Adam's boyish legs were suddenly struck with energy and they began to tremble. He walked backwards and found himself falling back onto his bed. His legs continued to shake and with a sudden urge that began in his feet, they suddenly burst out of his white ankle socks revealing feet the size of that had broad souls and tufts of hair on their long toes. Adam extended them in shock but didn't have much time to react as with a gasp, his calves lengthened in seconds only for his calves to form into a diamond shape of strong muscle. His knee's buckled to support what was coming, strengthening the joints into that of a track star. His quaking thighs explode with muscle, creating a platform of masculine strength that many would gaze and sit upon in pleasure. His hips bucked to allow for his teen ass to plump up with muscle, turning it into a bubble butt that lifted him off the bed thanks to his new cheeks.
Adam sat there shaking and sweating in pleasure, his body looked cartoonish being suddenly attached to legs of an athletic hunk but he was so content with the raw feeling of power he felt in his lower body. Blood was rushing through with every breath to muscles of power that would carry him many distances.
