Reddit mentions of At Her Feet

I mainly read lesdom erotica, so take with a grain of salt if you're into F/m stuff

Claiming Katy (free online) is pretty excellent (though rather extreme) sadomasochism with a side-helping of service submission. Sophie (protagonist) doesn't deserve Katy and is a terrible dom, but she has actual character growth and becomes better over the course of the story. Expect edge play and not enough negotiation, but... Fuck, it's hot.

At her feet (not free, but worth it for the ebook) is warm, fluffy and wholesome-ish mommy dom/little girl stuff, at least in that it's extremely clear that the two women are totally into each other and their dynamic. It's not really my kink, but I had a smile on my face for most of the time I was reading it. Would recommend based solely on how happy it is.
