Abs defined, biceps bulged, shoulders broadened, and every muscle in Grace's body followed suit, growing larger with each slow, deliberate breath.
Her sweatpants, chosen for how large they were, now seemed undersized, and possibly at risk of tearing. Sarah would have felt conflicted about this, were she not too mesmerized by the display before her for such complex thought. She knew only that she dared not look away from Grace, and when the transformation was complete, she did not want to accept it was over.
