Hikaru (23) is a lively and cute nurse working in an internal medicine clinic. Constantly handling penises as part of her job, she naturally becomes aroused when encountering a virgin's sensitive cock. Aiming to cure premature ejaculation, she diligently trains him with devoted handjob, blowjob, and grinding. Her warmth and meticulous care gradually heighten his sensitivity, evolving from vaginal twitches to intense clamps. Finally, she deflowers him with creampie sex, as the angel in white bares herself completely.
