Chastity and orgasm denial discussion

My Wife put this to me tonight. She was heading out for netball and I asked if I could wank while she was away, hoping she’d say no; instead, she pretended not to know where the keys were. She has been very good at denying me lately being very strict and refusing me release, but I know she finds it awkward and we have never had sex with orgasm denial. Last night she unlocked me for a wash and I walked in the bedroom as she was hiding the key, she obviously stashed it quickly and forgot to hide it properly later on, I found it straight away just now. Maybe she couldn’t remember where she stashed it. Dilema… I initially intended to throw the key in the bin!! Drastic I know but then it would kind of force us in to longer denial and hopefully orgasms for her with no release for me. I’ve decided to leave it where it is and say nothing, and see what she does. Hopefully this will be a good ‘excuse’ for her to accept some orgasms without feeling the need to reciprocate
