Mao Asakura (麻倉 真央)

Futa club's chairman. She's a meer xx-years old, and she has skipped several years to enter the academy. Before Akane joined the club, she always had problems because of her immense size, and was never able to satisfy herself. When she gets an erection, she becomes anemic, and that is when the true chairman awakens.

Both her size and her ejaculation volume are exceptional. She can release an immense amount of cum with a single stroke.
