Poll, Which character? (Aqua, La+, Shion, Ui and Iroha)

I want to do something with multiple poses, doujin-like with the theme of a fellatio where she starts from disliking it until she is enchanted by the act.

The image is just the first panel of page 1, it will have 2 or 3 pages.

(I want it clothed , boobies will be added if needed).

At the start I was going to draw Gura again but with how the theme is about dislinking it I changed the possible characters, I think all would fit the scene, my top chocie would be Shigure Ui or La+, but still can't decide.

(Aqua, La+, Shion, Ui and Iroha)
