An amateur man's penis diary. Vol.6 Subaru-kun, a college student who loves to show off and calls himself a sadist but suffers from premature ejaculation (20) GRMO-334

Hasumi's hobby is documenting her sexual encounters with men. She enjoys driving lecherous men to the brink of masochism, deliberately feigning vulnerability and pretending to be able to seduce a young, handsome Subaru at a bar and then take him home! Using her mature techniques, she makes him anxious, teases, and berates him, revealing that he actually suffers from premature ejaculation, subjecting him to the agony of holding back ejaculation multiple times, and manipulating him through ejaculation control♪
