I guess we were due for a part 5 sequel; after all, there were so many unanswered questions from part 1 through 4...
Carnal K.C. is a dream researcher, exploring the unconscious and the subconscious of people's dreams with some weird headphone gadget. This is the tailor-made excuse to dissolve into the all-girl situations. Not too original, but who cares, right?
Britt Morgan strips on her dildo and reams K.C. thoroughly; Marlena Riche laps Teri Diver's quim; Jamie Lee and K.C. coax Marlena into a threeway; Britt nibbles on Jamie's snatch; Melanie Moore and Diver double mount a two-way dildo while K.C. watches. Other than the hot finale between Diver and Moore, things move on auto pilot and the heat barely rises above lukewarm.
No Man's Land 5 isn't lousy, it just suffers from the middle-of-the-road, mediocrity that the industry is so oversaturated with. For needy fans of girl/girl vids it might work.
