Several years ago my girlfriend was into tanning salons and, if I had nothing else to do, I sometimes went with her... A couple of times I have jacked off while thinking about my girlfriend tanning naked in the booth next to me.
My wife, who's very fair complected, got a gorgeous tan for me while I was away from her this summer (she stopped in Spetember and I can still see her tan lines). She wore only her bikini bottoms, tanning everything else. I got so hard when she told me that not only did she strip and change there in the booth, but that she was tanning topless. So hot!
