Jon's older sister Becky poked her head around the door. Her usual look of revulsion at the explicit scene in front of her passed across her face.
"Jon, Zoe, mom says dinner will be ready in five, but she'll keep it warm for you two until you're done."
"Okay, thanks," said Jon. Zoe moaned in pleasure.
As Becky turned to leave, Jon decided to see if his power could change his prudish older sister.
"Becky," said Jon, "you're a slut and love wearing revealing clothing."
Becky turned around, wearing a low-cut, midriff-baring top and miniskirt. "Well, of course. What would make you say such an obvious thing?"
Jon had no idea why he would state the obvious like that. Clearly something more drastic was needed.
"In fact, you are my sex slave, just as Zoe is, and when it's just the three of us you always go naked."
Becky's clothes vanished, exposing the familiar sight of her naked form to Jon and Zoe.
"C'mon, Jon, why are you saying these things? And when will you fuck me?"
Jon was baffled. Clearly something even more drastic was required.
"Becky, Zoe, you know that I never let you go unsatisfied. I mean, whenever I'm fucking one of you, I'm mauling the other's gigantic tits."
Becky was sitting next to Jon, who was fondling her prize-winning-pumpkin-sized breasts as he always did when Zoe rode his cock, her own equally large tits flying about.
Jon counted himself lucky that the women on both his mom's and his dad's side of the family all had large breasts. Clearly the genes had come together just right to give his sisters these fine ones he enjoyed on a regular basis.
Still, he had no idea why he was just saying such obvious things.
Suddenly Zoe screamed in orgasm and, once she came down from it, hopped off his dick. Having two super-hot sex slaves gave Jon incredible stamina, and his erection didn't subside in the slightest as Becky ground her way on and began massaging it with her talented pussy muscles.
While feeling up Zoe's glorious breasts, Jon grew ever more frustrated with the fact that his power just didn't work!
"Becky, Zoe, apart from your desires for sex with me, you are lesbians. You regularly find attractive women and bring them to me so that I can turn them into busty sex slaves like you. They don't live here, though, because I want to have a woman I can fuck in as many houses in the city as possible."
"Well, duh, bro!" exclaimed Zoe. "I mean, you've got most of the high school and a good chunk of Becky's university. What do you want, every fuckable woman our age in the city and their moms too? Maybe next you'll want us to get all the men, too," and at this Zoe shuddered slightly, "before they get frustrated about how you're the only guy in the city whom the women will screw!"
As Jon shot his load into Becky (who obligingly reached orgasm at the same time), he could have screamed in frustration. What was the use of being able to make anything you said come true if you only ever said things that were true?
