A\N: Shout out for the Guest guy who asked for female Stan, No dude your not the only one who thinks that form of him was sexy, it could be even better if the voice changed too. I was doing that chapter with energy but I accidentally erased most of it when using Grammarly which made me sad -_- all that work went just like that, I don't have the energy or determination to try again so I'm just going to move on to the next idea. Sorry for being such a dunce sometimes.

-PENT UP-

Co-written by Jss2141

In the city of Langley Falls there was the Smiths residence, and right now Steve smith the unpopular geek was going through some really difficult moments of his life.

For some unknown reason, he was unable to do one thing...no matter what he did or used, the guy was unable to bust a nut. It was living hell, for a young boy full of hormones being unable to cum for one whole week even though he really wanted? Hand, fleshlight, humping his pillow like a dog in the heat...NOTHING!? Poor guy felt like a lock had been put in his sack.

To make matters worse his genitalia was left incredibly sensitive like he's on the edge of cumming all the time, but it just won't go all the way. His was so pent up due to this anomaly his balls ended swelling up with cum growing to the size of softballs.

"Ugghhh! Cmon! Cmon! CMON!"

Every freaking minute of free time was used in him trying to bust a fat load, beating his meat so furiously that the friction let it pulsing red.

"Why is this happening?!" Steve asked in a frustrated panic as he kept jacking and jacking but got no release.

Everything had been perfect for it too. His father was on a mission, his mother was out shopping, his sister was at work, and Roger was off doing who knows what with Klaus tagging along. He thought a moment like this was what he needed to finally cum but he was still denied.

However, luck was not on his side, because something happened at his sister's workplace and she had to come home earlier from Sub Hub.

''God I hate that place sometimes, why do they have to act so sensitive because of one slip up?"

The black-haired sexy women wanted to take a shower and maybe smoke some weed to relax later in her room...but she ends up hearing something

*THUMP*

"What the!"

At first, Hayley thought she was alone, but now? Curiosity gets the best of her and she decides to go investigate. Once upstairs she hears the sound of muffled moans coming from her brother's room and also swears.

"God damn it! Come on, fuck!" She heard him swear as she grew curious about what he was doing.

"What the hell is Steve doing in there? It sounds like he's trying to win a video game." Hayley mumbled to herself as she put her hand on the doorknob.

What she couldn't predict was that the moment Hayley opened the door to check out on him, the hippie girl ends up seeing her nerd brother...naked and furiously jerking off what seemed to be an eight inches big cock, while humping a fleshlight trying to achieve the sweet release of an orgasm.

She Gasps "OH MY GOD!"

Steve hears the sound of her voice and turns around in fright of who found him

"What the! Hayley? The heck you doing in my room? Oh geez, no one knows how to knock anymore?" He said not even stopping his activity.

Hayley didn't reply to his complaining, she couldn't, as she hadn't taken her eyes off her brother's raging erection and large blue balls! She had never seen anything like it and was unable to look away as she was making a mental comparison to Jeff and his tool.

'Holy shi...Steve is hung?' "G-Good grief Steve, I know you were a perv but what are you even doing? Your dick looks like its gonna blow up any moment now"

"That's because I am UNABLE TO CUM! It's like someone cursed me, I try and try again but NOTHING" Steve said really frustrated.

"Oh...Have you thought about seeing a doctor?" She offered.

"Do you think that my social life is so low that I can just go out in public like this and tell them my embarrassing condition?"

"Well..." Hayley said as she kept staring at his erection and thinking she was hallucinating cuz she saw steam coming off it. "Have you tried..."

"I'VE TRIED EVERYTHING! NOTHING WORKS!" Steve shouted as he shut his eyes and kept humping the fleshlight, not seeing it begin to crack. "PICTURES, VIDEOS, LUBE, NOTHING I THINK OF WORKS AND IT HURTS! SO! MUCH!"

"Oh...I'm sorry to hear that? Maybe what you need is something more real"

What Hayley said suddenly made Steve mind click with an idea, stopping the humping he then looked back at his sister and back to his member. Gulping down nervously the geek then decides for a leap of faith.

"You know Hayley...Maybe you can help me out with this if you know what I mean?" Steve grins.

"Help how? Wait...your not asking fo-"

"Yes, Hayley I need a helping hand, that type of helping hand. I have no patience to beat around the bush, please help me get released, I promise I do anything you ask of me later" Steve begs for it.

"Any...thing?" Hayley asked as she still eyed his dick, feeling both disgusted and intrigued for some reason.

"Yes, anything! Any favor, chore, or problem! Just please help me!" Steve begged, even more, gritting his teeth as he erection flinched with each heartbeat!

Seeing how desperate Steve is Hayley gives in and decides to help him starting by giving him a handjob that leads to surprising facial but even after cumming buckets from her handjob Steve is still hard and Hayley give him a blowjob and lets him fuck her each time steve cums gallons of pent up sperm.

Hayley can see how desperate her brother is, and having him in the palm of her hand could be useful in the future...eventually she comes to terms and decides to help him.

"Fine, just sit at the edge of the bed or your chair and I give you a hand"

"YES! T-Thanks"

"Whatever"

Steve got up and quickly sat on the edge of his bed, waiting in eagerness as Hayley stepped into his room and locked the door behind her. She didn't want anyone walking in like she did, for both her and Steve's sake.

"Ok here I go"

She started to slowly wrap her hands around his shaft, which in turn made him moan way louder than what was normal for this basic thing, Hayley proceeded to pump his cock up and down to try and give him pleasure while grunts could be heard from her geeky brother.

"Oohh~Hayley your hands are so soft" Steve smiled like a doofus.

"Yeah, well...I moisturize."

Hayley said as she tried not to stare at his cock or make eye contact, feeling pulse with heat as she kept rubbing it.

'Oh god, why is it so warm?!'

She thought to herself as she took slight glances at his cock before moving her sight down to his big slightly blue ball. '

'And how are his balls so big?!'

"Ahhhnn! H-Hayley I'm feeling something, g-go faster please, and squeeze my balls" Steve drools.

"F-Fine but I'm not doing it because I want to"

Hayley obeys and starts stroking his dick faster than before and then grabbing his balls giving it a good squeeze.

"Oh! ...oH! OH! OH! AH!" Steve moaned.

"Steve?" Hayley asked, worried.

"For some reason, your hands feel way better than anything else sis"

'I'm not going to reply to that. Just finish helping him, leave, and wash my wands.'

Hayley thought as she moved her hand faster and squeezed his balls a bit harder, making Steve moan louder than before!

"OHHHHH...YEAHH!"

Moaning like this was his first orgasm of two lifetimes Steve ended up giving Hayley a big surprise...in the format of buckets worth of cum blasting off right at her face, it was like a grenade had blown up in point-blank range but it was like whipped cream.

Hayley was left stunned as her face and work uniform were covered in Steve's cum, which was literally steaming like a hot meal!

'Oh...GOD!'

That was her only thought as the cum drizzled down her face and some slowly moved into her opened mouth from her upper lip!

"Ahhhn thanks the heavens! I just need a feminine touch and then SPLURT! Hehe, you look so hot when covered in my cum sis" Steve said, boner still hard and everything.

"Oh shit, it's in my mouth" Hayley got up trying her best to get clean.

She could feel it in her mouth...it tasted sweet with a somewhat spicy aftertaste, creamy and thick even at the smallest drops. Hayley had just masturbated her little brother in his room and the latter blasted off a heck of a shot worth in pure protein at her face and with the Sub Hub uniform? She was like a sandwich covered in mayo.

"Ooh god, Hayley! Thank you! You have no idea how good that felt!"

Steve fell back on his bed as he breathed heavily with the goofy smile still on his face. So many attempts to release and now, it has finally come! Or so he thought as he still felt hard and his balls aching.

"You know...Maybe we can keep this going. I mean, does Jeff even have half the meat log I got?" Steve tried to convince Hayley on doing more.

"Uh, maybe."

In her state of shock, Hayley didn't know when but she had grown horny from the taste of Steve's cum and now her body was subconsciously craving

"I...I-I can try out a little more if you're still feeling the pain of course. Can't let the help be unfinished" Hayley said trying to act like she was not getting horny.

Steve smiles at that as he leans back up, nodding at Hayley a bit too fast but she was too dazed to notice.

Gulping down nervously she stares at his member for some time, before slowly opening her mouth and bit by bit wraps goes to sinking her throat on the steam sausage.

"OOH! AH!"

Steve couldn't hold back as he was sensitive after that first wave and still recovering.

'Is he gonna cum again? This soon?!' Hayley thought, dump truck.

"HAYLEY!"

Steve grabbed his sister's head with both hands and shoved her mouth deep into his cock reaching the hilt.

"TAKE MY CUM BIG SIS"

The nerdy boy humped her mouth a little more before he ended up cumming like a geyser once more, filling Hayley with so much sperm her cheeks got poofed, coming even from her nose because the amount was not something she got used to. Steve did however manage to make her swallow a lot and her belly felt like she just drank four milkshakes.

'OH GOD! THERE'S SO MUCH!'

She thought as she felt her stomach fill and her mind become even more dazed.

'And it's sooo...GOOD!'

Once Steve was done with his premature orgasm he realizes what he just did.

"Oh shit! Sorry Hayley, I just got so into it. Are you ok?" He asked worried that his sister drowned on his cum.

"Yeah, I'm fine" Hayley said as she used her Sub Hub apron to wipe off her face, taking small licks of his cum as she smiled under it. "In fact, I feel much better than after I got off my shift."

"Oh...Good to know, maybe I should take a shower"

"Now wait a moment little brother, you can't go now. You're still hard, and now we are gonna need something a bit more special to pump out that last drop" Hayley said now more lustful.

Standing up before Steve, Hayley sent him a lustful gaze as she began to slowly undress from her cum covered work uniform.

"H-Hayley" Steve asked confusedly.

His sexy Sister was getting fully naked in front of him. Showing her beautiful smooth skin and nice curves.

"Now the real fun begins Steve. Hope you are ready"

'I-Is this happening?! She really wants me to fuck her?!'

Steve was so in shock that he couldn't react as Hayley sashayed over to him and gently pushed him on his bed and straddled him, rubbing her pussy against his lap and her ass against his hard again hard-on.

"Oh yeah, your cock is so big Steve. It's really making me go crazy, how about we get rid of that annoying V-card of yours? That way we can both have a good time" Hayley said not taking no for an answer.

"Oh shit! Ahn...y-yeah! Let's do this sis, if you want it for real then I won't complain" Steve said, not finding the moral to say no.

"Good, cause I'm about to rock. Your. World." Hayley said slowly as she looked down at Steve, not breaking eye contact as she grabbed his cock and lifted herself up to align with her pussy.

"Oh...boy here it comes!"

Steve braced himself when his sister was about to put his steamy hot cock inside her pussy.

"Ahhhnn!~Yeah, this feels great" Hayley moaned feeling the tip get inside "Gotta put all of it in"

Hayley continued to go down on his cock as she bit her lip and trembled at the feeling.

The lustful girl continued to go down on the geeks cock as she bit her lower lip and trembled at the exhilarating feeling of getting penetrated by a big cock, a true big phallus.

"Oohhnhnhn fuck, my head is going blank" She said.

A few more seconds and now Hayley had all of Steve's cock inside her as she was face to face with him, looking into Steve's eyes as the lust was overwhelming.

"Huh...huh...Steve, move." She said to him as she didn't break eye contact.

"W-What?" He asked softly as Hayley glared at him a small bit.

"I said MOVE. Start...humping." She ordered him.

"B-But you're the one w-who is on top of ME!?"

Steve then lost his senses feeling how great his first feeling of pussy around his dick was. Using all of his strength he changed positions from a cowgirl position to a missionary position.

"Take my cock, Hayley!"

He shouted at her face before moving his hips in and out of her pussy at a slow pace that was increasing by each second.

"Uh! Uh! Uh, god! Yes! Keep going!" Hayley said with husk as she wrapped her arms around his neck as he kept fucking and getting faster.

"I never dreamed you would be the one Hayley" Steve moved his hips faster hitting her deep "Fuck! Tell me how much you wanted this Hayley, tell me how much of a slut you are"

Steve moaned as his big cock went balls deep in her pussy, in and out making the bed shake with the pace that was now slightly getting out of control.

"I want it bad! I want it real BAD!" Hayley said as he grits her teeth at her brother inside her! "I didn't want to think about it but from the moment I say it, I want it so badly!"

"From now on whenever I feel horny you're gonna satisfy me right Hayley?" Steve smirks dominantly "Because your husband ain't got a lump of meat like this"

"Yes! YES! I promise, Steve!" Hayley said with moans as Steven kept his pace.

"UGH, I LOVE YOU HAYLEY!"

The two of them start making out with each other while Hayley got her pussy hammered by her little brother's huge dick, and Steve enjoying the taste of 'Both' his sister lips giving him love.

It was only a matter of time before the last blow was going to blast off.

"C-Can I cum inside?" Steve asks.

"YES! FILL ME UP LIKE A BALLOON!" Hayley shouted as she pulled Steve into a surprising kiss!

*SNAP*

Then it happened. Steve opened the doors of the den and groaned in pleasure releasing his pumping shotgun shells inside her womb at full speed.

1h ago'OH GOD! YES YES YES! GIVE IT TO ME! GIVE IT TO ME!'

Her thoughts were at an all-time sexual high as she clenched her pussy around his cock as Steve filled her up, distorting her stomach a bit at how much he was pumping in her. The kiss grew rougher as they wrestled with their tongues like a horny French couple!

*A few moments Later*

"Whoa..."

Steve said in awe while he and Hayley were laying in the bed naked after what they had done. His dick now finally going limp and flaccid from all the cumming.

"This was crazy huh?" Steve said.

"You're telling me? My pussy feels sore now and you pumped me like a thanksgiving turkey" Hayley smiled.

Steve chuckled at her comment as he looked at her stomach, seeing that she was as stuffed as a turkey with the "stuffing" overflowing out of her.

'Geez...she's gonna need more than just one pill of the next day from that' Steve thought

'I wonder if I get pregnant with all this' Hayley thought
