...se would be a few drops of clear liquid that wasn't even really cum (she'd jerked off one of the first years after the nice kid found a book she'd been looking for because she was curious about this very thing a year ago), but Harry seemed to already be full of surprises. The copious, thick jet of solid white cum was far from what she was expecting, and she didn't have time to react in any real way other than the widening of her eyes as seven ropes of cum painted across her face.
Lavender was so shocked by the amount of cum that she didn't even notice as Harry waddled backwards on his knees and flipped her on her stomach and started sliding his cum covered and slightly limp but rapidly re-hardening cock between her big arse cheeks. She was brought back to reality again as she moaned out loud when Harry's large balls brushed against her clit as he started grinding in earnest, putting his whole body behind burying his cock inbetween her cheeks.
Raising herself onto her hand and knee's, unknowingly entering the doggy style position, Lavender began to shake her big bouncy arse into Harry's pelvis as he sawed his erection back and forth, returning it to it's previous rock hard state between her bum cheeks.
