Gostosa, a fitness enthusiast with an insatiable appetite for both exercise and pleasure, finds herself in an empty gym, the perfect setting for a private workout of a different kind. She stretches, her flexible body revealing tantalizing glimpses of her assets, her skin flushed from the exertion. As she mounts the stationary bike, she feels an unfamiliar weight between her legs, a reminder of her unfulfilled desires. She rides, her hips undulating, her breath coming in short gasps as she imagines the bike seat replaced by a thick, throbbing cock. The gym echoes with her moans, her workout ending in a climax that leaves her breathless and yearning for more.
