There's a short film called wedding cake by magnetfilms on YouTube which feature's a cake topper couple that can manipulate their surroundings with frosting. In one part the husband is watching a ad with big boobs and later on trying to fix his wife's stain he ends up using frosting to make her huge tits. Plain and simple. Nothing huge outside her tit size Although if you asked me I'd might have preferred the shop keep filling her up with the piping bag/pastry frosting cone because why not a direct mouth or ass full like that cat girl video with the cream puff machine would be very lewd and a fun inflation breast or blimp (there's a fanart idea for you if anyone gets the vibe to make her big and round)
