“All I want is to make you and mom feel good,” Jen said as her twin headed, snakelike father/mother flicked their tongues at her.
“Sssssuch a good girl,” the left head said as their neck grew longer. Green scales coating the lengthening flesh.
“Ssssshe is. Wanting to pleassssse ussssse,” the right head agreed as its neck also elongated.
“And ssssshe smellsssss ssssso good,” a third head added, appearing from between the first two.
“You’re changing so fast,” Jen said, quivering in excitement.
“Well, we can’t help sssssmelling your deliciousssss ssssscent,” the middle head acknowledged.
“You sssssaid it wasssss you who wasssss doing thisssss to usssss,” the right head pointed out.
“Naughty girl,” the left head teased. The three heads, each on necks several feet long, slithered over to Jen. The teenage girl trembled in anticipation. The middle head got face to face with her as the side heads nuzzled into the sides of her neck and each took in a deep whiff.
The changes were very fast, the greater number of heads allowing more pheromones into Alex’s system at once. More and more heads appeared, accelerating the changes as they too crowded around Jen. Each head became less human as their jaws pushed forwards to more resemble a snake like maw, and each of the heads four pupils became slits. Alex’s wings began to molt as leathery flesh replaced the feathers, however they still remained just as colorful. The most dramatic change was her size. Each breath in made her surge in size. Jen could hear Helen groan in discomfort as the added weight of her spouse was dragging her erect cock downward.
“Alex, sweetie, you’re starting to hurt me,” she called out. Having no intention to hurt their wife, Alex uncoiled themselves. Jen grabbed hold of the closest head which was itself larger than her entire body at this point. Two loud thumbs drew Jen’s attention downwards. She saw that two massive arms had grown out of Alex’s snakelike torso. They were muscular and covered in green scales. Each with three massive, clawed fingers. Forget naga, or wyvern. Alex was now a winged hydra.
“Thank you Jen, you’ve been ssssso helpful,” The head Alex was holding onto assured.
“You’ve made usssss big enough to properly make love to our wife,” another of the ten heads explained.
“Big enough? Sweetie you’re bigger than I am now,” Helen chuckled. She had a point. While their torsos were the same size. Alex’s long body dwarfed the centaur, it having to coil around them several times, flattening many of the neighboring houses.
“Well, we needed to be big enough to handle thisssss,” a head informed as Alex reached out with an inhuman arm to grab hold of Helen’s dick. Despite having been dragged underneath her long horse torso, Helen’s cock still stuck out in front her for half her body length. The tip of her horse cock dripping precum.
“You big flatterer, just get over her and fuck me,” Helen demanded and grabbed two of the heads, forcing them into her massive tits. Each breast the size of her human torso. All the sudden movements sent Jen tumbling. She slide down the insanely long neck and body of Alex, the smooth scales giving her a gentle ride despite the height. Eventually, Jen made it back to solid ground. But that was the last thing she wanted. Now her mothers were even further away. How was she going to pleasure them now that they were so big.
“Oh my god. Jen, is that you?” A familiar voice called out. She looked over and saw her maid Martha. She must have rushed over to see what was going on. Such a loyal girl. Her day off and she couldn’t help but come to their aid. A thin girl, 26 years old with dirty blonde hair cut into a nice bob. Her modest bosom in a plain grey tshirt and her meager hips in a pair of blue jeans. This was perfect. She was perfect. All she need was some changes. “Why do I smell lemon pledge?” Martha asked.
“Because of me. And trust me, you’re gonna love it,” Jen smiled as she crawled over to Martha, her 5 pairs of arms making it easy to close the gap between them and grab hold of the maid.
“What are you doing?” Martha cried out.
“Ssh. Just take in the smell,” Jen instructed and kissed the older woman.
Martha couldn’t understand what was going on. But, as the lemony scent filled her nose…
