If she took care of elderly using her lovely holes, or taught virgins the lovemaking, for free off charge, or with only some fair prices, she would be a saintess in my eyes. It's a public service that can bring much good to the community. An honest work should be rewarded, why not?. There is nothing bad if you like your job, or just consider it as a hobby. Somebody may just like to jack off to Excel's tables, it won't be as bad as if he stole anything, although he will be much harder to judge and receive a condemnation.
If you consider jacking off (reliving your sexual desires) as a sin, then what are you even doing here?
