Most of the bara/yaoi images generated tend to swap the prompt"big breasts" to pectorals/moobs...

This concept makes generators interpret male's chest to female's chest allowing you to

give your dude huge milkers no matter what.

I suggest using this concept with a well-trained style lora since it's niche and often produces blurry images.

recommended weight is 0.5~0.8.

Of course, you can always use this to make more tomboy-ish images with short hair/masculine features.

use various prompts like bara,twink,skinny,toned etc in either general/negative section.
