A three-day, two-night documentary of the spectacular hot springs in the northern region that reveals the true face of the popular beautiful mature woman, Chihiro Akino, who debuted in 2011 as a "married woman hot spring blogger" is now complete! Just the two of them, she and the director hop on a night train and head to Hokkaido, the hot spring mecca! In the northern region, she changes into obscene companion costumes and indulges in sex to her heart's content! This is the only work that allows you to enjoy the cuteness and lewdness of Akino, who looks nothing like she does for a 37-year-old, because it is a documentary!!
