XV-867 At someone's mercy Yuui Hiratsuka

The thrill of being able to do whatever you want with the obedient "Yui" is even more exciting!!! She likes being teased, and her sweet, sticky moans as she's relentlessly stimulated with a vibrator but not allowed to climax are a turn-on!!! Although she's a tsundere character who plays with her big brother's dick, in the end, she melts and begs, "Put it in quickly... Don't pull out..." Even more so, the scene of her as a young wife being ruthlessly pounded by an old man is criminally erotic!!!
