It's just a taste--and that's fine, hopefully there will be a lot more in the next update. I'm assuming this is an alternate universe where Naruto, Sasuke, and others that the LIs would normally be with never existed. At least I hope that's the case. I absolutely don't mind cucking characters, even characters I'm fond of (I'm not actually fond of Naruto or especially not Sasuke, but if this had been a parody of something with male characters that I actually like and respect, and their significant others or potential significant others were potential LIs for the MC, I wouldn't mind cucking those characters.) However, I'm kinda of done with stories where Sakura/Sasuke or Naruto/Hinata are already an item, would much prefer more stories where it's right before that might have happened. And I'm actually really starting to get tired of stories where they got killed or kidnapped, so maybe it's better if for some stories it's an alternate universe where they never existed at all. But we'll just have to see what actually happens.
Anyway, if the guys did exist, I would expect at least 0.03 seconds of hesitation. The way Sakura acts in this VN would just really be off. But on the other hand I actually really love the complete lack of hesitation and shame, hence why maybe it's better if the guys didn't exist in my opinion. Even if you, the MC, are a sex god superior to Sasuke in every way, I think there would be at least a moment of hesitation. But in an alternate universe where there was never a Sasuke to begin with, and suddenly she meets this mega chad, the MC fills in that role immediately and I think it would be the same for Hinata if Naruto never existed.
I like Sakura's lack of shame, lack of hesitance, immediate willingness to get with this complete stranger who she just can't resist. I also like her proactiveness. And I definitely like what she tries at night--as a possibility. I think it would be nice if the MC got the opportunity to make the first move. Keep the night scene, but maybe add an option right after they meet where you can make a move on Sakura right then and there. Personally I'm a fan of doggystyle positions though you could have a poll on what position the added scene was in (if you were inclined to add such a choice and such a scene at all, that is.)
I also think that the doggystyle portion of the night time scene could have used some animation like you get with the BJ. It feels like the whole sex scene just got skipped. Don't know if that was just because this is the very first version of the VN.
Can't wait to see Hinata added, she's basically why I click on Naruto content in the first place. I don't want to criticize a completely different game in a thread completely unrelated to it--especially since I like the game in question--but there's another Naruto game where a lot of the LIs who had men before the men were zapped away to another plane of existence (probably not dead,) are pretty resistant to getting sexually close with the MC out of guilt, to the point of blue balls and frustration, but Hinata really takes the cake in this case.
I actually prefer longer-hair, bigger-boobed, not-quite-with-Naruto-Yet Hinata to the Boruto series Hinata, the Hinata Naruto accidentally spied on showering in a waterfall in Shippudden, as opposed to beginning-of-the-original-series Hinata or Boruto-series Hinata. Anyway I liked the version of Hinata that's on the main menu screen. So I'm excited about that.
