(still open to suggestions btw).
my suggestions:
more scenes with the girls spreading pussy lips; (maybe May voluntarily spreads for someone to see? as she didn't do it yet as far as I remember)
some upskirt scenes, either with people seeing it or not;
She could reveal herself to the couple having sex at night while streaking and masturbate while they watch;
more scenes with dad/mom;
something cum related involving May; (BaoBao can have some part in this, as the person who likes to drink bodily fluids in the restaurant asks for both of their juices combined? something like that)
maybe show what happened in the halloween party with Abby (as a flashback or something);
more scenes with Betty (put her in the upskirt/spreading list too);
Maybe there can be some wind-things that make May upskirt with our without panties in some places of the town/city;
if May is a Daring Girl, we can ask to see the wiener of the wiener guy?
Maybe Lupi can have some appearance in the city in the late night (now that I'm thinking about it, a scene where she has to spread to Lupi because she has just peed outside while streaking, and somehow she gets sperm all over her because of it would be nice)
More variations of the masturbation mini game? (Insertions?)
More scenes with Earlette, maybe she can appear in the streaking scenes? Don't know if it's in the plans to make her appear outside the City
Just brainstorming some things i'd love to see on the game, feel free to veto any of these ideas hahaha
I tried thinking about assets/scenes already in the game to make it easier
