Mistress Luna (2019) Tied Handjob – Ruined orgasm by My skilled hands

I control My slave sexuality! I own him and I own his cock. I keep him in chastity device and from time to time, I ruin his orgasm!
I don’t do it because I care about his pleasure, not at all! I do it from medical reasons : I want to have a healthy slave!
However, his orgasms are always ruined but, even so, My slave must pay for each gram of sperm I take out from his balls!
Must I mention how much I enjoy milking out My puppy?
I love to do it! To drain him out, taking his pleasure away and make him conscious about the fact that I own him and his sexuality!
