I can tell you where considerable amounts of dom content are and where to find them, but lot's of it is just spread out throughout the game, so listing all of it would be difficult. Most of the time, if an enemy has a victory scene, the player will be the dom, but I don't have a list of which enemies do and don't have victory scenes. It's more common early on into the game I would say, the first dungeon has a lot of it, and a decent amount of the events in there can be dom as well. Additionally, both of Alexandra's dungeon's have a full sub/dom route with her after the boss fight, so the second and fourth dungeon will both have a good amount of dom content at the end as long as you beat her/her pet minotaur. I think the fourth dungeon is mostly sub content otherwise. In the third dungeon, picking the tomboy outfit gives you some dominant options, off the top of my head I would assume there's quite a few, but I'm not 100% sure about that. You will also encounter a blonde male adventurer throughout the dungeon's, who you eventually get to make up a name for since you never ask his, and his content can go either way. He definitely has content in the second and third dungeon.
For characters, Katie is probably the most notable, as she has an entire sub/dom route. You can check the walkthrough file for what events can let you increase your dominance over her, and alongside progressing through dungeons will unlock a number of dom date scenes with her at the guild. Daisy is also generally submissive towards the player, though this flips on occasion. Beatrice is almost always dominant, but her second scene where she grows a penis has her switch to being submissive. Claire is kind of neutral, she's usually leading but she isn't super dominant, and things switch around plenty.
Overall, I would say if you are asking this because you only want to see player dominant content, it's going to be a bit tricky. Because there's a ton of scenes in total, there's a decent amount of it, but it's going to be rather spread out. I wouldn't go out of my way to recommend the game to players who just want dom stuff, but you still might enjoy it.
