Sexy time

In a classroom setting, a person in a blue shirt supports another person in a light blue shirt who is lying horizontally across two desks, while a third person in a dark shirt lies on the desk supporting the person in blue, all three smiling and laughing. The person in the blue shirt lifts and moves the person in the light blue shirt slightly, causing the person on the desk to shift their head and the person in blue to adjust their grip, before the camera abruptly moves.
