From above and behind, the view was captivating. A half-Mexican, half-British, 18-year-old girl, slender yet athletic, bending over a gym bench in black running shorts that hugged her narrow hips and tiny, firm butt. Her long straight black hair cascaded down her back, framing a small curvy butt. She was halfway through a squat, eyes locked on the observer, a bead of sweat trickling down her forehead. As she turned to glance over her shoulder, a smear of white appeared on her dark blue t-shirt - a testament to her recent efforts.
