Simply put, the bettererest a chuuba is with collabs/offcollabs/socially adjusted a chuuba is, the more she is likely a whore. The more she is probably getting fucked. The more she is also likely to be menhera
That is why you should stick to socially isolated/inkya chuubas. They are most likely not whores.
There is no exception to this rule, there is not a single chuuba exempted. This is a universal rule.
