Bikinis smaller than tan lines
 

I love it when girls wear bikinis wich are so small you can see the white area left by previous worn larger bikinis..
thos is an example pic of my wife Cinzia with a micro bikini on the beach, you can easily notice the white mark of the normal bikini she used to wear( which by the way was also a thong...)

gonna need more dude! ur wife is hot

Here u go!
But I'm sure there must be more out there!

bringing this thread back to life
 

bikinis that are smaller than tan lines reveal the fact that the woman is wearing something she wouldn't wear normally or at least not all the time. In other words, these are fairly "normal" women that want to feel sexy and give in to their own or their partner's desire.
