Spank her!

You tell her to turn around and rip the thin fabric open down the seam on her back. You tell her to hold the fabric apart, revealing her round ass. "Since these ladies let themselves get wet with the holy spirit instead of their own sin, they will be delivering your punishment. Each of the good virgins of the church will give you 10 strikes on the bum" you say to the group.

The other women giggle and line up in front of you as their friend tries to look defiant. The first one starts smacking her on the butt, and she seems to enjoy the jiggling. By the time the 3rd woman is done, she's starting to whimper while getting spanked. After all the women have their ****, you tear her clothes the rest of the way off before guiding her to the pool. With all the ladies soaked, you ask them to gather in a circle for a prayer. Their nipples are hard from the cooling of their wet lingerie. Everyone holds hands, and you tell them that it's time for you to give their virginity to the church.
