Tantaly an Unexpected Christmas Gift a Sissy's Penetration - Mistress Julia

It's Christmas, and I've decided to give my Sissy a gift: a penetration! It's been a year since he last penetrated anyone, remaining in chastity. The first gift, a condom, gives him the illusion he'll be able to penetrate me. But then, I ask him to open his second gift. To his disappointment, it's a doll. His dream half collapses, but he'll have his penetration - with the doll, under my critical eye. I humiliate him for his inability to penetrate me while I call my lover, adding layers of frustration and degradation to this unforgettable Christmas.
