Still on my same build, I've seen some threads while looking for tips that Reverse Cowgirl is underutilized, but they may be old posts. My suggestion would be a Seduce move that, if the enemy uses Present, allows them to shift into Reverse Cowgirl. Something similar to Hit the Deck, it puts you instantly into the position that can then let you, or the enemy, initiate reverse cowgirl. Same with stuff like getting the Handy position. I'm still playing though, so it might be there's a way to get that more often I've not discovered. My suggestion would be an alternative of Rub where your character use their charisma to do something to allure their enemy to get their mouth fucked. or to arrouse them to stroke you off, similar to pucker lips. Playing more of the game it feels like you ought to be able to Reverse Cowgirl if you have the advantage on a prone grapple that has the enemy on top of you. Maybe a move that makes them present during their grapple?
I also wanted to give my voice that I am glad for all of the effort put into these options for top/dominant builds. especially as it has cons and downsides alongside the upsides and advantages.
I'm mostly hoping Seduce becomes more versatile as a stance for engaging an opponent that's actively erroused for domination (like when they're staying on their knees raising lust.)
