This time, the target "Mina" is tricked by a senior she admired in her student days and brought to a female body torture research institute. While saying "I don't feel anything!!" under the torment of the staff, her dick is rock hard. She continues to utter rebellious words with her mouth, but her body twitches and convulses, and it's clear that she's feeling a lot. In the end, unable to bear it, she repeats "I'm going crazy! I'm going to go crazy!!" and cums like crazy!!
