"Swear fealty to me and I'll let you grope my tits as much as you want."

This is what the Demon Lord said to the hero that came to defeat her. The hero weighed his options, but after realizing just how gigantic those tits of hers are, decided to submit. Now he's a servant in the Demon Lord's Army and the Demon Lord's personal masseur. He gets to mess with body, be it her huge tits, her large ass or even her pussy, whenever he wants. And it looks like she's getting warmed up about him too.
