Ellen can wait

It occurs to you that you even though you haven't had sex with Ellen in a while, you haven't had sex with anyone else in a much longer while. And you've never had sex with red-headed teenager in pigtails. Ellen wasn't going anywhere.

You unpause your new sister in law.

Wanda's pale skin flushes, thinking you just walked in on her masturbating.

"Bill!" She exclaims. "I was just...just... You're naked!"

"So are you, Wanda," you counter with a shrug.

"Well , yeah, but, um...does Ellen know you're in here?" She asks.

"Not exactly," you admit. "But I can handle her if she has a problem with it."

"Yeah right!" Wanda says."She'll rip you a new one!"

Then she dropped the blanket, revealing her tits.

"Not that I couldn't make it totally worth it to you," she said with a devilish smile.

"Oh, you're going to, Wanda," you assure her,

She frowns prettily.

"Hey, I'm not saying I'm not open to being seduced here, Bill," she said. "But you need to put some effort into it if you expect me to betray my sister Ellen. I'm not just some slut who will fuck any naked guy who walks into her bedroom."

"Yes you are," you say, pointing the device at her, curious how it works when the subject isn't paused.

Wanda looks like she's about to start a rant about you having called her a slut, but when the blue dot hits her forehead, her eyes go wide and glassy and her jaw goes slack.

"You are a slut, Wanda," you speak into the device.

"I am a slut," she repeats in a dreamy, helpless voice that makes your cock twitch.

"You're going to let me fuck you in any way I want and you're going to love it," you say.

"I'm going to let you fuck me in any way you want and I'm going to love it," the entranced woman agrees.

You turn off the reprogramming function and set the device on Wanda's dresser as the redhead blinks back into awareness.

"Face down, ass up, Wanda!" You command.

"Face down, ass up!" She agrees and complies, showing you her posterior and biting down on her pillow.

You grin and hop onto the bed, slapping the old woman's young ass that, as you had told her, belongs to you. You press the head of your cock against her pink labia and she gurgles into the pillow.

You push in. She's tight but wet and she presses back in your direction, very enthusiastic about being penetrated. You grab hold of her hips and thrust home. Wanda squeals. You start to pump. She starts to jibber. You have arrived in Pound Town. Hell, you're the Goddamned Mayor of Pound Town.

You're fucking your mother in law that you've transformed into a 19 year old slut. It's surreal. You can't help glancing around the room and reminding yourself that this is really happening. All of the old woman's stuff is there in the room. Hell, it even still has that 'old lady' smell, though other smells are starting to compete. Young Wanda has a very potent pussy.

A demonic grin invades your face. You reach forward and grab one of Wanda's pigtails and pull, bringing her face up off the pillow and letting you grind even deeper into her. With your other hand, you slap her ass.

"Tell me you're a whore, Wanda!" You demand, then smack again. "Tell me you're a whore!"

"Oh god! Oh god!" She pants. "I'm a whore! I'm a whore!"

"Do you want my spunk, whore?" You ask. "Should I fill you up with jizz?"

"YES!" She screams. "YES! I LOVE IT! I LOVE IT! DO IT! DO IT!"

You explode. You aren't sure where you came up with so much spunk after having shot your wad on Ellen less than half an hour before. Was the youthening contagious?

You groan and shudder.

"So good... So good..." Wanda moans softly. "Such a slut... Such a whore..."

You stroke your chin and watch the quivering, sweaty, spunk-filled mess you've turned your mother in law into. Wait. Could she get pregnant now? No reason she couldn't. Damn. You do not want to father your wife's little sister as a result of fucking her 'little sister'.

But surely the device could help with that.

"What is that thing, stud?" Wanda asks as she sees you more focused on the device than her freshly-fucked self.

You pause her without explaination and continue scrolling through the body modification section. Fairly deep into the options, there is indeed one called 'Fertility'. You point the device at Wanda and slide it down to zero. Problem solved.

But your search revealed many other options that the device was capable of. You really had been thinking small up until now. You could do so much more than just peel away years. The only question is, whose body will you modify first?
