An Unexpected Summer

As I stepped back into our room, I was a guilty, nervous wreck.

I felt for sure that Jessica would somehow

know

that I had fucked her sister in the shower.

But it became clear that she had no clue. I watched her pull a pair of leggings and a t-shirt on as we chatted idly in our room, and then went upstairs to make coffee.

Somehow, her not knowing made it so much worse. She held my hand when we went for a walk through the woods with our morning coffee, leaning in to kiss me as we found a log to sit on, out of view and away from the family cabin.

The quiet of the woods was serene. I returned the kiss halfheartedly, trying to gather my thoughts.

Unfortunately, all Jessica seemed to want to talk about was Summer.

"That dream I had was really hot," she said, her eyes sparkling. "We

have

to find time for you to fuck me later. Maybe Summer and my parents will go to the store or something."

"Mmm," I agreed. I tried to make it enthusiastic. I was worried it sounded noncommittal.

Jessica didn't get really, truly

horny

-- or at least, didn't show it -- all that often. She was mostly responsive to my mood. And I didn't mind; I was generally happy to be the initiator.

But this was clearly one of those rare exceptions. She leaned into me, and put one hand on my inner thigh. "I thought it was so fucking sexy, what you said this morning," she whispered into my ear.

"W-what?" I was trying my best not to think too much about what had happened this morning. To be honest, I could barely remember

anything

I had said when I had been in the shower anyway. I could remember the way Summer's tits had looked, glistening, with water beading on them. The way she'd felt as she smoothly slid my thick length into her, how overwhelming it had been, the way her lips had parted when she felt me cumming...I was getting hard, I realized.

Shit

.

"Oh, you know...when you were in the shower, and said you'd make Summer cum in one thrust..." Jessica looked a little embarrassed to be talking about it, but I could see that she was flushed, turned on.

"I...I like thinking about how easily you'd handle her," Jessica confessed. "She's been bragging about her sexual exploits a lot since she went to college, and it's just...

hot

...to think about you dominating her, using that big dick the way you do on me, only she doesn't have my practice with it, couldn't handle it..."

She trailed off, biting her lip.

I was blushing. I couldn't help it. I had fantasized about doing that to Summer, too.

But that wasn't what had happened this morning. I couldn't handle Summer. She had gotten me so worked up, so turned on,

I

had been the one to cum in a single thrust. The way she'd moved, how her body had felt...

And that brought me to the other thing I was feeling ashamed about. Summer had said I owed her an orgasm. That she wouldn't stop teasing me until we were even. And, against my better judgment -- I

wanted

to get even. Wanted to show her. But based on how quickly she had gotten me off -- or almost gotten me off -- on this vacation so far, I didn't even know if I could. And the mixture of arousal, guilt, and shame had me totally confused.

As I was thinking about it, Jessica slid her hand up my thigh, and let out a scandalized giggle. "Oh my god,

babe

. You like thinking about it too, huh?" She fondled my thick length through my shorts.

"I, uh, yeah, I guess it's pretty hot..." I muttered the words, torn about playing along with this.

She looked around. "And you haven't gotten to, you know...

finish

...in days, since Summer interrupted us having sex yesterday," she mused, sympathetically. "I felt so bad about that..."

"Uh...right," I lied. I felt like an absolute heel, the way it felt as Summer sank down on my cock playing back in my mind. The way I had sprayed a load into her as soon as she started moving on me.

"We'd hearing anyone coming before they could see us," Jessica said. "We could, y'know..." as she trailed off, tantalizingly, she started unbuttoning my pants.

My arousal and guilt warred with each other. On the one hand: I loved Jessica, she was hot, and she was obviously very turned on. I desperately wanted to put what had been happening with Summer behind me; sex with Jessica would help, I was sure.

On the other hand: I had been fucking her sister

an hour ago

. Doing this now felt wrong. And Summer had made me cum so quickly.

Way faster than Jessica did.

The thought made me feel even worse.

Jessica misinterpreted my hesitancy. "Don't worry, I'll be quiet," she said, softly, staring down as she pulled my thick cock out of my pants and boxers. "We'll hear them before they hear us, too..." as she spoke, she stood up in front of me, pulling her leggings down her slim legs. She stepped forward, straddling me, lining up the blunt head of my cock with her entrance.

"Fuck, I'm so wet for you..."She closed her eyes and moaned, as she felt the tip of my cock brush against her. "And you're so

big

...you have to go slow..."

I was grateful that her eyes were closed, because I definitely winced.

Summer hadn't needed me to go slowly.

I couldn't help the comparison.

But then Jessica whimpered as she sank down on me further, and the physical sensations took over -- her lean body atop mine, the feeling of her thighs against me. I reached up, cupping one of her breasts through her t-shirt, my other hand drifting to the small of her back as she lowered herself.

"G-

god

, you feel good. I needed this," she groaned. I could hear the struggle in her voice, feel her stretching around my girth to accommodate me. She

was

wet, and I reflexively bucked my hips up.

"Ah, fuck, Jason,

easy

, you're so thick..." she lifted herself back up and resumed working me into her slowly.

"Uh, sorry..." I muttered the words, and tried not to make the mental comparisons to her sister. I tried to focus on moving slow for Jessica, and how she felt, wet and tight around me.

Slowly, she sank herself down lower, gasping as she worked my full length inside her. "Fuck, baby, your cock feels amazing," she whispered.

I groaned. So did she. It felt more normal by the second, more like

us

, as she stared into my eyes. Jessica didn't often ride me the way that she was now -- I think she generally preferred me being on top, taking charge -- but I could tell she was enjoying this. And so was I.

She was making a series of small moans and whimpers as she worked herself up and down my length with quick rocking motions. "I love the way you fill me up, Jason," she whispered. And then her voice took on a naughty tone. "God, Summer would've cum already, wouldn't she? Fucking this big dick..." she started working herself on me more vigorously, stroking herself further up and down my length.

Probably not. I would've cum already instead.

I knew my face was red. "I, uh, y-yeah..." I stammered the words out, guiltily. I hoped she'd chalk it up to arousal, but staring into Jessica's eyes, all I could think about was the expression on Summer's face as she had smoothly impaled herself on my thick length.

Fortunately for me, Jessica seemed too turned on to be paying much attention to my reactions. "It's so hot to think about how easily you'd fuck her to an orgasm," she moaned. Her motions were almost frantic on my cock now, the rhythm disappearing as she started to lose control. "This thick cock...it's just...overwhelming...she's smaller than me, she couldn't..."

And then her words dissolved into a cry, and she buried her face in my shoulder as she came, hard, moaning into me. I tried to maintain the rhythm as she shook and quivered atop me, slowing as her orgasm subsided.

Eventually, she looked up at me, a shaky grin on her face. "

God

, that was good..." she murmured the words, slowly starting moving again.

Fuck. I was close to cumming myself. That had been

hot

. Jessica rarely lost control like this, hardly ever talked dirty. She was obviously getting off on thinking about me dominating her sister.

Jessica was clearly having similar thoughts, starting to move faster again, now, a naughty smile on her face. "She wouldn't be able to handle you...but

I

know how to make that big dick cum," she whispered in my ear.

I tried to bury the guilt I felt, and just grunted agreement. I put my hands on my hips and started thrusting up into her. I had been letting her set the pace, but I couldn't do that anymore; my self-control was gone.

She let out a surprised moan. "Yeah, show me what you'd do to make her cum quick," she whispered.

I thrust up into her, hard and fast, for another ten or fifteen seconds, thinking about what it'd be like to make Summer cum, the confident smirk she'd had on her face. I let out a little growl in the back of my throat and started moving faster. Yeah, Summer had made me cum quick, but that was only because I had been teased mercilessly for days. She was small, younger than me. I could show her, put her in her fucking place, just rail her into submission...

Jessica gasped at the sudden ferocity, the change in tempo. "Oh,

babe

, yeah, fuck me...show me what you'd do to her..."

I was thrusting into Jessica with abandon now, thinking about what it'd be like to make Summer cum all over my cock.

I was just about to cum when we heard the crackle and rustle of someone moving towards us through the woods. We both froze.

"Jessica? Jason?" It was Summer's mother, moving towards us from the house.

Fuck

. We frantically separated and moved to redress quickly. I finished awkwardly stuffing my thick erection back into my pants and trying to adjust it to be at least somewhat less prominent. Jessica glanced at me, confirming that I was clothed, before shouting back, "Mom? Was that you?"

"Yeah, honey. Wow, you guys are really back in the brush, huh? Well, c'mon in, Summer made pancakes for everyone and sent me out to get you!"

Sorry

, Jessica mouthed again. She looked sympathetic. That made me feel guilty all over again.

I

was

frustrated...but probably not as frustrated as I could've been. Since, you know, Summer had made me cum only an hour beforehand.

And, I was sure, Summer had also sent her mother out to get us, to make sure Jessica didn't get a chance to finish me as well. She

wanted

me on edge, frustrated.

Fuck

. What was I supposed to do about this?

—

Jessica, to her credit,

really

seemed to want to get me off. She kept trying to find time for the two of us to be alone.

But the rest of the day was a series of endless interruptions. We went out to the pool, and just as Jessica asked if I wanted to help get some sunscreen under her bikini to make sure she didn't get weird tan lines, her Dad showed up. Summer had evidently told him I had asked about how to check the pool's pH and chlorination, which he was all-too-happy to help teach me about. At length.

Jessica and I went to take a nap...but as soon as she had run her hands down my torso to wrap them around my cock, with a whispered giggle in my ear, her mom knocked on the door. Had Jessica perhaps borrowed her conditioner? Summer mentioned she thought it might be in our bathroom. Could she check?

Then, later on, Jessica said the two of us were going to go for a walk. She bit her lip and made eye contact with me as she said it. I agreed, readily...and so did Summer. She thought a walk would be a great idea. So she trailed along behind the two of us, chattering incessantly. No privacy there.

In short, by the end of the day, I was on edge -- both mentally and physically. It felt like my

girlfriend

had basically just been teasing me all day long. But I knew it was Summer's doing, part of her plan. I ground my teeth just thinking about it. It hadn't even been a full day and I was right back to feeling like I really needed to get off. I was, at least, so focused on how turned on I was that there was less brainpower for how guilty I felt.

I had one thought: Jessica and I could just stay up later than everyone else. Jessica liked that idea. Her parents would be easy -- they turned in around 9pm. That just left Summer. All we had to do was wait for her to go to bed. We could hang out on the deck. The idea of a few uninterrupted hours with Jessica - no distractions, no Summer - to reconnect and have some sex seemed like just the antidote. I could put the last few days behind me, I told myself, firmly.

But a few hours later and Summer, for her part, didn't seem like she was going to do that. She had changed into another outfit she claimed were "pajamas". She was wearing a little pair of red cotton boy shorts that barely covered her ass, and a plain white v-neck t-shirt. With how low the v-neck went, and from the way the t-shirt clung to the curve of her breasts, the barely-visible hint of her nipples through the fabric, I could tell she didn't have a bra on. I did my best not to stare.

It was a warm, clear, night, and we all went out onto the deck with our drinks, sitting in chairs around the little patio table they had out there. Surrounded by the woods, with only the dim light from the kitchen behind us, it was dark -- we could barely make out each other's faces.

But it did make for beautiful stargazing, I reflected, as we all looked up. The sky was startlingly clear, and with no light pollution, the Milky Way stretched across the night above us.

"Damn," Jessica said softly. "You know, when we were kids, I don't think I realized how special this view is. You just don't get stars like this most places."

"Mmm," Summer agreed, sighing. "I've always thought views of the stars like this are kind of romantic, aren't they? Reminds you of how big the universe is...and how small we are."

I looked away from the sky at her. Her expression was unreadable in the dim light, but I could see she was making eye contact with me. I thought I detected an amused twist at the corner of her mouth, a slight teasing note in her voice. We hadn't said two words to each other since the shower earlier this morning, but clearly her attitude hadn't changed.

Jessica was still looking up; didn't seem to have noticed any of this. "Yeah," she said, a little dreamily. She yawned, and reached over to take my hand.

"Oh..." Now the amusement in Summer's voice was more pronounced. "Should I leave you two lovebirds alone together? It's a romantic view, and the last time I was out on a night like this with a guy I was seeing, I remember what

we

wanted to do..."

That

was an offer I was ready to take. Some romantic lovemaking with Jessica out under the stars the whole point. I opened my mouth, mulling over how to artfully suggest that, yes, Summer should head in to bed.

But Jessica latched on to Summer's suggestive second thought, not her first. "Oh my god,

Summer

," she said in a scandalized, delighted voice. "When was this? Who was this with?"

My heart sank and I closed my mouth. So much for that.

Summer smiled slyly. "Are you

sure

you and Jason want to hear about it? I'm worried you'll think I'm, y'know, gross, or..." her voice dropped to a whisper. "

Slutty."

That word, coming out of her mouth, sent the blood surging to my cock.

"C'mon, we would never think that. Right, Jason?" Jessica leaned back, settling in against my arm, now, and yawned again, clearly hoping for a story.

I nodded, a little reluctantly. Summer's smirk left me feeling nervous about how this was going to go, but what was I going to say?

"Okay. Well..." Summer leaned forward. I couldn't help looking down at the enticing shadows playing over the valley of her cleavage in the dim light. Fuck, she had big tits. I remembered how they'd felt wrapped around my cock by the pool.

"...this guy and I had been seeing each other for like, I dunno, a month or so. We had hooked up a few times, I guess, but he hadn't ever...um, you know, gotten me off." Summer giggled, coyly, as if she was embarrassed to be talking about it. But she was staring straight into my eyes, one eyebrow raised.

I glanced over at Jessica. She was still leaning against me, not looking at Summer, staring up happily into the sky, but she let out a little laugh. She sounded both tipsy and tired. "Oh my god. Why'd you keep hooking up with him if he wasn't getting you off at least some of the time? That's like, the whole point, right?"

Summer shrugged, biting her lip. "Oh, you know. He was fun to play with, even though he hadn't gotten me off yet. Tall, cute. And he was, uh, big, you know? I thought maybe there was still a chance. The equipment was right."

"Mmm." Jessica squeezed my hand. "You like them big, huh..."

Summer nodded, and - glancing at me - said, "I mean, don't you, Jess?"

Jessica sighed languidly, still looking up at the sky; I could tell she was recalling the sex we had this morning. "I mean,

yeah

. It's more work, but it's worth it..."

Summer just smirked at that and continued. "Anyway, we had done stuff together, but we either got interrupted by my roommates, or he, well...finished kind of quick. Like that guy in the movie the other night, y'know? But I was hoping with a little romance and taking things more slowly, maybe he'd be able to get me there..."

Was this a real story? Or just some pretext for Summer to tease me? She could've easily been describing the encounters we had been having.

I could feel myself flushing.

"So when he asked me if I wanted to hang out on Friday, I told him sure. We went to a field by our university -- lots of students use the space for drinking or hanging out, but its big enough that you can have some privacy, you know? And away from buildings so you've got a great view of the stars. I brought a blanket and a few bottles of wine. And I wore a sundress I knew he'd like -- red, cut kind of low in front..."

Jessica let out a drowsy little laugh at that. "I mean, you've got the body for something cut low in front, that's for sure." I could hear a little envy in her voice.

Summer glanced down at her own breasts, and then continued. "Yeah, he thought so too. He couldn't take his eyes off my tits."

Neither could I. One of Summer's hands lazily drift up to her cleavage, fingers running along the curve of one breast, down into the valley between them for a moment. I couldn't look away from it. I looked up and realized she was watching me, her eyes just barely visible in the shadows. I saw her lips curve into a smile.

I was hard now, I realized. I couldn't help it. I wished I had gotten off with Jessica this morning. I tried to shift myself to avoid poking Jessica with my cock. Jessica pulled her eyes off the sky to look over at me instead, irritated with how much I was moving. But at least she didn't look down at my increasingly hard cock.

"S-sorry, the mosquitos are biting," I mumbled.

Fuck.

How was I in this situation

again

?

Jessica settled herself against me once more, let out a contented sigh as she stared back up at the stars, and then, sleepily, said, "So what happened?"

Eyes on me, Summer said, "Well, I was determined not to make him, y'know, um...cum too fast." She giggled as if titillated by her own vulgar language. "So I took things slow...long kisses, lots of looking into each other's eyes...every time he started to, y'know, signal he wanted to do more, I stopped him." I was fully erect, my cock uncomfortably confined in my pants.

Summer was staring right at me, voice low, almost hypnotic, now. "I could tell he was really excited. Like I said, he was big. Hard for him to hide it, y'know? And I do mean

hard

." Her chuckle this time was lower, seductive.
