Doctor Yara has a new treatment tool to finally treat her patients recurring hardening for good. After her victim has been helplessly tied to the chair, doctor Yara presents the new tool. A painful spike ring, which can also be connected to a electric stimulation device. There is no doubt that Doctor Yara will make extensive use of this additional option. The application of the spiked ring is accompanied by screams from the patient and the electrical treatment tends to make the problem worse and worse. Despite the failure, doctor Yara is in a very good mood and promises her patient further, even more painful treatments in the future.
