Torturing of Hotori Mizuno and her pink pearly nipples. Her nipples are really one of the prettiest you can find. Shaped like pink pearls and are hard when aroused.
You can see Hotori winces as Mira drove the needle through her nipple right through the middle.
I can’t imagine the intense pain she will have to bear as the tip of the needle makes its way through her pearl of delight.
Later the nipple is twisted by turning the needle 180 degrees and further poked into the breast. What a way to make torturing a girl’s breast and nipple with a needle more efficient.
