Angelina @Christine had to wear the belt 24/7, I think that explains the position of her mother
Might be. But it might also be that denying her self pleasure was meant as punishment for whatever her mother thought she did wrong. We just don't know.
But if you are right and complete chastity without breaks for masturbation really reflects @Christine 's mothers values, then as a keyholder Christine should actually enforce these values instead of taking the more relaxed approach she has taken so far. After all, the belt in this case should actually help her mother live up to her own standards and not just to what Chrstine thinks is right.b
