The Club

Yū's p.o.v
I can't believe my little sister is here, at an all boys school nonetheless. I'm gonna have to protect her from every male at this school, and I dread when the 'Photography Club' sees her. Toono will be allowed to go near her as he isn't physically attracted to girls, but I'm not so sure about the others. Tamura and Ayato better behave around her or else I'm gonna hit them where it hurts. Those two are the ones I worry most about going even remotely close to Y/N.

As I see my little sister jumping out of the car and into my arms, it finally sets in, my baby sister is attending Mori Mori Academy. I look down at her uniform, at how snug the blouse is and how the skirt stops about mid-thigh. I have this sudden sense that makes me so aware of our surroundings and it dawns upon me on how perverted and horny the students are/can get. I quickly push that thought out of my mind as I feel like I'm struggling for breath and the cold sensation one feels when in contact with metal. Ah yes, Y/N's famous bear hugs. I look at her cheery face and greet her
" Welcome to Mori Mori, lil sis". She looks up at me with that bright smile of hers that could melt even the coldest of hearts. I nod to dad, signalling that it's ok and he can go since I am here to keep an eye on her. He returned the nod and drove off to work. I asked Y/N to follow me into the main building and down the corridors. Everything was going smoothly, until we were about to pass the club room and my fellow members were entering the room. They saw me and then their eyes drift down to Y/N, her body and then her arm. Oh crap.
