PM-031 - Secret Pleasures: Young Wives' Forbidden Affairs Vol.9

It's an old title, but as of 2022, I'm still watching it on heavy rotation. There are two actresses, but the two scenes with Haruka Aoyama in the first half are the absolute best. Haruka Aoyama has so many works (and it's annoying to search because there's another actress with the same name), many of which are very erotic, but this one captures her scenes in exceptionally high quality. Her expression when doing it from behind, the way she begs for more... everything about it is so erotic.
