James jogged down the steps towards the store room, his hand rummaging in his trouser pocket for the keys, when he noticed light coming from the doorway up ahead, and the sound of physical exertion. Curious, he ambled on towards the room, expecting to find someone that might need assistance, but as he got closer he noticed that it sounded female, and didn't sound like someone trying to move something heavy - more like distress or pain.. or... excitement? Sexual excitement? He was smiled wryly as it sounded like someone was fucking in the store room.
He gently leaned in to peer through the crack in the door, changing his angle until he saw, perfectly framed, a startlingly exquisite erotic sight. A jaw-droppingly sexy young girl, that he recognised from around the building, was sitting spread-eagled on the floor, leaning back on one hand, her pleated skirt bunched up around her waist, her panties dangling uselessly round one ankle, with two fingers of her free hand frantically working in and out of her exposed vagina. James was stunned.
"My god," he thought to himself, "I must be dreaming." He watched for a few more seconds, just to convince himself. "This girl is fucking beautiful. If she is this horny I must introduce myself later." For the time being he wanted to enjoy the rest of her uninhibited display; he felt for his stiffening cock, and started to masturbate along with her.
He watched her thrusting her soaking wet fingers into her tight young pussy, pummeling as hard as she could as her hips bucked hard against them, grunting and groaning - her face was red and sweating and her whole body trembling and her white teeth clenched as she tensed her stomach muscles trying to push her fingers harder against her g-spot and deeper into her vagina.
Abruptly she stopped. She snarled, curling her full red lips and flashing her beautiful white teeth and slapped her hand in frustration at her messy, slickened inner thighs, then gave a guttural grunt as she drew back her labia with the other hand, leaned her head back and just once viciously spanked her engorged, exposed clitoris, giving a girlish yelp as she reflexively expelled the breath she had been unconsciously holding during her fruitless efforts to climax.
She slumped back and dropped her aching arms limply to the ground, with her legs still drawn up and splayed apart displaying her hot wet vagina. Eyes closed, she gasped for breath, her erect nipples defined and heaving against her sweat soaked blouse, and her fine brunette hair wet with curls stuck to her soft face.
