This is another one of my favourites. The elder sister here is a sexy manipulatrix who is the perfect mix of dominance, possessiveness, and jealousy. The way she makes demands of her brother is so fucking hot, and I love how pissed she gets when he doesn't immediately give her what she wants. Her look of contempt is so compelling, and she follows it up each time with indisputable proof that otoutos and anekis belong to each other. This is a sister I would absolutely let fuck up my life.
