Saeki Yumika, known as the strongest nymphomaniac. She's a strong woman that you'd usually never be able to handle, but with the use of certain techniques, she becomes an easy plaything. In this work, we thoroughly play with Yumika. She can't perform fellatio, she can't use lewd language, she's too shy to do anything... We enjoy watching her like that, playing with her as if she were a dog or a snake, transforming her into a new creature called "Okoh" (vagina). In the end, she's buzzing with a nipple buzzer, moaning non-stop. Such a cute and strange Yumika, you won't see anywhere else.
