An Unexpected Summer

Time by the grill with her dad, I thought, would be a welcome reprieve.

He wasn't talkative at the best of times, and it was clear that setting up the grill was something of a sacred process for him. Ten blessedly silent minutes went by during which the only words were "more charcoal."

It gave me plenty of time to think about what the fuck had been happening.

Summer was clearly an incontrovertible tease. I didn't know if it was just because I was her sister's boyfriend, if she was sowing her wild oats, or what. But it was obvious she wasn't going to let up.

And, I admitted to myself with a flush of shame, I couldn't handle it. She...she was just so

hot

. I struggled to form a complete sentence with her, let alone to keep from blowing my load.

Which brought up another point: I had a sinking sensation that if she made me cum, it was going to be

bad

. I suspected my relationship with Jessica would effectively be over. What was I going to do, marry Jessica and start a life with her, knowing I'd see Summer in a bikini on every family vacation, raising an eyebrow suggestively at me and asking whether she had any nieces or nephews on the way? Cornering me by their pool to ask her to rub sunscreen in her back again?

Hell, the rest of

this

vacation would be an endless series of thinly veiled innuendo and teasing that my relationship with Jessica might not survive.

And Summer might not let up even if she did get me to cum, anyway.

I took a shaky breath at the surge of arousal, anxiety, and guilt that flushed through me at that thought.

What should I do?

Well, I

shouldn't

cum for Summer. I loved my girlfriend. I was already wracked with guilt; that would fuck things up beyond repair, whether she knew or not.

That meant two things: I needed to avoid being alone with Summer, and I needed to find some alone time and rub one out. Maybe more than one. There was no fucking way I lasted through

weeks

of her teasing without relieving myself. If it got much worse I'd be blowing my load in my pants when she walked into a room.

I needed

relief

. I'd be less horny, more able to ignore her and manage the situation. Get my head on straight.

As I had this thought, her dad and I both turned at the sharp

hiss-snap

sound of the metal top being popped off of a glass bottle of beer behind us.

"Grill just about set up? Jessica sent me to check before she and Mom start bringing the food out."

Summer

. Of course. She sipped innocently on the beer, one eyebrow raised.

"Grill's set up, yeah, but it'll be a few more minutes and some adjusting before the heat's right," her dad gruffed out.

I was barely listening. Summer was still wearing the bikini top, although she had pulled some shorts on over the bottoms. As I watched, she pressed the cold bottle of beer to her upper chest by her neck -- as if enjoying how cool it felt.

But all I saw was the way a bead of condensation slid off the bottle, and down between her tits. Where my cock had been, not that long ago.

She continued speaking. "Well, I know it's hard work. At least the weather's nice. A little hot out, though." She continued to touch the cold beer to her neck.

Her dad grunted an agreement. "You could help if you want. Give Jason here a break."

She giggled and shook her head. "Oh, no. Hard work like this is a

man's

job."

Her dad sighed and turned away from her, back towards the grill, busying himself with some adjustments. "Well, Summer, you've gotta find something that's hard to do that you like doing anyway. That's what

work

is. Everyone has to do it eventually, like it or not. Your sister understands that. You will too, one day."

I blinked. It was the most I had ever heard him say. His tone was weary; obviously, this was a conversation they'd had many times before. Probably the subject of the argument they'd had earlier today.

"I know, daddy..." she said the words softly. But she wasn't looking at him anymore. As she spoke, she made eye contact with me. She slid the beer bottle lower, down between her tits, and ran the bottom edge along first one full breast, and then the other.

"I guess I feel like there are some things that

come easy

for Jessica that are

hard work

for me. And, y'know...."

As she spoke, she slid the bottle of beer lower, so that it was nestled between her tits. Staring at me, she took one arm, scooping under her tits, and pushing them together. Wrapping them around the bottle.

Exactly the way that she had wrapped them around my cock. I was staring, openmouthed. I couldn't help it.

Summer continued, staring at me. "Well, vice versa, or whatever. There are some things that are hard work for Jessica. But I just know they'll come

so

easy for me."

She broke eye contact with me, and looked down at the bottle of beer, nestled between her big tits, only the neck of the bottle visible. As I watched, her tongue flicked out, stroked across the opening of the bottle. She looked back up at me, and mouthed, again,

come so easy.

Then she blew me a kiss.

Fuck. I was rock hard. She watched with a sly smile as I adjusted my length in my shorts to make it at least

slightly

less visible.

Her dad -- who, I have to admit, I had forgotten was there -- was still absentmindedly poking at the grill, back to us, oblivious. "Okay, I think we're about ready."

I opened my mouth to speak, but, Summer, grinning at me, beat me to it. "Oh, great. Jason, do you mind running inside and letting Jessica know we're

getting close

out here? So they can start bringing the food out?"

Face burning, I grunted an acknowledgement and practically ran for the door.

---

An idea formed in my mind as I headed back inside.

"Hey, you two -- the grill's about ready if you want to take food out." I turned to Jessica. "Um, babe, could I talk to you for a sec privately? It's nothing serious, but maybe your mom can get started. We can help bring the rest out in a minute."

Jessica looked at me curiously. "Sure thing."

I led her downstairs to our bedroom, and shut the door behind her.

Jessica was clearly perplexed. "Babe, wh--" I cut her off with my best long, slow kiss; the kind I knew she loved. I stroked her back with one hand, and reached down with the other to cup her pert ass.

When I broke the kiss fifteen or twenty seconds later, she was breathless, excited. "

Mmm

...what was that for?"

"I just feel like I haven't gotten to hang out with my girlfriend as much as I wanted to, so I thought while your mom, dad, and sister are occupied

outside

, getting food ready, maybe you and I could occupy ourselves in here." As I spoke, I put a hand on her shoulder and guided her down onto the bed, and then stood in front of her.

She looked aroused, but uncertain. "Are...do you think we have enough tim..." she trailed off as I dropped my pants, and revealing a thick, heavy, throbbing erection.

She stared. "

Oh

. You...wow...you're...really...excited already..." She had always liked the way my cock looked. I moved to stand between her legs.

"Well, it's been a while...like I was saying the last night, I want you, and I think if we're quick..." I tried not to blush, thinking about what Summer would say about me being quick. But I knew that I

would

be quick. I'd be lucky to make it inside Jessica at this point. I needed this so badly.

"

Mmm

." She was biting her lip, the way she sometimes did, looking at my cock with a combination of nervous concern and excitement. I had always found that look on her hot, and this time was no exception. She didn't resist as I gently pushed her back onto the bed.

"I know we need to be fast, but you have to go slow with that big thing, Jason," she murmured, staring at it as I pulled her shorts and panties off.

"I will," I agreed, readily, eager. If she had told me I needed to wear a funny hat or do a dance, I would have agreed to that too. The prospect of climaxing -- with my girlfriend, guilt free, no weird teasing from Summer -- was intoxicating. I was

finally

going to take the edge off.

Slowly, gently, I worked the thick tip of my cock up and down her vagina. She was wet, but I knew it was going to be tight. Fortunately, I was dripping precum. She let out a little gasp. "

Ah

-- what has you so worked up,

mmm

?"

I couldn't tell her the truth, obviously. So I lied. I tried not to blush, kept my eyes focused on gently rubbing the head of my cock up and down her vagina, toying with her folds, now. "You, um, looked so fucking good in your swimsuit earlier...I, uh, had a really good dream while I was napping..."

She let out a little whimper as I started to slip into her. "

Mmmph

...what did you dream about?"

Shit. I wasn't prepared with details, and I was so turned on I could barely think. So instead of coming up with some useful, original lie, I twisted the first thing that came to mind. "I, uh...in the dream you gave me a handjob...under the blanket, while we were watching the movie..." I was playing with fire, I knew, but I was turned on, and it was easier than making up something completely new.

She half-gasped, half-giggled in surprise. "

Oh my god

, can you imagine if we did that? Right next to

Summer

?" She slapped my arm playfully, and then fingers dug into my shoulder and her giggle turned into a moan as I slid more of my thick length into her and leaned on top of her. "

God

, Jason...

slow

...you're so big..."

I grunted in acknowledgement. I was struggling to manage my own arousal. I didn't want to blow my load just because she mentioned Summer -- I knew that would be weird. But the truth was, the only things stopping me were that I was really trying to be gentle with Jessica, and the massive spike of guilt I felt when she said Summer's name.

"She really has a crush on you I think," Jessica murmured, looking down our torsos, at my thick cock, half-buried in her. "After you left, she kept talking about how she wanted to make sure you were satisfying me..."

I grunted again, trying to work my cock in deeper. "What'd you say?"

"I told her the truth," Jessica moaned the words out. "That I can barely handle your big dick..."

Fuck. I loved it when she talked like that. I pulled my length out an inch or two, then worked it back in again, lubricating more of my thick cock. It had only been a few seconds, but I could feel myself breathing hard. I knew I was getting closer and closer to cumming. "How'd she...y'know, respond?" I had overhead it, but I wanted to hear Jessica say it.

"She...thought it was hot..." Jessica, moaning, closed her eyes as I pushed in deeper.

Fuck

. I felt my orgasm surging closer at those words.

"W...what do you mean?" I was barely holding on, but was trying to last, trying to get her to talk more about how Summer had reacted.

The reality of that sunk in. I wanted to blow my load

hearing my girlfriend tell me how badly Summer wanted me

. I felt guilty about it, but I was too turned on to care.

"S-she said that if there was ever cloning, she had first dibs...I--I think she wants to

fuck

you..." she let out another whimper.

This

was what I wanted to hear. I started thrusting into her more steadily -- trying to be gentle, but my restraint was rapidly disappearing.

"

God

, babe..." she was staring down at my thick cock again, gaze fixated on it as I thrust into her. "I-I

can't

...take this...for long...taking this big dick...is hard work...

fuck

..."

"You're doing great..." I mumbled. I wasn't thinking about her. I was imagining Summer underneath me, saying the same thing, submissive like Jessica was being, barely able to handle my big dick...

And, thinking of that..."What else did she say? Anything?" I grunted the words out. I felt guilty, asking my girlfriend to talk about this. But she seemed to be enjoying it too, and I was building towards a colossal orgasm, imagining Summer, desperate for my thick cock, struggling to take it like Jessica...

She moaned, trying to keep talking. "H-her face lit up when I said I could barely handle it...to...to be honest...I think it turned her on, knowing I'm getting

fucked

by my boyfriend's big, thick, co--"

I could feel myself about to crest over the edge...but she cut off, freezing abruptly, as we both heard Summer's voice, calling, from the kitchen. "Hey, Jess? Jason?"

Summer.

I cursed her sense of timing.

Making a sad, sympathetic, expression, Jessica mouthed

shit

, and pushed at my hips. Reluctantly, I pulled back, out of her.

Stopped before I could cum.

Again

.

"Up in a minute!" she called. She rapidly dressed.

I was watching her put her clothes back on, glumly. "I'm, uh...gonna wait for this to..." I gestured at my erection, frustrated.

She giggled, and nodded. "Ok. See you in a minute." She paused, and in a whisper, added, "Sorry you didn't get to finish...maybe later..."

As I sat there, trying to think unsexy thoughts, grinding my teeth in sexual frustration, I heard Jessica say something to Summer -- slightly muffled, but audible, making some excuse for why I'd be another minute or two.

Then I heard the screen door open and close, the two of them heading out to the deck. And then screen door open again, her mom coming back inside.

Never a moment alone.

These fucking thin walls.

And then, with a sinking sensation in the pit of my stomach, it dawned on me: I

hadn't

heard the screen door open and close before Summer had called down to us.

She must have snuck back in quietly. I wondered how long Summer had been in the kitchen for.

I wondered how much she had overheard. I wondered if she had heard how her sister could barely handle me.

I resisted the thought that came next. I felt guilty, ashamed it even crossed my mind. But I couldn't help it.

I wondered if she had liked it.

---

I spent the rest of the day in a haze of arousal and guilt. I tried to stick with Jessica to the point where it was probably weird for her family.

But it didn't matter. I knew I couldn't afford to risk being alone with Summer. My plan to try to sneak away and get off with Jessica had backfired; I was only

more

aroused,

less

able to resist her.

While we all ate burgers on the deck, I kept surreptitiously looking at her tits. She was still wearing her bikini. There was no harm in

looking

, I told myself. But I couldn't stop thinking about how they'd felt around my cock, the knowing look on her face, how helpless I'd been, how quickly I'd been brought to the edge...

I waited for her to give me some kind of significant look, to crack a joke, to reference one of the lines Jessica had said while she was fucking me. Maybe just to squeeze one of her tits and blow me a kiss in a moment when I was staring at her and no one else was looking.

But instead, Summer was more or less treating me normally, as far as I could tell. No sidelong glances, no teasing innuendo. A few jokes at my expense -- but there were plenty of teasing remarks about her dad, mom, and Jessica too.

It left me feeling off-balance. I was just waiting for the other shoe to drop, clinging to Jessica's side, terrified that Summer would find me alone. I knew it would only take a single moment of weakness to have me wrapped around her finger again.

So burgers on the deck turned into cards in the living room with Jessica. Turned into snacks instead of dinner. Turned into chatting with Jessica and her dad about firewood. Turned into chatting with Summer and Jessica about college classes.

And that turned in to bedtime.

I was, admittedly, confused as hell. Summer had just...left me

alone

all afternoon and evening. I didn't know what to make of that. I was anxious, aroused, guilty...maybe disappointed?

But in the end, I was also exhausted. The constant anxiety, worrying that Summer would do or say something, had me worn out. So I was happy to drift off to sleep next to Jessica.

I had

wild

dreams, as a result. Summer, fucking me in the bed, a smirk on her face as she rode me, with Jessica asleep next to me. Summer, giving me a blowjob, Jessica watching her sister deepthroat me, shocked. Summer giving me a handjob again under a blanket while we watched a movie -- but this time I couldn't get up, couldn't stop her, she was going to make me cum right next to Jessica...

---

I started awake, guilty and aroused. Fortunately -- or maybe unfortunately -- they weren't

wet

dreams. So when I woke up I was fully erect.

I glanced over at Jessica -- still asleep. It was early. The house was quiet.

Groggily, I decided that enough was enough. The morning wood was urgent, almost painful.

Fuck it

. I had to get off.

I rolled out of bed, went into the small bathroom, and turned the shower on. Once the water had heated up, I stripped down and got in.

The stall was narrow -- one of those shower inserts that's only half the size of a normal tub, and barely wide enough for me to keep from having to hunch my shoulders inward.

I didn't care, though. I was still hard, and I started jacking off. This wasn't going to take long. I felt ashamed about how out of control I was, how quickly I could feel the orgasm overtaking me, how my thoughts focused on Summer instead of my girlfriend, but I told myself that this would help.

And it was just too hot to think about Summer, here with me in the shower, taking my big dick.

I started, guiltily, as the door to the bathroom opened. Mentally cursing, I stopped stroking. I should've locked it. I tried to play it cool -- which meant stammering, "Oh, h-hey babe, didn't expect you to wake up..."

There was a giggle, and then Summer's teasing voice, quiet, but clear. "

Babe?

I don't know if I'm ready for that kind of nickname, Jason. You're moving kind of

quick

...but I guess that shouldn't surprise me after how

quick

you've been so far...

"

Shit

. There were

two

doors into the bathroom -- one to our bedroom, one to Summer's. And I trailed off, speechless, as Summer pulled back the shower curtain and stepped into the shower with me.

She was naked, and her body was against mine immediately under the hot water -- she didn't have a choice, there wasn't enough space for anything else. I stared down at her as she pressed her big tits against my stomach. I could feel my cock against her abdomen.

"W-what are you doing? G-get out..." I was completely off balance.

She looked up at me with a sly smile. "Is that what you really want?" She reached down with one hand, running it along my wet length. "Or do you want some

help

?"

I groaned at her touch, but I had more resistance than I had expected. "We can't," I hissed. I pushed her hand away. I was kind of impressed with myself.

She ignored me. "We can't

what

? I heard you and Jessica yesterday, you know."

I had nothing to say to that.

"You were thinking about me while you were fucking her." She brushed her hair -- wet now, in the steamy water -- out of her face. The movement shifted her tits -- full, round -- against me, hard nipples grazing across my skin.

I couldn't deny that, so I just moved on. "You can't be here, Jessica could--"

She cut me off, giggling. "I can't believe you told her that you dreamed about her giving you a handjob under the blanket. That's

twisted,

Jason. Even I think so."

I flushed and fought with my own arousal -- tried to ignore the feeling of her tits on my abdomen, my cock brushing against her stomach. "I-I didn't...you...we were just talking. It was a hot fantasy. That's all."
