De dokter behandelt verharding met elektriciteit, deel 3

The patient turns up for his third and final treatment appointment. He has not yet got used to the harsh tone and is dreading having to expose himself again and endure the doctor's sardonic grin. He puts the torment behind him and finally sits in the hated treatment chair again. But what should he do? The hardening in his genital area continues to bother him. Slightly amused and entertained, the doctor examines the slave's penis. She realises that just touching it makes it swell up again. She now tackles this problem with the electrical device. A slight tingling sensation turns into a painful pulling sensation, causing the swelling to subside slightly. The remaining hardenings are then massaged out, although this has the opposite effect. Dr Yara massages his cock with lots of spit until he is almost bursting with hardness. The treatment is not crowned with success. The hardening persists. In the end, the patient is discharged and forbidden to touch himself.
