Having always been a one man kind of woman. As things developed with my nephew, I started feeling weird about my cuck touching me, or seeing me in any state of undress because I felt like that privilege should only belong to my man who I belong to - the man who owns me. So each time my cuck either warmed me up, or cleaned me out after, or even saw me in lingerie let alone nude, I started feeling like it was almost morally wrong, and like I was cheating on my nephew. Even if my nephew was right there next to me. So in mentioning this to my nephew whilst we cuddled in bed one night that I was feeling this way, he decided that the best way to solve it was for the cuck to go fully pussy free. He was never a fan of sharing his women anyways, and it wasn't that difficult given the cuck had already been caged for almost a year by that point anyways.
In the 2ish years since, other than for his birthday present where he's fed a stream of creampies and/or piss from my holes all day long provided he's been well behaved throughout the year. The cuck is not allowed any physical or visual contact with me that could be construed as sexual/romantic in any way. If he does, then it's now my responsibility to punish him, and then my nephew punishes me as well for allowing a cuck to see/touch his property. Since the cuck is no longer allowed to actively participate, what we had done instead was have a vent that can only be closed from our side built into the shared wall between our master and the store room/nursery where the cuck sleeps so he can at least listen in when ever we fuck or make love and be involved that way.
