Wakashi Lab Vol.2 "The Female Spy Is Used as a Test Subject for Tickling Devices." KOTORI is subjected to hellish foot sole torture, eventually breaking and revealing her secrets. Used as a test subject with the interrogator's various tickling devices, she remains captured. Overwhelmed by the unfamiliar sensations, she loses her composure as a spy and shows her true, unfiltered reactions. When a lotion brush touches the soles of her feet, she erupts into screams and violent thrashing unlike anything she's ever experienced. Yet the torment doesn't end at the interrogator's whim. The tickling experiments continue until she has fully internalized the secrets she confessed.
