As late-summer days go, this one was shaping up to fall in the 'glorious' column. The weather was fantastic. It was the kind of sunny and warm day that made you want to get out and do something fun. And, it was the kind of warm, sunny day that compelled people to wear very little clothing. Like most of the beautiful young women on campus for the summer, Penny did not disappoint.
She wore a summery, short blue skirt that came to rest just at the mid-point of her tan, toned thigh. In combination with the tight white spaghetti-strap tank top that she wore with no bra, it set off her features in such a way that she was turning the heads of both men and women alike as we strolled down the main street of the lazy college town.
Penny's perpetually semi-hard nipples pressed outwardly from her perky b-cup tits, a fact that more accentuated her strength and womanhood, than made her seem lewd or cheap. As always, she carried her toned 120 pounds on her 5' 8" frame with perfect posture and shoulders back. Her auburn hair was pulled back into a neat ponytail, and looked soft and silky as it shone in the sunlight. Ray-ban Aviator sunglasses hid her gorgeous green eyes, giving her an aura of complete confidence.
Me? I suppose you could summarize it by pointing out that I'm no fashion mogul. The simple read tank top I wore read 'UNIVERSITY' in white block letters, and it may, or may not have matched what I like to refer to as my 'utility' khaki shorts that came down almost to my knees. I prefer the term 'utility' to 'old' or 'crappy' for reasons of aristocracy. My ensemble was replete with flip-flops: the obvious footwear of choice for such a well thought out wardrobe. In truth, my look could have been better if I had blond hair and I was carrying a surf board, but my beach-comber style was more coincidental than well-executed.
Occasionally, we'd meet a friend of hers on the street and she'd introduce me as Tim, which was unsettling when she first did that at the party last night, but I was starting to get used to it. Most importantly, she genuinely seemed to be as proud to be with me, as I was with her. Of course, we were both neglecting to mention that we were brother and sister, instead opting to let people draw their own conclusions. Mind you, It wasn't by design. I like to think it was more a byproduct of both of us wanting to spend time together as more than just brother and sister, without freaking anyone out and then having to deal with the resulting social stigma that would undoubtedly cloud her remaining college career. Incest, as it turns out, may be a popular topic on literary porn sites, but in the real world, uh, not so much.
That notwithstanding, Penny and I spent the day together very much as boyfriend and girlfriend. We did a little walking around, a little talking, a little shopping, a LOT of flirting with each other, and we even had a little lunch. Neither of us missed an opportunity to touch, or discretely grope the other. It was fun, and it felt so natural.
Along the way, I realized (though not cognitively at the time) that it was much more than Penny's panties that made my dick hard, though they certainly, nearly constantly, did. What made Penny more attractive to me than any other girl I'd met to that point in my life was that she stimulated me both physically and mentally. I suppose as I look back on it now, on one hand, the fact that Penny was my sister could be considered a cruel twist of fate; but on the other, it served to teach me to pursue similar women, women who were not only beautiful but also intelligent, as potential love interests but I digress.
"My pussy gets damp every time I think about you fucking me this morning," she whispered as she leaned into me while we waited for our food at lunch.
My dick twitched and began that familiar swelling as I leaned back and said, "I'd love to sit you on this table, and lick you until you came, while all of these people watched."
"You naughty little pervert. You'd like that, wouldn't you," she said with a sly grin and a sparkle in her eye as her hand eased across my lap, giving my dick a playful pat.
"You know I would, and I think you probably would too. I'd kill for the chance to make you cum in Brittany's panties right here, right now," I said, and I meant it.
I let my hand come to rest on her smooth, supple thigh just where the hem of her skirt rested. Even though the café-style restaurant was mostly empty this mid-afternoon, we had chosen to sit side-by-side in a corner booth. The notion of licking Penny's pussy in an erotic public display was a wickedly delicious idea, regardless of the sparseness of the audience. As my mind quickly toyed with the logistics and potential consequences of somehow getting her on the table in preparation for a thorough tongue-lashing, my fingers began gently caressing her soft skin, easing her skirt higher on her thigh.
We noticed our waitress approaching with our food, but neither of us made any move to withdraw our hands. As she arranged our plates in front of us, her playful smile made it clear that our light petting had not gone un-noticed. "You two take all the time you need, if you need anything, I'll be up at the bar," she said as she prepared to leave.
"Thanks, good to know," I replied with a smile. With a slower than normal turn, our waitress was gone, and we were left to our relative privacy.
We seemed to take turns between nibbling on our lunches, and advancing our little game of foreplay. I'd run my tongue along the split in the edge of my sandwich before taking a bite, and then return my hand to caressing her thigh, ever testing the boundaries by inching her skirt higher and higher. She would perform mock fellatio on a French fry, or lick the shaft of the straw in her diet Coke, and return her hand to rub or squeeze my hard dick. We smiled and giggled the whole time, but I could see her cheeks becoming flushed, and my cock was beginning to ache for release.
My hand had found its way to the soft, sensitive flesh of her inner thigh, all the while easing toward her warm cleft, and soon I could feel the silky softness of the crotch of Brittany's panties on the back-side of my hand. In an attempt to prolong the teasing, I let my hand rest just against the sexy panties, and continued to knead the soft skin of her inner thigh. Penny's pussy radiated warmth, and it was all I could do to restrain myself from simply ravaging her sexy body.
Outwardly, we were both struggling to act as though nothing out of the ordinary was going on, but we were both horny as hell, and I'd resolved myself to making my sister cum right where she sat in that restaurant, and frankly, I didn't care who might notice. From time-to-time, our waitress would glance over and smile, but she kept busy behind the bar, and left us to our own devices.
"Oh god, you're making me so wet," she said with a sigh.
"That's the general idea. I can't help it. You just turn me on so much I can't keep my hands off of you."
Penny let her thighs gently part, giving me free access to anywhere my hand should chose to roam. I pressed the back-side of my hand more firmly against the soft material that cupped her puffy pussy lips, and gently began a slow up and down rhythm. There was an unmistakable heat that radiated, and a dampness that sent a thrill through my body.
A short gasp of breath escaped Penny's lips and it was apparent that, unlike her pussy, her mouth had gone dry as she worked her tongue over her lips in an effort to re-moisturize. She'd completely let go of my cock, and she was alternating between leaning forward with her elbows on the table, and more reclined using her hands to steady herself. But she'd begun gyrating her hips to maximize the friction the back-side of my hand was providing her clit through the panties.
We made a feeble attempt to maintain some small-talk, but that quickly petered-out as Penny became more-and-more aroused. Penny was trying in vain to disguise the fact that I was firmly pressing my and into her soaking wet slit, and she was bucking somewhat aggressively against it.
I rotated my palm so that my fingers now cupped her panty-covered mound. My index finger parted her puffy lips, and I began pressing Brittany's now very damp panties into her soft folds while maintaining firm pressure against her clit with the base of my finger. Penny's skirt was now bunched high enough above where my hand was diddling her pussy that the soft yellow material of Brittany's skimpy little panties was clearly visible. My index and third finger pressed the valley between her pussy lips and her legs, and I could feel the fancy lace fabric as it eased back and forth across her skin.
"Are you gonna cum for your little brother right here, with all of these people around?" I teased.
"What do you think?" she managed to say between small gasps of breath.
"I think I really want you to. I think I want you to cream all over Brittany's panties. I think I want you to soak them with your pussy juice. Certainly, I would much rather be eating your sexy little cunt right now, but since I can't, I think I want you to cum on my hand while I finger-fuck your pretty pussy in this restaurant. Can you do that for me?"
"Mmmhm" she managed to grunt and I increased my assault on her crotch, making each stroke along her slit longer and deeper.
Our eyes were locked on each other, and penny had a look of desperate wanting. She was struggling to keep quiet, and for a moment I feared it was fighting a losing battle.
"My pussy is on fire," she hissed, followed by a breathless, "I'm gonna cum."
Suddenly, her eyes shut hard and she bit her lip to stifle a moan while simultaneously her hand grabbed my forearm while her other hand gripped the table. Her hips gave one final buck and held still as I could feel her legs quiver, and her pussy spasm. A flood of warm liquid soaked the already wet crotch of Brittany's damp panties, and I nearly came in my pants.
We held very still for nearly a minute while her orgasm overtook her body, and eventually began to subside. When it finally did, her grip on my arm loosened, and her legs fell limp. She took in a deep breath of air, and her eyes softly opened.
"Oh my god," she gasped trying to resume a normal breathing pattern. "Oh my god, that was so incredible."
I continued to gently caressing the soaked fabric and said, "No, you're incredible."
We looked over to see our waitress approaching, and again, I made no attempt to withdraw my hand. Penny closed her legs slightly, but I continued to make lazy circles over her pussy with my finger.
"You two look like you're all finished over here, can I take these plates for you?" she said smiling with a wink.
I replied, "Sure, that'd be great"
Her name badge read "Mo", and as she leaned over to gather our plates, she hesitated for a moment, getting a clear view of my hand between Penny's legs, and the yellow panties beneath her skirt.
As she stood, Mo was blushing slightly as she said to Penny with a devilish smile, "Yellow is a great color on you," and after a momentary pause, she followed with, "Can I get the two of you anything for dessert?"
"Why thank you," Penny responded with an unexpectedly demure smile. Not to be out done, she came right back with, "We'll just take the dessert menu for right now. I think I'm in the mood for something with some cream in it." I nearly burst out laughing, but could only cover my face with my free-hand in mock embarrassment.
"Very good then, I'll be right back with a few menus," was Mo's response as she turned and left with a gleam in her eye, and a wide grin.
As she walked away Penny and I both took a moment to admire her shapely ass in her short white shorts. Very nice, I thought.
Penny turned slightly towards me, smiled and said, "Now what about you?"
My hard cock ached, and I could feel the wet spot in my underwear where the tip had been leaking pre-cum, but truthfully, I had been so focused on the notion of getting my sister to cum that I'd kind of blocked-out my own burning desires. Now, however, mission accomplished, these urges were back to front-of-mind awareness.
With a glimmer, I responded, "What do you have in mind?"
"Well, as tempting as it would be to have you just pull your cock out for me so I could give you a hand job, or maybe even suck that big dick of yours so I can have cream for dessert."
My eyes were wide, and I was nodding, as either of these seemed like fantastic options to me.
Abruptly, Penny's eyes widened, and she said eagerly, "Ohhh, I've got a better idea!"
Of course, this was when Mo returned with the dessert menus, as promised. I still made no attempt to remove my hand from Penny's soaked crotch. Boldly, Mo slid into our booth across the table as she set the menus in front of us. Mo was very attractive in a 'cute' sort of way. A young woman I'd guess to be 19 or 20 years old, she was curvy, but certainly not overweight. Her hair was black and she wore it in a bob that framed her face nicely. She laid her forearms and hands flat along the edge of the table, and when she leaned forward, her full tits were elevated as they pressed against her wrists. Her nipples were hard and clearly visible, begging for release from under her pink polo shirt.
In an attempt to act casual, but still grinning from ear-to-ear, she said, "allow me to recommend either the cherry cheese cake, its verrrrry creamy, or possibly a piece of the devils-food cake, that has a wonderful cream filling. If you're in the mood for a piece of pie, I can arrange that, too, if you're at all interested." Her innuendo was none to subtle.
"Hmmm, to tell you the truth, I'm not too sure what I'm hungry for. it all sounds so good," Penny toyed as she browsed the menu.
My eyes scanned from erect nipple to erect nipple, and then found her name tag above her left breast. "Mo," I said. "That's an interesting name."
"Yeah, it's short for Maria. Mo is just my nickname. And you are.?"
"Oh I'm, uh, Tim, and this is, uh, Penny," I said, as I struggled to not put the preface of 'my sister' to Penny's name.
We all exchanged smiles as Penny chimed in, "Nice to meet you." Looking me dead in the eye, she added, "I think I'd like a plain brownie."
This took both Maria and me somewhat off guard, but after a moment, Maria collected herself and rose from the table saying, "no problem, one brownie, coming right up."
Penny added, "Could you put that in a bowl?"
"Sure," came Mo's response, "I'll be right back."
Penny withdrew my hand from her crotch, and licked her lips.
I was confused. Had I done something to upset Penny?
"Don't worry little brother, I think we're both really gonna enjoy this. Pull that big hard cock out for me."
In a weak attempt to maintain some minimal level of secrecy, I scanned our immediate area, while licking some of the residue of her sweet pussy from my fingers. Then, convinced we were still flying under the radar, I casually reached down, and unbuttoned my shorts. As I was lowering my fly, Penny quickly lifted her skirt, lifted her hips and pulled down Brittany's sexy yellow panties. In a flash, she held them in her hand just below table level, and she was smoothing her skirt back over her lap.
"Holy crap," I thought as I pulled down the elastic of my boxers, giving my aching cock some much needed air. As it sprang free, I scooted closer to the table for privacy, but also turned slightly so that Penny could plainly see my throbbing dick. The head was big, and reddish-purple, and it glistened with pre-cum.
"This won't take long," I said both pleading, and warning, at the same time.
Penny handed me Brittany's panties, and said, "Here, these might help too. But, don't cum until I tell you to."
I held the soaked panties to my nose and began to inhale as I saw Mo approaching with a bowl in her hand. The aroma was intoxicating, but I cut my breath short, and quickly I lowered the panties to my raging hard-on. In a moment of bashfulness, I attempted to lean forward to conceal my boner, and yet look casual at the same time.
Mo set the white bowl in front of Penny with two accompanying spoons for either of us.
"Would you like to join us for a few minutes?" were exactly NOT what I expected to hear next, but sure enough, that was exactly what came out of Penny's mouth next.
"Yeah, sure, it's dead in here until closer to dinner time." And with that, Mo returned to her seat across from us, again propping her boobs up on her wrists as though displaying them on the table for our benefit. "You two look like you're having a great day."
"You wouldn't believe me if I told you," replied Penny coyly.
Mo grinned, "Why, what have you two been up to today?" Penny had her hooked.
"Well, let's see, we started the day with a bang (clearly assuming this obvious metaphor would blow right over her head), and since then we've been out, enjoying the weather, kinda checkin' out High Street, you know, hangin' out. We came in here, had a great lunch, and Tim gave me a great orgasm just a few minutes ago," she casually said with a smile while turning from Mo toward me. "It's been a heck of a day, and it's not even half-over."
I almost burst out laughing at Penny's unabashed candor, but mostly I was speechless. My cock was still aching, and the panties felt exquisite against my turgid pole. There was no telling how long I could hold this pose without spontaneously exploding.
With a hushed giggle Mo replied, "Holy shit, are you kidding? That's so fucking hot!"
"Nope, I swear. He fingered me through my panties until I came… just a few minutes ago." As proof, Penny ran her middle finger between her pussy lips, and held the glistening digit just over the table as proof to Mo.
"Oh my god, that's so fucking hot. I knew you two were copping a feel, but I had no idea."
Penny popped her finger in her mouth like a tiny cock, and sucked it clean, "Mmmmm, delicious!"
Mo giggled again, and blushed nervously as she wiggled slightly in her seat. "Are you two into sex in public places and stuff?"
"Well, I don't think we were before today, but now. who knows?" she smiled with a wicked grin. "Whaddya you think, there, Timmy?"
"'Never say never,' that's my motto," I said with a laugh," the whole time trying to control my breathing so as to not blow my load. I could actually feel the corner of my eye twitch involuntarily as a result of the pressure boiling in my balls, and the mind-blowing way my sister was launching full-on into seducing this girl. My nipples throbbed, and I feared that even one more, slight stimulus and all semblance of control would be lost.
"Wow, that is sooo cool," Mo continued, still not fully grasping the situation, though seemingly eager enough to find out, "I get a thrill out of flashing my tit at a guy, while acting like I don't know what's going on, and I've given 'road head' to a couple of my boyfriends."
Penny leaned toward Mo and partially whispered, "What would you say if I told you that Tim had his hard cock in his hand right now, underneath the table, stroking it slowly with my panties?"
That almost did it. "Baseball, baseball, baseball." I said to myself as I saw Mo's eyes nearly bulge out of her head.
"Those sexy yellow panties you were wearing when he was fingering you? Mmmm. Can, can I see it?" she stuttered.
"Sure, lean up here. Timmy, lean back so we can see, will ya?"
After quickly scanning our surroundings, Mo sat up in her seat, and leaned well over the table as I reclined against the back of our padded booth. My cock head was deep purple, as though I'd literally been 'choking' the chicken and I guess, in a way, I had. The helmet was shiny from the pre-cum that was oozing from the tip. I held the base of my cock with one hand, and pressed my hips forward, extending my rigid pole fully upward. In that position, my six inch cock actually appeared to be more like seven, and the thick shaft was literally bulging with veins. I used a very loose grip to ease Brittany's panties slowly up and down so I didn't lose control. I could have pounded nails with the thing, it was so fucking hard.
"Oh my god. it looks like it hurts," Mo said quietly.
"Tim, you naughty little perv, don't you cum on those panties yet," Penny cooed. "How do they feel on that big fat cock of yours, my panty boy?"
My nipples tingled, and all I could utter dryly was, "Awesome." I looked at Mo's tits, smashed against her forearm, and then at her face, her eyes were locked onto my aching pole.
I shut my eyes, grit my teeth, and tried to remember Pete Rose's batting averages while I gave Penny and Mo a complete display of my cock.
"Oh my, I'll bet that feels really, really good when it's inside you," Mo's eyes were transfixed.
Penny responded, "You have no idea! It hits all of the right spots, and, as an added bonus, the boy has real stamina. Mmmmm, god! It makes me want to climb on him right now, and have him fill my aching pussy"
"Ohhhhh, that'd be so hot, but I don't know." Mo hesitated. "Plus, I don't think he's gonna last too much longer."
I opened my eyes and gave Penny the look that confirmed what Mo had just said.
"Ohhhh, does my little pervy-boy need some release?" Penny said and she licked her lops as she reached for the bowl with the brownie in it. "Here, give me some icing for my dessert."
Without asking any questions, I sat upright, and tried to position my cock so it faced outward, hoping I could control my orgasm enough to comply with her request. Penny held the bowl at an angle just under the table and in front of my cock.
I was breathing deeply, ready to explode, and as I allowed my mind to give in to the fantastic sensations of Brittany's sexy panties against my hot flesh; the fact that a strange girl was nearly laying on the table I'd just had lunch on in an attempt to see me spray my load all over this brownie; the fact that my sister was holding the bowl she wanted my to fill with my cum; well, needless to say, that was more than enough encouragement.
The first jet came hard and fast as I gently stroked my shaft with Brittany's panties, so-much-so, that it partially splashed out and onto my foot. I let out a quick grunt, and then struggled to maintain my breathing so I wouldn't scream out, and totally draw attention to our pornographic little scene. The second, third and fourth streams were intense, but Penny managed to make the adjustment that allowed the bowl, and the brownie, to catch the majority of my load. Hot thick cum drizzled from the head of my now softening cock, and I used Brittany's panties to wipe off what didn't make it on to Penny's dessert.
Penny brought the now creamy dessert above the table to inspect for herself, and then display to Mo, who was wide-eyed, and apparently enthralled by the show.
"Oh wow you guys! That was fucking amazing!" Mo nearly cried as she eased back into her seat.
I had to admit, I was pretty amazed myself. The brownie was literally covered with my white sauce, it appeared to be covered with some sort of sugar glaze, and a fair amount had gathered around the brownie just as the chef intended.
But just then, in typical Penny fashion, she found a way to push the envelope just a little further.
Without hesitation, Penny picked up her spoon, and used it to cut away a piece for herself. My cum stretched in a thin line from the brownie to her spoon as she brought it too her mouth, and parted her lovely lips, and slipped it in her mouth.
"Mmmmmm," she said as she chewed briefly, and then let it slide down her throat. "Yum! Still warm and totally creamy!"
And the surprises continued.
Next she took a spoon full of the erotic dessert, and fed it to me, right before the eyes of our intrigued guest.
Some of my cum dribbled down my chin, but I didn't even consider refusing. Actually, I enjoyed the lewd display for my audience, and I even enjoyed the taste chocolaty and salty to varying degrees. I used Brittany's panties to wipe my chin, and then casually set the sodden panties on the table, like a used napkin.
"Want some?" Penny offered to Mo.
Eagerly she leaned forward, "I was afraid you weren't going to ask," she said as she opened her mouth and held out her tongue.
Penny spooned a healthy portion of brownie that she'd thoroughly coated with my spunk, it was literally dripping when it got to her mouth. A large drop managed to evade her wanting tongue, and it landed squarely on her t-shirt right between her full tits.
"Mmmmm" she moaned as she savored the brownie, and my cum, in her mouth, her pouty lips now slick with my juice. She ran her tongue out and around to ensure she'd gotten all she could.
"Delicious!" She exclaimed after gulping down her prize. As she looked down at the spot on her shirt, she said, "I wonder if anyone will figure out what this is?"
After a few moments Mo bristled, "I'd love the opportunity to get together with you two after I get off work tonight."
Penny and I looked at each other and could immediately tell what the other was thinking, and I made sure to collect Brittany's panties as we exchanged phone numbers.
