In the clinic, the poor patient receives sadistic treatment from the two nurses on the subject of orgasm. Absolutely defenceless, the poor patient is tied up on the medical couch. First his "penis" is thoroughly cleaned from the inside with dilators of different sizes, then a very mean teasing with air control begins. It goes without saying that the patient can only control himself with the utmost effort and yes, he may really can shoot his load, but unfortunately under certain circumstances the meaner could not be.
