I didn’t know what I was going to write for today’s Masturbation Monday and was pretty much all out of inspiration. I usually ignore the photo prompts and just write what I want. This week, though, I clicked over to the page to see what the image prompt was, and… well, look at it! My mind started to spin, and this is what it came up with…

I try not to squirm too much in my seat. She hates when I do that – she interprets it as complaining, which I’m not allowed to do. Across the table from me, my Mistress calmly eats her salad, occasionally looking up from her plate to flash me that devilish smile. Her strawberry-blonde curls tumble to half way down her back and her breasts look fucking incredible in that black dress she knows I love and, undoubtedly, her favourite push-up bra beneath it. Her fifties have been kind to her – in the thirty years I’ve known her, she’s got more beautiful with every passing year.

As for me, I’m wearing my best suit – it is our anniversary, after all, and this restaurant is very expensive. I’m sure to anyone observing we just look like a normal, middle-aged couple out for a special dinner. What no-one else knows is that under my trousers, I’ve got a glass butt-plug nestled deep in my ass.

She bent me over our bed before we left, lubed up the plug and slid it into my ass, telling me that I was going to be a good boy and wear it for her all night – without giving the game away in public, of course. And so here I am, feeling it inside me with every movement and trying not to let my face betray our secret.

She pops a forkful of food into her mouth and her eyes lock with mine. Her eyes smoulder with lust and I just know she’s wet and not wearing knickers under that dress. Tormenting me is her biggest turn-on. My cock twitches, unable to get hard in its prison but straining at the metal walls nonetheless. My ass tightens around the hard glass of the plug, sending a rush of pleasure through me.

She swallows her mouthful and mouths a single word at me. Her favourite word. “Mine“.

I am hers, every inch of me from the greying hairs on my head to my plugged ass to my caged cock. I only hope she will let me eat her beautiful cunt when we get home, while I get no pleasure at all.
