Can you tell me how i could become thicker, "plump" ,more in my butt and breasts?

Body Makeup: Three Ways: Surgery. Exercise to build pectorals and buttock muscles (don't know if that will get you the plump you're asking for). Weight gain- con is that you won't be able to decide where the fat goes, eventually if you keep gaining enough you will get there, probably at a gain of everything else. Weight gain is definitely not recommended.
