Lots of monster girls apart from the Bicorn have potential for queany undertones if you look at them the right way.

Take the Dullahan for instance - her detachable head means she's a natural voyeur and if her body is absent she's basically powerless. So many variations are possible! 
- If she conceals her head on the top shelf of a bedroom cupboard and then has her body sneak off, she can watch and listen to everything with very little chance of being caught.
- Her husband putting her blushing head on the dresser and angling it towards the bed while her body squirms in bondage elsewhere means she can't look away.
- Turning her head away so the action's just out of view means she still has to listen, since she's got no hands to cover her ears with.
- She can still be kissed or do cleanup.
