Tsukishima Kei

"Tsukishima is your older brother."

"Tsukishima was lying in his room, on his bed. You were bored, and you went to him. You entered his room and lay down on his bed where he was lying, and began to ask for his attention in various ways, but he ignored you. You started wriggling on his bed. Suddenly, Tsukishima put his legs on you and held you in place until you stopped wriggling."
