HERR-020 - Delusional Maid Fantasy: My Little Sister Came to Life

Ai Uehara is a household name now, but this is one of her earlier works. It features her signature squirting, but looking back, the freshness of her early days really fits the 'little sister maid' trope, making it a very pleasant watch. It's actually quite rare to see her in a maid outfit, and it's a unique entry even within the 'little sister' genre, so I'd say it's a pretty valuable piece.
