(1) Slytherin Gangbang

Draco grinned at his fellow blonde, her rubbing on his lap not only getting his dick hard, but pushing her skirt p and showing she'd not bothered with panties. It was time to make up for all the fucking she'd offered and everyone'd failed to deliver. He waved his wand and sent off a call to his friends for them to come back. In the meantime, Surrey's Second Cumdump Supreme (Petunia spent more time there than Dahlia did) presented herself for her arriving cocks.

Sinking down into a split and flexing her phat arsecheeks completely naked. Draco lost his patience and slammed his cock into that inviting mouth. Since the ward broke with Dumbledore's ****, the only slut he'd been able to fuck was Narcissa, his own mother. He'd foolishly tried to be respectful to his girlfriend Pansy and thought to wait until they'd reached their rooms. But fuck that!

The other Slytherins arrived to the sight of a blonde amazon cumdump getting used. It had taken a little time to go from one end of the train to the other and that had been enough time for Draco to nut all over Dahlia's face and start fucking her from behind. Almost as one, the male students turned to Pansy, Draco's girlfriend, expecting to see an angry, heartbroken girl. Instead...

She was fingering her cunt and groaning. Noticing an audience, Dahlia slid off of Draco's cock and moved into a squat, eager to be the centre of a blowbang. Pansy pushed her clothes off to reveal a hot, slutty body with a whorishly inviting pair of HH-Cup juggs.

"None of you are leaving this train until you've all cum at least once in each of my holes." Pansy declared and was almost immediately getting triple penetrated by Draco, Crabbe, and Goyle.

None of the ardent fuckers remembered to put up silencing wards or locking charms, so the sound of two cum-hungry witches getting pounded reverberated through the whole train, inspiring many sluts to make their move and more than a few wizards to go in search of dong-addicted harlots.
