In the heart of a bustling city gym, an ethereal figure stood out among the grunts and clatter of weights. A petite, ginger woman with a tiny, flat-chested frame, her wet hair stuck to her forehead in sweaty strands. Her light purple leotard hugged her athletic body, revealing no more than a nudge of her breasts beneath its fabric. The yoga instructor's pixie cut shimmered under the fluorescent lights as she gracefully moved into an anal squatting pose, her face twisted in concentration. Sweat trickled down her skin, merging with the beads on her forehead, a testament to her determination.
