Ignoring the professor's drone, two college students, both amateurs to public displays, begin a slow, sensual dance in the back row. The girl to the left, with long dark hair, starts by running her fingers through it, then tracing the neckline of her top, her nipples hardening. Her companion, a boy with a mischievous grin, watches, then mirrors her actions, his hand slowly moving to his crotch, adjusting his growing bulge. The room fills with the scent of arousal, their bodies tensing with each stolen glance, each subtle touch, as they silently agree to continue their lesson elsewhere.
