The sister's first naked outing

After cleaning up yourself and turning off the water, you tell Heather to dry you off. She's all lovey dovey because you're treating her like your girlfriend. You think probably no guy's ever done that in her whole life, they've just used her for sex. You're aware that most guys would think you're an idiot for treating a slut this way, "why by the cow when you can get the milk for free?" they'd say, but Heather's nice to you and she's fun to be around. You don't really care what other people say.

You show her your dinky room for the summer, with its view of the wall of the building next door.

"Thanks, man. I'm so glad you're letting me stay here," she says, as if still half-expecting you to laugh and kick her butt out the door.

"Yeah sure," you say, "I like you. And your ideas about what I should do with my family."

She grins. "You deserve to be respected at home."

She sees your video game system and wants to play. You like to game and figure this makes her an even better match. She's pretty good at video games but so are you. You always played fighting games with your buddies back home but this is a million times better, you can grope Heather or suck on her nipples in between matches. Sure couldn't do that with your nerdy friends back home.

Eventually it's dinner time and you wander out to the kitchen, where mom has made a chicken stir fry.

"Why is she eating dinner with us?" Ellen asks, looking at Heather.

"Cause she lives here now," you say, "In my room. It's no big deal."

"I can pay rent, and cook," Heather says awkwardly.

"I could do without food cooked my a slut," Ellen says.

"Yeah she'd probably get cum in it," Katy says with a smirk. Mom doesn't put a stop to this, she actually looks at her daughters approvingly. You hold Heather's hand under the table as you eat but you get the impression this is far from the first time she's been insulted cruelly for being a slut.

Dinner tastes good, at least, Mom sure can cook. You stare at Heather's tits but not your mom and sisters - another thing your blond girlfriend is good for, keeping you out of trouble with those bitches.

After dinner Mom says, "You girls haven't left the apartment yet! I want you to go take a walk around the neighborhood at least. Your brother will go with you so you feel safe."

"I'm not sure he'll be much use," Ellen says with some snark.

"Oh well he's better than nothing, and his puppy dog will follow him," Katy says, "If perverts try to **** us we can just offer her up."

You'd bicker with them but that's never accomplished anything at all. In fact, arguing with them instead of taking action to shut them up seems like half of the reason they've walked all over you for so long. You grab your sisters by the wrists. "Come on girls, you heard mom, time for a walk!" you say.

Shocked by your newfound confidence, Katy and Ellen don't resist as you pull them up and lead them to the door. Heather gets behind them, blocking an easy retreat. They might resist anyway but for a once Mom helps you out. "Yes, go with your brother and his girlfriend. Come on now, scram!"

For a once your sisters don't drag their feet and whine, perhaps they're shocked that Mom isn't on their side and you're not being a total pushover, two things which have never happened before. Heather helps you herd your naked sisters down the stairs and out into the front courtyard.

And then your sisters are naked in public for the first time.

At this point you've gotten relatively used to being naked in public. You're worried about getting a boner, which apparently a big faux pas here, but after a day of sex with Heather you think you've got that problem under control. You just won't look at your sister's shaved pussies... not that they should give you a boner, but let's be real.

They are pretty attractive, Katy looks downright innocent even naked (of course you know better). With her more mature body at 23, and especially her freshly shaved twat, Ellen looks like walking sex. You wonder if she's even had sex... but again, not something you should be thinking about. Still you can't help looking at her bare pussy lips, so tight, and the skin is pale. They've probably never seen sunlight, it's not like your sisters sunbathed back home, they said you'd just try to look at them naked if they tried. Well, maybe that was true.

But now you didn't feel bad about it. You lead them to the end of your quiet residential street where nothing much was going on.

"See?" you say, "Being naked in public is no big deal."

Your sisters are blushing badly. You've never seen them like this - embarrassed, naked and looking to you and even Heather for help. You can see every detail of their bodies, even their pussy lips. You know you shouldn't be thinking what you're thinking, but then again, they've always been so mean to you, and you're the only one on the island who'll protect them. Is it really so bad that you look at their bald pussies and nice tits? It's all the reward you'll expect.

"We'd better go back, we'll probably get ****, with our bodies," Katy says as the group walks slowly with no evident destination, but your steps take you closer to the main street.

"They're not that hot," Heather whispers to you as the foursome walks.

"What did she say?" your little sister asks quickly, looking for a fight.

"I won't let you guys get ****," you say, "Calm down. Just enjoy being naked in public. It's not that big of a deal."

They walk with you out onto the main boulevard to the beach. All three women are close to you, Heather because you're the first guy who doesn't treat her like crap. Your sisters because they don't want to get ****. You seriously doubt they would, all the debauchery here seems to be consensual, but you kind of like them leaning on you for a once.

On the boulevard everybody's naked in the late afternoon. You look at the other naked women and notice many ethnicities are represented here - black, asians, some look hispanic, others even look Arab. Nobody tell the Taliban. You figure the men are from a similar array of ethnic backgrounds but with naked women walking the streets, you don't notice the men at all.

"Oh my god people are looking at my private parts!" Katy blathers.

"Well duh, you're naked on the street," you say, and only Heather laughs. You look at Katy's private parts yourself, since you can. She has the smallest tits of your trio of girls, but she's also the skinniest, and with the fittest body from her cheerleading. There is a certain appeal. Like her sister and mother, she has "coin slot" pussy lips. You wonder if that's a genetic trait.

"Hey stop looking at me, pervert," she says.

You shrug. "Come on, let's go to the beach. It's really nice."

You lead the girls down the the beach which is nice and quiet. Just a random evening, you get the impression people prefer to spend evenings in town at the cafes and restaurants. The girls point to a bench off to the side and you take them over there.

"At least nobody can see us here," Ellen says.

"Geeze girl you need to relax," Heather says, "Everybody's naked here. It's not a big deal."

"Well most of them aren't as hot as me," Ellen says, and every but her laughs.

Even Katy joins in. "Geeze you're more stuck up than me!"

You sit with your sisters for a while as the sky goes orange and the sun starts to set across the ocean. An old dude walks by and Ellen covers her boobs and pussy with a "hand bikini".

"Ellen a bunch of people already saw your parts, what good is it gonna do now?" you say with a smirk. It is occurring to you that your sisters need you now to protect them from this place they seem to fear so much. You no longer have to kiss their asses and fear their tempers. You can say what you want.

"Asshole," she says, but sure enough she stays with you there on the bench. You look at her firm tits with those big silver dollar nipples, not even trying to hide your gaze. Ellen has been the meanest to you of your sisters, almost as bad as mom. Looking at her tits, you'd like to...

"Ew he's getting a boner!" Katy says. And sure enough, you're getting hard looking at Ellen's tits.

"Can't be helped," you say nonchalantly. "Go ahead and take care of it for me Heather."

Heather grins at you. Your sisters look aghast. "No way! We're right here!" Ellen yells, mortified.

Katy says nothing though. She's looking at your cock, up to its full ten inches. "It's so big..." your virginal sister says. You stroke it proudly as Heather wobbles to her knees on the sand. "I mean, you pervert!" Katy says, catching herself.

"You girls can just walk home if you don't like it," you say. You remember all the times they made you sit in boredom at the mall while they shopped for hours, telling you that you could walk home if you didn't like it. Yeah, walk ten miles with no sidewalks in the oppressive summer heat. It felt good to throw that back at them finally.

"Is that a big dick then Heather? You're the expert," Ellen says condescendingly. "I wouldn't know."

"Geeze are you 25 and a virgin? That's sad," Heather says and your big sister looks daggers at her. "Yeah it's real big though."

Heather leans in and takes your cockhead in her mouth casually. Nobody but your sisters is around, and Heather doesn't hesitate to suck your dick in front of them on a bench. You really like her slutty attitude, as long as she's just being your slut. Who cares about her past? That doesn't make the super-casual blowjobs any less orgasmic.

You look at her big tits as she leans in, taking your cock down her throat. You are shocked by how fast she's doing this but then you realize she's trying to show off her cocksucking skills for your sisters. That's okay with you. But can she really deepthroat ten inches?

Heather keeps going, forcing her face down on your cock as if this is a fun challenge. She gags slightly as her lips slide along your shaft. You groan in pleasure, the fact that your sisters are watching with a mixture of revulsion and fascination only making this feel better for you. You feel Heather's throat around your cock and then her full lips are pressing against the base of your shaft. This girl took your whole ten inches like it was a delight!

"What a slut," your big sister scoffs.

"Can you do that Ellen?" Katy asks.

"Of course not!"

You laugh. Heather comes up for air, gasping with some drool sliding down her chin and dripping into her big tits. Your cock is so big it made a true slut gag. Too horny to stop now, you reach forward and grab Heather's handy blond hair, guiding her back to your dick. She doesn't resist at all, letting you pull her head down on your shaft.

"Pig!" Ellen said, "Don't make a girl do that!"

"Not like she is opposed," Katy says with a smirk. You're intrigued by how your little sister seems into this now, not sickened like she's supposed to be, and is watching excitedly as you tug at your girlfriend's hair, guiding her to take your ten inches down her hot throat again.

You groan and let go of her hair as Heather takes over, sucking you eagerly on her own, picking up on how much you like the deepthroating and forcing your cock halfway down her neck each thrust. This causes her to make lovely slurping sounds "Gluk gluk gluk" as she rapidly sucks your ten inches. Drool slops out onto her chin and falls onto her big tits, making her look all the sluttier.

You're about to cum so you pull her head back momentarily. "Lick my balls," you command. A fun way to buy some time, right?

"Ewwww," Katy says, but she sounds more excited than grossed out as Heather dives right in to fulfill your nasty request. Your balls are so big she can only take one at a time, dropping them into her mouth and sucking hard and shamelessly. You whack your cock against her face for fun as she sucks on your balls. You've never had your balls sucked but this is amazing, she's putting suction on each one but there's no pain at all, just perverse pleasure as this wonderful slut sucks on your balls in public with your sisters watch.

You stand up now and hold Heather by her hair. Might as well face-fuck her like you're in a porno, when will you ever have this chance again? You might wake up any moment and realize this was all a wonderful dream.

"I want to fuck your mouth like your pussy, slut," you say, "open!"

Rather than be offended, Heather opens her mouth wide and looks up at you excitedly. Her fingers fly to her clit and she masturbates in anticipation. She's actually into being treated like a shameless porno star?

You can't hold back, pressing your cock into her mouth hard. She leans forward, sliding her tongue on your cock as you shove it down her throat. You face-fuck her hard now, knowing you won't last long, playing those nasty notes on her slutty throat again. "Gluk gluk gluk gluk," she sings as slobber pours out of her mouth now. But she's masturbating hard.

You pull out as you cum, wanting your sisters to see this. Even Ellen isn't pretending to not be interested as a massive rope of cum shoots out of her brother's cock onto Heather's face. Heather moans loudly, cumming herself as you paint her face with sperm. So much white stuff is coming out, you must have been really horny. Heather takes it all eagerly with her mouth wide open. You cover her cheeks and forehead with sperm then let the last ropes shoot right into her mouth. By the end it looks like she's taken bukkake from five guys or so but it's just your ejaculate. She starts swallowing your cum without hesitation.

"So nasty," Ellen says.

Heather swallows hard and catches her breath. "Your brother's cum tastes great," she says, starting to lick her face clean, "Best sperm I've ever eaten. You girls should try it."

Both sisters scream at her that she's a filthy slut. She looks to you with concern, not about your sisters, but about what you think of her performance.

"You're my beautiful slut now," you say, "Don't be ashamed."

"I'm not," she says with a delighted smile, then shoves some more of your sperm into her mouth.

Wow, this took forever. CHYOA ate my entire first draft so I had to rewrite from scratch, that really killed my momentum. And this whole thing is a lot more difficult to write than I thought it would be. Oh well, maybe I'll be able to write faster now.
