Growing wife

Your wife and you got a size transfer. Unfortunately they messed up and took too much mass from you, your life likes it.

The Nexus Labs Size Transfer machine. What looks to be a ceiling mounted Lazer beam can take any mass from one person, and give it to the other in any way. This procedure, while new, is incredibly popular all around the globe, especially with couples.

Many husbands were more than willing to give an inch of hight, or a bit of fat to thier wives or girlfriends, letting them get taller, or increase thier bust size, or thicken up thier thighs and rear. The opposite was also popular, with wives giving a cup size or two, or perhaps some fat to thier husband's to make them taller or add on to thier dick size. (But mostly add to thier dick size)

And while the waver you had to sign was the size of a small novel due to the experimental nature of the procedure 95% of all procedures went without flaw, and the flaws were useualy minor, such as taking an extra inch away or adding the mass somewhere else.

And of course with all good things many used it for the wrong reasons, paying debts with mass and creating unsafe black market Size Transfer machines, this of course led to some scary crime, people being drive-by shrunk down to microscopic sizes or kidnapping smaller people and recording them in fucked up situations.
