My wife and I had sex a few days before the new year, and then on new years day or so I was using our toys on her and started saying she should be black cock only all year and she said she wanted to do it... So far I have not put my penis in her, and she has only taken out BBC dildos. (only BBC she's ever had unfortunately)
We've successfully passed our anniversary and valentines day which my wife said felt like a big hurdle her not taking my penis on those special days but she also said it was easier then she thought it would be.
We have both been getting even more obsessed with BBC then normal and are now growing a BNWO kink. I feel like it's so wild we have gone this far already but we basically promise each other regularly we will go all of 2023 like this.
We'll see if we can stay committed enough though.
