Arizona’s day had been weird, to say the least. Just a few short hours ago she had been a teenager on a road trip to a rented beach house with his parents and two siblings. Everything went crazy however after he began using a strange app on his phone that let him transform himself and the people around him. At first he had used it to change his (at the time) older brother’s name to something stupid but eventually led to him turning his parents into sexy female hermaphrodites and his siblings into college-age triplets.
By that point Arizona was slowly becoming addicted to using the app, and continued to use it as they stopped at a diner for lunch. Soon, thanks to locking her and her sisters into being identical, all three triplets were stacked bimbos with horsecocks and a mixture of animal features fucking up a storm in what was now a strip club. Arizona had refrained from joining in on her sisters and parent’s antics until she saw one of the newly transformed bimbo staff and lost control, ravaging her while using the app to turn her into a sexy Octo-mermaid DJ.
After that she fled back to the car–now a kitted out, multi-room RV–to try to get a handle on the situation. First she unlocked herself from her other sisters and gave herself some more conservative dress compared to the string bikini she had been wearing before. After that however her cock once again took over and began making changes, eventually leading to her current form of a busty, six-armed lamia with snake hair and two monster horsecocks.
Now those cocks were plunged into Candi’s fox ears, Arizona’s sister swiftly reduced to a twitching mess as her skull was filled with cock. Arizona had her lowest pair of hands tightly holding Candi’s horns as she thrust, only able to get about half of her cocks’ length into either ear, while her middle pair kneaded her breasts through her T-shirt and her upper two continued to use the app.
“Yes! Ari! Keep fucking my slutty ears!” All four of Candi’s tongues were hanging from her mouth as she moaned for more. Arizona did her best to ignore them as she generated another sentence.
“Candi is having her ears fucked by her sisters twin cocks.”
Her lower heads compelled her to change “fucked” to “bred” leading to a change that the lamia couldn’t see due to her skirt being draped over Candi’s head but she could certainly feel it. Her sister’s ear canals had been hybridized into also being pussies, presumably with all the baby making equipment somehow stuffed into her skull. Alongside this change (which had also been copied over to Bunny due to them being locked in as perfect twins) came muscles that allowed her ear-holes to milk cocks for everything they were worth. This extra stimulation was all it took to push Arizona over the edge, depositing her stores of semen (which were in her breasts rather than the thighs she lacked) into her sister's new wombs.
“OMG Ari! How many times have I told you not to cum inside my ears! You know how fertile my head-wombs are!” Candi attempted to pull away from Arizona’s grip, but the much stronger lamia held on as she used the app to resolve this situation.
“Candi is annoyed at the prospect of being impregnated by her sister.” became “Candi is overjoyed at the prospect of being impregnated by her sister.”
“I can’t believe you might have just knocked me up! This is so hot! It’s such a shame you won’t let me return the favour and put a baby in you, but the next best thing would be to complete the set!” Ari bends over and presents her drooling pussy to her sister, her own cock still at full mast. Meanwhile Arizona was contemplating what she should do with the app next while she banged Candi.
