We let busty girls who applied for an undercover investigation sneak into a massage parlor (guru) and secretly film the whole thing! The women were doing their investigation seriously, but they fell prey to the aphrodisiac and erotic massage and said, "I don't want to, but I can feel it!" Their whole bodies became sensitive and they orgasmed from their nipples with expressions of agony! They squirted from a fingering massage! ... They couldn't hold back any longer and begged for penetration, and they went wild with sex! What was the result of the investigation...?
