Sissy Extreme Chastity Tease

*** UNIQUE CHASTITY! *** Cock piercing locks to piercing behind balls, locking cock in a downward position making an erection painful & impossible. My sissy comes into the clinic to have her transformation monitored. We discuss male urges & I unveil my reasoning for piercing that is now healed. I bring out a lock & key explaining to my sissy that arousal will become so painful I will now gain complete control over all male urges. I lock his/her cock to a ring between the scrotum & anus (perineum) then sensually tease him to demonstrate how painful erections will now be. This is a very sexy tease & denial vid with extreme chastity.
