The suprise and pleasure knocks her out

Luna woke up in the late evening feeling the massive dildo inside her still. It didn't take long to realise her spells had ended, except for the dildo being only marginally smaller than before, as she could feel the base rubbing the inside of her ass and the tip was only protruding slightly from her mouth.

Turned on Luna used a transfiguration spell and extended the base of the dildo into a pair of panties, the tip into a mask, and adding more texture to the dildo so that she'd get pleasure from simply moving.

Having completed her little feat of magic, Luna got up and quickly found a light dress to wear, not bothering with other clothes, and quickly made her way outside, and after a quick apparation, appeared in a London alleyway.

Horny about what she was going to do Luna rubbed at her clit for a moment before moving on.
