Krista Allen is indeed a knockout, and you do get to see a decent amount of her in this movie. Most of the other actresses are very attractive as well. All of them did really well with their orgasms. There were about three good sex scenes. The rest were just okay.
This movie could have been something really memorable though. All the sex scenes needed to be longer and filmed better (I HATE that "merry-go-round" technique). There were several times where Krista should have been completely nude, but she's partially clothed. The dialogue and plot were really, really bad, and much less time should have been wasted on them. Oh, and the opening theme is without a doubt the most laughably bad song I have ever heard in my life.
