Yeah.... he did, I was just being a generalist when pointed out Nifty as the last story I read there - Middle-class Slave Revisited (as good as the original) - had a bit about younger boys being enslaved (an alternate US with slavery legal) for 5 years as indentured servants by their parents and, yes, it explored their sexuality to a small degree. Though after the age of 16 except for the one boy who knew he was gay, then at 15 he was topping another 35 year old slave, who eventually fell in love with him, but ultimately lost him when the boy's indenture ran its course -- but I digress.

I don't know of a place to look for little girls, they were never in my sights even as a little boy. Though I guess he could look on the lesbian side of Nifty, but I never have.
