prostate massager

this morning wifey inserted my battery operated prostate massager in my ass and used gaffer tape to secure it in place.
she put 2 duracell batteries in the massager turned it on to the top speed and taped up the controller so that i cant tamper with it or turn it off.
I have to wear the massager, vibrating against my prostate until the batteries run out, i am wearing a cb3000 and black panties, so that she can see if i can produce my milk whilst locked in chastity, and the black panties will show whether and how much milk i have produced. It's a little intense when sat down but that is of no concern to her. I've not looked yet but i'm sure i have some precum milk already.
She is so inventive, but would like any more ideas from the forum.
