【The first of the night】I was seduced by my girlfriend’s sister and we secretly had a reverse NTR lovemaking affair.

Story
It’s a story about how you go to your girlfriend Nanami’s (CV:Aoi Yuka Hyuga) house and her sister (CV:Rito Ichinose) takes a liking to you and seduces you even though she’s nearby.
She gives me a hand job while she’s sleeping next to me, and invites me into the next room where she’s cooking.
I’ve not had sex with her in a while, so I’m more excited than usual, and she begs me and I can’t resist, so I sneak in without her knowing!
I’ll write down the date of my next Creampie in my notebook later.

[I’ll write down my next Nakadashi date in my notebook later]

-I’ll write it down in my notebook later.
There is sex with both sisters! You can enjoy it more by comparing and contrasting!
A new feeling of immorality and the thrill of knowing you might be caught because she’s there!
You can enjoy both the dirty seductive sex from your sister and the loving and full of love sex with your sister!
You can enjoy both the NTR and cheating moods, but the seductive loving sex is also very immersive!
Whispering handjobs, creepy ear licking, voice killing sex, and two ear licking as if they were fighting for each other!

You can enjoy a variety of play!

-Realistic sound.
A binaural microphone KU100 is used for the voice, and the distance to the microphone is reduced to zero in the close scenes, so you can feel the close contact and breath.
When you close your eyes, you’ll feel as if you’re right there with them, in the immersive binaural sound.
