Princess Online #13 features stories and letters from our February, March and April 2000 websites, including pictures of boys in dresses from television and movies, an early 1900s sissy boy pic, boys in summer camp trying on makeup, sisters dominating brothers into girlie clothes, two petticoat punishment posters from Watchdoggie!, two great drawings from Carole Jean, an article about grade school boys in dresses on "Turnabout Day," a class photo of a boy in a girls' school, and a boy in an outlandishly feminine costume for a parade.    There are also great letters about a boy who was brought up by a foster mother who hated little boys, a boy molested and pantied by older kids, an accepting stepmother that turns on a boy and humiliates him in his girlie clothes, a schoolboy who wants to be spanked in pretty panties just like the girl he saw get spanked, a mother who always wanted a daughter, and a highschooler who wants to be prom queen.    It's all here from petticoat punishment to spanking and feminization, from straight to gay. Stories are rated from "G" to "X" and illustrated with 22 photos and 4 drawings.
