USBA-067 [Uncensored Leaked] Beautiful Girl Training: Childhood Friend and Unrequited Love Turns Her into a Sex Slave... Kokona Yuki

I stumbled upon Yuki's secret...! A masochistic girl who enjoys being brought to orgasm over and over! "On my way home from school, I unexpectedly ran into Yuki, my first love. After a pleasant conversation, Yuki said she was going a different way home. Suspicious... I secretly followed Yuki. Yuki entered an unfamiliar building. When I peeked inside, I saw Yuki undressing in front of an old man and shaking her hips... She was treated like a slave, and she got excited, being raped by the old man and brought to orgasm over and over. Seeing Yuki like that, I felt sad but also got an erection."
