Input: Text: my friends and i call this the "norwegian checkout"

my friend and i on our last night in vegas picked up some norwegian girls at the club and brought them back to our hotel. i had one of the best sexual experiences as i banged this hot viking against the window on the 53rd floor of the palazzo hotel overlooking the bellagio fountains...it was pretty epic. in my haze of ecstacy i forgot to set an alarm or get a wake up call for the next morning and we had a 12:35 flight. somehow i woke up at 11:30 and realized how late we were. i used to do a lot of gambling back then so the hotel comped me a lot of stuff and when i called down to the desk they said to hurry and anything forgotten would be mailed to me free of charge and that they've already checked us out. i had no time to shower, brush teeth or any of the usual morning routines. when we got to the airport, i reached in my pocket to get my wallet to pay the cabbie and saw that my hand was covered in blood. yes, she was on her period and i had no idea until this moment. i'm a bit of a germaphobe so i immediately start to freak out a bit but i have no way to wash my hands as we were barely going to make the flight(somehow we made it in time) and i was unable to investigate what condition my junk was in but was sure it was messy. after the worst hour of my life, the seatbelt sign finally went off on the plane and i was able to go the bathroom. i immediately pulled my pants down and started washing my balls in the sink, it was pretty tall so i was awkwardly standing on my tippy-toes with my junk in the sink. in my distracted state of mind, i had forgotten to lock the door to the bathroom and an older gentlemen opened the door to find me in this precarious position. he stumbled backwards with the most surprised look i've ever seen to this day. i sat in the bathroom for about 20 minutes freaking out wondering how i was going to leave the bathroom and face the people on the plane. surprisingly, no one said anything to me and after the 4.5 hour flight i landed back in toronto. as i walked off the plane, 3 security guards asked me to come with them. this guy had told the flight crew that i was masturbating in the bathroom. the security team interrogated me and i told them the whole story and they were killing themselves laughing. one guy couldn't keep it together and was keeled over the table crying. they then said it was one of the funniest things they've ever heard and said they'd let me go because cleaning myself is not against the law and said to lock the door next time(thanks captain obvious). that's by far the most embarrassed i've ever been in my whole life.

TIFU by forgetting to lock the door.
