In front of the window

You walk up behind Emma as you unzip your pants. She's focused on her dance that she's unaware of your erection standing out above her until you rub it through her hair, making her jump. Guiding her to her feet, you take her hands in yours and press them to the window. Emma looks back with a surprised look as you lift her skirt and rub your cock against her ass. You stroke the underside of your cock against Emma's moist slit as you whisper in her ear, "I want the whole campus to have a chance to see what kind of slut you are." Emma arches her back, giving you easy access as you slide into her snatch. Emma's velvety cunt embraces your cock as you thrust forward. You press the aroused coed against the window, pulling her her bikini top aside so one of her breasts is pinned nude against the glass. Emma watches the students walking below her, hiding her face as she sees a couple guys look up. You watch as a hot brunette catches a glimpse, then stops and bites her finger as she sits and watches. "I think you might have a little girlfriend down there," you laugh. You keep Emma pinned in place as you pound her pussy, lifting her onto her toes as you pummel her. Emma grabs her exposed breast as her hand slips under her skirt. You feel her fingers on the sides of your shaft as she strokes herself. Emma's legs tremble as she rubs her clit and around her stuffed womanhood. Her fingers quickly replace your cock as you pull out and stroke vigorously until you coat her quivering thighs with cum.
