Sakura Kojima has been getting hornier by the day, and this test reveals just how sensitive she is. She masturbates first, then inserts a vibrator and nears climax—only for a real bare cock to suddenly replace it. A few thrusts make her tremble and cum immediately, leaving her hypersensitive. From then on, even the slightest movement of the cock sends her into violent spasms and another orgasm, over and over until she nearly blacks out from pleasure.
