A couple of things about Kira threw me for a loop. I believe her Kissing lessons are required to advance both Lisa and Alice's quests, but Kira also has a separate event where you just watch porn together that happens at the same time as the kissing event which is required for her quest line. You have to do both options but you can't do them both on the same day.I checked your save file
This happens because you haven't completed the night events with Kira and the "favorite aunt" opportunity yet, and you haven't progressed as much as you need. Please get the game guide from the first post. And read the parts "Events of Kira" and "Favorite Aunt" and act accordingly.
If you still have problems after doing them as needed, ask, we will help you.
So if you always kiss her then you'll never do the photo shoot with her for instance. If you always pick the porn option then you get the photo shoot option with Kira but you'll be stuck with Lisa and Alice forever. I had always picked the kissing option in my latest game and couldn't figure out why the photoshoot event just refused to trigger. I had actually already been getting blowjobs from Alice long before I ever got the photo shoot with Kira.
