Snipped from dlsite, the resolution is not that good(also because of the original file), but if one is not reading doujinshi through the 4k computer monitor that is fine.
Buy the original product to support the artist(Yagami Shuuichi) if you can and like it,
and once again thank you P.B.264 for sharing this sexy, active girl, this kind of girl friend is so good~,
