Drain her mind

A thicker tentacle worms across the slick stone floor to just beneath Hermione’s head. It raises itself like a snake, ready to strike, and Hermione flinches instinctively. As if to taunt her, it remains poised for several seconds, drifting back and forth along with the sway of her dangling. Then, it lunges. It’s bulbous head flares out into a star of suckered tendrils which slap against her forehead and suction themselves firmly on.

Hermione can already feel something, a buzzing in her mind, and she cries out, “W-what are y-you doi-nghuhgh?!”

The voice pierces her mind, “I’m taking what I want… everything I want. So do hold still, or this could be messy… for you…” Hermione’s eyelids flutter and her eyes roll back as the suckling probe siphons away her mind.
