The door is locked from your side, you unlock it and you descend into the darkness, only using your phone as a source of light.

Maybe you don't remember, but the basement external door was open.
When you descend the stairs, you find the plant-like creature lurking close to you, like a silent, deadly stalker.

You don't have time to escape upstairs, the creature is desperate and reacts with unnatural fear inside the house, something is driving the creature mad.
He brutally strips your clothes and engulfs your head with his powerful flower-like maw.

You muffled screams sound inside the head of the creature and he uses his greenish hands to lift you... he's swallowing you whole and trying to get out of the house!

Your head hits his stomach filled with liquid pollen, you start to drown and you swallow part of the pollen... your desperate body reacts with a sudden explosion of lubrication and dilation, your pussy is dripping wet and you immediately feel sedated. You lost control of your sphincters during your last moments of life you think that you are cumming.

This a horrible, humiliating orgasm, your story is ended.

THE END
Swallowed by the Demogorgon ending

Task: Wrap your body in towels or clothes previously moistened with hot water. Use lots of lube on your private parts. Start rubbing your pussy with clothes or towels, pretending that it is the creature that is devouring you and that you have no way to escape. Imagine the creature swallowing you. Insert 100ml of warm lube in your pussy, spread it, and expel the lube when you cum to simulate that you lost control of your lubrication and dilation.
