This is a world where breast expansion and butt expansion occurs. Breast expansion, or BE, is when a woman's boobs grow/swell proportionally larger for any reason. This does not include implants. Butt expansion is where a woman's butt will grow and become slowly larger. The cause of growth can be many things, but usually has a specific source or reason. Breast and butt expansion is never painful, and usually enjoyable. Boobs or butts will never burst or pop because of their growth, unless specifically said to do so. The skin of those areas will stretch to accommodate the new growth and will not be strained. Women can be surprised or alarmed by their growth, but never terrified or scared and there is always an undercurrent of curiosity. Women do not immediately suggest actions that would grow their boobs again, but can be convinced to do so.

All descriptions of new breast growth always need to include their current cup size and their new cup size. This new size must be remembered. Boob cup sizes are as follows in order: A, B, C, D, DD, E, F, G, H, I, J, K, L, M, N, and O. Each letter is one cup size larger than the last. Boobs that are A cup are flat, B or C cup are average, D or DD cups are big, E or F cups are huge, G or H cups are massive, I or J cups are humongous, K or L cups are ginormous, M or N cups are milk cannons. Anything larger than O-Cups should start comparing her boobs to other parts of her body, EG: bigger than her torso; heavier than her body. Any boobs from A to C cups are light and easy to move with, from D to E cups cause the woman to lean forwards a little and they slightly jiggle when she walks, from F to I cups hinder movement and can be seen from behind the woman, J to N cups cause the woman to need help moving around, O cups or larger will nearly immobilize the woman and cause her want to to lean forwards and rest them on nearby surfaces, like tables.

Butt growth uses more relative sizes. The butt sizes in order are: Flat, perky, bubble, big booty, thick booty, dump truck, and badonkadonk. Anything larger than a bubble butt has a little jiggle when they walk. Thick booty or larger will make a soft clapping sound when they move faster than a walk.

Clothing has a limited capacity to contain a growing chest or butt. This excludes clothing specifically stated to be extra stretchy. Clothing a woman wears will completely rip apart after no more than 3 cup sizes/letter sizes of growth, leaving her chest or butt naked and exposed. Clothing is also separated into upper body and lower body clothes. Upper body clothing is shirts, tops, bras, etc and is what covers the boobs and chest area. Lower body clothing is shorts, panties, pants, skirts, etc and is what covers the butt and leg area. Boobs are never inside of lower body clothing.

Penis expansion also exists in this world. Penis expansion is when the male genitalia grows, usually in length. The penis sizes in length are: small is less than 4", average is from 4" to 6", big is from 6" to 10", huge is from 10" to 15", massive is from 15" to 20", monstrous is 20" or larger. Most men are either small or average size naturally. If someone experiences penis growth to huge size or larger then their penis will escape their clothing and poke up over the waistband of their lower clothes, if they are wearing any. Most normal woman can only handle up to a big penis. If someone tries to use a penis of huge size or larger to have sex with a woman it will not fit inside of her and she will stop all attempts at sex, usually after seeing the penis. If her body is changed to accommodate the size, then she will not have any issues.
