As Jen and Claire tried to see what was at the top of their body using their limited view, they continued to hear the sounds of classmates transforming mixed with various moans of pleasure. Stimulated by these sounds, they felt their cock-bodies becoming longer and harder while slightly improving their vantage point. They also felt a familiar pressure near the top of their dragon torso, and moments later their suspicions were confirmed when a splash of precum fell on Claire's head. Realizing she could control one of the dragon arms, Jen reached up to feel where their next should be and encountered a massive dick.
"Well, guess that answers that question," Jen remarked.
Due to a combination of where they were sitting and the inability to rotate their heads, the sisters could only see about a third of the classroom, the space in front of them. One of the girls at the front of the classroom changed such that she had a mass of octupus tentacles for hair, and parts of her skin looked similar to the exterior of a starfish. Additionally, she now had four large breasts and six arms with seashells for fingernails.
Next to her, a guy named Mark and a girl named Anya that Claire knew were dating each other started undergoing a change. Both of them started becoming rather pale as if they rarely went out in the sun, and Jen noticed that Mark was rapidly becoming more feminine. Mark's hair began to get longer and darker, soon reaching down to the small of his back, a changed mirrored by Anya. Mark's chest swelled out with ample breasts til they reached the same approximate H-cup size that Anya expanded to, and both of them grew a second pair of arms. Soon, the two of them were drawn closer together until their hips merged halfway, leaving them with four legs and two pussies. However, the change suddenly took a drastic turn as their shared rump began expanding outward behind them while their legs spreaded out and divided. As the bulbous shape took form with a shiny black hue and their legs became skinny and chitinous, it became clear that the couple became a conjoined arachne. To round out the change, both of them grew six more eyes on their foreheads and their arms became coated in chitin from the elbows downward.
Jen and Claire soon had their attention diverted when they heard the starfish-skinned girl shout a sharp "Ah!" Trying to see as best as they could, they saw a classmate with metallic skin apologizing profusely. When they looked at the starfish girl, they were shocked to see one of her arms had broken off. However, shock turned to curiosity as they saw her arm quickly growing back. Furthermore, they noticed the severed arm on the floor was also growing back a new body. Before long, there were two copies of the girl standing side-by-side.
Before they could try seeing what anyone else in the class turned into, Miss Taylor cleared her throat loudly to get everyone's attention. "Now class, I know many of you are fascinated by the unique smell of Jen and Claire's once again failed experiment, but I need you to pay attention. I won't have another repeat of the last class' distraction, am I clear?"
Looking at the teacher, the sisters saw she also was changed. No longer did she have lizard traits, she actually looked a lot more humanoid. However, they saw she now had 8 breasts, each of them looking like they were made of something between silicone and glass, and each housing a different colored liquid. Additionally, she now had four transparent cocks on her groin, with another set of liquid sacs beneath them.
Miss Taylor continued, "Now mix the next two chemicals in the manual as so..." She then pointed two of her nipples at the beaker in front of her, then squeezed them to shoot the liquids into it and caused a chemical reaction.
The rest of the class went on in a similar fashion. The sisters had a hard time doing the experiments with their clumsy dragon claws and poor field of view, but Miss Taylor seemed understanding of the problem. With class over, Jen and Claire saw they had time to kill before cheer practice because there wasn't a culinary class today, following the exam on the previous day. So, they decided to...
