Forbidden I: Matsukawa Issei

Being Oikawa's younger sister mostly came with perks, most of his friends treated her with kindness and she soon became a part of the third year's group. With this Toru had made her promise that no matter what she wouldn't date one of his friends, when she was younger she saw no problem with that. Now being a seventeen-year-old girl, she had discovered how truly hot his friends were, especially Matsukawa. The certain middle blocker had quickly caught her attention as she entered high school with them. She couldn't put a finger on what quite made her seem to melt around him but it was becoming an increasing problem.

    "Mattsun let me go!" she turned her eyes toward the scene folding out in front of her. The two, third years had entered, with Oikawa thrown over the messy-haired middle blocker.

    "Then stop trying to skip practice." his words were spoken with ease, as the slightly shorter captain continued to struggle in the boy's arms. She began to laugh at their antics catching the attention of both of them, she didn't notice how he smiled.

    "[n/n]-chan! Don't laugh at your older brother!" His comment made her laugh more once she caught a glimpse of his panicked face. She caught herself on the bench nearby as he continued to yell across the gym causing more eyes to make their way to their captain. Most of them were surprised to hear the [h/c] haired girl to laugh, during practice she mostly had her head in a book and seemed rather bored. Leading most of them to be surprised to find that she was, in fact, their captain's little sister, they were way too different for some of them to fully accept it.

    "Then stop being something to laugh at Toru!" her usually soft voice echoed to the two boys making the taller one begin to laugh, almost dropping the setter. Her words made the other two, third years start to laugh as they emerged from the change room, they started cracking jokes at the setter's expense.

    "You all are so mean to me!" by this time Mattsun had let him down when he had almost dropped him a second time. They started to tease him about how sensitive he was until the coach had entered signalling the start of warm-ups. Mattsun and Oikawa had jogged towards the change room then joined in warmups once they had thrown on their gym clothes.

The practice was coming to a close when Mattsun had asked [y/n] to help him with something in the storage room. She made her way over to the small room, once she was in front of the door he poked his head out looking around them to make sure nobody was paying them any mind before she was pulled in by her wrist.

    She let out a quiet yelp before crashing softly into his chest, she heard the door close as he caged her against it. He lifted her chin with his finger catching her in a kiss. Her hands reached out finding their way to the collar of his jacket, deepening the kiss. They separated, leaning his forehead against hers leaving small kisses to her face.

    "I really missed you." Desperation was clear in his voice, she let out a small chuckle, sounding more like a shaky breath. It was true she had missed him too, due to finals coming up, the third years had mostly been holed up in the library together.

    "I missed you too, but this is really risky" despite her warning she leaned into his touch, he hummed as his kisses trailed down to her neck.

    "It wouldn't have to be if you came over more often."

    "I don't think Toru would like that."

He leaned back, meeting her eyes there was clear guilt in his eyes at the mention of his name. She brought her hand up to stroke his cheek, he leaned his head into her touch with his eyes closed. It was a topic they hated discussing, the main reason they were sneaking around. Toru had always been rather overprotective over her and had a few people that were completely off-limits for her to date. It had also been a topic of most of their arguments since as she got older and the relationship with the messy-haired boy had developed became more unreasonable to her.
