Maika Monroe delivers a spine-tingling performance in this eerie sex scene from "It Follows." The mysterious force she's evading closes in, its presence palpable as she undresses, her breath visible in the chilly air. Her body, a canvas of fear and desire, responds to the unseen threat. She touches herself, her fingers tracing the curves of her breast, her hips, as if to ward off the impending danger. The room, once familiar, now a stage for her private, frightened arousal.
