Ya, biggest issue with the XXX content is lack of narrative integration, IMO, and the scenes need to be significantly longer as well.
Something I've considered a bit when thinking about how they could tweak the system is that if they want to make it to where they have teaser / intro, standard / premium, and then an after scene potentially with a given girl (so that the player can customize and build their scene the way they want with those types of selections), what they might consider doing is adding a "lead-in" (desperately needed), "transition" (also desperately needed for immersion and avoiding scene-breaking), and "lead-out" (not as important, but could add to immersion) animation for scenes, some of which could be re-usable to save dev time, that would effectively begin the scene, and then transition smoothly between each section of the scene and this would take care of one of the most common complaints with Pandora that I've seen, which is the aforementioned lack of the scenes being integrated into the story.
An example would be this - let's say you're building a Lily scene...for a teaser let's imagine the devs fulfill a common request on the Steam forums and put a stripper pole in the captain's cabin and you choose that for your 'teaser' (I'd imagine eventually they'll have customizable outfits as well so you can pick what you want her to wear), then for the standard part of the scene, you select some vanilla sex scene like the premium recruitment scene in the base game, then for the after you have the cuddling in bed scene that was in the base game with Killision....
What the devs really need to do is add a lead-in that the player doesn't necessarily pick, it's just there to add proper initialization of the interaction and set the stage - with porn content, the anticipation and stage-setting is just as important to many people as watching the actual act take place - I personally enjoy watching the girl gradually get undressed sexily beforehand during foreplay - I don't want to go straight to naked or to intercourse, I like it gradual as it builds excitement. So as an example in this scenario, maybe you have the captain in his cabin doing whatever - having a drink, going over star charts, on the communicator with somebody, whatever, and the door beeps and he tells the person to come in - it's Lily just wearing high heels and a robe over whatever the player dressed her in and she just asks if he wanted some company and after he says yes, she lets the robe slide off and walks over to the stripper pole and then the actual scene commences, and then after she does the teaser dance, there's a transition animation (like I said, it could potentially be re-used depending on location, movements, and scene design compatibility, etc.) that has the waifu then walk from the stripper pole / teaser scene ending point to the bed to then begin the standard scene and continuing on to the end where they're just laying in bed together, or maybe have a fade out / time skip to the morning showing them getting up from bed together before heading out.
They could also then insert flags into the dialogue that if the player had a given scene with Lily, the next time they talk to Lily, they could have Lily, prior to any main cutscenes, have a brief commentary about how she enjoyed the night before with him, or enjoyed dancing for him, etc., again to add immersion to the world and make it feel more real.
Ultimately that's one of the biggest issues with the scenes right now - there's almost no narrative integration which significantly detracts from the quality of the adult content, and because right now it's just GIFs tied together with time skips between the sections of the scene, there's no proper transition between beginning, middle, and end so it doesn't feel even remotely immersive since it doesn't really flow realistically.
Sorry for the length, just thinking out loud into my keyboard - it's easy for all of us to criticize someone else's work, so sometimes I do sit and think about how a developer could fix a common complaint about a game, etc. that would make me happy enough to consider getting my wallet out for that product.
