That reminds me of a similar experience i had in highschool. A female friend i used to sit by in art class had many piercings in her ears, a stud in her nose, a tongue piercing, and the belly button. I knew she had a belly button piercing and wanted to check it out but never had the opportunity. One day we had a chance to get extra credit by doing an extra drawing of whatever we wanted. We had "A's" in the class so just fooled around with the idea she drew a stick cat or something super simple. I told her i was going to draw her piercings. She excitedly told me that was a great idea turned towards me and began to show me them one at a time. After i drew her tongue ring which was the final thing on her face. She just faced forward at that point so i did too. A few seconds later she says oh yeah dont forget my belly button, stands up and lifts her shirt. There it is her cute belly button right in my face, im not even really into piercings but it was still nice and a good excuse to see her belly button. It was a small innie and i got to move the ring around a bit. I wish i would have poked it :)
