Work Text:
Keith has recently had a surgery, and the pain meds had messed with his bladder so he had to wear pull ups. He’s not too happy about it. Involuntarily pissing himself isn’t exactly fun. It’s super embarrassing, but Shiro’s so sweet to him about it. And he’s actually a little bit.. well, enthusiastic.
Keith makes an offhanded comment about how gross and sterile the pull ups look one day. They definitely add insult to injury. Shiro takes note of this, and a few days later, a package of space themed pull ups is arriving at their door. Keith blushes and gets all shy, but shiro knows he secretly loves it.
Shiro takes care of him during the time he’s bedridden, reassuring him that he doesn’t think any differently of him or find him gross. Keith literally can’t help it, and he couldn’t make it to the bathroom even if he tried. And maybe keith exaggerates his symptoms a little bit…
He whines for shiro, asking him to change his pull up one day because his “arms hurt”. Or asking for extra reassurance when he starts to wet himself. Shiro’s boner definitely doesn’t go unnoticed, and from then on things change.
A few months later, once Keith’s no longer bedridden or wearing pull ups, Shiro takes him to a local fair as a treat.
Keith doesn’t realize that liquid goes through him SO fast, since using the bathroom hadn’t been on his mind for so long. At least not actually getting to a bathroom, that is.
After he’s downed his second lemonade, he can’t help the way he’s shuffling on his feet.
He’s dancing back and forth while watching one the rides when shiro comes up behind him, squeezing his thigh. Keith jumps a little, getting started. He feels himself leak. He whines, leaning back and pushing his face into Shiro’s shoulder. Shiro gives him a soft smile, playing with his hair. “Something wrong?” He asks, all nonchalant. Keith just shakes his head, and they continue on with their night.
By the time the sky has gone dark, Keith’s getting desperate. And shiro just keeps teasing him! Finally, keith breaks as shiro tries to slip a hand into his jeans. “Takashi..” he mutters, grabbing his arm. “I…I have to go to the bathroom..” he whimpers, face red with shame. He’s trying his hardest to hold it, pushing his face into Shiro’s shoulder to hide once again. But he’s just pulled right back out. “Mm? What was that, baby? Speak up.” Keith pushes at the arm holding the back of his neck (much like a mother carries a baby kitten) but he’s just met with a sharp tug. He leaks more.
“Bathroom.. I,, bathroom..” Shiro smiles at him, making him stand from the picnic table they were seated at.
“Yeah? You have to piss?” Keith nods, whimpering and holding his legs together best he can. Shiro kisses his head and guides him by the small of his back towards the bathroom. But at the last second he turns, ducking behind a trailer.
Keith feels like he’s in a daze at this point, the only thing he can focus on is not pissing himself. “Huh? Shiro? What are you-“ Shiro cuts him off as he shoves a hand between Keith’s legs. “Well? Do it.” He commands, and Keith’s head spins.
Keith frowns, “What?? Here? No, c’mon, shiro, we’re so close.” Shiro shakes his head and squeezes Keith’s cunt through his jeans.
“No. Only good boys get to use the bathroom. Don’t think you could make it, anyway. You waited until you ruined your underwear to finally admit you had to piss.” Shiro scoffed at him, chuckling. “Y’know, it’s almost like.. you wanted to piss yourself in front of everyone. Doing it in front of me isn’t enough for you?”
Keith whines deeply, shaking his head with distress. “No, no, Shiro, I- no, that’s not it, I..” words were too hard right now! “See? You can’t even make an excuse. I know what you want. Do it, piss. Now.”
Keith squirmed and tried to wiggle free, but was help in place by Shiro’s determined hand. “No! No! It’s not like that!” Shiro only rolled his eyes before leaning in close.
“Do it. Now. Do it before I shove my hand down your pants and force it out of you. Is that what you want, huh? You want me to stick my hand in your disgusting underwear and rub my fingers against your piss hole? I bet you’d like that. Needy bitch.” He gave another harsh squeeze to Keith’s pussy.
Keith only whined more, trying to wiggle out of his grasp as he started to tear up. “No!! No! Shiro- please!” He cried, gasping as shiro started to move his hand. “Stop! No! I’ll- I’ll do it. Please!”
He pushed his face back into Shiro’s shoulder as he finally let go, sobbing into him as he soaked his boyfriends hand and his own pants. He cried, “I’m sorry- I’m sorry!”
Shiro hushed him, kissing his head and rubbing at his neck. “Shhh, Shh, good boy, it’s okay.” Keith couldn’t bear to pull himself away even as the stream finally came to a stop, his face hot and covered in snot and tears.
“Shh, there we go,” Shiro palmed against him once more, earning one last spurt and a moan. “Is that better?” Keith nodded, hiccuping softly. “See? Shh, I know what you need. It’s okay. You’re so good for me, baby. I’ll take care of you. C’mon, let’s get you home.”
Shiro guided him back to the car, both of them thankful that Keith’s jeans were black. Keith still felt dizzy, and almost worried he might pass out.
It felt like some scene out of a movie, the way the lights were SO BRIGHT all of a sudden, and how the screams from the rides were ringing in his ears. His face was still soaked with tears, and he still felt himself hiccuping. He knew nobody saw them, but right now it felt like all the eyes were on him! He felt so embarrassed.
Shiro helped him into the car, even buckling him in. He kissed his cheek, so gentle like he worried keith would shatter at his touch. Keith slumped against him as shiro put a hand on his cheek, “Shh, you’re okay. We’re gonna go home, yeah? You’re so good, it’s okay. You were so cute standing there, wiggling against my touch.” Keith couldn’t help the way he squeezed his thighs together, his head was spinning, he felt so turned on. Shiro gave him a gentle, but mysterious smile as he pulled away.
Keith leaned against the cool window, his breathes panting as he urged his body to cool down. When they arrived home, shiro helped him out of his went pants and sopping underwear.
“Lay down.” He said with a small, fleeting squeeze to his cunt. Keith whined softly at the touch before doing as told and laying back on their bed. Shiro returned with wipes, nudging himself in between Keith’s legs.
Keith covered his face with his arm, feeling so exposed as shiro spread his legs for him, bending his knees. He groaned as shiro wiped him down, and gasped when he felt soft kisses pressed against his clit. “Mm, get up on your knees, sweetheart. You’re just as needy as I thought, huh?” He teased as he got up, and Keith’s head could only process so much at once.
He rolled over onto his knees, pushing himself up. He’s so focused on keeping his head straight that he hardly notices shiro stripping down to his boxers beside him. Soon he’s back in between his legs, though, pushing Keith’s head down into their mattress.
“C’mon, show me what’s mine.” He demands, and keith arches his back to show off his holes. “Better.” Shiro spits on Keith’s pussy, before spreading his thighs and pushing his tongue into Keith’s already soaked cunt.
Keith moans, leaning back onto Shiro’s tongue. This earns him a harsh smack on his ass, “Don’t fucking move. This isn’t for you, slut. You made a mess all over my hand and you think you have any right to be greedy?” Shiro pushed a finger into Keith’s cunt, fucking it in and out with no remorse.
Keith moaned, he just loved when shiro was rough with him. “Ghh- n-no sir!” He chirped out, gasping as a second finger was shoved into him. “Y’know, I could probably just shove my cock right in, huh? You’re fucking needy, not even tight when I’m giving you my fingers. Hm, maybe I should use your ass tonight? Bet your pussy would leak all over me, I wouldn’t even need to use lube.” He laughed.
Keith groaned at the loss of Shiro’s fingers, but was immediately rewarded with his cock sliding through his folds. Shiro tapped his cock against Keith’s cunt, his tip just barely pushing into him. “Please, please! Please nhh- I need it I need it shiro-“
He was only met with a sharp smack to his ass once again, before shiro pulled his cock away and gave his pussy a few slaps, too. Shiro rubbed his hand against Keith’s ass cheek, lining his cock up with Keith’s asshole.
“Mm, feel how wet my hand is from your cunt? You’re such a fucking whore, gushing all over me even when I’m slapping you. Gonna fuck your little Asshole, better hope you’re still loose from yesterday. Maybe..you’ll get so needy you’ll piss on me again. Make a big mess, huh?”
He gathered some spit and splattered it over Keith’s ass, before pushing his cock in. Keith moaned loudly and arched his back, shoving his face into the sheets.
Shiro chuckled and rubbed his back, leaving down to kiss his should blades. “There’s a good boy, looking so pretty for me.” Shiro cooed, before leaning back and spitting on Keith’s asshole again for more lubrication.
Keith whined as shiro started to fuck into him, gripping tightly at the sheets. Shiro rubbed at his clit, groaning as it made keith clench around him.
“Oh, you like that?” Keith whimpered and nodded. “Nhh- please, more, wanna cum please!” He begged, yelping when shiro smacked his cunt.
Shiro fucked into him harder, but made no more advances on his pussy which left keith aching for any kind of stimulation. He clenched down on Shiro some more, begging for him to take some kind of mercy on him.
Shiro groaned and smacked his ass, tipping his head back as he gripped Keith’s waist tight. “Fuck, you’re such a goddamn dirty slut. Just begging to be used, huh? You’re just a whiny bitch who needs his jokes stuffed.” He spat, releasing one of Keith’s hips in favor of shoving his fingers inside Keith’s mouth.
“Wet my fingers good enough and I’ll give you what you need, baby.” Keith was filled with a new vigor now, suckling Shiro’s fingers and swirling his tongue around the digits.
Soon he was rewarded with Shiro retracting his fingers and slipping them into his cunt, rubbing his thumb against his clit. All the while he continued to fuck into his ass, leaving keith a mess of moans and pants. He felt his orgasm building quickly, all of his senses filled with pleasure.
“Coming!!! Coming!!” He exclaimed as he spasmed around Shiro’s fingers, practically screaming as his orgasm tore through him. Shiro fucked him though it, slowly stroking at his throbbing clit.
Once Keith’s brain was no longer in bliss, he recognized another sensation quickly overtaking his pleasure. “Oh my god! Stop! Shiro stop stop!!” He sobbed as he started to piss for a second time, with no help from Shiro.
He just continued to fuck into him, groaning as his hand slid down to soak in his piss. Keith’s tears started to flow again, he couldn’t believe this was happening for a second time.
He sobbed and shook as Shiro finally came, his harsh grip on his hips sure to leave bruises. He rubbed his hand over Keith’s back before pulling out, carefully guiding keith to roll away from his mess.
Keith sniffled as he laid on his back, whimpering as he felt Shiro’s cum dripping out of him.
Shiro disappeared for a moment, returning with a damp washcloth and wiping keith down, before carefully lifting him into his arms.
Keith nuzzles against his chest, the sound of the tub filling up now registering through the fog of his brain.
Shiro kissed his forehead and brushed his hair out of his face before setting him in the tub, tugging off his shirt before climbing in after him.
Keith felt like jelly as the warm water covered him, closing his eyes as shiro pulled him back against his chest. “ ‘m sorry” Keith muttered out, his head lolling to the side to rest against Shiro’s bicep.
Shiro ran a gentle hand down Keith’s arm to soothe him, “Shh, baby, I’m not mad at you honey. You did so good, that was so hot darling.” He reassured, carefully staring to lather him up with his favorite body wash.
They both knew their safe word, and if Keith had uttered it at anytime Shiro would have immediately stopped. While it was overwhelming, it wasn’t a matter of a boundary being broken. Keith just experienced post-orgasmic guilt after particularly intense scenes, and Shiro always did everything he could to help with it.
Keith relaxed in Shiro’s touch, sighing softly. “Thank you for tonight, I needed that. I love you so much.” He whispered, giggling softly as shiro soaped up his sides.
Shiro pressed a kiss to his head, smiling and wrapping him up in his arms. “I love you too, my good boy.”
