Racheal, the school slut

It's Racheal, known for flirting and fucking everyone within a ten mile radius of her sexy little body. She has smallish tits,a C cup, and long black hair. she's wearing a tight t-shirt leaving little to the imagination and matching super short shorts. It acts more as a thong covering the bear minimum. and sometimes less. But what has caught your attention is her movements. she is bent slightly over the desk and panting slightly. Her hand is between her legs, and although you can't see, under her shorts aswell. She's grinding against it furiously and your surprised no one else has noticed. Your manhood has come to life and is stretching your trousers. Racheal suddenly collapses over her desk and bites her copy stifling a loud moan. You subconsciously rub your erection trough your pants. Racheal recovers, sits up and removes her hand from between her legs. Her fingers are glistening and she slowly moves them to her mouth,sucking each independently with a soft slurping sound. She puts up her now clean hand and asks to go toilet. As she leaves you admire her tight behind.
