"Alright, I will make this simple and easy for you Jen. For your transformation, your body will actively alter its shape to fit my orders and to replace the use of actual equipment. And these bodily alterations will be fully functional, and integratable with other devices and equipment, such as a pump. An example being. If I were to tell you that I want you to have a tail plug in your ass, then your body would close up your asshole and then rapidly grow the tail of my intended look out from it. Or, if I were to say I want to put you inside a bitchsuit with suction cups on your nipples, then your arms and legs would loose everything past their elbows/knees, and end off as flat stubs while your nipples would swell into long, hollow tubes, turn transparent, and have a hole at the end that is sized perfectly to slide in and attach a milk pump's hose to. Get where I am going with this? In addition, these changes will last until I say otherwise, or a situation arises that forcably ends our fun abruptly, such as someone getting hurt. Your body also will adapt to accommodate any changes so that your life will never be at risk. Just incase one of them, for example, removed your ability to breath, and then I forgot to fix it, your body would get to the point just befire suffocating and adapt to either no longer need to breathe, breathe through a different medium, like gills if you are submerged in water, or would even form a new air path, if possible."
"Now for your dare, if I am having you become something specific, such as a ponygirl or say, a cat girl even, then you, while not loosing your ability to speak how you currently do with your moaning, will now also be able to make the appropriate noises to a relistic level. So if for example, I turn you into my horny pet pig, you will now be able to sound exactly like a real pig would. You also will know exactly how to act and what is expected of you in whatever form you are in."
"Lastly, as a failsafe. If at anypoint I say the phrase "Jen full reset" you will undo everything that has happened to you and return to how you are at this exact moment. This undoes all body alterations and speach changes made after this point in time, and sets them to how you are right now. If I say "Jen full reset with mental", then the everything I just said happens, with the addition of whatever mental state you are in, being reset back to this current one too as a default. However, if I specify any mental state you have had between now and when I issue the reset command, you then reset with that mental state."
Jen listened to how Melody used her Transform or Dare and was very excited. Now there was nothing that could stop them from having all kinds of kinky sex. "Jen, I want you to have a nice, big and fluffy tail plug in your ass" said Melody, who also was excited to see the results. Just like what Melody said would happen, Jen felt her asshole close up and a mass swell inside of her where her asshole use to be. Then her spine grew longer, pushing out her back into a long, hairless tail. Finally, hair grew out from all directions, making it extremely fluffy. The hair was the same color as what was on her head, and the tail resembled something close to a large cat's tail, like a snow leopard's tail minus the paterns and coloration as her's was just blonde all over.
Jen looked behind her as her tail started swaying back and fourth from side to side. Unlike how a cat's tail worked with their emotions, Jen's tail seemed to follow more of a dog's tail function, where the happier she is, the faster it wags back and forth behind her.
"Hm. That worked perfectly" comments a satisfied Melody. She was very happy with the results. Now she had more or less full control over Jen's body. "While I am at it, let me give you the matching cat ear headband too."
Jen lost her hearing for a moment as her ears melted back into her head, smoothing out the area they had juat occupied as more hair grew down, filling in the enpty patches left behind. Then on top of her head, a pair of triangular shaped snow leopard ears, covered in blonde fur, pushed out, and her hearing returned, and was even improved significantly. Jen absentmindedly twitched the left one to move the few strands of her hair off of it.
"Yes, I love it! This is going to be so much fun! I want you to Meow like a cute house cat does, Jen." Celebrated Melody.
"Meow meow!" Mewes Jen immediately. To which Melody was even more happy with and went to hug Jen, but as she knelt down to do so, Jen's face was forced down onto the floor as Melody's waist lowered. "Hmm, yeah no this won't do. I want that feature to no longer apply to me, Jen." Said Melody sternly as she was frustrated from being denied a hug by the previous curse. 'Jen belonged to me now, so why is something that her previous owner set in place still allowed to force my pet to defy my desires?' Thought Melody to herself. The curse seemed to take her side on this conflict as she did make Jen completely submissive to her, which is also the last edit made to Jen's behavior in this regard. Jen found that she suddenly could lift up her head again, as long as she kept it below her own waist, which was quite easy to do while she is standing on all fours. "Hmm, almost. Let me rephrase it. If I want her to, Jen can raise her head up to however high I want her to. But unless I say so or desire it, the previous ruling applies." Amended Melody. "Now then, stand up straight so that I can hug you properly, Jen." Jen does as she is commanded to and is then hugged tightly by Melody. "Oh this is going to be such a fun time for me, and you to I suppose."
