You Belong to Me, Senpai

Summary:

Notes:

Hehehe, I love possessive Reno.

Work Text:

Narumi Gen had always been the popular student around the college. Despite his trouble-making upbringing, he was exceptionally smarter than the rest of his peers. He was the person everyone would go to if they were in trouble, but only some of them were actually able to find him. It wasn’t because he didn’t want to help, but because some of them were only using him. Still, Gen was popular and he was aware of it. However, he wasn’t aware of one thing.

His own boyfriend, Reno, hated the fact he was so popular and Gen was oblivious of this. Today too, he saw Gen being surrounded by a bunch of girls from his class. Since they both were in the fashion design major, it became a sight that Reno had to get used to even though he didn’t want it. Every time, even now, he could feel his anger were boiling.

‘How come he never notices me?!’ Reno grumpily thought to himself, watching as Gen started to walk toward his table. He knew Gen was giving him the concerned stare, yet he didn’t bother himself to hide his hatred.

“Reno? You good? Did you not sleep again?” Gen worriedly asked him, but his hand was being slapped away when he tried to touch Reno. “What’s your deal?!”

“Why don’t you chat more with those girls? Surely one of them would appreciate your touch.” Reno scoffed. “The Popular Narumi paying attention to them, yeah that sounds great.”

“You do know they have big project, right? They just asked me for advice, no need to be so snarky geez…” Gen was pouting. “Besides, you have the biggest advantage. I mean I get to supervise your project all the time, then we get to cuddle and—”

Gen bit on Reno’s ear, whimpering right next to him.

“—you get to fuck me stupid after that.”

Reno’s face turned beet red from that. He tried to catch Gen as the older student ran away, sticking out his tongue in a mockery way. He could only let out a heavy sigh, then laughed as it was too funny. Not because Gen kept teasing him, but because how he let himself being played by Gen. Two could play that kind of game, but Reno would take extra measure to make sure his boyfriend would stay obedient to him.

Gen only belonged to him, so he’d make sure everyone knew that.

 


 

Gen’s class ended earlier than the schedule due to his professor had some business to attend, so he had been waiting for Reno at the park bench near their class’s building. As usual, he was soon busy with the girls surrounding him. He did his best to answer their question regarding the lesson or giving them suggestion on what game to try, being friendly because he loved being popular. Gen was so caught up in the conversation that he failed to notice someone.

Reno was approaching him, then he poked his back with a bottle of tea with only half of drink remained. There was nothing alarming from him, as he was still smiling like the usual. However, it was something when his smile alone managed to make the girls that had been surrounding Gen suddenly disappeared.

And Gen? He was still smiling at Reno, unaware of the danger emitting from his boyfriend.

“Oh hey! Can we go back now? I want to try the new game already,” Gen took the tea from Reno’s hand, chugging it down in one go, “ew, this taste weird. Did you put more water in it or is it expired already?”

“Sure, but we have to go buy some groceries first ‘kay?”

Before Gen could argue, Reno already dragged him back to their car. He remembered that they just did grocery shopping three days ago, so it was still too soon for them to do that again. They did run out of fruits a bit sooner and forgot some stuff as well, so maybe it was just to fill the gaps in their kitchen. At least, that was what Gen thought.

The grocery shopping took longer than Gen expected. It shouldn’t have to be a problem; however, it was different now as it bothered him. He was getting more and more uncomfortable the longer they walked around the shop, tugging on his over-sized t-shirt with his left hand while his right was clinging onto Reno’s arms. Glancing at his boyfriend, it pissed him off because Reno looked so much more relaxed.

“Reno…,” Gen whimpered, leaning against Reno for support, “can we go now?”

“Sush, I still need something, senpai.” Reno was being a bit too dilly dally for Gen’s liking, but of course the younger one didn’t care about the fact his own boyfriend was trembling as he clung to him. In fact, it was the opposite; Reno loved the way Gen looked right now.

Gen’s frustration became even more obvious. Before he could even utter a single complaint, his legs were shaking a bit too violent. He muffled his voice by biting on Reno’s shoulder, feeling some liquid staining his black cargo pants. He leaned closer to Reno’s ear, letting out heavy breath right next to it.

“Reno please….”

That was it for Reno. He was satisfied enough, thus putting their shopping session to an end. Well, he had to rush back home so he could properly take care of his boyfriend after all. Surely no one wanted to see him wreck Gen in a way that would tarnish both their reputation. He drove back home as fast as he could, torturing himself on the way by listening to Gen’s finger deep inside his pussy, trying to get some relief. He could only watch it from the mirror, licking his own lips by watching the way Gen’s back arched as he laid on the back seat, fingering himself.

The car was being parked a bit too recklessly in the garage, so lucky Reno for not getting the car scratched. Not that Reno care about that, because he immediately dragged Gen into the house. They didn’t even need to reach their shared bedroom, as Reno threw Gen on the couch in the living room. His lips were immediately on Gen’s, cutting the older one’s oxygen supply with a hungry kiss while his hands busy removing their clothing.

T-shirt? Now ripped off.

Pants? Scattered near the door along with the stuff they got from the shop.

“Reno please, it feels weird—!” Gen wailed. He gripped the couch’s arm tightly, head tilting backward when Reno’s mouth latched on his left nipple. “Aaahh! Not there!”

“Then where do you want me, hun?” Reno chuckled. He kept his fingers playing with Gen’s clit, pinching and rubbing that small bundle of nerves. “Be more specific ‘kay? Like when you teach those fans of yours~”

“Fuck! You little shit!” Gen whined, finally grasping the entire situation with his brain. This was Reno’s way of punishing him, drugging the drink he had earlier with aphrodisiac. He didn’t know how much his boyfriend put in there, but surely it was enough to drove both of them insane. “How did you—?!”

“How? Patience, duh. After all,” Reno’s lips moved to the crook of Gen’s neck, biting hard until he left a dark purplish mark on his skin, “my boyfriend is the bigger shit who refuse to listen to me.”

Oh, Gen could feel Reno became even rougher with his fingers. Four fingers deep inside his cunt, messing it up until Gen turned into a babbling mess. Any attempt to form a thought was gone, cease to exist, leaving a crying mess in the form of Narumi Gen. It wasn’t long until he started to feel another orgasm was about to come out, making his feet curl in the air while his hands were gripping Reno’s hair.

“Are you close?” Reno chuckled as he bit Gen’s earlobe, whispering to him, “—then fucking cum for me, slut.”

“A-AAAH! RENO! RENOOO!!”

How pleasant for Reno, to feel Gen writhed underneath him and heard him scream his name as he came. He immediately removed his fingers, replacing them with his mouth. He was licking and biting Gen’s clit, driving the poor senior into madness and overstimulation. He didn’t mind having Gen gripping his hair so tightly, loving the way hearing him beg for him to stop.

There was no such thing as stopping, not when Reno’s cock was fully hard.

“Wait, please wait… sensitive, too much!” Gen whimpered upon feeling Reno’s cock on his cunt, rubbing it roughly. “Please Reno, please! I need— umpfh!?”

Reno didn’t give Gen the chance to speak by covering his mouth with his hand. He put his dick in in one go, loving the way Gen’s body twitched at what he did. Watching his boyfriend losing his mind like this was better than any movies.

“I know what you need, senpai,” said Reno as he gave a hard thrust, hitting Gen’s g-spot dead on, “so just relax, okay? Use your brain only for studying, not when I’m deep inside you—”

Thrust.

“—fucking you like some cheap slut in Kabukicho,” said Reno, thrusting some more until Gen gave him a hasty nod. “That’s my pretty boy. I bet you wish for one of the girls to fuck you like this, hm?”

“Ah… hah…” Gen gasped for air, shaking his head to answer Reno’s mockery question.

“Words Gen, I need your word.”

“Noooo! Don’t want to be touched by them!” Gen whined, fucking himself back on Reno’s cock. “Reno…! Reno only! I’m sorry, hng! I won’t ignore you again!”

Satisfied, Reno kissed Gen’s forehead as reward. “That’s my boyfriend. As a reward, I’m going to fill you up so good.”

There was no more time being wasted, with Reno immediately pounding into Gen with lust and hunger. He was pounding into him without caring about anything, only getting more excited to watch Gen’s eyes rolled back as he lost his ability to form coherent words. He was just laying on the couch, being pretty and stupid, spreading his legs wide enough so Reno could breed him.

Breed, filling him up with his cum.

Neither of them could hold on for any longer due to the effect of the aphrodisiac. Gen came first, squirting on Reno’s cock. Reno followed soon enough, filling Gen’s cunt with his cum. They both took a moment to savor this feeling, staring at each other’s eyes with anticipation.

It was still far from over.

 


 

“Renooo~”

“Stay still Gen, I’m not done yet with your pussy— ah!”

They both moved to their bedroom. Gen’s body being folded in half, legs on his chest as Reno kept pounding into his over-filled cunt. The squelching sound resonated in the room, making both of them felt even more eager to fuck each other.

Reno kept fucking like madman, while Gen laid there like pretty princess whose job was only to scream loudly. The younger man was filled with pride, happy to be able to see his loved one scream so loud, letting the world know how the two of them were so in love. However, he wasn’t happy to see that Gen was about to faint. He gave him a hard slap, bringing him back to reality.

“Oh… ah! Mngh! Reno! Renoooo!!” Gen wailed weakly, clutching on Reno’s shoulders. “So full… so full! I can’t—”

“You can, because I—”

Reno kept pounding on Gen’s g-spot, then he stopped abruptly as he reached his orgasm once again. He could feel his cock spurting out cum, filling up Gen even more.

“—am going to shape your cunt to fit my dick.”

Reno pulled out, loving the way he made a mess of Gen’s body. He watched the way Gen’s legs dangling off the bed, with cum slowly dripping out of his abused cunt. He scraped the overflowing cum, shoving it back inside of Gen and watched the way Gen winched upon being filled with his fingers.

“I’m still not done yet, love. I still have to teach you not to become an attention seeker, so be ready ‘kay?”
