Spread Eagle Tease - Ruined After 31 Edges

It's been 2 weeks since slaves last milking. So today I feel he deserves to let a little bit of cum out. But it's not going to be as easy or enjoyable as he may hope.. Strapped down spread eagle and exposed- I start his very slow and gentle edging. Making sure I don't let him cum right away.. Very agonizing and frustrating.. I love putting him in this predicament.. 31 edges is enough to finally make him suffer a ruined orgasm, before giving him some port orgasm torment. I wonder how many more edgings I can do next time..
