The new gonzo sites cover several popular niches including anal, teen, girl-girl and gangbang.
"We're excited to add these new products to our portfolio, and to give our webmasters more fresh, premium-quality sites to promote," Busick added.
Four of the five sites within Top Bucks' new gonzo line had previously been marketed through the X Money affiliate program, which shared elements of Top Bucks staff and infrastructure.
Former X Money General Manager, Q Boyer, said that the move of the site to Top Bucks was spurred both by a desire to make the most of the sites and to support the new products as effectively as possible.
"While X Money was picking up steam, Top Bucks simply has far more resources to work with," he added. "We felt that by moving the sites under the TopBucks umbrella, webmasters would benefit from the larger support staff, more developed technical infrastructure and substantial human resources that TopBucks offers."
A variety of promotional tools are in place for the new line of sites, including a wide range of banners and plenty of hosted picture and video galleries.
