Serious and studious female student Narumi. Her beautiful girl figure is one that everyone envies. One day, on a whim, she starts engaging in paid dating through an app. After taking an aphrodisiac for the first time, her body becomes extremely sensitive, convulsing uncontrollably with rolled-back eyes whenever her neck is choked. Day after day, she continues returning to men. Her pussy is used recklessly like a fleshlight, repeatedly creampie fucked even on her fertile days, steadily transforming her into a full-fledged cumdump.
