Stories Like Sapphic Serenity by BiscuitHammer

I recently found Sapphic Serenity by Biscuithammer. Love love love the taboo relationship and water sport play between mother and daughter. I am looking for mother mother/daughter stories like this that may not be tagged with mother/daughter on Lit or elsewhere. The only other story I've found not tagged has been Amsterdam: Weekend of Kink.

Any suggestions?
