The story of a girl who was a sex slave and found her worth only in making men ejaculate, but slowly transforms into a woman as she lives with someone and experiences kindness. One day, I found a girl being sold as a sex slave on the street. Out of pity and a desire to help, I bought her. She, who had only lived for sex, relentlessly pressured me to ejaculate. While I didn't want that, I couldn't refuse her advances, and my body... was honest. Every time she pressured me, I'd get an erection and ejaculate, and it's pathetic, but I spent my days being drained of my semen until there was none left.
