Perfect Fit (1985)

Diane (Traci Lords) wants to marry Ricky (Tom Byron) since her sister has already gotten married, but she's not sure she wants to go through with it. Naturally, their party hardy friends would like to hold some parties to celebrate the event and tempt them to take up with different partners instead. Such is the thin premise for some really good sex scenes plus a few duds. the best I think are Susan Hart and Peter North, Christy Canyon and a poker player, building up to Tom and Traci last. Tom and Traci are of course given the longest and best chance to outperform the others. The catfight between Laurie Smith and Kristara Barrington is a misfire, but good considering the two hotties playing it out.
