【Studio Rain / Unni Koishikawa】[Binaural] Secret Date with a Caring Older Sister [Hi-Res].

Secret date with a caring sister

Story
You get on the train and come to the front of your sister who is sitting on the seat.
You can’t help but get an erection as you peek at her boobs through her loose bosom.

It’s a good thing that you’re not the only one who has an erection, although your sister knows that you’re peeking at her boobs and even getting an erection from it.
Instead of getting angry, your sister is attracted to the large object and takes you off the train.

This is the reason why you and your sister start a one-day date.
Outdoor play, play in the bath, and even cosplay sex and raw Nakadashi!

I met her for the first time and she did this to me.
Enjoy the naughty sex of a caring older lady.

Character
Mahiru
A naughty and energetic older sister who gets off on seeing her crotch bulge with an erection.
Of course, she’s willing to do anything that’s dirty.

On top of that, she is also a hard worker when it comes to making others feel good.
