Little Sister's Long and Passionate Masturbation Thinking of her Beloved Onii-chan

School finished earlier, and the little sister, Riko, comes home to an empty house and now has too much free time.
Then, she remembers that her older brother has a personal notebook.
When she tries to watch some videos on said notebook, she notices that the browser is already opened.

What she saw there was a porn site.

Riko gets surprised, but out of curiosity about what kind of porn her brother likes, she watches some herself.
The videos where more explicit than she expected, and the excitement lead to her fantasizing about having sex with her beloved brother.

Now even more aroused, she unconsciously slides a hand to her crotch and begins to masturbate.

From there, she forgets about her initial goal of killing time, and immerses herself in the pleasure of masturbating in her brother's room.
