Starting with little sister

You walk the girls home just as it's getting dark. You're a little worried about the idiots on mopeds but thankfully you can hear their pathetic rides a block away and steer your convoy of attractive ladies down another street. Back home your sisters would have called you a wimp, even though the toughest dude can't realistically take on a gang of dudes even if they do ride around in 10 horsepower mopeds, but here since they actually feel in danger, they're glad you picked out the sound of the tiny engines and knew what it meant.

You watch TV with your family and Heather, fondling her a bit until your mom yells at you. Mom sure doesn't seem to have given up an ounce of her bitchiness here. You have sex with Heather again that night in bed, because why not? She lets you cum in her pussy but she's on birth control so it's kind of like scoring a touchdown in flag football at the park with your buddies. Not quite the real thing. But still very good.

The next day you sleep in and wake up to find the bed empty in late morning. You're a bit worried as you walk naked to the kitchen. You think about making breakfast but then you remember you don't know how to cook. Your family's pretty traditional, Mom or Ellen always did the cooking. But where's Heather? Where's your family? Did the moped gang abduct them?

Before you can get too freaked out, the door opens and Heather comes in carrying many bags of groceries, more than you'd have thought possible for a woman, and your mom and sisters tell her to put them on the counter, where your sexy naked girlfriend drops them with a thud.

"Why were you grocery shopping?" you ask in a sleepy, hoarse voice, meaning it for Heather, since it seems curious that she's suddenly helping your mom and sisters like this.

"We need groceries so we can cook you food, genius!" your little sister says obnoxiously.

"I was just showing 'em where the market is," Heather says as your big sister starts ordering her to put the groceries away and your girlfriend obeys her. You think about intervening but Heather is living here as a guest, some level of chores are reasonable. You invite her to sit with you so at least they don't make her cook like Cinderella. Ellen makes you breakfast while you look at her ass, and even some hints of her newly shaved cunt lips from behind. Heather catches you looking and you start to feel like a pervert, but she whispers, "Don't feel guilty, you're the man!"

After a late breakfast you have to go to work at the restaurant with Heather for the afternoon shift. Since you're new and she gets treated like crap there, you both get the less desirable shifts for now. You tell the owner Ruth to give Heather a normal slate of tables and the guys look at you in annoyance, since usually Heather had been spending her shift getting railed in the kitchen, and you can't have your girlfriend doing that now. You thought everyone might just laugh at you but the boss had your back and gave Heather tables. Even if Ruth just did because she likes having sex with you (she kept looking at your cock) you gladly took it.

You work a shift as a naked waiter. It sure is weird having your junk out as you try to wait tables, but everybody's naked so that makes it somewhat easier. You feel like a piece of meat with how some of the women customers look at you. You don't really mind, even if they are middle-aged mostly, it's nice to have ladies licking their lips when they see your cock, which is about five inches soft. You're intrigued by the possibilities of all those glances, but you know jack shit about being a waiter and it's a very demanding job as it turns out. You've got your hands completely full (literally) just trying to make it through your shift. After six hours, your feet feel like they're shooting out flames and your brain feels like warm pudding left out too long from trying to keep all those orders straight, keep an eye on Heather to make sure nobody molests her, and smile and laugh at your patrons' dumb jokes. You don't even have the energy to bang Ruth... and she looks disappointed as you clock out and explain you're beat and have to head home. But she says it's your first day and it will get easier.

Finally home, you just want to fuck Heather and watch television. But no sooner do you walk into your apartment than your little sister Katy runs out to greet you.

"You have to help me," she demands. You sigh.

"Mom says I have to get a job!" Katy whines, "Isn't that unfair?"

You blink. "She already made me get a job," you say flatly.

"But you're a boy!" Katy says, "And I'm the youngest. And prettiest."

Heather cackles at your little sister's entitlement.

"Ugh, look," she says, "If I get a job at some popsickle stand working naked I'll totally get ****! I bet the owner will make me suck his dick just to get the job. You have to get on where you work, and protect me!"

"Where's Mom and Ellen?" you ask.

"The beach," Katy says, "Will you help me? She says she's not going to let me use the credit card until I get a job!"

Katy says this like as gravely as if she's informing you she's been sentenced to ****. Heck, it probably does feel like that to her.

"I'm beat," you say, "I just worked my first shift myself. I'll think about it tomorrow."

"Restaurant's closed tomorrow," Heather says, "And Ruth usually only hires on Thursdays. You had lucky timing."

"We have to go tonight! I can't wait a week," Katy says desperately, "I'll do anything."

Your ears perk up. But you can't really make her do what you want to make her do, right? Then again, Heather has been encouraging you to get your sisters to show you some respect. You look to her wordlessly, and she nods.

"Well," Heather says, stepping in to help you out, "Okay then. You have to suck his dick."

Katy looks daggers at your girlfriend, then to you. She seems shocked by it, but isn't screaming like you thought she would. It's more like she's trying to see if you're serious.

"Well yeah," you say, trying to sound confident, "I am totally beat. If I'm going to do this you have to treat me with some respect for a once, Katy."

You think she'll scream **** and tell Mom. She certainly loved to get you in trouble for the previous 18 years of her life when you were pushover. Something about actually acting confident produces a different reaction in her, plus you're remembering how she looked at your dick the night before like she was in awe of its size, rather than disgusted.

"I don't know how," she says softly, "I'm a virgin."

"It's okay," you say, suddenly having a very perverted idea, "But is it really true? You were a very popular cheerleader."

"Yeah, prove you're a virgin!" Heather says eagerly.

Surely this is too much, Katy used to get furious when you even vaguely mentioned her sex life back home. But now that you're humiliating her over it, she's oddly compliant. "O-okay," she says, blushing badly, "C-Can we go to your room though?"

"Sure," you say. Why be an asshole about it? Plus if Mom and Ellen walked in, you're sure they'd ruin this promising turn of events.

You go to your room and Heather closes the door.

"Spread your legs," you say excitedly to your once-bratty little sister, "Show me your hymen, Katy."

Your little sister, with her toned body and innocent face, and those small but firm tits, sits down on your bed, which Heather made for you that morning. Katy spreads her legs, her face beet red already in embarrassment, and shows you her bald pussy. You know she's your sister but you just can't bring yourself to not be turned on by her perfect cunt. She's sexy as hell and obviously into this. You can hear her breathing with excitement despite her blushing.

Your sister spreads her hairless pussy with its tight, coinslot labia lips. You've always liked seeing a woman's most private place, okay so that was just in porn prior to now, but the real thing is giving you a massive boner like you knew it would. Your sister delicately uses her fingers to spread her pussy further so you can see her pink inner folds. Her fit thighs point the way to her cunt, all spread open obscenely. You're looking inside the pink depths of this girl who tormented you for so many years.

At this point, embarrassingly, you can't precisely tell what you're looking at. Jerking off to porn has shockingly failed to make you an expert in female anatomy, despite how much effort you put into it. You see something that could be her hymen, but there's all kinds of pink stuff in there.

"Um, is that her hymen?" you ask Heather, trying to sound confident, like you're just asking for a second opinion.

Your sister suddenly looks so shy and ****, exposed like that with you and your girlfriend staring into her previously unseen vagina. You like this though, since she's giving you this power over her willingly. You and your girlfriend are expecting her cunt, looking at her private inner folds, she's showing you everything she has hidden for her whole life until now.

"Houston we have a hymen!" Heather says teasingly, leaning over and looking up your sister's cunt. "But unlike her big sister she's not a frigid virgin. She's as soaked as a leaky double-wide trailer in a Florida hurricane."

You laugh at your girlfriend's ridiculous analogy. This woman is such a spaz but you enjoy her sincerity so much.

From looking up your sister's cunt, which you can at least confirm is quite wet, despite what you're doing to her. Or rather, because of it. It turns out the sassy brat secretly likes to be humiliated. She likes having to show her pink cunt to her brother and his slutty girlfriend. You grin and your confidence only builds alongside the size of your penis.

"Now you have to pleasure me, Katy," you say, "But don't worry. If you show me the respect I deserve, I'll defend you all summer. No other man will touch you."

She smiles softly, closing her legs then dropping to her knees on your bedroom rug. "T-thank you," she said, "I believe you. That's the only reason I'm doing this..."

You step forward, your ten-inch boner pointing at your little sister's sweet lips. "Help her," you command your girlfriend.

Heather nods and kneels next to Katy. Now you have your sporty sister and your big titted girlfriend naked before you. It's going to be tough to not cum in 30 seconds even from a newbie's blowjob. Those are your sister's lips after all. This is so wrong... but that makes it all the hotter.

"Okay he's not going to ram it down your throat," Heather says, and you detect some pride in her voice, because Heather certainly let you ram it down her throat. "He'll just stand still. Play with it. You're curious about cocks right? You're not a lesbo?"

"No way!" your sister says defensively, "I've never seen one in real life, except some creep who whipped it out in the car once. But this I actually like. If he doesn't **** me."

"Calm down, nobody's **** you," Heather says. "That sucks about the creep though. But now's your chance if you're curious about dick... just touch it."

Your sister nods and reaches her little hands up, holding your dick like some foreign object shes examining. But it feels exciting, she really is curious about touching a penis. You're happy to be used as a research tool.

Katy fingers your cock, holding it up and letting it drop, getting a feel for what a dick is like. She touches your balls, holding them curiously. "Did you like sucking on them yesterday?" she asks your girlfriend.

"Oh yeah," Heather says honestly, "He has big balls, they felt good in my mouth. I liked how he was horny and ordered me to suck them."

Katy blushes and actually whimpers in embarrassed excitement. You love them bonding over how they like your dick and balls. Now Katy is treating your girlfriend like a skilled teacher, not a disgraceful slut. You like that too.

Your sister puts her hand around your cock. "It barely fits!" she said, "He's way bigger than usual right?"

"Yeah," Heather says, "Lucky us. Seriously. Bigger is better."

They both giggle and their tits jiggle, Heather's much more than your slim sister's. But both women have lovely bodies.

"Mom would disown me," Katy says, "Fuck her though. I like this." She leans in to kiss your cockhead. Your sister is putting her mouth on your penis.

"Fucking sexy," Heather says, verbalizing your thoughts, "Brother and sister. Suck your brother's cock, Katy. You know you want to."

Katy looks down in embarrassment, but then kisses the tip of your penis again, right at your pisshole. You shiver in pleasure. Her lips are kissing your dick. You want to shove your cock in her mouth, but control yourself. She's going to give you a very willing blowjob.

Your 18-year-old virginal sister opens her mouth and takes your cock in slowly. You feel the warmth of your sister's breath on your penis.

"Careful not to use your teeth, open wide," Heather says. Her perverted tutorial turns you on even more. Katy obeys and takes the first few inches of your dick into her wet mouth. You press your dick down on Katy's tongue. She very much feels like your sister in this moment, this girl you've known all your life, but that's okay. You clearly aren't opposed to ****, okay you're a horny bastard, but she didn't even resist giving you a blowjob. Your bratty sister is an incestuous pervert.

You grin and press your cock forward just a little bit. You mustn't be rough with the inexperienced cocksucker. "Mmmm Katy your mouth feels good," you groan, "Suck my cock, sister."

She tightens her lips around your shaft, clearly liking the dirty talk. She takes almost half your ten inches then starts to gag and pulls back. You miss Heather's experienced throat, but the fact that this your little sister sucking you off enthusiastically makes up for the lack of expertise. Katy moves her head back and forth, rubbing her lips along your dick.

"Use your tongue," you command. "Lick my dick."

Despite being so degrading, she instantly responds by pressing her hot tongue against your cock. Heather, always the pervert, is masturbating shamelessly. "Yeah! Suck your brother's dick! This is hot as fuck!"

You press your cock against your sister's throat, making her gag just a little. She's clearly not ready for the rough stuff so you stand still, letting her eagerly suck you off. You're turning your sister into your whore, everyone here knows it. This is hot as fuck, like Heather says.

"Suck it, sister," you say, "Let me cum in your mouth."

"Don't down her," Heather says with a grin, "I never had a guy cum so much. But it was incredible."

Despite the memory of how much cum you make, Katy sucks even harder. Her lips are tight on your shaft. She takes slightly more than half of your length, making herself gag softly now. You look at her coin slot cunt and she's rubbing her clit, masturbating to her own incestuous blowjob. You can't hold back and groan loudly as cum surges through you, ropes of it shooting into your sister's mouth uncontrollably.

Katy holds her mouth open. With your sister not understanding that she's left you hanging, Heather grabs your dick and starts milking your sperm out, to your relief. You feel your sisters mouth with jizz, the white stuff is literally filling her open oral cavity, almost spilling. She keeps her jaw stretched as wide as it goes, letting you use her as a sperm receptacle.

Your sister's mouth full to capacity, Heather points your dick at Katy's tits and paints them with jizz. Then she milks out the last of your cum onto her own big tits.

Katy swallows somehow, her eyes going wide at fully tasting your sperm, but she doesn't seem offended. It's clearly too much for her though. Heather leans in and slurps some of your cum out of your sister's open mouth.

"Fuck, eat my cum, both of you," you command in delight. You've never seen this particular perverted act even in porn.

Katy swallows again, looking at you submissively, then opens her mouth again, offering up some more of her brother's cum to Heather. Your girlfriend has to poke her tongue into the cheerleader's mouth this time but scoops out your jizz and swallows. Katy swallows again. Damn, was that four mouthfuls? It's like you're making a pint of sperm, maybe it's how you're walking around horny all day with the nudity.

There's still cum on their tits. Katy gasps as Heather licks her tits clean. Undaunted, your sister licks your girlfriend's big tits like your cum is icing on a cake. You never thought about them being bi. You are getting horny enough for more sex, especially with the possibility of exploring these latent bisexual tendencies... but no, you are a man of your word.

"Okay Katy," you say, "Let's go get you a job."

Glad I can write again. Are the chapters too long? The scroll bar at the side gets so small, but I like describing what's going on in detail. And any thoughts on what next? I have plenty but I want to be responsive. Thanks for the comments and likes!
