Growth Academy’s Shiori is all about AE.
Research Station M-00 has a girl that features AE. Her name escapes me at the moment.
Cowgirl Casino’s Ellie has a bottom heavy focused weight gain.
Fattening Career has a few girls that are pear focused in their gains. One in particular named Trista gains basically completely (at least for now) in her ass and thighs.
Filling up my roomates’s Sarah gains largely in her ass. There are one or two other girls that are gain similarly (though much less pronounced).
