Before you can even take a step out of the store, a man in a dragon costume, or so you thought, approached you. You noted how realistic his costume was compared to yours. His tail was animated and flowing behind him, not just statically hanging from his ass like your tail was. You could see steam coming from his dragon nose as he breathed in the cold air, and you could see his tongue move in his snout as he spoke to you.
"Hey. I like your costume."
"Oh, uhhhhm, thanks."
He was wearing a furry, red, Japanese dragon costume. He was slightly taller than you in costume, and had the body of an athlete. Slightly more athletic than you. He was wearing nothing but shorts, and presumably boxers.
"Are you new here? I can't say I've seen you here before."
"Yeah."
"Oh come, I'll show you around. My name's Draco."
You follow the - honestly kind of cute - dragon into a building. He tells you it's one of the dormitories for zoo employees - goddamn this really was a huge ass zoo. He takes you to one of the dorm rooms, and locks the door behind him. Draco gives you a sly smile and says, "You are in a costume, but to transform you all I need to do is fuck you." You have no time to react as he pushes you against the wall against your will, holding your hands against the wall as he presses his body against yours and forces his snout into your mouth through your costume's snout. He swiftly tears your shirt to shreds, revealing your muscular chest. You try to push him away to no avail. As he forces you to make out with him, he, with his right hand, undoes the zipper on his shorts, letting them fall away, and then his boxers, revealing a slit in his crotch. His cock, hardening, emerged from the slit and that is finally when you realized he was an actual anthro dragon. He rubs your chest and lightly plays with your nipples through the costume, enjoying the feel of the costume's white fur. You take the opportunity to push him away and try to unzip the costume. He reaches behind you and yanks the zipper clean off its tracks. "There. Now you're stuck, and you won't be getting away anytime soon, trust me."
You panic as he pushes you against the wall again, you now sitting on the floor, and forces his now hard cock into your mouth. You moan in pain with every thrust of his huge cock as you are forced to suck it, pleasuring Draco. "Oh yeah, that's so fucking hot..." he tells you, through moans and grunts, as tears begin welling in your eyes from the pain of his cock. He shoots cum into your mouth, forcing you to swallow by keeping his cock inside your mouth. You try to get up and run to the door as soon as he lets up, but as soon as you are fumbling with your claws with the door, and are bent over, he forces your shorts and boxers down, and strokes your cock, making you moan in pleasure, despite you still trying to escape. He holds up your tail and forces his nine inch cock into your ass. You grunt in pain and pleasure at every time he thrusts his cock into your prostate. He brings your human cock out of its slit and strokes your cock to harden it as he forcefully penetrates you. You feel yourself shooting almost a gallon of cum as Draco cums into your ass by force.
You, having blacked out, wake up groggily in Draco's bed, naked, covered in his cum. You jump out and examine yourself. Draco, by forcing you to take his cock, had turned you into a dragon.
You sit up in shock. The fucker raped you into dragonhood. You, Draco still soundly asleep next to you in bed, silently get out of the bed to go check your body out in the mirror. You examine your hunky body in the full body mirror, your cock now sitting in your new slit, flaccid. You reach down with your blue and white clawed hand into the slit, and are able to see your new cock: red, but still somewhat human, yet also more draconic. You run a hand down your chest's white fur, turning you on slightly at the feel of your powerful muscles rippling below your new furry skin. You ran a hand through the hair on your head; now blue with white streaks, sitting in a small mohawk in between your horns. You, remembering you are a dragon, breath out as forcefully as you can, and are in awe at the sight of blue fire exiting your mouth, and even more in awe at the fact that the skin on your hands seems to be completely unaffected. You look around the room, breaking out of the narcissistic mirror trance and get an idea...
