Allow me to present the Patrician's Choice. By which I mean, my choice. This is my choice.
See, the first woman, the longstanding partner, she's the subquean. Pretty (2nd)girl shows up, she insists "just do it, I'd rather know about it than worry you'll sleep with her behind my back" and it becomes a whole thing from there. Beautiful!
Then the third girl shows up. And this is where it gets hot, because girl 2 starts just running the harem at this point, my input is pretty much irrelevant outside of my tastes in women, girl 2 is running around setting up dates and stuff and I'm busy not complaining.
So girl 2 is the domquean and the one who's just like "fuck my boyfriend BETTER, I know I taught you he likes his balls sucked" and meanwhile girl 1 is the one I never forget about who is constantly turned on by the idea that I might forget about her, until after a threesome with two other women when I call her over from where she's masturbating by the door so that she can join the cuddlepuddle.
I like to imagine the dommy girl coming out of some middle management position and just taking that persona straight to the bedroom and kitchen where she attempts to dictate everything and then all resistance just melts the moment I interrupt her plans with one of my own. "Oh... Guess I'll just reschedule the whole week then because you wanted to do something else...".
Harem anime are my template for modern relationships. Fuck everyone else.
