What do you do when someone finds out you read yaoi??

So I think I just got discovered by my lil sister (a normie btw), she was the last person I wanted to know I like yaoi.
I was a big dumb...
She wanted to borrow my phone for a bit to search something up so I lent it to her... but I forgot that I was reading yaoi on it before. And it just had to be some hardcore kinky af smutty sh*t to add to it. ╥﹏╥
Usually I always read in incognito mode so I could always just quickly click the "Close all incognito tabs" that in the pull down notification thing but for some reason I guess I accidentally didn't use incognito. ┗( T﹏T )┛
And I know she couldn't possibly not have seen it; i mean after getting my phone back I unlocked it and it was the worst possible panel to open to, even I was unprepared for it...
What do I do now?? ╥﹏╥
I'm part of a very strict straightlaced religious family. And my lil sis is trying to act as if nothing happened but she's so bad at it. TT Shes acting strange and awkward...
I'm wondering if I should just straight out talk to her about it. (Like "Yep your big sis is a Fujoshi" *laughs nervously*)
Like idk try to explain myself??? (But what would I explain... "umm you see I enjoy BLs but I was really horny that time and need some good smut...")
And I was looking at the other tabs too and most were all pervy kinky stuff with weird titles, all ones you would never want others to know you read.
I'm so embarrassed rn.
This was honestly the worst possible way for me to be discovered and by my lil sis nonetheless. Tbh idk what to do ╥﹏╥ help me
