Dunno how can they be any stricter on diapers, Alice already has to wear them 24/7 :P
On the restraints - at least for Alice, they aren't mandatory at home, other than the locking clothing. Unless she does something silly
Would that be the same for Sarah, or would you like to be stricter in that regard?
On the diaper topic, maybe she could reluctantly wet hers but still try her very best to beg herself out of them and make it to the toilet, rather than messing herself. A wet diaper is still not nearly as uncomfortable and humiliating as a messy one.
I know the feeling, my own college years are still fresh in my memory. I genuinely hope for your quick recovery
You'll have to figure out IC :P
