Kirika wakes up and decides to go to the toilet. Just then, she looks at Chiharu's butt and sees you.
"My, who do we have here?", she happily says, and picks you up.
"He..." you start to say, but she interrupts you.
"You know, seeing you so small, I fell like tormenting you a little. And since I was going to the toilet, I think I know how." She then lowers her panties, puts you in front of her butt, and farts loudly.
*W-what are you doing?" you say while coughing. She, however, is not listening.
"Sorry, but my farts smell unusually bad, and I donn't feel like sniffing then myself. You don't mind, right?" she then puts you on the couch, sits on you, and farts again, laughing.

You start coughing more and hope someone helps you...
