I met Mao, a gym instructor, by chance on the street under the pretense of a casual interview. I approached her, captivated by her sexy, slightly defined abs, and immediately negotiated a real sexual encounter on the spot. Her bouncing breasts with every movement and her irresistibly seductive charm made this an outrageously erotic interview, exposing the raw, uninhibited side of a modern girl. I invited Mao, who was out jogging, back to my place, eager to admire her toned, athletic body—the result of her work as a fitness trainer. Since I'd been inactive lately, I suggested we enjoy some sexy exercise together. We started with basic sit-ups. To make movement easier, she quickly stripped completely naked. She seemed flustered by the sudden turn of events—her shy reactions were incredibly cute. As I held her feet and lifted myself up, her big tits slapped against my cock each time, sending waves of pleasure through me. It felt so good I could have done a thousand reps—my dick didn't resist at all, only pushed forward harder. Since it was unfair for me to be naked alone, I had Mao strip down completely too, then asked her to demonstrate squats. Every time she lowered her hips, I licked her pussy clean. This naughty workout made my cock rock-hard and fully pumped. To test her vaginal muscles, I shoved my dick inside with a juicy thrust. "Ahh, mm, ahh!" she moaned—her athlete's pussy was incredibly tight, matching my rhythm as we intensified our thrusting. We exchanged saliva in deep tongue kisses, properly rehydrating. Finally, I blasted her with a creampie load—semen as protein supplement. Let's keep exercising regularly and enjoy a healthy, active lifestyle from now on.
