Ron's Last Minute Revision

Ron had locked himself in a cubicle in the boys' bathroom on the third floor, it was the only quiet place he could find to practice Charms homework before the test this afternoon. He pulled out his spellbook and turned quickly to the chapter he had marked with a chocolate frog card, the card was of Wendelin the Weird, one of Ron's favourites.
Ron ran his finger down to where it said 'Orchideous', this was the charm he'd been having problems with; every time he tried to produce a bunch of flowers, a bunch of broccoli appeared instead.
Ron steeled himself, raised his wand, took in a deep breath and... was interrupted by the door to the next cubicle banging closed. This was then followed by the sound of a zip being pulled down; Ron sighed and started to pack his things up ready to go in search of a quieter place when he heard the person in the next cubicle's breath start to quicken. Intrigued, Ron pressed his ear to the wooden partition and listened to the noise grow louder, it sounded like the person was in pain. Ron wondered who he was and what he was doing, he shrugged and carried on puting his books back into his bags when he noticed he'd dropped a quill on the floor. He stooped to pick it up and in doing his eye passed a small hole in the partition, it looked like a knot-hole. Curiosity got the better of Ron, and he peeped through the hole.
Sitting in the next cubicle with his eyes closed and head thrown back, was a sixth year Ravenclaw working his hand furiously in his lap. His robe was open and hanging limply at his sides, and his grey trousers were halfway down his thighs along with his blue checked boxers. The robe was the only limp thing in that cubicle.
Ron gasped silently but stayed at the knot hole, staring avidly at the scene beyond. The blonde Ravenclaw began breathing even faster; he leaned back on the toilet and thrust his hips as he bucked up and down, his hand moving up and down the pale length and red bulb. Ron was rubbing himself through his trousers, his own length straining against the cloth of his pants.
Suddenly, the sixth year boy grunted and shot stream after stream of white, which splatted on to the tiled floor. This was too much for Ron, he let out a sob and made a wet patch in his boxer shorts. The Ravenclaw cleaned himself off, using a handkerchief to wipe up and down the softening length; Ron was too busy gawping to realise the boy was making too much of a show of it to look natural. He finished wiping himself and pulled his shorts and trousers up and arranged his robe. He bent down to pick his schoolbag up, ran a finger around the rim of the knot hole and whispered "See you, Weasley." softly through the tiny opening. Ron's eyes widened and his ears went bright red, as the sixth year swept from the toilets.
