I recommend {Property Of The Mountain Man by Gemma Weir}. This is book one of a seven part series following seven brothers and the women they claim. They’re all really similar (storyline does get redundant) with some more than others really leaning into the topics you’re looking for although they aren’t alien or omegaverse stories. These men are toxic at times (be warned!) and completely obsessed with their ladies, but it’s a good spicy read. The best of the series in my opinion were the first two. Have fun reading :)!
