Some will get proper lewd scenes, some will get some sort of flashback renders, some will be shown but not in a lewd way, some will get nothing...not every girl you listed is that important to the story, and some were definitely a one-time thing (Tara).
Tanaka promised to let MC nut in her, so she should get a lewd scene.
Jaye and Tara was teased when Tara was picking him up at the airport (... so there's a chance?)
Jaye and Mallory really needs to be there. Would be so lame without them together. They were teased in the last episode as getting closer together and wrestling topless, etc.
Rikki teased that MC couldn't handle her and her two companions (... careful what you wish for)
Linda teased she'd fuck MC's brains out (... cougar fit)
I can see nothing further with Fiona, bar girl, Lisa, and Tara ... but the rest really deserve proper treatment. Don't tease and not deliver.
