YNOT – Chatsworth, Calif.-based JM Productions has added two websites to its Gag Factor affiliate program, doubling the number of membership sites affiliates may promote. HardcoreFuckMachines.com and OverStuffedHoles.com feature hundreds of photographs, downloadable clips and exclusive bonus footage of women undergoing extreme penetration.In addition, the new sites offer members a unique behind-the-scenes look at JM Productions’ shoots.

“We realized that the fan is curious about the technology that we use to ratchet these whores’ holes open that wide,” said JM Publicist Tony Malice. “Each site has a bunch of behind-the-scenes footage where you can really learn more about that technology and the mentality of the cumbuckets that are subjected to it. It’s awesome.”

Members of both sites automatically receive access to the other plus the company’s other sites, GagFactor.com and AmericanBukkake.com at no additional cost.

Like their sister sites, OverStuffedHoles.com and HardcoreFuckMachines.com pay 50-percent revshare. The affiliate program is managed by CCBill.
