Beach I
"Onii-chan! Onii-chan!" Gou called from afar. Rin was enjoying the warm sea water, as he let the waves carry his body in a relaxing journey. Upon hearing his sister calling him, he took a look at the shore where her voice came from. Gou was waving for him. And there was someone standing next to her. Orange hair, muscular body, and a flashy speedo. "What the hell is he doing here?!" Rin said to himself and cursed under his breath, then he swam towards the shore.
"What are you doing here, captain?" Rin asked with a glare.
"Just thought about inviting some of my cute underclassmen and club members to the beach and have some fun. And what a coincidence to find you here with Gou-kun!" Mikoshiba said with a wide smile that he flashed at Gou's direction.
"Oh, really?" Rin said as he walked to his things and grabbed the shirt he was wearing. Then he walked back to his companions, put the shirt on his confused sister and buttoned it up before turning to his captain and say "Let's have fun then, captain."
Mikoshiba cursed in agony and said "What fun is left now, Matsuoka?! What the hell is wrong with you?!Dammit!"
"What the hell is wrong with you! If your definition of fun is watching my sister in a bikini, then you should be thanking me for sparing your life, you broom-head, pervert, speedo-man!" Rin yelled back.
"Thanking you?! The whole world will thank me the moment I get rid of you, siscon! Why do you love crashing men's dreams that much?!"
"You're not even denying that you're a perv!"
"And you're not denying that you're a siscon!"
"Whatever! Gou, let's go ba-" Rin was saying when he turned back to find that his sister wasn't there anymore. She was already packing her things, but she spared a second to look at the direction of the two boys to say, "You're the worst. Thank you very much for ruining my day, you perverts."
