Looking for a story

[Quicksand_Hex]

I read a story in the past couple weeks that I haven't been able to refind. I don't know if I saw it here, searching through old deepsinking stories, on deviantart, or just a story on the web.

Anyways, the story involved two characters, a male and a female, taking a mud bath. When they were trying to get out, the female was on top and the guy was trying to pull them both out, but he didn't realize that the rubbing of the two of them was turning on the girl, and she ended up cumming without him knowing by the end of the story.

Thanks for any potential help.
