The target is mother-daughter pairs visiting the library! Caught in bold molestation acts, they panic and flee through the building, only to be captured and groped all over their bodies, involuntarily showing sensitive reactions. Both mother and daughter end up accidentally urinating. As erect cocks rub against them, they writhe in extreme humiliation, exposed to each other's view, unable to endure the pleasure of grinding. Eventually penetration is allowed—mothers climax repeatedly as women, forgetting even their daughters. In front of them, the daughters, confused by the unfamiliar cocks, orgasm again and again. A total of three pairs—six mother-daughter victims—are simultaneously ensnared in grinding and lewd molestation, becoming prey all at once!
