Sis's milk

Sean pulled the rental car to the curb in front of his sister's house and parked. Pulling a small duffel bag from the back seat, he started up the walkway to the front porch.

He hadn't seen Cynthia in a little over six months, and the last time he'd seen her, she had looked as though she'd swallowed a basketball. A month later, Cyn had given birth to Lisa, his first niece.

Let's see, he thought, that would make Lisa about five months old, now!

He should have made it back to see his niece earlier, but living on the opposite coast made the trip an expensive one. And he'd used the last of that year's vacation days on his last trip home. Thankfully, the new year had brought a new batch of vacation days, and he'd managed to Sean this trip to let him kill several birds with one stone: visit with his parents, visit his sister and see his niece for the first time, and also attend his best friend's wedding. A side benefit was that he'd be able to help Cyn paint her husband's den while he was away on a business trip. She was sure that Tom would be surprised by the renovation, when he returned home.

Stepping up to the door, he rang the doorbell and heard Cynthia's voice through the screen door, inviting him to come in.

Pushing the door open, he stepped into the foyer.

"Cyn?" he called out.

"I'm here, in the living room," she responded loudly.

"Uh, okay," he said walking toward the sound of her voice.

Stepping into the living room, he stopped dead in his tracks, staring at his sister sitting on the couch. Sitting on the couch...nursing Lisa. With her blouse completely unbuttoned and both of her huge breasts bared.

Sean's eyes flared open and his chin dropped as he stared at his sister. She had Lisa's mouth pressed against one of her big, beautiful breasts as she sat lovingly looking down at her baby. Little Lisa was holding onto the huge, milk-filled udder with her tiny hands, hungrily sucking away at the nipple as Sean looked on in fascination.

Then, Cynthia looked up and saw him staring at her with a shocked look on his face.

"Oops...sorry...I forgot," she laughed, draping her shirt over her breasts, covering one and partially covering the other, from Sean's peering stare.

"Uh...uh...that's...that's okay," he said, trying to swallow the bale of cotton that had mysteriously appeared in his mouth as he tried to calm the stirring he felt down in his jeans. "I...I just wasn't expecting that. They...They're so big.

"Yeah, that's what happens when you've got a kid to feed," she smiled up at him.

"Really big," he muttered.

"I've got everything set up in the den, if you want to go ahead and start. Let me just finish nursing Lisa, and I'll be in to help you in a few minutes."

"Okay," he said, taking another quick glance at her partially exposed breast as he set his overnighter on the coffee table.

He couldn't believe how big her tits were. The only time he had seen them before was when they were kids. They were tiny, back then.

"Uh, the den," he nodded, finally tearing his eyes away from his sister's breast as he saw a slight blush color her cheeks.

"Sorry," he apologized, blushing himself as he turned and started for the den.

"That's okay," she called after him, "It's my fault, really. I should have nursed her earlier."

Sean had arrived in his painting clothes, so he had finished one wall and was starting on a second before Cynthia came strolling into the room. He looked away from his task to see that she was wearing only an old paint-splattered shirt and panties. The hem of the shirt hung down in the front and back, obscuring most of the view, but the shirt arched up in a curve on the sides, revealing the waistband of her panties where it crossed her rounded hips. The shirt was also thin enough for him to note that she wasn't wearing a bra. Even if the pendulous swing of her breasts wasn't noticeable -- which it definitely was -- her nipples, still erect from the sSeanulus of nursing, were poking blatantly against the worn fabric.

"Sorry, I took so long, but I wanted to put Lisa to bed so we wouldn't be interrupted," she told him. "You can get to know her tomorrow."

"Yeah, that'd be nice," he smiled, glancing down at the exposed cleavage peeking out from between the edges of her shirt and her thrusting breasts. "I got a lot done anyway."

"Yeah, I see. I'll help you do another wall, then I'll start on the trim," she said, ignoring his prying look as she bent down and picked up her roller and paint tray. "I've ordered a pizza delivery, for dinner."

"You sure look nice, Sis," he told her. "You look a lot different than you did the last time I saw you."

"A half-hour on the treadmill, every day," she said, feigning wiping sweat from her forehead. "It'll keep you fit and trim."

"Well, I must admit, it seems to be working," he smiled.

"Why, thank you," she laughed softly, noting the slight blush coloring her cheeks.

Watching his sister move about with her giant, milk-laden breasts undulating heavily under the shirt soon had Sean in a highly obvious state of arousal. He tried his best to keep it hidden by facing away from her while he painted.

Two hours of steady work had the walls and trim covered in new paint. The pizza arrived and they devoured it quickly. Their intended return to painting was delayed, however, when Lisa awoke from her nap and announced -- with a loud wail -- that she needed some attention.

Motioning for Sean to follow her, Cynthia led the way to the nursery. Lifting her infant daughter from the crib, she placed her in her uncle's unsure arms.

"Relax, honey," she giggled when Sean looked up at her with somewhat terrified eyes. "You can do it; it's instinctive. And it'll be good practice, for when you finally have a wife and baby of your own!"

"Oh -- you mean this look on my face?" Sean shook his head. "It isn't fear. It's more like lack of knowing what to do. I can smell it, even if you can't. I think she needs a change of diapers."

"Then we'll give you a bit more practice," Cyn laughed. "Put her over there, on the bassinette, and I'll get the baby-wipes."

With Cynthia looking on with an amused grin, Sean followed her instructions and handled the diaper-change rather well, all things considered.

Then, of course, he had to endure the sight of her partially-exposed breast, again, as Cynthia nursed Lisa before putting her back to bed for the night.

Shortly, the nursing was finished, and Cynthia buttoned the blouse again, though Sean noticed one less button was fastened than earlier, and they returned to their task of painting. An hour later, they were finally finished and stood looking around at their handiwork.

"Looks great," Cynthia beamed, looking over at him. "We make a great team..."

"Yeah, maybe we ought to set up a business," he laughed. "But first, I think you'd better clean up. You look like you've got green measles."

"Aren't you the pot, to call the kettle black," she laughed back at him, running a fingertip down his paint-splattered cheek.

Impulsively, Sean grabbed her hand and brought her finger to his lips. Holding it gently pressed against them, he gave the tip of her finger a lingering kiss.

Questioningly, she looked into his eyes, her cheeks flushing once again. Then he smiled and let go of her hand.

"Why did you do that?" she asked.

"I don't know," he smiled. "I don't know...it just seemed like the thing to do at the moment. Sorry if it upset you..."

"No, no, it's okay," she said, taking a step back as her big tits swayed ponderously under her shirt. "It just took me by surprise...that's all. It was a sweet thing to do."

"Well, who's first? You or me?" he asked, stepping back over to the paint buckets.

"What do you mean?" she asked, with a puzzled look on her face.

"You or me...the shower?" he said, leaning down and dropping his brush into a bucket of water.

"You, you, I guess. Yeah, you can go first," she said, following him over to the buckets. "I'll clean up this mess while you go clean yourself up."

"Okay," he grinned, standing up and departing toward the bathroom.

Grabbing his overnighter on the way, he hurried down the hall to the bath.

Showering, he was torn between whacking off to get rid of his obvious erection or saving it for later, when he was in bed. Finally, after a few strokes, he decided to do it later, after Cynthia went to bed. With a grimace, he turned on the cold water and stood under it until his cock finally began cooperating and wilted back down to a much more manageable size...

Once he was dried off, he quickly slipped his pajamas and slippers on before heading back out to the living room. Stepping into the living room, he saw that Cynthia was sitting on the couch waiting for him. She had made a fire in the fireplace and had a bottle of wine sitting on the coffee table. Beside the wine sat two glasses. One empty and the other, half full.

"I thought maybe you'd drowned or something," she laughed softly, getting up from the couch.

She had turned the lights down low and the reflection of the flames from the fireplace sparkled off her warm, hazel eyes.

"Sorry," he grinned. "I didn't mean to be gone so long."

"Don't worry about it," she grinned back at him, stepping around him and heading for the bathroom. "I'll be back. Make yourself comfortable and have a glass of wine..."

"Okay," he grunted, watching the sway of her hips under the shirt as she strolled away.

Sitting on the couch, sipping his wine, he watched the flames frolic in the hearth, sending shadows dancing on the walls in the dim light. He was feeling warm and cozy, partially due to the fire's warmth and partially due to the wine. A curious inSeanacy filled the room, as he sat on the couch while his beautiful sister was down the hallway in the shower.

Naked.

Not that he had experienced the inSeanacy of marriage, but this felt a lot like what he imagined life with the right woman would be.

Suddenly, he felt another stirring down in his pajama bottoms. The thought of her standing under the warm water, letting the spray caress her beautiful milk-laden tits, immediately took its toll and his cock was once again fully erect...and ready.

Ready for what, he angrily asked himself. She was his sister, for Christ's sake!

Thinking back, he remembered their closeness as children. What a long time ago that had been. Now she was twenty-six. She was married, and had a baby. He was sixteen, horny all the time and always looking for a piece of pussy no matter the source. He had to admit, he still loved her. And he knew the way he felt toward her. But that platonic love for her could easily cross the line and become something much more.

Much, much more.

Then that day ten years ago came rushing into his mind...

She had been twenty and he had been ten. They had been messing around in their Dad's work shed out behind the house doing something. What, he couldn't remember. He had just been entering puberty, and was beginning to notice that girls were different than boys. Different in such a nice way. He had noticed that Cynthia's breasts were starting to stick out against the front of her dress, and he felt a new and curious need to see them.

The memory of that incident played itself out in Technicolor, on the wide-screen of his mind...

"How come your, uh, those are sticking out like that?" he asked her as he pointed at the bodice of her dress.

"Those are my breasts, silly. They're getting bigger," she smiled condescendingly. "I'm growing up."

"Can...can I see 'em?" he hesitantly asked.

"Uh, why? Why do you want to see my breasts?" she asked him.

"I don't know," he grinned. "I just want to see them."

"We're not supposed to do stuff like that," she mumbled, stepping over to the window and nervously looking out towards the house.

"Oh, come on...let me see 'em," he sniggered. "I'll show you my, uh, my penis."

"Why would I want to see your...your penis?" she snickered, turning to face him. "Besides, I've already seen one."

"I don't know," he muttered. "I've never seen a girl's tits, or pussy, either. When, when did you see a guy's...a guy's pecker?"

"A couple of weeks ago. I saw Billy Johnson's," she said. "It was pretty big and it got all hard and stuff when I showed him my tits."

"Well, if you could show Billy Johnson, you could show me, can't you? If I show you my.penis?"

"I don't know," she giggled. "How big is yours?"

"Uh, five...five inches when I make it, you know, hard," he said. "Want to see it?"

"Maybe," she smirked. "But first, I'll show you my titties and maybe that'll make it hard, like Billy's got when I showed my tits to him. Then we can measure it!"

"Uh...okay," he grinned, looking down at her pubescent bosom.

After another quick check out the window, she reached up and began unbuttoning her little spring dress.

"Do you wear a bra...uh, brassiere?" he asked her, awkwardly gawking down as he waited for her to bare her breasts.

"No...no, they're not big enough yet," she said, "but they're getting bigger every day."

"Oh," he mumbled, not knowing what to expect.

Finally, with her dress unbuttoned all the way down to her waist, she slowly spread it open to reveal her small, budding breasts.

Even then, he remembered, he had felt a stirring down in his cock. He couldn't explain it. Seeing her budding breasts just made him feel all hot and strange inside, and his cock started to get hard.

Her breasts, if you could call them that, were small, rounded mounds of pink flesh, each tipped with a small, pea-sized nipple that jutted out, hard and swollen.

He hadn't recognized it, back then. Now, eight years later, he understood that it was her own excitement that had aroused those little pebbles...

"Wow," he grunted. "Can I touch one?"

"Just a little," she murmured.

Inquisitively, he reached out and fingered the jutting bud, delicately running his finger over it. She watched his finger trace the outline of her quarter-sized areola and then tickle her jutting nipple again.

"Okay," she mumbled, pushing his hand away and covering herself again as she began buttoning her dress. "That's all you get to do."

"Uh...if I show you my, my dick," he grinned at her. "Will you show me your...your pussy?"

"Maybe," she grinned, coyly, "but show me your cock first."

He couldn't explain why, but his cock was now hard as a rock. This was all so new to him. New feelings, new emotions, uncharted territory."

"Okay," he said, unsnapping his pants. "How big was Billy's...Billy's peter?"

"I don't know," she giggled, "I didn't have a tape measure with me. But it looked really big. Too big to put it in my little pussy."

"Have you ever had...had a peter in your pussy?"

"No," she said emphatically. "Have you ever put your peter in a girl's pussy?"

"No...no..." he said, grinning shyly, pushing his pants down. "Maybe we could, uh, you know, uh do it later."

"I'll have to see it...see how big it is, first," she murmured, staring down at the bulge of his cock jutting out against his white, cotton shorts. "It looks awful big to me. Maybe too big."

"Well?" he grunted, shoving his jockeys down off his stiff prick.

"Wow! It is big...even bigger than Billy's!" she said, but he knew that his cock was small. Still staring down at his cock. "Can I touch it?"

"Uh, yeah, uh, sure," he said, thrusting his hips forward, bringing it closer to her.

"I...I never saw one as big before," she lied again, tentatively reaching out and running her fingers down his swollen, four-inch cock. "I don't think it will fit in my pussy."

"Let me see it," he said. "I want to see it. See your pussy and see if my cock will fit in it."

"Wait, wait a minute," she huffed, wrapping her hand around the thick shaft of his oversized cock. "It's so big."

"Come on...come on," he whined. "Let me see. Let me see it."

"Oh all right," she muttered, nervously looking out the window toward their house. "We can't let anybody catch us doing this, though."

"I know...I know," he grunted. "Why don't your pull your panties down while I watch out the window and make sure nobody is coming."

"Okay," she said, pushing her father's tools aside and crawling up onto his worktable. "But keep watching and don't be looking at me until I tell you."

"I will...I will, just hurry up," he muttered, watching the back door of their house.

"Okay...okay, you can look," she finally said.

Sean turned and saw she was lying in the middle of the table with her knees splayed out, and her white, cotton panties wrapped around her ankles. As she did, her pubescent pussy defiantly stared up at him from between her skinny legs. A soft tangle of sparse brown hairs encircled the knife-slit gash that bisected the mound of flesh between her legs as he gazed down at it in wonder and awe.

"Can I touch it?" he breathlessly asked.

"Oh, I guess, but just a little bit," she whined.

"Where's your...your clitoris, your clit?" he asked, gently running his fingertips over the tiny, soft lips surrounding her secret place.

"Here...this, this is it," she mumbled, running two fingers down the slit and peeling the fleshy hood back off her miniature clit.

"Wow," he whispered, fingering it delicately.

"It gets all tingly when you touch it like that," she murmured. "Like it does when I see your big peter."

"Can I see, can I see if my...my peter will fit?" he asked, grabbing her by the thighs and pulling her over to the edge of the table.

"I...I guess. But don't be rough...and stop if I tell you to stop...okay?" she told him.

"SEAN...CYNTHIA...ARE YOU OUT THERE..." they heard their mother cry out from the back door of the house.

"Crap," Sean cursed, grabbing his shorts and pants, pulling them up as fast as he could.

"Go...go hide," Cynthia blurted out, jumping down off the table and jerking her panties up." I'll tell her I haven't seen you and you can come in later. Okay."

"Okay...maybe later?" he grinned.

"No, this was too close. Not again...I don't want to get caught."

His eyes were closed, and a soft smile played at the corners of his mouth as the last of the incident played through his mind. He was so caught up in the memory that he failed to hear the sound of his sister's footsteps as she entered the living room.

"What are you so deep in thought about?" he heard Cynthia ask.

Dragging himself back to the present, Sean turned and saw his sister padding across the living room toward him. She had a big, white towel wrapped around her hair and wore a fleecy, white bathrobe wrapped around her body and tied at the waist.

"Uh, oh, nothing," he blushed, eyeing the swell of her breasts under the robe.

"Must have been something," she laughed softly, easing down onto the couch and leaning forward, "I called to you twice, and you didn't answer."

Unwrapping her hair, she began drying it, roughly rubbing it with the towel. As she did, her big, jiggling breasts drooped down, forcing the robe open.

Gawking down at her big breasts, he felt his hard cock twitch. He had never seen such beautiful breasts. Round, melon-sized breasts, that bobbled and danced as she continued to dry her hair. Finally, she tossed the towel on the coffee table and looked down at her exposed breasts.

"Oh...I'm sorry...I didn't know," she blushed, clutching her bathrobe closed. "You must think I'm such a klutz..."

"Uh...no...and don't be sorry. I didn't mind at all," he grinned foolishly.

The silence was deafening. There was no sound except for the crackle of the fire as Cynthia, still clutching her robe together, leaned forward and picked up her glass. Then, she turned to face him, curling her leg under her as she stuffed her robe down between her legs and laid her arm on the back of the couch.
Sean didn't know what to say to her...or do. How could he tell her how he really felt about her? How could he tell her that he really loved her like a sister, but that he wanted to love her like a man loves his woman?

"Uh, you remember that day...that day out in Dad's work shed?" he finally asked.

"You mean the day that you asked me to show you my breasts? If you could call them breasts back then...they were so small," she laughed.

"Yeah, that day," he said, gulping.

She remembered, he giddily thought. And she's even joking about it. That's a good sign, isn't it?

"Well, they sure aren't small anymore!" he said, his cheeks reddening slightly.

"And I bet your...your, what did you call it back then? Oh, yeah, your peter...I bet your peter has grown a little, too," she smiled, glancing down at the obvious lump in his pajamas.

What? This is too easy, he told himself. She had joked about her breasts, and now she was telling him that she bet his cock had grown since then. Maybe he ought to show it to her. Show her how much it had grown. What would she think? She had thought that five inches was big, back then. What would she think of the eight inch slab of rock hard meat?

"A little," he grinned. "Too bad Mom broke it up..."

"Yeah," she said, sipping on her wine. "I've always wondered what would have happened, if we'd had another ten or fifteen minutes undisturbed. You know that I was a virgin back then, don't you?"

"That's what you said," he snickered, "but I really didn't believe you. You were so grown up and all, and I was just a bumbling kid. I just thought you were saying that so that I would think you were still a virgin."

"Well, I was," she laughed. "See how close you came to getting your first cherry? Your sister's cherry?"

"Damn," he cursed, smiling, "that would have been something. Getting my sexy, hot sister's cherry! Just thinking about it makes, uh, makes... well, let's say it's just as exciting today as it was back then."

"Yeah," she said, taking another sip of wine. "I can see..."

After refilling his glass, he leaned back and laid his arm on the back of the couch. Now their hands were almost touching. Moving his hand closer, he brushed his fingertips over the back of her hand. As he did, he saw her flinch, pulling her hand away, then looked into his eyes. He didn't move as he gazed into her eyes. Then, to his amazement, she eased her hand back over to his, running her fingertips over the back of his hand.

A fiery jolt of excitement arced through his cock, making it twitch down inside his pajamas. She seemed to notice too, as she glanced down at the bulge of his cock, then back up to his face. As they lovingly stared into each other's eyes, Sean gently took hold of her hand and eased it over onto its back. Then, he delicately ran a fingertip over the soft warmness of her palm. Slowly, he rubbed his finger back and forth across her palm as she gazed into his eyes. Finally, he felt her hand ease out from under his. Looking down at it, he watched it grasp his hand and roll it over. Then he saw -- and felt -- her fingernail tickle across his palm, sending another jolt of electricity arcing through his peter.

The signal couldn't have been more obvious.

"Cynthia..." he murmured, leaning toward her and reaching down to the knotted belt of her bathrobe.

Slowly, gently, almost fearfully, he pulled the knot open as they both looked down at his hands.
With trembling fingers, he spread the ends of the belt apart. Then, with the unraveled belt lying in her lap, he clasped the edges of her robe between his fingers. Looking back up into her warm, hazel eyes, he lightly spread her robe open, letting her mountainous treasures slowly appear once again.

"So beautiful," he softly groaned, feasting his eyes on her full, milk-laden breasts.

He continued to spread her robe open until she shrugged her shoulders and it went slithering down behind her back. As it did, he glanced down to see her pussy come into view.

"Oh, God..." he gasped, seeing that her pussy was clean-shaven...bald...bald as Lisa's little butt. "So...so pretty."

Shrugging her shoulders again, Cynthia let the robe fall away from her body to puddle on the couch behind her. She had been sitting with her legs bent at the knees, curled up under her, but as Sean stared down at her pussy, she unfurled her legs. Easing one leg down behind him, she dropped a foot to the floor and spread her legs apart.

"Does it still look the same," she asked, a coy smile playing on her lips. "I shaved for you, so you'd be able to see all the nooks and crannies..."

"You knew? You knew we would...we would do this?" he groaned, realizing that his sister had planned all this.

"Yes...at least I hoped we would!"

"God, it's beautiful," he sighed, reaching down and running his fingertips over the soft, resilient smoothness of her fleshy pussy-lips. "It's so...so sexy now. Back then, it, it was just like a slit...you hardly had any pussy-lips at all. Now they're big and...and fat. They just look so sexy."

"And these?" she smiled, cupping her giant breasts and lifting them.

"They couldn't be any prettier," he groaned, raising his hand and gently caressing the taut skin of her breasts. "They look so heavy...and full, full of milk."

"They are," she laughed softly, making them jiggle and quiver. "Would you like to have a taste of my mother's milk?"

"Sister's milk," he corrected her, leaning toward her. "My sister's sweet milk..."

"Wait! Wait a moment," she said, slipping her leg out from behind him and standing up.

"What? What?" he asked gorging himself on her beautiful, naked body.

"The couch...open the couch," she told him, reaching down and taking his hands.

Pulling him up, she reached back down and flipped a switch and the couch purred, unfolding itself into an already made bed.

"Now," she smiled, crawling up onto it.

As Sean watched on in an euphoric daze, she rolled over onto her back and lay smiling up at him.

"But first," she laughed, running her hand down to her pussy, "I want to see him...I want to see your...your peter. I want to see my brother's big peter."

"Uh, okay," he grinned, reaching down and unsnapping his pajama bottom.

Shyly, he let go of pajamas and felt them go slithering down his legs as his sister, gawked up at his jutting prick.

"My...my...it has grown," she exclaimed as her widened eyes studied the bobbing monster. "I can't believe I thought five inches was big. And look at it now. It's definitely bigger than Billy Johnson's...and Tom's, too."

"Really?" he proudly asked, unbuttoning his pajama top and stepping out of his bottom.

"Really...lots bigger," she giggled. "My little brother's not so little, any more!"

Dreamily, he climbed up on the couch as she reached up and pulled him to her. Her big, puffy nipples were darker now that she had matured, as they glistened with leaking milk. Lying down beside her, he felt her cup the back of the head, gently guiding his lips down to her bulging nipple. Opening his mouth like a baby about to suckle, he took the nipple between his lips and instinctively began to gently suck on it. Her milk began to flow immediately. Tasting the sweet juice as it gushed out into his mouth, he reached under the heavy udder and cupped it in the palm of his hand. It was heavy...heavy with her milk... mother's milk...sister's milk. Initially, he was surprised at the gush of milk that suddenly filled his mouth. With nothing to compare it to except cow milk, he found her milk to be thinner and sweeter.

Savoring the sweetness of her warm milk, he began to suck harder. As he did, he felt some of the nectar drip down his cheek and dribble down onto the couch. Swallowing faster, he felt more of the sweet juice gush out into his sucking mouth. At first he had closed his eyes as he sucked on the big, rubbery bulb, but he slowly opened them and found himself looking at her other tit. Squashed down onto her chest by its heavy weight, its big, swollen nipple defiantly jutted up into the air. As it did, a small, white stream of her delicious milk oozed out of it, trickling down the curved underside of her breast, then disappeared into the crack form between her breast and her chest.

Milk continued to pour forth from her breast as he sucked harder, tasting and drinking down the sweet milk. Strangely, as he sucked, he could feel the tautness of her breast lessen as if it were shrinking while he sucked its delicious contents into his mouth.

Cynthia lovingly ran her fingers through his hair as he greedily consumed her rich, addictive liquor. As she did, out of the corner of his eye, he could see her legs slowly parting while she continued to touch herself, the tip of her long finger caressing her jutting clit.

As she held his mouth pressed against her quivering breast with one hand, she brought pleasure to herself with the other. Then, Sean lifted his hand up to her belly and eased it down between her legs. Running his fingers over the soft, dew-covered lips of her pussy, he pushed her hand out of the way and searched for opening to her femininity.

"Let me do that for you, Cyn," he murmured.

"Oh, yes, please!" she moaned.

Her legs instinctively parted wider as he finally found the warm wetness of her pussy with his finger. Easing his finger down into the moist, clinging tightness of his sister's hot slit, he felt a jolt of electricity surge through his cock as he held it shoved up against her thigh.
"mmmmmmm," she murmured out and began to ever so gently thrust herself up against his hand as he slowly worked his finger in and out of her pussy.
He couldn't believe how easily this had all happened. It was as if it had all been foreordained. They had almost fallen into each other's arms. It was like they had both known it would happen. Tonight, they would finish what they had started those many years ago. Or would it really be a finish? Or a renewal? They would finally consummate the incestuous experiment they'd begun in their father's tool shed.

As he sucked, he could feel the gush of milk slow to a trickle, then stop altogether. He had sucked her big tit empty. He had emptied the beautiful vessel of its creamy filling, and now it was his turn to return the favor. Now he would give up his creamy, seed-laden filling to her.

"Now...now," she whispered.

Reluctant to release her breast, on the one hand, yet excited, on the other, he lifted his lips up off her puffy nipple as a few final drops of milk oozed out of the tip of the purpled nipple. Grunting, he pushed himself up to his hands and knees beside her. As she looked up at him with lust-glazed eyes, he eased one leg over between her legs and then the other. When he did, she spread her legs wider, opening herself to him completely. Staring down at the beauty that lay spread out below him, he felt another quiver of excitement tickle through his big, bobbing cock.

"Yesss," she softly hissed as he lowered his hips, guiding his cock down to the waiting core of her womanhood. "God, yes! Finish it! Finish what we started, so long ago.

"I need to taste your other sweet nectar, first," he told her, and slipped his mouth down along the curve of her body to lap at her dripping sex.

She allowed it, but only for a moment. Her need to be filled by him seemed to outweigh her desire to be pleasured by his lips and tongue.

"You can eat my pussy later, big little brother," she panted, pulling him back up her body. "I want you inside me, now!"

He felt the rounded tip of his cock-head brush against the fleshy lips guarding her oozing womanhood. Then, he felt her fingertips push his cock down, guiding it down into the waiting wetness below. Easing forward, he pushed his cock down into her and felt her hot pussy wrap itself around it.

"Cynthia," he breathed out, easing his cock down into the clutching cavern of her pussy.

Using her feet, Cynthia thrust herself up against him as she wrapped her arms around his neck and pulled his mouth down onto hers. Mouths open, they kissed, their tongues sinuating and intertwining. Sean could feel her pussy clutching down around his cock as they devoured each other.

"Fuck," he finally grunted, tearing his mouth away from hers.

"Yes, baby," she nodded, a wicked smile on her lips. "Fuck me. Fuck your big sister!"

Then he began to work his hips back and forth, pumping his cock in and out of her hungry cunt. As he did, she met him on every down stroke with an up stroke of her own.

As his chest rubbed back and forth across her mountainous tits, he could feel her warm milk coating one side of his chest. It was the tit on the other side from the one that he had just sucked dry. Looking down between them, he could see his chest and her wriggling tit were covered with a sheen of sticky, white foam as his cock plowed in and out of his sister's hot, clutching pussy.
"Seanny….Seanny...Seanny," she murmured out, humping herself back up at him.
Then he felt her lift her legs and wrap them around his back, lifting herself to meet his thrusts.

"Oh, Honey, you fill me like no one has ever filled me," she murmured.

"Good," he grunted, lowering his face down to her undulating tits.

Sucking on her hard nipples, he nipped them with his teeth as she moaned and thrust herself up at his pounding attack. Sucking on her nipple, he found his mouth once again full of the sweet nectar that flowed from her.

"No...No, Baby...Lisa's..." she grimaced.

Understanding that she had to save the elixir from that tit, he unwillingly lifted his lips from it.

Sean hammered his cock into her slavering pussy over and over, feeling emotions he had never felt before. He loved his sister, and the passion of their fucking was quickly fueling a cataclysmic eruption.

"Cyn...Cyn...Cyn...gonna...gonna," he panted, ruthlessly working his hips back and forth, driving his cock in and out of her at a furious pace.

"Me, too...me too...me too...do it...do it," she gasped, working her pussy up against his pistoning prick.

Then, digging her fingernails down into his ass, she let out a long, agonizing grunt as she pulled him down into her pussy.

"Godddd," she gasped, thrusting herself up against him.

Holding him imprisoned in her hot, clutching pussy, she began to shiver and quake. Sean was on the brink of a massive explosion, but held it back as his sister came on his cock. He could feel her hot juices pouring out around the shaft of his buried prick as she came and came. Finally, with a last grunting gasp, she began to melt back down onto the bed as he began to pump his cock in and out of her oozing pussy once again. But this time, knowing she had already finished, it only took a few strokes to bring him the relief he so needed.

"Ohgodd," he groaned out as spurts of hot gooey cum shot from his peter, filling her pussy with its sticky heat. "Cyn...Cyn...Cyn...I love you!"

"Ohyesssss, Seanmy, I love you, too. So much," she groaned, hugging him to her and finding his lips with hers.

They kissed, long and passionately, until his peter was finally empty and her insatiable pussy was overflowing with his potent essence.

"I've wanted this so bad...so bad for so long," she murmured, when they finally broke for air.

"I never knew," he gasped, trying to catch his breath. "Why didn't you tell me...you knew how I felt toward you."

"I couldn't, I couldn't let myself be that selfish. Not even tonight, until I was sure that you felt toward me the way I felt toward you," she told him, clutching her pussy down around his shrinking penis. "It would have ruined everything. If I had, then you and I would have to live out a lie. Live a secret life, never being able to share our secret with anyone. But now...now we can make it work. I have a husband and daughter to hide behind. Now no one will think anything about my hunky brother hanging out here some of the time. No one will ever need to know about our secret."

"But I want more," he complained. "I want you for myself. I don't want to share you with anyone."

"I know. I know. I feel the same way," she wept, "but it can never be like that. That's just a fairy tale. This is the best we can ever hope to have. We'll just have to take every opportunity we have to be together...alone."

"I'll be aching inside every moment we're not together," he whimpered.

"Me, too," she said, wiping the tears from her cheek. "But it will make every second we spend together that much more precious, each moment a treasure that we can take out and savor any time we want, and no one will know...no one but you and me."

"I still think it would be better if we were together all the time," he fussed, slowly easing his deflating prick out of her cum-filled pussy.

"Please, don't ruin it, Sean," she said, gently cupping her milk laded breast. "Come, drink from my well-spring."

"But, Lisa," he muttered.

"I'll give her a bottle..." she said, smiling at him.

Crawling up beside her, he laid down. As he lowered his mouth down to the big, pouting nipple, pointing up at him, she cradled his head in the crook of her arm. Closing his lips around the purplish-pink knob, he began to suck, gently at first, but harder as he felt the warm nectar begin to flow into his mouth.
He stopped his sucking for a moment, gently running the tip of his tongue around her big, darkened nipple. Then, he sucked the bloated nipple back into his mouth and flicked his tongue back and forth across it as she looked down at him lovingly. Beginning to suck again, he was rewarded with another gush of warm, sweet milk.

Cynthia lay on the bed with her head thrown back, her eyes closed, her lips partly open as Sean continued to pull on the nipple with his lips. Her breathing rate increased, making her breast rise and fall at a faster pace as he sucked and teased her big, rubbery nipple. Running his hand down over her jiggling tummy, he searched for the opening of her pussy. As she felt him running his finger up the juice-coated rift between her fleshy love-lips, she eased her legs wider apart, opening herself for him. Finding the slippery entrance to her pussy, he slowly eased a finger inside. Running his fingertip along the top of the channel of her vagina, he searched for and found her ridged g-spot.

"Oh, I feel like I have to pee," she complained.

But as he began to slowly press against the spot with deep, steady strokes of his finger, she began to gently hump herself up at his hand.

Lifting his mouth from her breast, he saw that she had her head back and her eyes closed.

"Touch yourself," he whispered, working his finger across her g-spot.

"Ummmmmm," she murmured, running her hand down to her over her tummy to her clit. "So good...feels so good."

"Um-huh," he mumbled out, lowering his mouth back down to the oozing nipple and sucking it back into his mouth.

Her milk...her sweet, warm milk began to flow again as he tenderly pulled at the pliant knot of quivering flesh with his lips. He couldn't get enough of the sugary cream flowing from her beautiful breast.

"Oh, Seanmy," she gurgled, pressing her pussy up against him harder as she flicked her fingertip back and forth across her jutting clit.

He could feel a frothy coating of her milk covering his lips as he sucked on her compliant breast and nipple. Then, crazily, a picture of a guy with a milk mustache popped into his head from the commercial.

Got Milk. he giddily asked himself?

Suddenly, her breast began to jiggle and shake as her beautiful butt jerked and shook.

"Unh...unh...unh," she grunted out in a long groaning whine as she pressed herself up against his hand.

Her hand flew away from her clit and she grabbed up a fist full of the sheet while she made a grimacing face.

Then all at once, he saw a spurt of juice shoot up from her pussy into the air and splash down onto her heaving belly. Wondering what had happened, he knew that the gush of juice hadn't come from her vagina because his finger was still shoved up inside it, and that left only one other place...her urethra. Was she peeing, he dizzily wondered as a second gush of glistening stuff spurted up, this time landing on his hand and coating it with its sticky warmness. It wasn't pee, he drunkenly thought. It was too thick to be pee. It was juice...pussy juice...or something like it, he told himself, easing his finger out and rubbing some of the stuff between his finger and thumb. His sister was coming...coming and spurting out something that was a lot like cum. This was all just too damned amazing. He had never heard of anything so...so fucking crazy.
Finally, her hips dropped to the bed and she gave out one last shuddering groan. It was difficult keeping his mouth latched down around her spewing nipple with her breast heaving up and down as she tried to catch her breath.

"God, Seanmy..." she wheezed, "it never felt like that before. It...it was the best ever..."

Lifting his milk-slathered lips up from her breast, he looked down on her and smiled.

"I never saw a woman do that before," he grunted, staring down at her glistening belly.

"I've never done it before," she muttered, running her fingertips through the gooey mess covering her belly. "I didn't know that a woman could come like that. But I guess I did."

"You sure did," he laughed.

Lifting her juice-coated fingers to her mouth, she tentatively licked her tongue across them. A smile lit up her face as she dipped her fingers back down into the goo and brought her fingers up to his froth-covered lips.

"It even tastes a little like cum," she said as Seanmy ran his tongue across her fingertips.

"Unh-huh," he mumbled, looking down at the whitish froth covering her areola, surrounding the big, purplish nipple poking up out of the center of it, "but your milk is sweeter.

"I guess that's why men like it so much," she laughed softly, cupping her other breast and slowly lifting its nipple up to her mouth.

Seanmy watched on in fascination as she bent down and sucked the big, bulging nipple into her mouth. Watching her suckle herself put the finishing touches on his erection as his cock jutted out hard and ripe once again. Slowly lowering her tit back down to her chest, she looked down and saw that his cock was hard again.

"Would you like to fuck them," she asked.

"What?" he muttered, unsure of her intent.

"My tits...would you like to fuck my tits?" she smiled, cupping them in the palms of her hands.

"Yeah...yeah, I'd like to fuck your tits," he grinned, pushing himself up to his hands and knees.

Easing a leg across her, he straddled her goo-covered belly and slowly inched forward until his big, bloated cock was above the valley between her huge breasts. As he did, he felt his big, dangling balls drag through the goo, coating them with a slippery sheen of her essence. Looking down at her smiling face, he lowered his cock down until it touched her hot skin. With his knees splayed out in line with her tits, he watched her clutch her tits and squeeze them down around his cock. Holding his cock trapped between her tits, she grasped her nipples between her fingers and thumbs. Then as she toyed with her nipples, Sean saw them begin to dribble out two streams of white milk down onto his cock. The milk provided lubrication for his cock as he began to slowly work it back and forth between her tits. Fucking her monster tits was euphoric in itself, but doing it while his cock was being bathed in her sweet milk was pure ecstasy.

"Cynthia...this is so fucking hot," he muttered out, leaning down over her, resting his weight on his hands and knees as he watched his big, milk-slathered cock sliding in and out between her big tits.

"Wait," she panted, throwing an arm out and grabbing one of the pillows.

She shoved the pillow under her head, bending her head forward and placing her lips right in the path of his thrusting cock-head.

"Oh fuck," he cursed, as he began to rock back and forth again, watching and feeling the head of his cock slide between her lips every time he thrust forward.

In no time, his peter had churned up a milky lather between her breasts as it sloshed in and out between them.

"Milk shake," he snickered, looking back down between her breasts. "We're making a milk shake..."

"Um-humkk," she muttered, just as his cock-head popped back into her mouth.

Sean could feel the fireball down inside his flopping balls begin to gather and form into an impending explosion. As it grew, he worked his hips back and forth faster and faster, making his cock pop in and out of her sucking mouth.

Then at last it came as his dick jerked and spewed out a mammoth gusher of creamy cum onto her pretty face, coating her lips and nose with its sticky heat.

Before he could release another load, Cynthia jerked her hands away from her tits and dug her fingernails into his ass, pulling him forward. His peter slid between her lips, into her mouth and continued, bumping against the opening of her throat just as the second giant load spurted out of the tip of his prick.

Coughing out a little gag, she dug her sharp claws in deeper, pulling him forward until he felt the head of his cock pop into her throat just as it spewed out the third thick gob of cum directly into her throat.

"God! god! god!" he gasped out as his peter erupted a fourth and fifth time before it began to die down inside her hot, sucking mouth.

He was dead from the waist down. He could barely even stand on his hands and knees as his trembling legs turned to rubber.

Pulling back, he eased his dick out of her throat and then her mouth. Rolling over, he flopped down on his back beside her. Trying to catch his breath, he looked over at her and saw her run her little pink tongue over her lips as she smiled at him. Then she wiped the back of her hand across her lips and chin, wiping away the creamy coating that covered them.

"Was it good for you?" she asked, reaching down and fingering his limp prick.

"What do you think?" he groaned, leaning over and giving her big, jutting nipple a kiss.

"I think so," she laughed softly, leaning over and giving him a long, lingering kiss on the lips. "I think so..."
