I accidentally have access to my GF younger sister I Cloud

So to give you context me and my gf have been in a relationship for close to 2 yrs now.

Few weeks back we went out with her sister as she was buying her 1st i phone (ps- she already had ipad before this will come into context) So her sis is in graphic designing and all so she have had this i pad for like over 2yrs i guess…. After we got the phone she was like i need more storage and suggested that i upgrade my plan to family plan and it will be cheaper that way and i was like of we 4 already share a Spotify plan (ps- i also have my younger brother on the spotify plan)

So I was like why not and we agreed we got her some accessories as pre birthday gift and later went to my place….. Now she logged in her id in my mac and to setup tenet in my family plan bla bla bla….

But i noticed something yesterday i was searching my cloud for some old clg photos (one of my friend is getting married so I thought will frame those old pics will be a good momento or something)

Then I noticed she haven’t logged out and look out of curiosity (i know i shouldn’t have but i thought i will find some really bad pics of my gf and will use that to tease her or something)

First i stumbled on some tasteful photos kind of revealing but nothing too serious and i should have stopped there but i went on and opened a pandora box…. I saw her nude some vedio of her touching herself and more stuff…. Idk what to do now… I part or me is really turned on and wants to seduce her and i know that would be wrong but that sound of her moaning is echoing in my head…. I am so conflicted rn have jerked off to her so many times by now
