Turned into a Bottom 1: My Boy Pussy's Just for Him

The mother of our protagonist, Yuzuki, introduces him to her new husband-to-be, Seiji Nagamuro. Yuzuki hoped his mom would be happy now, but instead, he got taken advantage of by Seiji on the first day of their marriage. After that, the three of them started living together under one roof, but whenever Yuzuki's mom was out, Seiji would have his way with him. Then, in a major turn of events, Yuzuki's mother and Seiji got divorced. Yuzuki wanted to leave with his mother, but Seiji threatened him with videos of their sexual relations, forcing Yuzuki to stay. With Yuzuki's mom out of the picture, Seiji was now free to use Yuzuki whenever he pleased. Enduring the humiliation, Yuzuki waited for his chance to escape. While servicing Seiji as usual, Yuzuki tries to butter him up with sweet words. "My pussy belongs to you father. I'd die without your cock." Satisfied to hear that, Seiji responds… "I'll make you my woman." He ties up Yuzuki's cock and fucks him to his limit. As Yuzuki screams for help, declaring his hatred for his new father, Seiji makes a suggestion. "If you can withstand my cock for 30 minutes, I'll let you go. However, if I make you dry orgasm, you're my woman for the rest of your life." Although he can't trust Seiji, Yuzuki sees this as his chance to escape and accepts the offer. And so begins Yuzuki's ruthless dicking. Who will win this competition? Will Yuzuki become Seiji's woman? What future will Yuzuki choose for himself...?
