My initial instinct was She would go with the highest number, but then I thought She would expect that so I guessed four. Of course She was one step ahead of me & predicted my reasoning. So it was five.
Turns out she had a crush on a guy that was going to be at the party and bet her friend she could fuck him with me there. She obviously won. They fucked by the pool and she had me lick her clean in front of everyone.
