After 20 minutes of tired walking, Zack finally reaches his famly's home. He sighs deeply while taking out his key, desperately craving for a shower. He's been the whole afternoon totally immersed in his soccer training while preparing for the upcoming matches. But since the changing rooms are undergoing a reform, all the showers are inoperative, so he has no choice than to return home first, all covered in dirt and sweat.
Zack starts turning the key but stops for a moment, frowning. He can hear some muted noises coming from his house, noises that at his point he's more than familiar with.
"Oh crap... not again."
He sighs for a second time, fully turning the key and opening the door to the hall.
Those sounds, which turns out they are a cacofony of feminine moans and masculine grunts, start to fully assault his ears while he steps inside, closing the door behind him while leaving the key aside and taking out his dirty shoes in a routine ritual he has been doing for most of his 14 year long life.
He advances a few steps until he's right at the entrance of the living room, looking inside with a very conflicted expression.
Facing him, his half-Asian bombshell of a mother has her hands over the sofa armrest, using it as support while she is getting vigorously smashed from behind by none other than his dad. Of course, they are both butt-naked, and Zack can't help but gulp down while peeking at his mom's G-cup breasts violently bouncing in all directions. Her normally gentle face, now partially covered by her black mane, is making an expression of pure ecstacy that tells Zack she is 'really' enjoying this.
Zack then looks at his dad, his eyebrows furrowing even further. He quickly glosses over his pounding hips and hairy chest, with decently toned shoulders and long arms that end up right where his hands are firmly grapping his whimpering wife's ass. Zack then looks at his face. Just like his mother, his dad also seems to be having a great time, his panting mouth wide open and light brown hair held back in place by a pink diadem with shiny fake jewels that looks completely out of place over his powerful adult frame.
"Ugh..." Zack cusses after noticing that satisfied, rather smug expression on his dad's face, an expression that his agreeable softie of a father would never make.
That is not Zack's dad.
That is Zack's little sister, Molly. She has possessed his dad and taken control of his body... again.
"Ah! Zack's home!" His 'dad' stops pounding his mother for a moment, his face contorting in surprise, eyes wide and voice louder than necessary, showing how it's actually Zack's annoying little sister controlling his body. "Hi Zack!!" he/she greets while shaking both his large hands in a very childish manner.
"H... Hi..." Zack responds with a shy hand gesture.
"Oh, hello sweetie!" His mother greets while brushing her hair away from her sweaty face, voice still panting. "How was the training?"
"Uh... It was okay, I guess..." Zack responds sheepishly, feeling very uncomfortable in this situation which by now has turned to be quite common.
"I'm glad to hear that, honey. However, we need to have a talk you and me, so go take a shower and wait for- AAahh!!" She suddenly moans when Molly renews her thrusts without a warning, clearly using her dad's body as she pleases. "Molly!! I'm talking to your brother, so can you stop for a momeeEEEEEEeeeehhh...!!"
In response, his father's face starts pouting in a way that perfectly resembles Zack's 9 year old sister every time she is being stubborn.
"But mooooooom! I'm about to finish! Can't you talk later?!" She complains in that off-putting masculine voice that doesn't belong to her, without stopping those violent thrusts even for a moment.
"Aaahh! Hiiingh, Oooohhh! I... I guess it can't be helped!" Maddie, Zack's mom, concedes, allowing her daughter to keep pounding her with her husband's burly dick.
"Hehehehe! Thanks, mommy!" Molly says gleefully, putting yet another smug expression on Jeffrey's, her father's face. "Dad's peepee feels so good that I'm going to go super-mega faster! In three! Two! One...! POOM!!"
Molly suddenly leans forward, hughs her mom's waist using her father's long arms... and thrusts his hips with all her might.
"NGAAAaaahhhhhh!!!"
"POM!! POM!! POM!! POM!! Get that, mom!!"
Zack's father is a very well-endowed man despite his gentle nature, his extra-thick 9 inch tool inspiring nothing but respect in women and men alike. And watching how his brat of a sister has been lately treating it like it belongs to her has been a constant source of frustration for Zack.
The boy clenches his fist, unable to keep watching his admired father's body being used like that without saying anything.
"M-Molly! Can't you tone it down, please?! Dad's body is not one of your toys!" He exclaims, trying to sound mature and confident, like the big brother he is supposed to be.
But Molly just responds by sticking his father's tongue at him in a bratty manner.
"I don't want to!" She says, making his father's deep voice sound unjustly childish and annoying. "I like daddy's body, and he gave me his permission!"
Against those words, Zack can do nothing but look down.
That's what frustrates him the most: knowing that his father is okay with it.
"I... Uhng... I-It's okay, dear!" Maddie says to Zack, clearly struggling to contain her moans. "J-Just go and wash yOh! Y-Yourself!"
"...Yes mom."
Zack then turns away and starts walking up the stairs. And by the moment he reaches the bathroom, the entire house echoes with the loud cry of his mom cumming.
Zack's family... is far from normal. And the sole reason for that comes from his mother's side. It turns out she descends from an evolving line of humans with a special bloodline that gives them the power of possessing other people's bodies.
That frightening power seemingly appear at random within the family, which means that not every member gets to awaken it, and that the degree of power varies from individual to individual.
Zack's mom, Maddie, has it. Zack, however, still hasn't manifested any, a fact that has been a thorn to his side ever since his little sister awakened her power at the age of 8.
Zack takes out his sweaty sports clothes and quickly enters the shower, washing his body while remembering his sister's actions during the last year. She'd always been quite the brat, acting smug and spoiled, knowing herself to be her 'daddy's little girl'. But she still behaved properly when she had to.
However, after she awakened her bloodline, she's been out of control, abusing her powers in ways that would make full fledged adults blush. She clearly still respects Zack as her big brother, but she seldom listens to him anymore. It has come to a point where Zack even fears having an argument with Molly, knowing her annoying habit of just jumping inside his body without consent and taking control whenever she can't have her way. And she keeps doing it even though mom always scolds her! Saying that such action is a violation of her brother's freedom and privacy.
However, Molly's favourite body to jump in is by far that of Jeffrey, their father. They have always been very close due to him spoiling her rotten since she was born. Also, Molly seems to love being tall and strong, so she spends a lot of time inside his body, which he doesn't seem to mind. Sometimes, she even uses him for her childish Disney princess cosplays, enjoying the game of dressing his large body and putting make-up only to leave his body afterwards and laugh at his reaction.
Despite her bad behaviour and all the times he gets frustrated because of her, Zack still loves his little sister. But he can't help wanting to get away from her every time he has the opportunity.
However, deep inside, Zack knows that his little sister wouldn't have turned like this if his family's dynamics weren't already quite... 'abormal' to begin with.
.....................
After he is done with the shower, Zack dries his lean body and looks at the mirror while using the hair dryer to finish the work, his brown wavy hair dancing under the hot air jet. He's a teenager of average height, slim torso and a slightly androginous face that reminds him of his mother's. His only defining factor are that pair of well-toned thighs from half a life of playing soccer.
After he finishes drying up, Zack dresses up with a red t-shirt and short pants and steps out from the bathroom.
"Oh..." He mutters, noticing his mom approaching him through the hallway. She is by now fully dressed, though her hair is still quite disheveled. And is being followed by another, shorter figure. A naked little girl of long brown hair.
"Hey bro!" Molly beams at him, her bratty face displaying a cheeky smile. "Did you like the show?! Daddy enjoyed it a lot. And mommy too!" She turns to Zack's mom "Right, mommy?"
"Yes, honey, mommy really enjoyed it." Maddie responds in a calm manner while patting her daughter's head in her typical motherly way, making it hard to believe she is the same woman who was moaning like crazy while being pounded just 20 minutes ago.
Zack sighs in response, massaging his temples.
"Why are you naked?" He asks Molly.
"Huh? I just came out of daddy's body" She says, like that was a valid explanation. "Now stop staring, you pervert brother"
I clench my fists, frowning at the injustice of being called pervert by none other than 'her'.
"I'm not staring."
"Yes, you are, you're looking at my nipples."
"I'm not!"
"Now, now, stop you two." Mom's relaxed voice interrupts the siblings argument. "Your brother is right, Molly. You should put on your pajama, clean your teeth and go to bed. It's getting late and good girls have to sleep"
"Yes, mommy!" She says. Apparently, mom is the only person who can effectively control Molly.
Molly walks past Zack, not forgetting to stop for a moment to stick out her tongue at him, exactly like she did with their father's body 20 minutes ago.
"Well now" says Maddie when they're finally alone "Let's talk in your room"
Zack gulps down and does as his mom says, both entering his room. And once inside, Maddie immediately crosses her arms, making her extremely plump breasts bulge out like a gigantic pair of jellies.
She used to be a model in the past. Now, at 38 years of age, after maternity has added extra curves to that already sexy body, she has straight up turned into every man's wet dream. Zack really has a hard time keeping his teenage hormones in control whenever he sees her body in full display. Which, thanks to his problematic sister, happens quite a lot.
However, this siuation is no joke. Seeing her face, Zack can clearly tell that he's screwed.
"You still haven't taken out the garbage, and you clearly forgot to add your sister's clothes to the laundry."
Zack lowers his head under his mother's severe gaze. "Ugh..."
"Not to mention, the car is still dirty, your room is a mess, and the lawn's grass is almost reaching my knees."
She closes distance, hands over her wide hips.
"I know you are busy with your studies and soccer practice. And I know your list of chores isn't small. But you accepted to do the work in exchange for your weekly allowance." She leans forward "We had a verbal agreement. Didn't we?"
"Y... Yes. We did." Zack answers sheepishly.
"I'm very disappointed in you, young man. If you can't even take care of those little tasks after giving me your word, how can your mother trust you in the future?"
"I... I'm sorry."
Maddie sighs deeply, hand over forehead.
"I'm also sorry, dear, but this time I can't let you go unpunished. You have to learn the price of responsability."
"...Mom..."
"You know we have to do it, right? Now Zack, take off your clothes."
"But."
"No buts. Now go and take them out." She insists while also undressing. Zack looks at his mother's body, eyes wide open. She really has no qualms on getting fully naked in front of her teenage son, even going to the point of showing her exposed pussy, with her husband's semen still gushing out from it.
Once she is fully naked, she stands in front of Zack, her swollen nipples only a feet away from her son's face.
"What are you waiting for? All clothes out. Now."
"C-Can I atleast keep the boxers on?" Zack asks with trembling voice, not wanting to get naked in front of his 'imposing' mother.
"You know it won't matter in a while, right?" She asks, eyebrow raised.
"Still..."
"Haahhh... Have it your way." She concedes, sighing "Now, sit on the bed."
Zack obeys, putting his clenched fists over his naked thighs. And his mother gets on the bed, right behind him.
"Don't worry, sweetie" Maddie says while patting his head, voice reasuring "You know you're mommy's favourite boy, right?"
Zack slowly nods, lips tight.
"And you know that mommy always treats your body very well, right?"
Zack nods again, a bit quicker.
"Heheh. Of course you do. Now relax your back. It will be over before you know it."
And right after saying that, Maddie's hands start sinking into Zack's shoulderblades, making him feel a very familiar pressure all over his spine.
"Gaah!!"
Her hands immediately disappear into Zack's body, arms going next. And, after 10 seconds, the chest follows, Maddie's plump breasts physically sinking into her son's teenage body.
"I'm always amazed at how quick Molly manages to do this" She casually comments while slowly leaning forward "Almost like she is just jumping in an out at pleasure. She trully is a gifted girl after all."
Zack shuts his eyes tightly while feeling the warmth of her mother's substance entering his flesh. The only times his mother's voice doesn't sound as reasuring is when she is talking about his sister's monstruous talent. He can't help the spark of jealousy, wishing she said nothing instead.
After 2 minutes of action, Maddie's body has completely been absorbed into Zack's. Then, all of a sudden, his lean body starts trembling violently due to the action of is mom taking control of his nervous system. His eyes quickly lose focus and he falls on his back.
"Aaaaahhhhhh..." He moans in a rather flat voice, drool coming out his mouth.
But then, it suddenly stops, eyes regaining focus, pupils expanding slightly.
Zack blinks twice and slowly sits back up. However he didn't mean to do that. It wasn't him who told his body to move, and surely he isn't the one who is making his face smile or the one who is massaging his thighs with his own hands.
"Gosh, sweetie, your legs are aching." Zack's voice resonates in his own ears. "You shouldn't go too hard in your soccer practice. I can't have my boy get injured."
His body then stands up on the floor while stretching his slender arms.
"Still, it feels really good to be in your body. Almost like I'm finally having a proper rest. My shoulders were killing me..."
As if to showcase her point, Maddie does a gesture in front of her son's chest, like she is holding a pair of imaginary breasts. She can't hear her son after he lost control of his body. But she knows he can hear her, and feel every single thing his possessed body feels just as much as her.
"Now, I reckon you haven't had supper yet, right? Now we can't have that, dear. You need to grow big and strong, like your father." She says the last word with a slightly lewd tone, probably remembering the 'session' she just had with him... Or with his possessed body.
After saying that, Zack's body steps out of his room still dressed only with his boxers.
"At least put some extra clothes on!" Zack yells in his mind. However, his mom can't hear him in this state. Zack knows she could make it so they could mentally communicate. But, for some reason, she doesn't do so. Maybe as a part of his punishment.
After going down the stairs, Zack's body enters the livingroom. And he is surprised to see his father still completely naked, his 6'4'' tall body sprawled over the sofa, legs open and his fat dick resting over the fabric, still covered in semen and his wife's vaginal fluids. He looks rather tired.
"Hello dear! Are you faring well?"
"...Huh?" He mutters, raising his head. "Maddie. Is it you?"
"Heh heh. Of course you would recognize me immediately." Maddie says in her son's voice, while sitting right next to her husband, legs touching each other.
"How could I not?" Jeffrey says as in a matter-of-fact. But then, his loving tone changes to a more severe one. "How was he?"
Maddie sighs, straightening her son's back. "I think he is learning his lesson. However, I have to make sure he truly gets it this time. He can't keep being this messy when he is almost 15"
"I see." Her husband simply nods.
"So I will have to restrict his freedom for a while. How long will it be? I will decide it on the march."
"I understand, honey." Jeffrey then puts a big hand over his son's shoulder "But don't be too hard on yourself. You don't need take care of every single thing related to Zack. I can help too, you know?"
Maddie takes her husband hand from Zack's shoulder and kisses it, unaware that her sudden and loving action is making her possessed son extremely uncomfortable.
"Of course I know that, dear" Zack's throat vibrates in a sensual tone "But this is something I want to do by myself, as his mother."
She pauses for a moment.
"Also, this is a great opportunity for me to take notes of my boy's growth!" She suddenly exclaims, flexing Zack's thin biceps.
Jeffrey simply laughs in agreement, flexing his own, thick bickeps in response.
"Show off!" Maddie says, also laughing "Boys sure are hopeless, always turning every single opportunity into a dick measuring contest!" She suddenly looks down at Zack's tight boxers "Speaking of which..."
"What are you thinking, dear?" Jeffrey asks, smilling.
"Exactly what you think I'm thinking."
"Is Zack okay with that?"
Zack wished he could shake his head and yell that he is NOT okay with that. But he can only stare, unable to challenge his mom's control over his body.
Maddie just chuckles. "I've had him in my womb or 9 months. He has no right to deny some of my innocent motherly curiosity"
Jeffrey chuckles once again "I wonder..."
