Quick sketches of three "big/fat/chubby" people?

Hey I was hoping to do quick sketchies of a few bigger people today. No skinnies or muscular today, I am being commissioned for 2 skinnies and one muscular on another site and i'm kinda of tired of drawing those body types for now so...
I'm thinking two girls (because sorry, the more circles, the more fun it is to draw) and one guy?

Just quick sketchies.

Please and thank you. Please link me to where I can see refs of you ^.^
