WARNING: This is something that might be highly disturbing, so a fair warning before I actually get into writing about it. Read on at your own risk! 

An online post by an unidentified person (presumably a girl) has netizens in an uproar due to its slightly graphic, incestuous nature. 

The post read, "I was looking for something in my older brother's room, and when I found my used underwear and pad in one of his dresser drawers, I was so shocked that I haven't really talked to him much for over two months..really...I can't even tell anyone about this so I'm really frustrated..just what did my brother do with my things, was I not just a sister to him? Just what was I to my brother T_T what kind of thoughts did he have looking at me day and night? I feel so regretful and embarrassed about wearing such revealing clothes during the summer...I'm having such a hard time.."

Some of the netizens left disgusted comments on the post, writing, "Guys are seriously the worst. They will even smell their own sibling's underwear. Just watch out," "My little brother who is four years younger than me always tries to come into the bathroom when I'm showering with the excuse that he has to either go pee or poop..what do I do?" "Used [underwear and pad]? Tell your parents.." 

But what's even more disturbing than the story relayed by the OP is some of the comments left by the netizens, who had their share of traumatic, disturbing tales that will leave you feeling....well, dirty on the inside. "Ah, I suddenly thought of a really creepy story that I read elsewhere...[someone wrote that] during her period, she thought it weird that her husband would always use the bathroom right after she was done, so she decided to check one time and found her husband licking the pads -__-......." "When I was in grade school, I was sharing a room with my brother who is two years younger than me, and when I woke up one day, I noticed that my pants were off even though I clearly remember going to sleep with my pants on and [my younger brother] also had his pants off and was rubbing his privates against mine with nothing but his drawers on. At 2 in the morning. So shocked. As soon as I saw him I yelled at him, 'WTF ARE YOU DOING!!!' but he just stayed still...ever since then my brother and I acted like strangers. It's even more shocking that he did that at such a young age...even before I had my period..I was in fourth grade and he was in second grade..who would believe this....I never said anything for 20 years but I write it for the first time on here..." "I use the bathroom inside the master bedroom right? Because all the women in our household use the master bedroom bathroom. But my older brother who always used the living room bathroom would use the inner bathroom every time I got my period...when both bathrooms have bidets," and, "I...I'm having a hard time because of my older sister...when my sister is doing her business in bathroom...she always leaves the door open...I know she has claustrophobia but I get really stressed...Noona please when you're doing your business think of your brother...it's okay if you don't close the door all the way just enough so I won't be distracted...please noona....I'm sorry for writing a comment like this on here...T.T."
