This tape starts with one position, stuff which gets boring before long.  Next, a body builder works out with his lady on the weight bench and then a nearby mattress.  Again, the action's a bit slow.  Next, it's back to the weight bench for another guy/girl couple.  (Sets and performers are frequently repeated in this series.)  A few more standard couples scenes follow.  Then three couples get down in a pretty hot scene which closes out the tape in memorable style.
