During my freshman year of college, there was a girl that i really enjoyed being around. She had brown hair, glasses, was about 5'1, skinny build with pale skin and a nice innie belly button. Well one day, I invited her over to my house, and she agreed to come. We were sitting there hanging out when all of a sudden, she started picking on me about something I did earlier in the day. Well, we were flirting back and forth, and then all of a sudden, she was at my computer. About 5 minutes into her being at the computer, she stretched. Her shirt showed skin right below her belly button, but it didn't stop from just barely using my fingers and spider tickling her ribs. Because of the method I was using, her shirt started rising up until her shirt was up just below the bra line. I made sure to take advantage of her pale bare belly and slipping a finger into her belly button. By that point, she was trying to get my hands off, but I was able to continue tickling her right on that belly. After a good minute of tickling her belly, I stopped and let her catch her breath. It was a very cute tickle, but I realized that just using the edge of my fingertips to gently tickle raised her shirt up and allowed me to tickle well on her belly and in her belly button.
