Yes. All of these. So much. It would be more work, but even better if Kali's sister asking about anal had something to do with her first anal scene. Either that triggers it or she blushes/responds in some way if it has happened first.
Of course, the threesome scene possibilities with her sister (which, as we all know, is totally just her step-sister or something... right, Patreon?) also spring to mind. So many options... Blowjob contest after sis teases her into it by making a move on the MC? Or perhaps the dominant traits of the sister come to the fore as she forces Kali to go down on her while the MC fucks her. The "dominated by my younger sister and boyfriend" and cuckquean opportunities are pretty rich with a lot to explore.
While we're on the subject of suggestions, it would be nice if the dungeon scenes had a little bit of tweaking. First, there's no aftercare. You just have the scene and then tell them to leave. Given that the game generally has a more affectionate tone it would be not only more appropriate, but realistic to spend a little bit of time cuddling and telling them that they did a good job after the scene. Perhaps this could be an option where not giving them aftercare is what causes them to lose points of submission and/or affection.
Second is that most of the spankings/whippings feel a bit... perfunctory at the moment. You give them a number of strokes and then "OK, we're done". Ehh... This could be easily improved with a bit more writing. Let the scenes build up a bit and reach a climax. Give them a number of strokes to begin with and have them count them out loud. Use their responses to show that they're varying in intensity. There are a lot of options.
As someone in the BDSM scene it's great to see so much of the dominance/submission aspect handled so well. Usually games are just all about being cold or a total asshole, but this shows more realistic dominance with actual care and affection.
It's mainly the dungeon scenes that could use some help. Almost all of them are just orgasm denial, but with the submission restriction making it feel like the game is truly in control. Like with Lin, I wish I could leave them edged and horny. I think it would make more sense for the submission stat to decline only if they stay horny for too long. Then they lose a point of submission, masturbate (which you can watch, like Lin), and reset back to 0 Lust.
It's also tough that most of the activities are screened off as "punishment". It would be great if we could pick what sort of activity we want to do and maybe even vary them up, e.g. edging, then some spanking, back to edging, make her clean the floor with her tongue, then aftercare with her leaving without having an orgasm.
