The Best Vacation Ever

byJunichiro©

Hot. Sweaty. Sticky. It's funny how words can take on such different meanings depending on context. For instance, given the venue, you probably think those are meant to describe some midnight tryst; "hot" might describe the encounter itself, "sweaty" the participants, and "sticky" the, er... results.

But no, sadly. They actually describe an environment, specifically that of my bedroom in a quiet Baltimore suburb on the night of August tenth. "Sweaty" refers to me, of course. "Sticky" refers to my sheets, but not in a good way. Also the air, so choked with humidity that it was hard to even breathe. "Hot" refers to... well everything, really. I don't know if you've ever been to inland Maryland in the summertime, but it's miserable. Add to that the fact that we were in the midst of a heat wave, and the fact that the one window air conditioner in our house was currently working its magic in my parents' room and you have a situation that's just plain hellish.

There was a silver lining this time, though; I was leaving for vacation tomorrow. A relaxing three days at the shore with my family sounded pretty good right now, I have to say. Oh, I guess introductions are in order. I was going with my parents, both in their late forties, and my sisters. My older sister, Amber, was twenty-four and worked for a living, but still came on vacations with us. Kelly, my younger sister, was eighteen and just out of high school. At twenty, I was in the middle. My name is Mark.

Anyway, these were my thoughts as I lay in bed, staring at the ceiling on that hot August night. I calmed down and relaxed into my bed, imagining the cool ocean breeze on my face. I could almost feel the waves washing over me as I rolled onto my side and drifted off to sleep.

"Mark!"

I groaned.

"Mark, come on, get up! It's time to go!"

I slowly managed to open one eye, the other jammed firmly into my pillow. It was Kelly, still in her pajamas. I groaned again.

"Mark! Come on, we have to go!"

"Ok," I mumbled. "I'll be down in five minutes."

"Ok, but don't go back to sleep!" With that, she flitted out of my room as suddenly as she'd appeared. As she did, I couldn't help but notice how nice her pert young ass looked under the thin cotton of her pajama pants.

---

I slept most of the way there, After we arrived and unpacked, my parents wanted to take a nap, and my sisters wanted to go to the beach. I was tired, but they dragged me along with them. I made a show of pouting, but it was all in good fun. When we got there, they immediately ran to the ocean while I set up the umbrella and two beach chairs we'd brought along. I sat in one of the chairs, content for now to take in the sights: the clear blue sky, the green-blue water shimmering in the sunlight... my sisters.

They were a vision, frolicking in the water together. Amber was a knockout who didn't know it, a tall, leggy redhead whose curvy thighs flowed into a perfect round ass, and who had a pair of large, round breasts that never failed to attract attention. Her thick-framed glasses gave her a sexy nerd look that completed the package incredibly. As she swam and played in the water, her enormous tits bounced and swayed, straining against the wet fabric of her top, her nipple pointing through them from the cold water.

My younger sister, Kelly, was just as hot, but in a completely different way. She was a shorter-than-average brunette with freckles, a tight, sexy ass, and very small, perky tits that were every bit as enticing as her sister's huge ones. As I watched them play together, my mind ran through all of the things I wanted to do to them, or wanted them to do to each other. I guess I should say that I'd never thought of my sisters that way before, but I had; how could I not, a growing boy with two of the hottest women he'd ever seen prancing around in his own house? I'd been fantasizing about Amber for as long as I could remember, and while Kelly was a more recent player in my fantasies on account of her being younger than I was, my thoughts of her were no less dirty. That moment, I was picturing a scene in which she was lying on her bed at--

"Mark! Hey!"

I started. It was Kelly.

"Sorry, what?"

"Spacing out much? I said Amber wanted me to send you out to her. I'll watch this stuff."

"Oh, ok. Thanks."

Concealing my erection as best I could, I jogged out to the ocean and found Amber chest-deep in the waves, just past the breakers. Each swell in the water level lifted her heavy breasts and forced them together just slightly. It was difficult to stop my leering from being too obvious.

"Hey!" Amber shouted, giving me a hug and crushing those giant tits against my chest. "How's it going?"

"Good, good. How about you?"

"Ah, good, you know. Can't complain. I've missed you guys."

"Come on, it hasn't been that long. When was the last time you came by, three or four weeks ago?"

"Yeah, but I get lonely."

"So I guess that means there's still not a man in your life."

She grinned. "Just you, little bro."

I chuckled. I really did love Amber. We'd always been close, partly because she used to look after me while our parents were at work, and partly because she was so unbelievably hot that I couldn't ever seem to take my eyes off of her, but mainly we were just great friends.

We swam and splashed and messed around while we talked. At one point I was standing facing the shore, and she was looking back at me.

"Don't move," she said.

"Wha--" I started, then felt a huge wave push me over from behind. For a split second, I was angry, but in the next instant something happened. As I was flailing my arms underwater, I felt my hand land on something curved and firm. Time itself seemed to slow down as I realized that it was my sister's breast, which had been the object of my desire for so long. I savored it as best I could as my hand ran along it, brushing over her hard nipple, depressing the flesh of her tit ever-so-slightly. And then, as fast as it had happened, I was dragged away, toward the shore. The whole thing couldn't have taken more than half a second, and I don't know if she even noticed. I stood up in a daze and heard her laughing.

"Haha, sorry Mark, I couldn't resist."

"Yeah, yeah... just remember, payback's a bitch."

"Oooh, ok, tough guy. I'll watch out for you then."

"Yeah, you do that," I said lamely, and turned to walk away.

"Where are you going? Aww, you're not mad at me, are you?"

"Huh? Oh, uh, nah, I'm just going in for a bit. I have to go to the bathroom."

---

My parents had rented a suite for themselves and one for us, so I had the place to myself when I got back. Which was good, because I had more in mind than just taking a leak. Between Kelly's tight teen body and Amber's voluptuous curves, I was horny as hell as it was; add in the fact that, however briefly, I had actually managed to touch Amber's breast and I was going out of my mind, and needed relief.

I laid down on the bed with my tube of Vaseline next to me and started to stroke my already-hard dick. As I did, I thought about Amber, first just the way she'd looked, with her giant tits heaving in the water, then the way it had felt when I'd touched her, and finally I got around to thinking about what I'd be doing to her right then if I had my way. My mind rapidly went back and forth between a number of acts I would have loved to carry out with my sister: fucking her face, her tits, her pussy. My thoughts weren't coherent. In the past, I'd often constructed elaborate fantasy scenarios involving one or both of my sisters, but this was not one of them. This time I was acting on raw, animal lust, racing toward relief as fast as possible. I began speaking uncontrollably under my breath.

"Fuck... yes.... oooh fuck yeah your tits are so good... they feel so fucking good wrapped around my cock... oh Amber... oooooh fuck yes..."

Just then I heard footsteps. They were quiet, but I heard them.

"Wh-who's there?" I asked, quickly pulling my bathing suit back on. Slowly, the bedroom door opened and a red-faced Kelly walked in. My cock involuntarily jumped at the sight of her, barely clothed in her bikini and dripping wet.

"H-hey, sorry..." she started. "I just came in to use the bathroom, and... sorry..."

"Oh God. Uh..." I stammered. We both just looked at each other for what felt like hours, neither of us knowing what to say. Finally, she spoke.

"So... what's up?"

I laughed. "not much."

"Well seriously, it's no big deal. Everybody does it."

"I know, I know," I chuckled. "I've been to high school sex ed."

"No, but I mean... you know, I do it."

I gulped, and quickly tried to hide the fact that I found the prospect of Kelly get herself off extremely arousing.

"I... I know."

"Ok then," she said, standing up to leave. "It is forgotten. See you on the beach!" She started to walk out, but paused as she reached the door. "Hey Mark?"

"Yeah?"

"Can I ask you something?"

"Sure."

"Were... were you, uh... were you thinking about Amber?"

Oh shit she heard me. I felt my face turn bright red.

"I mean, not that it's... well who could blame you, right? She's really hot."

"Uh... I... eh..." I stammered. "I guess I... kind of..."

"Oh! God! I'm so sorry, Mark, I shouldn't have said anything, it's just... this is going to sound weird, but I heard you say her name and I got a little... jealous?"

I was shocked. Scandalized. I have no idea what made me say what I said next, but without thinking, I blurted out: "ithinkaboutyoutoo."

"What?"

"I, uh... I think about you too, sometimes."

"Oh," she said, digesting the information calmly, somehow. "Well, ok then. Let me know when you're done. I'll be in the other room."

"W-what?"

"Well like I said, Mark, I do it too. And I guess we might as well be open about it. So let me know when you're done, then I'll come in and take my turn."

I was shell shocked. Done? She thought I was going to just pick up where I left off, as though nothing had happened? I didn't intend to, and I told her so.

"Oh, no way! I'd feel terrible. Mark, come on, please? I won't really wait in the next room if that's what's bothering you, but I'd hate to have cut you off like that."

"Kelly, look... it's... it's just too weird, I think. Just the fact that you'd know I was doing it... nah, much to weird."

"Hmm..." she emoted, bringing a finger up to her lips as she sometimes did when lost in thought. God she looked hot. "I think I know the answer."

"What answer?"

"Well, I'll feel terrible if you don't finish yourself off, but you'll feel awkward if I know you're doing it. So we just... take away the awkwardness."

"And how would you do that?"

"Easy, I'll do it too."

"What? Come on, be serious."

"No, really. Fair's fair."

"So you just go in the other room and do it while I do it in here?"

"Well..."

"Well what?"

"Well I didn't exactly just hear you before?"

"What?"

"I watched you."

"WHAT?"

"Sorry, I'm sorry! I just... well, I heard you from the hall, and I got curious, and I peeked my head in."

"Jesus."

"Hey, hey! It's ok, right? And anyway, you have nothing to be ashamed of."

"Kelly!"

"Well, you don't."

After a few seconds of silence, I spoke. "So what are you proposing?"

"Well, since I watched you before, I think it's only fair that you get a chance to watch me, if you want."

"So we just, what, masturbate in front of each other?"

"Yeah, exactly. No big deal, right?"

"Look, Kelly, I don't know if I can do this, it's just too weird, you know?"

She walked over to me, leaned down, and whispered breathily in my ear. "I'm not taking no for an answer."

As she slowly stood back up, she untied the back of her bikini top, letting it fall to the floor. Her tits were incredibly sexy. She never wore a bra because they were so small, but they looked amazing from where I was sitting. They were just two small lumps of flesh, barely protruding from her chest, and two tiny, erect nipples poking out from them.I admired the gentle curve as her chest turned into her tits, the round underbelly of each of them, the goosebumps caused by a combination of cold and excitement. Perfection.

"I was going to ask you if you liked what you saw, but I guess I have my answer," she said, gesturing at my tented bathing suit as she sat down on the bed opposite mine. "What do you say we get started?" She hooked her thumbs in the sides of her bikini bottoms, then said, "same time." Mindlessly, I pulled off my bathing suit as she slid hers slowly down her shapely legs.

Her pussy was gorgeous. It was very small, and looked incredibly tight. It was shaved, for the sake of her bathing suit, no doubt, making everything nicely visible. She had large pussy lips, two inviting folds of skin framing her tiny hole. At the end of each, droplets of moisture were visible, and it was clear that she was very wet.

"Mmm, you like that, huh?" she asked, gently caressing her lips as she stared into my eyes. "You like my pussy? I can tell you like looking at it. Your cock is really nice too. You want to stroke it for me?"

I had forgotten all about that. I reached down and started to slowly stroke my rock-hard dick.

"Mmm, that's so hot," she cooed. "I'm so wet for you." She dipped a finger into her pussy and brought it out, coated in her juices. "See? Really wet... watching you before got me sooooo horny... do you like watching me?"

I nodded.

"Do you like my little tits?" She slowly rubbed circles of her come onto her nipples, first one, then the other. "I know they're not much, but..."

"I love them."

"Really? I thought you liked Amber's big tits. That's what you were thinking about before, right?"

"Yeah, but I love yours too. I love them both."

"Mmmm, that makes me so happy." She moved her hand back to her pussy and started to rub it from the outside. "So what were you thinking about earlier?"

"Amber."

"I know, but what about her?"

"Different th--"

"Were you thinking about her big tits?"

"Y-yeah." I was jerking off faster now."

"Mmm, I bet," Kelly moaned, as she slid her middle finger into her pussy. Her twat was so tight that it looked like it barely fit. "I bet you think about them a lot, huh?" I nodded. "I bet a lot of guys think about those tits while they jerk off. I bet they think about sucking on them. Fucking them--oooh!--is that what you like to think about? Do you like to imagine yourself sliding that big cock between our sister's tits, and just fucking them?"

"Yeah," I managed. This was too much.

"I bet you think about grabbing them hard while you fuck them. Pinching her nipples while you fuck her tits nice and hard." She was thrusting her finger in and out of her slick cunt now, and her hips were thrusting upward to meet it. I bet you think about coming all over them, right?"

I moaned my approval.

"Mmmm, I thought so. You're a dirty boy, jerking off in here, thinking about covering your own sister's tits with your come. I love it. I love fingering myself for you. I even like the way that word sounds. 'Fingering.' Do you like that? Do you like to hear me talk about fingering my hot cunt while you watch?"

"Y-yeah.. fuuuuck..."

"Mmm, sounds like you're getting close to coming, Mark. Am I turning you on that much? Do you like my little pussy?"

"Nnnngh fuck! Yes!"

"Ooooh I'm so glad. I wanted you to like my pussy, Mark. Fuuuck I wanted you to watch me... and more... god I've wanted this for so long... are you close, baby? Are you close to coming for me? I've been close practically since we s-started, but I've been holding back, so we can come at the same time.... mmm, but fuck, Mark, I want to come so fucking bad. I want to make my tight little pussy come while you shoot your hot come all over it.

I groaned and my cock spasmed. I felt the come rising up in my balls.

"OOoooh fuck I guess you like that idea, huh Mark? You want to shoot that hot come all over this little, tiny, pussy? This hot little teen cunt? Mmm, fuck... do it, baby. I'm going to come... I'm going to make myself come,... ooooh fuck, do it now! Do it now, Mark, fucking come all over my pussy! Shoot that hot load all over this wet c-c-c-CUUUUUUUUUUUUNT!"

She started coming, and I quickly moved over to her bed as I was on the verge of orgasm myself. Kelly was jamming her finger into her tight pussy as hard and fast as she good, her hips were off the bed, and her whole body was shaking. I immediately started pumping come out of my cock and onto her bald teen pussy, coating her lips and fingers right away.

"Oooooh fuck that's it! That's it, baby, fuck I love it! Ooooh fuck yes it feels so good! Your come feels soooooo good on my cunt, baby. Oh that's it, keep jerking off for me, keep shooting that come, give me all of it! Oooh fuck Mark I'm coming so hard! You're making your baby sister come so hard!"

I was still coming, sending rope after rope of thick white seed onto my little sister' pussy mound. She was now pushing it into her pussy as she fucked herself. I could actually see her pussy contracting as she came, squeezing her finger as though it were a tiny dick. When I finally stopped coming, she brought her hand up to her mouth and started licking my come off of it as she fucked herself with her other hand. She rode out her orgasm in this way and then laid there, flushed and panting.

"That was amazing," she said.

"Yeah," I said.

"Don't worry," she said, reading my mind. "This won't be the last time."

---

The sleeping arrangements for the week were these: the suite had a bedroom with two twin beds, along with a pull-out sleeper couch in the living room. We had agreed to take turns sleeping on the couch, and the first night was Kelly's night, which meant that Amber and I had the beds. I, for one, found myself unable to sleep, instead reliving the day's events in my mind and getting myself worked up. I looked over at Amber. She was fast asleep, her big tits rising and falling with her breath. God she was hot. This wasn't helping my hard-on, and I didn't want to jerk off with her right there in the room.

Just then, the door opened, and in walked Kelly, as quietly as she could. She skulked over to my bed.

"Still awake, big bro?" she whispered.

"Yes," I replied.

"Move over."

I obliged her, and she slid into my bed next to me. She was wearing the same cotton pajamas she had been that morning, which I found very sexy for some reason.

"Can't sleep?" she asked.

"Nope."

"Yeah, me neither. I'm just so horny, I can't stand it."

"Yeah, me too."

"Oh good, then we're in agreement." Without warning, she planted her lips on mine and explored me mouth with her tongue, kissing me hard and intensely. As she did, she placed a hand on my chest and started to slide it downward. I broke the kiss and grabbed her hand.

"What are you doing?"

"Don't you want to?"

"Well yeah, but... with Amber right here?"

"Oh please. You'd probably love it if she woke up and caught us."

"Kelly, we--"

She unbuttoned her shirt and took it off, exposing the perfect little tits to me once again. I was powerless to resist, and she knew it. She leaned into my ear as she had earlier.

"I want you to touch me," she said. I brought a hand up to her chest and tentatively began to squeeze one of her breasts. She moaned in my ear and slid her hand further down my body, lingering just above my pelvis. I grew bolder, squeezing her tits harder, going back and forth, kissing her as I did so. As we lapped at each others' tongues, she slid her hand down farther and cupped my balls, gently rolling them in her hand as I lightly pinched and tweaked her nipples.

Suddenly, she removed her hand. I was disappointed and confused at first, but I understood when she used it to grab mine and shove it down her pants. I felt her little pussy in my hand and almost fainted. It was giving off an incredible amount of heat. I felt her oversized lips and gently rubbed them with one finger, feeling her wetness. She moaned in my ear. I flicked my finger gently over her clit, which caused her to shudder and grab my hard cock. I moaned and rubbed her harder as she began to stroke me. Her small hand felt amazing as it slid up and down my hard shaft, and I loved the way her cunt felt. She clamped her legs down tight around my hand and bit her lip as she came, silently except for an almost inaudible whimper.
