Input: Text: first off, i know i am incredibly lucky and this may sound a bit braggy, but i realllly fucked up last night.

me and my gf of 7 years have been talking a lot lately about experimenting, and she agreed on having a threesome.  after a bit of searching, we found another girl who was down.  so, i'm extremely excited last night, and decided to jerk off beforehand so i wouldn't finish too quickly.  we meet the girl, have some drinks, and get back to our place to have some fun.

well, the combination of nerves, alcohol, and having jerked off only about an hour before made me unable to get it up.  two chicks all over each other, and me sitting there with a wet noodle.  i've only had trouble maybe once before in my life, but this was at the worst possible time.  who knows if i'll ever get the chance again.

TIFU by "preparing" before a threesome.
