When Leo was little, he felt embarrassed even taking off his shirt at home, let alone exposing himself. His habit of exhibitionism began in high school. He always sat in the last row of the classroom, and the boy next to him loved to mess around during class. Whenever the teacher turned to write on the blackboard, he would secretly pull out his penis and play with it, then deliberately turn to show Leo. High school boys get hard quickly once aroused, and the glans would be rubbed until it was flushed and shiny in his palm.
The first time Leo saw it, he froze completely. His face burned red instantly, and his heart pounded as if it would burst from his chest. He pretended to focus on his textbook but couldn’t help stealing glances from the corner of his eye. A few other male classmates would also bump each other’s groins with their knees or elbows under the desks, laughing hysterically. When Leo got touched, he would flinch hard, ears burning, yet he couldn’t bring himself to refuse. Back then, he didn’t have the courage or impulse to take his own dick out; he would only quietly squeeze his legs together, feeling the growing heat in his crotch, his heart filled with shame and restlessness.
