Wife has bought a strap-on dildo; I am concerned

Last night my KH wife gave me shocking news. She mentioned she has grown rather bored with her same old junk over the past 25 years and now craves a change. Consequently, she placed an order for a strap-on dildo on ebay. The delivery is expected in 15-20 days, and she can’t wait to take that solid 7-inch long dildo inside herself. OMG! What about me? Will she ever release me again as she used to do for sex? Once she gets the hang of the pleasure provided by a dildo, I worry she won’t let me in anymore, never. I just pictured her strapping on that dildo while wearing my cage, giving herself the pleasure of PIV! I am feeling worried and a bit nervous.
