One afternoon, The Doctor and Amy were relaxing and having a laught in the TARDIS. Amy always wanted a bit of a chest, but was disadvantaged due to her not having much up there. Sure she had nice legs, but it were breasts she wanted.
So Amy asked an awkward question.
"Doctor, you have lots of different devices on this ship, and I though maybe you had something that made human er.... breasts bigger!
She said, incredibly awkwardly.
Fortunaltly for her, this seemed to be a normal question for the Doctor, who disappeared down one of the passage ways from the vast control room.
He returned after what seemed like an age to Amy, who was beginning to think that the Doctor had run off so he would not have to answer her question.
"What have you got?"
Asked Amy.
"Well, you see, I once met a wise old man, who found me Jelous of a subject at the academy on Gallifrey that a friend of mine had learned, but I was sadly not there on the day."
Started the Doctor.
"He gave me this, it transplants an item of someones memory, and plants it into yours. Perfectly safe."
He lied.
"But I don't want someone else's memory, I want bigger breasts!"
Whined Amy.
"Oh Amelia, I modified it to make it replicate physical things, including breast size!"
Enthused the Doctor, with a chuckle.
"Thing is, I can only use the body of those who have been inside the TARDIS, but thats hardly a problem, I know just whose to replicate!"
The screen on the device displayed Peri, Companion to the 6th Doctor, and then zoomed to her ginormous breasts.
"Perfect!"
Cried Amy, barely able to keep the exitment out of her voice, her breasts were going to be massive!
"It needs to be left overnight to charge, so we can get started tomorrow."
Said the Doctor, who went under the control deck to the power source under the console.
Amy had an Idea, She would tamper with the machine, to give her even bigger breasts!
