Having gotten into a heated discussion about what to play Greg and Martha the middle aged parents, Susan the 12 year old girl, and Jacob a 6 year old boy decided to play Monopoly. Jacob had wanted one of the new TF monopoly, but that cost a bit too much and Greg didn't like the magic involved. At the table they all sat down and Greg uncovered their old monopoly game board and then the board levitated out of the box with the words "Boobopoly" on the game board. The board itself seemed more or less unchanged.
Jacob said "Cool! Magic Monopoly!" Greg and Martha were freaking out a little and Susan was blushing a bit thinking about this games theming and her own budding boobs. Each of them selected a game piece that were also unchanged, and then 1500 monopoly money floated towards them.
"Well at least the game itself is the banker..." Greg muttered before noticing that the bills had MM on them instead of trains. Then he felt a pressure build up in his chest as his buttoned down shirt popped as boobs quickly grew and flopped down onto his lap. Something similar happened to each of his family. Martha who was good with numbers thought for a second and said "... 1500 MM... milimeters 150 cm... or 1.5 meters worth of boob or to imperial... I think we all have roughly boobs that are five feet large."
Susan was a bit quiet as she was staring at her monstrous cleavage, but Jacob asked "Eww... So I'm a girl now?"
Greg said "No, I think we all just have breasts... Jacob you know how these games work right? Is there a way to turn this off?"
Jacob said "I think we just have to play till the game ends and then it'll revert."
Greg scowled and then said "Well youngest first. Go on and take your turn Jacob."
Jacob threw his dice and got a 5, his piece went to the reading rainbow which he bought and then Jacob felt his breast shrink a decent amount to the point where his breasts were now closer to 4 feet rather than 5 feet. Greg smirked a bit getting how things were going as he threw the dice... and also rolled a 5. Which meant 25 MM of his boobs went straight to his son. Normally he'd curse his luck, but Greg felt this was one game he didn't really want to win.
