Yup I agree, most likely she did exactly what she probably planned from the start, which is to milk the lewd content for as long as she could, and then quit when she would otherwise have to start doing more sexual things. She got as close as she could without going against whatever " morals" she probably thinks she has.
But who knows these girls are so conflicted in their head, between their own thoughts, societal stigmas/ pressures, their family/friends expectations, that they flip flop daily on what they want to do. One day they convince themselves that they don't care what people think, the next day they become hyperaware of the stigma they are placing on themselves, the next day, they only care about money and willing to do what they weren't willing to do the previous day. It's all over the place, they basically live in a cycle of lies and conflict in their own heads about what they will and will not do. So it can change at any moment.
