There are a few I can think of:People, what are the most erotic ideas you can think of for the game? What erotic scenarios would be your favorites?
Condom play - Asuna wearing a few under her clothing after a session with Inoda and going on a date with Kuckito. Something I've seen a few times, but always think hot is dropping a ring into a filled condom.
Similar idea - Having a conversation at a coffee shop or in the office, complaining about it not having enough cream, walking off to Inoda, and then coming back with her special coffee blend.
Naked Apron play in the apartment. Or in Asuna's house. She goes home, finds Inoda waiting for her, cooks naked and eats with him in just an apron, blowing off a date with Kuckito.
Shower sex - which we haven't had yet in this game I don't think. We've had some shower scenes, but not sex. Inoda using his powers in the game, or just sneaking into Kuckito's apartment while Kuckito is doing homework and Asuna is showering for some reason.
Another thing we haven't seen yet - beach stuff. Just Inoda and Asuna going off alone or on a full trip by themselves.
Similar idea: in game moments where they have to go underwater, Asuna and Inoda having fun behind Kuckito's back.
Church play in the game - we've seen some hints of this, but having Inoda fucking Asuna on the other side of the confessional or blowing him through the confessional wall.
In the game, near to the end of the game: During a fight, Kuckito need's Asuna's backup. She and Inoda have been fooling around in the background for a while, but now Inoda stops just as Asuna's about to cum, demands Asuna choose helping Kuckito or having more fun. A choice for the player.
