Big-breasted honor student who has become so lewd that he learns so much erotic things during summer vacation that he can live stream sex

Suzu is a normal, serious girl who seems to be everywhere. Suzu's parents end up on a trip for about a month. Meanwhile, his cousin Jun, who lives in the countryside, takes advantage of summer vacation to live in a vacant room in Zuzu's house for summer courses for university entrance exams. Thus began a strange half-living life for a month of summer vacation, but after a summer, a busty honor student who was a beginner at streaming transforms into an incredibly lewd bitch. #YoroP
