I am with George and Andrew here. This is not like Ines's situation where the family decided to adopt a general chastity policy, if the introduction of the belts was indeed in response to one person's misbehavior.
Furthermore, while I obviously would consider
WriterAlexis Even when she does trash her life, the consequences she faces are so much lower than what I would, because mom is closer to her.
The whole reason I had to start wearing a belt was because my dad didn't want it to seem like he was favoring me by being my biological father and making only his stepdaughter wear one. So I harbor some resentment that she gets to receive favoritism in the form of breaks and privileges that I no longer have.
this bit a case of unreliable narrator, and would assume that Alexis surely did something that caused her to lose privileges that her sister enjoys, there is clearly some work to be done in terms of ensuring fair standards. Even if there is a uniform chastity policy in place, any punishments or rewards regarding that, such as gain/loss of privileges and such, should follow a clear set of rules in such case. Everyone gets the same baseline arrangement, and all deviations from that are either uniformly shared by everyone or inflicted specifically on the person who has done the deed. Any punishable misbehavior should either be specified as such in mutually agreed-upon rules or be so egregious that any reasonable person would agree that it merits a punishment. Rewards may of course be a little more ad hoc, but the reason for a reward should be announced such that consistent standards can be monitored.
Now obviously, this has so far completely ignored the matter of consent, which to me looks like it is formally there, but neither meets the standard of freely given nor of enthusiastic. That is of course an entirely different matter, but this is about a double standard. Non-consent obviously makes this worse, but even in a fully consensual arrangement, that would be a red flag that merits a serious discussion with the possibility of revoking said consent.
