Two young men in what seems to be an old or haunted house. The eldest went to the upper floor and sees a door barred with wooden planks, behind it was a woman who doesn't talk or is mute. They touch hands and she caresses him, this seduces the young man so he removes the wooden planks off the the door to get to her.
The young man lies down on the floor the woman goes down on him. She comes back up to kiss him during the sex then suddenly bites of his face or lips and it gets bloody. She continues to lap on his blood while the young man groans/screams. His buddy on the first floor hears him groaning and gets scared.
