So I played through the demo and I have to admit that I really liked the game. The scenario is interesting, the girl has an arrogant, yet also sweet and naive vibe to her and she looks stunning.
I also like that you've said how the husband won't find about this (so it's not directly humiliating to him) and that there's not going to be any beastiality.
But I do have a few comments/suggestions I would like to share:
- I'm willing to accept a lot in fiction and games, things don't have to be super realistic at all. However, there where 3 moments that the game went a little too far in it's creativity.
0.5) this is minor, but I would really like to Steve to get a bit more out off Sarah sharing her sexy jogging outfit. Maybe a squeeze or a quick flash, just so we don't feel too bad for him and to emphasize the loving relationship that they are in.
1) the last jogging outfit. This was commented on before I think, and have to agree that this is just a little too unbelievable. Not only because there's only 1 jogging outfit in the entire store + town, but also because she goes right back to the same store to get a new outfit knowing that the other outfit was the last one remaining.
It's also not needed. You need a reason for Sarah too wear the skimpy outfit, so why not have her trust the store owner? Surely he's a great guy, and the fact that he suggested that this is the best/most popular/professional/not at all slutty looking outfit he has made her buy it. After all, Sarah trusts his judgement enough that after 1 jog with her skimpy outfit she goes right back to him, trusting that the store owner will profit her with a better outfit this time.
2) the hobbo shooting his cum across 3 meters. Not only does this have to a world record, there where 2 things that bothered me about this. One, you don't normally have a private conversation from this distance, especially when your being blackmailed and double-especially when you have to show him your tits. I know he's a hobbo, so you won't stand too close, but 3 meters is a pretty far. Second, she doesn't notice him shooting his load against her tits. Think about it, the further you stand away from someone, the harder it is too overlook him shooting a load of cum against your torso. Just picture it.

But for real, if she was standing close to him, it's understandable she might avoid looking down to not see him jerk off. But from 3 meters it's pretty hard to not notice, especially when he's have an orgasm big enough to shoot his load across 3 meters!
Again, it's not really needed to get this creative. Having a scene where a homeless person blackmails Sarah, jerks off to her topless and 'accidentally' cums on her tits is hot enough. No need to break the laws of physics.
3) the naked neighbour next door. I am in my 20's and good god would I like to have a body like that old pervert! Simply put, he's a bit too lean/muscular. A suggestion would be to put him in a bathrobe. That also makes it possible for Sarah to get closer to him before noticing his erect cock sticking out from his clothes. You could have the old man sit in his chair, she approaches him and at the last moment noticing him jerking off.
Speaking of suggestions, I couldn't help but let my mind wander about this fascinating situation and came up with a few:
- Change the birdpoop excuse to something else (or just drop it entirely) and let Sarah give her husband a kiss before taking a shower. That way he can smell the cum and comment on it, making Sarah blush even more trying to find an excuse. I guess you can do this while keeping the birdpoop excuse, it's just that I prefer 0 references to poop in games
- When Sarah notices he cumstained top, show a picture from her pov, looking down at her top while she comments on it.
- Sarah feels so bad towards Steve for doing these dirty things that she compensates towards him. Meaning that she will do/allow things that before where off limits. You can start off that she allows Steve to buy a new tv or computer, and then later up things by allowing him to do anal/deep throat etc. Just because she feels guilty and loves him so much etc. This way we don't feel too bad for Steve and puts Sarah further in a world filled with sex.
Look post, but again I have to say that I really liked this game and hope you will continue expanding and improving things!
