Stories of lesbians or wlw having strap on sex but there's a plot and even a conflict.

[Futakween]

Hi, I'm looking for strap on sex stories between female characters. I would prefer the story to have a plot, well written preferably by a female author, and also have conflict. Bonus: the person wearing the strap cums, two women with straps fucking one woman.

I remember coming across a story like that a few years ago by a black author that I haven't been able to find since; it was so hot! Nonetheless, if able, please recommend such stories.
