The lady in the gym

The gym was filled with the hum of weights clanking and the thrum of exertion. Sweat glistened on every face, and Charles was in his zone, focusing on his reps. When an unexpected voice startled him, he looked up to see his neighbor, Sarah, standing a few feet away. "Hey, still pushing those limits, aren't you?" she said with a smirk. Charles wiped the sweat from his brow, wondering if this encounter was about to escalate. "You're looking good, Sarah. Same old routine today?" His tone was casual, but there was a hint of tension in the air. The moments stretched, and Charles braced himself for what was to come next.
