Most taboo fantasy?

My fantasy is to be in a relationship with older chubby man,he forces me to be a slutty obedient sissy allways dressed in miniskirts&stockings&high heels,i must convince his family that i,m the one who makes him happy,but they don,t know what perverted taboo he expect i,ll do for him but i,m so in love with him i,ll do whatever he wants from me
Looking good show off some more nothing like a beautiful cock and a nice set of panties
 
Not necessarily the wildest one here but love the idea of having a bull fuck my wife while my friends are over.

We would all be downstairs watching the football, having a few beers, when the bull arrives and takes her upstairs. No explanation, just confused stares all round. Before slowly the sounds of moans and beds creaking fills the house and I just have to sit there in that humiliation.

Even better if some of my friends go up to watch/join in or the the bull just sends her back down filled with cum, acting like nothing happened.
Totally hot, especially just sitting there with your buddies on the couch and your wife coming back downstairs with cum rum, and running down the inside of her thighs you’re like hey honey let me get that for you as you wipe it off with your finger and then put it into your mouth

Exactly!

And having the bull join us afterwards would be the icing on the cake.

Anything that ramps up the humiliation is a huge turn on for me.
