Futas and Betas

Futas are born into this world from a beta and a sire. The sire gives the sperm, while the beta gestates and gives birth.

It isn't until the age of maturity (age 18-age 21 depending on when it becomes legal in your country) that futas are able to fuck or be fucked.

Futas have a cock, balls, and pussy, however their relative size can change compared to how they're used.

A futa who fucks a lot is an Alpha

As a result, their cock and balls get bigger. Their pussy shrinks to a tiny size. Sometimes it's necessarily to fuck them anally if their pussies are just too small and a futa wants to dom them. However, Alphas are usually highly resistant to getting fucked. They want to do the fucking.

A Beta is a futa that gets fucked a lot. Their cock and balls shrink to make room for a growing pussy. When beta enough, pregnancy is possible.

A ballbusted beta is a quick way to turn an alpha or an undiverged futa into a beta. Basically, the testicles are crushed, causing a futa to quickly become a beta.
