After a fairly vanilla first 12 years of our relationship (have explored prostate play amd pegging but not a lot other than that), this last few months has seen quite a bit of exploration.

Last week, I blindfolded my wife and for the first ever time had her imagining another fantasy man making love to her while I fucked her. This was a HUGE step into new territory for us.

She quickly became incredibly wet, moaned, and came faster and harder than I've ever known as she imagined another man was fucking her.

I have a few directions that I now want to take this in, but have had difficulty as we seem to have hit a wall.

My plan for tomorrow evening is to blindfold her again on the bed, and play an audio erotic POV that I have found: https://www.literotica.com/s/the-masseuse-10 The audio is of a guy pretending to be a masseuse and ending up pleasuring the listener. I will massage her, and end up fucking her as him - possibly with a dildo at first that is twice my thickness, and about 1.5x my length. After she cums on the dildo, I will ask if I can go after him (perhaps licking her first - to plant the seed of a potential clean up in future) - then see if I can get her talking about what it was like to fuck him, while I fuck her.

I can already tell that the seed is being planted to pave the way to hotwifing - whether we go cuckold, or stag/vixen/swinging (more likely).

What roleplaying has worked well for you?

Can you suggest any future sessions / directions that I can guide the role playing in?
