"Smile!"

The door to the shared dormitory bathroom, with its sinks and shower cubicles, swings open.

Cass lurches out into the small lounge area in the corner of the fourth floor hallway, with its time-worn orange sofa and its windows overlooking the Old Quad. Two girls and a boy are sitting at one of the tables, playing some kind of board game.

They glance up as Cass stumbles forward. One of the girls snorts with laughter. The boy makes a half-assed attempt to take off his jacket and hand it over. The other girl nudges him sharply with her elbow, forcing him to stop.

Cass makes a noise like “Yieeek!” and spins around, her strong hips and plump bottom wiggling as she fruitlessly tries to get back into the locked bathroom door. The second girl squeals and claps her hands with delight. The first girl grabs her cell phone, moving faster than a cowboy drawing his gun, and says “Smile!”

Cass makes another unprintable noise. Her wide blue eyes flutter left and right, desperately seeking the nearest route of escape. Her hands dance awkwardly over her voluptuous curves, not up to the task of hiding both her colossal creamy-sloped strawberry-nippled comic-book superheroine breasts and the triangle of butter-golden curls between her strong soft thighs.

The cell phone camera flashes.

Cass yelps in outrage, picks a direction at random and bolts in it. Doors open to see what all the fuss is about as she sprints down the hallway. Delighted eyes follow the captivating shimmy of her ass as she rattles on doorknobs, trying to find a friend who’ll help her

Everyone likes Cass. But nobody’s going to complain when a prankster gets a taste of her own medicine.

“So,” you say, sidling up next to Meg, who’s come out of the bathroom in her towel with a huge grin on her face to watch the fun. “We’ve got the whole day ahead of us. What do you think we should do?”
