I have nice story with my older sister. I described previously how I found she is wearing thongs. This is other story, but not whaletail so I will post it here. Many years ago we travelled with my family to the Italy for vacation. My sister was around 17 years old and she was in the period of wearing only thongs. It started at home during the package. My mother saw somehow that my sister is packing only thongs and G-string and she was arguing with her. The discussion was something like this:
Mum: I dont have problem you are wearing thongs, I wear them too. But you should change them for regular undies sometimes.
Sis: But I hate regular panties. I feel perfectly in the thongs. Panties look awful in the summer dresses, the lines are totally visible.
Mum: So are you going to wear thongs under your dreses?...they are mostly very short and completely see-through. That is a stupid idea. Your butt will be completely visible, everyone could see it. You should wear some seamless panties under them.
Sis: They are scrolling in my ass, it is uncomfortable. It will be fine, mum.
Then during the vacation it was exactly as my mother predicted. Sister wore leggings, or jeans shorts but mostly the summer thin dresses. They were mostly see-through so you could see her butt and thongs always. I saw that my mum isnt very happy about that. But they were arguing only once. We visited the old city, we were there for whole day. My sister wore light yellow dresses and black thongs (I think it was in the end so her light thongs were all used and dirty). This combination was amazing. The dresses were see-through so everyone could see her black thong wedged in her ass very clearly. I noticed that many guys turned around her and watched her back
. Then my mum started:
Mum: Hey you said your dresses and thongs will be fine. But I can clearly see your thongs.
My sister admitted that this combination is not good. Unfortunately for them there was no solution
. We spent the rest of the day in the city so I think many italian guys had a nice view.
So this was "my sister-thongs-vacation".
