Your wife is getting ready for her date, but not with you. You'll be staying home, stuck in diapers, just as a baby husband should be. You can watch her get ready, though. Before she leaves, your Step-Mommy-Wife teases you while she tells your babysitter how pathetic you are and shows her how to change your diapers. When your wife comes home she tells you aaaalllll about her date. She knows how worked up it makes you. So, she uses a wand and allows you to cum in your diaper while she teases you. You're so lucky your Step-Mommy-Wife loves you this way.
