I remember one day I was on a holiday for warm-up books. My brother was on a business trip. My sister-in-law and mother went to the vegetable market to buy vegetables. I took the spare key and took the opportunity to enter my sister-in-law's room. I discovered her secret in the indoor window!34D size, wow!There are three sets in total, one set each of white, black and red.The white set is ordinary, the red set is very spicy, the bra cup is very low, it should be half-covered, and the underwear only has the so-called lace pattern on the front, but the back is all transparent!The black set is very strange. The bra cup is transparent, and the underwear is all made of thin straps. I didn’t know what it was at the beginning?
