Character
DokiDoki! Hentai Health Checkup [Twin-Tailism]
Name: Nana Tanaka
Height: 156cm
Breast size: ???
Prim-and-proper. Her bountiful bosom is growing by the day, which you can see from the strain it puts on her shirt buttons, and causes her issues when it comes to choosing her outfits.
She's a bit naive when it comes to love, but she's secretly interested in sex. She has no idea that even the smallest motions can send men's hearts aflutter.
When she moves with full force, everyone's eyes are glued to her openly bouncing breasts.
Kind and has a hard time saying no, she often finds herself in embarrassing situations as a result of agreeing to things she hasn't thought much about.
Examination
DokiDoki! Hentai Health Checkup [Twin-Tailism]
1. Check over the forms
Before the examination can begin, you have to make sure she's filled out all her forms correctly!
This is also where you'll input your name (though you can leave it blank!)

2. Breast Examination
Use your stethoscope to listen to her chest. And her nipples. And then also maybe touch them for good measure.
Have fun making her blush!

3. Lower Abdomen Examination
The health of your lower abdomen is very important, so you have to very carefully check her pussy, her ass, and even her asshole to make sure things are fine and dandy.

You need to use some "special tools" to examine her internally in this scene...
After examination...
