18+ Health‑Check Simulation (NSFW)
🔞 Adults Only (18+) | All characters are 18 years or older
🩷 Let’s examine our patient—Nana Tanaka!
Profile
* Name : Nana Tanaka
* Height : 156 cm
* Bust : Secret ❤️
Nana is a pure, studious honor student whose full, mature bust strains her uniform buttons. Romance isn’t on her mind, yet she harbors a hidden curiosity about all things lewd—blissfully unaware that her innocent gestures entrance every boy around her.
During P.E. her freely bouncing breasts seize the gaze of every classmate. Kind‑hearted and accommodating, she can’t refuse requests and often finds herself in embarrassingly compromising situations…

About This Game
A thrillingly embarrassing “health‑check” simulation!
As the examining doctor, you’ll perform an ever‑more intimate “examination”—probing nipples, clitoris, and more. Watch Nana’s expressions melt from flustered shame into guilty pleasure as you test each sensitive spot.

Game Features
🔹 1. Pre‑Exam Questionnaire
Review Nana’s signed medical form—complete with nipple/clitoral sensitivity tests and internal exams. Enter your own name as the doctor for deeper immersion.
🔹 2. Breast Examination
Under the guise of a stethoscope check, prod her nipples, measure her chest, and study every blush that spreads across her face.
🔹 3. Pelvic Examination
For “reproductive health,” inspect her vagina, buttocks, and anus. Enjoy her quivering reactions as pleasure overtakes embarrassment.
🔹 4. Internal Examination
With a speculum‑like instrument, explore the depths of Nana’s delicate insides. Each insertion alters her voice and expression… until the exam reaches its inevitable climax inside her.
Using a special instrument, you will carefully inspect the depths of Nana’s delicate insides. With each insertion, her expressions and reactions change, filled with embarrassment and confusion. Eventually, the exam will reach its climax inside her…

No android
No Android version????
Why is there no Android version?
The full version of the game is getting flagged as containing a virus (Wacatac trojan), disappointing because it looked pretty solid
Appreciate the comment.
Unity-built games can sometimes trigger false positives with antivirus software, even when there’s nothing harmful.
We've tested the file thoroughly and found no threats using multiple scanners.
If you're ever unsure, it's always okay to scan locally.
Really glad to hear it looked solid to you, and hope you'll enjoy it when you get the chance!
It has also been flagged for me as well, looking at this comment section there are quite a few.
I have never ever had this issue before with any Unity-built game.
I hope you fully address this instead of just telling multiple customers to trust your word when multiple of us, with different systems and software have been flagged.
I am giving you the benefit of the doubt.
Thanks for the report. Just to be safe, I went ahead and downloaded the file myself again directly from itch.io and scanned it using the latest version of Windows Defender. No threats were found on my end.
That said, it’s possible some antivirus setups are flagging it by mistake. If you're still seeing a warning, it would really help if you could share the following:
• the name of the file that was flagged
• the SHA-256 hash (you can find this in Defender’s protection history)
• your Defender version or antivirus software
I'm reporting any flagged files to Microsoft as false positives. I’ll keep an eye on the situation and update here if anything changes.
Also, based on reports that UnityCrashHandler64.exe can sometimes trigger false positives, I’ve removed it from the latest build. It’s not essential for gameplay, so removing it shouldn’t affect anything.
If you're having issues, please try downloading the newest version and let me know if that helps.
Appreciate your help and patience!
Is the full release version censored?
Thank you for your question!
Since this game is distributed from Japan, it follows local regulations. There is no censorship on nipples or other general parts, but mosaic is applied to genital areas.
I hope that helps!
Will you consider to publish it on steam? :>
Thank you for asking!
I'm not entirely sure about releasing it on Steam yet. There's a possibility in the future, but no immediate plans right now. Thank you so much for your interest and support!

I’m the creator of this game.
Sorry, I mistakenly wrote 2024 instead of 2025.
The full version (Japanese only) is already available on DLsite, but due to regional restrictions, the page may be inaccessible from outside Japan.
The English version of the full game is scheduled to be released here on itch.io around April 16, 2025.
I’ll make an announcement once the official release date is confirmed.
Thank you for your patience.
is full version of the game gonna be free to play?
Thanks for your comment. The full version of the game is planned to be sold for $5.
I usually buy from DLsite without any problem outside of Japan, it seems strange to me that I can't see your work to acquire it, however, let's hope you put it on itchi to acquire it.
Thank you so much for your support!
My game is on DLsite, but stricter guidelines regarding uniforms sometimes hide it outside Japan. I’m sorry for any inconvenience.
The full version will be available on itch.io starting April 16 (Wed) at 8:00 PM EDT (April 17, Thu 9:00 AM JST). Please look forward to it!
does somebody know, is it possible to install full version of the game?
I don't think so, the link to the full version provided by the author is broken, there is only a demo here, and there are two options, either he made a mistake with the date since it says 2024 instead of 2025 for the English release, or he is re-uploading an old project, to be honest I hope he just got the year wrong.
yeah, game pretty good, hope to play full game in future, thx for reply tho.
Literally no point to write a full description in english to finally only release a full japanese game :(
looks fun
Looks fun, wish it was in English but it wasn't to bad to figure stuff out.
