I'll post this because I'm excited about it and figured that it might also serve as a heads-up, even though this title might never get pirated... unfortunately, when it comes to NFDM titles, you can never be sure if you'll be able to get your hands on them.

Anyway, NFDM-442 is going to feature a footjob by the looks of the cover, part of which will be done under the table. I personally like Kotohara Miyu too, so I'm very much looking forward to this! The official release date is March 05.
EDIT: I found some more! And boy, does it take a while to go through this thread to make sure that no has posted these before!
JUFD-495 with Serina Hayakawa
How could I have forgotten about this when I had seen this scene so many times? She's at a bar with a guy sitting next to her. She gives him a handjob and a footjob, but can't finish him because she gets interrupted by the bartender (so cruel of the director!).
SW-072
This OL title has some nice under-the-table moments!
IENE-089
For a little bit the girl is under the table in the first scene.
MIDD-641 with the gorgeous Karen Kisaragi (that cover photo doesn't do her justice, trust me)
In one of the scenes she works at a shop and after she gets pleasured by a co-worker, she returns the favour. Unfortunately, the scene is very short and the guy decides to jerk himself off at the end, which I, admittedly, hate, but that's beside the point...
