To the beach!

And so, here you are. Sun is shining high in the clear sky, the warm, humid breeze beads your bare skin with sweat, sounds of people splashing and laughing spread around like the background of a summer song. To be ahead of the sea season, the place is quite crowded. You take a deep breath, the light fabric of the shirt tickles your inflating chest; for the rest, you're wearing only your trunks and sandals.

Your thoughts are still focused on the lessons you're losing right now, but they are abruptly wiped out by a high-pitched screech.

-Yahtzee!!!- Your younger sister surpasses you running and wheels around, teasing you with her red bikini by pulling the straps on the sides of the bottom.

-Big Bro, Big Bro! Let's take a swim!-.

She is undoubtedly the most enthusiastic, even more than your mother: throughout the entire drive, she did nothing but giggle and squeal, and when you arrived at the hotel she immediately rushed to see the rooms. She had remained a bit puzzled when Mom informed her that she would have slept with Kim, while you would have been alone; but then she added that your room had a double bed, and immediately her joy returned. Yours... kind of.

-Don't start like this.- Growled your other sibling's voice. As with Tina, you hold your breath seeing her in her pea-green, double-piece swimsuit, although her bosom is undoubtedly more modest. She's busy taking off her shorts, and looks at you with a "deal with it" face.

-Come on Kim, we're going to have so much fun together!- Tina runs to hug her, but she sharply pushes her away.

-Nope, we're going to have so much fun alone. Listen up. First rule: don't bother me, never, for any reason. Other first rule: if you splash me, I break your teeth. Other other first rule: shade is mine, dot. Second rule: repeat the firsts. Got it?-.

Tina blows through clenched teeth: -Pff! What a curmudgeon! Just imagine what we could do, the three of us together!-.

-Indeed. No thanks. Now, if you'll excuse me...- She heads for your seat, having your parents have already planted the beach umbrella. Tina snorts in frustration, and you put a hand on her shoulder.

-Hey, you know her.-.

-Urgh... you're right!- Without any warning she clings to you, pressing her boobs against your body and peeking at you with puppy eyes: -It means that I have you all to myself!-.

-W-Well...-.

-Hello, lovebirds.- Giggles your mother's voice. You turn around and...

Holy crap.

-Your father and I are going for a walk.- She announces from behind her large sunglasses. Her hair is tied up in a bun and she's wearing a tight, zebra-striped bikini which doesn't leave much for the imagination. With the tail of the eye, you see that Tina looks transfixed too for a second.

-Please, behave yourself...- She flashes a sly grin that is immediately reciprocated by your sister.

-Of course, Ms. Harris.- Uh? -Have a good time.-.

-Thank you, dear. Bye, sweetie.- She turns around and walks away, but Tina doesn't let you admire her swaying bootie as she's again rubbing your chest.

-So, so, could you put some sunscreen on me? My poor skin needs all the protection those big hands of yours can give!- She pouts, but you can see the hint of a grin curving her lips. It was just a matter of time, after all, and now your boner is pressing between her legs.

-Hold on, Tina, what are you doing?- You ask, looking around to make sure no one is watching you. As it's obvious, it's not that you're not appreciating this, but it's all too much... explicit.

-Mh? What's wrong?-.

-There are people here!- You protest, and she has the coveted epiphany. Only that she laughs about it.

-Yep, so? There are too many people to notice us! Plus... no one knows the truth, right?-.

"W...What?".

-Don't you see, Tom?- She squeezes herself tighter, her perfumed lips are now only a centimeter from yours.

-All they would see is two young lovers cuddling each other.- She pecks you on your mouth and chuckles, and then pretends to wait for a protest, or some scandalized scream, which doesn't come. As she predicted.

-See? Now, Let's go!- She clings with legs behind your back and arms behind your neck, making you blush (and, of course, snort).

-Take me under our umbrella, Mr. boyfriend!~

---

A whistle coming from behind of you gets your attention. You don't realize it immediately as this has never happened to you before since you're in this body but... it was meant for you?! What a boor, how dared he, whoever he is??? You feel scandalized, embarrassed, and...

Heh.

Horny.

You're strolling around holding your husband's hand, the warm sand foundering under your feet. To your satisfaction, as you pass you attract the aroused gaze of many men, both young and old, and the envious ones of their women. More than once, you hear quarrels erupt behind your back; and now even whistles.

You smirk.

Women like you are... well, rare. So, you reason, it's normal that they have these reactions: poor guys! You feel sorry for them: tonight they'll wank thinking to the impossible booty who has passed under their noses, without even (apparently) so much as look at them. Though, one of two seemed... sufficiently endowed, judging by their costumes.

"Who knows, who knows...".

And while they're checking on you, you, hidden by the lenses, take a look at the women too. Again, women like you are rare, but the local game is all but scanty. Not for yourself, of course: you're a straight, faithful wife and an obsequious mother, like anyone could testify, from your beloved older sister to your sweet, wonderful babies. But you wonder that Tom would appreciate if...

-Damn! I should have brought a hat!- You comment, referring to the hotness you're feeling for walking in the sun. You turn to Robert, who agrees with a smug that tastes more like courtesy. You feel a bit bad as you scrutinize his glassy gaze (though, unless someone really pays attention to it, they wouldn't notice it): it's like the little piece of you was enough to obscure his soul, and now he's slipping into the everyday routine without really feeling it, like a shadow. Well, maybe you're exaggerating a bit: right now he is in one of his worst moments, he's not always this dull. But again, he was your father and now he's your husband, it hurts to see him like this.

-Poor hubby!- You comment, smacking him on his cheek. The least you can do is to be a caring good wifey, right?

By now, men's glances have become invidious. You know what they're thinking about: Robert is good-looking, but not above average, so how could someone like him have married someone like you?

"What a means! How dare they insult my big teddy bear?".

Women are relieved, instead; "See?" they rejoice: "She's already engaged, forget those boobs and focus back on my plain titties. But tonight you'll sleep on the sofa.". You know what? Those rudes deserve such hideous slobs!

-Those people cannot comprehend, right?- You whisper to your husband's ears, hugging him tenderly.

-What do you mean?-.

Chuckle: -Nothing dear, nothing. Let's find some secluded spot, shall we? I want to remind everyone what it means to be Mrs. Harris~~~-.

---

You deposit your sister on the cot, since Kim, who is currently reading some magazine, has occupied the mat. Tina is sniggering like a girl at Luna Park and then fondles her boobs as she is adjusting her top. You gulp.

-Come on, Tom, put the sunscreen on my hot body!- She exhorts with a mocking smile. You comply, spreading some on your hands and then placing them on her outstretched leg. She makes a fulsome moan and you hesitantly begin to rub upwards, where her flesh gets flaccid.

-Mmm... ohh, you like my thigh, don't you?- Her leg then bends, surging sinuous like a snake, allowing you to massage its back too. You're getting close, real close to the line of her slip. If you'd just move your fingers, only of a bit...

-Hey! Why did you stop?-.

-I need more sunscreen...-.

-A-a-ah.- She stops you before you can squeeze it on your hands again. She stretches the leg and flexes the other one, pointing with the finger to the side of the thigh, just below the infamous joint. The way she's biting her lip is an unequivocal mask of what she's requiring from you. You sprout the lotion on her skin and then...

SPAT

-Kya!- She lets out a high-pointed squeak, to then subsequentially consents to your salacious massage with her familiar chuckles and moans. You pass to her stomach, though she shows grief at your ignoring her groin. You slap another puddle, this time on her abdomen which thus sags like crumb, eliciting another cry of hers. Her tummy is soft, but not soggy, as you feel a layer of toned abs under the skin.

You've never lingered on her belly so much, but now that you see that little hole swelling and deflating according to her breathing, you feel like it's craving you to kiss it, heedless of her protesting laughter that would ensue.

-Mmm... you're so sweet, Tom.- She purrs, holding your hand and thereby interrupting your flow.

-But... I feel you're forgetting something...- She guides it over her top piece, where your fingers instinctively take a firm hold.

-T-Tina, we can't...-.

-Ssh! Don't be noisy, or they'll catch us! Be quick!- She dismisses your objections and doesn't wait for your consent: your hand gets slipped under her cloth, meeting the fluffy tissue you've come to love from experience.

-Yes... go on, big bro... my skin there is so sensitive... please help me not to get scalded... I need your full protection...~.

Full... protection?

You look at your other hand, trembling, still smeared with cream. You slip it under the other cup, starting to grope your sister's tits, right there, in the middle of a public beach, with her nipples prickling in the center of your palms. Her face flushes conspicuously and she looks at you with fire in her eyes. No one is noticing anything, no one is saying anything. No one will intervene...

-Kids.- Kim blatantly warns you, turning the page. You startle as you hear someone coming running, and you immediately retreat. Behind you, three children hurrily pass on, steering for the water.

-That was close...- You say, your heart beating fast both in excitement and fear.

-Uh-uh. Well, your turn now!- Tina jumps up and gestures for you to take her place. You're still not very sure of this, plus her back is still uncovered; but, judging that it's better not to remind her, you comply. As soon as lie down, she straddles you and props her crotch only a spit above yours.

-T-Tina!-.

-You do like my name, huh?-.

She seems totally neglectful of the danger just passed and she immediately aims for the nipples, pinching and twisting them with her sticky fingers. You are already dripping in sweat, but now you feel it falling from your forehead like spring water. Oh Jesus, why are they so sensitive? Is it normal? You manage to stifle any noise, even if your clasped hard-on is already pressing on her clad, tight, buttcheeks. She works on your chest with thorough dedication, and after a minute she finally leaps on her feet to move to your legs. Apparently, the more she goes on and the more she focuses on her non-perverted-one task, maybe because your hairy limbs aren't actually an erogenous zone. Probably it's for the best, you reason, you've already pressed your luck, and not even Tina is so reckless.

So you jolt with surprise when she swiftly sneaks her hands in the shanks of your boxer to grab your stiffened dick from both sides. You open your mouth, but instead of words only a damped groan comes out. Your sister licks her lips, stroking hard your cock with a crazy look in her eyes.

-Sss...ssstop...-.

-Why so? I just need... more lotion... from the tube...- She raves increasing her speed.

FAP FAP FAP

"F...Fuck!".

-Mmm... yeah, come out, come to your little 'sis...-.

-Will you ever shut up??-.

Much to your relief but also frustration, Tina halts instantly, taken aback by Kim's sudden outburst. Your elder sister has closed her magazine in a rough motion, and she's fuming from her ears.

-I'm trying to read, you know?-.

You're still confused by the sudden interruption, Tina instead recovers sooner and puts her hands on her hips: -Well, excuse me! Just go elsewhere!-.

-Ah-ah.- She shakes her head: -Remember first rule? "Shade is mine" and "don't bother me". So you are the ones who should leave.-.

Tina's expression is left dangling mouth, but then contracts into an angry grimace: -Listen here you-

-Or you can make yourself useful, and spread the sunscreen on me too.- Kim totally overlooks her with a perfect, plain face.

-W-What? Why on earth should I-

-Ok then. Tom, dear, would you be so kind?-.

-I'm doing it!- Tina seizes the tube and Kims rolls prone. Your sister's mouth is still writhing in irritation, thus rather than massaging her skin she seems to want to knead bread. You observe them, unable to mutter a word. You should probably do something, say something, move, but you know that Kim would shut you down without any regard.

-Slower! Gentler! Come on Tina, it's not that difficult!-.

Tina excels herself in patience, and in a minute-a minute and half she's done, without any other complaints. Well, minus the final: -Snappy, but at least no more than I've expected.-.

-Grrrrr...-.

What the hell is going on? What's gotten into Kim, is she trying to snap her out? You feel caught between two fires: the well-known, hideous bitchiness of Kim on one side, and the rarely achieved, then potentially very dangerous, Tina's fury on the other. Tina had expectations for this vacation, you recall, and Kim is spoiling them with her attitude, which is even worse than usual.

-Oh, and one last thing. Stop messing around with my boyfriend, lovey.-.

Tina freezes in place, even if it's like 27°C out there.

-Your...!-.

-Why, of course.- Kim calmly stands up, staring at her sister in a pompous coolness.

-I mean, it's obvious that the role of the girlfriend is up to me. Don't be that frustrated, it's not your fault. You can be my DUFF, still: I'm sure we'll find you some boy with passable standards for this week...-.

-You know why you can't be the girlfriend?- Tina retorts with a tic on her eye: -Because with your personality you'd be ditched in no time!-.

-What?! I'm the nicest person on the earth!-.

-Girls!- You draw their attention, fearing that someone might hear their shrieks: -Please, don't fret!-. In your wildest fantasies, actually, this is something you've always wished for: your sisters arguing about being your girl with the same passion and causality with which they would fight over a nice pair of shoes. If Tina would have been interested in shoes, but's that's not the point. But now that it's really happening... well, it's not really as you've dreamed.

-I'm perfectly calm! And I will be even more as soon as we kick off this drag and we get back to have fun!-.

-Umpf! In your dreams, maybe. Look, I honestly didn't want to come to this, but you're lacking everything to be a good girlfriend. You're petulant; childish; fat; and you're not even a decent kisser.- Kim retorts spitting acid with each adjective.

A part of you would like to answer that it is not true at all (except maybe for the childish part), but you understand that it would only feed the flames. Which is something they're already good at.

-Pff! Please! I'm waaaay a better kisser than you!-.

-Oh, yeah?-.

-Yeah! You know, I bet I'd last a lot longer than you!-.

Kim opens her mouth to reply, but she doesn't. If you start to have any hope that the conversation is over, you soon find out you are wrong.

-Fine then. Let's settle this out.-.

-Hah! And the winner plays the girlfriend!-.

-Urgh... dealt.-.

Wait wait wait! Do they mean to... here? Now???

-Hold on girls, do I have a say on this?-.

-No!-.

Well, at least they agree on something. Kim sighs heavily, and asks you to bring her a bottle of water. Why? To rinse off later, of course. Tina parrots her in irritation, but then they fall silent and their glances become deadly serious. They move closer to each other, until their bodies are almost touching. Kim skims her sister's cheek, who tilts her head in response. Oh shit, they're really gonna to-

"!!!".

Your two sisters have locked their lips, both their eyes closed and their breathing withheld. Your penis twitches at that sight and your heart crawls up your throat. They were insulting until a moment ago, and now they're making out like newlyweds. It's so hot.

Their mouths close a few times, each savoring the other's flavor. One of them, or maybe both, emits a muffled, high-pitched moan.

-G-Girls...-.

Their reciprocation grows intense, Kim's hand shifts behind Tina's nape while she girds her hips. Their maws open wider and wider as if to swallow the other, before going back to being just splint, and hence starting over.

-Can you hear me?-.

Tina sits down on the cot, right next to you, your sister follows her without breaking the effusion, or losing pace in the slightest. On the contrary.

You look at your right. At your left. By some miracle, no bathers have yet noticed this incestuous snot, even if its lesbian nature would be enough for many of them. And you definitely still feel horny by Tina's unfinished handjob.

Throwing away any precaution, standing here like a stockfish, you begin to rub your member across the trunks, while admiring your two sisters, totally oblivious of their previous wrangle, as they leave behind every inhibition, forgetting everything else in the world who is not the other.

---

A smirk paints on your face, your eyes closed.

"Good girls. You're making mommy proud.".

-Aww!!!~~

You shut your eyes open and finally get to cum, to then cling to the steady body of your husband which is keeping you pressed against the wall of the stall. You love that lustful contact, that lewd intimacy. A drop of semen drips down from your womanhood, although it's still penetrated by his cock, and stains your costume which you discarded as soon as you've entered the stall. Oops.

-Babe, you've been great.- Robert pants, his strong hands gripping your womanly hips.

-Thank you, dear. You still know how to make me cum like a schoolgirl.- You hug him and close your eyes again, focusing back on your other body. The woman who has put her umbrella next to yours undoubtedly won't enjoy the same benefits, since both she and her now-controlled husband are chubby and withered. You can't wait to get out of her. The situation is obviously temporary, you just have to make sure that someone more, er, pleasing, takes their place: after all, you can't allow your little Tom to be surrounded by old rackets, can you? Though, with all the enthusiasm from your daughters, the sensation of such an aged body being aroused in spite of menopause doesn't make the passage of time more manageable; not that the other clones (which you've placed coming earlier on the beach) had better luck, except for a one of two which you'll keep.

You cut off the link, having ensured that everything is indeed fine, and even more than fine, and you break off the embrace. You sniff. Gosh, now you're dirty with Robert's sweat. A bath is a must.

---

-Uff!- Kim lays down on the cot, more exhausted than she would like to lead to believe.

-I guess it's a draw.-.

-Uh-uh.- Tina nods and gets up, leaning her ass right over your boner. You struggle to keep yourself from ripping off her bikini and throwing her on the spot.

-You know 'sis, I think I'm ok with sharing. Besides, an open relationship is a norm nowadays, right?- She proposes while she kills you with her twerk. Surely they have stopped at the same time, but she seems to have much more energy left; Kim shields her forehead with her wrist and answers: -Fine, I suppose it's acceptable.-.

-Yayyyy!!! Girlfriends forever!!!- Tina sling on her older sister, making the cot tremble badly. You've left again with a raging erection sprouting and no physical satisfaction, except for the scenery.

-What the fuck?! Stupid bitch, get off me, I'm fucking melting!- Sensing the exact opposite, Tina adheres completely to Kim's body, happily rubbing onto her just like a purring cat. You're still not sure if this new behavior of her, so energetic and reckless, so dramatically different from her past serious self, is merely a facade or not; but damn, it's hot. Kim is not of the same opinion, well, actually she finds it hot too yet in another meaning; but after a bit of struggling she rests her head, having eventually capitulated.

You must have stared too much, since she eyes you with a dagger.

-What are you looking at, moron? Help me!-.

You take a step obediently, but then you stop. She's confused, and then aghast by your grin.

-Of course, dear girlfriend. But only after a bath; now, I'll bring you too, but you don't want to be bothered, to be splashed, or to be out of the shade. First rule. Thus, have your fun alone, and see you later.- You wheel and walk away, laughing at the curses she's throwing to you.

-What the hell! Come back immediately! I'll dump you, understood? Dump you!!!-.
