Cockbox hủy hoại bootjob - edging shoeob

I'm trying out my new cockbox on my slave. It hinges and locks shut, keeping him in the perfect position to tease him with my sexy thigh high boots. He's been in chastity for 7 days, and is extremely horny. Lucky for him I decide to milk him, but not without some lots of edging first. Closer and closer I get him by rubbing his little spot under the bottoms of my boots. Until he gets not one, but two ruined orgasms. But still he came too fast for me. I wanted to play with him longer. Oh well. Back to chastity and better luck next week.
