"Gin, I'm pretty sure that wasn't an ancient vibrator specially made for the Goblin King to raise morale during the 41st Rebellion."
"Oh yeah, Potter?" Ginny raised an eyebrow in a look that Harry knew she intended to be challenging but really just made her look even cuter. Not that he was stupid enough to risk telling her that. "Why exactly might that be?"
"Well," he raised one hand, counting off on his fingers as he went, "First of all, the Goblins haven't had a king since Bragnot the Useless was deposed in the 14th century. Second, the most recent Goblin Rebellion was the 23rd one in 1929, and that barely lasted long enough for anyone to have an opportunity to use a vibrator, let alone have one specially made. Finally, and perhaps most compellingly, it's covered with huge spikes."
"Maybe he was just really kinky?" She parried with a smirk.
"I'll show you kinky, Potter" He growled, grabbing her close from behind and sweeping them both off towards the nearest apparition point.
