I just wanted to give a little speech here on the importance of my sissies wearing panties (assuming they feel good, fit, and look sexy). Panties are important because they are a daily private reminder of my sissies' status in life. They also feel nice to wear, and make my sissies feel sexy, and are thus reinforcing the sissy lifestyle. It's a positive feedback loop: the more sissy wears panties, the better she feels, and the more she wants to wear panties, as well as find other reinforcing behaviors.
Anyone wanting to enslave a sissy (or even an otherwise male submissive) should immediately replace all the sissies underwear with panties (that feel good, fit, and look sexy) as soon as possible. I mean throw out absolutely every pair of old male underwear.
If she goes to the doctor, she can wear a nondescript black pair, but nonetheless, panties.
