Fun at the beach

It's supposed to be your day off but you sure have a lot to do. Ellen goes to shower and your stomach is grumbling. You should have made her cook you lunch... but surely a handjob from your big sister is plenty to get in one day. You see a note on the kitchen sink: "Faucet is leaking. Fix. Mom." Ah you feel like you're at home again with passive-aggressive notes ordering you to do chores. As you put in a washer to stop the drip, the only real difference from your boring old life is that you're naked now.

You play some video games in your room hoping Ellen comes by, but she stays in her room with the door closed. Maybe you should talk to her, but what the heck do you say? She's your big sister, it's not your job to be her psychiatrist. She's probably busy with some work project anyway since she keeps irregular hours, and she hates being interrupted.

Eventually it's almost five so you head to the restaurant to pick up Katy and Heather. You're really enjoying walking around naked. You ignore the naked dudes as best you can but you don't think you'll ever get tired of seeing naked ladies in public. Sure the girls your age are nice but it's interesting to see women of all ages naked. Having sex with Ruth has given you an appreciation for women "of a certain age". It's so wild to see a woman's breasts and pussy right out there in public, of course she gets to see your dick in return so it's all fair. In fact you love it when you catch a woman's eyes sliding over your crotch.

You wonder about hooking up with some of these women. You've seen a few looking at your dick, you certainly are better hung than most guys here in your biased opinion, but when you try to catch a woman in the act she's always looked away. Anyway you're not even sure your girlfriend and little sister would be okay with you having sex with ladies other than Ruth. But it sure would be nice.

That morning, you promised your big sister you wouldn't tell anyone she gave you a handjob. It seemed reasonable at the time but now you realize your promise means you can't even tell Heather and Katy about it. You know they'd keep the secret, but you promised Ellen you wouldn't tell anyone. You hate to keep secrets from your girlfriends, but you've painted yourself into a corner here. You'll have to convince Ellen she can trust them.

You pick the girls up from Ruth's, where they have their tips in Katy's purse. Heather doesn't bother with a purse, apparently. She's told you she's kept money in a plastic bag in her pussy before... that's so weird, but kind of hot in a perverse way. Actually few women here seem to use purses and your sister seems out of place with one. This town is so weird.

"So where to?" you ask.

"The beach I guess," Katy says, "I need to relax. Work is so stressful."

"You don't even take orders or carry out food," Heather teases her gently, "You've got the primo job in the whole restaurant, girlie. You're a hostess."

"Katy is what we call a princess," you say, joining in on the teasing.

"I'm not a princess! It's just hard to be pleasant to losers who are thinking about fucking you, and their wives and girlfriends who are jealous of your perfect body," Katy says.

"You're not exactly disproving the idea that you're a princess," Heather jokes, and Katy punches her arm. It's all lighthearted banter though. You're glad that your girlfriends get along so well.

One benefit of walking around naked is you don't have to do much prep to head to the beach. You walk straight there with the girls, buying a bottle of suntan lotion at the last shop where the town ends and the beach begins. This place doesn't even have a boardwalk, the sidewalk just dumps out onto the beach.

Your little sister's haughty attitude isn't exactly upsetting you, but it is a strange contrast to the submission she's shown you when you push even slightly. "Let's go to the more private area," you say.

"You mean the rocks?" Katy whines. You can't enjoy the beach if you're crammed with randos into the small sandy portion, so you insist.

"Yes, the rocks," you say, "And don't be so stubborn, girl. You do want to be my girlfriend, right? You need to obey me."

Heather gasps at your abruptness, but you say it confidently. Still, you think maybe this is gone too far. What's the difference between being dominant and just being an asshole?

"I'm sorry," your little sister says, "Sir."

You've got half a boner just from her calling you 'sir'. From such a perpetual brat who used to delight in disobeying you, this submission is incredible. But you feel like you've earned it by discovering the way your sister enjoys being treated, and now you have the responsibility to take care of her.

The girls follow you into the rocks. You like it better over here anyway. Laying in the sandy, safe beach 20 steps from the pavement is for boring people. The rocky area is exciting and adventurous, you have to scramble up and down to find ways around the chaotic sandstone formations. You all are in good physical shape and can navigate the area with only a little trouble.

Eventually you're halfway around the bay, far from the people on the town beach, and find a secluded area in the rocks with a view of the ocean and a bench-like boulder to sit on once you spread out a towel from Katy's purse.

"Put lotion on us," you say to Katy, "Heather first."

Heather is happy to be attended to be a woman. You are pretty sure most women have treated her like dirt for being a slut. Katy doesn't even hesitate and begins spreading the lotion on your girlfriend. Heather is naked so Katy gets the lotion everywhere, rubbing her tits first in a fashion that seems to be intended more to arouse you and Heather more than apply the lotion in any sort of efficient way.

Heather moans casually as your sister rubs her tits, then works her way down between her legs. Heather spreads her thighs immodestly and Katy has **** but to put lotion on Heather's pubic mound and labia lips. Your sister's tiny fingers work diligently to lotion your girlfriend's cunt. Heather turns around and Katy rubs her legs and back, shoulders, then finally her butt. With Heather's wonderful lack of any shame, she spreads her asshole, displaying her hairless butthole to you and your sister. Heather seems to enjoy this kind of thing, and you fully approve.

Katy blushes. "Kiss my girlfriend's asshole," you command, horny as hell.

You halfway say it just to break the spell and make Katy say some obnoxious insult, but instead she closes her eyes and leans forward. Her lips extend and vanish into Heather's crack, and you hear the smacking sound of your sister kissing your girlfriends butthole. You stroke your dick casually, watching the lesbian analingus as best you can.

"Yess lick my asshole," Heather says. Your girlfriend is as perverted as you are and that's wonderful. She especially seems to like anal play. "Kiss it. Press your tongue inside."

Katy moans as she has her ass licked for what has to be the first time, unless those cheerleader lesbian sessions were even kinkier than you thought. You're fully hard from the thought of that, and of course seeing your sister moan in pleasure as your girlfriend eats her ass. You lean in to look closer and Heather isn't faking this at all (not that she ever would) she's licking Katy's asshole eagerly. You stroke yourself and realize you're close to coming already.

You've got to get in this action while you still can.

"Okay stop licking ass, lezzies, turn around and face your master," you say. Both girls look surprised at your words, which are a lot more stern than your usual nice-guy attitude, but they stand up and blush, without a word of objection between the two of them. Is it possible it turns them on to be controlled as much as it turns you on to use them as your real-life lesbian porn simulator?

You glance around quickly. You hiked pretty far back in the rocks, which block visibility, and the rock field goes on for what seems like forever. No one is likely to stumble upon you back here, unless they followed you. This should be private enough for your purposes, probably safer than your bedroom at home really, with Mom and Ellen never respecting your privacy.

But what to do? You have your sister's tight cheerleader body and her ****-crazed mind, and Heather's big tits and rampant sluttiness. How to have the most fun possible here?

"Heather, I want you to teach my sister how to deepthroat. Don't you girls both agree a submissive should know how to do that for her master?"

The girls blush but don't balk at you treating them this way. It doesn't feel mean to you, they are both your girlfriends, they're clearly into this, so why not?

"Yes," Katy says, "I should learn to take all of your ten inches down my throat, master. It will be hard, but I'll make myself do it."

"It's already hard," Heather says, pointing your dick, and you all laugh at her dumb joke. The way Katy sounded scared of taking your cock down her throat but agreed to it anyway turns you on even more.

Heather drops to her knees on the coarse sand below. Katy does the same, but kneels to your side to watch for now. "Okay, deepthroating isn't that tough," Heather explains like the world's most perverted schoolteacher, "It helps if you're horny, and the guy lets you take it at your own pace. Not all guys will but your brother should for now."

You nod.

"You mostly want to relax and let it go into your throat without panicking," Heather says, "Like this!"

She leans forward and takes your hard-on into her mouth. You like it a little rougher, but for demonstration purposes you let Heather do all of the work. Free of your perverted thrusting, Heather pushes forward easily and your cockhead breaches her throat without much resistance. You groan in pleasure as you feel her throat around your shaft now. You can't resist stepping forward slightly to bury your cock inside this wonderful woman's windpipe.

Far from offended, Heather takes your cock all the way until her lips are pressing against your trimmed pubic hair. You feel her tongue on your balls, licking your nuts despite the ten inches of cock rammed down her throat.

"Show off," your sister says, kneeling to watch, but you can hear the awe in her voice.

Heather tickles your balls for a few more moments then pulls back with a loud slurping sound as your cock is dislodged from her throat. Long ropes of saliva run from her lips to your cock as she pulls back and grasps for air, and some of the drool has already made its way to her chin.

"So fucking hot," you say. A few weeks ago you'd been jerking off to porn of girls doing this... now you have a girlfriend who's better at it than any of those porn stars.

"I want to do that for you too, Master," Katy says, looking up at you as she kneels by Heather. Her voice is soft and submissive. You wish you could take all the credit for this transformation in your formerly bitch little sister, but it's obvious she's a natural submissive and you've merely awakened it in her. Still, it's hot as hell.

You grin and turn slightly, letting your cock slap against Katy's lips. "Open your mouth," you command, and your little sister instantly complies. You press your cock into her mouth and feel her tongue on your shaft instantly. She takes the first few inches on her own but you want so much more now. You poke your cockhead against Katy's throat and instantly she gags, making a nasty guttural sound. She's so obviously less skilled than Heather, but a girl who needs to learn (or be taught) how to swallow your whole cock has an appeal of its own.

You poke her throat a few more times and she almost wretches, making quite the nasty sound with each jab. Drool is pouring out of her mouth from your ****, dribbling down her chin and onto her modestly sized tits. This is something you love seeing in porn so you can't resist jabbing at her throat again and again, making those nasty sounds as she struggles mightily to not puke. You don't want to take it that far, but going right up to it is hot as hell.

Thinking only of your own pleasure, you grab Katy's head to hold it in place and control how much cock she takes. You **** your dick a few inches into her throat, feeling her heave roughly and hearing that wild sound from her mouth as she almost loses it, then pull back to give her just a little relief. Her makeup is badly messed up now and droop is flowing freely.

Suddenly you worry you're taking it too far but look down and she's frigging her clit with her fingers. Since you paused for a moment, she thrusts hre head forward, impaling herself on your cock, taking you the deepest yet, with perhaps seven inches **** down her throat before she jerks back, gasping for air with spittle flying everywhere. She moans softly as she masturbates. It's actually turning your sister on to get abused like this? You think that's the sexiest thing you've experienced yet on this island.

You thrust your cock back into her mouth, getting as close to face fucking her as the formerly innocent girl can handle, making that guttural sound on her throat with most of your thrusts. She looks up at you submissively, involuntarily crying from the **** exertion.

You groan in delight but pull out at the last moment. "You don't get to make your Master cum until you can fully deepthroat me," you say. So cruel, and yet, she looks at you with those submissive eyes and masturbates all the harder.

"Yes Master," she says, "I will practice until I'm your proper submissive girlfriend."

You turn to Heather. Your cock is covered with your sister's slimy drool but Heather opens her mouth instantly and you give her a true face fucking, shoving your cock all the way down her throat hard. You thrust against Heather's face hard enough to make the veteran cocksucker's throat make some nasty sounds, and slap your balls against her chin.

You can't last long after the submissive blowjob from your sister and finishing up in Heather's perfect mouth. You explode ropes of cum in Heather's mouth, completely filling it with your sperm as she tilts her head back and opens her mouth as wide as possible, eager to let you jizz into her mouth.

You're still horny after all of that, somehow. It sure helps that both girls are openly masturbating now, even though you were just thinking of your own pleasure, they loved the way you treated them.

"Okay ladies," you say, sitting down on a rock to rest, "You both get my cum. But I want to see you have fun with it before you swallow your share."

It's such a perverted request, obviously for your own pleasure. But your little sister's face lights up with excitement when you say it, and her fingers on her clit start to move faster.
