>>110239 (OP)I for the life of me cannot find this specific comic. All I have is a vague recollection.
I remember it involving a girl with dark hair that was too shy to talk to a guy, and she had a roommate/friend that encouraged her to take a pill or eat something that lead to breast and ass expansion, eventually leading to weight gain in the end too iirc. Both her and her friend end up huge at the end, and the girl has more confidence thanks to her new body, and eventually approaches her crush.
I don't have an artist or anything, but I remember enjoying it a while back. Wish I had more to go off of.
