As much as there are performative heteronormative expectations when it comes to the FMM threesome, i.e. it’s perfectly upstanding, straight and good as long as penii don’t touch…

…it’s not something I’ve ever understood. But this makes me think about the mechanics of what porn instructs is the most common bodily configuration for two penis-havers engageing with a vagina-haver.

Like the owner of the lower cock is mostly passive. (If you’ve ever seen these scenes, it’s nearly impossible to get a workable rhythm going and the movement of the person in the middle is only really compatible with the person who is able to thrust and retract.

Second–while any sort of consensual sexual sensitivity is good in my book–there’s a way in which this configuration almost certainly amplifies the sensation of the person in the middle. Two of three orifices are full and there is skin to skin contact in both directions. That alone would be an emotional and intense feeling for me–even before you got down to whether it was pleasurable.

Then there’s also the way that in the heteronormative world there’s this proscription against penii touch. (For that reason I’m always interested in depictions of vaginal double penetration.)

But the rear wall of the vagina and the back wall of the anal cavity are not actually that thick, so there’s almost certainly a way that although penii aren’t touching they are engaged in conversation through a screen–like a supplicant confession to priest.

If any one of the the three orgasms, the body cavity they are inside would server as a resonating chamber of sorts.

And I think that’s why I end up looking at a lot of group sex porn–it’s not the fantasy of the explicit exchange that entices me, it’s the ease with which this sort of thing is depicted in pornography and the fact that that ease of trust and intimacy is nothing something I’ve ever known (or, unfortunately, am ever likely to know).
