<human>: Hi. Throwaway for obvious reasons. 

This also makes me super uncomfortable to type but I will just go ahead and say it. I live with my parents and 3 other siblings, two older brothers [19 & 21], although one is studying and comes home every so often when he's on vacation. I also have a younger sister [11], so basically it's just my parents, my brother, sister and me that is usually at home on a day-to-day basis.

We have an ipad that everyone uses, even though we have our own phones and laptops and stuff. But the problem is, I keep finding porn on the history or on open tabs when I use it. It makes me really uncomfortable and I havent yet brought this up with anybody. 

I know it could be coincidental as in, some random page redirecting to porn, but somebody MANUALLY typed things into there. I know this is laughable now, but stuff like "hot lesbians kissing" or "fucking videos" and fucked up shit like that. I always make sure to just cross off the tabs and clear the history, but I can't bare doing this from time to time. I don't know if it'd be my brother, because he's old enough to know to delete the history and why would he be so stupid to use the ipad in the first place?!

The thing is, my sister has been using the ipad and a few months ago my brother found out on the history that she was watching some dodgy things. She started crying and saying it wasnt here, but I felt like my brother got found out and blamed it on her :/. It's making me really uncomfortable to think that its my little sister, becasue she's completely clueless about stuff like that?!

Can someone please tell me how to deal with this? Its such a horrible situation and I want it to stop.

Can you condense the text into three sentences or less?
<bot>: I keep finding porn on the ipad that my family uses. This has been happening for months, I'm not sure how to confront or deal with it.
