As the two bimbos kiss, the forms begin to glow a solf pink. Their curve began to grow to double their size, while their waists shrink to a point where their organs there become useless, thankfully the problems that come from that would soon be made irrelevant.
This was made clear as their hair, skin, and clothes started to become pure pink. They where turning into the very concept of a bimbo. They were bimbo, there clothes were bimbo, their fluids were bimbo. Every atom that made up their bodies were bimbo.
The bimbos broke the feedback loop thanks to their growing assets, but at this point it was to late. The concept of bimbo was spreading to all objects near them. So all will become Pink, Curvy, mindless, and orgasming with every atoms of their bodies. So, even the Earth itself was to become a bimbo.
The only question now is who do you wish to follow during this time.
