Machi - She Has A Strong Sexual Appetite. Even Her Classmates Are Scared Of Her 2

Is such a girl allowed to be here? I've had a lot of encounters with many girls, but this one took me by surprise. At first glance, she looks serious, but behind her looks is a bottomless sexual appetite. I wondered if sex can be this good when the body chemistry is good. The only sounds echoing in the room, covered in sweat and water, are the shaking of her hips and Machi's moaning voice.
