Erika crawled across the bedroom to get away from Max, but he was still stuck inside her, now facing the opposite direction. She threw herself against the door to shut it as it was about to open. There was a pause.
"Are you alright pumkin?" Erika's mom asked through the door.
"Y-yes!" Erika tried to reply with as much confidence as she could muster, though her voice weavered when her swollen breasts pressed against the cool door. A spasm ran through her body, and she felt them getting a little heavier, while her tummy got slightly rounder. "I'm okay! Just changing from school clothes..."
"Who's in the bathroom?" asked her mom.
"It's Emily! We... we have homeworks to do together," Erika made up on the spot, "and her mom is picking her up later. She's not staying for dinner." She tried to squirm free of Max, and only managed to squeeze some goo out, which dribbled down the inside of her thighs under her school skirt.
"Okay sweetheart, let me know if you need help then." The sound of her mom's footsteps receded from the corridor.
Erika let out a sigh of relief, and just when she began to relax, she heard a wet pop as Max finally slid out of her, his canine dick slowly disappearing in his shaft. Erika stood up on her shaky legs, examining her body. She looked four months pregnant, with canine teats poking outwards on her lower belly. Her human breasts were protruding obscenely out of her open shirt.
"I guess I need to hide all that until I find a solution..." she mumbled to herself.
She wiped herself with tissues and went through her drawers until she found a simple ample white t-shirt, some pink shorts, and a sky blue hoodie. Once she put on her outfit, she looked fairly normal, thanks to the bagginess of the clothes and the big kangaroo pocket in front.
"Can I come in?" Emily asked behind the door.
"Yeah, sure!" Erika replied joyfully. "I was just getting changed."
Emily came into the room as Max walked out, and she wrinkled her nose a little. "I... I think you should open the window, maybe."
"Don't worry about it, it's probably just your canine sense of smell, there's no way my mom figures anything out", Erika giggled. "Let's do our homeworks for now."
The two friends got to work, sitting on the floor and the bed. Erika realized she didn't think so much of boobies and that sort of things when her belly was full of goo. It was still exciting, but not so much distracting.
Soon enough, homeworks were done and Emily's mom came to bring her daughter home. Erika's mother called her for dinner. It was pizza night apparently, probably because her mom was feeling a little lazy. She even asked Erika if she wanted to eat in front of the TV, which would rarely happens when dad was around.
As she ravenously ate her pizza slices, Erika felt warm contentment radiates from her belly. She hadn't noticed she was so hungry! She had barely finished one slice that she was grabbing another one. After she was finished, she relaxed on the couch, focusing on the soap opera her mom had put on TV.
Erika sat back and slipped her hands in her kangaroo pocket, and realized there was not much space left there. Very slowly and discretly, her hands still hidden, she cupped her belly with them both, and she felt shapes push through the fabric under her palms - hard teats on top of fleshy mounds. She tried to keep a straight face, but her cheeks turned hot and red. Fortunately, the room was somewhat dark at this point, and her mom was only looking at the screen.
Suddendly, Erika felt a stir, and the fabric under her hands became a little more taunt as her belly grew another inch. She looked down, and saw her chest also expand under her eyes, the nipples so large they were almost poking through both the shirt and the hoodie. Then it stopped. Erika felt a warmth emanating from her breasts, and saw two growing wet spots forming on the fabric. She was leaking milk!!!
