It seems that there are many instances for a sub where things are never talked about specifically but they happen at some point.
For example, Mistress has never talked about or referenced actually reducing the size of my chastity devices but it HAS quite simply happened, slowly but surely and covertly over a fairly long period of time.
By default, I evidence my state of servitude to confirm that I am wearing the requested lingerie or, historically, that I am also locked in the device instructed and plugged as required. On occasion though, I have told Mistress about certain situations and said that I could evidence if required.
This is usually a rhetorical question and the answer is usually that She wants me to show Her the photos. Last year, I was on a web cam in a red lace basque and matching thong locked in my old metal cage and had become aroused at the nature of the conversation with a random viewer -- well, aroused as much as space would allow -- and casually took a photo. It was this photo that was evidenced to Mistress.
I don't remember Her saying anything by reply but feel sure that She made a note of what I know in retrospect was my ill discipline. Within a few weeks, the devices I had been put into were all smaller and shorter resin holy trainer devices with absolutely no room for expansion. Then, when I happened to come across and purchase two new (completely different from one another) devices on line, I told Mistress about them and evidenced pics of me trying them both on. Mistress very quickly very much liked the very small, very short white device called The Hive from The House Of Chastity and said that She wanted me to ensure that this was the only device I was locked in going forward.
All of my other devices were subsequently consigned to storage. Nothing ever needed to be said about any of it. My rightful place as a sub was quite simply confirmed purely by my actions alone.
The fact is that have acknowledged what has happened via the content of my social media posts and Mistress has subsequently acknowledged this through Her subtle 'likes' of these posts.
To sum up, some things don't need to be said. It is just what is required of a sub and for the sub to simply and quietly acknowledge, accept and adhere to.
The same goes for my sexual development at the hands of my mentor whilst at the salon. At a recent appointment, I was required, perhaps already pre-empted, to service him.
Fully clothed, he began using his naked sub, playing with my cock in a bid to stimulate it to an erection, feeling me up and playing with my nipples. I began rubbing his hardening crotch through his jeans but he veered away from the seemingly more regular expectation for his sub to undo his trousers by telling me he had been looking forward to the appointment and undid them himself before sliding his undies down. I stood there vulnerably for a few minutes watching him as he used my body and as I continued handling his hard shaft before my yearning to have his cock in my mouth became too much.
I then dropped to my knees and began my work, a gentle tease, a loose suck, a kiss, a nuzzle, a fondle, balls cupped and played with, a spare hand reaching around to grab a smooth bum cheek before the lure of sucking became too much and I began gorging on him, as the cock slut flame erupted, with every possible method and tactic being employed.
The more I sucked, the more insatiable and desperate for cock I became and muttered something along those lines. He asked me if I wanted to get up from my kneeling position to continue servicing him but I determinedly told him that I knew my place at the feet of cock.
