You find out

You tiptoe closer, not wanting to disturb the copulating couple, but wanting to see which slutty student is involved, and with who. Peering through the leaves you see a girl astride a man, writhing and bucking atop him, her dark hair flailing as she moans in ecstasy.

You don't recognise her, and what few clothes she wears are running gear and don't identify her as a student. What you can see of her partner doesn't help you identify him either, and you stay silent, continuing to watch as they fuck.

"Fuck! Oh Fuck So Close! Again! Fuck Yes! Again! Again! Oh Fuck! Fuck! Fuck! Yes!" she howls as she shudders, throwing her head back as she rides him frantically.

"Yeah! Yeah! Yeah! Fuck Yeah!" the man growl as he grabs her ass and drives himself upwards as the two of them writhe and buck towards a mutual climax. Finally finished, she slumps down on him, giggling softly as she nuzzles his neck.

"Oh fuck that was good! I love your cock," she purrs as she wriggles atop him.

"Sure was," he replies. "It's cold down here babe. Let me up."

"Mmmm, of course babe." She rolls off him and stands, mopping her pussy with one hand, then bending to pick up a pair of running shorts. "That was so good," she giggles as she pulls her shorts on, then tugs down her spandex sports bra.

As he stands up you see the man more clearly. He's in his early twenties, lean but well built, and he straightens some running gear as he grins at the girl. "Same time tomorrow?"

"Mmmmm, you know it babe," she chuckles, kissing him. "I can't go long without your cock. I start getting withdrawal symptoms if you don't fuck me regularly."

"Horny bitch," he laughs.

"I'm your horny bitch," she replies, kissing him again. "Your horny rich bitch."

"And you like slumming don't you? Love having some blue collar cock up your snatch."

"You know it. As much as you love fucking a rich bitch."

He laughs and hugs her, kissing her hungrily, before slapping her on the ass. "Tomorrow, sweetheart. Come horny."

"Always babe," she laughs as she turns away, heading back up the path towards the school, and incidentally, towards you.
