She took out her phone and leaned against Riku, texting both of them. After a few minutes she looked up at him.
"Kaori-san says she'd like to go karaoke with us. Yumi-chan says she's busy and apologized. She also sent me a picture of her boobs."
She showed him the picture, and it was Yumi all prettied up, not that she wasn't ALWAYS pretty, and wearing some idol dress, which she pulled down to get her tits out and then put up a peace sign.
