Unity - Spending a Month with My Sister [v.2024.05] [Yakumo milk]

Like everyone says, the translation is quite bad and laughable. However, it's enough to get by honestly and if you don't really care about the plot, you'll be fine. The game is quite a grind as you won't get any lewd scenes till day 20ish. I enjoyed the animations and there are a decent amount of lewd activities you can do.

If you want a similar game, check out Sister! Seikatus -Fantasy-

Edit: Gave the game another star as the game is getting monthly updates and the translation is more or less fixed with mods.

I feel like the dev is cashing in on a popular H game genre at the moment rather than actually having a driving passion behind this sort of scenario/style of game.

There is really nothing special about this one, except nice animation and art. I feel like I wasted my time by spending 3 hours playing this through start to finish. You pretty much just go through a normal daytime routine and then suddenly once a quota is filled you can just get a blowjob/have sex. There is no real lewd build up (I've read through the entirety of the dialogue in my playthrough) no cut-ins or CG to show brother sister hijinks. There's not much to show their relationship building at all if I'm honest. Only numbers and one off (non-lewd, only dialogue) events once you hit a quota.

There are Practically no ecchi moments in the game either other than having a bath with your sister. You're basically either not having sex and doing chores or you are having sex, that's about as in depth as the game gets with arousal. To put it simply there is so much wasted potential here... It's a shame really.

In short, If you enjoy other sister cohabitation games this one is lacking in comparison. The majority of the game play feels detached from the actual porn side of the game as though the game play only exists to impede your journey toward sexual scenes, which are mostly just penetration at this point anyway.

Really great art and animation, but If you don't speak Japanese I recommend not playing this game. Half of it is translated, and the other half is not. The parts that are translated are butchered to all hell, and it's almost impossible to understand and follow the conversations. Even some of the choices are confusing to read.
I'm sure you can figure everything out once given enough time playing, but ultimately it's not worth the hassle. There isn't an INSANE amount of content here.
If you can speak Japanese, then great; this'll be a nice game for you. For the rest of us though, not worth the time...
