A friend’s older sister gently rubbing with her stockinged feet

Hey everyone, I found a pervert! Lately,
my socks and stockings that I wore have been disappearing,
and turns out it was that pervert doing it.
How should I punish him?
He seems to get excited just by looking at my feet,
maybe I should give him a hard time…
No, I can’t take it anymore. I’m gonna step on him!
