Go with Gordon
From Create Your Own Story
Dudley laughs loudly as Gordon shoots him a longingly look at Dudley. "Come on big D, don't ruin the surprise."
Harry thought the surprise is going to be Gordon divulging he have the longest and fattest member apart Dudley's friend group. Harry's little feminine frame follows Gordon still in earshot of Dudley and Ginny's loud crying moans of pleasure.
Dudley yells out. "Hey green eyes bitch, you probably not going to like what Gordon is setting in motion. But just remember during it, that you really really crave to be loved by me. Think of me, and you might enjoy yourself. Haha, Gordon, you are a sick fuck though. But enjoy your showering time."
Harry still couldn't wrap her little brain around why having sex while showering is a bad thing. Harry felt like she was left out of an inside joke. Which she probably is. Since she has never been privy to their fun and games besides the Bully Harry pastime. She follows Gordon.
"You ready baby." He opens the bathroom door to allow Harry in like a gentleman.
Does she go into the lavatory with Gordon?
