If you enjoyed the themes in 'Plaything for the Young Asian Mistress,' you might find 'The Concubine's Daughter' by Pai Kit Fai intriguing. It delves into power dynamics and cultural nuances with rich historical detail, though it leans more toward drama than erotica. Another title worth checking out is 'The Last Empress' by Anchee Min, which explores manipulation and survival in a royal setting.
For something with a modern twist, 'The Piano Teacher' by Janice Y.K. Lee blends obsession and control in post-colonial Hong Kong. It’s less explicit but equally gripping in its psychological depth. If you’re open to manga, 'Nana to Kaoru' explores similar power play but with a softer, more romantic tone. The way these stories handle tension and desire might scratch the same itch.
