[Hisakawa Tinn] The art club has a problem (COMIC ExE 20)

A timid first-year joins her school's art club only to discover its oldest tradition: stripping bare as a nude model while the male members sketch every curve of her small breasts and soft thighs. What starts as innocent figure drawing spirals into a full harem free-for-all, her virgin pussy getting stretched around cock while her bespectacled senpai sucks off the director beside her, everyone moaning that liberation of the body is true art. Months later the club proudly counts two bikini-clad members among its ranks, though the director already laments that female members never seem to last.
