The boy's body moves with a rhythm all its own, a silent symphony of desire. He arches his back, thrusting his hips forward, fucking his own hand with abandon. His moans fill the room, a testament to his growing pleasure. Pre-cum leaks from his slit, making his strokes smoother, more intense. He can feel it building, the pressure in his balls, the tingling in his spine. With a final, desperate thrust, he spills over, his cum coating his hand and stomach, a visual representation of his BFD fantasy brought to life.
