My favorite big-breasted, idiotic childhood friend is being used as an SM toy by a perverted brat. Chiba Yuka CAWD-982

I have a childhood friend named Yuka. We went to the same school, were in the same class, and went to and from school together. Yuka has always been clumsy; she still falls and exposes her underwear, or spills water from the tap, soaking her shirt. But as she's grown up, I've gradually started to see Yuka as a woman. Then… I saw Yuka being taken to the warehouse by some bad kids. I rushed after them and found her being raped by two men. Watching her bouncy, natural G-cup breasts sway as her mouth and vagina were violated by penises, I didn't have the courage to help her. I could only masturbate while hiding and watching. Afterwards, even when I was restrained in the bathroom, being deep-throated and breast-spanked, I secretly masturbated, feeling regretful and annoyed. One day, while in the classroom with the bad kids, she was raped again. When I tried to stop them, Yuka offered to give me oral sex. Although I was surprised, it felt good, and I, who suffers from premature ejaculation, immediately ejaculated. Feeling utterly devastated, watching helplessly as she was violated was probably the most agonizing moment of my life, past and future… But I made up my mind. I had to save Yuka… In the warehouse, I tried to save Yuka with a bamboo sword, but the clumsy Yuka fell, and I was powerless to stop her, becoming nothing more than a sex slave. I couldn't do anything. Damn it, let's run away, Yuka. But, for some reason, Yuka also craved SM play and felt happy. Huh? Why? She was being violently and greedily violated, her mouth and vagina soaked with semen, while she was reaching ecstasy. Ah, at that moment, I also ejaculated by masturbating. This is a teenage story implanted with extremely perverse fetishes.
