In the heat of a humid Vietnamese afternoon, two high school boys, their uniforms still on, find themselves alone in a classroom. One, a curious 18-year-old, can't help but notice the other's growing bulge. He approaches, his heart pounding, and gently rubs the other's cock through his pants. The other boy, though surprised, doesn't pull away. Instead, he looks up at the older boy, his eyes filled with a mix of fear and desire, as they begin to explore the boundaries of their sexuality.
