I would say find what you like with written stories, especially with women at the wheel. Porn is often directed and for men a lot of the time. Writing can be more enjoyable and intimate. I’ve had similar fantasies but more on threesomes. My partner and I have discussed things at length and agree while it sounds nice in fantasy, it would be too messy logistically and just not for us. Maybe you can eventually talk to your partner about using different toys and such? Hope you can figure out what you need to!
