Good evening people,

So I was walking in front of my library and heading to the cafeteria which is peculiar since I always buy my food first and walk in the opposite direction. I was wearing a hoodie since it is the winter and very cold outside. 
The hallway was very crowded and loud and I got a phone call from my friend. Since I couldn't hear him I instinctively walked into the washroom to talk and walked to a sink. Normally, I take the first door on my way to go to the guys washroom and the door after is the ladies washroom. 
But because I was walking in the opposite direction, I accidentally walked into the girls washroom. Looking down and focusing on the phone call while wearing a hoodie I just stared at the sink as I kept talking for a minute or so. 

Then my friend mentioned a girl who we can call... "Jenny". Jenny was a girl I dated in hugh school. And she was a hardcore Christian, but she was sexually repressed before I started seeing her and let's just say we committed many sins together. Somehow the conversation lead to her and I started bragging about all the things we did and how I "christened her lovely tits with my holy water after getting a bj just before she had to go to church" 
Then I looked up and in the reflection of the mirror, I saw stalls lined up to the wall and thought it was weird. But my brain wasnt ready to accept that I did something as embarassing as walking into a girls washroom yet. To my surprise, a girl walks out of the stall sees me and I wonder if I should tell her she is in the wrong washroom. I think to myself that it must be embarassing for her and just chuckle as she rushes out. Then another one gets out of the stall and walks out.. And at this point I start to notice that there arent any urinals in there. And realizing what I just did I walk out frantically and go to the hallway hoping no one spotted me. Then I see a third girl heavily sweating come out. It was Jenny's goody two-shoes younger sister...
<bot>: Walked into the wrong washroom to talk to my friend. Bragged about a girl I had a raunchy history with and her little sister was in the washroom at the same time and heard the entire thing
