Something out of nightmare

You peer back, trying to see who's behind you. The candles are behind them, so they're nothing more than a silhouette against the flickering light. You make muffled whimpering noises into your gag, trying to beg for freedom without avail.

A hand reaches out and touches you, stroking your rump and squeezing it as though considering it's ripeness. You moan into your gag, excited despite yourself at the situation, your nectar starting to flow. The frat boys have outdone themselves to scare you, you think, trying not to let the atavistic fear of your situation overwhelm you, determined to retain your composure.

At that point the figure leans forward, coming more into the light. You have to fight the sudden urge to vomit in terror and it's all you can do to stop pissing yourself.

For as it leaned forward, it's head came into the light. And this was no human head. For no human ever had a face like the one that looms behind you. A great hairless dome of skull and two yellow reptilian eyes, and beneath them no nose or mouth, but only a mass of tentacles quivering where those organs should be.
