The challenge is simple: make the man cum from cowgirl within five minutes of penetration. This time, fair-skinned Shinohara Nagisa arrives in red lingerie. Practical with money but overflowing with lust, she notes that foreplay does not count toward the clock and prepares his cock with a blowjob, nipple licking, and a titjob. Then she mounts him and the countdown begins. She unleashes an unbroken rush of piston-like bouncing, spider, grinding, forward-and-back, side-to-side, front-leaning, and backward-arching cowgirl moves, expertly controlling her pussy without pulling off, cumming, or taking a break. After proving that cowgirl is not merely her specialty but her favorite, she refuses a reward and remounts him so she can ride exactly as she pleases. Even after draining him to the last drop, her relentless pussy still is not finished.
