A Hands-On Lesson

Summary:

He had a few reservations about going to a stranger’s house— but could he really call Kuya a stranger? He saw him everyday, and it’s not like Rei didn’t know him either…

--
Garu takes shelter from the rain at his teacher's place and ends up learning some new things about his body.

Notes:

This was written for Kuyaru month for the prompts "Groom" and maybe "Teach". But most definitely "Groom" lmao.
This fic takes place in the same universe as Curious Kisses. Not required reading, but it's where all the Rei/Garu mentions stem from!

(See the end of the work for more notes.)

Work Text:

Garu whined as he looked out the window at the dark sky. Just ten minutes earlier, it was all but clear— only for storm clouds to quickly roll in, heavy rain and wind following soon after.

Earlier, he’d been hanging out with Eiden, chowing down on all sorts of grilled meats as Eiden added more to their hot plate. Now, after the sky opened up on his way to the train, he found himself soaked and taking shelter in some clothing store.

Looking around, it was hard not to feel completely out of place. The clothes hanging around the store were probably worth more than Garu’s whole closet..! The shop attendants were kind enough not to throw him out— but he felt a bit silly pretending to browse, as if he could afford anything.

He nervously glanced at his phone as time passed. He’d long missed his train, and the rain wasn’t letting up. The next train wasn’t for another hour, so maybe he should call Rei? But— it was really bad outside. It didn’t seem safe to have him travel so far…

Just as he had gone to make a call, a familiar voice reached his ears.    

“And what are you doing here sneaking around the aisles, pup?”

Garu spun around, facing the man with a large smile.

“M-Mister Kuya!”

That sly voice and pet name were instantly recognizable (Well, Eiden told him he should feel more offended about it—). He was shocked to find his teacher in such a place, but the familiar face alone made him feel less anxious. Kuya’s eyes trailed down the boy’s body before assessing the situation.

“Caught in the rain, were we? How unlucky.”

Garu’s head hung low. “Yeah…I’m just waiting for the rain to stop now.”

Kuya hummed, touching his chin in thought. “..It would be best to actually check the weather. The rain won’t end for another two hours.”

Garu’s shock must have been obvious, because Kuya chuckled at him, just as if he’d served him one of his infamous pop quizzes. With that timeframe, that meant Garu wouldn’t make it home for another three hours, as the train only ran hour by hour. As Garu began to rack his brain again, Kuya gave a suggestion.

“You have nowhere to go, do you? I suppose I wouldn’t mind sheltering you until the storm rolls over.”

“Oh! Do you live around here, Mister Kuya?” Garu had always known the area to be on the “higher-end” side, and it certainly fit Kuya. The older man nodded.

“Come on then. The sooner we get back, the better.”

Garu hesitated before following Kuya as he turned to walk towards the exit. He had a few reservations about going to a stranger’s house— but could he really call Kuya a stranger? He saw him everyday, and it’s not like Rei didn’t know him either…

That little feeling only grew as he sat himself down in the passenger seat of Kuya’s sleek and modern car. That kind of luxury was deeply foreign to him, and he felt even more awkward knowing he was soaking the seat. 

Of course, Kuya didn’t get to the car unscathed either, but he looked a lot better than Garu. The umbrella held off most of the rain, but Garu couldn’t help following a drop down his exposed chest, his mostly unbuttoned shirt not doing much to cover him.  

When raising his eyes though, he was met with his teacher’s mismatched gaze, clearly caught in the act. Kuya smirked at him, before Garu turned away, suddenly taking an interest in fiddling with his seatbelt.

Garu tried keeping his gaze ahead, occasionally feeling eyes on him as they slowly made their way to their destination.

 


 

If Garu felt out of place at the clothing store, then he didn’t have words to describe how he felt as the door shut behind him in Kuya’s apartment. It certainly wasn’t as minimalist as the decor of that store— strange trinkets and boxes displayed all over— but there was still an air of luxury to the place he wasn’t used to.

—And at least the store had other people in it, no matter how few there were..! Garu felt a bit shy being at the center of Kuya’s attention.

Garu jumped when Kuya suddenly placed his hand on his shoulder.

“Let's get you out of those clothes.”

Flustered, Garu nodded in response. The combination of cool air from the apartment and his wet clothes weren’t very pleasant— not even mentioning his hardening nipples uncomfortably rubbing against the cloth of his shirt.

He let Kuya guide him deeper into the apartment, the man’s hand gripping his shoulder the entire time. It turns out Kuya was leading him to the bathroom, the place being just as elegant as the rest of his space.

Kuya finally let go of him as he went to gather towels and arrange some fancy looking bottles. A large angled mirror stretched atop of the equally sized vanity below it. It was so wide, Garu could see the entire bathroom in it.

Distracted as he ran his fingers over the smooth wooden finish of the counter, he jumped when he looked up to the mirror again, seeing that Kuya was right behind him.

“Uh— Hello!” He blurted out. Kuya humored him with a smile.

“Hello. Planning to shower clothed?”

Garu blinked dumbly at Kuya through the mirror, struggling to find a way to phrase his words.

“Well, no! But…” Kuya’s expression remained unchanged, making Garu’s voice grow quieter. “It’s just— If you’re…”

“Hm?”

Kuya stepped closer, nearly flush with Garu’s back. That soft, lavender smell he only ever caught whiffs of at school suddenly enveloped him, making it hard to think. He was quickly shocked out of his haze, though, as he felt the hem of his shirt being grabbed.

Mister Kuya!? What are you—”

“You seem like you need some help.” Kuya interrupted, lifting the boy’s shirt up casually.

Garu suddenly remembered how to move as he felt the wet top pull just above his belly button, his hands flying to the older man’s in an attempt to pull his shirt back down.

“W-Wait! I can— Wah!?

Kuya ignored the boy's words, easily overpowering him and pulling his shirt up above his chest. Garu stopped struggling, paralyzed by the sight in the mirror. His chest and pebbled nipples were on full display, and the knowledge that he and his teacher shared a view made him glow red in embarrassment.

“M-Mister Kuya, why are you…” Garu gasped, as Kuya's hands moved to grope at his pecs. He weakly tried to pull the man's hands down once more.

“Don’t play dumb now, pup.” Kuya pinched at the boy’s nipples, making his back arch. “So eagerly following me home like that…is this not what you wanted?”  

Garu squirmed under the man’s touch, trying to collect his words.

“I wasn’t thinking like that at all, I just— Ah—!”

Kuya gave another tug at his nipples, then moved to roll the hardened nubs between his fingers. Garu struggled to hold in his moans due to the continued attention. He tried wriggling out of the older man’s grasp once more, but was pushed closer against the counter top. Kuya chuckled behind him.

“Such a dishonest boy. Should I stop then?”

Garu made a confused noise as his nipples were released, the sudden loss of stimulation being…disappointing, to say the least. Without thinking, he pushed his chest out.

The two met each other's gaze in the mirror. Garu sucked in a breath as Kuya spoke in his ear.

“See? This body of yours can’t help but tell the truth, But—” Kuya’s hands trailed down to the boy’s soaked shorts, earning a yelp as he suddenly pulled down, removing the shorts and his underwear.

Garu whimpered at his new view, shirt hiked up over his chest and his hard little cock now fully exposed to himself and Kuya. The man took Garu’s hands in his, pinning them to the counter in front of them, ensuring the boy couldn’t give himself any relief. Garu gasped as Kuya ground his clothed, hard cock against his bare ass.  

“—If you can be honest with me, I might consider giving you what you want.”

Tears of frustration began to well in the boy’s eyes. He really didn’t expect anything to happen, but at the same time, he really wanted Kuya to touch him again. Garu had hardly considered such a thing before, but now it was all he could think of.

“I-I wanted you to touch me…” He murmured, avoiding Kuya’s eyes. He whined when the man laughed in response. 

Touch you? So eager to get fucked, but you can’t even say the word?”

Garu chewed at his lip for a moment before finally working up the courage to squeak out his words.

“I wanted you to— to..fuck…me…”

Garu’s face burned with shame and embarrassment as his sentence petered out. Kuya seemed satisfied, flashing a fanged grin.

“I suppose that’s good enough.” Garu felt a wave of relief as Kuya released his hands, but grew confused as he watched him move to unbuckle his own belt.

“But Mister Kuya, I thought—”

“I did say might, pup. You were still dishonest, which warrants some form of punishment..” Garu gulped as he suddenly felt something long and hot poke at his ass. “You should be grateful I’m allowing you to touch yourself at all— any more complaints and I might not be so kind.”

Garu kept his mouth shut, not wanting to lose the one privilege he had already. Kuya reached around him to grab one of the bottles he had earlier, flicking the cap up and pouring the contents out onto his bottom. Garu jumped as the cold, sticky liquid hit his skin.

He moaned softly as Kuya began to massage it into the plush skin of his ass. Garu couldn’t see his own ass in the mirror, but he could see Kuya’s satisfied expression as he felt his cheeks spread open, his rim completely exposed to the man behind him. 

He glanced at his forgotten cock, now practically dripping. As he took himself in hand, he set a quick pace, unable to take his time when he’d been denied for so long.

Behind him, Kuya slid his own cock between the boy’s cheeks, squeezing the soft flesh around himself.

Mmh..See? And to think you tried to act so innocently earlier.” Kuya cooed, beginning to thrust himself in and out of the plush mounds.

Garu moaned wantonly, pushing back against the slick slide of his teacher’s hot cock. It was overwhelming— the wet, hot feeling continually sliding across his hole. The lewd squelch from the slide of Kuya’s cock made the boy shiver.

Garu’s eyes blinked open for a moment, catching a glimpse of himself in the mirror. He feverishly worked at his cock, tongue hanging out as he gave up trying to contain his sounds.

Seeing himself like that— he couldn't help but think that Kuya had a point. Would he really have settled so easily into this situation if he didn't want something from Kuya?

Did his body always look like this? Was this what Kuya saw…? Every glance Kuya had ever thrown his way in class flashed through Garu's mind. The thought excited him.

He was pulled from his thoughts as he suddenly felt the tip of Kuya’s cock slip against his rim.

“A-Ah!?”

Garu stiffened at the contact, a strange tingle jolting down to his toes. Kuya must have noticed, because he licked his lips as he looked down. He deliberately pressed his tip against him once more.

Uh— Mister Kuya? What are you—”

“Is this not what you wanted? Did you not ask to be fucked?” He rubbed his tip in circles, making Garu squirm.

“W-Wait, it feels weird…!” He tried to pull away from the sensation, but Kuya just pulled his hips back. The older man chuckled darkly before pressing more firmly against the boy.

“Oh really..?” Uncaring of the boy’s protests, Kuya pushed further, threatening to slip inside.

“Mister Kuya— Please— WaiAaah!

Garu shook as Kuya just barely slipped past his rim, his little cock bobbing as cum shot from it. Garu had to steady himself on the counter, still reeling from his intense orgasm. He managed to catch a glimpse of Kuya, a dark look in his eyes before he pulled back, taking himself in hand.

He finished himself off with a deep groan, spilling all over his cleft. Garu couldn’t help raising his hips up to meet the warm spray of cum.

Kuya was the first to speak after a moment of silence, speaking as if he’d been completely unaffected.

“Now, let’s get cleaned up, shall we?”

 


  

Garu sat on the couch next to Kuya, absentmindedly watching some game show on the large TV.

After what had been the most tense shower of his life— (Kuya had insisted on getting in as well, caking the boy in all sorts of bathing products.) Kuya had put his clothes in the dryer and given him a robe to wear.

After seeing all the missed messages on his phone, Garu had realized he’d never gotten the chance to message Rei about the situation. Kuya offered to call him instead. He seemed overly amused about relaying the information.

Sitting around Kuya’s home after the earlier events was..awkward, to say the least. He squirmed under the older man’s gaze, and every accidental touch felt electric. Was that what Kuya meant when he said his body couldn’t help telling the truth? He still didn’t fully understand, and was nearly frying his brain trying to figure it out.

“Something on your mind, pup?” Kuya inquired, snapping the boy back to reality.

“Oh! Um— I was actually wondering..” He shifted uncomfortably as Kuya placed all attention onto him once more. “—What you meant about my body telling the truth?” Kuya scrutinized him for a moment longer before answering.

“It just means your body is more honest than that mouth of yours sometimes.” Kuya moved closer into his space. “Would you say what we did earlier was ‘bad’?”

Garu hesitated before coming to a conclusion, avoiding the man’s eyes.

“Sort of, yeah. I shouldn’t be doing that sort of thing with an adult.”

This adult, anyway, he had to remind himself, after memories of Rei popped into his head. Besides, Rei was different, and they’d hardly done anything like what Kuya had just done to him. Even Rei seemed to understand it wasn’t totally alright— likely to deny Garu even if he did want more.

“Then explain this to me,” Kuya reached out to Garu, catching his chin in his hand. “If it was so bad, why didn’t you stop me? You could have kicked, cried, screamed…”

Kuya gave him a moment to respond, but Garu struggled to, the older man rubbing his thumb over his bottom lip. After uselessly stammering for a while longer Kuya put him out of his misery, pressing his lips against his.

Garu tensed at first, but returned the kiss. He whimpered as Kuya swept his tongue over his bottom lip before pressing it inside his mouth. Garu tried to reciprocate, but was eventually overwhelmed by the older man’s skill. All he could do was clutch at Kuya, listening to his own choked out sounds. The older man finally pulled back, giving him some air.

“Even when you say otherwise, your body tells me all I need to know, pup.” Kuya snuck a hand into the boy’s robe, ghosting his finger over a nipple. Just like Kuya said, Garu’s body shivered at the contact.

“How lewd..You should be careful, who knows who else you’ve managed to tempt with this body of yours.”

The boy grew red and turned away. No one had ever spoken about his body like that, but he struggled to say he disliked it. Kuya looked down at him with amusement.

“Maybe you already have? That certainly didn’t seem like your first kiss.” Kuya inquired.

“Well, yeah. It wasn’t..”

Oh?  Who had the honor then?”

Garu sat frozen. Letting Kuya know that the honor of his first kiss— and many more—  went to his older brother was…probably not the best idea. Although even Garu had to wonder if Kuya could be scandalized by such a thing.

“...It’s a secret”

Kuya smirked at the answer, making Garu worry about him pressing further. Thankfully he didn’t, but he did lean back into Garu, whispering in his ear.

“Well, if you ever want to do more than just kiss, feel free to ask.”

Garu’s mind began to run at the idea of Kuya offering him a ‘next time’, wondering what more he could possibly have in store. As quick as Kuya was to get close though, he pulled back once more.

“The storm is letting up. You should go change, your brother will likely be here soon.”

Garu wondered how Kuya could know such a thing— but sure enough, only twenty minutes after he’d gotten his clothes back on, there was a loud knock at the door.

Kuya opened the door to a disgruntled Rei, whose expression only soured even more as he saw Kuya’s choice of clothes, still in his loose purple robe. Hoping to break the tension growing in the room, Garu ran between the two.

“Thanks for coming to pick me up! Sorry I missed the train..”

Rei’s expression softened instantly, a hand coming up to pet the boy’s head.

“It’s alright— let’s get home.”

Rei seemed in a rush to get out of Kuya’s space, but Garu didn’t question it. Rei and Kuya were always at eachothers throats, and he’d rather not see a fight break out. He’d had enough excitement for the day.

“Goodbye to you too. And—” Kuya turned his gaze to Garu. “It was nice having such a well behaved little guest. I’ll see you in class pup.”

“T-Thank you, Mister Kuya. See you!” Once again, Garu felt his face heat up, he hoped the tips of his ears weren’t red. Kuya laughed at him, of course.

He was glad he tied his jacket around his waist, feeling his cock harden— many memories stirred by that laugh and smile.

…Garu hoped that he could figure out how to manage his newfound lewdness before his after school lessons with Kuya. At this rate, his grade would never go up..!

Notes:

Glad to finally pluck this brainworm out my mind...I say as if my mind isn't constantly passing Garu between Rei and Kuya like a blunt. It was nice to write a very creepy Kuya again though. Until next time..🐺🦊💖
