Bondage and Chastity Dynamics

My domme girlfriend keeps me locked in my CB 6000 around the clock. Right now I’m allowing myself just one orgasm each month, and that will soon drop to once every two months. She takes it out periodically so she can shave my cock and balls smooth as required. To stop me from grabbing my manhood, she handcuffs and ropes me up. Once her grooming is finished, she lets me stay out of the cage for a while, but those cuffs and rope remain until I’m secured again. It’s been nearly six months since I last touched myself. On top of that, I am being cuckolded; she heads out several nights weekly with a lesbian friend who knows exactly what’s going on. She teases me about possibly becoming her keyholder so we’d have two women dominating over me.
