Remember the time I caught you trying to masturbate in bed while I slept? I believe you tried to keep quiet by rubbing the underside of your dick, just below the head...right?
Why don't you try it again? Start rubbing only the underside of your dick below the head until you are on the edge and ready to cum!
Would you like me to let you cum now, or wait until I give you your special surprise first?
Of course you'd like the surprise! Would you like to find what your surprise is right now?
Keep holding yourself on the edge while I show you!
