Due to a bimbo eating a radioactive hotdog it caused her to become more bimbo and more curvy and cause of that she accidentally bumped her butt into a man.....he turned into a big bimbo like her too as more and more bimbos bumped into others infecting them too.

All it takes it a touch from the big curvy bimbos to infect someone and make them change immediately.

The virus gives you massive breasts the size of basketballs, slim waist, very wide hips, large plump lips with a massive plump bum with also their hair growing long and blonde. They grow taller with long fake nails too and their clothes turn skimpy and pink.

also gain the speech of a bimbo using 'like' and 'totes' alot.

(Maybe your in the middle of the virus, at the start or maybe where it began.)
