youdontknowme I assume that would only work out if the two are close enough in shape and size that the adjustment range of the belt would allow for something that is at least close enough to fitting the daughter. 13 sounds like it might be a bit early for that as well, unless we are talking about the one-size-fits-all belts from far eastern manufacturers.
i agree with you and i was not thinking of an extremely long test period, maybe a few evenings where the family is together anyway for a few hours, i also did not mean a serious attempt at chastity, but only so that the daughter knows how it feels. everything else can be clarified afterwards if necessary.

i'm neither for nor against it. i'm more against buying her her own belt (maybe in a year or two if she still wants it), but she can try out mum's belt for a few hours just to know how it feels, so that her curiosity is satisfied.
