Old fashioned 2

Illustration from a story I wrote about three transgendered girls who get spanked by their girlfriends.

This is Judy; she lives with three other girls, all of whom treat her like a little sister. One night she forgot to do her chores and was given a good spanking in her underwear. Naturally, this was terribly enbarrassing, which is why her cheeks are so red. Judy was spanked by each of her friends in turn, and by the time they'd finished, her bottom was even redder than her face.

PS: If you were going to get a spanking in your underwear, what color panties would you wear?
