I come in to find Star doing something weird on the couch... it looks like she's masturbating... but she's only touching her belly! I'm curious, but skeptical, but she convinces me to try it out. So I take my shirt off and let her help me. Star strokes my cute belly button and starts playing with my piercing. I start feeling tingly, and even get a little wet. Star keeps playing with my belly button, fingering my belly and driving the sensation straight from my belly to my clit! I can't help it, she actually makes me cum just through my belly button! This is why we're friends. Because she taught me all about how to have a bellygasm! And now that I know how to get myself off through my belly button, I'm going to do it all the time!
