The last 2 pics reminded me of my scuba diving trips years ago.
In both trips, there were a couple of gals whom were clad in this type of black, bikini top and like to walk around on the boat dressed like above manner.
Interestingly, these gals also had similar tits size as above gals. Lol
And in the first pic, can see that she didn’t wear any bikini underneath that tank top. Sweet looking Japanese girl.
