Deep Throat Slave Who Loves Cock Sucking: Only Had One Partner, But Has Jerked Off Over 300 Cocks with Her Mouth. The Blowjob Genius, Plain Jane Science Girl Mari (20) Who's the JAV actress in this video? Amateur? Name revealed!

A female engineering student from a Tokyo university makes her appearance. This science-minded girl is obsessed with blowjobs and deep-throat (with reverse ejaculation), having taken over 300 cocks in her throat, driven by an insatiable craving for extreme pleasure. Fully aware of her masochistic nature, she's a genuine pervert who craves the choking, near-vomiting sensation of intense deep-throating. From the moment of first meeting, public humiliation play begins, leading to brutal outdoor training where she's tormented with relentless deep-throating until drooling and gagging. Her suffering continues in private, where she writhes in agony with teary eyes, climaxing uncontrollably in pain. Finally, she's made to perform an extreme finish—cleaning every cock in the group with her mouth in the bathroom.
