Erika's fur and balls receded between her legs and out of sight. Her canine penis went soft into her sheath, which was shrinking back into her body. She was rubbing her face and mid-length hair to make sure there was no trace of cum left on her when several classmates made an irruption in the room to occupy the other stalls, chatting and giggling together. She heard Melissa's voice from behind.
"Erika! I hope you're feeling better now? You got me worried. You were all quiet and distant earlier, I thought you were ignoring me" her friend said with a pout.
"Uh, sorry, I..." Erika started, when Melissa entered her stall and hugged her from behind, giggling softly and inadvertently brushing past one of her shrinking teats, squeezing her body right under her swollen breasts.
"Oh wow, you sure have grown a lot, I did not notice before! Glad I'm not the only one now..." Melissa teased.
Erika laughed uncomfortably, tugging discretly on her swimsuit to make sure her subsiding bulge wasn't noticeable.
"Thanks Mel! Well I was done with the shower actually, so I'll see you in a moment" she said as she wiggled out of her friend's embrace and hurried to the changing rooms before anybody got there.
She wrapped herself in a towel and removed her swimming suit. Her body seemed back to normal, though her friend's touch had made her feel strange and her clitoris was poking out of its hood, the fur too short to conceal it. A tiny hole was still visible in the middle of the button, a remnant from her canine member. The sensation of Melissa's boobs pressed in her back flashed through her mind and her mutant clitoris tingled, causing a tiny bead of fluid to emerge from the slit.
"What has gotten into me?" she whined as she stepped into her skirt and pulled it up, hidding her genitals from sight. She buttoned her shirt and found the excitation had prevented her breasts from shrinking back entierely to A cups; they looked like an average B, but felt swollen and sensitive to her touch, her nipples poking through the fabric. Erika was adjusting her shirt over them when Melissa joined her in the locker room.
"You really need to get yourself some bras, girl! she giggled.
"I know!" Erika replied. "I haven't had the time since my latest... growth spurt" she said, blushing furiously.
"I know the feeling, I've changed bras twice since the beginning of the year. I still have my old ones, maybe you could try them out, see if any fits you!" Melissa said with a wink.
"Yeah? That would be nice, thanks!" Erika smiled.
"Perfect! Want to come over to my place and sleep over tonight, then? Your mom told my mom you'd be on your own this weekend and that I should invite you over.
"Sure!" Erika said enthusiastically before biting her tongue. With her current condition it was a risky situation, and she had not thought this through.
"Great then!" Melissa giggled excitedly, her breasts jiggling as she was putting on her own school uniform. Erika could still feel the strange warmth over her moist, swollen clitoris, and she tugged on her skirt uncomfortably.
"Let's get going or we'll be late to class", she said with a flushed face before they both grabbed their bags and exited the locker's room.
