Bob Hardin lay on the over-stuffed couch in his sister's apartment, pretending to be asleep. In fact, he'd been wide-awake ever since someone padded into the living room, knelt beside the couch and gently unsnapped the waistband of his shorts, exposing his semi-erect dick.
It had to be Robin; there was no one else in the apartment. But what the hell was all this about? She'd been asleep a few minutes ago when he'd gotten up for the obligatory morning piss. There'd been a moan coming from her bedroom and he peaked in the half-open door to see if she was okay. What he saw in the light from the hallway made his piss-hard throb with pain.
Robin lay on her back, apparently asleep, but with her head moving slowly from side-to-side as she smacked her lips. From many a night spent together as kids, Bob knew she had to be dreaming.
The old football jersey of his she'd swiped and now used for a nightshirt had bunched around her waist. Like everyone else in their family, Robin was tall, nearly six-foot in heels, and had the legs to match. They were slightly parted and seemed to draw his gaze up to a muff only slightly darker than her long, honey-blonde hair.
Unlike his buddies back in high school, he'd never had the hots for his twin sister. Oh, they'd teased and picked at one another while growing up, even practiced kissing a bit. But he liked short, cute girls. Besides, Robin was his sister.
After another soft moan, Robin rolled over. Bob stepped back, but didn't move away. She now lay with her bare bottom thrust toward the ceiling. Bob had to stifle a moan of his own. Talk about your earthly delights. Sister or no sister, Robin had one incredible ass.
Why in the hell would any guy, even that weirdo ex-husband of hers, blow such a sweet deal? But that's just what he did six months ago.
Bob had been overseas at the time. When he came home last week, Robin came home from college to see him. Everyone in the family could tell she hadn't gotten over her divorce. When she urged him to make the three-hour drive back to her school for an Earth Day rally, he resisted until something convinced him she really wanted to talk.
He'd been right. They talked all the way back and for hours afterward. Amid a lot of tears, he learned why her husband had walked. When he started beating on her for the second time, Robin pulled out the snub nose .38 Special Bob had taught her to use and started counting down from ten. By the count of three, she'd been alone. The next day, she filed for divorce.
After hearing what happened, Bob wanted to go find the guy and pound him soft. But Robin said, no, that it would only make her feel worse. She'd been right, of course, and he'd agreed--still.
He'd sighed, taking one long, last look as his sister's fantastic ass and then, unable to ignore the insistence of that aching piss-hard any longer, forced himself to head for the bathroom.
He'd almost dozed back off on the couch when he first heard the soft movement. For some reason, he decided to keep his eyes closed.
When fingertips reached inside his boxers and gently extracted his suddenly very erect shaft, he damn near jumped off the couch. Long, thick, silky hair began caressing his skin. Moments later, soft lips encircled the head of his stiff cock and down the shaft until its entire length had been enveloped in the moist, perfect warmth of a loving mouth.
He moaned with pleasure, opened his eyes and watched the lips making slow, sensuous trips up and down his shaft. Bob didn't move and wasn't even sure he could. This was so unexpected, so fantastic, so unreal. His sister had woken him with a blowjob--and what a blowjob. "You really know how to get a guy up in the morning."
Robin said nothing, just nodded and continued bobbing her head up and down the length of his cock. Somehow, Bob found the strength to move one hand and gently stroked her hair.
As great as this felt, he wanted more. It took a second, but he managed to stop Robin and then pull her to him for a kiss. This one was no childhood practice drill. Tongues, lips, teeth all played their part. When they parted, Bob looked into Robin's blue-eyes. "Climb on board. Let's have each other for breakfast in bed."
"What a lovely way to start the day," said Robin. Their bodies molded without effort into a comfortable 69 position. Robin resumed her work on Bob's cock while he buried his face into those dark-blonde curls he'd admired earlier that morning. For the first time, he tasted his sister's sweet pussy.
To Bob, oral sex was a natural, enjoyable extension of lovemaking. He'd "gone down" on several girls. For when it came to oral sex, he got almost as big a charge out of giving as receiving. As he savored the aroma and taste of Robin's pussy and the feel of his cock sliding in and out of her warm mouth, he knew from experience this was the finest kind of oral sex.
When it came to great tasting pussy, Robin had to be in a class by herself. No other pussy he'd known even came close to equaling her almost sweet, feminine flavor. From this moment on, he'd be more than willing to eat her anytime and anywhere she wanted, and do so until his tongue wore out.
That wasn't to say she didn't give good head. In fact, Bob feel himself beginning to build toward a climax. To get Robin to come when he did, he concentrated on teasing her swollen, sensitive clit.
His efforts produced a muffled gasp followed by Robin's smooth thighs squeezing his head. Wrapping his arms around her waist, he pressed his face against her savory pussy and swirled his tongue into its warm depths.
Moments later, his load raced up his cock and exploded into his sister's waiting mouth. Through the haze of his own orgasm, he felt her tense, then press her pussy down against his face as her warm juices began flooding over his face.
Their climaxes seemed to last forever. Every time Robin's body began to relax, Bob would lick her clit and she'd jerk and shiver with pleasure. Meanwhile, she kept her lips locked around his cock, swallowing all it produced and trying to milk out more.
Eventually, their passion ebbed away. Robin released Bob's cock, then turned around and kissed him deeply, running her cum coated tongue past the sweet pussy juice covering his lips. For the next few minutes they kissed and hugged, enjoying the after-glow and after-taste of their loving.
They both could feel the beating of the other's heart begin to slow. When Bob started to say something, Robin put a finger to his lips. "Let me talk," she said, and he nodded.
After a moment, she kissed him again, and then smiled. "Thanks big brother. I needed that."
"Well, after all, you are five minutes younger than me. It's my job to look after my kid sister."
"And you always have. But I'm serious. After what happened, you know, I felt dead, like nothing mattered. I kept wondering how I could have ever thought I loved that bastard. Since he left, it's been all I can do just to make it to classes. I sleep too much, don't go out, and I've gained weight."
Bob ran his hands down Robin's back and gave her soft bottom a gentle squeeze. "Believe me, if you've put on a few pounds, they've all gone to all the right places. No bullshit little sister, you have a body to die for. And this fanny of--."
Robin didn't let him finish. "You're sweet. But I haven't wanted to be with people since the divorce, much less make love. But last night, I dreamed about you and me, doing this. When I woke, I just had to make it happen, even if it meant holding my .38 on you."
"I much prefer the method you picked."
They both smiled. Then Robin looked serious. "Do you think what we did, you know, incest, do you think it's a sin? I'm not sure. But if it is, I don't know, maybe just oral sex isn't quite so bad."
"Oh, my poor messed-up little Sunday School star. Like you said before, you needed this. If our making love is a sin, then believe me, I've committed many far worse."
"Don't tease me, Bob. I'm serious."
"So am I. Look, I honestly don't believe incest is a sin. But if it is, I just hope we'll suffer whatever punishment we deserve, together."
They laughed, kissed, then got up. While Robin went to the bathroom, Bob got coffee and toast started. After breakfast, neither one mentioned the bedroom. Robin turned on the stereo and they went back to the big couch that had once belonged to their grandmother.
Their bodies seemed to mesh perfectly on the soft, plump cushions. While the foreplay was good, both wanted more. They watched, spellbound, as Bob's cockhead moved between the lips of Robin's well-lubricated labia. For just a moment they looked up at one another, sensing the special meaning of what was about to happen.
In a low, husky voice tinged with excitement, Robin said, "Okay, let's do it, oh--." Words gave way to a long, pleased moan as the thick shaft disappeared into her body.
They quickly got into an almost effortless rhythm with Bob's cock gently stroking into Robin as she raised her hips to meet each downward thrust. She nibbled on Bob's ear while gently stroking his back. A series of small, exquisite orgasm began racing through her body. Each time one struck, she would pull Bob close.
When the passion passed, he would slow his pace to the point where he was barely rocking back and forth in her inflamed, sensitive pussy. When she recovered a bit, he would return to his previous, measured pace.
After Robin had experienced yet another orgasm, Bob started building toward his own climax. "Must be my turn. I'm about to come." He sounded almost casual.
Robin gave him a deep kiss followed by a mischievous smile. "Tell me how it feels."
"That, uh, might not be easy. But I'll try."
For a moment, Bob paused to collect his thoughts. "My nuts, they're getting tense. My cock feels like it's going to, oh, that's nice, pop any second. I'm coming. Oh shit. Now! Oh shit, yes! Deep inside you. It's pumping. Oh shit! You're squeezing. Oh, oh, ah!"
Bob's description of his climax pushed Robin to another one of her own. As a long, satisfying orgasm rolled through her writhing body, she wrapped her legs around his butt and tried to pull him even deeper into her churning pussy.
They remained together kissing, talking, feeling one another. After one especially passionate kiss, Bob began a slow hunching motion. "You're an optimist," said Robin.
"Hey, you never can tell what might turn up." Before long, it became obvious the answer was Bob's cock. This time the lovemaking was slow and sensuous. At one point, they kissed and slipped tongues in and out of each other's mouths in time to Bob's thrusts. Later, Robin nibbled on his neck and ran her tongue inside his ear.
That moved things into a higher gear. Bob positioned Robin's legs on his shoulders and began using faster, deeper strokes. The new position seemed to push all the right buttons for Robin. The orgasm that followed took over her existence, filling her with a bliss that wiped away everything else. The only reality she knew was Bob and the unyielding cock inside her body. She clutched at him, at that reality, as the orgasm crested and warm fluid flooded from her pussy.
The feel of Robin's body shaking with passion and the incredible sensation of her juices soaking his balls, pushed Bob over the edge. Like her, his climax seemed to last forever. Load after load of cum blasted deep inside his sister's writhing body as they clung together and rode out the storm of their emotions.
Afterward, they lay motionless and felt the passion ebb from their bodies. Neither seemed anxious to break the physical contact and end what had been very special loving. Then Robin glanced at the clock on her TV. "Oh, my God. Do you realize what time it is? We've better get a move on."
"Time flies when you're having fun," said Bob.
"Yes, it does. But I promised some friends I'd help run an information booth at the rally. Come on, Earth Day calls."
"I'm having a fine celebration right here. Just give me a few minutes and I'll show you a rally. Honest."
"I'm sure you would. And I'm counting on that. But later, honest. I promised my friends I'd be there. Besides, some good bands will be at the concert and I'm hungry." Having wiggled out from under Bob, she stood and looked down at him. "I just realized, this is the first time since, you know, since he left, that I've wanted to do anything. Believe me, big brother, we're not finished for the day."
The rally proved to be fun. There were more than enough people at the Clean Air booth, so Robin and Bob went off exploring. The concert started in the late afternoon. They had staked out a shady spot near the edge of the crowd and settled down on a plaid blanket Robin brought to listen to music and drink wine.
It began growing dark with the concert about half over. Bob turned to say something to Robin, and saw her staring at him. Neither said a word, but knew by some genetic chemistry they both wanted the same thing.
Bob asked, "Where?"
Robin stood and tugged on the blanket. "Bring the wine and follow me. I've done a lot of volunteer work in this park and know a place we can be alone."
Minutes later they were in a small, leaf-covered clearing behind thick shrubs but still within sound of the concert. Slowly, almost tentatively, Bob put his hand under Robin's chin, pulled her gently to him, and kissed her soft lips. With a sigh, she molded her body against his and opened her lips. As they kissed, Bob stroked her long, thick hair with one hand. With the other, he began unbuttoning her cotton work shirt.
When he finished, Robin pulled them down onto the blanket. As they kissed, Bob stroked and kneaded one of her soft, creamy breasts and toyed with its sensitive nipple.
After pulling the shirt open, he leaned over and locked his lips around that hard, tasty bud. Robin gasped and placed her hands on the back of his head. As he sucked, licked and nibbled, the nipple seemed to swell in his mouth. He began massaging the other breast until its nipple had also become stiff with excitement.
