Sumika Oohashi

Sumika Oohashi a founding member of Futa Club and the current Vice Chairman. She is in charge for all club activities, such as field trips, despite Mao being the chairman.

Appearance and Personality
Sumika is known to be the tallest and a leader of the Futa Club. She has purple eyes, with long dark purple hair reaching down her back, and wears glasses. Her outfit consists of a standard Japanese school girl uniform with a blue bow but without the brown jacket.

Sumika has strong sexual urges as seen in the second episode where she drugs Mao, putting her into a sexual frenzy (of note the drugging did not occur in the doujin). However, she often supervises Mao when she enters this state, as seen in the first episode when Sumika intervenes as Mao and Akane have sex to prevent Mao from injuring Akane.

Sumika is quite intelligent, able to read English as seen in the fourth episode of Futabu.

Penis Information
Sumika's penis length is nearly the size of Mao's, being only three centimeters shorter, being 40 cm (15 in) when fully erect. Her penis is also quite thin as well, compared to Mao's and Aya's, being at 6 cm (2 inches) in diameter and its gland is 4 millimeters.

Her penis is showed to be quite flexible, which she uses to perform different sexual acts for the club members. In the Hentai, she has been seen masturbating by auto-fellatio and in the concept art she is flexible enough to masturbate using her feet. When Sumika's penis is soft she sometimes keeps her penis tucked away inside her own vagina due to it's flaccid length.

Although Sumika's amounts of semen are the smallest in the club, she gets around this by not masturbating and allowing her to accumulate a lot of semen. It is first seen in episode 2 having sex with Mao, Sumika gathered semen for 3 days to ejaculate inside Mao, and in the last episode Sumika says that she collected semen from the day she left for the training camp a week ago. Also if Sumika gets more aroused she can ejaculate more quick cock shots, this can be seen in episode 2 when Sumiko has sex with Mao and Akane. As soon as Mao ejaculates into Sumika, Sumika begins to ejaculate constantly, quickly and several times. Sumika also seems to be able to exceed her normal amount of semen if she gets more and more aroused but does not ejaculate too often. This can be seen in episode 3 when Sumika has sex with Chie, Sumika manages to ejaculate long enough to turn Chie's abdomen into a bulge.

Trivia
