Mistress Luna Ruined Handjob – Milking dry My mummy

I made My slave as a mummy, using foil and tape – he is totally helpless at My will!
I keep him in a chastity and now, I want to milk him but not too fast and not without making him pay for this!
I collect his sperm in a condom because I want to measure it.
Because pleasure is not grant it to him, he must pay for each gram of his cum.
How he will pay? – this you will see in a next clip!
