The CBT stimulation test continues as Dr. Samantha tests her patient's reaction to her ball wacker toy. Apparently the thuddy strikes are too much as he can't achieve an erection. Dr. Samantha moves on to the stingy slapper, hitting his cock and balls as he struggles to take the pain. The last test is a metal ball crusher, which in combination with squeezing his cock achieves the desired erection. Dr. Samantha informs him that they will now move on to nipple therapy in the next clip.
