I Thot You Was a Toad's manga / #master x slave(2)

Eiji, the robot cat-boy love machine maid, is too clumsy to be of real service. Fortunately, he's given to a very forgiving master.

Dark oneshot about a BDSM encounter with knife slashing, drugging and rape-play. The final scene makes it clear that consent was implicit. Although this is framed as a one-off, there is more that hasn't yet been translated. This is a good story for people looking for hardcore kink.
