Looking for a story Shopping with boyfriend's conservative mom

[Reader_123]

Hi, I am a looking for a story in which the woman goes for shopping with her boyfriend's conservative mother and there in the changing room the mother sees her slutty underwear and proceeds to ask her to try conservative ones and then gets her off with great irritation.

I think it was in some top list but I'm not sure. I've been looking for this story for a while but no luck with Literotica search.

Thanks to anyone who can help!
