Using an ovulation-inducing agent to induce estrus in horses, riding on a horse-shaped penis, and using a carriage-piston riding position to rock her hips, the female employee Fujii Ranran was penetrated daily. (FNS-195)

A female employee who looked down on men who were too engrossed in horse racing to concentrate on their work. She became the target of the man's revenge. The man prepared a "horse ovulation inducer," a substance effective on horses ten times the weight of humans, so it couldn't possibly be ineffective on humans. The female employee, after drinking coffee mixed with the inducer, became more aroused than the man had imagined. She mounted him without permission, vigorously thrusting her hips in a riding position. Because it was unprotected, she didn't care. She used semen to swell her vagina, engaging in intense riding. Even the trainer stamped his approval, saying, "This is a top-tier breeding mare."
