Yea, those would be the current scenes in the build. As mentioned, once you see hearts that's when scenes are able to be triggered meaning their lust value is high enough. Then you just get caught to see a scene. The Tobi-Kodachi has 2 variants of its scene. Enemy lust goes down after a scene so if the hearts are gone then they go back to attacking normally.there's three with the lizards (blowjob, vaginal, and DP), one with the wolfs (doggy), and at least one with the tobi-kodachi (mounting?). There was animations with the boss, but that's not in this current build.
You trigger the scenes by letting the enemies attack you when they have hearts floating around their heads, and something with lust values deciding which specific animation plays. I'm not sure Haou will have to clarify.
