Traffic had been hell, but after nearly forty minutes of driving, Flora, Sofia and their parents had arrived at the hospital and after another ten minutes of waiting, had been brought in for their examinations. Now the family were checked in to their room, which was twice as big as a normal one to accommodate the sisters large, arachnid lower body.
"Well kids, what did the doctors say, anything important we should know about?" asked the sister's father, who was currently idly flipping through channels on the TV.
“Not really for me,” replied Flora, “just to make sure I'm aware of my body's size, to make sure I don't ignore my libido, and that my breasts do have wombs in them so I should be careful if I let anyone fuck them. Sophia's the one who has it bad.”
Sofia rolled her eyes. “Your exaggerating. All the doctor warned me about was to make sure I assert my individuality, since people in situation like mine have been found to lose their sense of self in extreme cases, but that won't be too hard since it turns out I have final say when it comes to our lower body,” as if to demonstrate this Sofia turns their body in a circle before continuing, “Other than that it was just lots of the same stuff they told Flora, since I'm technically partially a cock now I need to be aware of my high libido and to be careful during sex since our cum is apparently extra potent. Honestly I'm more worried about Mom, since at least I have Flora with me if I need a pair of arms”
“Luckily for us,” began their mother's centre head, “We have an amazing partner who will make sure we don't want for anything, right?”
“Of course dear, since I'm still mostly normal theirs not much for me to worry about accessibility-wise. The doctor did warn me that my wings are delicate, and recommended some counselling to help me adjust to my body, but otherwise I'm just as capable as I was before, maybe even more!”
“Of course you will have to get used to having three times the wives, since all three of us are now essentially separate people” reminded the left head.
“Our personalities might be the same now, but the doctor said that over time we're going to start to develop major distinctions between us” added to right head.
“That just means I have three times the beautiful women to love”
As the sister's parents flirted, their mother's cocks had begun to harden, and a noticeable tent had appeared in their father's pants, which was all the signals they needed to know they should leave.
“You two, or four I guess, have fun, me and Flora are gonna go explore a bit.” said Sophia as she and her sister made a hasty exit of the room.
The sisters wandered around the halls for a while, looking for something to do while their parents were almost definitely having sex. After a while of this however, Flora remembered something and pulled out her phone.
“Hey Sophia, would you mind taking over the walking for a bit, I realized I should post an update to my YouTube subscribers since I'm probably not going to be making any videos for a while as we sort everything out.”
Her sister didn't reply, but Flora felt her taking control of their spider legs, freeing her to focus on typing up her message. She left the details vague for the moment, just mentioning that she had been caught in an outbreak and that she had to take some time off. She ended it with a mention of a “special guest” who would be most likely joining her in her future videos however, since her sister would basically have to be a part of her content somehow.
Once the update was posted she watched the various responses come in for a bit before she looked up from her phone, noticing that they were currently in the lobby. As her eyes wandered over the various mutants milling about, she saw a familiar face in the crowd.
“Hey, Gemma!”
“Flora!? What happened to you? And is that Sophia? Why are you fused together?” asked Gemma, returning to her and Margret's room after “visiting” her friends.
“There was a bit of an accident while we were cleaning Margret's room after you left”
“It was my fault,” hastily added Sophia
“Yes it was,” agreed Flora before continuing, “And unfortunately Mom and Dad also got turned into mutants, so it looks like it's just Margret and Isaac that are still normal”
“Actually, Margret and Isaac also got infected as well, in fact...” Gemma awkwardly pulled one of her cocks out of her pants and a blob of cum oozed out before forming into a head.
“Hey you two, it's Isaac, though I've decided to go by Izzy now.” the two girls were taken aback by the talking head that had popped out of Gemma's cock. “I overheard what happened, how are you two holding up?”
“We're doing fine Isaac, I mean Izzy.” stammered Sophia, who was sitting roughly at eye level with her former brother at the moment.
“Are you fused with Gemma like we are?” asked Flora
“Oh, no, I just like hanging out in here, it's surprisingly cozy. But enough about that, we can talk with everyone together. We were just heading back to Margret's room anyways so we can grab her and talk about everything as a family, how does that sound?”
Both sisters agreed to Izzy's idea, so the four woman went to get Margret, Sophia and Flora being just as shocked when they saw her bizarre form, before going to the room the sisters shared with their parents, both Flora and Sophia hoping that they had finished having sex.
