Macy Meadows, a young, naive stepsister, finds herself in a confusing, yet tantalizing situation. Diagnosed with short-term memory loss, she's vulnerable and impressionable. Her stepbrother, taking advantage of her condition, begins to manipulate her into sexual situations. Macy, unwittingly, succumbs to his charms, exploring her body and desires with him. They engage in heated make-out sessions, their bodies pressed together, her small hands exploring his muscular frame. He guides her head down to his throbbing erection, and she tentatively takes it into her mouth, her inexperience evident but exciting. As they delve deeper into their taboo affair, Macy's memory lapses create a cycle of rediscovery and escalating passion.
