Begrudgingly Yours

Enya Valencia, dreaded master of the enchanted Hexenkeep of Morgenda, has a new enemy - the celebrated knight of radiance, Helios. The hatred is mutual, but so is their fate of certain death... unless they meet one condition: they must sleep with each other.

"...Shall we start by kissing, hexenkeeper?"

So begins their spiteful romance - at the pinnacle of carnal affection.
