a slick, sensitive amateur who has an i-cup milking while wearing a quiet face

Tsukuba-chan looks like a serious atmosphere, but she is actually an amateur who has a gap in love with H. It's a man-made machine that has a bit of a male-dependent habit, and when called it will turn to the hoi hoi wuwwuwwhwu so cute you can open the hoi hoi with pipan white skin moe deca milk. I'm jealous.
