Onii-chan to Watashi no Kiroku 03 ~Echina Haishin~ (d_723867)

On the way home from buying ice cream with my sister.
“Oh! It’s already this late! I’m going home first,” my sister said as she hurried off.
I arrived home late and was about to put the ice cream in the freezer.
Then I realized I’d forgotten to return the manga I’d borrowed from my sister, so I approached her door to knock lightly.
Suddenly, I heard a soft moan leak from the gap in the door.
“Hmm…! Hmm!… Does anyone want to see my pussy?? ////”
I gently opened the door a little and found my sister sitting in the dimly lit room.
Hiding her face with a mask, she ran her hands down her lower body, making a squelching sound as she indulged in masturbation.
If I kept peeking, my sister would find me…? ?
