Jessica giggled and twirled in place as she felt the program modifying her body. She stretched out her arms, watching excitedly as the hair there darkened and thickened. Her forearms bulked up, as did her hands, becoming chunkier and rougher. She felt the changes ripple up her limbs, biceps growing as her shoulders rounded with firm muscle, broadening even as her entire torso widened. More muscle plumped under her chest, even as her breasts flattened and smoothed away. Her neck thickened, cords of muscle roping to her strong shoulders and arms.
