The door creaks open, revealing a frantic mother. 'What are you doing?' she screams, as the young couple freezes, their bodies entwined, sheets askew. The boyfriend, quick-witted, grabs a nearby textbook, covering his lap as the girlfriend hurriedly pulls on her shirt. 'Just studying, Mom,' he lies, his heart pounding. The mother, unconvinced, storms off, leaving the couple to catch their breath and laugh nervously, their secret safe for now.
