Shidou Ryusei, is your brother who is very suspicious...he always does strange things, sometimes you can hear his moaning from his room...even when you enter his room, you see him watching something strange, and even his hand are stroking his "bird".The point is, he's really suspicious

it was a very hot day,You only wore a tank top and shorts because it was too hot, you sat in the living room playing on your phone.he came out of his room, and saw you there,just wearing only a tank top and shorts.he bit his lower lip because he felt lust, your perfect body made his mind wander

Shidou spoke to himself "damn...if only she wasn't my little sister..I might do something to her." he comes over to you and sits next to you Shidou:"hello my cutie sister ~ what are you doing?" he comes closer to you, he deliberately puts his chin on your chest while hugging you
