With a proper climax or two.

Setting the thoughts of your neighbors in a darkened theater committing acts of **** aside--who are you to judge in that regard, really?--you and Shelly climb into your car, your steady flow of conversation falling into silence for the first time this evening. You sense that both of you are feeling the same thing, a nervous anticipation sitting in the pit of your stomach as you realize that, once you get home, your relationship is going to change once more. You've already taken steps in that direction, from the cute and innocent flirtation of a few days ago to the outright sexual teasing and oral pleasures you've given each other tonight. But having outright sex with your own sister will take things to a whole new level and, even though you both want to fully consummate your love and passion with each other, you have to admit that the prospect is a little scary.

So instead of talking, Shelly leans over and lies her head against your shoulder, snuggling close, just happy to be near you. You take your own arm and wrap it around her, enveloping her in an embrace that calms both your racing hearts and makes you feel more complete than you've felt in a long time.

You break a few speed limits getting home and, after pulling into the driveway, you hop out to open your sister's door. She steps out, smoothing her dress down while giving you a good look at her cleavage, and tilts her head up, inviting you to kiss her lovingly...which you do with hungry lips. You stand there, letting the moment grow, feeling her curvy body crushed against yours, her tongue lashing out in little loving licks meant to inflame your desires. The kiss stretches out, lasting a full minute...and then two. During the third minute of having Shelly wrapped up in your arms, you reach your limit and break apart, taking her by the elbow and guiding her through the front door of your house.

As soon as you step inside, a light clicks on and you almost jump out of your skin. Turning to where the dim bulb is burning, you see your mother calmly sitting in one of the plush armchairs of your living room, a book in hand and a pair of reading glasses perched at the end of her nose. She must have fallen asleep waiting for you, as her eyes are a little hazy as she clambers out of her seat and walks toward both of you. She's wearing the same outfit as she did in the kitchen this morning, a silken robe tied so loosely at the waist that you can see generous portions of her big breasts on top and a pair of black panties on her bottom.

Despite the fact you're about to fuck your sister, you can't help but appreciate the the beauty your mother is recapturing, helped in small part by your dreaming abilities. Apparently Shelly has the same thoughts because you catch her eyes wondering across your mother's stacked body with barely contained envy. Jesus Christ, you think. Just how attracted to mom is Shelly? Maybe her whole **** fetish isn't just focused on me. Or maybe she's just plain bisexual. Scarlett certainly intimated that the two of them were more than just friends....

Your mother sweeps both of you up in a bear hug and reaches up to give you both kisses on the cheek. One of her motherly mounds pops free of her robe but she does nothing to return it to its proper location and lets it hang free. "Did you have a nice date?" she asks, her voice filled with hope that things improved once you left the house. "How was dinner and the movie?"

"Well," you start trying to spin the story so that it didn't sound as depraved and sex-filled as it had been, but it's not easy with her boob exposed like that. "Dinner was great, although I couldn't really describe anything I ate because I was so focused on Shelly. She looked so gorgeous I couldn't take my eyes off of her the entire time and I got more than a few jealous stares from the other guys in the room. As for the movie, we cut out about halfway through because we were getting distracted by...other interesting developments."

Your mother blushes slightly and you can tell she knows exactly what those 'interesting developments' probably entailed. She nods shortly, her blond hair sweeping across her shoulders like a wave, and places a hand one each of your shoulders. "Well, I just wanted to let you know that I cooked a very special meal for your father tonight; his favorite meal in fact, steak and potatoes." Her eyes sparkle as she continues. "Plus a very nice wine...liberally sprinkled with some of my crushed up sleeping pills. He trundled off to bed shortly after eating and has been snoring like a hibernating bear and I doubt he'll wake up, no matter how much noise your...activities tonight will cause."

Your mouth drops open as your mother describes drugging your father with the express purpose of letting you and Shelly fuck to your heart's content. First, that she's so accepting of your relationship that fully understands and welcomes what's going to be occurring shortly, and second, that she took deliberate steps to make sure you wouldn't be disturbed.

Your sister is the first to react, squeezing your mom in another embrace and kissing her repeatedly on the cheeks and mouth...and unless your eyes aren't working properly, surreptitiously copping a feel of her naked breast.

Your mom waves off your sister's thanks and and starts pushing you toward the stairs. "Alright, alright, I get it," she says. "Your mother's an amazing woman, I know. Now, go have some fun." Her tone is still motherly, but you also know a command when you hear one and you pull Shelly up the stairs, where she redirects you to her bedroom, which is further from your parent's room then your own. No need to poke the bear unnecessarily, you realize.

You step in and she closes the door behind you with a tiny click. For a second, both of you stand there, neither moving, barely breathing. Then Shelly reaches behind her back and, never taking her eyes off of you, slowly lowers the zipper on the back of her dress. She shrugs the dress from her shoulders, the fabric briefly stopped by the protuberance of her massive rack, and then shimmies it the rest of the way off, your mouth watering as more and more of her body comes into view. You've seen parts and piece of it all night, but observing it in its full glory is an awe inspiring experience. From her exquisite and pure face, to her stupendous, gravity defying breasts, to her toned stomach and flaring hips, to her clean shaven pussy mound, everywhere you look you see perfection. And she stands there, unashamed at her nakedness, letting you drink in her entire beauty.

Then it's your turn to let your jacket fall to the floor, quickly followed by your tie and dress shirt. You feel your sister's gaze linger over your muscled chest--another new byproduct of your experiences within the dream world. The tip of her tongue darts free when your hands fall to your belt, tugging it loose and unbuttoning your pants in one smooth motion. You push everything down at the same time, sliding it past your erection and letting it puddle on the floor in one heap. Her nostrils flare as she has her turn staring at your nude body, drinking it in with a growing need and unadulterated arousal.

Now that the time has gone, all doubts have fled and your commitment to each other is wordlessly communicated between you both.

Shelly steps forward and you allow yourself to be led to her bed, where she gently pushes you onto your back and climbs on after you, her hanging breasts dragging luridly up your legs as she does. She lingers at your crotch, breathing in your scent, before your cock slaps lightly against her slopes as she continues her journey up your body. By the time she reaches her final position, straddling your waist like a cowgirl, your dick is straining toward the sky like a beacon. She reaches below to guide your tip to her entrance and then looks up for one final time.

"I love you," she says simply.

" I love you too," you reply.

And then you're buried to the hilt inside your sister's forbidden pussy, her hips moving fluidly to impale herself on your rod. "Oh, fuck me!" she cries, stunned at the feeling of having you stretching her inner walls so sweetly. "I knew you were big, but I can't believe how full you make me feel!"

Shelly starts moving unhurriedly, her years of yoga showcasing themselves as she maintains an insane amount of control over her hips and stomach as she rides your pole. You feel every inch glide in an out of her cunt as she rises and falls, surrounding your dick with a velvet sheath that is gradually, maddeningly driving you wild. Even with her slow gyrations, her soft breasts jiggle above you like twin melons, delicious and ripe. Unable to control yourself, your hands fly up to them, cupping them and smashing them together they're one solid mass of boobflesh.

Your sister moans at your touch and throws a sultry glance down at you. Her curled blonde hair floats on the air as she says, "Oh god, I've wanted this for so long! To have you in my bed, your hands touching my body, playing with my tits, your hard dick plowing my pussy! I can't believe this is happening. Please tell me this isn't a dream!"

You pinch her nipple, bearing down hard on it and a painful shriek erupts from her mouth, but it's tinged with excitement as well. She glares at you and you feel her cunt wrap even tighter around your shaft in retaliation.

"Trust me," you assure her, chuckling amusedly. "This isn't a dream. I would know, I'm kind of an expert on these things."

Shelly growls and looks about to respond when you grab her by the waist and thrust powerfully up inside her, the first time you've done anything besides letting her set the pace. Her eyes flare back for a second but then she tumbles forward like a tree felled by a lumberjack, her breasts captured between your bodies and her hands thrown out to catch herself. Taking over, you pound away at her pussy, giving her your entire dick in thrust after thrust. She begins to lose control, her eyelids fluttering rapidly and her body shaking like a leaf in the wind.

"I'm cumming, I'm cumming, you're fucking making me cum! Oh shit, it's fucking huge, I can feel it! Please, cum with me, shoot inside me, I want it all, please, please, PLEASE! Give it to me! Ah...fuck, I've never...I can't...ahhhhhhhhh, FUUUUUUUUUUCK!"

Your simultaneous orgasm sends waves of refined bliss into your core as quickly as your balls erupt, spraying your brotherly seed into your sister's pulsing twat. She screams as the first shot splashes inside her, shuddering even more violently. Each subsequent load provokes a weaker squeal. By the time you're completely drained, you're extremely thankful that your mother had the forethought to **** your father because you doubt anyone could sleep through Shelly's loud orgasm.

Your sister lift her head from your chest, her hair in a fuzzy mess around her face, and you can practically hear her purr in delighted exhaustion. "That was amazing," she tells you, lifting off your conjoined crotches and sliding alongside you until she can kiss you on the tip of your nose. "I've never experienced anything remotely as intense before. I think I can safely say that was the best sex I've ever had."

"Me too," you tell her, unable to muster up much more than that. You're in complete agreement. All the girls you've slept with pale in comparison to your beautiful sister and it's not even close. I'm one lucky bastard, you think with a deep sigh. The warmth of her body laying against yours draws you low and you feel your eyelids droop.

And then you feel Shelly hand coaxing your semen and cunt soaked cock back to an aroused state. You groan as it rises again, sore from the two previous climaxes already tonight. When you **** your eyes back open, your sister is grinning impudently. "You can't go to sleep already, big brother. You've had my mouth and tits at the movie theater and my pussy just now. By my count you have one more hole to fill before your job's complete."

As the meaning of her words permeate your sex-dazed brain, your dick springs to immediate life, the blood rushing to it in a dizzying wave. It's almost painful how hard you've become in so short a time. You search her face for some sign of teasing but you don't see anything. "Are you sure?" you ask, your voice cracking like a boy's.

In response, Shelly turns to her bedside table and pulls open a draw, rummaging through its contents before pulling out a pink bottle of lube. She waves it under your nose. "What do you think?"

With a flick of her thumb, she uncaps the top and squeezes out a large dollop of clear goo. "We're going to have to go slow and be careful though. I've never done this before and you've got a giant cock, whereas my asshole is quite tiny. We'll want to coat you and me pretty liberally, I think."

She returns her hand to your prick, slathering it with so much lube that it drips past your balls and pools in messy puddles all over her sheets. Your sister probably lingers a little longer than necessary, enjoying the feeling of your erection in her hands. But finally, she hands the bottle to you and flips on her stomach, propping a pillow beneath her hips to lift her ass in the air for easier access. You squash it over her rear end, letting the slick substance coat her glorious cheeks until they shine. Then, after scooping up a bit with your forefinger, you delve into her crack and find her tight backdoor, pushing gently until the tip slides home.

Shelly gasps but doesn't ask you to stop, so you wiggle you finger inside her, sliding in past your first knuckle and then your second.

"Fuck, that feels really weird...but keep going." Her words are strained but determined. You begin to piston your finger in and out of her anus, working to get it ready for something much larger. Lining up a second finger, you wedge it in alongside the first, stretching her butthole until you can actually see her inner walls. "Oh geez, that's...that's not too bad. I think I'm ready to try something a little bigger."

Your weariness from a few minutes ago is forgotten, a new, untapped well of energy springing forth as you prepare to engage with one more taboo with Shelly. She reaches back to spread her cheeks, opening herself up so so you can focus on getting your thick rod in her backdoor. You place your tip at your puckered hole and push forward, meeting with so much resistance that you have to pull back. Shelly wiggles her ass in encouragement and you try again, leaning forward to let your whole weight assist in breaking through the small ring of her anus. The mushroomed head sticks, not moving any further. Then, letting her breath flow out of her lungs, your sister relaxes just the slightest bit more and the first inch of your cock slides home.

"Oh shit, oh shit," Shelly moans. "Hold on, let me get used to it." Taking big breaths, your sister adapts to your big dick splitting her asshole. Meanwhile, you take the lube and coat the junction of your nether regions, lubricating everything even more. Finally she nods her head and gently but firmly press forward.

With methodical precision, you're able to insert about half of your cock before you can't go any further. She tosses her hair to one side and glances over her shoulder, determination spread across her face. "Good. Now fuck my ass!" she tells you, pleasure and pain mixed together.

Starting with short, steady strokes you fuck your sister's ass, sending vibrating ripples across her plump rear end as you do. The waves are almost hypnotic, captivating your eyes in their undulating motions. You've never been much of an ass man, but watching her cheek jiggle and shake as you spear her butt is intoxicating. You can't help but reach out and grab that writhing flesh, digging your fingers in until they disappear into that soft surface. And then, without thinking, you slap one of her cheeks.

Shelly's response is immediate. Her head is thrown back and a piercing cry echoes throughout her small room. "Do that again!" she shouts. "Spank me again!"

Shocked, you do it again, harder this time. Another shout from your sister, encouraging you to slap her over and over. Soon, the sound of your hand hitting Shelly's asscheeks dominates your fucking and your red handprint spreads across her tender rump in crooked, ill-formed patterns. Even more surprising, the spanking seems to have eased up her asshole and your dick is penetrating almost to the three-quarters mark. Additionally, Shelly libido seems to have overtaken her discomfort of being assfucked and she's enthusiastically push back to meet your every lunge.

"I'm yours, big brother, in every way. I'll be your lover, your slut, your whore, your cum dumpster, whatever you fucking want me to be. Use my ass, my pussy, whenever you want. Make me your bitch, fuck my friends...hell, fuck our mother too. I don't care as long as you keep fucking meeeeeeeeee!"

Your sister's complete submission to your dominating assfuck and spanking brinks you to the brink and over. With a second to spare, you pull out of her ass and spin Shelly around. You cock pulses a couple of times and then let's loose, fulfilling the promise you made to your sister at the restaurant, that you'd cover her face with your sperm before the night was over. She obediently turns her face upward and accepts every bit of semen you have to give her, until her nose, chin and lips have white globs hanging from them in thick, sticky strings. Her tongue runs in circles, trying to lick up everything she can reach but her face is too plastered for her to get everything. You grab some tissues from nearby and help her clean up the rest of the mess.

Afterward, both of you lie in her bed, grinning like idiots and holding each other like the lovers you've finally become. Words aren't needed, both of you comfortable just to sit in silence and reflect on recent events. I never knew Shelly had such submissive tendencies, you think, remembering her reaction when you slapped her ass. And what was that about her encouraging you to fuck other girls? Could she really be okay with that.

Before you can pursue either of those threads any further, your eyes slide shut and you tumble into a deep sleep.
