tattoo sunburn

So I borrowed a swimsuit from my friend, and it's a white thing. I lay out on the beach for a long time. Then I'm in my own suit, which is a two piece, but this time it is black and green and stripey. I'm laying out next to a girl and someone else, and we are watching the sun set. When I get up the next day, I realize I have weird tan lines!!!! I have a lightning bolt thing on my left hip, writing on my back, and triangles all down my stomach. They really hurt and I regret borrowing the swimsuit as I realize I should have just tanned naked.
