In the history of the abstinence series, this is the toughest cohabitation between a man and a woman! Not being able to masturbate or have sex for a month is tough enough, but every day they have to foreplay and masturbate until they're about to cum, and they end up tormented by this abstinence torture! They want to cum, but they can't, and they're on the verge of reaching their limits of lust... The moment their abstinence time ends, they have sex and cum instantly... It feels so good that they can't move for a while. "It's not enough..." Their sexual desire wells up from the depths of their bodies, and they go crazy and devour each other in this intense sex! Riri Nanatsumori becomes a beast.
