On the other side of the neighborhood, Lily's long time best friend Fiona had been cooped up inside of her home ever since the merge. Her home was on a horse breeding ranch and they would often play together with the horses. This however had made Fiora a bit of a closet pervert. Even Lily didn't know everything she did. And this was partly why she refused to go out anymore.
Fiona's merge was not bad per se, but what it lacked in tragedy it made up for in obscurity. For the most part, Fiona was the exact same. Nearly completely untouched. That was, as long as she was slightly covered up. Specifically with a hat and a loose skirt/dress.
Fiona was masturbating when she got hit. But unlike any of her normal masturbating, this time she had decided to go all in. She had purchased a custom made alien shaped dildo, with a knotting function built in and that day was her first time ever using it. What made it also special, was that she had managed to sneak some of her own horse's cum durring the time when no one was around that day. Milking him was easy, but cleaning up wasn't, and took time. So she had just finished only a few minutes before the merge.
She had used her fresh horse cum in her new dildo and had planned on having it simulate cuming inside of her. But when the merge hit, her horse cum filled dildo had actually merged to her body, right above her pussy. Additionally, she found out that horses have massive assholes, as her new donut shaped opening displayed itself through her tight yoga pants. Her tail didn't hide it much either. The only other feature that changed was that her ears now were horse ears and stuck out from the top of her head. Interestingly, her dildo had become a real living cock, while still maintaining both its shape and function. Her 2 new large balls were seemingly always full of rich horse cum too.
When she finally showed her family, like she expected, they were a bit hard on her for milking one of the horses, even if it was her own, and wasting the expensive sperm on her own pussy. But they didn't ridicule her that much because that was now a trivial issue compared to other things. Her parents merge was relatively common. 2 halves shared 1 body. Their body was her mother's feminine shape, but with her fathers muscular strength. It had 2 heads, 2 breasts, 4 arms, legs and a pussy with a scrotum hanging below it. Her fathers cock though was now their clit, and would expand outward to full size whenever they would get aroused. The interesting part was that her Mom's voice came from her Dad's mouth and vice versa. Her Mom's head was now her Dad, but sounded like her Mom when it spoke. Same bu opposite for her Dad. They both equally could control their body too with neither having priority over the other. It was a good thing her parents loved each other immensely because now they looked like the other. Apparently their sexual preferences swapped too, so they were even attracted to their old faces.
Fiona's merge was extremely rare given the fact that an inanimate object was involved. Apparently only a few cases were reported, and all of them involved women and a sex toy coated in various organic bodily fluids.
Fiona was going to have to deal with her new foot and a half long alien cock that had many tentacles circling around it, ready to hold down whatever they could find to fuck on their cock. And her baseball sized balls which always would be full of fresh horse jizz.
It had been 3 weeks now, and Fiona was once again masturbating. Her new cock had upped her libido 10 fold. She spent a generous portion of her days now simply masturbating. Because of her inability to control her tentacles, and to prevent her from unwilling raping someone, she had to stay home from school and only under certain conditions was she allowed to go out in public.
Lily and Jackie were still having fun fucking themselves with the dildo when Lily's cellphone rang. Fiona was finally calling her for the first time in 3 weeks. Hurriedly, Jackie carried them over to their desk so Lily could answer it. Lately, Jackie and Lily's movements have began to synchronize. The longer the time they were merged together, the more intuitive their actions were to support each other. Lily on day1 had to hold her leg still to get a sock on because Jackie had not gotten use to her new form quite yet. Now Jackie could even wright effeciently in cursive.
While Jackie was busy keeping balance why teetering back and forth in their brand new 9" ballet boots, the pair listened to what Fiona was going through. When she got to the part about having an alien cock, Jackie's mouth began to water, or more accurately, Lily's pussy started getting very wet. A few drops of semen also started pouring out of their asshole in anticipation.
Quickly swaping out their boots for their favorite pair of 6" platform pumps which they had had custom made with a reinforced heel so Jackie could properly run in them. The pair began the 10 minute jog over to Fiona's house. When they got there, Jackie literally jumped over their 6 foot fence using their new strength instead of having Lily try and fumble with their gate's faulty lock.
They quickly made their way over to the side yard where Fiona's bedroom window had been left open for them to climb through. Once they made it inside, they looked around the room, finding Fiona over in a corner happy to see her best friend again. Jackie was about to move Lily over to hug her when Fiona stopped them.
"Lily wait. You can't come near me anymore. I'm sorry, but this is gonna be how it is. I can't be within 4 feet of another girl or my cock will try and fuck them" said a saddened Fiona. She still was doing her best to smile and not show it though.
"Oh who cares about that, I came over partly to be fucked by you anyways" grinned Lily as Jackie now ran excitedly towards their first official fucking.
"Ah wait no!" Panicked Fiona, not expecting to be rushed as she tried to keep her distance, only to accidentally back herself into the corner. Jackie had stopped and was now just a few inches outside of her strike zone.
"Why not? All of us want it. Even Jackie wants your big juicy cock to mess her up" Lily said, patting her pussy lightly
"But I don't own any condoms, and I can't just go out and get them either..."
"Jackie wants to know if you just cum horse Jizz?" Lily asks for Jackie.
"Jackie? And yes only horse cum. I no longer have any human reproductive capabilities, but I could impregnate a mare if I felt like it." Fiona question as to who Jackie was reminded them that Lily never explained their own situation. So she explained the general gist of it.
"So Jack, is now Jackie, and is your 19 year old, older sister, who has now become your pussy, ass, and legs."
"Exactly!"
"And she is completely fine with getting fucked by me?"
"Here, take a look at this" said Lily. You feel her hand move down and slips it inside of your pussy up to her wrist. As per usual, you collapsed to the ground gracefully, no longer able to focus on balancing yourselves on your heels.
Fiona moves over to help you, which was what Lily was hoping she would do. Not missing that chance, Lily pulled out her hand and grabbed Fiona's wrist pulling her down on top of them. Fiona's cock sprang to life, as Lily pulled off borh of their clothes. Wasting no time Jackie wraps herself around Fiona, securing the 3 of them together.
Fiona begins panting heavily as her cock moves around on its own, searching for the opening it desires. By now all of her tentacles have bound you both together until Fiona fills you up with cum.
The 3 of them stay connected together for the next 6 hours. Fiona's knot refuses to shrink too. Over the 6 hours, Jackie had been in pure bliss as she was being pampered by the tentacles in return for massaging their cock. The tentacles on the other hand, were not mearly panpering their new sheath, but were altering its shape to properly fit their full size. Neither. Group realized it until Jackie began feeling Fiona's balls rub against her labia, with the entire 1.5 feet of sexy alien cock shoved inside of her. Even the buldging knot in her womb had been overlooked. Apparently, you all were now stuck together.
