Kaja As usual Kaja, I would disagree with you. Monica is trying to prevent her daughter from defiling her self, and bringing shame upon both of them, she has already done plenty of that. I do think that this chastity belts can be an important part of preventing sexual shenanigans and the unwanted after effects. Unfortunately in this case the genie was already out of the bottle, so to speak, so it would be harder to get Jane to agree to wear one.
What I encouraged Monica to do was have have rational discussions about the value of wearing it, provide incentives for doing so, and stick to a plan that works for both of them. Unfortunately their deal has come off the tracks. I hope they can figure something out.
