Thinking really hard about being swept up by the college star athlete, she's well known, everybody wants her, and she just focuses on this pathetic guy in her Biology class. She starts not-so-subtly flirting with him, and by the time he realizes it, she's basically all but claimed him as hers. Anyone who dares to even think about touching him has to go through her.
Then, the night they confess she keeps riding him, overstimulating him, he gasps out. "Aren't y-you tired? You've been.. riding for.. so long-"
She just leans closer and smiles, "Baby, I'm used to training 6 days a week. You're just my cardio."
Anyway- I would totally fuck a jock.
