Step-Mommy knows best! I accidentally catch you masturbating in your room before bed and notice you don't quite seem to know what you're doing. step-Mommy can help with that! Let me come in and teach you how to jerk your cock. I'll show you exactly how to touch yourself and stroke it for step-Mommy like a good boy. Slow strokes and going faster and faster until you're ready to cum. You know step-Mommy is always here for advice when you need it ;)
