Oddly enough, I was just going to throw in 2 or so ideas for future content.
The second idea was furthering the neighbor story some. Basically, the neighbor has a minor incident (mild heart attack, fell and injured his back, something that makes him have to take it easy). The family visits him in the hospital (there is one that is unused on the map I think) and May ends up being the person that will go over and help straighten out his home. On the first or second visit, she finds the photos of her on the balcony without the neighbor knowing and is embarrassed to go back. Once she is corrupt enough, May confides to Sis what May found, sis takes her out to the balcony where they put on a show for the neighbor (without the neighbor knowing why) and May feels confident enough to go back and help. Soon, she is flashing her panties at the neighbor like she does in the store. Plus, there could be a French Maid outfit to add (buy at the store or get during a photo shoot) to the tease or have May help during bath time or wherever the story moves you. The neighbor being a voyeur is not driving this too much other than maybe asking her to clean places that make her bend over or show her panties and of she isn't corrupt enough, she refuses to do so then.
I propose softer entering sequence. No real accident, that's too harsh. Just our good pal neighbor plays some trick on May: he musters up all his acting skills and stages a show of sudden bad health. Then he immediately makes it seem like May is somehow guilty and responsible. For example, he could lure her in confrontational talk, provoke her to say something what might be the cause. This should be lighthearted, without any hard feelings, just like all other game events.
Anyway, May agrees to helps old man. She helps him to stand up, then helps him to get into his house, then to sit in wheelchair. And then begins her helping session. Which basically stems up to Submission training. Old voyeur is master of Domination! Hehehe. He orders her and pressures her to submit and do what he said. All this camouflaged in form of old man struck by sickness asking help from young lass, but he gets to her through it.
He orders her to bring him water, to bring him medicines, to help him apply them, to help him with measuring temperature/blood pressure/whatever… Any other med-related actions. While doing this, he plays dom/sub with her, gradually training her. Of course he remembers to embarrass her, to peek on her, to make his favorite photos… and he remembers to arouse her. After all, he knows her true nature: he have seen it himself on that balcony.
He can order her to wear nurse cosplay outfit when nursing him. And after that, he says that housekeeping was already hard for him, but now it is impossible without help. So he orders her to wear maid fetish outfit and do some maid work. He even can say from very start, that he is angry with her, and for his frail health he must vent this feelings by punishing her. She agrees to receive punishment and he spanks her. After that it becomes sort of custom between them, she receives many more spankings.
After one demanded session (or two, or three), old man proposes to May make it her regular job. He even can pay her a little, but main hook for her in it is her guilty conscience and wish to fell herself good and moral. And arousal from submission, embarrassment and all ecchi stuff he made her endure, but that she won't admit. So, she agrees to that. And this is how she starts new complex relationship, which will give us many fun scenes.
Further development here can lead to anything, sky is the limit. When I ask my imagination about where this can lead, it shows me scene in park or whatever public place. May dressed as maid brought old man in wheelchair here. She does not wear panties by old man's orders. He tricks her into arousal then provokes her to jump to angry sex with some passerby. Old voyeur could even lure some passerby for this. By flipping her skirt, for example.
In short, I believe in that old neighbor. He has great potential, I am sure.
