Very Careful Extraction

Harry sighed and removed his robes the rest of the way, before walking up to his best friend and kneeling next to her. He inspected her tiny asshole with a scrutinizing gaze, making her squirm under his rapt attention.

"Hermione, you use Scourgify on your... you know, right?" He asked first, deciding whether or not he should cast the spell himself.

"Yeah, yeah, of course... Ever since first year," She whispered, shivering at the cold floor's touch along her back and ass. She wriggled around desperately. "Please, just get it!"

Harry slowly dipped a finger into her soaking wet vagina, moving it around a little as she screamed in pleasure. With a grimace he cast a quick silencing charm on the shack with his free hand, before going back to his attempt to help his friend.

Once his hand was sufficiently lubricated, he pulled it out and slid it into her now-gaping ass, moving around in an attempt to get a grip on the slippery wand handle. It took much more effort than it should have, as his ministrations were apparently enough to cause her to cum, but he finally grabbed a hold of it and pulled the entirely of her 10 and 3-quarter inch wand from her achingly tight rectum.

After he returned the surprisingly clean, though wet, wand to its thankful owner, he gave her a predatory smile and nudged her legs back open, rubbing his cock against her soaked slit.

"Now, I believe you said my reward was 'anything'?"
