Go to the sauce

You ask Hermione where she got the spell.

She tells you she copied it down from a book.

You grab the invisable cloth and put it over both you and her.

You find yourself pressing against Hermione so you would be able to both stay under the cloth.

Hermione is now bigger than you so you find your face very close to her breasts.

Each time she takes a deep breath you can see her niples.

She also smells funny. You notice her scent is making your cock hard.

You put your arm around her and placed one hand on her boob.

She did not stop you or even seem to notice.

You walk to the library and all the time you have your hand on her boob.

Suddenly Mrs Norris the cat jumped out of the shadows. You jump a little and pull on Hermione's top making one tit pop out.

Hermione on the other hand froze. She did not move a muscle as the cat looked around. Trying to find what had disturbed her.
