On a dark and stormy night, the two girls carrying a set of Tarot Cards board bounce into the room where the older stepbrother of one happens to be. "C'mon, play with us- It's a perfect night for a séance!" After much relentless pestering, he finally relents, and the two begin to incant in some strange tongue, coming to a crescendo with the words "Presto Change-O!" No sooner do the words escape their mouths when she starts to indeed change, blossoming into statuesque twentysomethings! "Wow--I can't believe it actually worked! Look at me! All grown up now!" Adds the other, "Now we get to boss you around and tell you what to do like you always did with us! Ha-ha!" Again they are relentless, this time with all of the teasing of the stepbrother and his new subservient status. Feeling empowered (in more ways than one?), the now older step-sister offers him a bargain: "Tell you what--If I can change my appearance to look just like one of your bevy of bee-utiful bikini girls stapled to your bedroom wall, then you have to agree to be my slave. Deal? Let's shake on it...." Once the handshake is completed, she begins to change again, becoming the Perfect Bikini Centerfold, posing for him as if she were posing for the camera. "Is this the one--is this your favorite?" she inquires. Replies the other, "Because if not, I can easily try on the look of the girl on your other wall... Presto Change-O!" And she is transformed into another stunning Centerfold, no less lovely than the first, no less photogenic. The two of them can't stop being amazed at how sexy they've become and complimenting each other... The taunting and teasing just becomes more intense--his dream has come true, the Girl(s) of his Dreams are before him, yet as a mindless slave he is powerless to enjoy any of it whatsoever. At this moment, the stepfather is returning home from work and is totally dumbfounded by what's happening. ("Of course, he doesn't even RECOGNIZE us as grown-up sexy centerfolds--he's expecting to find his dorky little stepdaughter and her dweeb friend instead! Let's have some Fun here...") "Who am I? But...don't you recognize me? I'm the Girl of your Dreams... or at least, I could be. Now, concentrate... concentrate HARD. Think of that woman who excites you the most, the one who occupies your deepest fantasies. She could be yours tonight... it's as simple as Presto Change-O!" And they begin to change once again, but in a rather unexpected way. They have been transformed into... his frumpy secretaries from the office? "Well, I wouldn't have predicted this! Looks like someone has a "thing" for his secretary... strange as that may seem. But we'll make you an offer you can't resist--we can make YOUR secretaries become the sexiest secretaries in the entire world, BUT if we do that for you then you must agree to become our slave... Deal? Let's shake on it..." And the changes begin... starting with stodgy shoes into sexy high heels. The rest of the wardrobe seemingly shrinks away: floor-length skirts dwindle away to the point where they can barely contain now robust butts, revealing luscious long legs in the process. Baggy sweaters become almost-too-tight tops, as it would seem as though all of their clothing is a size or two smaller than their new shapely forms would reasonably allow. Lips become fire-engine red, hair become manes reaching down the length of the entire back, their eyes piercing and seductive. "This is SO much better, don't you think?" But he is unable to respond, having himself become a slave like his son had earlier. Not only that, but he has been reduced to the same age as his son too! "We've done it--we've become their Masters... their Queens... or dare I say, their Goddesses?! And if there's one thing that a Goddess craves, it's power...Absolute Power! Come forth, boys, your Goddesses request your assistance," as they extend her hands forward over them, "and we demand your energy!" And they begin to rise, Giant Goddesses, surpassing 8' tall. "Oh... I simply adore this!" "We could never have imagined this result." "All I wanted was to be the Big step-sister, but now I'm certainly the Biggest of them all! But I want more--I NEED more!" ...they wickedly laugh and laugh and laugh... This clip runs 15 minutes long and includes magic control, growth, giantess, strip tease
