If Albert Einstein had the screwed up family tree as portrayed in The Theory of Relativity, he'd probably be making one of those long distance Sprint calls to Frankenstein on Father's Day. E= MC screwed, if you will.

The Theory of Relativity is a sex feature that asks to you buy into a couple of fantasy/role-playing premises — that Joey Silvera is Jasper's stepfather, although she insists on calling him "daddy",, and that Joey's "real" daughter Danyel Cheeks (actually she's his adopted daughter but doesn't know it) is having an affair with her stepmother Vivian. Or is that adopted step-mother?

As one might safely gather, this isn't your ordinary feature, even by bizarre, rarified "Sodomania" standards. Anyway, the rest of the plot is pretty much up-for-grabs in this nutritionally balanced, but sometimes confusing kink-a-thon that features lots of anal sex, underwear sniffing, the power of suggestion and an occasional trip down the foot worshipping walkway.

While Jasper's out with the dogs one morning, step dad Joey is making a tour of her underwear drawer and comes across some provocative polaroids of her which he jerks off to. Little does he realize that she's got a similar collection featuring him in a variety of peek-a-boo poses. This little horseplay establishes a zesty "dream" sequence (after some nice shower stall T&A which sets the table) as Jasper verbally taunts Joey and he responds by eating her ass and jerking off on her tits. If Joey can't have such things in real life, he gets the next best thing when he solicits hooker Anjelica to serve up an ersatz daughter fantasy for him that calibrates about five body positions, ending with a favorable wet climax.

Meanwhile, Marc Davis an executive for a lingerie company that Cheeks is a model for, is having an affair, like Cheeks, with Danyel's British step mom. The pairing between Davis and Yvonne (a beautiful, elegant-looking woman) features an anal (doggie) but isn't necessarily the most fluidly composed from a visual text, though Davis drops a nice sizeable load in Yvonne's well.

When Cheeks (one of the most improved performers in the business) pairs up with Yvonne, it's a lilting medley of fingers and assholes as Danyel administers a digital d.p. and Yvonne responds by giving Danyel three fingers in the front and two others in the ass.

Off to London on a modeling assignment for the company, Cheeks has a layover with a British babe named Nicyteen and Merry ol' England's equivalent of Will Jarvis, Edwin Bush. The highlights of this encounter feature Danyel taking it up the ass in a reverse cowgirl anal.

Recommendation of The Theory of Relativity comes with an individual proviso: when an irresistible force such as strong sex meets an immovable object like family ties — perceived, fantasy, or otherwise, the waters run deep and are generally unchartered. Bring Dramamine before viewing, especially if you're not used to the weather conditions.

With the story being continued, I think it's pretty safe to say that the sex looks even more arousing, blustery and ribald in the concluding chapter, so be sure to stock both titles. This series is going to generate a lot of controversy.
