Welcome, slave, to your latest training exercise. I'll be guiding you through a masturbation session like no other. Every time you start to feel pleasure, you'll be commanded to slap your own face. Yes, you heard that right - you'll be punishing yourself for getting aroused. But don't worry, it's all part of your training. You'll learn to associate pain with pleasure, and soon you'll be craving that slap to intensify your orgasm. So, get comfortable, grab your cock, and let's get started. Remember, you're not allowed to cum until I give you permission. Now, slap that face and let's begin!
