She laces up her sneakers, her heart pounding with anticipation. Today's route is longer, more challenging, but she's ready. As she starts, she feels the familiar ache between her legs, a hunger that only a vigorous fuck can satisfy. She runs faster, her breath coming in short gasps, her pussy throbbing in sync with her pounding heartbeat. She passes a secluded alley, an idea forming in her mind. She slips inside, her hands already tugging at her clothes. She leans against the wall, spreading her legs, inviting. A passerby takes the hint, his cock out in an instant, slamming into her wet, waiting cunt. She moans, her orgasm building as they fuck, her body tensing, ready to explode.
