Slave's Cock Edged and Milked to Ruined Orgasm

I've been training my slave to eat my pussy exactly how i like it. i ride his face until i cum hard, my sweet juices dripping down his throat. he's completely helpless, strapped into the spreader bar and i reward him by cruelly edging him and milking his throbbing cock until he explodes. i did not give him permission to cum, so i of course have to punish him for his transgression. he gets slapped in the balls until he begs for mercy.
