I'm not familiar with the titles that you've mentioned in your initial post...but I can highly recommend one of my all-time favorite porn movies. It's called "Flesh and Blood" and it stars a once really popular porn star from the late 80's - 90's who goes by the name of Kurt Young.
Director Jerry Douglas' outstanding Flesh & Blood understandably swept almost all of the major 1996 gay adult award shows, including wins for Best Video, Director, Screenplay and Actor.
The plot pretty much runs as such: When his twin brother is murdered, Derek (the amazingly gifted in every sense Mr. Young) discovers a complex web of deceit, lies and mystery. Assuming his brother's identity, Derek reconstructs his late brother's life through a series of erotic flashbacks. (And pretty much won me over as a fan for life.)
Featuring a solid story, terrific acting and photography, and very hot sex, this multi-award winning video starts as a routine "whodunnit?" and steadily builds into a bizarre and exciting "who done who?" Sizzling, inventive sex is sprinkled liberally throughout. The fantasy scene where Kurt fucks his "twin" is a stroke of masterful editing, and the liberal use of bananas during a super-hot four-way scene forever changed the way big-budget gay sex was filmed as well as what I now think of when I hear the term "fruit salad." Rarely do "plot porn" and fierce sex mesh so damned well.
