss! What was going on?!

The sensation of a wet tongue lapping against his twitching cock brought him to the world of the living. Pants fell from his now gaping mouth as he stared down at Ren. “Relax. I want this. You need this. Just let go,” he whispered. Stars shone in his dark, needy eyes as he mustered all the charm he could. “Piss in my mouth.”

Marth shuddered. His eyelids fluttered closed as he tried to relax. His boyfriend’s kitten licks against his cock were both a blessing and a curse. Sudden wet warmth caressed his tip. His breath hitched. Ren was sucking his cock. Twitching, his cock grew to full mast as piss finally began to escape.

Strong in both taste and smell, his piss flooded Ren’s eager mouth. That painful pressure slowly dissipated as he emptied his bladder inside his boyfriend. It almost hurt. However, Marth was unable to stop. He didn’t want to stop. Not when he was finally achieving release. He felt Ren greedily swallow what had pooled inside his mouth. One, two, three mouthfuls were chugged down before Marth’s piss stream slowed down. Finally, he was done. Droplets dripped from his aching slit onto Ren’s piss-stained tongue. He shivered in delight as Ren’s tongue lapped against his tip before circling around it. It dipped into his foreskin to scoop up any piss that may have tried to escape.

With a loud pop, Ren pulled his mouth away and wrapped a gloved hand around Marth’s regrettably stiff cock. “Looks like I’ll have to help you with this too huh? Better make it quick, Marmar... The others are waiting.”

Without a word, Marth gripped his boyfriend’s messy locks and sheathed his prick into his wet mouth. His balls smacked against his chin. Desperately, he rutted against that devilishly wet muscle. Moans fell from his drooling mouth. His fingers tangled themselves inside ink-black hair as fucked the tight little throat. His cock bulged in his throat. Then, he came. Cum pumped itself into Ren’s stomach as he bottomed out.

“Hah...” the prince sighed before pulling out. “Thank you so much. I love you.”

“Anything for royalty, my prince.”
