[Umemaro 3D] Vol. 13 Semen Analysis

At a fertility clinic, nurse Chiha Rokuhato specializes in helping patients provide large semen samples. Patient Kenji Kataoka must fill a substantial collection cup. Chiha guides him through four progressive stages: oral or hand stimulation, titjob or thigh job, mutual masturbation, and finally full penetrative sex. Players choose specific acts and can switch to first-person POV perspectives with adjustable speeds. Archive footage from earlier titles is used as stimulation. The 2015 release improved the video loop system and remains popular for its clinical role-play and technical polish. Both standard and dedicated POV versions circulate.
