Descripción [POV atacante] (inglés):
Since she's already wearing a chastity belt, it's time to turn her into a nice pet and fill her butthole with a tail plug. A little effort and now a cute tail sticks out of her perfect butt.

Descripción [POV víctima] (inglés):
In addition to the chastity belt, you feel how some plug with a tail presses against your anal muscles forcing you to let it in. After long resistances, you notice how the tail is securely seated in your butt.
