Your sister will be staying at your place for university summer break. She tends to sleep a lot, maybe you could take advantage of that and have some fun together! The game is still under heavy development, there are only 8 H-Scenes so far. I'll be adding more as the development continues, as well as more interactions, different game features, sprites, CGs, and more!​

v0.10 - New interactive H-scene (unlocks after the second lewd event, simply press "Touch Chest" when interacting with Mayu)<br> - Kissing has a slightly new approach. She'll ask you to kiss her cheek once during a random chat, from there on, you'll be able to initiate kisses whenever. First on the cheek, and then on the mouth. Dialogue will progress depending on how close you are with Mayu<br> - A total of 6 new CGs: - Lewd event 5 - Lewd event 6 - Love event 4 - Replaced the last 3 CGs by C.W. v0.09 We've added 8 new CGs total. CGs for love event 1 and 2, as well as lewd event 1 were replaced. We'll be replacing the remaining SW's CGs in the next update. We've added lewd event 4, containing two brand new CGs. We've added an option to cook for Mayu, leading to the nip slip CG. After the 3rd love event, you'll have a new option available when interacting with Mayu, leading to an ear cleaning CG. And finally, I've adjusted the prologue a little, also adding a new CG. In addition, the kitchen H-scene was updated. I've redrawn parts, re-rigged, and reanimated quite a bit. Hopefully, things should look smoother now. You can also climax multiple times in this scene now. You can also completely undress Mayu now. The aspect ratio was changed to 16:9, but only the paizuri and kitchen scenes are drawn with horizontal aspect ratio in mind. I'll be updating other H-scenes as we keep developing the game, but a few of the scenes will probably remain in vertical format. Things may look a little rough on wider displays. I'll solve this issue in future updates. v0.08 •❣• New dialogue •❣• 3 new events (two lewd events and one wholesome) •❣• 3 new CGs •❣• 5 new backgrounds (drawn from scratch, replacing old royalty free ones) •❣• Bugfixes (most notably, you can now save in the web version) •❣• New H-Scene: You can now buy a lewd doujin. When you gift it to Mayu and have more than 500 lust/desire, she'll offer to read it together and then replicate a scene from it. In this scene you'll be able to: take off her arm covering her booba, touch the booba, initiate bobjob yourself, put it in her mouth or; giver her command to: initiate boobjob, boobjob + licking, boobjob + put it in her mouth. In addition, we've also done a lot of work in preparation for v0.09, but more on that later. v0.07 •❣• Implemented shop (very barebones, please don't expect much for this version) •❣• Three new original BGMs (by Colorgeist) •❣• New dialogue •❣• New sprite •❣• New Lust events (at 100 lust) •❣• New CG with a bunch of variation •❣• Fixed some bugs •❣• Added more bugs •❣• New H-Scene!: Every time you chat with Mayu, you'll get a bit of money (both shop and ways to gain currency will be worked on in future updates). You can buy Neko Bikini in the shop, gifting it to Mayu will trigger a new H-scene. Available actions: remove bikini top, remove bikini bottom, touch chest, touch butt, plap plap, finger. v0.06 •❣• Settings will now be saved •❣• Added a Hide Socials toggle in the settings •❣• Two new BGMs •❣• Added new dialogue •❣• Added a system where you can go outside with Mayu •❣• Added 2 new Love Events (at 100 and 200 Love stat) •❣• Added 2 new CG with a bunch of variation •❣• Fixed some bugs •❣• Added more bugs •❣• New H-Scene!: v0.05 ෆ Added new dialogue ෆ Added new voice lines ෆ Added save feature ෆ Added localization system (Translation: Pulse (JP), Quentin (FR), 太上月华静夜天尊 (CN), Lordscarpio (ES)) ෆ Added new BGM and SFX ෆ And countless bugfixes and smaller changes! New H-scene: ୨୧ Mayu will now occasionally go to the toilet ୨୧ You have an option to peek ୨୧ If you peek for too long, she'll catch you a tell you off ୨୧ If her lust is 20% or higher, she'll also masturbate in the toilet ୨୧ You have an option to walk in, scaring her off ୨୧ If her lust is 40% or higher, she won't get scared off and offer you to watch her ୨୧ In that scenario, you will have an option to lower her shirt and masturbate along with her v0.04 - Updated UI - Added a few more house assets - Added settings menu - The chat option will now show an "!" icon if the chat hasn't been finished before (thought even in completed chats you may notice that Mayu's behavior might change a little depending on stats) - Added a little more dialogue - Added a small interaction after Mayu taking a bath (you may notice that she's a little vulnerable if her lust stat is high). - Added voice acting! Hazuki Mana did a wonderful job giving Mayu a beautiful voice. I plan on adding more voice acting in special events, and maybe even getting the game 100% voiced if the support continues the way it has been lately~ - H-scene 04! You can touch her thigh, lift her shirt, lift her skirt, pull her panties down, lift her legs up, finger her, have vaginal and oral sex with her v0.03 N/A v0.02 N/A v0.01 Initial Release

3/5 Meh, a bit overrated when reading reviews. I like games of this type and i know this one isn't finished yet but i can already tell it didn't hit me. - art is nice but from screens i thought it will be way better, animations are very smooth but also rather simple so it gets repetive very fast - its loli girl, i prefer a bit more mature ones - seems like you get money overtime, there is nothing to do besides scene collector and waiting for events, meanwhile there is annoying animation of girl going around house super slowly that makes you click "skip" button everytime - i didn't like sex system that much, it felt a bit unpolished, also i had a bug in one of early scenes and had to restart game - and that's kind of it, not much more for now , i seen few scenes, i think 2 were locked by patreon, maybe it has potential when finished

Keep in mind please I am very, very critical of artstyle and the quality of art when reviewing games. It is the factor that weighs the most in the review. The art of this game is great, stunning even. Worth it for that alone. Currently the story is barebones and an issue that irks me. The motion of the animation is so absurdly exaggerated. Honestly it sort of takes away from the beauty of the art. Hopefully the dev can tone it down just a bit and make it more enjoyable. Overall all the game is WORTH IT.

A delightful if not simple game- As the description may imply, you are being volunteered/told to keep your sister for a while. Why? Who cares! Apparently she's narcoleptic or something? That part is never super explained well, but she sleeps in random places and is apparently so clonked out that you can do whatever you please without her ever waking up. What this game really strives for and (in my opinion) knocks out of the park is the CG scenes and the dialogue between the two siblings. Mayu is a very funny character, and I can't help but have a sweet spot for her. She's loud, obnoxious, full of herself, and sort of entitled, but she is genuinely a caring person with a lewder side, a side that is quite quickly revealed even after just a few days of living with here. I was genuinely surprised at the amount of fun I was having going through the various events and seeing how the bond between our two characters developed. To be fair, I really did not understand much of this "choose your path" type of gameplay being suggested, but then again I played while increasing both the love and desire meters fairly evenly, so who knows? Maybe your milage will differ. All I do know is that there are some surprisingly good scenes for you to interact with. My favorite is when you can take Mayu out for a stroll and then bring her behind street lamp to finger-blast her and fuck her while people pass by. This also introduced an unexpected yet welcome mini game of trying to get either her or yourself off while not trying to draw much attention. If you're moving too fast while people are near, they'll be alerted to you. I look forward to seeing how this game develops in a full 1.0 release. My only wish is for some butt stuff to be included- then this would be a 10/10 game.

I really like games like this about everyday life with my little sister The game has no plot at all and that's fine not everything needs a plot it has cute dialogues that develop your relationship with your little sister The game is very simple and you can unlock everything in a few minutes the graphics are nice plus although I liked it less [in my opinion] the interaction with your sister is good but it annoys me that the interaction doesn't continue I'll give an example: you're sleeping with your sister and you decide to cum in her mouth or vagina after you cum it goes back to the beginning as if you didn't cum I would be happy if there were 3-4-5 stages of dirt that would add something cute and give something extra to your "work" and there are two more things that I would like the developer to add the option to do two things at once for example fuck and touch because it's pretty annoying to change every time it really hurts the continuity and isn't that fun to continue and the third and last one would be automatic dialogues because it's not fun to click the mouse every time Besides I'm glad there are developers who bring such content because there is a great lack of daily games A day in a simple way that advances the player [I would complain that there are no consequences for actions but it's a fantasy game to be with your little sister] I hope the developer continues to bring new content to the game because I'm really looking forward to the next update

This is one of the best games I've found for Android thus far. Great art, cute dialogue, lighthearted lewdness... Everything is really good. Sure, it's still sort of barebones and whatnot, but hey, v0.8 thus far is quite nice. Little sister games are always a hit or miss, this one is a clear hit for me. Also, pachipoi, you're a damn legend. Posting your own game here on F95 is something I've only seen a few devs do. This alone makes me wanna buy the game once it's out. Really nice. Thanks again.

Nemurimouo - v0.07 The game has some appealing erotic scenes and interactivity, but it lacks meaningful gameplay mechanics and feels more like a barebones game framework. Good scenes + nonexistent gameplay = 3/5
NuuRaa 2024-11-06
(v0.07) simple and fun looking game, while its still short on direction and game mechanic but have a nice scene. its even has outdoor thing haha. i hope there will be thing in the future that make her mad, and game over.

Good game from what's currently available. Mayu is cutely written and there is a good variety of scenes available. It's much harder to fill the love status as opposed to the lust one, but that's generally always true with games like these. The animations themselves are quite nice and are extra impressive as they're done in 2d. Definitely a game worth watching and perhaps supporting.

Fantastic for what it is, I can't think of a mobile game that has the level of art that this game has. I will be looking forwards to future updates without a doubt, highly recommend for those with a little free time, you can -probably get all content in around an hour
Lucafirmeita 2024-09-12
Nice little game, I'll wait some time to see how it develops, for the patch (0.06) is solid base The art is cute, animated all scenes, and a gameplay that doesn't get in the way of enjoying the scenes, story is trope that we see many times, maybe something will change, I would like to be challenged in some way(like she won't let you put in without some requirement), but that's up to the developer to decide.

Oh wow this game really pulls me off even with its early build and i already came twice while playing this game and i am amazed by the CG scene and how cute the heroine is, it is one of the best game out there imo. Story: -/10 The story isn't finished yet and i can only understand that his sister came for summer break and living together and thats all so gonna update it later if the game finished Art: 10/10 For a mobile 2d game, it is one of the best among thousand of similar game out there Gameplay: 7.5/10 Gameplay is pretty simple and fun but i hope there would be other variety of mini games like card game, mini puzzle or something. Overall: 8/10 This game clearly hooked me up and once i know the game is on steam, i straightforwardly press the wishlist button. But its too bad i have to wait for at least 2 years for the game release but its worth it. Highly recommended

Even with what there is here it fucking blows the everlasting fuck out of most games and 120% of any retarded censored Japanese games. Game does not run like it's on dial up. It don't ask for a absurd amount of time to be wasted to see and do anything. Could there be more? Of course there could be. However with what there is already it shits on most mediocrity on DLsite. For me it is strongly similair to 'Hizashi No Naka No Riaru' in terms of a good looking touching game. Overall in truth being unfinished it ain't really a 5 star but alas when compared to what quite little competition this has in english.... then it's a 5. I'd actually buy this outright if it ever fully released

Straightforward game with good, high quality scenes. I've tried mobile version which feels great, especially with the automatic saving. Has some story, but it's not too much to the point where you'd feel like starting to skip it. It's just balanced. Great work, keep it up!
Cheetachaser 2024-02-04
Entertaining, a single minor error I have found which involves the toilet scene. No obvious errors in gramar or syntax, nor in spelling. Sprites move mostly smoothly, except at higher speeds, which I assume doesn't matter since I only use speed six in automode to skip things.

This game is just beginning, but it is very interesting. It has several tags that are my favorites such as sleep sex, incest, creampie; What really caught my attention was that view from the top of the house where we can ''manage'' the events and explore the house. The shop that is under development is also very interesting, I can already imagine a lot of items that we can give her as a gift (to improve our affection and relationship) sexual toys, we can also buy medicines, such as the morning-after pill (where something related to pregnancy could be developed), condoms, sleeping pills, and more; I really like the animations and the graphics, the semen has good consistency and is also very well animated I also imagine the story developing incestuously, little by little improving the relationship with her, her accepting or falling in love and also unlocking new scenes according to the progress of the story and relationship with her. (--EDIT-- I was perhaps forgetting to talk about a ''wake up'' bar, increasing the difficulty and the use of other devices such as medicines and also the intensity of the act we are doing. Another thing that I find interesting would be her corruption or something similar, the option of not leaving traces of what we are doing to her in her sleep or making it very explicit to her, until she no longer cares about being woken up with sex) I'll leave here as a reference my two favorite games of the genre Night Adventure [Final] [Frazunk] Imouto! Life ~Fantasy~ [v1.4.3] [Inusuku] I loved the game and looking forward to what comes in the next updates
HentaiGeheBoiz 2024-01-01
As it is now 0.05 version: Its quite good considered its version, it already has quite a few sex scenes and some resemblance of gameplay. Everything is animated thats a plus too. Also clothing system is intractable tho not fully implemented in some places. (In a sense of you cant modify everything) But animation quality and scenes are just not that good. She moves way too unnatural like made entirely out of water. There is no interaction its same as fucking a doll. As it is its good idea to keep eye on it awaiting what it will become.

Reviewed as of [v0.03] Game is obviously very early on in development, but it definitely shows promise. The art is nice, the dialogue and conversations are fairly cute, and the dev has set up the basics of the core game play loop. There's really not much content yet, but I like what's there so far. Should be interesting to see what it looks like after a few more updates.
