In the hush of a shared apartment, a brother and sister, both amateurs in the art of seduction, find themselves drawn to each other. With no one else home, they can't resist the temptation to explore their hidden desires. The sister, a curious college student, starts by teasing her brother, flashing her panties as she bends over to pick up a book. The brother, initially hesitant, can't help but respond to her advances. They begin to touch, tentatively at first, then with growing urgency. Their amateurish fumblings only add to the intensity of their encounter.
