Erika did not listen to a word from her English teacher, thinking hard on how to cancel her plans for the night instead; but she could not find a way out of it - it worried her. She had to attend the sleepover, Melissa was her only friend, and she didn't want risking upsetting her. Beside, she really liked being around her!
Yet she was anxious about staying at her friend's place, considering the fact she had to squeeze the strange white goo out of her canine member every few hours to keep from turning further into an animal. Maybe if she could sneak into Melissa's bathroom for a moment to take care of herself it would work out alright, though.
When it was time for lunch, Erika stopped by the bathrooms because her bladder was full, and almost peed on herself when she realized the stream of urine was aiming more upward than downward... When she looked between her legs she saw that her clitoris had grown again a little more like a dog sheath since the locker rooms, and she was peeing from there.
She couldn't focus in Music either, as she was becoming hyper-vigilant of the ongoing changes in her body. Her breasts were slowly but surely swelling to B cups again, and her genitals were fleshing out. It didn't help that Melissa spent a lot of time around her, and seemed increasingly clingier as the hours passed.
Her last class for the day was Science, and seemed to last an eternity. Erika was doing all she could to keep a low profile, but she was becoming more flustered by the minute. The school uniform had become a tad too small since her growth spurt the previous day. Her breasts were swollen and sensitive, dark nipples pushing against the fabric of her buttoned shirt. Soon enough several rows of teats were doing the same.
Erika crossed her legs in an attempt to keep her canine balls from descending, but she only managed to push the whole package upward and her sheath rubbed against her skirt's waistband. In an instant the furry orbs expanded generously while the canine shaft became thicker.
For some reason, Melissa seemed agitated as well. While she was focusing on the teacher and blackboard, her breathing seemed a little erratic and a drop of sweat was running along her collarbone. She also looked like she was sitting closer to Erika than a moment ago. Erika looked at her friend absent-mindedly playing with a lock of her hair, and wondered if she was influenced by her new condition like her dog seemed to be.
Melissa's bead of sweat travelled from her collarbone to her cleavage and disappeared between her breasts. Erika felt her canine member stir from the sight, the pointy end pushing under her waistband and poking against her tummy under the shirt. She was still confused as to why Melissa was making her feel like that, and was both craving it and fearing it.
Erika discretly grabbed her bag and pressed it against her body on her knees to better conceal her growing erection. Melissa looked at her with a strange light in her light, asking if everything was okay.
"Yeah, I just can't wait for school to be over, is all" whispered Erika.
"Me too! I can't wait for you to come over tonight, it's been such a long time since we've done this! I've missed you..." Melissa said with a longing in her voice that made Erika shiver.
Students were packing their things as the class was ending, while she could feel a wet spot forming against her waistband and shirt.
