Yaoi one shots n'stuff

Rin Matsuoka x shy!reader

You were a quiet person. Never really spoke much. Not necessarily because you were shy but because you didn't really feel like wasting your breath so whenever you said something it was always important. When you first met Rin when you joined the swimming team he was easily infuriated by your seeming disinterested personality but you had shocked him. One day you had walked into the pool and seen him pushing himself too hard. You had been swimming for almost your whole life and you loved the water (not as much as Haru but a lot in your own way) and you actually wanted to be a professional surfer when you got older. You joined the swimming club because there was no surfing club so it was the next best thing.

So when Rin's legs suddenly got a vicious cramp in the middle of a lap and you immediately threw yourself into the water to help him out, despite still being in your clothes, he was shocked. He didn't think you were the kind of person to do that. But you had dragged him out of the water and gently patted his back as he coughed up water. Afterwards you had spoken to him for the first time since introducing yourself by simply stating your name. You had told him not to push himself. He was already amazing and he didn't need to keep over working himself. 'Don't stop, but make sure you know your limits so when you test them you have someone to pull you back when they need to.' 

Rin gradually warmed up to you after that. You didn't mind though. You enjoyed his company. The two of you would swim together, eat together, where one was so was the other. So when you two finally started going out it was no surprise to the swim team. You two had been walking around on a date together when you ran into the Iwatobi team. It was in an aquarium, with your face nearly squished against the glass and your eyes sparkling though your face remained relatively neutral and your soft purple hair messily falling in your eyes  that you had met the team. Or more specifically, Haruka Nanasa. Rin had walked out of the bathroom to see you and Haru standing next to each other seeming to have a silent conversation about the water through various nods and glances towards the water. He was instantly jealous and had stormed over as the Iwatobi cried out in surprise to seeing him as he wrapped an arm possessively around your waist and glared at Haru. "Yo," 

Haru nodded at him and turned to you and nodded at you, looking at you slightly longer before turning and walking off, leaving the Iwatobi team to confusedly run after him. Rin growled after them. he didn't like how Haru had looked at you. he was brought back to reality as he felt something soft and warm press against his cheek for only a moment before the warmth left his side. Rin's eyes widened as he realized you had kissed his cheek and he turned to you for an explanation and was shocked to see your eyes laughing and the corners of your mouth twitching slightly. You were mocking him. Rin growled but couldn't help the grin that tugged at his lips as he walked over to you, backing you against the glass of the aquarium as his arms rose to either side of your head, trapping you in. "You knew I was jealous," he growled. Your lips twitched again and Rin growled crushing his lips against yours. Rin's tongue hungrily pried open your lips and pushed its way inside your mouth, claiming the familiar territory with ease.  You were a cocky little prick and you could always easily tell when he was jealous so you loved to make him jealous. 

Rin pretty much knew you did it on purpose sometimes but he didn't mind. It just meant he had an extra reason to kiss you and he didn't mind that one bit. There was a cough and Rin reluctantly broke this kiss, grinning at your red face as you panted to catch your breath. Rin looked over his shoulder and gave a sharp glare to the aquarium attendant behind him, effectively scaring him away. You softly hit his shoulder and Rin gave a sharky grin, pressing his lips to yours one more time before pushing off of the glass and grabbing your hand, smirking as you walked closely next to him with your face towards the ground trying to cover your blush.
