Jacob gets physical...

One day, Jacob, feeling particularly motivated from seeing so many hot, fit girls online, decided to finally try and get into shape. He thought that asking his dad about how to stay motivated would be a good idea. But first, he had to do something... Going to his bedroom, he gets out his laptop and searches for something sexy to fap to.

Jake had just started rubbing one out to his favorite singer, Dua Lipa in her "let's get physical" music video. However, he failed to account for the volume of his moans, and unfortunately for him, his father Walter was within earshot. Walter, wondering just what was so good about today's fap, decided to check out what Jacob was getting off to. "Knock knock! What'cha got that's so hot, kid?" "It's really good. It's the music video for "Let's get physical" by Dua Lipa." "Oh, her... Love her bod, hate her songs." Walter replies as he unzips his pants to fap along with his son to Dua's rocking body. Jacob pauses the video on a nice shot of Dua's toned booty, and they both stroked a bit faster to it for a bit. They stop the video again at shots of her perky titties and six-pack abs, Jake stroking fastest to that last feature. "Say Jake, you really like those abs, don't you?" Walter asks his son. "Yeah... It's because I want my own... I wanna loose weight, get fit, get ripped. Get chicks like Dua!" Jacob answers. "Well, come with me... I think I know how to motivate you... Oh, and bring your laptop!" Walter responds, before getting off the bed and proceeding to take Jacob to his lab.

"Since you seem to like her so much, her body, at least, allow me to introduce to you, THE iBOD! It's a device that allows someone to take on the appearance of anyone they please!" Walter says, presenting a device not too dissimilar to an iPod, likely where he got the name. "So that's what you've been working on in here..." Jacob says "And I know just who to take the form of to motivate you..." Walter says grinning. His fingers working in a blur, Walter scans the still of Dua Lipa on his son's laptop, points what on a normal iPod would be the end opposite the home button at himself, and presses the would-be home button. Upon doing so, Walter was briefly engulfed in a bright pink flash. When it dissipated, Walter looked rather feminine. But as it turns out, that was only the beginning. First, his face changed, lips and brows thickening as it became a perfect match for Dua's. Next, a pair of perky tits grew from Walter's chest, and his hips widened considerably. Finally all of Walter's body fat transmuted into lean, toned muscle, his glutes at a particularly generous ratio, and his clothes transformed into the same outfit as Dua had worn is the music video. "Dua" then struck a few poses to show off her tight ass. "Now THIS is a body!" Walter said in the pop star's unmistakable voice, as much to himself as to his son.

"Every time you hit a milestone, you'll get to have sex with 'Dua'. And the more weight you've lost, the more wild 'she'll' get... Is that good motivation?" Walter continued. Jacob was stunned. He'd just watched his dad transform from a somewhat overweight middle-aged man into a young, fit pop singer that he often fapped to.
