Dirty Harry Drabble #2

Harry stood trembling under his invisibility cloak; he was in the prefect’s bathroom on the fifth floor watching Cedric Diggory having a soak in the bath. As Cedric floated idly on his back amid the bubbles, Harry leaned eagerly over watching him run a hand up and down his lean body. Harry’s own hand was inside his dressing gown, gently clenching and unclenching. Cedric hoisted himself up out of the bath and lay on his side, his hand moving faster and faster. Harry couldn’t hold it back, and let out a strangled sob as he made his fingers all sticky.
