I meet up with my girlfriend after her workout. She hasn't cooled down yet, and I see her flushed, sweaty skin. Her hair, carrying the scent of shampoo as it sways in the wind, stimulates my male desire and makes my reason fail. I vigorously thrust my stamina-filled male rod into her vagina, exhausted from training. Then she climaxes so intensely she almost loses consciousness, and that look is cute. Since this sex burns more calories, she's happy too.
