Have you been doing it the right way? Just the way Step-Mommy taught you? I need to make sure you're doing it just like the grownup boys do it, just like I told you. Take your pants off for Step-Mommy, and warm up your cock with your hand. That's it... it IS longer now, isn't it. Yes, sucking it yourself does make it longer... It's getting much bigger now; Step-Mommy can tell. Now, stretch the way I taught you and put your legs over your head, hold them, and reach your cock to your mouth as far as you can. I want you to touch it to your mouth, just the way I taught you, jerk it and bring it right to your mouth. Are you getting tired? Step-Mommy will help you hold up your legs while I watch. Are you still tired? Let Step-Mommy take over for a little while; I'll suck on it for you... Now, show me what you've learned, show me how much of it you can fit in your mouth now. That's it... need more help from Step-Mommy? When it's time for you to come, we're both going to lick it as you shoot into your mouth...
