It drops her into a portal

She dangles, slowly rotating upside down from the suspending tentacles. Below her, more tendrils form a woven circle of flesh which throbs and quivers sensually. Hermione cries out and struggles against her bonds, but she’s unable to tear herself free. The circle beneath her contracts and expands like a simplistic mouth - or something further down south.

The maw pinches shut and holds closed for a moment, bulging and shuddering like it relishes whatever it’s doing, and then it expands again. Where once the smooth stone floor ran slick with mucus, a gaping pit of convulsing flesh stretches impossibly deep.

Hermione blanches at the steamy exhalation which flutters her clothes about her, “Oh fuck, oh fuck! Don’t eat me!” Unceremoniously, the tentacles release her and drop her straight down into the gulping esophagus, where her terrified shriek vanishes like a stifled gasp.
