Overview

"Sex is prohibited until you get married!!" Shiho, who adhered to his father's strict conditions and finally married his first love Masaki after many years of unrequited love and pure dating. On their wedding night, Masaki went to the bedroom nervously anticipating what was to come. That was when the formerly cool and distant Shiho turned into a lusty animal, kissing Masaki as if trying to devour her. "Do you know how long I've been holding back?" In one night, she was penetrated over and over again as he poured into her. She was happy to feel so good, but it's like being with a total stranger! A sweet, erotic newlywed life where love and desire explode! (Source: Printemps Shuppan, translated)
