Chastity Cage Milked to Cum in Condom

It’s milking time but I refuse to unlock my sub’s chastity cage. Instead, I slip a condom over the cage to catch the mess and apply my wand vibrator to the outside of his cage. He watches a POV video of me getting face-fucked as I torment him – the extra visual pushes him over the edge. He ends up **cumming inside the condom while still caged**, his orgasm totally constrained. I then unwrap the cum-filled condom around his cage and keep vibrating his swollen, locked cock to see if I can force any more out. A merciless draining with zero pleasure for him.
