When I let my slave out of chastity for "a little fun", he knows he's in for a painful, traumatic experience, but he's so desperate and horny that his cock can't help but jump to attention the moment I free it from the steel chastity device.
I get him nice and overstimulated with a cock pump before slipping on my razor-sharp vampire gloves, digging the spikes into his desperate dick, stroking him with the grating metal spikes as he screams and begs for it to stop.
He's left in pain and in even more sexually frustrated than before as I lock him back up.
