[Animation] Robin and Oli henshin! (Pixiv Fanbox)

I made a poll on baarag to decide what setting you guys wanted for my OCs and Magic (fairies, witches) won! So, the story of this world is: Witches need to harvest magical power of living creatures to make ther potions and spells, and the best way to do that is through sexual estimulation! Fairies are guardian of this realm, but they can't intervene directly. For this reason a fairy named Lunalight choose 2 girls to be help her defeat a witch who made the little town where they live her nest! Those girls are Robin and Oli! And the witch is the older sister of Mephis! (She is a witch too). I just wanted to make a transformation animation for them, and soon I will star with the lewd renders XD Hope you guys like!!!
