Princess Online #12 features stories and letters from our January and February 2000 websites, including a cartoon with our kind of twist, a skirt designed for boys, pictures of a boy in a dress from a Dutch television series, pages from a department store catalog showing boys modeling girls' clothing, and eight long illustrated letters that range from the cute and weird to the way out and erotic.    The letters are about a boy spanked for being a sissy, a boy having sissy sex with his mother, a boy being bullied by girls to dress up, a boy being jealous of his sister, a boy stealing panties from the pretty woman living next door, a girl discovering her little boy cousins wear satin panties, a prankster boy forced to wear his sister's prom dress after he sprinkles her with itching powder, and a little boy who wanted to be a cowgirl like his girl cousin.    From sneaking into bedrooms to steal and play with lingerie, humiliating panty training, petticoat punishment, feminization and spanking to a lot of humiliation are featured in this issue. Stories are rated from "G" to "X" and illustrated with 27 photos and 4 drawings.
