There is a
boiler-plate way to make this fantasy happen...
It does have dangers though....
Find a cheap pool hall and visit at about 10:30PM -- it works best if you go alone (or at least appear to be alone). Dress for sex (not sexy but sleazy) ie: no bra - no panties - short skirt.
Find the table with the four or five young (18-25 yo) guys who have had just a little too much to drink. Ask if you can play too... One of the guys will say "you can play with me anytime baby" (they learn that in the guy book) -- you have to reply with a come on or they'll back off... say "I like to play with everybody"
While playing around show your bare bottom as often as possible without flashing the bar maid (she'll think you're a hooker and toss you)... Make sure that you tease everyone equally or one of the guys will take it as you're interested in him...
Let the guys take it from there....
Don't screw in the club (unless the owner is involved) and take your own rubbers (at least 8)
