The creaking floorboards and chilling drafts only serve to fuel the siblings' primal desires. Cornered in the cramped, cobwebbed closet, they succumb to their carnal urges. The brother's rough hands explore his sister's body, squeezing her ample breasts and slipping under her skirt to find her soaking wet. She whimpers, pushing her hips against his hand, desperate for more. The dim light from the flashlight casts eerie shadows as they rut like animals, their bodies glistening with sweat and juices, until they collapse, panting and spent, in the haunted house's embrace.
