Exhibitionism with Alison - Day At The Beach
The second thing the lining does is allow the material to hold its original shape instead of hugging all the contours of your body beneath it. Think of it like this. Imagine you were wearing a tight shirt with a solid bra, and for whatever reason your nipples were rock-hard. With the solid bra, you'll be the only person that knows what's going on. But if the same thing happened and you weren't wearing a bra, the whole world would be able to see your nipples poking against your shirt.
The lining works just like the bra did. And now that it's gone, this bikini might hug every contour of your body. Every detail of your boobs might be obvious. Do you know what a cameltoe is? You might be about to find out, because the bikini bottom might be hugging every crease and mound of your ass and pussy. Again, there's only one way to know for sure, and that way is off-limits to you.
