I delight in my slave's torment! Especially when stepping all over his balls with my barefeet and crushing them with my toes. Hearing him gasp in pain (or pleasure, I can't really tell) makes me giddy! I like watching his balls flatten out on the cockboard while I smash them with my heels. What a challenge I gave him! I order him to come all over my toes after I smashed his cock and balls flat. He managed to have a happy ending...sort of! LOL His balls will be bruised blue tomorrow!
