Twilight's Very Unusual Night Out

After Twilight had completed the "beta test", she knew that it was time for the "alpha test" and she was so excited to try the spell out on herself for the very first time.
Twilight left the comforts of her castle and went to visit Doctor Hooves to try the spell out on him.

"I hope this spell does what it's supposed to do", Twilight said to herself

As she approached Doc Hooves' place, she started to get nervous and scared.
She never attempted to do anything like this before and was unsure how it was gonna turn out in the end.
Twilight walked up to the door and rung the doorbell. She waited on the door to open as she stood there with her arms crossed over each other.

A few minutes went by and there was still no answer! Twilight thought that this was a waste of time to perform her alpha test on Doc hooves as she walked away from his door.

"Can this day get any worse?", Twilight asked herself

She looked up above her and noticed a dark raincloud looming over her. Twilight looked closer and saw a gray, blonde headed mare bouncing on the cloud above her.

The cloud bursted with a surge of lightning strikes and all of them struck Twilight right where she stood!
"I just had to ask that question, now didn't I?", Twilight said sarcastically.

The blond headed mare was nopony other than Derpy Hooves!
she flew down off of her cloud and went to check on whoever was below the cloud to see if they were okay or not. Twilight dusted the smoke dust from her mane as Derpy landed in front of her,tucking her wings away ever so lovely like.

"Are you ok Twilight?", Derpy asked Twilight very casual like.

"I'm fine Derpy, just shocked to see you here, Twilight replied calmly.

"Well thats a relief, I thought you were injured", Derpy said so coyfully.

"I'm fine Derpy!", Twilight Sparkle shouted with a hateful tone towards the small breasted,and walleyed gray mare.

"Do you know if Doctor Hooves is home?", Twilight asked Derpy with a smile.

Derpy looked over at the time traveling blue phone booth and looked back at Twilight with a scrungy face. Derpy didn't know what else to do, so she distracted her with a smoke bomb! Twilight placed her hands over her eyes to shield her eyes from the blast of bright light and a grey puff of smoke filled the small area they were standing at. Twilight looked up after the smoke cleared and noticed Derpy was gone! Twilight started searching for Doctor Hooves high and low, trying to find him so she could test the magic spell she had learned in her studies back at the castle. It was only a matter of time before her magic slowly builds up and forces her body,her boobs,and her ass to expand until the magic was fully released or until she found another unicorn to help her out and defuse the magic spell! A few hours Later, Doctor Hooves slowly emerged out of his house, but Twilight didn't see him because she was distracted by a tingling but pleasureful sensation happening inside her breasts! Her breasts started to grow and fill up with milk,making twilight moan in bliss from her growth! Twilight's breasts kept growing and growing,making her bra get smaller and tighter!
