When Theo spilled himself inside of Draco, the blond came with a shout which was unintelligible, which was a good thing because Theo was pretty sure that he had shouted, "mine" as he had emptied his balls into Draco’s body. His possessiveness is going to get him into trouble. Draco collapsed to the bed and Theo shifted him over, so he could yank Hermione down the bed by her ankles. The drugs that Theo had taken were working well as he was still hard as a rock despite the cum that was even now dripping out of Draco’s asshole.
