It was a calm night at the Smiths house and you know why? Because Roger was not there to make everything a damn madhouse. The grey alien was in an outer space party in which he said that when he came back would only be when the party got tired of him.

And how he would come back? Well...

"Ahhhhhhhh!"

Falling from the sky in a ball of fire and hitting the yard, it was a good thing he was fireproof, or else he would be toast. But the landing still hurt like a bitch.

And that he was as drunk as he could be, so the pain wasn't much for him.

"F-Frigging jackasses. Can't handle the life of the party!" Roger slurred out as he pulled himself out of the crater he made in the backyard, stumbling around the pool so he could get into his home.

Still pretty buzzed. He somehow manages to get inside the kitchen while his legs wobble through the way, and in his stupor, he decides to open the fridge and put one of his bottles of space booze and a weird fancy pink bottle that he doesn't remember being there before.

"Meh, must taste like space strawberries"

He was tempted to drink it again to remember the flavor but he had enough to drink and shut the fridge to save it for later. It wasn't going anywhere so Roger didn't have to worry.

Thanks to all the noise that he ended up making, some of the family members decided to come downstairs to see what all that was about.

"What is going on here?" Francine asked.

"Roger? Ugh I know it was you" Hayley said, and right behind her Jeff.

"Oh, hey Franny! Hey Jeff and Hay Hay! How are you doing?" Roger said with a wave.

Even Klaus was there but he decided to stay silent since most people didn't care about his opinion.

"Do you know what time it is? Did you just arrived now?" Francine asked.

"And making a huge mess no doubt" Hayley said annoyed.

"Oh cmon, we all just want to have a good time. Where are the other ones?" Roger asked not seeing Stan or Steve.

"Steve is sleeping right now and Stan is working late again." Francine filled him in as she crossed her arms. "You should count yourself lucky that Stan isn't here or else he'd get on your case for coming home late again when you know-"

"Yeah yeah, I need a disguise just to go out or else I'll be discovered! B-But I had a g-good excuse this time." Roger slurred as he wobbled before leaning against the fridge.

"And that is?" Jeff asked out of curiosity.

"I was at an alien party, so I didn't need a disguise" Roger said with a lazy hand wave.

"Cool! I wonder what a party with aliens is like" Jeff said.

"It's Fucked up! The good type. But if you all bitches are so in need to get in my case I may give you all something nice to you shut up"

"Something nice? Like what?" Hayley asked as she put a hand in her hip. "Alien booze?"

"No no no, but it's still good!" Roger said as he kept the fact he already had alien alcohol in the fridge.

Or maybe he just forgot already how drunk he is, but he didn't care.

"How about I bring you guys to an adults-only weekend spa resort?"

"A spa weekend? Is this gonna be like that time you invited mom and me to a spa but it was only for two to the Chimdale Spa?" Hayley asked with snide, the memory of that rather stressful weekend still in her mind.

"N-No no no no no! This time is different, it's legit!" Roger said to them.

"I don't know about this Roger, Stan is not much for that kind of thing, since his male ego is so fragile to things he considers to be girl stuff" Francine said.

"I like spas, they make my skin look pretty" Jeff kept going.

"Don't invite him, then, is that simple" Roger said.

"Really? But isn't that uncool? I know Stan is a little much but that shouldn't be a reason to leave him out." Jeff said in defense of his father in law, even if he was an asshole.

"Screw him. I tell you that, if you think is unfair then go ask him if the dude wants to come. You waste spit though"

Though Jeff still felt bad about it, he couldn't help but silently agree with Roger. Just like Francine and Hayley knew, Stan could be stubborn and stupid about the things he likes and dislikes.

"Good to know we are all into this, now let's sleep and have a good time the next day, we can offer him and...well should we bring Steve? He can be such a bummer all the time"

"Eh I think we can leave him here, Steve might like the alone time. Plus he doesn't seem like the spa type but nowhere as bad as dad" Hayley said with a shrug.

"Hell yeah! Even better! Let's just tell Steve where we are going and not Stan so he doesn't annoy us to death saying we should not go. And don't even say it is a bad idea Jeff, I swear to god. Kill my vibe here and I stomp you" Roger said pointing at everyone and not just Jeff.

He was Drunk...

"...Okay, Rog. I won't tell but you better remember this." Jeff said to him, knowing that he was round "blackout drunk" level.

The group would then immediately leave off the next day to start their good time that was surprisingly given by Roger and who the latter even after getting sober was happy with the thought. What about Steve you ask? Poor nerd was left home alone with nothing but his thoughts and his Jerk of a father who still had to come back from whatever he was doing.

"The nerve of them not getting me there, they even got Klaus! I mean wtf?" Steve said while playing games.

It was a calm Saturday afternoon and Steve got home from school a few hours ago. He was met with a note and some premade meals as most of his family left for the spa. So for the next 2 days, it was just going to be him and his father so in short...a boring weekend of no bonding or heavy conversation since he never felt close to his father.

Then the door is suddenly opened and from there Stan comes out looking tired.

"Oof! What a day, I just want to eat something and relax for a while. Francine!" He screams "Can you make me a sandwich?"

"She is not home dad, actually right now there is just you and me in the house" Steve said, not even looking at him.

"What? Where is everyone then?" Stan asks with his arms crossed.

"Roger invited them to go to a Spa for a few days"

"The spa?!" Stan said in quick anger.

"Yeah and they didn't even invite us"

Personally, Steve was a bit insulted by not getting invited since he did like to be pampered from time to time.

"Oh well, that's just great! Who's gonna cook dinner and clean up around here?! You know what happened when Francine became a stand up comic, what if that happens again?!" Stan shouted as he threw his suitcase at the staircase.

"Well dad, has it ever occurred to you that perhaps this is a chance for us to learn how to be more independent of mom? Maybe learn how to make our own food and fondle our clothes ourselves" Steve mentioned...not that he didn't know how to do that already.

"Fold our own clothes? Feed ourselves? Steve, I already did that when your mother was racked with guilt from a murder she didn't do, and that made me appreciate that God did a great thing by making wives! I already have a job as the breadwinner and paying the bills, it's the woman's job to keep the house clean and keep her family fed. The only men who cook for and clean for themselves are gays like Greg across the street." Stan lectured as he walked to the kitchen. "I'm gonna go get a beer while thinking about the lesson I gave you."

Steve took his eyes off the tv to roll them before looking back at his game, of course, his father would remark that. Just shows how far his head is up to his ass and how large his testosterone count is. Basically, he's a modern caveman.

Stan goes to the kitchen muttering to himself "Stupid family, not inviting me to go. I wanted to go to the spa too, they are awesome"

Opening the fridge he looks for anything good eating or drinking but there were no beer cans which he groans, instead there was this weird-looking Pink bottle that he never saw before.

"Huh, what is this?"

Feeling curious about its contents the man decides to open it and takes a small whiff from it, the smell was that of sweet things, and though he wasn't one for that kind of stuff he thought it was perhaps either something of Hayley or Francine.

"Let's see how they feel when I take something from them"

Acting like a petty child Stan takes a swig from it finding the taste to be fruity and but delicious, actually enjoying it for a change the CIA agent ends up downing the whole bottle from its liquid. Feeling refreshed and almost like the fatigue he was feeling was now gone.

The black-haired man tosses the bottle to the trash bin and gives a little cheer for managing to hit it like he was playing basketball, soon going upstairs all energized. But what he did not know is that the bottle had a tiny warning sign printed in good English at the bottom that said. *NOT TO BE CONSUMED BY MALES OF ANY SPECIES*

"Call me when dinner's warm-up, Steve. I'll be in the plate room." Stan said as Steve groaned.

'Stupid commemorative plate collection.' Steve thought bout his father's dumb hobby that caused him trouble when Barry became unretarded.

Who knew behind that lovable idiot was a class spy movie evil genius?

After hours of Stan doing his little projects and whatnot, night had come for them both as he prepared himself to go to sleep, where he was going to lay in relaxation completely unaware that the drink side effects were going to start changing his body into something else.

"Hmmm." He hummed with a smile as he didn't even feel pain as his body changed, shrinking and becoming less muscular as his thoughts changed with his body.

You see the alien concoction was reacting to Stan's dormant genetic codes which were hugely changing his body structure but at the same time it was harmless and he would not feel pain at all or even a wiggle of something wrong...for a while.

Growing...bigger...stretching...tightening...expanding.

"Mmmm, oh yeah" Stan said as his hair grew longer.

The transformation took its sweet time changing every single detail of his characteristics, but then Stan started feeling hot and sweat started forming on his forehead.

'Hmm, man it's so hot today

Opening his eyes Stan decides to get up and walk down the hallway to the bathroom for some reason rather than his bedroom bathroom, he has not realized the changes yet but it was only a matter of time.

Opening the door and getting inside he proceeds to turn on the tap, but then notices something.

"Strange, my hand looks thinner"

His eyes go wide open noticing that his voice was also different, quickly going for the mirror out of instinct he finds out what happened.

"Oh my god...I'm a woman again?"

This was different from that time where he had become a woman by accident when taking the pill that was supposed to help him listen to women. For instance, his voice was changed as well, being now a smooth and seductive voice that would melt away any man who listens to it, and his chest? Damn! That chest was so fucking big that the shirt that was currently holding it together was screaming for mercy.

Heck! Having your dick turned into a pussy didn't even hurt.

If he had to do the math on how big it was it would be a spectacular pair of soft and boisterous H-Cup Tits with a capital H for emphasis.

"T-This can't be real, it must be a dream"

Stan groped his own boobs and felt how elastic and springy they were.

"There is no way these are...oh...ohh my"

Stan started to bite his down lip feeling how a weird sensation filled every corner of the new body rather than the now erect nipples. New thoughts and feelings were filling through the brain, taking more of the original Stan and putting something else in there.

Someone who was feeling in the heat and in need of a good time...he was Stephanie now.

"Mmmm, Stephanie, I like that." She said as she looked over her body and kept examining her breasts.

Looking down at her stretched shirt, Stephanie smiled as her nipples were hard, bright pink, and felt so good right now but she couldn't keep this to herself. No, she needed someone who could appreciate her body in a way she couldn't and there was only one person in the house that could do that for her.

"I wonder if Steve is still up?" She asked herself as she let go of her shirt and exited the bathroom.

(A\N: Try imagining the voice as being Elise from Da Vs)

Going around the corner she sees a dim light coming from the nerd's room, something told the thick woman that he was still up. Probably doing what nerds his age do best at this time of the night.

Stephanie gave a little giggle at the thought of him with his little pecker in his hands but a part of her wanted to see it and what he could do with it.

Peering through the crack on the door, Stephanie watches what Steve is currently doing...and he is pleasuring himself to videos of random women with large breasts...of course.

But the big surprise that made her eyes pop in surprise was his shlong...between his legs, she sported a really big cock of basically eleven inches long and three inches wide, all thick and throbbing.

'Holy fuck, look at the size of that thing'

Stephania felt the heat inside grew intensely, feeling that little speck of sanity and logic fly away.

She licked her lips and cooed silently as she rubbed her legs together, getting wet in record time as she continued to watch Steve and his "third leg."

"Damn this gal named Lois did an awesome job on this Quest for Fur. Look how slutty she is"

Stephanie silently walks inside the room and reaches behind the boy in total stealthy, the nerd being too busy to notice anything wrong.

The more Steve watched, the faster his hands went as he leaned his head back while shutting his eyes but as he did lean his head back, Steve was met with something soft and bouncy cradling his head.

"What the..."

"Enjoying the show huh? How about something more...real?" A soothing voice came to his ear.

Stephanie spins his swivel chair making the boy face a very lustful filled face of hunger that the bombshell of a woman had. Staring down at his met log that laid between his aroused parts.

"Wh-What? How did you-" Steve said before his eyes widened in recognition. "DAD?!"

The reason why Steve recognized that woman as his dad is that he still remembered how he looked that one time when it had been turning into a woman. He wasn't proud of it, but he had to admit it, his dad looked real hot as a woman but that didn't explain the current situation.

"Technically yes but at the same time no. Just call me "Stephanie." She said with a smirk as she dragged her finger up Steve's cock and circled it around the tip.

"AHN!" Steve moaned in surprise and shock "Wait! Wait! What are you doing?" He tries to get away, feeling scared.

"Hey hey hey, it's alright. I thought I'd be a good parent and help you with your little problem." Stephanie said with a smirk.

"That's not the issue! Dad, you have turn into a woman again with...Uhm pretty damn big knockers and...T-That's beside the point"

Steve nervously looked at her huge chest covered only by one button that was going to tip at any moment. What fresh madness was all that?

"Oh, you like them that much, huh?" Stephanie asked as she moved closer, bringing her breasts closer to his line of sight as they swayed. "Well then, how about I give you a better view of them?"

"D-Dad! Please don't, y-your not thinking straight'' Steve gulps.

"Your mouth says one thing but your friend down there says otherwise" Stephanie points.

Gazing down at her son's cock, Stephanie saw it was growing harder and throbbing, some precum was leaking from it, slightly thicker than one might expect.

"Maybe you just need a little bit more incentive" She said ready to remove the last button.

"I-I-Incentive?" Steve related nervously as Stephanie moved a hand to her shirt button.

One swift move and then...

*BAM*

They were all out for him to see, completely naked and bouncy like the perfect pair of smooth H-cup tits they were making Steve look at it like his brain just melted.

"Do you like what you see, sweetie?" She asked him with a smile as she leaned forward to his face.

"O...Oh god" Steve gulps.

"C'mon...you know you want to touch them, just give it a go sugar" Stephanie said with a seductress's voice.

Steve's body moved on its own as his hands moved from his lap and towards Stephanie's large, sexy breasts.

'Damn it, I can't...fight it'

"Ahn!" Stephanie moans feeling her boobs being grabbed.

"Whoa...so soft, and smooth," Steve said slowly.

They were like velvet in his hands and so addictive to feel! He couldn't stop feeling them up, they just felt so amazing in his hands!

"How do you like my breasts Steve? Are they the best you ever saw and also the very best you ever touched?"

"Y-Y-Yeah. T-They are pretty awesome." Steve said as he continued to grope the H-cups before grazing his thumb over the nipples.

"OHNN!~" Stephanie let out a moan way louder this time, letting him know how good it felt.

Her legs were growing weak, so she decided to have a seat. The seat being Steve's lap, with his hands still on her breasts and his cock sandwiched between her ass.

"OH GOD!"

That was so sudden that Steve moaned loudly the first thing that came to mind, first he touched boobs now? He felt huge ass cheeks between his dick.

"This is such a comfy chair, I bet I'm not too heavy for you sugar"

Stephanie then began to grind against his cock as Steve was pulled in between her large breasts! It was almost suffocating but he had enough air to continue to feel up her large breasts and even take a risk by pinching her nipples a bit.

"Ahhhhh shit, this feels so wrong but good too" He said as his cock hardens more "I want to bury my face onto your chest"

"Why ask for permission? go ahead and do it stud"

Wrapping her legs around his waist and her arms around his head, Stephanie pulled Steve deeper into her embrace with his head not firmly in between her large breasts. Not being able to complain or bothering to resist anymore, Steve began to motorboat inside her chest.

'Oh god! Yes! Hmmm, boobs, boobs, boobs! Her boobs are amazing. Sorry mom but your son is about to have the weirdest fun of his life' Steve thought.

''Did I convince you to embrace this new path now Steve? Say yes and I make it worth your while"

To make him give in to her offer more, Stephanie bounced on his lap a bit as his cock ground between her cheeks some more.

"Yes! Yes! Mother of God, yes!" Steve said as he looked out to her face, blushing and aroused!

Hearing that Stephanie grins before standing up from his lap and staying right in front of the geek boy. Then within a second, she was already on her knees, staring at his nicely big donk.

"You know what I'm going to do now Steve?" She asked, licking her lips.

Feeling his excitement going up, Steve nodded quickly as Stephanie moved closer to his cock.

Slowly raising her hand the big-breasted woman stroked his throbbing erection, surprised at its size and seemingly manly power that came out of it.

"HMMM~Oh yeah this is going to do just fine"

Steve watched as the sexy woman that used to be his dad, now nothing more than a bombshell leaned in close, fingers curled around the base of his cock, before it started. Stephanie opens her mouth and begins engulfing his entire member in her mouth, sliding her lips along with the meat log with desire, flickering her tongue around the sensitive shaft.

"Ooooooo!" Steve moaned as he leaned back in his chair, gripping the armrest with all his might as he bit his lip.

Stephanie was a hungry bitch so while she was bobbing her head up and down sucking his cock, she would use her free hands to attack his member with her boobs giving a titfuck\blowjob combo.

"Oooh! Fuck! Oh, fuck! T-This feels so fucking good. Oh, damn it! This is so wrong" Steve grunted in bliss.

The softness from those bazongas was unreal, it was like filling a water balloon with water, but somehow bouncier.

'God or satan, what heavenly abomination have you given me?!' Steve thought as he moved his right hand to her head, kneading into her hair as she kept sucking and massaging him.

The nerd decided, if he was going to do this, might as well take advantage of it and have all the fun he could before regretting it later.

With that he grabbed the woman's head, getting a handful of hair too before jamming deeper on his cock in a back and forth fashion. It was like Stephanie's lips were locked on his pumping dick

"YEAH! AHHH YEAH! Do you like this? You horny whore, coming at my room acting all slutty.

Whenever he would almost pull his member from Stephanie's mouth he saw her running her tongue around the tip of his dick hungrily, before pumping his hips hard until his pubic hair was rammed against her eager mouth.

'SO GOOD! THE TASTE! THE MUSK!' Stephanie thought as she took a deep breath through her nose every time she hit his crotch, driving her mind wild and making her pot wet.

Steve knew that his orgasm was coming, the body stiffed and the pumping reached a pace that made him look like a dog in heat. The grip on her hair was tightened and used that sexy bimbo mouth like a fuck doll

"Oh yeah oh god take it you little...OH GOD YES...YEAHHHHHH!" Steve's tongue was hanging.

Stephanie's new body and found lust were big but even she wasn't prepared for the volume of cum that was suddenly shot into her mouth. Steve's hips bucked as his faucet pumped continuously potent sperm, forcing the bitch to swallow as much as he wanted her to.

Such an eager throat that wanted the copious amount would not dare let any of it fall, and so worked at it with all it could.

When Steve pulled the dick away from her mouth, somewhat limper now, cum dribbled from her mouth as a pool of fluids formed under her legs due to the excitement.

"Hah, hah, hah." Steve breathed heavily as Stephanie quickly swallowed the remainder in her mouth before cleaning off her legs.

But instead of using her fingers to gather up the cum that dropped on her legs, Stephanie showed Steve how flexible she was and stretched her leg up to lick herself clean like a cat.

"FUCK! Stop being so sexy damn it!" He screamed.

Stephanie thought this would be a possible reaction and smirked at his yelling as she continued to show off her limber body like a professional gymnast.

''You're the only one having this show stuff, your sad cause mommy didn't bring you to the spa? I am still here right?" It smirked in smugness.

"Well...yeah. B-B-But..." Steve said before Stephanie stretched her leg to close his lips with her foot.

"Shhh. It's alright, you don't need to deny it." She said with a smirk as she cleaned the last of Steve's first load.

Her body burned hot like wildfire, all this teasing was enough, Stephanie wanted his huge phallus that still remained hard inside of her once and for all.

"And I think we both know it's time to stop playing around and get to the good stuff" Stephanie said as she stood up from the floor.

Steve watched as she went to his bed. Slowly and sexily as her back is on the sheer and legs spread.

"Don't keep me waiting, sweetie" Stephanie said with a wink while rubbing one of her nipples.

'I am really doing this? There is going back if I do so" Steve pondered.

His doubts still plagued his mind, yet his body was more than willing as it slowly moved on its own and crawled onto his bed.

"T-This will be a secret just between us ok?" He tried to convince himself.

"Us and only us. A woman hates sharing a lovely stud like you with anyone else." Stephanie as Steve positioned himself before her.

With one last moment of hesitation, Steve sighs before he slowly decides to put his member inside that pinkish wet pussy whose surface was void of body hair and it smelled like female body spray for some reason.

'Ooooh! Thoughts for another time! Just enjoy it!' Steve thought as Stephanie bit her lip with a moan as she wrapped her legs around Steve.

Meanwhile with the others who are enjoying their time at the Spa and everything it had to offer.

''Today was so relaxing" Francine said, getting out of the bathroom with a towel around her head and body.

"You said it, Franny" Roger said as he was her roommate in the hotel room.

"Do you think the others have managed a way to have fun while we are here? I kind of feel bad for them" Hayley said while eating shrimp.

"I'm sure Steve is dealing well with Stan, even though they're mostly being distant." Francine theorized.

"Come on, guys, Stan and Steve may not get along all the time but they do get along sometimes. Kinda makes me jealous that they have a better relationship than me and my dad." Jeff said as they all wore robes.

"Meh, maybe we are wrong and they are having a blast" Hayley said, not caring.

*Meanwhile back to the smith's house*

"TAKE IT! TAKE IT ALL!"

Steve began to mercilessly pound that pussy with fast thrust movements, each pump smacked against Stephanie's body making her whole body tingle with intense sensations of pleasure.

Staying there in Steves's bed, legs spread and being completely dominated by him. It made squeals of pleasure escape from her mouth each time his Bong slammed against her pussy

"Unnhh! Unnnh!"

Steve was grunting with animalistic passion, losing himself at the moment as he kept talking.

"Your mine now! I'm going to use you, fuck you, oh god yes! You're my little bitch now Stephanie"

Throwing her head back Stephanie felt something coming, her cunt muscles felt like grabbing Steves's cock tighter, wanting that cock to slide mercilessly in and out of hern ew milky folds even more, and then...she had a violent female orgasm.

"OH GOD! YES! YES!" Stephanie screamed to the heavens as she gripped him tightly! "I'M CUMMING! I'M CUMMING LIKE A HOSE!"

"Ahhhhhhh Great Scott! I'm cumming buckets" Steve grunted.

With one final thrust that rocked the bed, Steve Smith howled in pleasure to the ceiling as he blasted Stephanie with everything he had in his balls! Filling her up like a turkey on thanksgiving.

What a twist that night ended up to be. No one would ever believe what just happened and neither would he because technically this night never happened and would have to remain a secret. What of Stan's transformation? Was it permanent? Who knows.
