I get these weird red lines on my stomach after sitting?

Okay, so I definetley have a flat stomach, and I'm pretty toned so its weird that whenever I sit if I stand up I get red lines across my stomach. They're not stretch marks or anything because they disappear after awhile but they're still really weird. Anything I can do to stop this?
