“Whats wrong with you? First you regress two friends to babies and reduce another to an inanimate robot, and now us into upside down animals is fun? You are sick.” Daniel exclaimed angrily at Mark.
Mark answered smiling: “You know, while I like to see you in pain or misery I don´t need someone to backtalk to me. Therefore lets change your mouths into the assholes that they should become. But because of all the dirty talk I think your tongue will remain inside that asshole, cleaning said hole out of reflex. At the same time your cock will turn to the other side of your body, right above your ass, which will close. There your cock can grow into your new head, featuring a snout and triangular ears on top, whiskers on your cheeks and emerald colored eyes. Your balls will move inside that new head and turn into a new brain for the cats you become. And your underwear should turn into a leather collar with a name-tag around the new neck, the base of your former cock.”
Horrified again Geoff started shouting: “You are ...” only for his voice to fail him, muting him. His mouth stayed open and his teeth receded inside. He could feel his tongue growing slimmer inside but stayed in the hole, unresponsive to him. The same applied for Daniel.
Both got horny when their cocks absorbed their balls before moving around and started growing. Their underwear slimmed down on the base of the swelling cock, feeling like a leather cock-ring at first. But the more the base swelled the tighter the collar was around it, feeling formfitting but not chocking when the new neck finished growing. A blank coin-shaped metal piece hanging down from it. Meanwhile the cock-head turned into a real head, the tip pushing away into the snout with the opening forming the new mouth. From the ball shaped head then pushed out the new cat-ears while right next to the mouth grew whiskers. The head finished with two emerald colored eyes opening above the snout while inside they could feel their cum hardening inside their former balls, merging them into one solid, but empty brain. But it filled itself with all information that the new cat would need over the next minutes.
Seeing their horrified looks gave Mark some pleasure, but he wanted to finish his new pets. “Lets sum the rest up. I have never seen a cat with eyes on their ass, so they will close for good. The same applies for the ears. Your human head then will sink back into the body, which will reform to the new positions of anything in your body. When that's finished your whole body will shrink to a fitting size for a normal house cat that you will be. Finally all over your body will grew short fur in the color of your former hair except your paws and snout, which will have white fur instead. Your human brain will turn into simple flesh in your ass, but your mind will stay in that place afterwards, keeping the feeling to you that your body does anything wrong to you.”
Like with the brothers they didn´t remember before them each boy let a single tear escape their eyes before they closed, the lid fusing it shut forever. Their ears folded inwards like closing a shell, blocking all sound to them. They could feel the pull back on their human neck, slowly retiring into their changed body. Then it felt like they were pressed into a shape smaller then they were, reducing all proportions of their body to the size of a house cat. The itching feeling while shrinking down came from the growing fur all over their body, black for Daniel while brown for Geoff.
They both felt the cat taking over their body and move around a bit, but to them it felt as if they backpedaled. It left them a bit sick from all the shaking the felt. But only then Geoff noted that while their body had changed Mark had never given them new genitals.
