My little sister(turned 18 Friday ) is technology challenged was helping her with her IPhone earlier.. was messing around in the settings trying to empty out storage.. popped up with files and majority where guys masterbaitin..

It was also strange that she has a text free app on her phone....

she also has me(22) and my other little sister (21) blocked on all social media...

my cousins have access though and I know she’s posts risque things...

But like what is going on ??

I know like two years ago.. she got her phone taken away for a week or so, since my cousin told her mom what my sister was posting.. some shower tease stuff... who in turn told my mom; she completely denied it and got into a huge fight with my cousin.. I’m taking fists.. my parents had no evidence but my mother insists that she posts only godly things ... but with snapchats new Private story options Who knows

Id ask her but she’s a pathological liar...

is this normal teenage stuff? Or I’m over reacting

Or could there be something there ??
