"I'm so... full..." Erika grunted as she stood up on shaky legs, cum running down her thighs and onto the grass. She tried to button her shirt, but could only do the top section. Even then, her chest was painfully constricted inside.
"I need to get home quick!" she lamented to Emily, who was removing the shreds of her panties.
The two started walking hastily, or at least as fast as Erika could go without getting out of breath. Emily felt like she was on a cloud after emptying her balls into her friend's belly for the second time in the day. Her body was still electric, pleasant shivers running up and down her body.
She didn't realize on the way to Erika's home that the milk she had ingested was still in effect. Of course she was a little uncomfortable in her school uniform, but she paid no mind at her hips stretching her skirt a little more with each step, or that her breasts were filling her shirt more snuggly. She couldn't help but notice though that the chunk of meat between her legs had gotten heavier, giving her a more awkward gait as everything felt like it was slapping around more uncomfortably than before at this rapid pace.
By the time they were home in Erika's bedroom, Emily's feet were hurting from walking in shoes a size too small.
"Do you have, uh, spare clothes or something?" she asked Erika in a tiny voice, removing her shoes and pressing the front of her skirt as though it would flatten her member into oblivion.
Erila nodded and went through her drawers, finding bras and a dress that Emily could borrow, and the most comfortable underwear she had. The dress was flowery and ample, a cute summer dress that suited Emily's innocents looks. As Erika helped Emily adjust the bra straps, Emily felt herself blush under the touch of her friend. She had become so excitable! It had only been a moment and yet. She needed to get rid of the thing between her legs! It barely fit her panties anyway.
"Uh, Erika, can you milk the goo out of my thingy so I can drink it and turn back into a normal girl again? My mom needs to pick me up soon and... and..." Emily's voice broke.
"Ssure! Yeah I can do that, let's find an empty bottle or something in the kitchen then, just give me one second," Erika replied without hesitation.
Erika removed her dirty school uniform to find something that could hide her belly. She settled on an ample white t-shirt and long, oversized pale yellow hoodie that went past her hips. She put on the largest denim shorts she had - which looked more like a mini-short on her right now, disappearing under the bottom of the hoodie as well.
They both went down to the kitchen and sat at the table with some snacks. After Emily emptied the juice bottle into their glasses, Erika took it in one hand and lifted the front of Emily's dress with the other. Emily's penis was tucked upward in her panties and sticking past the waistband because of its length.
"We'll put the goo in the bottle so you can drink from it whenever you need it", Erika explained. "That way you won't have to worry if I'm not around to help milking your goo."
Emily nodded, keeping the front of the dress lifted and closing her eyes to avoid looking down. Erika didn't seem to react at the size of Emily's penis as she pulled down on the waistband. After several days and exactly one spray of potion, one impregnation of Erika, and several gulps of milk, the one incher was definitively gone, now replaced by a very thick two by four member.
Erika grabbed it with one hand and began stroking. The two friends watched as it stretched forward, quickly hardening under Erika's now experienced touch. Emily opened one eye and looked, horrified yet panting audibly, as it reached over six inches and started becoming more canine in nature.
"Now the bottle, before the bulge gets too big", Erika said calmly, guiding Emily's erection into the bottle and past the knot. Emily's penis started leaking pre, smearing it around the sides of the bottle. It began throbbing rythmically as Erika jerked the bottle around. A lustful whimper escaped Emily's throat when she felt her knot fill the bottle. The doggy dong attached to her groin was making her feel very good all of the sudden; she couldn't help herself.
Erika leaned over Emily and began kissing her neck, and Emily immediately turned to hungrily kiss her back on her lips. Her right hand reached towards Erika to touch her belly through the front of the hoodie, and she felt the vague shapes of a pair of teats. Moving her hands downward, Emily lifted the hem of the hoodie slightly and cupped the mounds of flesh on Erika's lower belly. They were probably filled with milk, gravity giving them the superficial shape of small breasts, but the nipples were much longer, ressembling swollen canine teats.
Side by side, Erika and Emily squirmed on their respective chairs, the two girls moaning as the fondling and jerking intensified. Erika's lower teats were protruding from under the hoodie and Emily was fondling them, while Emily's erect member was spurting pre in chaotic bursts inside the bottle that kept it prisoner. Their hearts were beating faster and faster.
"I'm home sweetie!" the two of them heard further away from the hallway, jumping in surprise while the door closed audibly. Erika's mom had just returned early from work!
The two horny girls immediately shifted away from each other, straightening themselves on their chairs and pulling themselves against the table. Erika's lowest pair of teats were visible under the table though, poking down from under the hoodie. Erika's mom came into the kitchen just as Emily's excited member lifted the bottle without any help. It knocked the underside of the kitchen table with a small bonk.
"Oh I didn't know Emily would be here as well!" Erika's mom said before taking a pause. "You've grown so much since last time you visited. Such a big girl now! Your mommy must be so proud."
Emily's cheeks turned red, leaning more over the table and her half-eaten snacks as her heart was still racing. She was unable to pull her dress down and over the erect bottle. Hidden under the table, the thing between her legs couldn't stop spasming, spurting forth splatters of goo inside the bottle and yearning for relief.
