Disclaimer: I do not own any of these characters. I’m also not making any money off of this fanfiction.
Freez: I’ve wanted to do a story about these two for a long time, never really had the right motivation until I had a dream, which always seems to be the starting point of any fanfiction I start, lol. I really like this pairing and the anime, and have read almost every highly favorited fanfic on this site related to it, lol.
Let me know if you guys like it or not?
It’s going to be either 2 or 3 chapters long, maybe more if you guys like it, idk, up to you.
Warnings: Rated M for a reason and there will be kinkyness, I’m famous for it at this point. It’s a Yukio/Rin, I’m pretty sure… My dream didn’t get that far so the more ppl who review and want Y/R will get their wish but if enough want R/Y, I will do that instead.

I honestly haven’t seen many R/Y out there so I don’t know if anyone will actually ask for that or not?
AFF: Story was moved here because a guest reviewer told me no MA stories on FF. Yeah, tell that to the 2 million other people who write SMUT on that site...

Rin Okumura lay on his bed with his hands behind his head. He was relaxing before Yukio got home and made him work on his homework and study. His tail thumped at his side. It would rise up before falling down, over and over.
He had long ago realized that his new appendage had a mind of its own. The furry thing when loose gave away any emotions that he was feeling. If he was sad, it dragged on the ground, loosing all its spunk. If he was mad, it would sway around, lashing out at anything close to it. If he was happy, it tended to wag, which embarrassed Rin and pissed him off to no end.
When Rin was aroused though, that’s when the fun happens with his tail. His tail REALLY had a mind of its own when he became aroused. He recalled back to the first time he pleased himself after gaining the new appendage:
Rin sighed, opening the door to his and Yukio’s room, dropping his bag and grabbing a change of clothes. Yukio had pushed them hard that day in training. He was sweaty and felt gross. He had also stayed after class to walk Seime home and talk to her. They both knew she could just use the key but she had insisted that a walk would be nice.
He’d enjoyed his talk with Seime, which wasn’t anything out of the ordinary as they mostly just talked about school and their mutual friends, but Rin had wanted to get home and wind down.
Rin began his heavy trudge to the bath, eager to soak in the hot water and just relax.
He didn’t even notice the other clothes in the basket when he tossed his in, nor the dirty clothes in the hamper as he dropped his own in. He drabbed a towel off the rack and draped it over his arm.
He pulled open the sliding door, taking a step in to the bath, and stopped dead when he saw Yukio.
The younger brother was sitting on a stool, turned away from his older brother; a small bucket of water over his head before he tipped it and let it was all of the soap from his hair.
Rin watched attentively as a clump of soap slid down Yukio’s back and in-between the two mounds, which looked oddly plump and attractive as Yukio sat, and nested there.
Rin’s eye’s widened, realizing his body temperature was rising steadily as he watched the water slide down his younger’s brother’s back. He could see the lean muscles ripple as Yukio dipped the bucket and repeated the process once more. His brother’s body was something that Rin considered to be perfect.
Yukio shook his head, shaking the water from his dark brown tresses, and placed the bucket down. While Yukio shook his head, Rin had been entranced by Yukio’s butt cheeks as they jiggled, feeling the heat on his face and throughout his body turn into a full fledged inferno. The heat was pooling in his groin, fiving life to his dick as it began to fill and become stiff. Rin gulped and grit his teeth, trying to will away his bodies reaction, but it didn’t seem to help.
His tail was twitching wildly, rubbing against the back of his legs and sending shivers up his spine. He didn’t notice the light groan escape his lips at the sensation until Yukio’s back went ridged.
When Yukio began to turn towards Rin, the older moved his left hand, which had the towel draped over it, to the front of his form, effectively hiding his pulsating erection.
Yukio gave a surprised look when his lucid green eyes met the intense blues of his older brothers before his eyes turned more curious.
“Nii-san, are you alright?” He stood up, walking towards Rin quickly, which only made the older blush and jump, his tail standing straight in the air and ridged.
“I-I’m fine! I just didn’t know you were already in the bath! Sorry, Yukio, for barging in on you.” Rin meekly rubbed at the back of his head. His smile was wide enough so his eyes closed as he tried to not look at his younger brother’s penis.
“Are you sure?” Came Yukio’s quizzical reply as he studied him intently. “You made a pained noise.”
I’m really fine! I’m just tired from the long day is all!” As Rin waved his right hand in dismissal, he didn’t notice that his left hand holding the towel swayed, making the bulge hiding behind it noticeable for just the briefest of moments. Yukio’s eyes didn’t miss the movement. Rin was too busy smiling and not opening his eyes for fear of staring at his brother to notice the faint blush and surprised look on Yukio’s face.
Yukio brushed past Rin, quickly grabbing a towel and wrapping it around his waist before turning his head to look back at his older brother.
“Hurry in the bath so that I can help you study for the upcoming test.” He said sternly and walked away, grabbing his clean clothes from the basket next to the door, and going to their room to get changed.
Once Yukio was out of sight, Rin let out a sigh. He was finally able to relax. He placed his towel on a rack and slowly lowered himself into the hot bath, looking absently mindedly towards the stool that Yukio had been sitting on.
He looked down through the slightly murky water, from the bath minerals, to his aching member. His tail had resumed stroking his legs once he had relaxed. As Rin felt all the tension ease from his muscles, his tail had begun to move up his legs slowly, making him sigh at the pleasant fluffy feeling. He wasn’t too surprised but did blush when the fluffy appendage wrapped around his erection, stroking it with the wisps of the soft fur.
Rin tried to will his tail away, but it didn’t seem to want to listen to him and instead wrapped more securely around his member and flicked the tip. He groaned, jerking at the touch, and felt his tail tighten before rubbing up and down on his shaft.
Rin relaxed into the feeling and ran his hands down his chest, stopping to pinch as his perked nipples, reveling in the sensations that spread across his skin. He let his head tilt back to the edge of the bath and closed his eyes, focusing solely on the pleasure before the image of Yukio’s flaccid member came into his minds eye. We wondered how large Yukio got when hard. He imagined it, standing to attention in front of his face, and how he would worship it with his tongue. He would lick along the base slowly, looking up into his brother’s lustful green eyes, before sucking at the tip.
Rin’s face darkened, wondering what kind of pleasant noises would spill from his brothers soft looking pink lips. ‘Nii-san…’ Rin imagined him saying, in a voice that could barely contain his need. Rin’s tail worked faster as heat pooled in his groin.
Rin put his hand down to grab his member but his tail smacked it away before resuming its ministrations. Rin growled low before instead sliding down his side and going under his member to his ass. He pressed at the hole, probing slowly, before braking past the muscle and moaning loudly.
He scooted to the side of the tub and turned enough that he could reach behind himself better and pushed in deeper. He was searching for the one spot that would help him finish faster, knowing that Yukio was waiting upstairs for him, and jolted when he brushed it. His vision went white for a moment as he screamed in ecstasy before finger fucking himself in that same spot.
Everything for Rin was now just a haze of pleasure as he neared his climax. Rin could feel the drool that escaped his open mouth as he panted and moaned drip down his chin onto the side of the bath. And with one strong push of his finger, while his tail tightened around his member, Rin came harder then he ever had before.
Rin moaned, turning to his side. Maybe it wasn’t such a good idea to be thinking about things like that while waiting for his brother to get home.
