The Wilting Amaranth is a short anime visual novel with adult themes and a fantasy setting. It's the only game that I've played from the developers, Reine Works, but they have a few others on St3@m already.
This yuri story concerns a beautiful young witch living in a tower and her two female guests, one there of her own volition and the other by the witch's hand, and the love triangle that is formed by their actions. There's a free, but entirely optional, adult DLC available from the St3@m store page. I've only played the game with this DLC installed, so can't comment on the 'all-ages' content specifically, but with the DLC the story includes a number of erotic scenes, each with non-censored CG images and rather explicit writing.
