What had been an unusual morning had quickly devolved into bedlam for Draco. He had spent the night before with Harry, enjoying the side effects of the Brimstone Potion as he obediently straddled and rode his bed-strapped boyfriend. Harry can get quite demanding when he's thinking with his cock. After waking up and kissing his sleeping boyfriend, he felt mildly concerned at the fast-moving fog he saw outside the window. When his Dark Mark exploded with pain, he knew it wasn't just fog outside. He freaked out when he couldn't cast any protective wards, but had the crazy idea to use his left hand instead. When the spell worked, Draco's worst fears were confirmed.
