There was this one girl I knew back in college who had the greatest innie I have ever seen. An inch deep, just over a finger width wide, and beautiful to look at. All manner of lines and folds ran along its wall until they reach the bottom which was flat save for three little bumps in the triforce shape. Whenever she even slightly moved her stomach it seemed like you could see something new in her navel, and she loved to show it off in cropped tops.
At a party/sleepover I got to touch it. She was wearing a crop top that left a good few inches of stomach showing, so I slipped my finger in and wiggled it around as a joke. She laughed it off, so I did it again. Honestly, I think I could have found a chance to lick it that night if I had been brave enough because I feel like we had a bit of a thing but sadly she moved to Canada shortly after. I can only imagine how amazing it would have tasted, but I'm just happy I got that night to remember.
