"Have you decided, Billy?" Jenna asked with that twinkle in her eye, that all-knowing smirk that stated she knew what his answer would be.

William 'Billy' Basker had always been madly in love with Jenna Foster ever since he first saw her in kindergarten. Jenna was one of the daughters of a trillionaire businessman, one so ridiculously wealthy he could afford for her to have gene editing to give her the perfect appearance and intelligence. As the pair grew older, this chasm of power, intelligence, wealth, and looks grew wider between the pair.

Billy entered his early thirties as a balding, skinny man. Short and sickly, recently fired from his job, a lifespan of just ten more years if he was lucky.

"It's... isn't it a bit much? Like, what would your husband think? James doesn't even like me."

"He's on board with it. He thinks it's cute," Jenna lied.

At thirty-three, she looked like she was an eighteen-year-old supermodel. Slim waist, large, firm, natural breasts that were extremely perky, and a toned ass. She had the most beautiful silky, shoulder-length black hair cascading around her perfect face with full lips and bright green eyes.

"He fired me," Billy pointed out. James Bennett was her husband, the one who wooed her away from him.... Well, Billy was never in contention for being her boyfriend, but still, it stung, having his rival be his boss, browbeat him for years, and finally fire him.

"This is mine and Daddy's decision, not his," Jenna rolled her eyes. "I know he's a bit of a dick, and you always warned me about him. I'm sorry I didn't always listen to you, but he isn't going to be involved much with you, I promise."

His heart fluttered a little. "Are you two having problems?" Billy asked softly.

"Daddy has run out of patience with him," Jenna sighed. "James tanked the Europa proposal, which he blamed you for, even though he had demoted you and made you redundant. That was the final straw for him."

"So did Mr. Foster fire him?"

"Oh no," Jenna shook her head. "We still have three years remaining in our marriage clause, so I can't divorce him till then without losing a significant chunk of our assets. He's still around because of that, though Daddy has made sure he won't be around after."

"Okay..." Billy gulped. "But that means he still is going to be..."

"Your daddy? Yes, he would," Jenna sighed. "But only for three years. I will be the one who is legally adopting you in my name. You will be William Jenna Foster, not William James-Jenna Bennet. Daddy will be footing the bill; he's going to be responsible for everything."

"But like...to be your kid?" Billy blushed.

Jenna had called him out of the blue yesterday and practically announced to Billy that she was going to be adopting him legally.

The ban on unlicensed biological birth was in effect just five years ago to prevent generations like Billy, who had horrible genetics. It led to new laws governing physical age regression, and "adopting" those adults who had no future was becoming a thing for the wealthy.

"You won't be physically regressed to a toddler," Jenna laughed. "As cute as you were when you were small…no. Your new body will be very much an adult, though smaller in stature...though you are already small, so like...just a few inches off of your current body. You will have multiple sessions over the next thirty years to improve you, so by the end of it, I expect you'll be closer to how Daddy or James looks now."

"And then I won't be considered a child anymore?" Billy questioned.

"You aren't a 'child,' child. It's not like you will be seen as one," Jenna rolled her eyes. "You can still go to work and study, but no driving or traveling alone. There may be... restrictions on sex depending on the conditions. The contract just gives me complete control over your life to fix your genetics in exchange for being able to cuddle and kiss you like my widdle baby," she teased, pinching his cheeks.

Billy turned pink at the physical contact, not expecting it, which Jenna noticed.

"But yes. It'll be a thirty-year contract; once it's done, I get to move to have a natural child of my own. You can continue to be either William Jenna Foster or go back to Billy Basker, but with a new body that'll live on for at least four hundred years," Jenna laid everything out.

"And quit acting like you have any choice in the matter. Your illness is doubling; you kept your condition a secret from us for ten years. Daddy would've sponsored you anyway if he had known."

"I didn't want to worry you," Billy said sheepishly. He had cut off contact with Jenna for close to a year now after her wedding, not taking her calls and brushing her off.

"Don't think you are going to get away with it," Jenna smirked. "Once you are my boy, Mommy's going to tan that tight little butt of yours for making me worry for a year."

"What?" Billy was taken aback by her words.

"In my family, boys and girls get spanked, Billy—until they are of age." Jenna's eyes glinted. "You know how I was spanked by Mommy and Daddy."

"Yeah, but, I'm an adult. I'll be an adult," Billy replied breathlessly. He hadn't considered that! He was mostly thinking this was an act of pity on her part, and there would be no physical intimacy other than her relentless teasing of him.

...but spankings? Spanked by Jenna, his Jenna? He had always fantasized about that, about her owning him and...

"Oh, you will be my boy, so I get to decide on everything, Billy. You sorely needed structure and discipline in your life, so rest assured I will take you regularly over my knee and spank you like a naughty little boy whenever you deserve it."

Her words just made him hard. Billy gulped, giving a small nod. "Alright, Mommy," he blushed brightly.

"Wait... you like that, don't you?" Jenna realized, her smirk growing wider. Her eyes flicked down to his crotch, and sure enough, the proof was tented up under her pants.

"I see." She got up. "Marianna Clinic, tomorrow afternoon, 3 PM. A car will be sent to take you over at two. You will be under observation for a week, and I'll pick you up next Wednesday."

...

The procedure went smoothly, all things considered. Not that Billy remembered any of it, as he was medically put in a coma while his body changed. He didn't know it, but Jenna made a last-minute request to change his buttocks, give him two extra inches of fast-healing fat and muscle, and make his ass more round and tight. The lab technician smiled at the request, knowing what it was for.

"Are you sure it's not too big?" Billy asked, squeezing his ass, oblivious to all of it. He was standing in front of a full-length mirror to take in his new body. He wasn't...overly impressed. He still didn't have any of the definition and muscles the other perfectly gene-edited men had, and he still was short. The only saving grace was his nice big cock, which the nursing staff couldn't keep their eyes off of.

"It can never be too big," one of the blonde nurses winked as he blushed. Billy had never been the object of a woman's attention, so he didn't know how to react, though his cock twitched, still at full mast.

"Sorry," he tried to cover himself up.

"Oh, don't apologize! You should be checking for any defects. Mrs. Foster-Bennett will be coming to pick you up momentarily, so once you are done, you can get dressed and be out of here. I'm sure your new mommy and daddy are dying to meet their new boy!"

Her words took Billy out of his daydreams. Of course. Jenna was still married to James; she was still Mrs. Foster-Bennett. He still had to navigate around that oaf.

"When will she be coming?" He asked urgently.

"She's downstairs filling out your forms. You can go to her now if you'd like; we are done here."

Billy quickly dressed up in the T-shirt and pants set out for him, heading down to the waiting area. He looked around and sighed in relief at only seeing Jenna there. She looked extra pretty today, her hair elegantly styled and wearing a black knee-length dress that complemented her ample curves.

"There you are!" She beamed with pride. "You look so adorable!"

"Thank you," Billy blushed as he approached. Jenna had kept a small eye defect for Billy, as she loved his glasses. His hair was back, thick and messy black, with a slim figure with a bit more meat on him, most going to his reinforced rear.

"Let's go, dear. Daddy—well, Grampa wanted to meet you, but he had to go for a meeting, so he couldn't come. We will visit the family tomorrow. My sisters are dying to see you again!" Jenna seemed extremely excited and proud, something that made him feel better about all of this.

"Alright…" Billy smiled weakly, following her. "What about...um…like James?"

"Oh..." Jenna soured as she waited for the car to come. "Well, he's Daddy from now on. My dad is making him clean up the mess he made, so he's going to be busy a lot. He's over at the space station right now, so he won't be back for another six months."

"Okay…" The car approached, and Billy climbed into the car with her.

"What's the matter, bud?" Jenna gently tousled his hair.

"Like...I don't know what his relationship is going to be with me," Billy said softly. "And you...like how our dynamics are at home." He gulped, looking at Jenna. "Like...is he going to be spanking me?"

"Oh!" Jenna realized what he was worried about and let out a laugh. "Well...yes and no," she grinned.

"What does that mean?" Billy asked impatiently.

"Well, he is your legal daddy through his marriage to me, so corporal punishment is his right. But because of his history with you, firing you and all that, there is a no-physical-contact clause in our agreement. If he breaches that and even touches you wrong, it's grounds for immediate divorce, and he's out of our lives."

Billy let out a sigh of relief. "That makes it better," he admitted with a smile.

"But that doesn't mean you're off the hook," Jenna pursed her lips. "He still has authority over you, which means if he wants to see you punished, he can order me to do it. And as long as it's a reasonable instance, I will have to comply."

Billy looked at Jenna, who seemed not too...displeased about this.

"So only you get to spank me then?"

"Mostly me. My sisters, maybe Mother might also like a crack at your butt if you are too cheeky with them," Jenna bopped his nose.

Billy blushed at the thought. He had a small crush on Mrs. Foster when growing up; she was a stunner back then. And still would be, he realized. The rich don't physically age after all. Both her sisters were extremely attractive too, so the prospect of all four women thrashing his ass... Billy's cock began to strain under his pants.

Jenna noticed the reaction immediately. "Oh...and there is one more slight issue," Jenna blushed a little. "Regarding that."

"I'm sorry!" Billy covered his crotch immediately, realizing he was caught. "It's…uh...I'm getting used to my new body."

"One of the conditions Daddy and I agreed with James when I brought up your name for adoption was that I don't have any sexual relationship with you." Jenna explained. "Now what that means is whenever you are in the house, whenever it's just you and me, you will be required to wear a chastity sheath."

"What?" He blushed as she reached for her purse to take out a small condom.

"It's not like a metal cage or anything and is designed to be comfortable. You can still pee, and it's self-cleaning, but it's designed to be active only for me." She reached for his buckles, sliding his undies and pants down as his massive rod jumped into view.

"It's a shame I won't get to see this part much," she hummed, grabbing his cock as she slowly slid the sheath in like a condom. He was sure he was going to cum, but as soon as she put it on, Billy felt a small electric shock. The more he looked at Jenna, the more it got until he was finally flaccid, tears flowing down his face.

"It's only active with me. You should still be able to get hard when thinking about other women." She pulled up his pants and undies as if it was nothing.

And it was nothing, Billy realized. He was her boy now, it was common for mothers to pull down the shorts of their boys to spank their butts or just to inspect them. She had sent him a list of all the rights and duties he had, but Billy just focused on Jenna's words on how she was going to spank him; he didn't even pay attention to the list. He should really read through them soon.

"Are we going to your place with James?" Billy asked her.

"I've moved out of the house with James for the most part. We are going to my apartment," she explained. "James may still drop in from time to time, as he's still my husband, and I do have conjugal obligations with him."

"So you'll be fucking him often?" He blurted out without thinking. Jenna glared at the words.

"Yes, your daddy and I will be having sex when he requests it. It's his right as my spouse, just as it's my right as your mommy to teach you to watch your tongue as soon as we get to the apartment."

"Sorry," he added quickly, looking down on his lap. Excitement and fear soon bubbled up in the pit of his stomach as he watched the city skyline get closer and closer as the car finally got to Jenna's apartment.

"Out. Go to the living room and strip fully naked." Jenna ordered as she got out, taking a cigarette out.

Billy got out, quickly rushing up to the elevator, which took him straight up to her private apartment. It was an extremely posh and elegant space with a mid-twentieth-century design, lots of natural light from full-length windows, neutral-colored furniture, and a big fireplace that kept the inside nice and cozy.

Billy soon began stripping out of his clothes, finally able to inspect his cock. The chastity sheath was bright pink, and he realized it had Jenna's name on it! He touched his cock, slowly stroking it, and was shocked to see it worked just as it normally would. It was so big, especially compared to his body, which was just above five feet tall. He guessed it was around eight inches thick, and the material made of the sleek material sheath made stroking himself feel more and more aroused. This felt incredible!

"What are you doing?" Jenna raised her brow as she entered the room.

"Oh!" He gasped, taking his hand off the cock as the light shocks got him to grunt in discomfort, the cock going back into a limp yet surprisingly big state. "I was testing...it gets hard. Can I still cum with this on?" He asked her.

"Boys..." Jenna rolled her eyes. "We will deal with that later, Billy. Right now I want you to come stand in front of the armless chair in the middle with your hands on top of your head."

She watched him quickly rush into position in front of the spanking chair. She was surprised at the speed he moved with before remembering how much of a pet he was of hers. Of course, he wanted to please her. Jenna's eyes drifted over to his special reinforced ass, designed for her to thrash to her heart's content.

She began to get excited!

"Do you know why you are about to be spanked, Billy Jenna Foster?" She used his new full name, circling him like a hawk as she went and grabbed his left ass cheek.

"I...uh...asked if James still does stuff to you," he replied, using words that might be more palatable for her, shivering at the contact. He had so desperately wanted her to touch him like this for decades! The cock sheath prevented him from getting hard, but he could still feel his member inside it, slowly leaking.

"You asked if your daddy still fucks your mommy." Her palm smacked his ass to a loud yelp. Jenna marveled at how his flesh bounced on impact. Soft and smooth like butter, with her palm print forming.

"In this household, you will obey my rules as a good little boy would. Because as of this moment, that's who you are. Not thirty-three, not a college graduate, not the guy living in that tiny hole of an apartment in West Vauxhall. You are the boy of Jenna Erik Foster."

"I thought you were Mrs. James Foster-Bennett," Billy asked cheekily, earning another two spanks.

"Don't get cute with me, Billy," Jenna smiled, walking in front of him to savor his gasp as she had stripped down to her bra and panties. "There is a very fine line on how you and I can be together, so I expect you to toe that line."

"Be together?" Billy asked. She grinned, leaning down to kiss him on his lips. Not a deep one, just to get her point across.

"My daddy wants to make sure I end up with someone who can take care of me, and that has always been you." She sat down on the chair, holding his hands. "I waited for you to pull yourself together for over fifteen years before marrying James...and with him being a dumb turd, now I can't wait any longer. As you won't straighten yourself up, I'll be doing it for you." She sat down on the chair and quickly yanked him across her knee, softly rubbing his ass.

"You knew?" He gasped softly over her lap.

"That you were hopelessly in love with me and didn't have the balls to say it?" Jenna spanked him hard, holding him tightly against herself as she concentrated on smacking his ass over and over. "You lack initiative and direction, little boy, so it's Mommy's job to give it to you!"

"Oww owww! I'm sorry!" He gasped. "I should've told you!"

"Yeah, and now it's too late, and I'm married to a jealous jackass who doesn't want your dick to be hard around me!" Jenna growled, continuing to spank for another two minutes before reaching to the nearby table to grab a hairbrush.

"Fortunately, James said nothing about your ass, Billy." She rubbed and squeezed his cheeks, prying his crack open as she looked in between, his tight little rosebud winking in her direction. "James is too macho to think I wouldn't enjoy this...but you like it, don't you? You like your mommy completely owning this ass?"

"Yes, ma'am," he replied hoarsely. The cage was dripping his precum on her thighs; he felt completely raw, and yet, this felt like the best day of his life. It was the best day of his life.

"Good. Mommy's going to spank you with my hairbrush good and hard. James is my husband for three more years, so you will bear him whenever he's around, and you will be polite with him. You will grin and nod and be a good boy in his presence, if you don't... I'm going to make this spanking feel like a picnic."

Jenna started to spank, unleashing loud, harsh blows to tenderize his soft yet firm ass. She spanked him relentlessly like a machine, getting wet as his cries grew louder. He started calling her Mommy and begging her to stop by minute eight. In fifteen minutes, his ass was hot to touch, bright red.

"Get up and bend over the sofa," she ordered, going to grab the belt from the floor. "And you will not throw your clothes like a drunk college student from now on, Billy. Mommy will be raising the perfect gentleman for me." She started whipping him with gusto. Aiming to cover every bit of flesh from the top of his ass to the boy's thighs. His cries were music to her ears as she started fingering herself under her panties. Lash after lash, playing with her clit till soon she started cumming over and over.

And as she was done, Jenna walked over, sliding her fingers inside his mouth. "Suck," she commanded to the teary boy, who did so obediently. "It's a shame I can't have you lick me to an orgasm... But there are workarounds," she grinned, scooping him up for a big wet kiss.

"That..." Billy was completely out of this world by that point, caught between heaven and hell. His ass was burning, welted up from the exertions of his sexy fit crush, but his face was pressed into her breasts, the one place he fantasized about above all else. "I love you," he blurted out.

"Fifteen years too late, but I'll take it," Jenna laughed. "Breasts were another part of me James tried to forbid you from, but Mommy's breasts are for little babies, aren't they?" She carried him into her bedroom, taking off her bra. "Now suck." She smiled.

He did, blinking in surprise at the sweet taste as his mouth started slowly filling with creamy milk.

"My milk is part of your treatment. A symbol of my authority over you." She kissed him deeply, Billy realising how sensitive Jenna's was by her moans as he sucked her. He continued to rub and squeeze both breasts, marveling at how firm the pair were and how clean it was. The milk only flowed when he sucked deeply, forceful enough to get her off another couple of times.

"Good boy," she moaned as she cradled him close. "You are where you belong now, Billy. Mommy's gonna raise you to be my perfect husband."
