So I've been toying with ideas for this, and just want to run a couple of points past the requester or anyone else who has 2 cents to offer.
- How about adding a forced lactation kink? See, I'm imagining that human milk is a great delicacy for house-elves, so serving as "cows" would be part of the slave deal for young witches. (Unless lactation is on SpartanAlchemist's squick list.)
- some f/f, with witches serving female elves as well as males. e.g. I'm seeing Winky sitting on Hermione's face, leaning forward to drink from her breasts as she grinds her pussy into Hermione's mouth. Yes/no?
- I'm on board with the branding, and with the witches having to be available to any/all elves, any time. I'm thinking that a dozen virgin witches are selected each year, at the start of their 6th year, and bound to serve house-elves for 10 years. During that time they can get married if the house-elves permit, but their enslavement continues and the wizard husbands never know their wives are being used by lots of elves. Hermione finds out that Tonks and Fleur are doing this; later on, Hermione and Ginny do it too.
