In truth, no one can say "every" or "none". It only takes one gal, one time, to make a liar out o' you.
In the SubAMPs, the spa sets a standard. MMS sets her limit. Each gal sets her limit. (No nudity. No touching. No full sex. No getting caught. Make a woman out o' me, big boy.)
We've all been to L-NO places and scored. And, we've all been to sure-thing places and been shut down.
And, then there's places like 15th street, where you'll probably get a secret handie during the week & ass-slapping, ball-licking, dirty-talking FS on Sunday ("Boss no heah on Sunday.")
