I was in a porn store one time and there were these 2 girls looking at this lesbian tape next to me and one girl says to the other: Look at her butthole, it's amazing how big your butthole can be! I giggled, they looked over and glanced at the tape and said yes thats one wide butthole. A few days later I ran into the chick that made the comment at the gas station and it went from there, dont mean to bore you with the rest of it, it was pretty routine.
