Ballbusting

My supposedly devoted foot slave has spent our entire evening out staring at other womens’ feet. I find his actions incredibly disrespectful and intend on punishing him for his poor attempts at self control.
He tries to apologise, but I won’t accept his pathetic attempts of apology. I tell him to get to his knees and look at my feet, as this is the last chance he will get. Whilst down there I instruct him to take off my beautiful strappy stilettos, and I tell him that I will be punishing him with my perfect petite feet to teach him a lesson about self control. I demand that my slave strips completely naked, as I remind him how I have had enough of his despicable behaviour. I tell him to start crawling up the stairs and before his knee touches the bottom step, I kick him viciously between his legs, landing my foot directly onto his balls. My anger apparent, I continue to land ruthless kicks to his balls as my sorry slave struggles up the first few steps of the stairs. He falters and stalls, so I grab his balls in my fist and squeeze; telling him that by the time I am done with his balls they will be completely destroyed. No one disrespects me like that- he should be staring at, and longing to worship my feet all night, not other peoples.
My slave tries to get away, I demand he turns around, back against the stairs so I can see his balls as I kick them. He begs for forgiveness, almost squeaking when my foot meets his balls repeatedly. After a brutal kicking up the stairs, he finally reaches the top; his balls look so kickable hung over the top step- so I tell him to lay down fully and I take pleasure in kicking them hard again and again. My slave anomalistically shouts into the carpet in response to each kick, struggling to keep his composure. His balls are trapped between each strike of my foot and the top step, with no escape I intend on ruining his testicles.
My disloyal slave thinks we are done, but I assure him we are only just getting started…
