Emily looked at the mess she had made in the bathroom stall. The goo was everywhere, and she didn't get the chance to gulp it down to turn back into a normal girl.
"Maybe I can lick some of it..." she pondered and blushed. The floor was disgusting, but parts of the wall looked clean, save from the cum splashes.
She leaned forward and extended her tongue to lick one spot. The taste was better than she thought it would be and she unconsciously started sucking hungrily on the goo as the pheromones filled her nostrils. A warm sensation filled her chest and groin, but no change yet... It wasn't enough.
Emily kept licking the stall's wall, bowing lower to follow a rope of cum and ingest as much of it as she could. She felt something shift between her legs as the soft member began shrinking, pulling back into her; at the same time, her nipples swelled and small breasts filled the front of her blouse, just barely.
At this point she was running out of acceptable surfaces to lick and all was left was the toilet seat, pipes, and the dirty floor. She slipped a hand in her skirt and touched between her legs: there was still a one inch bump and a furry nutsack in place of her normal girt parts!
The toilet door slammed open and Piper and Riley barged in, immediately catching sight of Emily's predicament.
"Eew, what are you doing!" Piper giggled awkwardly while Emily pushed herself away from the wall, her hand still in her skirt.
"Emily you're so naughty! Does Erika knows you're here touching yourself?" Riley teased.
"I'm... I didn't do anything!" Emily started crying.
"Aww it's ok, we won't say anything at all", Riley added with a hint of guilt.
Emily threw herself in her friends' arms with a sob. "I'm hungry, I want to go home! I hate school..." she whined as she nuzzled against their swollen chests. Both Piper and Riley felt their heartbeat speed up for a second, but played it nonchalently, in spite of the enticing pheromones hitting their noses.
Piper couldn't help but remember when she had sat on Emily in a different bathroom, their bodies pressed together as she discovered the wonders of the canine dick inside her. If only they were alone to do it again... It felt so, so good! It's not like she wasn't already pregnant anyway.
She instinctively adjusted the front of her shirt over the discreet curve of her belly.
"C'mon now Emily! It's lunchtime anyway, Erika is probably waiting for us", Riley said firmly, bringing Piper back from her revery. They pushed their younger friend towards the sinks to help her clean up.
Riley saw her own reflection in the mirror and noticed her dark areolas were partly visible through the white fabric of her shirt, but there was nothing she could do about it since her bras didn't fit anymore. She wondered how big her breasts would get with the pregnancy? Erika bred with her but didn't explain anything about it... Maybe after school?
The three girls soon exited the bathrooms to go to the cafeteria, giggling a little too much to hide their embarassment along the way. They quickly reunited with Erika again, who could smell the hint of sex and hormones all over them. "Good" she thought to herself, "the more pent up they are, the more fun later when we get to play together".
At the same time, she did wonder what they had been up to. She didn't like her alpha status challenged, after all. There was also no sign of Cole and Sam - although they were in different classes because the teenage secret couple was older, Erika would usually see them pass by the halls. Maybe she could check on them before lunch break was over... but that would mean leaving two horny lesbians and a naive pup without supervision.
On top of everything, the effect of her own goo she had ingested before the swimming lesson was wearing down, as the swelling inch in her panties was reminding her.
