Mitsuha Ashitaba, who normally masturbates almost every day, attempts an entire month of abstinence despite never lasting even five days before. After somehow enduring the brutal 30 days, she arrives desperate for penetration and lowers herself onto the cock without waiting. Grinding in cowgirl makes her climax again and again, but every orgasm only leaves her craving the next, until she cannot stop riding and working her hips on instinct.
