I've asked you to stay after school because you are currently failing my Sex Education class. I decide some 1-on-1 tutoring is just what you need to get you back on track. Today's subject is Edging. I am going to give you countdowns randomly throughout our study session and when I get to 1, I want you to edge until I say stop. You will edge for as long as I tell you to, and you better not cum early or else you will fail! Halfway through our lesson, I strip off my clothes, thinking some flesh might makes things more interesting. You are stroking faster now and have edged several times, you are ready to explode! I grab a coin and flip it to decide your fate-heads and I will let you enjoy your orgasm, tails-you must ruin it. After your final countdown, and orgasm the coin chooses for you, there's one more thing you must do before I pass you...eat your own cum. That's right, lick up every single drop if you want an A+
