You're not allowed to jerk to my tits, pussy or ass today. Today you are only allowed to cum on my feet. I don't want you jerking off to anything else. Take your dick out when I tell you to take it out, jerk when I tell you to jerk. Jerk faster when I tell you to jerk faster... and cum when I tell you to cum with a 20 second countdown. Cum on my feet while I suck a big dick!
