The Stepmother series from Sweet Sinner plays to one of the most popular genres in porn - MILFs. This 4th edition in the series features the sumptuous Julia Ann as the new wife of Tommy Gunn - whose daughter Gracie Glam automatically takes a dislike too. That only intensifies when Gracie's new stepmom makes a pass at the starlet's sexy fiance, James Deen.

Gratuitously melodramatic, The Stepmother 4 succeeds by being beautifully filmed and produced; with a truly delicious cast of stars to enjoy. Julia Ann is especially delicious; and she's proof that ladies are like fine wine, and just get better with age.

There are only four sex scenes in Stepmother 4 - but BOY are they good. Julia Ann stars in two; one with her erstwhile husband, played by Gunn, and the next with James Deen. The combination of Julia Ann and Deen (widely acknowledged as the best looking guy in porn) is electric.

The real highlight is a threesome, though - with Gracie getting down with non-other than SexIs' own Nina Hartley. This stunning porn veteran has been performing for almost thirty years (longer than Gracie has been alive) and still looks stunning.

That being said, the movie itself runs over 2 hours; so four sex scenes isn't exactly a lot. Some critics might argue that this doesn't exactly offer great value for money. Whether it does or not ultimately comes down to how much you value the rest of what the movie offers; including the plot.

I personally dug it. Like most porn films, this isn't going to be mistaken for an Oscar winner, but the script has some sass and the twist in the tale - which I won't give away here - is pretty ballsy. You have to decide that for yourself - if you've become quite the porn aficionado over the years, as I have, it's nice to see some of your favorite porn stars and starlets actually having something dramatic to sink their teeth into.

Ultimately, Stepmother 4 is a top-quality erotic film, with a top-quality cast, but in amongst a crowded market (including many films featuring actors and actresses from this movie; sometimes even in the same sexual pairings!) whether or not you decide it's right for you probably comes down to your particular kink.

For me, the appeal was delightful Julia Ann, the melodramatic plot and, of course, the threesome with Nina Harley. If that sounds appealing to you; this movie probably will be too.
