One day Steve had the WORST case of blue balls where he was unable to cum through normal means, but after his beautiful hippie sister helped him out with his pent up balls. The geek finally had the orgasm of a lifetime and was relieved from the pain...however! It was discovered that for whatever reason Steve was no longer going able to cum from only masturbation or sex toys.

So now Hayley has to constantly help Steve whenever he gets horny (which is all the time) having his huge blasts of cum and sexual energy as her reward, it was now her new drug. Her little brother fucked her so good that Hayley couldn't have any other man but him, for every fuck session he improved thanks to her tips in pleasuring a woman.

Unfortunately one day the family decided to go eat in a new restaurant that had opened stopping their diary fuck session in his room that took a long while to be done. It was annoying but something that had to deal with, maybe waiting for it will only make it better later.

"It's nice to get out of the house sometime like this right Stan?" Francine said, enjoying her meal.

"Uh...Yeah, I guess" Stan was typing on his phone.

"Stan! Stop messing with your work for once and try to socialize with your family," She said, annoyed.

"Ugh! Fine, so how was school or whatever?" He asked, not interested for real.

Hayley and Steve looked at each other and gave a nice and warm smile.

"It was ok" They both said in unison.

"Alright…?" Francine said a bit weirded out.

What Stan and Francine didn't know at the time was that while at the table the siblings were secretly feeling each other up. Hayley was grabbing and rubbing her little brother's huge cock and balls under his pants, feeling how warm and twitchy it was. While the geek enjoyed groping her butt, feeling what type of panties she was using today, ready to fuck at any second.

'Fuck I can't wait to have that up to my holes' Hayley thought kinkly.

'This bitch of a sister sure is getting some more meat there hehe' Steve thought pervertedly.

The mother of the two finds it weird how the two of them seemed to be closer now than before, but maybe that was a good thing? That's how siblings should act instead of fighting all the time, finally getting along would be just perfect.

Later that night after coming back from the restaurant everyone was asleep...except Francine who decided to get up and grab a cup of water only to conveniently hear some noises coming from Hayley's room when going.

"Hmmm~''

'What was that sound?'

Feeling curious, the housewife milf decides to investigate, slowly peeking inside her daughter's room like a spy and see what she was doing. What Francine saw there was so shocking that she surprised even herself for not screaming right off the bad.

'Oh. Mighty. Fuck.'

Her daughter, Hayley smith was completely naked and on four in her bed. She had something in her mouth which was a gag ball from one of those BDSM items you see on porn movies, at first she thought the hippie girl was just having fun by herself and exploring new things but that was wrong.

Someone was fucking her from behind, so much so that her eyes were rolling in her head, which made the gag ball make more sense. Now, who was fucking her you say? No one more but STEVE SMITH!

But that wasn't possible, right? They are siblings, that was incest, and...was her little guy really that well endowed? She could see the size of his cock and balls, they had grown to a size she thought only a few chosen ones had and that's why they worked on adult entertainment.

"Ahhhh-Hayley, it's coming" He moaned.

"Hmmmm~" Hayley moaned what could be a yes.

The big dicked geek removes his member from his sister's hole and then starts rubbing it frenetically before he unleashes a monster load of cum all over the gagged hippie girls back, it was like a whole bottle of whipped cream suddenly burst all at once on the cake.

*SPLURT!* *SPLAT*

"Ahhhhh! Fuck yeah~This always feels so damn good" Steve said, with a smile enjoying the sensation of bursting huge loads.

Seeing that unfold right before her eyes Francine is awestruck by that. Steve has a huge cock and balls the size of oranges, Hayley was gagged and just recently fucked by said log and then the sperm that came like a wave hit her back in such a slutty way.

"BUSTED!"

She just went in and said that what they were doing was just something that was forbidden such as watching an adult movie at night while still being too young for it, but in this case, she just didn't have any better words to speak and went with it like auto-mode.

The two of them look back in shock seeing their mother just caught them in the act. Steve let go of his sis arms and Hayley rashly started to take the gag ball off.

"Mom? What the...were are you spying on us?" Hayley asked.

"Oh crap!" Steve said sweating buckets.

"What do you think the two of you are doing?" She knew the answer but still felt compelled to ask.

"Well looks like we got busted Steve, and even after all those weeks"

"W-Weeks?" Francine thought, surprised that they were going at it for weeks and not just today.

"Calm down mom W-We can explain" Steve began.

"For some reason, Steve dick has become unable to cum without the help of a female touch, so I have been helping him all this time, however, his dick is getting harder to go down and his balls have such thick sperm is like cake icing" Hayley said bluntly.

"H-Hayley! When you say it like that" Steve felt embarrassed.

"Cmon Steve I'm only saying the truth, look how hard your cock is even after that blast, you drenched my back like a shooting target" Hayley said with a wink.

"Steve...Hayley...What you two were doing is wrong, not only you didn't bring him to a hospital to get that check out you have been lying to me all this time" Francine said oddly serious.

"Well it wasn't exactly something we could just say over a cup of coffee" Hayley said in a sarcastic tone.

"Please" Francine kindly closes the door "You can't handle that all by yourself all the time, allow me to assist you"

When Hayley and Steve heard that they thought something was wrong with their ears.

"...What?" Steve asked in a dump truck fashion.

"Who would know my special little guy was more hung than his father? You got quite the bank account there Steve. Would you mind sharing it with mommy?"

Francine asked in a seductive voice while showing her cleavage, Steve's cock twitching in response.

"Are you freaking serious?" Hayley was naked and still surprised.

"Oh pipe down Hayley, I don't have time to act like I don't want this for the sake of normalcy and pride. Do you have any idea how hard it is for me to have an actual good amount of satisfactory sex?" Francine gave her the stink eye,

"Well you did have that one poltergeist made from your sexual frustration but…"

"Shhh! Hayley please, mom is in uh...need of help maybe we should listen" Steve said eagerly about it.

"Oh! So now I'm not enough for you?" Hayley glared at him.

"Sit back and let me show you how it's done, Hayley. Big boys like that need a little change in their diety from time to time"

Pushing Hayley to the side, for now, the blonde-haired milf gets near the edge of Steve's bed and takes a quick glance at his meat. It was so big, rugged, throbbing, and long, just the way it should be.

'Marvelous'

Francine then started by slowly wrapping her fingers around his member just to feel it first. Steve moans lightly at that and she began rubbing him off with one hand while the other decided to squeeze a little out of those pent up balls, she could swear they were talking to her to get out.

"So manly. You're growing up too fast honey"

"Ahn! M-Mom!" Steve loved how his mom touched him.

"You love mommy stroking your big dick and fat balls" Francine said to his ear.

"Oooh! God yea" Steve bit his lower lip.

"Then let's keep going"

Starting to get horny Francine shoves Steve's face on her bouncy chest where his voice was muffled by the softness. Then her hand motion increased in speed, rubbing his meat faster and harder, while the geek moaned louder.

"Can't have you moaning too loud Steve. Your father is sleeping"

Francine would do intervals between going slow and fast so the boy would cum too fast. When she felt he was close to it she would instead stop and just shake her boobs on the guy's face while the pepperoni log twitched.

Steve was enjoying himself, rubbing his face left and right on his mother's bosom while she caressed his dick like that, it was like one of his wet dreams but now being made real.

'Ohhh yeah! OHH FUCK! God I'm so lucky now please don't let this be a dream"

"Don't you think that's enough?" Hayley asked, feeling annoyed.

"Yeah your right, he needs to breathe eventually"

Doing so and stopping the breast attack, Francine lets Steve breath….for approximately five seconds before going for a kiss.

"Oh c'mon!"

But Francine didn't just kiss him, she french-tongue kissed him with such force it was like her mouth was asserting dominance over Steves's tongue on a wrestling match, the geek felt like his mom was trying to drown him on her kisses, all the while not stopping with her rubbing session on his dick.

Steve's eyes were starting to roll at the back of his skull at his mom's hot assault.

"Hmm~ Yeah this is good enough" She finished the kissing.

"Uhhh~" Steve's brain melted.

"Your cock is huge and ready for the next step" Francine gets off the bed.

"Next step? And what is the-WHOA!"

Steve was surprised at how his mother seemingly decided to just go for it and put his dick in her mouth. Proceeding to suck his cock head while holding onto his thighs and inserting more doing a deep blowjob, sucking in and out with sloppy sounds.

"OHHH! M-MO-

Steve was silenced by Hayley who put her hand on his mouth to prevent him from moaning too loud.

"Be quiet or I will be the one putting that gag on you little bro"

Hayley watches how her mother went downtown on the cock that was just recently having its way with her. Big cock being sucked, balls being groped, and all the jazz.

"You must be liking this huh?" She goes to his ear "Having your mom suck the cock that was just a few seconds inside your sis pussy hmmm?~ I bet you just want to cum and make her swallow your thick smelly cum" Hayley said licking his cheek "You little motherfucker perv"

'OH GOD!'

The amount of pleasure was astronomical for Steve. His mom sucking his cock and playing around with his balls and Hayley talking dirty on his ear, truly an orgasmic moment.

Like some cliche LIMIT BREAK, it just burst forth and Francine could feel how it gushed out with such force her cheeks were quickly filled to the brim with cum. Taking by surprise just how much he really let it out Hayley laughed how Francine tried to get it all but some ended falling to the floor anyway.

"Looks like you got more than you asked for. Maybe you're just rusty, then again who can drink this cum machine right here?" Hayley looked at Steve.

Francine got up and swallowed out the rest of cum she managed to salvage before it was now in her stomach.

"Oh. My. God…..Steve that was pretty damn impressive" Francine said with a serious tone of voice "You are really making me soaking wet here, I can't wait anymore. I need you to fuck me like...right now"

"W-What? But mom.."

She then rips off her pajamas like they were just glued to her body and were easily removable. Steve stared at her naked body in awe and still hard even after two blows.

"You're just what I need Steve. A big cock that doesn't easily get tired, you may cum a little too fast but that's because I'm better than Hayley"

"HEY!"

"Sorry Hayley, but mom just got my full attention"

"Fine! But I want one thing before she starts" Hayley said.

"And that is?" Francine pondered.

*A few minutes later*

"Yep, this is quite interesting"

Hayley was currently recording in her phone the scene where Steve was fucking his mom Francine in the missionary position. Both of them were using gag balls around their mouths so the sound of their moans can't be heard, but by looking at Francine's face and her eyes plus saliva, I think Steve gave exactly what she wanted.

Steve humped her like a freaking animal, the bed shook so much it's like it would break. He too had an indescribable face when fucking his mom like punching her womb the way his huge log went in and out of it was amazing, after that there was no way her pussy would be tight.

"HMMMMPP~" 'OHHHH YEAH! OHHH FUCK! MOM! I LOVE YOU SO MUCH!'

'AHHHHH SHIT! FUCK! FUCK! FUCK! SO BIG! ALL MY LIFE WITH STAN WAS A LIE OOHHNNN~"

That night didn't end with just one creampie...in fact, it ended in multiple ones such as mating press and Doggystyle. Francine looked like she gained a few pounds on her belly after Steve was done pumping her up, a new member to ease Steve's burden of constant hornyness a bit more.

'YEAHHHHHHHH!' Steve mentaly screamed after filling his mom to the brim.
