As far as I'm aware, (for those who care at this point) the next update will have Haruka and Kayane for sure. I've looked around and read that it's the strip club, Honeybee contest, Onsen and the Motoko dinner.
My guess on the girls featured are; Haruka (confirmed), Kayane (confirmed), Motoko, (confirmed/probably Yukiko as well?) Sheila (confirmed), Minami (gross/confirmed).
Sex scenes that are probably going to happen at a certain time;
1 Haruka and Sheila at the Honeybee contest, probably a choice here? Winner fucks MC? idk
2 Kayane at the club
3 Motoko at the mansion with Yukiko probably?
4 Tomoe (somewhere in here?)
5 Minami is getting a new status but who knows what that means (maybe a scene here?)
Will probably see other characters in the update but without lewd scenes
(ALSO COULD BE MORE SCENES WITH THE HELP OF FROM HIS HELPERS? IDK (OR WE GET OPTIONS THAT AREN'T PLACEHOLDERS FOR ONCE)
ALSO hopefully Minami doesnt get anymore scenes for a while, she already has like 6!! Jesus christ, give KAORI a dickening lmao.
