I'm a bit confused how to tag this with "female:cheating" or not. Is hiroshi's wife still frustated and cheating on him from page 26-28? but on page 29 she's still like good wife who want seduce her husband so he won't get bored on her and, on page 30 was she apologize to him because she had ffm threesome sex with her husband before when he's still tired or was because it was related to page 26-28?
Orgies are Ikuyo's idea of spicing sex up for her husband. The 6-pager at the end is Hiroshi's delusions that led him to go down again on the last page. They were having orgies, but when Hiroshi went down, they stopped (he's mentioning his wife is managing things doing it with another woman). He essentially NTRd himself in his mind.
