History was usually the notorious "boring" subject (as much as one could be "the" when all share that characteristic), but "boring" had very little meaning to Jen anymore.
Let's see... This class had Laura, of course. Audrey would be here as well, so Jen should get her tongue prepared for that. She was fairly sure at least two of the six girls who had merged in her earlier class were enrolled, but how their collective schedule would be affected in the new reality was unknown. Was she missing anyone? Not that she could tell, but she had to see. She knocked on the door...
As expected, her tongue started to lengthen in the direction of Audrey's seat, but Jen was more surprised by something different. She recognized the girl who had opened the door.
"It's Jen!" Melissa confirmed for the teacher, Mr. Hernandez, whose own penis was not immune to Audrey's attractive ability it seemed. Jen floated in after Melissa and confirmed that the people she listed were all here. Plus one more.
She had actually seen Melissa's transformation, though hadn't recognized her at the time. Melissa was one of the girls the principal had... infected... in the hallway. She was the one with the dicknecks, and still had one of them in her lower pussy as well as the one between her shoulders. She had removed the one in her ass, though, probably so she could sit down more easily, though Jen could easily see where it went. As she walked past others in the class, she saw Melissa's third dicknecked head embedded in another girl, Kimberly's pussy, beneath the latter's desk. Kim idlely pumped Melissa's head in and out with one hand, taking notes with the other.
Jen's seat was right between Laura and Melissa, as it happened, meaning Jen's tongue was stretched across the classroom to stay inside Audrey's cunt. To be fair, some of the boys' penises were stretched longer. "Um," Jen asked, "where's my chair?" The class all turned to look at her, confused. Then Jen realized with an, "Oh, right!" Chairs were made for people who would fall down without something to support them. Jen had no need for one in this reality. She assumed a more-or-less "sitting" position in the air behind her desk, and Mr. Hernandez resumed his lecture.
Melissa leaned over and whispered to Jen, "You alright? Was that poo big enough to scramble your brain or something?" Jen blushed hard and turned her head away. "Here," Melissa continued, "Need a dick to focus, or will Audrey's cooch be enough?" Jen looked back to see Melissa pull her head out of her shoulderpussy, which was swiftly replaced by yet a fourth. She must be another with a recursive ability like Laura's, though more easily controlled it appeared.
"I-I'm fine..." Jen replied, a bit intimidated by not only the cocks' two-foot length, but the fact that if she was right, her pills' transformative effects were also passed on through semen.
"Suit yourself." Melissa turned and offered her head to the girl on her other side, who didn't hesitate to accept.
Jen turned back toward the front just in time to catch Kim's transformation from Melissa cumming inside her. It was a simple one, but weird: Her eyes closed and bulged out a little, being replaced by extra mouths. All three mouths got covered in a bright red lipstick. Unbuttoning her blouse, she revealed yet two more mouths replacing her nipples. Then she went back to taking notes, so she must've had some way of seeing.
Laura giggled and pointed out Kim's transformation to Jen. "Yeah," Jen whispered, "I saw it."
"Well, what are you waiting for, then?" the scientist asked, "Let's transform some more."
