is this what they meant when bro calls pookie bear accidentally

3 tomboys who grew up to be onee-sans

The photo referenced is of three young boys on the top and years later them crossdressing. I think based on certain facial features we can safely assume the top three people are also the bottom three people. Now whether they are boys or girls is hard to tell. For now with no indication that those breasts are fake, I think tagging only 3girls should be the correct approach.
