Go with it a little longer

You: "Uh, okay...yeah. I get that."

Veronica: "Good, I'm glad we're on the same page." She says before kissing you on the lips and going downstairs. "I'm hungry, be right back, baby."

Since mom said it would only be a little while longer, you decide to swallow your pride, and be the good brother your mom wants you to be. Galen just needs Veronica's help a little bit longer, and then things can go back to normal. Yeah.

Unfortunately, now that you've shown that you understand the new arrangement, Veronica has taken your silence as acceptance. At the request of Galen, Veronica is now spending a lot more time in the basement, after school, instead of spending any time with you in your bedroom.

Of course, Galen told you that he just wanted to teach her to play video games, and that she could use his desk to study. But he said you wouldn't be interested, and then keeps the door locked. Of course you know why, but the fat idiot still thinks you have no idea you girlfriend is sucking him off down there.

Veronica assures you that nothing is going on down there, although Galen stays naked all the time, rocking a semi all the time. Eventually, Veronica caved in to Galen's request, and she stripped down too. So now they spend most of their time naked together. According to Veronica, whenever Galen wants, she goes on her knees in front of his disgusting sofa, and sucks him off. Sometimes even while he's playing video games, or just watching porn.

Mom: "Brian! Dinner!" You're snapped away from your thoughts by your mothers screeching.

You come downstairs into the dining room, and your mother is alone at the table.

You: "Where's Veronica and Galen?"

Mom: "Uhm...a little busy right now." Your mother is a little flustered, and red in the cheeks.

You: "I can go get them..."

Mom: "No, that's okay. I just tried, they'll be along..."

Sensing something wrong, you get up and go to the basement door. It's unlocked, and slightly open. Mom must have forgotten to close it. As you get close, you can hear moaning, from both of them.

Before you're able to go inside, your mother is behind you, and grabs your arm.

Mom: "Honey, I don't think you want to go down there. But if you do, just remember that it's really....normal. And being normal is...good for your brother. He's been...special, all his life, and this is...finally...actually normal."

You're pretty sure they're just up to their usual tricks, but your mothers behavior is strange. As you open the door, and descend the stairs, the familiar hot ball of lead in your stomach grows hotter in conjunction with the moaning, and the slight sound of something wet, from the pair of them.

You stay silent, and creep down the stairs. Surprisingly, Galen is not on the sofa, playing a game, and Veronica is not at the desk, studying. Looking further down the dimly lit basement, you look at Galen's bed, and find them. Your heart sinks down to the floor from the sight before you.

Galen is on top of Veronica, her legs spread wide, and his fat cock is buried to the hilt inside of your girlfriends pink, wonderful, shaven, pussy. Your fat, disgusting, pervert brother is having unprotected sex with your gorgeous girlfriend.

Galen's fat, hairy, disgusting ass is rising and falling up and down as he frantically, and awkwardly, thrusts his hips forward and backwards, pushing his monster cock you´ve seen so many times into Veronica's moist love canal. The extremely sexual sight of seeing Veronica´s bare pussy for the first time, is slightly marred by the fat sack of sweaty shit on top of her right now.

He's not very good at this, clearly, he's soaked in sweat, his heavy breathing and grunting almost cover up the wet slapping sounds they´re making with their bodies. His frazzled body hair is clinging disgustingly to his sweaty skin, his stupid ponytail swinging in rhythm to his thrusting.

Most disgustingly, the folds of his fat around his abdomen and ass are flapping up and down, obscenely. What a fat, disgusting sack of shit. He doesn´t deserve sleeping with the beautiful girl under him right now.

This is exactly what you feared would happen, when mom and Veronica floated this plan to improve Galen to you. What began as only jerking off in the shower, has ended up in him fucking your girlfriend bareback in the basement. Worst of all, you did nothing to deserve this, or even stop it.

You freeze on the stairs, your eyes locked in on the monster cock invading your girlfriends pussy. Veronica seems to be enjoying every second of this, as much as Galen. Her legs, also shimmering with sweat, some of it most likely from Galen, are clinging hard to the sides of his torso, squeezing his fat folds together. You can´t really see her, Galen´s fat ass is blocking most of her, but he´s clearly grabbing and squeezing her left breast.

You look back up the stairs, your mother has closed the door behind you, and left the basement again. You instinctively zip down your pants and start jerking off, silently, as to not make your presence known. The only thing more embarrassing than your brother fucking your girlfriend, is you jerking off to it. Better not to be seen, he would never stop making fun of you, and bragging about this.

Veronica´s moans are muffled suddenly. Galen has reached up and stuck his tongue down her throat. They make out for a while, with Veronica meeting his kiss with equal enthusiasm. Galen makes tiny little thrusts while he enjoys her mouth.

When their mouths separate once again, Veronica speaks out.

Veronica: "UUUgghhhhh....yeah...you're doing sooo good, sweetie. Keep going....don´t stop....!"

Galen: "F...fuckin...slut...wanted my cock in your guts...ever since you saw me..first...cause I'm so much bigger than Brian...."

Veronica: "Yeah...he doesn't compare...." Her words sting you, but seem to spur him on, causing him to fuck her faster, working up even more sweat.

Galen: "Ughh...! Get...fucked...fucking cum dumpster whore...!"

Veronica: "Yeah, sweetie...mmm!..cum for me..."

It's honestly amazing, the speed at which Galen can work at when he really wants to. Although, his technique is so sloppy, and he's so sweaty, he can't really get a good grip on the bed, and slides all over, fumbling, trying to fuck Veronica faster.

You sit the on the stairs, your bare ass touching the gross carpet that Galen never cleans, clasping your dick hard, frantically masturbating, watching your brother fuck your girlfriend. A few months ago, you would never have believed that Veronica would even give Galen a hug. Yet here he is, his eight inch cock balls deep in her unprotected pussy, fucking like a madman.

Veronica is howling at this point, gasping for air. Her pussy seems to accommodate Galen's cock perfectly, stretching her to the max. Her hands clasp around the back of his neck, around his sweaty ponytail. It's a strange sight, seeing such a disgusting, fat, hairy man fucking an unquestionable goddess of beauty and sex appeal. The contrast between them is staggering, to say the least.

These thoughts, embarrassing as they are, send you over the edge. You ejaculate with more **** than usual, hitting you in the chin as you sit there on the stairs, slumped, watching your girlfriend get penetrated over and over by your brother's cock. Galen seems to be getting close as well, his grunting is getting deeper, and faster.

Galen: "Gonna cum so...fuck...ing hard...."

Veronica: "Me..too...don't stop...don't stop, sweetie!" Your girlfriends squeaking has reached a higher pitch than ever, and her breaths are deeper, more frantic, gasping for air.

Galen: "mrrrhh...gonna cum...inside you..."

Veronica: "No...sweetie.... you promised to cum outside...you promised..."

Galen doesn't answer, and just keeps thrusting, rhythmically. The bed is shaking wildly on account of his weight moving so much, creaking left and right, just like in the movies.

Veronica: "Cum...outside..uhghhnnnnn..sweetie....!"

Galen: "...uughhh...shut the fuck up....cum slut bitch...."

Suddenly, Galen screams a deep, muffled grunt as he buries his cock in Veronica's pussy. He brings his hands around her back in a swift motion, and lifts her slightly up as she squeezes her hard up against his chest, and muffles his screams by putting her right shoulder in his mouth.

As Veronicas head reaches above Galen's right shoulder, she spots you on the stairs, dick in hand, covered in your own cum, as Galen's balls tighten up towards his torso. He's grunting and breathing hard as he creampies your girlfriends unprotected pussy.

Veronica: "Ohhhmmmfffff.....oh...honey...." She says as her toes curl, not sure if she's talking to you or Galen, her legs spasm, and she bites her lower lip in a quivering orgasm, all while her eyes are locked with yours.

Galen: "UUUGGHHMMMFFFFfuuuuuuhh.....I'm cumming! I'm cumming inside you...fucking dumb ass slut...fuck...you...!"

Veronica says nothing, and Galen keeps this position while he finishes ejaculating rope after rope into your girlfriends pussy. Veronica has a slight smile on her face, her eyes are completely relaxed, biting her lower lip while Galen is filling her pussy up with his cum.

Veronica: "Oh...my god...hah....hah...." her eyes are glassed over, enjoying every spurt of your brother's disgusting cum shooting up into her womb.

Veronica and Galen's breaths are calming down now, slowing down with the incredible high of their mutual orgasm. Their sweaty bodies combined into one on Galen's disgusting old bed. Veronica breaks eye contact with you to kiss Galen again. Knowing how much his breath stinks, and how yellow his teeth are, you're surprised she's initiating kisses with him. You look down at their conjoined genitals. Galen's cum has flown back out of Veronica's pussy, squeezing it's way past his cock, pooling beneath them in a puddle of their combined juices.

Veronica: "Hahhh....you naughty boy....you promised to cum outside...that was the only condition..."

Galen: "Nah...cumming inside is better..."

Veronica: "Okay...well, try to wear a condom next time, hmm?"

Galen doesn't answer. You can't believe that they're already planning to do it again....what the fuck.

Feeling now is the right time to leave, you stand up just as Galen starts to pull out of Veronica's pussy. You sneak one last look before Galen sees you. Your girlfriends pussy is red from the cock **** she just took, except for the river of white, sticky, cum leaking down on the bed sheets.

Having seen enough, or perhaps too much, you leave feeling sick to your stomach. Sneakily opening and closing the basement door, you try and clean up in the bathroom, and rejoin your mother at the dining room table. You sit down and share an awkward silence.

You mother finally breaks the silence: "Look, I didn't intend on this to happen, Brian. This is just...nature, taking place. And it's good for your brother, he needs to practice before he's ready for his own girlfriend."

You: "And he needs to practice on my girlfriend, is that it?"

Mom: "I...don't like it anymore than you. But there is no other girl around, is there?"

Hearing the basement door open, your both quiet down. In comes Galen, with a sheen of sweat on his fat fucking body. He's only wearing shorts, and his cock, still wet with a combination of cum and pussy juice, is pressed up against the front, showing the perfect outline of his large, semi-erect cock. He walks up, smiling ear to ear, to the dining table and pours himself a glass of soda, thirsty from the sex. He drinks the entire glass, burps loudly, and pours another.

Galen: "Hey bro. Hey mom."

Wanting Galen to admit what he'd done, you ask: "Why are you so sweaty, huh? What were you and Veronica doing down there? huh?"

Galen: "uh...cause...I was, we were just..." You caught him, the fat idiot can't think of an excuse.

Mom: "Oh my god, sweetie, were you exercising, like I asked?" Galen's eyes go wide, mom just saved him.

Galen: "Yeah! I was...Veronica was showing me how...yeah, your girlfriends really cool, bro..."

You: "Great, thanks..."

Galen: "Mom, bring my dinner downstairs, I need to game with the boys tonight."

Mom: "Okay, sweetie, have fun."

As Galen leaves again, your mother prepares his plate.

Mom: "You have to be understanding for Galen, Brian, sweetie."

You: "I don't know how much more understanding I can be, mom."

Mom: "Galen needs this, I need this! I'm sure that if this continues, he'll move out someday...finally..."

Without allowing you to retort, she goes downstairs with Galen's dinner. After a couple minutes, she returns, and explains that Veronica is embarrassed, and wants to stay down there for tonight. Your mother makes you promise not to be mad, and that you will talk tomorrow.

The next day, you wake up alone in your bed, painfully reminded where your girlfriend is right now.
