“Is everything okay? You’ve been fidgeting a lot.”
Mina sighed, forever hating how perceptive Kirishima Eijirou could be. Although to be fair to him, she wasn’t exactly hiding how much she was moving around on his lap. She debated if she should tell him the truth: that she was fidgeting because her bladder was on the verge of bursting.
“I’m fine, Kirishima. Thanks.”
They were on a road trip, all crammed inside Kaminari’s tiny car, on the ride across Japan to go to some resort he had wanted to go to. Jirou was upfront with Kaminari in the passenger seat, controlling the music for their trip, while Mina sat on Kirishima’s lap in the back, crammed alongside a mountain of luggage.
It had been hours without seeing an open rest stop and the strain on her bladder was finally taking its toll on her. She hoped she wouldn’t have to say anything, that they’d find a rest stop and her embarrassment would be saved. But now that Kirishima had picked up on her fidgeting it meant he’d pick up on it soon enough. Sure, he wasn’t the brightest, but Kirishima was perceptive when he wanted to be. Scarily so. Almost like Ochako could be.
That little traitor was getting a bullet train to meet up with them later tonight instead of driving. Not much she could do about her scheduled patrol this morning, but Mina would still blame her for the current predicament.
“Are you sure? If you’re uncomfortable I can try to move but, umm,” Kirishima coughed awkwardly from behind her before he leaned in a little closer to whisper to her, “I would appreciate it if you could stop moving so much. I’m getting a little excited under you right now.”
Kirishima of all people would phrase it like that. Mina’s cheeks couldn’t help but flame with embarrassment. She debated telling him the truth, trying to think of a lie, but after a moment she let out a sigh and realized she should probably be honest with him, whispering back to him so that Kaminari and Jirou wouldn’t be able to hear her over the loud music. At least there was one thing she was thankful for riding with them.
“I really have to go pee right now. All the rest stops have been closed so far. Sorry, Kirishima. I’m not trying to move around so much.” She was sure she mortified the poor man before he finally spoke up behind her.
“Denki has leather seats. Why don’t you just do it here?” he whispered back. “I, um, wouldn’t mind.”
Mina twisted around to glance at his face. His cheeks were nearly as red as his hair and it took precisely two seconds before she realized that he wasn’t just telling her that just to be a “good bro” for his friend.
“Are you into this, Kirishima?” His silence in return and guilty looks were all she needed to know he was. She couldn’t help the sly grin on her face. The energy had clearly shifted here. Mina wasn’t nervous about losing control anymore. If anything she had nothing but control over the situation. She sat back more fully, finally able to feel the half-hard boner of his digging into her ass as she leaned back against his body. She looked up at him, still smiling that foxy smile of hers, and whispered, low and seductive, in Kirishima’s ear. “Would you like it if I pissed on your lap, Kirishima?” She swears she could feel the way his dick swelled in response.
“Yes,” he admitted. “I’m sorry, Mina, it’s not very manly of me to get off to the situation you’re in.”
“Don’t be,” Mina replied, as if it were obvious. “If you ask me, we both have an issue we need taken care of. Can you see if you can grab the towels from my luggage? Should be in my beach bag.”
Kirishima obeyed her request, reaching out to rummage through the luggage while he searched for Mina’s elusive beach bag. She was almost worried that it was buried underneath the pile, or on the opposite side of the car, before he made a small noise of discovery and dragged her bag toward himself, and reached inside for some towels. Mina did her best to stand, gripping the back of Kaminari’s seat and praying that he wouldn’t turn around or notice what was happening right behind him while Kirishima got the towels beneath his body.
Once he was finished, his hands gripped Mina’s hips and dragged her back to sit on his lap. He was even harder now, and Mina’s jaw popped open at the feel of it. Kirishima was big . It didn’t just stop at his height or stature, given the beast she could feel pressed against her clothed cunt.
“Is this okay?” Kirishima asked. His voice was low and husky, yet uncertain, and Mina decided that after this she would definitely be dragging him to her room for the duration of their trip.
“Perfect,” Mina responded. “Are you sure you’re okay with this? It’s going to be kind of obvious when we get out of the car later. And the smell…” Mina’s voice trailed off. What they were doing was risky and stupid. She should be making Kaminari pull off to the side of the road, not pissing on Kirishima’s lap, and all over his backseat.
“I’m sure,” Kirishima responded, voice tight. Like he might combust if Mina told him no. She was almost tempted, just to see and hear his reaction. To push his buttons and see if he would take more control. Although something tells Mina that he likes this vulnerable position he’s in. “Don’t worry about it, Mina. Just please. ”
That was the only thing she needed to hear before she slowly eased her bladder. It took a few seconds, a little shy, but once she started to go she couldn’t stop if she wanted to. She leaned back into Kirishima’s warm, broad chest, and let out a pleased groan while her piss soaked through her jean shorts and into Kirishima’s denim below. It was impossible to hear the stream hissing against the front of her shorts with the music blasting up front, but Mina could feel it all the same.
Kirishima’s hands roamed along her sides, too nervous to make a move, but once Mina’s bladder was finally empty she rolled her ass against his crotch, digging the seam of her shorts into her own cunt in a way that dragged deliciously. It’s as if that movement snapped something inside of him. He just couldn’t resist.
Kirishima’s arm snaked around her waist, holding her in place while he thrust his hips against her, grinding against her as he huffed in her ear with each tiny movement. His other hand reached down, unbuttoning her shorts, and slipped inside.
“No panties?” Kirishima asked. Mina chuckled softly, turning her head to look up at Kirishima’s disbelieving face.
“Disappointed?” she teased.
“Never. Fuck , Mina. You’re so hot. I can’t believe you’re letting me touch you like this.”
“Maybe we should pinch each other to make sure it’s not a dream.” What she didn’t expect was for Kirishima to follow through, pinching her clit sharply which made her let out a shriek. Both from the sudden pain and the shock. “Kiri!” she snapped. Any protests died on her lips as the music lowered.
“You two alright back there?” Kaminari called back. Mina looked up, able to see his eyes watching her in his rearview mirror. She put on her best grin, hoping it was convincing. Kirishima’s face looked nonchalant, gazing out the window, but his fingers continued to play with her clit and god Mina was going to kill him for this. Somehow the idea of talking to Kaminari while Kirishima continued to play with her idly just made her hotter, though.
“Yeah! We just-” Mina’s breath staggered as Kirishima pushed two fingers into her sopping entrance. They were so large and the stretch felt amazing, but she needed to focus. Even as he slowly pumped them inside of her and rolled his thumb across her clit. “Kiri accidentally stepped on my foot when we adjusted,” she lied. Kaminari’s eyebrows squinted but he seemed appeased.
“Alright. We’re almost there at least. Sorry for the cramped seating.”
“It’s fine! Just how the cards fell,” Mina laughed, waving her hand to dismiss any sort of concern he had.
“Just let me know if there’s anything you need.”
I need you to turn the music back up so Kirishima can make me cum already. “Of course! Thanks for driving us, Kaminari.”
He gave her one last glance in the mirror before he shrugged and turned the music back up. She could see him turn his head, speaking to Jirou, but couldn’t make anything out from where she was while Kirishima pulled his fingers from her cunt. Her head fell back on his shoulder and she let out a whine while Kirishima chuckled from beneath him. She could feel his laughter vibrating through his chest and he lowered his mouth to her throat, sharp teeth grazing across her skin as he nibbled at the skin there. He latched his mouth over her soft, pink skin while he gripped the material of Mina’s jeans and pulled so that the seam dug in between her lips.
He found a rhythm, Mina’s hand raising to cover her mouth and smother her moans, while Kirishima continued to grind against her with the beast in his jeans. He tugged on her shorts with each thrust, dragging the material up repeatedly against her clit. It was rough but felt so, so good.
“Kiri-” Mina panted. “I’m going to cum. Don’t stop, please,” she begged him softly from beneath her hand, only lifting it enough to whisper those few words before she covered it again. Kirishima obliged, keeping up with the pace he had set before Mina was coming undone on top of him.
Her eyes rolled to the back of her head and her face scrunched up. She raised her other hand to her mouth, not trusting the one to keep back the cries that spilled from her lips.
Kirishima was kind enough to release her shorts, tugging them gently so they were no longer snug between her lips, and let her come down in her own time. He raised his mouth from her throat, shushing and soothing her quietly while his hand around her waist began to rub back and forth on her abdomen in something he hoped was comforting.
Several moments passed before Mina took in a deep breath and released it, totally relaxed. It was then that she noticed Kirishima was still rock-hard beneath her. That wouldn’t do at all.
She sat up a little bit, bracing herself where she could, before she began to roll her hips against his, grinding against his wet crotch. She wished she was facing him instead so she could see the faces he made alongside his quieted moans. She could hear the quiet schlick as their wet jeans rubbed together and she did her best to keep up the pace while Kirishima’s fingers gripped roughly into the door’s handle.
It wasn’t much longer before Kirishima was moaning Mina’s name before cumming in his jeans with a low groan while Mina wiggled her hips back onto him and sat back down. She couldn’t help but giggle, feeling indescribably naughty at the fact that she had pissed in Kaminari’s backseat and gotten off with Kirishima.
The rest of the ride went by without a hitch now that Mina’s bladder was empty and Kirishima was clearly satiated and basking in the afterglow. Even if she had made him cum into his pants. By some miracle, they were also able to redress and tuck away their wet clothing and towel on the floorboard where Mina could grab it later.
When they finally arrived, Kirishima grabbed Mina’s hip, leaning forward to speak to her.
“Maybe a little late to ask, but would you be interested in dinner sometime?”
“I’d love that,” Mina agreed.
Mina basked in the feeling that she had gotten away with what happened. That is until Kaminari came up behind Mina and whispered to her.
“Next time you want to fuck in my car just ask.”
