"You know, I also want to know what it feels to be a taur, but I will give myself a little twist" Ema smiled beginning to type on the computer. "I hope you will be able to handle this!" She clicked to apply the changes.
Ema's body grew two frontal legs to begin her taur transformation, but weren't human legs like Lucy, were black animal ones with hooves, Lucy thought she was turning into a normal centaur, but the legs looked bulkier and stronger to be a horse half, as Ema's lower tauric body finished to develop and be filled with black fur she realized she turned into a centaur, but with the lower body of a strong bull.
Ema checked her new stronger lower body, testing her enhanced strength, the process also made her grow two bull horns above her head, Jeff was still her cock attached to her, but now was the one of a bull.
"What do you think now?" Ema flexed her muscles as her human body also got muscular.
"That looks so hot and amazing, but I fear that thing might break me" both Lucy and Ema laughed. "I have another kinky idea based on yours!" She began to type again until she was done with the changes.
Lucy's shared tauric body got bulkier too, but instead of black it turned white with black spots, their taur lower body had the four breasts Alex had before, so the four boobs merged to turn into a cow udder. For the last change she grew a big cock too, but instead of replacing her big animal vagina it grew below, finishing Lucy's transformation as a complete herm cow taur, the four breasts in her human upper half began to shoot milk, masturbating a little the vagina between her frontal legs that was essentially Alex.
But that wasn't the only change, at least for Lucy, Ema felt a weird tingling in her bull taur genitals, between her anus and cock she grew a pussy too, resulting a herm bull tour.
"Wow, you really have the weirdest but exciting ideas!" Ema waved her cow tail.
Lucy giggled, "so who goes first?"
"I'll give you the honors since I already felt how it was to fuck a pussy having a cock, later you'll give me the pleasure of how is it like as a taur" Ema turned around waving her rear.
"Got it!"
Lucy approached Ema instantly mounting her and using her new bovine cock, experience something that none could felt before, Ema at the other side enjoyed having her insides filled, how her female genitals were way deeper than a human one, Jeff could also feel the sensation of being fucked even if he was still a mere cock. Lucy was filled with many sensations that before she realised she wanted to cum, shooting all of her seed inside of Ema, taking some seconds to unmount her.
Ema cleaned the sweat on her forehead. "Wow girl, you lasted less than me" he joked.
"Sorry, I just felt really excited of experiencing all of this at once"
"Yeah, it really feels amazing the first time, who could have tell that having a dick would feel soooo amazing, I might keep you like this a little longer Jeffy" she laughed, Jeff began to twitch a little as a complain. Now bend over, it's my turn!"
"As you wish"
Lucy exposed her large cow vagina and was mounted by Ema in no time, being fucked by an even bigger cock got Lucy excited, getting an instant erection that touched her cow udder producing milk. Ema's bull body gave her a lot of stamina to fuck Lucy even faster and with more intensity.
To increase the pleasure, Lucy decided to also give Alex some fun, introducing her fingers inside her as her other pussy was being filled, at the same time, Ema grabbed Lucy's sensitive tits expelling milk all over the floor.
Besides the milky mess on the floor Lucy was about to expell something else, as Ema's cock Jeff came, feeling like vomiting tons of a white dense liquid, Lucy also came not only from her pussy but also her penis, shooting a stream of semen on the floor.
Ema unmounted the cow girl, making Lucy fall on the floor trying to rest a little.
"Hahaha, are you okay there? You're touching all that milk and cum mess" Ema pointed.
"Y-yeah..." Lucy blushed. "I just need to recover a little, that felt... INCREDIBLE, and Alex's pleasure made it better"
"Agree! Jeff also made me feel like it was from another world, he's doing a good job as a cock"
"Alex too as a pussy! So, how long will we keep them like this, or should we have more fun by ourselves~" Lucy said in a sensual tone, standing up again.
"Hmmmm... I don't know, having him like this feels really amazing but I also want him to experience more fun stuff"
"So what if we try this instead..." Lucy told Ema her new idea.
