Step-Mommy encourages you to try on my panties. Then i tell you its ok to touch yourself in them because it feels so good. step-Mommy wants you to fell really good in them. Then im SHOKED that you ejaculated so fast. step-Mommy lovingly teases you for being premature. Then I explain its ok because you are so excited to be step-mommy's panty boy that you cant help it. I instruct you to do it again and cum in step-mommy's panties for me.
