Nervous but excited for what’s next

Recently my wife and I have been experimenting with chastity. I wear it to work most days and then when I come home my wife unlocks me. Yesterday while I was at work I told my wife she has full control over when I stay locked and when I’m allowed out. She got very turned on when I said that. She gets home from work before me so while I was still at work locked up she starts sending me photos and videos of her using her dildo. I immediately get hard and she tells me that she’s gonna keep me locked up for weeks. That only she is going to get to cum for now on and if I’m a good boy she’ll let me eat her ass. Then she even went as far to say she’s gonna find someone with a bigger cock and make me watch him fuck her while I’m locked up and if I’m good I can lick her after he’s done. I was so incredibly hard during all of this but also am nervous to precede. When I got home she kept me locked and made me sleep in it. Now I’m just left here wondering how long she is really going to keep me locked up and where this is going to go.
