Ivory Tower studio – of FuwaKumi, Mix Peace, Nana’s daily work fame – returns after 4 years of silence with a new work “Rina to Ana” / Rina and the Hole. Rina is a “would-be” gal! She often takes a cocky attitude despite her lack of experiences, and is now stuck in the playground and can’t move at all! Then out of nowhere a depraved boy comes to take advantage of the situation… Rina exposes her butt so defenselessly! But don’t worry, she can’t see your face! Enjoy this situation which comes with a sense of guilt. Voiced by Kaede Akino. Her moans alone is worth the watch! Which side of Rina would you like? We have also included a side-story as a bonus!
