I quite liked this. It's short, but long enough to be worth playing. Every sex scene is animated, and they're good animations with sound effects. I esp. like that handjob animation as you don't see that perspective much (pov).
The story is okay, nothing special but not awful. I think there's a lot of potential with it though if the Dev's are interested in building on it. Things I noticed:
-The scenes all jump to the animation, before the dialog gets there. This feels incongruent, it would be best if you did a few renders before the actual animation of the characters moving about or getting into position.
-The choices mostly don't matter atm. Maybe you could do a cuck route where she tells her husband (one of the choices that doesnt work) and then branch into him accepting it or breaking up with her.
-You can add different endings, like one where she gets pregnant, either she reveals it's other guys baby or she passes it off as her husbands.
