She's attractive
She has an amazing body
She has good OWO and CG technique
She has a good personality
There was obvious enjoyment on her side
She's not fake
For me those things are most important, yes she likes to move quickly but the one time I asked not to this was fine, by and large yes she says doesn't enjoy her work but that didn't seem the case with myself.
I wouldn’t call getting wet “obvious enjoyment” it’s simply a reaction to stimulation.
She may well be naturally wet, or have shot lube up her before the booking, doesn’t necessarily mean she enjoyed it.
I once read about victims of rape having orgasms when being raped, so although the body is “reacting” it doesn’t mean she enjoyed it.
You mention that she gave the impression she doesn’t enjoy the job, so I’d warrant a guess that she probably doesn’t get enjoyment from it at all.
