Make it clear from the start - your time is yours.
It takes far longer to edit the shoot than it did to shoot it. You are already investing more time in this exchange than they are.
Secondly - no-one gets all the shots. Tell them your job is to take a mixed bag of lemons & peaches & separate out the peaches*. The lemons go in the bin, the peaches get worked on further.
The ones finally used for the presentation 'peach melba with cream' have had all the work done. The ones that made it past the lemon cut but not to the final product are unlikely to be worth their time, no matter how keen they are to see them.
You will send them 6 - 10 images you personally think are the best ones; fully edited & in high rez.
You would be prepared to give them low-rez jpgs of some of the also-rans, just to demonstrate why you picked the ones for the 'peach melba'; but they are not to publish them without prior approval &/or further editing [you might take a punt at trying to charge if they want any of these working on - up to you**]. Otherwise, this batch is for them only.
*If they get argumentative on the lemon/peach distinction, point out to them that you may take 20 shots just checking your lighting, focus, composition [make up some techno-babble if necessary], before you even care what expression or body-presentation they need to do, or whether their hair looks right. That's a big bag of lemons necessary to the process that even you will never look at again.
That's before you even get to the one where they blinked, or sneezed, or their hair blew the wrong way, or they asked you a question right as you snapped… or you missed your focus, or they picked lint off their left boob/scratched their crotch [dependant on gender assignment], picked their nose, turned away, laughed too much, had a funny stare that made them look slightly mad… yada yada…
Tell them lemons are lemons & no-one ever needs to see them out in public. You will quietly & discreetly discard all the ones that don't make them look their best. They did their job, now let you do yours.
**I'd weigh that up against the fact that everything so far on a TFP shoot has been 'free' & wouldn't bother pushing too hard.
