What is you most extreme/socially unacceptable fantasy?

I would bet myself included that I'm not allowed to post what it would be?

Fucking someone while they are on the phone to their other half. Or fucking someone while I'm on the phone to my wife.

But it will stay a fantasy forever I love my wife too much to ever cheat

I love wearing knickers. I have several pairs of my own. My fantasy is for my OH to humiliate me in front of a couple of her female friends by telling them how I love wearing knickers and making me strip down to show them the knickers I'm wearing.
Also for her to say how I keep begging her to peg me.

I would also like to suck a cock. Me the OH and another couple talking and I end up sucking him off in front of the women.

Being tied to the bed with my head hanging off the end of the bed, blindfolded and having a guy fucking my throat when I'm expecting something from the OH.
