A haughty female employee looks down on her coworker for his obsession with horse racing, but she soon becomes the target of his twisted revenge. He spikes her coffee with a potent horse aphrodisiac, triggering an uncontrollable, animalistic heat. Completely losing her inhibitions, she straddles him and rides him with relentless intensity, begging to be filled to the brim. As she's drenched in his seed, she proves to be the ultimate 'breeding mare,' unable to get enough of the raw, unbridled action.










This work consists of four chapters, with sex scenes in chapters 1, 3, and 4. Given the title's references to 'horse ovulation stimulants,' 'horse-like cock,' and 'draft horse piston,' one expects intense action, and indeed, there is plenty of vigorous activity in the office. Yet, it just doesn't do it for me. I don't know why. While it's billed as a drama, the narrative elements are weak and the tone is flat; it feels like a generic sex-focused project. The male co-star is a muscular, high-stamina type to match the title, but he doesn't seem well-suited for dramatic roles. Perhaps that's why it falls flat? This is her fifth release since returning from a six-month hiatus, and like the previous four, there are very few kiss scenes. Specifically, only one per chapter in 1, 2, and 3, and while there are a few in chapter 4, the camera angles are poor or they are long shots. This is definitely a factor. In modern AV, frequent kissing is the norm, but this work—and her recent ones—seem to be going in the opposite direction. Looking back, her 'An Mitsumi' era was full of deep, erotic kisses using her long tongue; it's a shame that's gone. I wonder when I'll finally be able to title a review 'I am on cloud nine'.
