Hai chị kế đĩ: một câu chuyện hoang dã có thật - Hibiki Otsuki, Yui Hatano

Hibiki and Yui have a lot of free time and are chatting over a cup of tea. The content of their conversation is about their own naughty experiences. While the conversation was going on, the two men who had also appeared in the conversation came to the house together. Hibiki and Yui, who are truly lascivious women, are in a slightly naughty mood, and they ask the men to have sex with them.
