Got the best Rakshabandhan gift without even asking
So before I start I want to make sure that this is a 100% true story that happened last night and I'm still in shock and just wanted to share it with you guys for suggestions
So a quick background story:- my sister doesn't own a phone yet and she uses mom's phone for almost everything from clicking pics to using insta, whatsapp, etc. so mom's phone is filled with her pics and screenshot of notes from class and everything a girl does on phone from screenshot of shopping items to random art pics.
Main story:- so every once in a while I open mom's phone and clear her gallery of all the unwanted pics and screenshot that are no longer needed, so I haven't done it for a long time so I decided to do it last night just before going to sleep around 12:30, other family members were already fast asleep.. so once I cleared everything from the Google photos gallery I went to the bin to wipe It clean but for some reason I decided to check the bin top to bottom before clicking delete and boom that one decision changed my night.. as I scrolled down I saw a video of my sister in her bra, I thought it was nothing and kept scrolling since it was surrounded by pics and Google photos has a feature that if there is a video it keeps playing in the background and suddenly I noticed that she is taking off her bra, I clicked the video after a moment of hesitation and what I saw shocked me first, then I got angry, then I got excited (which I feel so ashamed rn) in the video my sister was posing naked showing her boobs and pulled her panty down and showed her ass... And it was not one of those videos people record by mistake she made proper eye contact with the camera and was possing non stop for 27 seconds.
Before you guys run to conclusions let me tell you I have never felt any kind of sexual connection towards her, I love her a lot as a sister, never sexualized about her but after last time something changed.. I was angry for a long time but I ended up fapping twice since I discovered the video, now I am unsure if I want to confront her or let it go... And if I even confront her what do I want to do exactly, do I want to have sex with her or just want to have a fight.. I don't want to tell my parents as this will only lead to stressing them up even more.. and the fact that I transferred that video to my phone and kept it in a secret folder is making me even more anxious to act on it but I don't know how to... She is a very angry kind of person and gets mad at the slightest of discomfort, when I'm horny I feel like I have to confront her and train her how to have sex and stuff since I know for sure she is a virgin but when I'm not horny I feel like I need to forget this and move on with life, whatever happens I have a trauma for life and I can't see her the same way every again...
So that's how my sister gave me the best/worst gift this rakshabandhan and she doesn't even know about it.. the fact that when she was tying the rakhi on my hand all I can think of was her breast and they were lovely.. please suggest me how to deal with such a situation and if any one of you by mistake discovered nudes of their family members and how did they dealt with it. Any help is accepted
And please don't ask me for the video in chat or in comments
