An office lady who seduces her boss into enjoying rolling cowgirl lesbian sex, a perverted teacher who imposes masturbation bans on students and straddles them with wide-open legs, anal masturbation on a rodeo machine, and repeated threesome fuck sessions with constant partner switching—this is a relentless series of cowgirl-position orgasms. Enslaved by the pleasure of being on top, she can't stop thrusting her hips over and over again. The only thing that excites her is looking down at men who seem both pleasured and pained, and each time, her lust grows stronger. This work stands out with its intense eroticism, vividly conveying a woman driven mad by the joy of riding.
