The gym's usually a sanctuary for him, but today it's a playground for his insatiable curvy lover. She walks in, heels clicking like a metronome, setting the pace for their impending lovemaking. She's a vision in red, her dress hugging every curve, her cleavage threatening to spill out. She joins him on the leg press, her hands on his thighs, her breath hot on his ear. He feels her gaze on his crotch, his cock stirring. She leans in, whispering, "Let's work out together, in more ways than one."
