Thanks for asking our opinions.
The classic hair slave scenarios I've seen in stories involve a guy attending to a woman or women's hair -- washing, brushing, styling -- in a subservient role. There's some verbal abuse and physical punishment at times. In some cases the slave is *rewarded* afterwards for good behavior. I think I've also seen some dominatrixes who do this, but there's no sex involved.
Another twist is a hair prisoner, which you may recall I like from the stories I wrote for your site several years ago. One or two guys tied down and then tormented by you and Leona with your long, soft hair and other beautiful attributes would be amazingly sexy, IMHO. In too many videos involving soft bondage the guy is untied about halfway through the scene. My recommendation would be to keep your victim restrained through or gas and do some post-orgasm teasing to intensify the pleasure / pain.
