妹「お姉ちゃんクソビッチなんで私にしませんか」

Konoka brought home a guy and did everything to him.
Her little sister Sayaka was tired of this.
"You should know my sister is a huge slut," she said.
She showed the guy a video of her fucking another guy.
However, the bigger shock was what she said next.
"I'm a virgin. Fuck me like you fuck my sister."
