As Erika straightened herself, she began walking down the corridor until she passed in front of the girl's bathrooms, when she heard lewd moaning. She immediately remembered she had sent Emiliy to catch Piper there.
Bursting through the door, she stumbled upon Emily laying on her back in the middle of the floor and moaning, while Piper seemed in a trance sitting upon her.
"Oh fuck no, you didn't," Erika growled in a low voice as she stepped up to grab Piper away from Emily. She met some resistance as the two of them were locked together, and pulled harder. Suddendly she heard a wet 'pop' as Emily's knot slipped out, and the two culprits sat there on the floor as they panted heavily, catching their breath.
"Girls, there will be some explaining to do after school. Meet me then at my house, and don't speak a word of this to anyone." Erika ordered in a husky voice.
Piper nodded embarassingly as she stood up and ran out to her classes.
"Now you..." Erika growled at Emily, who let out a high-pitched puppy whine in response. "You can't go around putting your goo into other girls in school! You'll draw attention to us."
"I'm-I'm sorry Erika! I couldn't help it... I went to talk to her and then she was onto me, I don't know what happened..." Emily sniffled still sitting in a puddle of juices.
"Now let's do what damage you've done," Erika said as she lifted Emily's skirt.
Emily's dick was still spasming between her legs, goo oozing out of the tip as it softened. However it wasn't getting much smaller. In fact, Erika's eyes widened as she witnessed the member thickening a little, and the tip reaching down and meeting the wet floor, while the two furry orbs underneath visibly swelled. Emily's beasts were also back to being close to non-existent, the front of her shirt clinging to a barely prepubescent chest.
"Look, you've made your situation worse now. You need to learn how to behave." Erika scolded her as Emily blushed and nodded. "And all that goo shouldn't go to waste..." she went on.
After all, Erika really couldn't show up in class looking truely like a boy. If she could ingest some of Emily's fluids, she would turn back into a girl, if only temporarily...
Erika leaned down and started licking Emily's wet thighs and dick, cleaning her up with her strangely canine tongue. Emily's sniffles stopped and she began squirming instead, almost as if she was ready for another go, but her member stayed mostly limp.
As she swallowed down the goo, Erika felt a warm shiver through her as her body changed once again. Her nipples pushed against her shirt as breasts swelled on her chest, and her monster cock and balls withdrew between her legs in a minute, replaced in her torn underwear by a familiar pussy. She grunted with satisfaction and she pushed Emily back.
"Ok now," Erika said with a feminine voice, "you don't talk of this to anyone, even Piper; I'll explain everything to them after school at my house. You're coming too, of course. Just go through the day as normal as possible, and we'll figure something out."
Emily nodded and she stood up, pulling her panties over her package, which barely fit anymore. There was a slight bump in front of her small skirt, but Erika was confident it would disappear in a minute and shouldn't draw unwanted attention.
Now they only had to bide their time and wait for the day to pass without issues...
