Your body quivered and shook as you felt his massive canine rod deep in you folds. Karth held himself against your body, the base of his shaft, the swelling knot expanding, inflating against the new lips he had given you, stimulating your sex in ways you never thought possible. As you looked down at your hands, you began to notice they were starting to dry and crack. At first it frightened you, but as it progressed you began to notice the cracks were forming in patterns, the drying making the skin smooth and shiny. Reaching with one hand, you touch the back of the other and find they were smooth like scales, but not like any kind of scales you've seen before.
Karth slowly pulls out, then thrusts back in, bringing you back to his cock, a moan escaping your lips while you felt the changes move up your arms. Watching in amazement, you saw your nails grow and curl, taking on the look of claws, just as the growing scales began to change color, taking on a silverish tint that you couldn't quite nail. The scales moved up to your shoulders and neck, and you felt dizzy, like the world was moving, before realizing your neck was getting stretched a little, becoming longer and more flexible, as the spine changed where it was connecting with your skull.
Karth purred as he watched his magic change your body more. "You're going to be something exotic, my dear." He began to pump against your pussy, his balls slapping against your cunt, causing you to gasp and moan as he rocked hard inside you. You look forward at your friend, who was smiling as she watched, a hand on her breast, massaging it as she also fingered herself, wet from the scene, probably thinking back her own transformation into a vixen again. It was hard not to imagine what she went through, considering you were going to something so very similar, if not with a different result.
You continue to watch as your body is rocked back and forth, Karth's... your master's hands on your hips, causing you to move against him, increasing the sensual slaps to your cunt, as his penis began to feel bigger. At first you thought it was just his knot, having swollen enough that it could tie itself to any vixen, but after a while you realized his entire cock was bigger. It was thrusting deeper into you with every pump, touching new and strange parts to your body, stimulating parts of your brain you didn't know were there.
It was enough to make you scream as you climaxed, your head looking up to the sky, mouth open wider than before, a long tongue sliding out from between a set of sharp teeth. You were lost, the focus of your world compressed to your pussy, imagining perfectly the massive canine shaft inside your vagina, the walls constricting around it, pulling and kneading on the sensitive hotdog in between your walls, trying to milk it. But your master was not finished. He kept going as the changes finished on your head, you feeling long hair cascading down the back of your head, over two long pointed ears on either side with a pair of horns sticking out from above, while your face was a broad draconic snout that held two eyes with golden, slitted pupils.
The scales continued down your torso, moving down your back while your chest and stomach were barely touched, the scales barely visible as they were very smooth, changing a color that was close to the scales but a little darker, the nipples becoming black to be very visible against your silvery body. As the scales reached your hips, the legs began to shift and move, causing you to lose footing as the legs started to move up the torso.
Karth had to grunt as he had to move his hands around, your legs no longer connected to your hips as the began to change, thinning a little as your feet shifting, toes stretching out into flexible digits, the big toes moving down as they grew, rotating slightly, all as the nails turned into similar claw-like shapes as the hands. The legs moved a couple inches below the arms, and by then they were no longer legs, but another set of arms, identical to the first.
You used both sets of arms to try and keep yourself up, to give your master support as he kept thrusting, your body quivering from the first climax, wanting another so badly from him as he hadn't satisfied you or himself. Your shoulder blades began to feel pressure, hurting slightly, causing you to look back with your long neck, seeing your handsome and loving master, who smiled as he kept thrusting, fangs showing as he grunted, his penis squirting a little pre inside your vagina, a warmth that didn't go unnoticed.
Watching as his hips pumped against yours, you noticed that some new appendages were growing out from your shoulder blades, stretching and pulling at the scales, first as small lumps, quickly becoming long cylinders that cracked half way, bending as a thick membrane began to grow out, connecting the ends of the appendage, veins visible through it. It didn't take long for you to recognize that you were growing majestic wings out of your back. They were stretched upward at first, before the magic finished growing them, which caused them to fall flat against the ground, the impact hurting you a little bit, making you hiss from the pain. "Ow."
Karth grinned. "Sorry." He said, rubbing your spine to sooth you, all while the spine started to stretch backwards. The spine kept growing, pulling at the body as it stretched downwards, scales covering your entire body, including your vagina. You found yourself getting repositioned, your chest and head forcibly resting on the floor as your ass was up in the air, or whatever it was, as the spine had temporarily made it vanish, pulling out into what looked like the start of a powerful tail. Karth kept thrusting against you, having some trouble now due to the tail ending up over his shoulder, getting longer by the second. "Ugh... Now I'm regretting this." He said under his breath.
It felt wonderful, his massive cock inside you, spinning around, or more accurately your pussy spinning around his cock, feeling it in new angles. Your tongue flicked about as you moaned and hissed from the thrusting, his cock larger still. It felt like with every foot your grew, his cock would expand by an inch, remaining proportional. You felt your new tail grow and land on the floor, continuing for what felt like forever. "M-master.. Please... Let me go. Release me." You scream, wanting him to finish the deed.
He grinned, knowing you were so close to being done, but he had to complete. "Almost there, my dear." He patted the place of her back where the hips fused with the coils. The tail had finished growing, the spine becoming extra strong while everything grew into place, before he let out a howl.
You felt the magic changing you tingle extensively as he howled, and it was an abrupt shock. Every inch of your body was assaulted with untold pleasure, causing your torso to shake as you screamed, climaxing again, this time feeling his hot fox seed invade your waiting uterus, feeling the deed of his magic done, and your body finished.
You lay there, on your breasts, panting with your tongue out, as you felt the gush of his seed warm your nethers. It was hard to tell how long he held you like this, but after what felt like hours, your master began to stroke your backside, soon followed by him pulling out of you gently, your body falling onto the ground in a loud thump. You don't move, remaining where he left you, unable to rationalize what happened. It was so magical, so perfect to you. It was hard to imagine it ending, but you knew it had to. Licking your dry lips, you look up at him. "Master?"
Karth looked down at you, his latest handiwork, with a grin of accomplishment, standing naked before you, his shaft still out of his sheath. Your eyes bulged in amazement from the size of it, almost the size of a horse’s. "Holy m... master." Your heart flutters. Karth grins and laughs. "Looks to me taking your male essence was the best one of all. You had a lot of it in you." He knelt down beside you, bringing a hand to your head and stroking it through your long black hair. "You look beautiful."
He stayed where he knelt for a minute, examining his handiwork, looking it over carefully, grinning at the V at the front of your pelvis, the slit in the middle of it. "Now this is going to be interesting." Standing up, he looked at the vixens. "Help her up and to her room. She's going to need a completely unique wardrobe from the rest of you."
The vixens all nodded, walking up to you as they looked down in awe. You looked at your body, finding it looking so exotic and beautiful, but found you weren't able to move your tail or wings, and the second set of arms were moving at the same time as the first. "Master? How am I to move when I can't move my tail?"
Karth looked at you for a second, before kneeling down, his massive cock a foot from your face. "Yes, that would be a problem. It'll take you months to learn how to move and control this body of yours. I can't make you learn it immediately, but I might be able to give you a headstart." He takes your head in both his hands, and with one hand holding you steady, places another on your forehead. Immediately his hand begins to glow, something you can only see form the corner of your eyes, before you feel something in your mind, like a cloud or fog in it, but also feeling like something was moving your mind around. "M-master?" You ask, only for him to cut you off.
"It's alright. I'm helping you adjust. I won't make you what you don't want. I'm not changing your memories, your desires. I'm just making all those years of you growing up as a human become years of you growing up as this. All the instincts are there with your body, but your mind doesn't know how to connect to it yet. This should give you a headstart." He said, your tail twitching, a sign to him that he found the right instincts, and began to settle them down around your mind so you can more easily find them. "There. That should do it." He let go, moving back and standing. "Now take her to her room. Janice, since you're her friend, I want you to look after her and take care of her while she adjusts."
Your friend bows her head before moving towards you, along with the over vixens, all grabbing you from all over, lifting you up with some difficulty, before moving you to your room. It was a beautiful location, well lit with silk sheets hanging on railing and banisters, a large pile of pillows in a large pit, a place the vixens carefully settled you down in before catching their breath.
"Wow, I didn't think Master would make someone so big." One said. "I know. Still, she is beautiful to look at."
"You would know. You were a lesbian before Master changed you." Another said with a British accent.
"Oh shut up. I should never have told you that." The first one growled.
"What? We all need love, and at least we got to know that you can do us favors."
"Yeah, but Master said that the only one who can give us love is him."
"Both of you, enough. Can you all leave, so I can help her out?" Janice asked, interrupting the discussion.
They both look at her, then nod, leaving with the rest of the vixens.
"Thank Master..." Janice sighed, sitting down on one of the pillows. "What do you think of your new room?" She asked, turning to you.
