Erika pushed herself away from Emily, popping Emily's reciding knot out of herself. The two girls stood up hastily, looking around for their panties before being caught.
That is when Cameron, a teenage boy one year older, came down the stairs... and almost missed the last step as he caught sight of the two girls, whose open shirts left their perky breasts completely exposed.
"What the...?" he began, wide-eyed. That's when his gaze moved from Emily's chest down to her skirt, which front had caught against her wet erection. While it had just lost most of its canine appearance, it was still jutting 2 inches upward, and had prevented the school skirt from falling back into place.
"Ew! No way!!!" Cameron cried out in surprise. Emily let out a small whimper and grasped at her uniform, but only had enough hands to cover her breasts. Her semi hard-on swayed with her movements, and some goo leaked down her length to splatter in front of her.
"Don't look!" she cried, pressing her thigh together in a coy fashion. But Cameron couldn't take his eyes off Emily's penis, fascinated. Erika noticed a small bump on the front of the boy's trousers.
"Ugh, what a pervert!" Erika shouted at the teenager. "If you're into that, why don't you take a closer look?" she snickered and pulled him by the wrist.
The boy tried to resist Erika but his shoe caught on the panties that were laying around, tripping him forwards. He fell on his knees in front of Emily, and Erika angrily shoved his head against the sticky semi. The goo's pheromones immediately hit Cameron's nostrils.
"What.. why..." he mumbled weakly against Emily's groin as he licked his lips without thinking, only to move on to the tasty member in front of his face. There was no reason in his brain anymore, just the urge to get more of this taste as he licked hungrily Emily's erection like a candy. She squirmed on her feet and let out a moan as she felt herself swell again to 3 inches.
Erika kneeled beside Cameron and patted the tent on his pants, making him whimper. He sucked on Emily harder. This began a chain reaction as she moaned loudly and a load of pre escaped her dick to fill his mouth.
"Drink up, boy!" Erika mocked as Cameron gulped down on a mouthful of goo, and within a moment his body started changing. Erika could feel through the fabric that his erection was maintaining hardness, but was becoming smaller and smaller, and his balls retreated into his body entierely. She rubbed his groin back and forth through the pants until they became damp.
"That's what happens when you get a little too excited... girl!" Erika laughed. Cameron whimpered lewdly with Emily's dick in his mouth, entranced. Emily's breathing was more and more erratic.
"I'm... I'm gonna..." she let out between two moans, closing her eyes hard and grasping at her breasts as a spam ran through her body. Cameron almost choked as his mouth overflew with cum, and Emily's hips started jerking, dislodging her dick from his lips while several ropes of fluids hit him in the face and on the chest.
He fell back on his butt, his front shirt drenched in cum and sticking to his chest, which revealed a growing pair of breasts pressed against the fabric. The wet spot between his legs was also fairly obvious.
"That'll teach you right, perv!" Erika snickered as she stood up again and put her panties back. Emily pulled down on the front of her skirt embarassingly to hide her once-again softening member. She buttoned her shirt and put on her panties, struggling to fit her dick back inside.
Cameron scrambled away and ran towards the boys' bathroom without a word in shame, though his body was still shivering with lust.
"Are you okay Emily?" Erika finally asked when the boy was gone.
"Y... yeah..." she replied with a tiny voice. In her panties, she could still feel the thing between her legs. "Why... why is it not totally gone, Erika?" she whimpered.
"Oh Emily... it's ok, don't worry", Erika said with a caring voice. I think it's because you put it inside me... But it's still very small, you don't have to worry about it I promise! You just need to be carefull now." Emily blushed, embarassed by the lack of control she had over her own body.
The two girls finished wiping themselves clean and walked down the hall to return to class; Erika's hand absentmindedly rubbed her lower belly. Her mind was finally relaxed, now that the mating urge had gone. She finally felt content and... full, somehow.
