This video features a woman named Hibiki (pseudonym), who met her master, Mr. Honmyoji (also pseudonym) through SM submission magazine "Maniac Club". It showcases their seven-year relationship where she vowed to be his exclusive anal sex slave, even though she was still a virgin. On her birthday, she experienced an extremely humiliating and degrading event when a stranger at an adult shop inserted a grotesque dildo into her tight anus for the first time. The video includes various scenes such as counting down to the harrowing experience, the actual deflowering, post-deflowering activities, different types of anal play, forced oral servitude, announcement of losing her virginity, ignoring the submissive female, daily life of a sex slave, humiliating threesome, anal sex, electric shock torture, and a personal letter from Hibiki herself. Please note that this is amateur SM content created by enthusiasts and may not appeal to those seeking more traditional AV performances or storylines.
