Kayla and Kelly had been searching for someone to fuck for close to twenty minutes, and while there were most certainly plenty of people willing to have sex with the fused duo, they were looking for a partner with specific attributes. Since Kelly had become a living cock-tail, she wanted to find someone that she could properly penetrate. Unfortunately, Kelly was massive by cock standards and even amongst the various mutants currently staying in the hotel they had yet found someone with a large enough hole to take her close to two foot thick body. Even when they went to the wing of the hotel designed for giant mutants, they saw no one who looked large enough.
As they continued their search, Kelly noticed a door left slightly ajar as Kayla walked them down the hall. She extended her snake-body over and peaked through the crack. Upon seeing what was inside she immediately wrapped herself around in front of Kayla to stop her.
“What is it Kelly?” questioned the horse-legged demoness
“I think I just found someone big enough to take me” answered Kelly, pointing towards the open door.
Her curiosity peaked, Kayla looked through the door to see what her tail-cock was talking about. Inside was a woman with the body of an orange and white furred fox in place of her legs. Her lower body had six legs however, with an extra pair of fore legs placed between her front and back pair, making her tauric body twice as long as it would be “normally”. She was laying on the floor with her six legs underneath her staring at something out of sight, presumably the rooms TV, on the opposite wall. She had nine voluminous fox tails swishing about behind her, and underneath them sat a plump pussy, clearly soaked with pent up lust. The most important thing about this woman however, was she was huge. Even kneeling she was more than twice Kayla's height, making her at least eighteen feet tall standing, possibly even more. There was no doubt in either of the fused women's minds: this mutant would be able to fit Kelly inside her.
Their minds made up, Kayla knocked on the door as she pushed it open, alerting the rooms occupant to their presence.
“Hello there, my name is Kayla and the woman attached to my butt is Kelly, we happened to catch a glimpse of you through your half-open door and were taken by your beauty.” greeted Kayla
“Eh?” yelped the fox-taur, turning off the TV before the intruders could see what she was watching, “O-oh uh, I'm Gwen, nice to meet you two.”
“We actually noticed that you look a little pent up, so we were wondering if you wanted to 'blow off some steam' with us?” asked Kelly.
“Yeah, I-I'm really horny right now, but as you can see, I'm to large for even your monster cock to feel good for either of us.” replied Gwen, indicating the three-foot horse cock standing erect between Kayla's legs.
“Don't worry, I might not look like it, but I'm actually a cock myself, and we've been looking for someone big enough to take me.”
“W-what, Y-your a c-cock?!” stammered Gwen, before her eyes suddenly took on a desperate look, “Alright, please shove yourself inside me, ever since I got so big there's been nothing I could do to satisfy myself and it's all just been building up all day!”
Without hesitation, Kayla jogged over to Gwen's backside with her horse legs and turned herself around so Kelly would have full access to the giantess's drooling entrance. Kelly, already feeling her mouth fill with pre, lunged into the woman's pussy and began wriggling her way as deep as possible. Gwen let out a cry as her insides clenched down on Kelly's body, slowing the cock-woman's progress as she made her way towards the fox-taur's womb.
As Kelly went deeper and deeper inside, Kayla found herself being forced closer and closer to Gwen's plush rear. Once the demoness was close enough, Gwen began to rub her nine fox tails sensually against Kayla's body, taking care to give her horse-cock and nipples extra attention.
After several minutes of effort, Kelly had reached her limit, Kayla's rear was now pressed directly against Gwen's outer lips. While disappointed that she couldn't make it all the way inside the double-taur, Kelly elected to make the most of her current position by rubbing Gwen's insides with her entire body, sending strange and erotic sensations through her lovers body. The feeling of having something- no, someone inside her was too much for Gwen to take, her insides camping down on Kelly even harder than before. It wasn't much longer before Kayla and Kelly reached their limit, Kelly's breasts heaved as they pumped their load through the cock-woman's mouth, while Kayla shot her cream across the floor of Gwen's room, much of it also hitting the taur's tail and soaking into their fur. The three woman all collapsed, Gwen laying her human half onto her lower back, Kayla dropping onto her butt as her head came to rest against the base of Kelly's body while the cock-woman simply let her body go limp while still inside Gwen's pussy.
