Cruel Edging Tuck-In with Step-Mom

Now, now, young man, pants off! You know it's time for your edging training! We need to build your stamina if you ever hope to please a partner. That dribbly little thing of yours certainly wouldn't be good for much of anything right now. You remember your training: strip and start tugging that cock nice and slow. We want you fully erect before you begin really humping into that hand of yours. I want you to do exactly what step-mommy says. You're going to edge yourself until you can barely stand it, and stop at my command. As usual, I'll be binding you into bed with a red, hard, denied dick, so that you develop in your edging training as step-mommy intends. I don't want you making any unseemly noises tonight like you did last night, so this pretty gag is going in your mouth too. Sweet dreams, little man...
