Not really sure where I'm going, so I will start typing, and see where we end up. Perhaps I'm getting carried away, perhaps it has gone too far already.

Recently, I've been caught up in my own little bubble. Time off from work, staying up late watching porn and reading into cuckold, and not getting out very much, all seem to have compounded.

Cuckold. It's the taboo I think that drew me in. The rush of excitement, the shift in power dynamic. The shame of disgust, rejection, or humiliation if my friends find out.

What started as a fantasy when jerking off alone, slowly made it's way into our bedroom. Exploring the world of eating cum from my wife's pussy - hinting that it would turn me on to be cleaning up after another man.

We fucked recently with her on top. As I squeezed her bum, the thoughts of another man entering her from behind for a dp. In the past, the thought would have been fleeting and I would have let it slide - this time I didn't.

My cock surged as I shared this fantasy with her - cushioning the MMF fantasy by saying "another couple", when it was his dick thrusting inside her that I longed to hear make her moan.

I lubed up my fingers and entered her arse gently - whispering in her ear, "would you take another man's cock here..?"

She came on my cock that way - fantasising about being fucked by another man, her husband whispering in her ear about how hot it would be.

Read the last paragraph again. Imagine that being your wife, cumming on your cock, with you leading her through an MMF fantasy, while your finger gently teases in and out of her arse.

It's gaining momentum . Is there a point of no return?

Where will we go next with this?
