"Oh god what have I done!" April gasped as her boobs were pushing out once again making her moan in delight and frightened.  As her breasts grew larger by every passing second, her moaning abruptly stopped. The pleasure just disappeared, as if her body got use to the growth and simply withdrew it. April tried to massage her increasing breasts, hoping the sensation would return, but her arms barely reached her erected nipples, leaving them useless. The floor beneath her started making creaking noises. She lived on the 3rd floor of the dorm, so that was a problem indeed.

She started to panic she didn't know what to do. Just as all hope was lost, her door swung opened with Chelsea running in. "Okay now wha- Holy shit!" she stared at disbelief at how large April's breasts have became. "Chelsea help me up" April pleaded as her breasts pushed outwards almost within a foot of the window. Chelsea walked over, blushing from her breasts. "But you look so cute like that!" She smirked as she squeezed on her rock hard nipples allowing the pleasure to return. "Wait..." she moaned from the intensity. Her breasts slowly halted filling up most of her dorm room causing the floor to make loud creaking noises.

April suspicion was aroused. Was Chelsea bi? I mean she does have a boyfriend, but what she just said proves it?  "Just look at you" Chelsea said as it snapped April from her daze "You love this don't you?"She poked her nipple making her moan. She walked over to the kitchen and picked up the flask filled with the green goop. "If this happens after just a small overdose think what will happen on larger scale!" This made April struggle to no avail.

"Chelsea look at me! I've filled my entire dorm basically and I'm gonna need reducti-" she paused as she noticed the black book not far away. It didn't matter just as long as they had the book; they can shrink her heck make her even larger and she could return to normal. A grin crept up on her face. "Well as long as we get back to normal before tomorrow…."

Chelsea cheered in happiness and put the flask to her mouth. She sat in between April's cleavage to make sure she got to watch the experience.  "Ready?" "As ever." She sighed and opened her mouth. She slowly poured all the ooze into her mouth chugging it slowly. As she gulped the last of it an utter silence filled the air. Nothing happened. "Why are they no-""Wait!" April shushed her companion. As she interrupted her a slow rumble filled the air which increased in noise. The dorm started to shake with her breasts making them shake causing the floor to give way plummeting them floor after floor with her breasts cushioning the fall.

As other people started to investigate what was going on, it was too late. Her breasts pushed outwards at a massive rate, sending them flying into the walls breaking down wall after wall tearing the dorm up from the inside. She rose quickly being from as high as the first floor to as high as the dorm within seconds. April's eyes soon dilated wildly and screamed from the pleasure she received from her uncontrollable growth increasing its speed.

Chelsea clutched on to Aprils breasts as hard as she could. Although she wished to help her friend, she couldn't do much right now. If she attempted to leave her cleavage she could fall off.
Her breasts over passed the college itself and soon started to overlap town after town, city after city. After just a few minutes her breasts overlapped the entire state and started to overlap many other states eventually overlapping the U.S. itself.


Meanwhile in Great Britain

This is BBC News

"And that's how Sir James banged an American actress." A reporter told his co reporter. "I do say that is charming indeed… and in other news an American girl's breasts have grown at a rapid rate and has covered America and should be at Britain any moment." "It's always the yanks isn't it?" and just when he said that, Aprils breasts collided with the building destroying it on impact.
"April are you okay?" Chelsea yelled to her as she saw her squirming for a second. "Chelsea, this feeling is unlike any other!" She yelled happily to her friend resting within her cleavage "It's hard to explain, but I can feel everything under me!"  She kept squealing as her breasts continuously overlapped oceans, mountains, and buildings.

A sudden jolt abruptly stopped her growth allowing her to gasp for air after screaming for a while. Chelsea managed to get out of her cleavage and slowly climbed her way to her friend sitting there. "So how was it?" Chelsea grinned as he sat next to April. She kept huffing "A…once in…a lifetime..thrill." she then took a deep breath. "How high are we exactly?"

Meanwhile in deep space

Bob the astronaut was just returning from his trip to the Moon. "Houston, I'm approaching Earth, I'm on the far side of the earth and should make a decent soon." Static filled the air "Houston?" he tapped his mic and shrugged it off. Just as he was about to make his descend, a large shadow blocked the sun. "What the-"the aircraft kept rotating as his eyes went wide. "Just what have I missed in the past 8 days? He mumbled.

April's breasts filled most of the western hemisphere as well as land in Europe and Asia. Her nipples were as large as the U.S as her height toppled close to the world itself.

A lone figure stood floating high above April and her massive breasts. "Tsk, tsk, I warned her." Dday shook his head. "However she seems to enjoy this so I guess this is her problem to deal with." His arm reached outwards, allowing the black book to appear in his hands.  He placed it within his coat and grinned.  "This turned out better than I thought." With that he opened up a dimensional gateway and left.
