SSIS-397 Riri Nanatsumori, a month of shared living ends in dense copulation after abstinence

Riri Nanatsumori and a man live together for a month without masturbation or sex, spending each day in foreplay that stops just short of orgasm. When the abstinence period ends, they go at each other immediately and keep going until neither can move. Their desire builds from the core and they greet each other like animals, with Nanatsumori turning into a beast. The session is so intense they are left wanting more.
