If you're into sandbox games I have some more suggestions for you.
House in Rift is a story heavy sandbox. You'll need to spend time with all the girls to progress the story but it is a good story. Very nice renders too.
Long Live the Princess is another story heavy sandbox. Excellent story, has a fair bit of sleep molestation/sex content if you're into that. Mystery/investigation type gameplay which is different, but interesting. There's a built in New Game+ mechanic, so you won't get all the scenes on your first playthrough.
The Headmaster has a weaker story imo than the games above, but still an excellent game. This game focuses more on having a large roster of girls to progress their stories, and there's a fair bit of content with each girl too. Heavily focused behaviour modification through spanking.
Rogue-Like Evolution is a great X-Men parody game. No real story to speak of, but great sex mechanics. Play the base game if you enjoy a stretched out (but rewarding) grind, play with the Prime Mod if you want to get to the sexy bits quickly.
Holiday Island is another one of my favourites. Not a lot of actual sex content yet but it's a very sexy game especially if you're into breasts on the larger side. Big focus on teasing. The girls dress sexily and you're often encouraged to check out their assets. I suggest using the Companion mod as well as
this mod that allows you to have all the girls on your island at the same time.
