Yes it is.
A woman's beauty will fade with age. Something they (beauty/body/etc.) openly flaunt in your face while younger. So they might as well CASH IN on it while they have it. Shooting porn, giving you $150.00 foot jobs for a pair of new shoes they want, whatever.
Settle on a dollar amount, make the magic happen, get them to do what YOU want without the talk back. You get to enjoy some time with a woman who looks good for a few hours, suck and fuck them six ways from Sunday, and pay them to go away so you can get back to work. Beyond that, you owe them nothing.
Only thing better is being a back door man for a married woman. No responsibilities but to come when called, provide 'services', and leave. No daily calls, no presents, no anniversary, perfection.
