Market for girls?! For me, the thing about gloryholes is mainly to admire them genuinely enjoying a horny good time... just like those 2 ladies sitting by the bar enjoying the show.
Legendary scene. If I was a producer I'd make a scene like this but with more holes and more Girls. Make it a three hour epic movie with lots and lots of facials. Super heels would be worn as well. Gotta get rich, my friends...
