Vincent Crabbe knows it's not all bad being huge and thuggish and thought to be duller than a sack of rocks.
His size affords him the position as sidekick to Draco Malfoy, and his slowness gives him the bliss of having absolutely nothing expected of him in class. If he ever spoke up with a correct answer in Transfiguration, he'd probably give old McGonagall a heart attack. So, with no pressure on him academically, Vin is free to daydream.
It's another Double Potions lesson -- with the dreaded Gryffindors -- and Vin notes that Malfoy is in his usual form. Vin hides a smirk as Draco predictably alternates sneers at Harry Potter with cheeky grins at Professor Snape. Vin thinks -- rather wistfully, actually -- that if Malfoy stopped obsessing over Potter he might recognize that he actually had friends -- cronies, at least -- who weren't half bad. Vin knows that he and Greg Goyle are good guys, and way more interesting than Potter and his goody-goody lot. He doesn't know why Draco can't seem to shake Potter off.
Still, Vin can't shake the intensity of Draco's gaze -- even if it's not directed at him. While Snape drones on about pufferfish eyes, Vin sneaks looks at Draco, and he daydreams.
The Christmas holidays. Vin goes with his family to Malfoy Manor for Yuletide cheer and diabolical scheming. When the scheming time of the evening comes around, Vin is sent off with Draco to explore the dungeons.
The damp dark under the Manor. A corner where the moss has been left to grow on the walls, thick and earthy. Draco, slight as he is, pushing Vin against the mossy wall. It only works because Vin is willing. The blissful sanctuary of the dark, the cool contrast between the damp of the air and the heat of Draco's kisses, the slide of Draco's hands. Draco giving orders with his fingers, his tongue. Vin, always willing to take orders from Draco, likes these best. Draco demands and Vin gives and the dynamic works -- because Draco thinks Vin doesn't know any better.
Vin, on his knees, his bulk a pleasant contrast to Draco's lithe body, doing things Greg showed him at his house over the last holidays. Draco mewling, pleading, coming -- Vin licking his own lips, smiling up at Draco, almost blushing at the look on Draco's face. Draco petting Vin's bristly hair, pulling him up into a kiss, his hands sliding down Vin's back --
"Honestly, Crabbe, are you awake?
Did you just see what Potter tried to do?" Draco's eyes are hot on
his enemy across the Potions classroom. Vin just grunts, his eyes
never leaving Draco's face.
