Thoughts on sex toys? Who tops during sex? How do they like their sex? How rough can the sex get before it's taken too far? And then some... (Most of these questions are answered in theory.)

PLEASE SEE THE END OF THE CHAPTER FOR THE WARNINGS AND IMPORTANT AUTHOR'S NOTE. This one earns the "Mature" label VERY. MUCH. Basically the entire explicit scene is cut, but ... yeah, you better read the ending note, my dears.

Takami pushed his glasses further up the bridge of his nose in astonishment. It was just a few days after the small group of Americans had left. Summer was in full, humid, sunny swing, Tokyo's skyline a hazy, indistinct wavering in its heat. This day in particular was sunny and bright (though that wouldn't necessarily make a difference, as past experiences had proven), in other words, the perfect day for running up a certain renowned mountain. But for some reason, Shin had tracked Takami to his familial home- his retreat during the school breaks, why spend more money?- and was currently standing on the older man's stoop. In the stern-faced linebacker's hands, he held out a folded piece of print-paper, whatever being printed on it hidden within the folds out of sight.

"You need what from me exactly?" Takami inquired curiously as he took the paper.

"Help with the internet research required for this project. A personal one." Shin answered bluntly. His frowned darkened slightly. "I went to the library. The attendant did help with some pertinent books and journals on the subjects, but much of it is online only. They didn't think it appropriate to use the library public computers for this kind of study."

Takami's eyebrows shot up, glasses slipping down his nose. He unfolded the paper a second later, frowning incredulously. "Just what kind of research are you conducting, Shin?" His frown was almost Shin-levels of intensity as his dark eyes scanned the page. "These all seem to be personal blog sites. A few look a little less amateur, but… can't you just look these up yourself?" Takami's eyes didn't rise from the paper as he spoke, mouthing a few of the stranger-looking blog-titles silently. Some of the web domains and the end of the urls were very… odd.

"I attempted to do so. The keyboard was defective and flimsy. I was asked to leave when I requested a replacement," Shin replied calmly and without a trace of shame or guilt.

Takami barely restrained a snort. "All right. I'll help." Mostly just to satisfy his own curiosity. "How soon do you need it back?"

Shin glanced away, arms crossing over his chest. "I understand you have private affairs to attend to, but I prefer it as soon as possible."

Any minutes now, Takami would stop being startled by this conversation. Or anything Shin ever did.

"I see," Takami drawled, hiding his actual reaction under his own, smirkier, poker face. "I'll attempt to return it within a week."

For a moment, Shin's perfect stoicism broke. Flared nostrils, the corners of his mouth and eyes tightening, barely betraying an expression of impatience. The stone-faced scowl slammed back down as he reined himself in and nodded once, briskly.

"My thanks."

And with that, he took his leave.

"You're welcome and good-bye, Shin," Takami huffed amusedly. "Let's go see what our strange friend is up to," he muttered to himself, backing into his home and closing the door.

Three days later, a thick manila envelope made its way to the Shin residence. Return address: Takami's. Shin accepted it from Hoshino with a puzzled frown and distracted thanks. Taped to the back was a small, single sheet of paper folded into eighths.

I implore you to figure out how to use your own computer. I must respectfully decline any such research assistance you may require in the future. Good luck in your …endeavors. The note read simply.

"Good news, dear?" Juuri queried in concerned interest.

"Yes and no," Shin said slowly, carefully re-folding the note. "It seems I need to sign up for computer classes this fall."

Juuri and Seisuke exchanged baffled, but amused glances.

"Son, you need technology lessons," Seisuke joked before booming with laughter.

Juuri placed her fingertips to her mouth even as her lips curved upwards. "Perhaps one of your friends would be better suited to the task? Sena-kun, even?" she suggested.

"Hn," Shin grunted pensively, then set his chopsticks to the side. "May I be excused?"

He had some reading to do before training, after all.

Sena opened the door later that same day. He was smiling brightly and still damp from the post-practice shower. His shoulders were slumped with that familiar weariness the best training wrought, and he wore the sort of clothes he only ever wore at home. Sweatpants with holes at the knees and a t-shirt faded from washing and loose around the neck. A lazy greeting had Shin waving towards Monta, who was sprawled across the couch, lethargic and mostly unconscious. Shin stepped into the apartment and out of the heat gratefully. Due to his own daily routine and practice, he had taken his own shower, but hadn't quite dried before throwing on clothes to get to Sena's after Sakuraba announced his text. His clothes stuck to him awkwardly thanks to sweat from humidity made even worse from shower dampness.

"I'm surprised you came so quickly! I was expecting you after dinner. How was practice?" Sena asked, already handing over a glass of iced barley water.

Shin chugged it down gratefully. He froze, pulled the cup from his lips, and then stared down at it, eyebrows high. Sena pressed his lips tightly together to keep from bursting into laughter at the scandalized expression.

"It's just a little bit of cinnamon, Seijuuro."

Shin flicked his gaze up at Sena, one eyebrow still high, before finishing off the cup. "Thank you. It's not bad."

"Sounds like ringing endorsement. Come on, let's go lay out in front of my fan and listen to some podcasts I downloaded. You'll like them."

"I will?"

"Yup," Sena replied cheerfully.

"I wanted to have a discussion with you," Shin protested bemusedly. The privacy of Sena's room, though, was better than having the talk in the living room next to a snoring Monta. He followed on Sena's heels to his bedroom. "Where's Riku?"

"He went out to meet up with some friends. I think some of the Takekura guys, actually," Sena explained easily, already across his room and fiddling with his computer.

"Good."

Sena looked over at Shin in confusion at that. "I thought you liked Rikku-kun?"

"Not the matter at hand. Can you please come sit down?" Shin entreated, gesturing towards the open space on the bed next to him. Sena blinked, but obediently walked over and sat down.

"Is everything all right?"

"Yes, everything is fine. However, I had a feeling that we should discuss a certain aspect of our relationship after the last…last occurrence…" Shin frowned as he stumbled over the right word to use.

"Occurrence? I don't- Is this about the not telling you everything? Because I get it! Really! I'm more than willing to share more and not think I'm a total downer or bother. I get that those things matter to you just as much as they matter to me! Really!" Sena exclaimed, hands clasping around one of Shin's, brown eyes earnest and mouth firm with resolve. Shin couldn't help but trace his thumb along the bottom of Sena's lip, fingers holding his pointed chin gently. Sena didn't look away or get nervous. Just kept his gaze steady on Shin's.

"I was talking about our sexual experiences, Sena."

There was the blushing and rapid back-flailing. Sena squeaked and almost flailed himself off the bed, face tomato red and eyes wide.

"Our what? No, wait, don't repeat it!" Sena hissed, slapping his hands over Shin's mouth. The look Shin gave him was the epitome of unimpressed. Sena chuckled weakly and let his hands drop. "I me-mean, o-of c-course you can! C-Cause we're a-adults."

"Yes." Shin gave Sena one last lingering look, then reached in his pocket and took out a single, much-folded piece of paper. "This is the list I made using the information your friend Emily gave me and the research from that list."

"E-Emily? Oh! The paper she gave you at the airport?" Sena asked with dawning understanding. He took the paper offered as Shin nodded his affirmation.

"This isn't what she gave me, how-"

"Oh my god." Sena shrieked, luckily high-pitched and breathless, so the sound didn't escape his room. His blush, which had been gradually fading, returned in full force, from his hairline and all the way down to his collarbones. He slapped the paper flat to his chest and stared at Shin, eyes bulging and jaw hanging almost to his knees. "This is a- Is this a kink list?"

"Ah, kink. The sexual predilections of a person."

"I know the definition, Seijuuro!"

Shin slipped the paper out of Sena's admittedly weak grasp and smoothed it over his thigh. "I believe this list could be termed so, yes. After the last time, we discussed my… kink for leaving a…mark behind, and how you were not adverse to it."

"How can you make this sound so dry?" Sena murmured to himself incredulously.

Shin's mouth twitched, but he forged on. "When I realized just what Emily had given me, I decided to do thorough research on the topic of sexual tastes, or kinks, so that we may apply them to us."

Sena was still gaping and flushed an extremely concerning shade of red. Shin frowned lightly, a bit of uncertainty settling in his shoulders. Shrugging the tension aside, he glanced back down at the paper. "I'm not experienced in these things. I don't like not understanding what I want, or how I feel."

"J-Just like when I told you I liked you over a year ago. You researched romance and dating and… and stuff, just so you could be sure of what to say to me," Sena realized slowly. Shin nodded, relieved. "I g-guess this makes sense. And… maybe it's b-best…" Sena fidgeted a bit, fingers twisting and wringing agitatedly. "Now that we're actually doing this, talking about it, and what we like or think we might like, that's…that's a good thing."

"I don't like going in blind," Shin agreed readily. Sena laughed and rubbed the back of his neck, his flush down to a more normal pink shade. Thankfully. Shin really was getting anxious over that. He had almost turned purple for a second.

"So… umm… the list?" Sena stuttered, holding out his hand. Beckoning. Shin handed it back over willingly. "Did you put them in any preferential order?"

Shin shook his head. "I merely put them in alphabetical order. I did not want my opinion to sway yours before you could even look."

Sena grinned awkwardly, somewhere between relieved and fond and discomforted all at once.

"So, first one, ana-" Sena almost swallowed his tongue, choking and gasping for air. Shin patted his back quickly.

"Sena?"

"Really? The first one?" Sena gasped, tears in his eyes as he gulped down air.

"It's alphabetical, Sena."

Sena dropped his face in both his hands, ignoring the paper crumpling against his cheek. He was too busy trying not to groan in humiliation.

"Sena, it's just anal. Doctors use that term," Shin said despairingly, snatching the paper back and smoothing it out again methodically. Sena let out a squeak muffled by his hands. "I take it that this is a no." He plucked a pen off Sena's nightstand to cross it out.

"What! No! I didn't say that!" Sena yelped, looking up and grasping Shin's wrist. Shin stared at him, bewildered, pen still hovering over the list. "It's just- It's kinda jumping into the deep end for me, okay? Just… let me re-adjust at bit." The runningback sighed, dropping his hand away. His eyes fluttered closed and he breathed deep to calm his racing heart. Shin narrowed his eyes down at him. He thought Sena would have some difficulty, but so quickly? And so much? He'd have to reschedule a bit in his mind to accommodate for this. Sena finally opened his eyes, jaw firmed, and gave Shin a nod.

"So, would you like to try anal penetration?" Shin asked bluntly. Sena flinched a little.

"Y-Yes. Eventually, I would. I… I know some gay couples don't, and it's totally fine, there's plenty to do. But… I'd like to try it. Would you?" Sena managed to answer relatively clearly.

Shin frowned down at the paper. "I am honestly not sure. There's a lot of preparation involved, not to mention hygiene issues. It's a lot of effort for something we might not enjoy," he pointed out astutely. Sena nodded, but still looked unconvinced, fingers twisting in the hem of his shirt.

"I get all that, but… I do… wanna… try…" his voice got steadily lower as he spoke.

"In what manner?" Sena frowned at the question, obviously not understanding. Shin tapped the paper. "One does the penetrating-"

"Oh my god, please stop using that word."

"And the other one is penetrated. Why can't I use that word?"

"It's just- use top or bottom," Sena begged almost desperately. Shin frowned, eyes squinting.

"I don't see how those terms capture the nuance of meaning necessary."

"It's a little simplistic, I get it, but it's just easier. Top for the… the doing part and bottom for the…t-taking p-part," Sena explained, stuttering and rushed. Shin's eyebrow raised.

"You wouldn't necessarily have to be on top to be penetr-"

"SO! I was thinking I could try the b-bottoming thing!" Sena interrupted shrilly. Shin blinked once.

"Really?"

Sena shuffled a bit and nodded, eyes downcast. "I know it's a little stereotypical, the 'littler guy' being bottom, but I just thought… maybe I'd l-like it," Sena confessed quietly. Shin glanced down at the list, face pensive. "We don't have to, though! It's just… I don't want to take it completely off the table?"

"In the interest of full experimentation, we'll take turns," Shin said decisively, making a note next to the entry. Sena gulped loudly, pupils dilating, as he swung around and stared at Shin. "If we don't like it either way, we'll just stop. But if it's something you know you're interested in, and I'm unsure but have no negative feelings about, then we should try it both ways."

"You would… you would bottom?" Sena asked incredulously. The linebacker shrugged.

"I'd try it. I don't put stock in stereotypes, Sena. I'm not going to only try one way because I'm the 'bigger' guy in this relationship," Shin replied frankly. Sena nodded, looking dazed and dumbfounded.

"The next one?" he prompted, swallowing hard past a suddenly dry throat.

"Asphyxiation," Shin stated in with a dark, heavy scowl. Sena blinked.

"What the what?"

"It's also called choking."

"EH?!" Sena snatched the list away and stared at the word, as if staring would give him answers to the tumble of questions in his mind. "Choking? People do that?! Why?"

"So you're not interested," Shin said with a relieved sigh.

"No, I don't like the idea of you almost killing me during sex!" He immediately turned beet-red saying the word aloud. "Why would people do that?" he hurriedly asked.

"Apparently it makes the orgasm better. I… I did not research it quite as thoroughly as I should have. I wasn't…I didn't find it appealing," Shin grumbled, crossing out the word with a quick jerk of his wrist.

"Agreed. What's next- biting? Oh." Sena's hand reach up to touch his neck, where the last bit of pinkish discoloration from a week before lingered. Shin felt his eyes follow the motion, stuck where Sena's thumb smoothed over the vestiges of the mark Shin had left behind. Their eyes met and Sena's smiled, secretive and bashful. "I think that's a yes. Can I… to you?"

"Yes," Shin agreed quickly, hoarsely. Sena looked away, blushing and biting down on his lip to keep from grinning. With a rough clearing of his throat, Shin dragged his attention back down to the list. "Bondage."

Sena started in shock. "B-Bondage?" He wet his lips with a swift flick of his tongue. "L-like, with ropes and stuff?"

"… yes, that's the more… experienced kind, however. The articles and blogs recommended using scarves, ties, or even handcuffs first. They include basic restraint sometimes, such as just using hands and natural strength."

As Shin carefully remembered his reading, Sena was already squirming. He knew how strong Shin was, he'd been pinned down and hefted up dozens of times. He still remembered their anniversary night with blazing clarity. It may have starred in several jerk-off fantasies, unsurprisingly. Sena liked that Shin was strong, was stronger than him, but always knew to keep things gentle off the field. But what if Shin could use that strength in the bedroom? Pinning Sena down, keeping him still and unable to move, totally at Shin's mercy? That… sounded really… really fun. Shin was so thorough, and he had so much more control than Sena did. And Sena trusted Shin more than he'd ever trusted anyone. They could… they could do something like that and it'd be fun.

"Yes." The word came out a little too breathy, his heart thudding in his throat and his hands gripping the loose fabric of his t-shirt over his belly, where something hot was twisting and burning. "I want that."

Shin easily checked it. "I don't see anything wrong with it, as long as we're careful. I don't know how much I'd like it done to me-"

"To me. I'd like you to do that to me," Sena clarified quickly, too quickly. It had Shin staring at him in surprise. "I'm fast, but you're the strong one. I like that you're stronger. I like that you… that you take care of me… when we…" Sena blushed brightly and rubbed the back of his neck. "I just trust you to do it right."

Shin's grip tightened around the pen in his hand. "We'll definitely try it."

Sena nodded, licking his lips again, then glanced towards the list. "Collars?" His head tilted to the side. "Like… pet collars?"

"They can be made and ordered specially for humans, I read," Shin said tonelessly, eyes still distant.

"I don't think I'd like feeling like a pet. I buy collars for cats. Though…" He narrowed his eyes on Shin's neck. "You could probably pull the look off."

Shin snorted loudly, finally breaking out of his reverie and crossing the item off. "I don't like the idea of being owned, or owning you."

"And if you wanna be all possessive, we've already okayed biting," Sena attempted to tease, smirk a little wobbly and cheeks pink. Shin shot him a look.

"Indeed." He looked down at the list and something like want flitted over his features before he carefully shuttered it away. "Coming untouched."

Sena blinked, his thoughts going again to last week, Shin shuddering over him, groaning into the damp curve of his throat. "I don't think we have a problem with that one," he said a little breathlessly.

"I'd like to try that with you."

Sena flushed up to his hairline. "O-okay. We could do that."

Shin nodded once and tapped the next one. "I don't understand the appeal of this one."

Leaning over to squint at it, Sena pressed a hand to his mouth to stifle giggles. "Really? You don't like the idea of crossdressing?" he asked, both amused and curious. "I thought every guy likes maid costumes or school girl uniforms."

Shin's mouth twisted into a grimace. "I've seen males in maid costumes. Ootawara in such a thing was not attractive at all."

Sena burst into laughter, doubling over and clutching at his stomach. "I totally forgot about that! Sakuraba-kun looked cute, though, right?" Sena wiped at his eyes and gasped painfully.

"If you say so."

"What about… um… l-l-lingerie? Some guys… they like wearing fancy lingerie stuff? Suzuna showed me a website that made it especially for men and threatened to buy me some for my birthday last year."

"Why?" Shin honestly looked perplexed at the idea. "Did she want to see you wear it for her?"

"What!? No! It was because she's Suzuna and she likes embarrassing me," Sena sighed, slumping a little. "But she also thought if I wore it I could… seduce you or something. It was back when I thought maybe you didn't want to… you know… ever."

"Ah. I don't think such tactics would have worked on me. If I wanted to be seduced, putting clothes on would not be the way to do it," Shin said nonchalantly.

Sena choked on air.

"The next one is docking. I… Is this something you want to try?" Shin asked, a little bewildered. Sena blinked, still coughing and panting for air.

"W-Whassat?"

Shin pointed to the word and the little handwritten blurb of an explanation. Sena promptly choked again. "Is th-that f-fun?"

"I have no idea, but research claims it so."

"I don't hate the idea of it?" Sena wheezed slowly.

"Maybe, then."

"People are weird. Who looked at… at that and thought, let's do this and see what happens? Who was the first person to try that?" Sena wondered aloud. Shin's mouth twitched.

"Someone with a fixation and a lot of curiosity."

Sena snort-chuckled helplessly. "What's the next one?"

"Speaking of fixations. Oral fixation was a term I found. I wrote it down… I… I don't think I have such fixation, but I like the idea of my mouth on you."

He really did. After trying his hand at oral last week, he couldn't get the idea of spending hours just practicing. Keeping his mouth on Sena's cock, feeling him soft in his mouth, getting harder, figuring out exactly where and how to get the best reactions, how deep could he get him down his throat. He liked Sena's fingers in his mouth, and the taste of his skin and juddery pulse on Shin's tongue. He liked feeling Sena come undone under his mouth.

"Y-yeah, I… I like it, too," Sena murmured, pulling Shin out of his musings.

He checked the item with something close to smugness.

"Orgasm Delay or Denial."

Sena squawked. "Denial!?"

"I liked the delay one. I like making you wait. You're too fast, want it too quickly. I like it when you wait for me to tell you to let go," Shin admitted. Sena pressed his hands to his red face.

"I think I'm boiling my brain today," he muttered to himself. "I'm going to stain my face permanently tomato-red."

"I don't think that's possible. Is that a no?"

"N-No. I mean, it's not a no? I… I like that, too. Like with the… with the restraining bondage stuff. I like… like you telling me… telling me what to do. I get so embarrassed and self-conscious," Sena was mumbling by this point, hands twisting his shirt in his hands so tightly the threads were creaking. "It's nice not having to be anxious or worried because I know I'm doing it right if you're telling me to do it. I don't like the denial part though. I want to… you know."

"But if I ask you to wait, you'd be okay with that?" Shin clarified, voice a little too low. Sena rapidly nodded, voiceless.

"Prostate Stimulation."

Sena wheezed. "That's an a-a-nal thing."

Shin had to fight down the insane surge of pride that Sena managed to finish saying 'anal'. "Yes, I know. We agreed to give that a try. This should be a maybe, too?"

"Y-yes. I… I don't where how to… find it…though?"

"It's not a subway system. I'm sure we'll figure it out."

Sena laughed helplessly, forehead knocking against Shin's shoulder.

"It should really help with the coming untouched. If we're sensitive enough, some men just don't enjoy it."

Sena nodded soundlessly, then placed his finger on the list. "Public sex, Seijuuro? Really? You would be okay with that?"

"Ah… no."

"What about... kinda public? Like… the bathroom at that restaurant? Where we might get caught, but probably not if we do it right… how was that?" Sena specified, keeping his face hidden against Shin's arm. Shin stared down at him.

"That's something you like."

Sena squeaked, knowing he was caught. "I…I may have… um… fantasized about… the locker rooms…" he mumbled, voice so muffled by Shin's arm that the older man almost couldn't make it out.

And well… Shin didn't put those things together. Football was football, his romantic relationship was separate. He couldn't merge them together because he and Sena were on opposing teams. He couldn't grey area his career and his relationship, they both deserved more respect than that.

But… Sena seemed really keen on the idea. And if it wasn't after a practice, or if it were after a game with another team… He remembered that kiss after the Rice Bowl. He remembered how hot his blood had been after his victory, how intense every caress had felt, magnified by a thousand with his blood still pounding so close to the surface, skin already feverish. Only Sena's less than joyful demeanor had cooled his ardor that night.

"We could… try that. I prefer not before a game, or if the game is us against each other."

"Yeah!" Sena yelped eagerly. He blushed brightly and quickly reined himself in. "Yeah, that'd be… let's try that sometime."

Shin was almost smiling as he looked back down at the list. The barely-there lift of his lips died a quick death, wiping away between one blink and the next. He hadn't wanted to write down this option.

"I don't like this one," he said firmly. Sena glanced over. A quickdrawn breath and his eyes widening were his first, involuntary reactions.

"No, I don't think I do, either. It's like the choking thing. I don't want to hurt you, or you to hurt me. Not like this, not even if it's pretend. I don't want to pretend to be scared of you, and I've never liked having power over anyone else. Definite no on that."

Shin gratefully crossed out rape-play/Noncon scenes.

"I thought… since you liked the bondage… you might…" For once, Shin was stumbling for words, looking uncomfortable and edgy. Sena reached out and placed his hand on Shin's wrist. His thumb swept over the knob of bone, soothing and gently.

"Sei, I would never ask you to do something you truly despise. This is for both of us. And that other stuff? I liked it because I trust you not to hurt me. You can pin me down or tie me up, but it's not about the pain. It's about putting myself in your control and knowing you'll take care of me. That? That's pretending you're really hurting me, that I'm scared of you. I could never be scared of you. Not since I was 15 and a weak little bullied kid with zero confidence. You gave me confidence. You never hurt people because you like to, and I know that. I've always known that."

Shin shoulders slumped and the expression he turned on Sena was overwhelming in affection and gratitude.

"I love you."

Sena smiled and ducked his head. "Jeez, Seijuuro. Anyone who actually knows you can tell you're a nice guy. You just look angry. C'mon, finish the list." He snuggled closer though, arm snaking in between Shin's side and arm to hug his bicep like a pillow. The soft huff of Shin's breath over Sena's hair had the shortie smiling. "Love you, too," he added quietly. Shin pressed a kiss to the crown of his head- the sappy sap of a cheeseball- and brought the list up to read.

"Rimming is the next one. I don't thi-"

Sena made a soft, quickly stifled noise.

"Sena?"

"I… I just… it always looked like they really enjoyed it…" Sena muttered.

"They? …are you talking about pornography?"

Sena 'eep'ed and slapped a hand to his face. "Yes, maybe."

"At least one of us watches it," Shin retorted wryly. His eyes traveled down to the item in question once more, features concerned. "I'm really worried about mouths anywhere near that area."

Sena burst into giggles, sagging against Shin's side and feeling almost drunk from light-headedness. One day, ONE DAY, talking about sex won't be this hard.

"There's stuff to do… to use… to keep it clean. But if it's really gross for you, it's okay. We don't have to."

"…is it in a lot of pornography?"

"It's in almost every one I've watched. It's pretty popular. Don't worry, though! It's fine! We don't have to!"

Shin frowned down at the list. "I'll watch some videos first. I need a better informed opinion."

"You're… you're going to watch porn… to get a better informed opinion on rimming?" Sena blurted in shock. Shin nodded as he wrote a note down. I honestly can't tell if I'm more turned on or confused by this…Sena thought to himself.

"Sca- no. No, Sena, please, no," Shin said suddenly, face serious and eyes pleading. "I can't do this." Sena blinked and looked down at the list.

"Oh my god, no!" Sena burst out, face white. The utter relief radiating off of Shin was palpable. He struck off the option with a vindictive little scratch.

"Somnophilia? Oh, like, sleeping se-" Sena broke off in the middle of his epiphany, words slamming into babbles.

"Sex, Sena." He sounded almost weary.

"This, um, I'm okay with this. Would you be okay with this?" Sena asked, ignoring Shin's huff.

"I prefer you awake."

Sena snorted painfully. "I wouldn't mind waking up to this," Sena tried again carefully.

Shin stared at him, brain whirring. "Ah. Yes." Whatever he'd thought up had him checking it a second later.

Should I be laughing or worried about that?

"Hm, sounding. I saw this mentioned but I don't think I understood the translations. This wasn't on the list I gave Takami. It turned up in some of the articles he'd printed for me, however."

"Ta-Takami-san s-saw this?!" Sena shrieked. Shin nodded.

"The librarians wouldn't help me. Could you look this up for verification?"

Sena grumbled under his breath, ears burning, but pulled up a search engine on his phone and dutifully typed it in. "Oh, look, a video!"

He hit play and they waited for it to load. A second later, their jaws dropped and both were blanched bone-white.

"Turn it off, Sena," Shin ordered brusquely, physically recoiling away from the screen.

"I am! I'm trying! The ads keeping popping up and- there! It's gone! Oh my god."

"Why would someone do that?" Shin demanded, horrified. Sena fishmouthed and shook his head, looking just as shaken.

"Just no. Scratch it out. No."

Shin quickly did so, movements wooden and jerky. "Temperature play."

"Like, hot versus cold?" Sena asked, grateful for the change in topic. So grateful. He was going to have nightmares over that video. Also, he was pretty sure his phone had a virus now. Crap.

"From what I saw, there was using ice and hot wax? Not hot enough it actually burns, though." Sena still grimaced at the idea.

"I… I don't think I'd like that. And not just because of the wax. Rubbing ice all over me doesn't sound fun. I hate being cold."

"I don't think I'd like this either."

"So, no. What's next?"

"Toys."

Sena immediately pictured a teddy bear, then his favorite action figures as a kid. Then, after rolling his eyes and reminding himself this is about sex, Sena, not those kinds of toys! he thought about it a bit more, biting his lip.

"Uh, yeah. There's some things I'd like to try. I'm just… I'm too embarrassed to go out and buy them. And I didn't want to order anything online to my parents' house or to my dormitory, you know?" Sena confessed with an awkward laugh. Shin nodded seriously.

"Some of them had a very strange appearance, but most I could see the appeal of. We could look for some together and you can order them to arrive here?"

Sena blushed, but couldn't help the grin spreading across his face. "Yeah, I'd like that. I might have a mini-heart attack during the actual looking part, but I'd like that."

Shin checked it, mouth twitching at the corner.

"Well, we've gotta be almost done. What's left?"

"Just two. Voyeurism and watersports." Shin's eye twitched over the last one.

"Water sports? That actually sounds fun," Sena said guilelessly picturing shower sex or even beach sex or something. Romantic and very sexy, in Sena's opinion. Shin always looked so good sweaty and damp. They'd already proven that wall sex wasn't a hardship, either. Shower sex was a huge favorite in the few erotica Suzuna had forced him to read.

Shin's noise of surprise and pain had Sena pulling out of his fantasies with a startled frown.

"Seijuuro?"

"S-Sena, what do you think… that means?" Shin asked, choking out the words.

"L-like… sh-showers or a p-pool or...?" Sena hesitantly replied, wondering just why Shin looked so betrayed. Shin dragged a hand over his face, sigh rough and long. "N-No?"

"No. Sena, it's… it's urine."

Sena gaped at him.

"Like… I pee on you?"

"Yes."

"No."

"Yes, that is what it means."

"No, I don't want that."

"Thank you."

"Why did you even put in on there?! Or the other one?" Sena demanded, aghast and utterly flummoxed.

"In the interests of full disclosure-"

"Seijurro, let me make this very clear," he forced Shin to meet his eyes. Very serious eyes. "I do not want to do what I do on the toilet on my bed. Literally or figuratively."

Shin looked away, hand over his mouth, shoulders shaking.

"WHY ARE YOU LAUGHING!? This is VERY serious, Seijuuro!"

"Y-yes, I know. I-I a-agree."

"You're laughing."

"It's n-nothing."

"Fine, we're done."

"You didn't say yes or no to the other one," Shin said, mouth still twitching at the corners as he turned back to Sena. Who was glaring at the opposite wall, arms crossed and blushing cheeks puffed slightly.

"I can't remember what it was."

"Voyeurism."

Sena blinked, offense sliding away as he rolled the term over in his head. "Voyeurism? Like… watching other people?"

"No, me watching you." Sena felt shiver run down his spine at that tone of Shin's voice. He couldn't bring himself to turn around, though, hands tightening into fists under his biceps. "We could do it the other way. But I know I like watching you."

"Y-yeah?"

"I always like watching you."

"That should be creepier than it is," Sena breathed out. His eyes slid shut as Shin placed calloused fingers to his jaw line, sliding over soft skin and making Sena shudder.

"Says the man who can't stop staring when I'm training without a shirt on," Shin pointed out, amusement clear in his tone. Sena bit his tongue. He had no idea Shin had noticed that. "I would like to sit back and watch you one day. I wouldn't even need to touch myself. I would just watch you."

"W-Would you-" Sena broke off, biting on his lip just shy of too painful, cheeks ruddy.

"Would I what?"

"W-Would you tell me what to do?" Sena whispered.

Shin's fingers went still and Sena heard his breath too loud in his ears. It thundered with his heartbeat and his hands dropped to his lap, curling into the loose, soft fabric of his sweats. He couldn't bring himself to look up yet. Not with the heat already surging in his stomach and the embarrassment lighting up his face.

So he didn't see the way Shin's eyes went dark. Or way his hand holding the list clenched convulsively, crumpling it in his fist thoughtlessly. Sena didn't see the way Shin's eyes scanned down his profile, lingering on his bitten-red bottom lip and white-knuckled hands.

"Would you do exactly as I told you?"

Sena jumped slightly, his heart jumping into his throat with him, belly twisting into coils.

"Y-yes."

"Right now?"

"Right now? Like, right now right now?" Sena repeated, eyes wide as he finally looked up. Shin's face, his intensity burning into Sena's astonished gaze, had that coiled heat burning. His mouth went dry at Shin's nod and he could already feel his cock jump in his pants. "Yes, right now."

Shin got up and walked towards the desk. The small confused noise that escaped Sena at the abrupt action had him blushing brightly, humiliated at the needy sound. But Shin didn't leave. He merely pulled out Sena's desk chair and sat down, legs a little wide and hands on his knees. The list was lying forgotten on the desk behind him.

"Take off your shirt."

Sena grabbed the hem, belly and groin hot at the low-pitched command. Gradually, he pulled the shirt up and over his head. It wasn't quite smooth, his nose getting caught and the sleeves catching around his elbows, but it dropped to the ground long, heavy seconds later. He licked his lips and looked over at Shin.

... [Sorry dudes, FADE TO BLACK HERE; TOO LAZY TO SMOOTHLY SEGUE]

Shin got to his feet, ignoring the twinge of discomfort of his half-hard dick in tight briefs, and bent over to press a kiss to Sena's forehead. The sweat there had gone cold, and it wasn't exactly a pleasant sensation on his lips, but the low, contented hum from Sena at the endearing gesture made it worth it.

"I'll run you a bath, too."

"You're too good to me," Sena sighed happily. Shin's expression was serious, even though his mouth had softened.

"Never."

Firstly, these are NOT my personal opinions of some of these kinks (most notably, I fucking love panty kink/crossdressing OOooo and collars!). These are my personal headcanons for how THESE TWO CHARACTERS would view these things. They are NOT MEANT TO BE KINK-SHAMING. I don't care what kinks y'all have. (Dudes, I'm from Sterek fandom. I've read xenophilia.) If it's done sane, safe, and consensual, then all to the good, have fun and fuck anybody else's shaming. Just remember, these boys are 1) basically virgins, or as I like to say, sex-newbs, 2) for different reasons, relatively uninformed of sexual things so these things are NEW AND SHOCKING to them (Sena admits to watching porn, but he doesn't watch it often, nor even has a variety, and Shin has only seen the occasional porn in the pursuit of RESEARCH, not to get off LOL), and 3) if you don't wanna be shamed for your kinks, the other way works, too; sometimes people are just not going to like things and there's NOTHING wrong with that either!

I'm terrible at dirty talking/praising apparently? I fucking love to read it, but nothing felt RIGHT when I tried to write it. It doesn't help that Shin ain't much of a talker, damn it. I think the actual sex part is good, but fuck words, y'all. (I just proofread, I think it's better than I thought during the process of? ehhhh?)

Lastly, there's a lot of POV switching and narrative written solely for humor's & ease's sake, rather than making any sort of attempt at artistic, well-written, or consistent prose. In other chapters, I would encourage and appreciate being called out on this so I can improve. But not for this chapter, please and thanks and I hope you enjoy.
