Something comes up instead

Before you head to class, Ginny mentions to you that she's still missing her wand and has none of her school supplies. You frown and wrack your brain for a quick solution, perhaps call the Hogwarts house-elves and see what they can whip up. But then, you suddenly remembered that you stole Malfoy's house-elf.

Your eyes widen as you realized that you forgot about Malfoy, you glance around before asking your girls if they had seen Malfoy today at the breakfast table. They all shook their heads and you laugh, Malfoy's still tied to the chair naked. You tell Ginny to follow you as you let the rest of the girls go to class.

You go back to the Slytherin dorms and opened the one Malfoy was it. There he was, still naked and tied up in the chair you conjured. As you open the door, Draco sees you and starts thrashing and yelling silently.

"What's the matter Draco? Cat got your tongue?" You taunt him with a sneer.

He grits his teeth, red-faced and glares at you.

"Well, Draco, if you're not going to talk, I suppose I'll be on my way then, but first," You take a look around before spotting his trunk, "I'll be taking some things. Jonty!"

With a small pop, Jonty appears "Yes Master Harry?"

You point at Draco's trunk "Please, move that trunk to my dorm and put all the basic school supplies into a bag for Ginny."

The house-elf nods and pops away along with the aforementioned trunk before coming back with a bag for Ginny. You give the room one last scan and spot Draco's wand, you quickly snatch that up and stuff it in your robes.

With that, you decide to leave, taking Ginny with you. As you close the door, you call for one of Hogwart's house-elves.

"Daris is here, does the Inquizy squad need something?"

"Ah yes, I need you to feed Draco today sometime in the afternoon and clean up any messes he's made"

"Yes, young master sir, Daris will do that" the house-elf nods before popping away. You lead Ginny down to the front of the castle, outside of the wards with your arm around her shoulder. You tell Ginny to hold close as you both appear in Diagon Alley with a small pop. You lead her to Olivander's to get her a new wand, explaining to Olivander that her previous wand was snapped.

After several minutes of trial and error, Ginny got a new wand and you have a devious idea. You quickly pull out the rulebook and jot down a new rule.

Old Rule: It's normal for witches to store their wands in their vagina.

Ginny thanks Olivander for the wand before shoving the 11' spiraling Yew wand in her pussy with a small moan. You pay for her wand before apparating with her back to school while groping her ass. Giving her ass a quick slap, you send her off with a note from the inquisitorial squad that excused her for missing class. After that, you decide to head to class yourself.
