I know it's not always easy to obey step-Mommy; in fact, sometimes it's straight-up frustrating! Step-Mommy doesn't let you jerk and squirt your little dick whenever you want. Step-Mommy takes all your money. Step-Mommy doesn't let you go outside or have relationships with other girls!

You love and trust step-Mommy, don't you?
