Basically, what is an event that caused a massive chain reaction?
Tonight, I (15F) was looking for my mom's earphones in our living room. No one else was with me, and at some point, I moved a couch away from the wall to look behind it. I found nothing but clothes, trash, and some papers. I picked up one piece of paper that was folded into a small square.
Upon unfolding it, I find a rough colored drawing of a guy's penis cumming into a disembodied uterus. Below it is a question: "Who do you think is having the frickel frackel?" and it just has the word "fucking" repeated 9 times underneath (genuinely no idea what this means)
I could immediately tell by the art style and handwriting that it was my little brother's (10M). I must say that there was a time a couple years ago where he got in trouble for looking up porn at both school and home, so I'm assuming that's when he drew it.
He's currently not home (divorced parents T_T) and neither is my mom (work), only here with my aunt and older siblings. I'm unsure what do to as of now. Any help?
TL;DR: found my 10 yr old brother's porn drawing and don't know what to do with it
