Swing & sway with...

...a whole bunch of vintage guys showing their stuff back in the early Target/Colt era when you could still be prosecuted (under obscenity laws) just for jerking off on camera. All of these guys were hung, but only a few would be considered monsters these days: Bill Eld 00:30 & later, and Enrique Nieves (00:44 & throughout) as well as Toby (in the closing shot.) Bruno puts in an appearance 01:05 & 02:20, and Dick Trask, Erron & Denny are featured as well. In the erotica business, these loops were known as 'danglies'--i.e. frontal nudity scenes where physical activity (running in place, shadow-boxing & dancing) were used to showcase the family jewels.
