Potential keyholder

I recently brought a chastity cage and have been wearing it for a few days. I’m 24 and getting super comfortable wearing it but I can’t help but keep wanting to unlock myself.

I’m currently single so my key can’t be given to a partner and I don’t particularly want to pay a professional to hold my key. Would it be strange if I asked my step mom to hold my key to the cage?

My step mom is the only person I would trust to look after my key, since it’s just us 2 at home so I think I think I’d enjoy her teasing me a little too, is it strange I want to change our dynamic…
