Add the word "black" and an established series evolves into a black spin-off.
Everyone should miss the early morning bus and be this lucky; arriving at a friend's place to crash for the night, a wayward traveler plays voyeur while watching a couple get in a morning quickie. Later, he walks in and catches her masturbating - that is, until it is determined that she would rather be delivering a deep blow job accompanied by a slow hand. One last scene with another couple completes Vol. 1.
Vol. 2 begins with three black dudes sitting around boasting of their amazing sexual conquests (these deeds are shown via flashbacks). Instant chemistry upon chance meetings is the motivational thread that creates instant rapport and automatic sex between the guys and gals. This immediate coupling is simple and to the point - they get laid. No questions, nothing exotic - just simple fucking and sucking.
Hopefully, a little creativity and diversity will emerge as the series progresses. Until then, bury this in the video rack with the other ethnic flicks and hope that it will blend in your melting pot.
