ハーレムビッチハウス！（Harem Bitch House!）

Rikuto, who came to the share house as an acting caretaker through his cousin, is welcomed by Arisa, a junior gal who has come to live with him. He is welcomed by his classmate, Kanade, who is a neat and tidy girl, and Sumika, who is a senior and has a great deal of charm.

Rikuto, a virgin, is about to masturbate in his room when he is hit by the pheromones of a female overflowing from their big-butch bitch bodies, when Arisa appears!

"Do you want me to make you feel better while we're getting to know each other?”

Rikuto is pushed down on the bed and ejaculates before he can hold back from Arisa's expert blowjob.

"If I cum this quickly, I'll end up being disillusioned when I have sex with someone I actually like!" He blurts this out from shock, and Arisa makes a suggestion.

"The reason for premature ejaculation is that you don't have enough experience in sex,” she suggested. If that's the case, then why don't you have sex with experienced bitches all the time and train to improve?”

Sex training by bitch girls start!

Kanade and Sumika, the bitches who live in the share house and are just as sexually active as Arisa, join in this sex training program and train Rikuto in mind and body by having sex with him.

Not only in the share house, but also outdoors in the school, karaoke box, parks, cosplay, teasing, stopping just short of orgasm, and all kinds of erotic situations and plays, the sex-loving big titty bitch girls use their seductive bodies for intimate training!

Will Rikuto be able to grow up to be the strong, muscular, and mature man he desires with the special training he receives from these girls?
