Your eyes land on the dragon that just forced you into being a dragon, probably permanently. His clothes, and yours, still lay on the ground. Your cock is hardening at the thought of getting back at Draco. He may have forced his cock into your ass, but you still thought he was hot and you realized he wouldn't stand a chance with you in your new body, which was now a bit taller than him, and more muscular. You stroke your cock slowly at Draco's abs. He obviously didn't skip a day at the gym. Pulling back the sheets, gently so as to not wake him up, reveals Draco's ass and his cock, hard from morning wood, erect to the full nine inches that had been forced into your mouth earlier. You then also look at your own cock, realizing it was longer as well. You slowly turn him on his white stomach, realizing how heavy of a sleeper he was, and gently pull up his red tail. You thrust a finger into his ass, and this abruptly wakes him up. He involuntarily grunts at the feeling of his asshole expanding. You, not hesitating, slowly slide your cock into his ass.
"Stop it," he says, worriedly, "please don't -" You cut him off: "You forced me into a dragon's body, so now I'm forcing myself into your body, you bitch." His awkward position makes it impossible for him to resist your cock. You held down his shoulders as you began to thrust your huge, thick cock into the dragon's asshole. You hear him grunt in pain every time you thrust into his ass, feeling your cock strike his prostate and send waves of pleasure through his body. The domination you have over Draco turns you on even more. You show him no mercy, despite his pleading, and you loudly moan, feeling your new cock explode with your cum and pure pleasure, and you'd thrust so hard into his asshole that he moaned loudly, his cock cumming despite never being stroked. He gasps in pain or pleasure; you don't care. All you know is you've gotten your revenge as you pull your wet cock out of the asshole you just fucked.
