The top here is Bruno, a legend of vintage porn who pounded ass on celluloid in the 1970s and early 1980s. The bottom reportedly was straight, a fact that was not known until his porn career was over.
According to several porn reference websites, this movie was made in 1977. That was, of course, before Internet porn or DVDs and before even VHS cassettes. Customers could only buy movies like this by mail order in 16mm film for home movie projectors.
