A curious teen, left alone in the house, sees this as the perfect opportunity to explore his body and desires. He locks the door, his heart pounding with anticipation. He starts slow, running his hands over his chest and down to his cock, which is already semi-hard. He strokes it through his boxers, feeling the heat and the growing length. He pushes his boxers down, his cock springing free, and he takes it in his hand, marveling at the size and the feel. He begins to stroke, his movements becoming more confident as he imagines a girl's touch, her lips, her pussy. His breath comes in short gasps, his body tensing as he nears the edge, and with a low moan, he comes, his cum landing on his belly and chest.
