Bordato fino al culmine con un vestito a rete

I know you love fishnets and I know you love feet, but you're here to amuse me so I'm going to set you a little challenge... You're going to stroke for my feet, and every time you get over excited and think you might be close to cumming, you're going to stop, take a deep breath and come back to your senses. You're not to cum without permission no matter how much I tease you!
