I really can't praise this collection enough. I've been talking it up constantly to friends, and if it looks at all interesting to you, I encourage you to follow that impulse and buy it.
What I like especially is how these stories both deliver the robot fantasy and also dark and ugly and painful sentiment, which is part of a fantasy to experience too. Titmouse is maybe the best erotica writer I know for writing kinks around shame and voyeurism (among many others), and the stories in this collection truly sell the interiority that makes those fun for me.
All three of these are so good to read on your own or with partners, whether you connect more with the robot or the person, but I especially loved Samart's Sweetheart. The sincere engagement with lolita fashion subculture and fantasies of dollish innocence are very well done, and so is the shame and obedience and everything else. I love that this story and its associated art is genuinely about the fun of playing dress-up, among other things.
