While your son was still out at the gym, you had returned home to discuss the plan of action with your new inner companion. "Here's how I figured it," he began to explain. "Your son clearly is at odds with his new inner self; she just wants to pleasure herself, while he wants to live a normal life. He's barely managing to maintain an equilibrium with all those toys of his." You nod, having noticed this yourself. "So what is it that you're suggesting? What device do you have in mind?" You inquire. He replies, "I recommend we use the sizing remote, to increase the erogenous areas of his body. Increase the size of his breasts or something, and simple toys won't really do it anymore. His horny, inner milf self will end up taking control and he'll be forced to succumb to her will." "If you really think that will work, I agree with it." You said with a sigh; a bit miffed you'll make your old body look better.
Eventually, your son does return, clearly having enjoyed working out with your....his body. "Hey, mom," he says, waltzing into the house. "I never knew this body was so athletic for its age, it's amazing!" He gloats; you can't figure out if that was intentional or not. "Good to see you're acquainted with the new you; acceptance and self confidence is always a good thing." You encourage, like a parent would. "I know," he says, taking off his tank top and letting his large breasts jiggle in their sports bra. "Though, I can say the same thing to you. You don't seem so against being like that anymore." 'Oh, you have no idea, kid!' You devilishly think.
As your son wipes the sweat from his face, you take the opportunity to zap him with the sizing remote, having practiced using it while he was still out. Immediately, he felt strange; the sports bra containing his breasts began to feel tight. The lovely orbs soon began to burst out of the top, indicating them increasing in size. "What the!" He shouts, as they ripped the sports bra completely as they increased to the selected size. His breasts were now an HH at least, yet still managed to look youthful and didn't sag too much. Angry, you then zapped his ass, causing it to plump up a bit more, going up half a size; in response, he shouted and rubbed his larger backside.
As expected, your son dropped to his knees and began messing with the vibrators in his panties. "Aaaah, this body feels so good!" He moaned in desperation. "I can't stop doing this!" His fingers began rubbing his clit and massaging his huge mammaries; the sight made you smile with satisfaction. "This is what you get for being a freak in the first place!" You shout at him. Inside his mind, your son hears a feminine shout, "Oh god, this is amazing! I've wanted this for so long; just keep doing this!"
