As the mystery blend of eyedrops, dirt, crumbs and powder worked its way into Jen's tearducts, there wasn't an immediate reaction. However, just as Jen and Clair were about to despair, they could feel a familiar warmth and arousal build up in their conjoined body. "Please let this work out for the better," they both mentally pleaded.
As the transformation began, Jen and Clair's shared belly began to deflate to its normal, toned shape. Their dicks also slowly shrunk as their faces returned to normal. Moments after they questioned if they were returning to a "normal" form, the transformation took a sudden turn. Clair's head, arms and legs all were quickly absorbed into their body, leaving Jen looking like a regular person with two belly buttons. Her legs then fused together into a wide tube that rapidly began elongating. Recognizing that she was growing a snake tail like a lamia, she watched as it stretched out to be nearly 60 feet long and grew light and dark green scales in a pattern similar to that on a python.
As Jen questioned what happened to Clair, her answer came in short order as Jen's head moved over as a new head grew in to her left, quickly taking on Clair's features. Next, they felt their torso shift as it grew a bit longer, with three new pairs of arms growing beneath their current pair. Additionally, they grew two more pairs of breasts, and all six breasts swelled up to a G cup size as their nipples turned into mouths. Finally, their genitals changed with their pussy splitting into three copies of itself, and two 8-foot long prehensile dicks grew out above them.
When the transformation finished, the girls felt incredibly horny from the effects of the powdered pill. Unable to contain themselves, they turned their heads towards each other and began kissing. Their many hands began fingering their pussies and groping their breasts, often sucking their fingers with their lipples. Their tentacle-like dicks were not idle either, and each found a breast to give them a blow job. It took less than five minutes for all this combined stimulus to bring them to orgasm.
To Jen and Clair's surprise, the orgasm caused them to feel like they were about to transform. A pressure built up in their torso as if it were being pulled two ways. Soon, a crease appeared along the middle of their body as they began splitting away from each other, the separation going all the way 20 feet along their snake body. The two halves reformed what they lost, each torso having it's own Jen and Clair heads. Additionally, each of their dicks split in two as well, leaving them with four penises on each torso, and the clits inside their pussies also split in two.
"Wow," Jen exclaimed, panting while trying to catch her breath.
"Well," Clair replied with two big grins, "it looks like we have a lot more mouths at least, eh?"
"Yeah, maybe we better stick with this form for a while so we don't get into an emergency like that again. Plus, this is perfect for business."
"Hey Jen," Clair asked, "do you think we could go for one more round before we head back with Martha? I don't know why I still feel this horny even after we just came."
"It's not just you," Jen answered, "I feel it too. Maybe the pill was more potent because it was ground into powder? Anyway, let's try to make it quick so we don't make Martha wait too long."
Saying this, Jen pulled their other torso in for a sloppy double-headed kiss. They quickly found that kissing with their lipples was an extremely erotic experience, and having two torsos made getting off even easier than before. Before long, both of Jen and Clair's torsos experienced large orgasms. And just like last time, they felt their bodies subdivide, leaving them as a four-branched hydra-lamia. Their dicks and clits multiplied too, giving each torso eight tentacle-dicks and three clits per pussy.
A couple minutes later, Martha returned. "Did you find the ingredient you lost?"
"Ingredient...?" Clair asked.
"Yeah, the pill ingredient you said you accidentally left behind at the fair?" Martha replied.
After a couple seconds, it clicked for Jen that reality must have shifted, changing the reason why they went out to the fair in the middle of the night. "Yeah, we found it," Jen quipped. "Shall we head back now?"
