Here are a few of my erotica and queer fiction titles you can snag for $0.99 (at time of posting~prices sometimes fluctuate):
Gigglepuss, the title I so love! Lesbian schoolgirl fun, giggling, kissing, toe-sucking... I just love this story. I really do.
Faithful John and the Dungeon Ravens, BDSM Romance, Fairy Tale Bondage Erotica
Ugly Naked People, Lesbian Eating Disorder Romance Short (This one's queer lit fic, not erotica, but it is award-nominated and a category bestseller. And there is nudity.)
Hope you find something you like. For $0.99, it's worth a go!
