Chapter Text
Serizawa felt distinctly nervous as they checked in at the front desk. He had only been partially joking about the reservation and he didn't think Reigen would go through with it. Yet here they are. He had sprung the surprise while they were out on a date.
The Prince Hotel was a convenient stop before Serizawa's apartment, a short walk away from their favorite restaurant, and in a discreet white building with only a neon sign of a crown. The front desk was modern and had the audacity to smell nice as well. The woman working the front desk didn't seem interested in them much, just friendly, and polite. Reigen handled check-in, and they were off to their room on the 5th floor.
"This way 'Tsuya," Reigen said as he led them down the hallway. Serizawa felt himself blushing as he watched Reigen in front of him. He had dressed in a different suit for their date. He had a brown coat and slacks with a brown and red Dupplin check vest, a white shirt, and a red tie. He had even taken his time to style his hair a rakish side part that had distracted Serizawa all night. Those slacks were doing everything for his ass, and the vest accented his slim waist. Honestly, Serizawa would have felt underdressed if it had not been for the sultry looks Reigen gave him over dinner.
Reigen held his hand as he led him down the hall, he blushed as he heard a few shameless noises from the other occupants. They got to their room and quickly went inside, as soon as the door closed, Reigen kissed him. His lips were soft, a little sweet from the dessert they ate at the restaurant. Serizawa hummed and attempted to deepen the kiss, but Reigen pulled away at the last moment.
"'Tsuya, what do you think of the room I picked out?"
Serizawa pulled his focus away from Reigen for a moment and looked at the room. His jaw dropped.
In the middle was a fluffy queen-sized futon with grey pillows on a black frame, the wallpaper was dark gray with black palm print. Reigen flipped on the light and the room was bathed in cool blue and white tones. Serizawa went over to the bed and flopped down on it. It was so soft, like sleeping on a cloud Reigen tugged on his arm to pull him up.
"C'mon 'Tsuya, check out this tub."
Serizawa allowed himself to be pulled up and to the bathroom. The tile was a marble white, and the tub was huge, enough that two people could bathe at the same time. Reigen smiled and pointed to the settings.
"It's also a jacuzzi," he said smugly.
"Wow, 'Taka, this is...this is wonderful," Serizawa murmured.
"This is one of the normal rooms, I didn't want to try a themed one, unless..." Reigen gave him a teasing look. "There was one that came with a sex swing."
How did Reigen know those words, Serizawa thought as he turned red. Reigen just laughed at him as he loosened the tie around his neck and started the tub.
"Why don't we start with a bath?" he says as he starts filling the tub and investigating the various bath salts and additives by sniffing them. Serizawa leaves him to it and goes to investigate more of the room. There is a big tv and a nightstand full of condoms, water-based and silicon lube, and even a flavored one. Serizawa picks it up and gives it a light sniff. It smelled like pineapple. He looked over at the other basket and blushed a 'massage' wand. Serizawa quickly looks away from it when Reigen comes in with a tin.
"I'm putting this in, it's yuzu scented. Is that okay, 'Tsuya?"
Serizawa puts down the little bottle quickly and Reigen peers over his shoulder.
"Oh-ho! Quite the haul," Reigen grins. "Grab those and put them in the bag."
"I should have known; of course, you'd be the type to take the little soaps and shampoos," Serizawa said. Reigen just huffs and walks over to the bed.
"They're complimentary, and they have to throw them out whether we use them or not."
Serizawa watches as Reigen takes off his suit watching the way his shoulders roll out of the jacket and those deft fingers start on the buttons of his vest. Serizawa swiftly goes over and puts a hand over Reigen's.
"Huh? Katsuya? Don't you want to get in the tub?" Reigen asked as Serizawa leans in and kisses him. Reigen moans and Serizawa slips his tongue in, Reigen pulls away for air after a few minutes.
"I want to undress you myself, where the hell did you keep this suit?" Serizawa murmured. Normally Reigen kept to his light grey suit with his signature pink tie. He must have rushed off to change after their last customer.
"I bought it with my first paycheck from the Water Cooler Company. It was too nice and a steal for the price. Do you like it?" Reigen asked a sly lilt to his voice.
Serizawa had wanted to rip it off him the instant he laid eyes on it. His hand brushed over the buttons of the vest, as he gradually unfastened them. He did like the suit and he wanted Reigen to wear it again, after all. He pushed off the vest and used his powers to fold it neatly and ran his hands down Reigen's chest to his waist. He felt Reigen shudder under his hand and decided to focus on his button-up, taking that off slowly as well.
"C'mon 'Tsuya, we need to get in the bath before it gets cold." Reigen urged. Serizawa did want to get into that big tub, but he had a job to do. Shirt off, Reigen's bare sparsely haired chest was his to admire. He leaned in and rubbed his face on the skin there. Reigen smelled of sage and sandalwood (a sign that he had dabbed on some massage oil in lieu of cologne). He didn't linger though, just enough to see the goose flesh rise along the other man's arms before pulling away. Reigen let out a frustrated noise made to pull Serizawa back in. Serizawa stopped him and pecked his cheek.
"I am helping you undress." Serizawa scolded. Reigen just sulked slightly and nodded for Serizawa to continue. The belt was next which Serizawa coiled up and set on the table. Serizawa knelt, unfastened the top button, and unzipped Reigen's slacks.
A soft moan fell from Reigen's lips and Serizawa looked up. The other man was staring at him with dark eyes, biting his lip. Serizawa wanted to stand up and push him down onto the bed, but he had committed to this bit, and he was not going to stop now.
He did, however, pause at the sight of Reigen's partial erection and at the underwear he was wearing.
"Is that a silk jockstrap?”
It was a pretty, floral partnered thing made of light pink lace.
"Yeah...looked better with the lines of my suit than boxers or briefs," Reigen said as he ran his hands down to push the fly of his slacks further apart. Serizawa swallowed hard and kept his hands firmly on Reigen's thighs. He moved them down and pulled up one pant leg and noted the socks and garters and removed each shoe. He wanted to leave the garters on, but they were getting in the tub after all. Finally, his hands returned to Reigen's waist and pulled the slacks down. Reigen was fully hard now, the pretty pink floral pattern visible against the hard line of his cock. Serizawa put one hand under Reigen's knee.
"Lift your leg up, please?" He asked, Reigen did, and Serizawa helped him step out of one leg and then the other. Reigen was almost naked now (except for that damn jockstrap), he stritched Serizawa's scalp as a thank you and walked past him into the bathroom. Serizawa was as hard as a steel beam, and he took a moment to catch his breath and cool down his heated face.
What the fuck was that? That did awaken something in him, but it was too loaded for him to unpack this second. Serizawa stood and removed his own suit swiftly and folded it with less care than Reigen's and followed the younger man in. He saw the lacy jockstrap on the floor and mourned not being able to remove it himself. Reigen was washing himself off with the shower head, and Serizawa's eyes were drawn to the water running down his back and the silvery scar that ran from his shoulder to his left kidney. Even though Reigen could not see it and said it did not hurt him; it still made Serizawa wish he could smash Sakurai into the pavement. Serizawa sat down on the little plastic stool behind Reigen and offered to wash his back. He even did a little massage, remembering what Reigen taught him, and smiled when the tension ran out of Reigen's back and a sigh fell from his lips.
After they cleaned themselves off, Reigen stepped carefully into the tub and sank down to his shoulder.
"God, you have to get in 'Tsuya..." Reigen moaned as he leaned into one of the jets. Serizawa got in and groaned as the jets massaged his back.
"Only a little better than an onsen," Serizawa admitted, Reigen hummed in agreement and stood up abruptly.
He's still hard, Serizawa thinks as Reigen turns and sits on Serizawa's lap in the tub, his ass nestled right against Serizawa's erection. The blond leans back and rests his head on his shoulder.
"This is lovely," Reigen purred, and Serizawa had to agree. The jets were at full blast, the water warm and citrusy smelling, it was lovely. "We need to use this thing at least one more time before we check out."
They sat like this for a minute then Serizawa felt Reigen pick up his hand and pull it on top of his erection under the water. Serizawa opened one eye to see Reigen grinning at him cheekily. Serizawa rolled his eyes and took him in hand stroking slow from base to head, letting his thumb linger on certain spots that elicited a breathy gasp from the younger man.
"You just want to be spoiled today..." Serizawa murmured. Reigen rocked his hips up, his ass pushing back against Serizawa tantalizingly soft.
"Maybe..." Reigen panted, his hips thrusting a little faster into Serizawa's fist. Serizawa watches the flush spread from Reigen's face to his chest and shoulders, the little furrow of his brow as he focused on the draw and pull of their movements. Serizawa gently pushed Reigen up a bit so that he could trace Reigen's perineum to his opening. It was a little loose already from the warmth of the bath, enough so that Serizawa could slide one finger in without resistance. Reigen whines and sways a little, on his knees now in the tub, giving Serizawa a wonderful view but also making him realize something.
"Let's get you out of the tub before you overheat."
Serizawa removes his hands (Reigen's protests are noted but ignored) and helps his boyfriend stand and exit the tub. Reigen's face is red, and he seems to gain more of his wits now that he is in the cool air of the room. They dry off and set the tub to drain; Reigen flops onto the bed and stretches himself out. Serizawa floats the jockstrap to his hands and slips it back on.
"I wanted to take this off myself," Serizawa explained clearing Reigen's confusion. He kisses Reigen deeply and slithers down the bed to tongue the lacy fabric. Reigen is leaking already, and Serizawa hopes the fabric is easily cleaned as he takes Reigen down to the base. Reigen cried out, loud and clenched at the bed, trying not to choke Serizawa (not that he would have minded but again, a kink to unpack at a later date). The younger man tasted clean and a little salty and bitter from the precum, Serizawa moaned around him which caused another string of babble to be gasped out from Reigen's lips. Serizawa floated a bottle of lube from their bag and slicked his fingers when he caught a whiff of pineapple, shrugging; he carefully eased one finger in and stroked. The high whine that rewarded Serizawa sent a jolt to Serizawa's erection, which was being woefully neglected. Serizawa backed off to catch his breath (and cough a little bit) and turned Reigen onto his stomach and pushed his cheeks apart. Reigen was trying to catch his breath and Serizawa couldn't hold back the grin as he touched his tongue to Reigen's entrance and the loud yell that he let out.
"AH! 'Tsuya..!"
The pineapple lube was very faint, and very artificial pineapple but tolerable as Serizawa licked his way in. Reigen didn't allow him to do this often, it melted his brain too quickly, but Serizawa loved seeing Reigen lose control. Reigen thrust his hips back onto Serizawa's tongue and Serizawa obliged him by thrusting his tongue in deep enough to make the man keen and go boneless onto the bed. His tongue retreated and Serizawa was able to press two fingers in easily as he floated the mouthwash over (otherwise Reigen wouldn't let him kiss him on the lips). He swished, grimacing at the combined taste of mint and pineapple, spit into a little cup, and then tossed it into the trashcan all while stretching Reigen open on his fingers.
"Come on 'Tsuya...please I'm gonna!" Reigen sobs as Serizawa pushes in a third finger. Serizawa knows he won't last any longer and deliberately presses around his prostate, which earns a frustrated grunt. "'Tsuya I know you fuckin' teasing me can you not-aaah!"
Serizawa presses all four fingers down and rubs and Reigen shakes apart around him, good now Serizawa can take his time (not that it'll be long, but he likes to go at his own pace). Serizawa stands (ooh, he's only 32 knees should not make that noise), and flips Reigen over onto his back. The lacy jockstrap is soiled, the pink run-through with white and Reigen looked thoroughly out of it. Serizawa fetched a condom and rolled it on with a little more of the pineapple lube, he found the firmest pillow and placed it under Reigen's back. Taking a deep breath Serizawa thrust in, Reigen was relaxed and warm inside, it didn't take him long to be fully pressed inside. Reigen softly moaned the whole time and reached for Serizawa. Serizawa could not resist and leaned in for a kiss as his hips shifted and he began to move.
Reigen is slow and languid, and Serizawa coaxes him slowly back into arousal. Their kisses are sloppy and wet as Reigen pants and groans into his mouth. Reigen throws his head back as he comes again whimpering with sensitivity and then in disbelief as Serizawa bites his lip and keeps going. Tears leak out of the corners of Reigen's eyes as he comes again, shaking and Serizawa finally follows him with a low groan.
Serizawa slowly pulls out, Reigen flinching with sensitivity at the motion and collapsing face-first on the bed. There is a sated sort of quiet that is all over them as Serizawa can barely muster the energy to move let alone get up. He hears Reigen shuffle and snuggle close to his side. He smells like sweat, yuzu, and (very faintly) pineapple.
"Can you move?" Serizawa asked, finally lifting a hand to place it on Reigen's hip.
"No, y'melted my bones..." Reigen slurred but he looked beyond satisfied. "Y'like m'new underwear I guess?"
Serizawa pushed himself up and tried to stand, it took one try, and he was proud of that. He was able to walk to the bathroom for a washcloth. When he returned, Reigen had managed to roll over onto his back, the underwear was soiled, and Serizawa hoped it could be rescued with some washing (probably by hand).
"For special occasions only," Serizawa muttered. "I don't think I can handle you walking around the office, knowing you have those on underneath."
Reigen looked so smug that Serizawa just threw the cloth at his face, getting an indignant squawk of surprise. He flopped down on the futon and pulled Reigen to his chest, in his haste he had neglected a ritual. His lips brush against Reigen's shoulders and neck lazily. Reigen didn't move much except to toss the sticky, jockstrap on the floor.
"Gross, 'Taka."
"Yeah? Well, they'll have to clean the room too and I am sure they have seen worse." Reigen snarked as he rolled and squirmed until he was facing Serizawa's chest and grappled him like an octopus (good thing Serizawa did not need to pee just yet).
"How long do we have this room?" Serizawa asked, not wanting to move from this spot for at least eight hours.
"Booked it for the night. We leave tomorrow at 11 am. We have to get in that tub again, make the most out of this."
Serizawa let himself relax at the news and let his eyes droop closed. He vaguely heard Reigen mumble something about smelling like a pina colada before falling rapidly to sleep.
