I'm the younger brother of the dormitory mother at Seiyuri Hills Girls' Academy, and I'm the only man in this girls' dormitory. However, don't be jealous... Her older sister forces her to do chores, she is shunned by the students, and she is living a lackluster life. Furthermore, at night I was forced to take care of my older sister's sexual desires...Isn't there such a thing as a kind older sister somewhere?One night, when I was standing in the bathroom, I met Mahiru Sakuraya, who was always particularly cold to me, in the hallway!But she... She is unusually kind to me and for some reason tries to put me to bed...!?I can't keep up with this unexpected turn of events, but her crotch is honest and I react to Mahiru's big boobs that I see from a close distance!I touch her a little. I fired just by being hit. When Mahiru saw this, she said, ``Leave it to your sister,'' and gently wiped my dick and stuffed it into her mouth...!?
