It's dormant and needs to be charged.

After examining it she realized the issue. In order to use it the relic had to be powered. In short it had to take magic created by the act of sex.

"Good news is it isn't dangerous right now and I know how to use it." Hermione stood with it.

"And the bad?"

"That depends on you definition of bad." She laughed. "It needs to be powered before I can unlock it. And the only way to do that is for it to 'feed' off two or more people engaged in sex."

So if we want to use it we have to fuck. Again." Harrys cock twitched at the idea.

"If." She said. "We don't have to but it could help us in the long term. "

"So...do you want to?" He asked. No matter how many times they fucked he would never get enough of her.

She thought for a minute. Carefully she fashioned a cord to tie it in a makeshift necklace. If they did fuck then it would need to be close.

She picked up her spear looking back at her boyfriend and considered her options.
