In this volume, Alice and her friends encounter a "spirit of the wind", and fuck her to reward her for helping them to get to the castle.
As far as futanari goes, this manga takes the cake. Explendid artwork and an interesting storyline. And this volume is specially nice, just because of the "spirit of the wind".
Alice and the gang call a wind sprite to help get them to the central palace. After the trip, the sprite says she's had no experience with sex and wants help. So they help her ;). Orgy Orgy Orgy.
Another great volume, this series rocks. Good artwork with a great story = Rarity among doujin/hmanga.
Oh man. I love this series, and this chapter is one of my favorites. The wind sprite helps Alice and her friends get to the palace, and for payment, asks for her first orgasm. It starts off as a normal lesbian scene, but then Alice, Bunny, and eventually Chessie pop some pills and each grow a penis. What follows is one of my favorite scenes ever, with the wind sprite being filled in each hole until all four of the come together. Great stuff.
