After Bill and Stacy left for the beach, Karen found a book to read and lay down on the couch. She knew she ought to check on Mark now and then to see if he was cleaning the basement, but she was afraid to be alone with him. He would probably make another pass at her, and she wanted to avoid the hassle.
The hours dragged, and she found it hard to concentrate on her book. She knew what the problem was, dammit – she was horny again. That was nothing new, of course. She seemed to be horny all the time. The question was, what to do about it?
"Oh, hell," Karen sighed.
There seemed no way out of her predicament. Her husband was bored with her in bed and had practically stopped fucking her. She wouldn't dream of being unfaithful to him. All she could do was maturbate, like a guilty little kid.
She knew she'd have to bring herself off soon, or she'd grow irritable and be snapping at everybody all evening. She just had to make sure that Mark was busy in the basement and wouldn't interrupt her. It would be awful if he caught her frigging herself.
Karen slipped off her shoes and crept quietly to the basement door. It was slightly ajar, and she peered through the crack. Mark was busy, all tight, loading junk into cartons. He still had a big pile of stuff to load, so he ought to be busy for a while longer. Reassured about her privacy, Karen tiptoed back to the living room and lay down on the couch.
Sighing, she slipped her hand down the front of her stretch pants and touched the springy puff of curls at the base of her belly. She wriggled a finger inside the furry lips and found the hot little lump of her clit. A jolt of pleasure rocked her body as she pressed down on the sensitive juicy little button.
"Ummm," she sighed.
She began to stroke her clit gently but insistently, and her starved cunt responded with a steady trickled of juice. She sighed and spread her legs a little. It felt so nice… A cock would have been better, of course, but none was available. She had to do the best she could with her own hand.
Beginning to breathe harder, Karen slipped her stiff wet finger farther down between her thighs and rimmed the wet mouth of her famished cunt. Fantasies began to come to her, fantasies of Mark climbing over her, sticking his superb, stiff young cock into her… She creamed hard, soaking her finger.
"Ummm, yesssss," she whined.
She began easing her finger into her flaming wet box, pretending that her handsome young nephew was penetrating her, slowly and teasingly slipping his rigid fat young prick into her. She moaned softly.
"Yes, darling, yes," she sighed.
Mark had been sitting on the old mattress in the basement, smoking a cigarette, when he heard the floor creaking above him. Quickly he snuffed out the cigarette, leaped to his feet, and began carrying junk to the carton Karen had provided. He certainly didn't intend to break his ass on this job, but he had to keep up appearances.
Out of the corner of his eye he saw Karen peeking at him from the top of the stairs. She looked for just a moment, then crept away without saying a word.
That puzzled and irritated him. If she was going to keep checking on him, dammit, she could at least say hello. Mark's temper was in bad shape today anyhow. He was horny, and he ached to get it on with his beautiful adoptive mother, but he hadn't figured out a good approach yet.
Well, to hell with approaches. He was just going to go right upstairs and have her, rape her if he had to. Stacy and Bill were at the beach and would be gone for hours – he could trust his sister on that score. There'd be plenty of time for his conquest of Karen.
Mark started up the stairs, flushed and determined, but something told him to proceed quietly, not give her any warning. Karen had spied on him, obviously not wanting him to see her. Maybe she was doing something she didn't want him to know about.
He reached the top of the stairs and opened the door without a sound. He stood there listening, and from the living room he heard peculiar noises – sighing, soft moaning, little whimpers. What the hell…?
Mark crept toward the open archway of the living room, hardly daring to breathe. He knew something funny was going on, and he wanted to find out without Karen noticing him. Maybe she had a guilty secret, something he could use against her.
When Mark peered around the corner of the archway, he discovered his hunch was right. She had a guilty secret, all right, and it was a beauty. His aunt lay on her back on the couch, her hand thrust down the front of her pants and moving swiftly, rhythmically. She was panting and whimpering.
Mark grinned wickedly. His cool aloof aunt was frigging herself.
He waited a moment, planning just what he would do. He had her now, of course. He could use her secret to make her do whatever he wanted. But he wanted to get maximum pleasure out of it, and that required some thinking.
Meanwhile Karen was really getting into it. Impatient with the restriction of her tight pants, she tugged then down to her knees. She then pushed her panties down, too, exposing her pretty fluff of golden muff fur. That was better. With a sigh she again slipped her hand into her crotch.
Mark watched, grinning broadly. He saw his lovely but aloof aunt slip a finger into her wet hair-fringed cunt mouth. She pushed the finger into herself all the way to the last knuckle, and her lovely face contorted into a lusty snarl.
"Oooo, yesss," she whined, "yessss…"
As Mark watched raptly, she began to pump her finger in her juicy little cunt, working it in an out swiftly like a cock. Her white teeth flashed in a lusty grin, and her moans grew husky and prolonged. The poor chick was really starved for sex.
Well, she wouldn't have to wait much longer. Mark intended to give her the real thing.
He crept silently into the living room. Karen's eyes were tightly shut now as she abandoned herself to her own erotic fantasies, whatever they were. Her finger, soaked and gleaming with her plentiful cream, moved faster and faster in her aroused cunt.
"Oh, my God, yes, darling," she whimpered. "Fuck me, Mark…"
Mark almost howled in triumph. She was pretending it was him. Too fucking much! The bitch had turned him down, refused to ball him, but in secret she wanted him desperately. He couldn't pass up an opening like that.
"You called me?" he said distinctly.
Karen froze. She prayed her ears had deceived her, but as she opened her eyes she saw her nephew standing right beside the couch, leering at her. He'd seen everything, heard her calling his name. He'd caught her in that shameful act, her pants down around her knees, her finger stuck in her cunt. Oh, God, it was too awful!
"Oh, NO," Karen gasped, bursting into tears.
She slipped her cream-soaked finger from her cunt and started to pull up her panties, but Mark seized her hands and held them. He sat down on the edge of the couch and looked at her, his blue eyes hot and lusty and amused.
"Hey," he said, "no need to cry. You want me, Auntie, you can have me. You can have the real thing. Shit, you should've told me before. I would've been glad to take care of you."
Karen moaned and shook her head. "You don't understand," she sobbed. "I'm so ashamed. That you should see me doing a thing like that…"
"Oh, hell, that's nothing," said Mark. "Everybody does it. But you don't have to any more, see? I'll fuck you anytime you want it."
Karen shuddered. She knew he wasn't kidding. He'd fuck her, all right, make love to his own aunt under Bill's nose. It was a sickening situation. The boy had the morals of an alley cat.
"That's out of the question, Mark," she said coldly. "I won't cheat on my husband, and I wouldn't dream of doing it with my adopted son. Please, forget it."
Mark sighed deeply. "Wow, you are really something else," he said with exasperation. "You'll frig yourself and pretend it's me. You'll suck my cock and eat my come. But you won't ball me. That's crazy, Karen. It's buflshit. You're being ridiculous. We want each other, so why shouldn't we do it?"
He was right – she was being a terrible hypocrite. But her conscience still told her it would be wrong to fuck this boy, her blood nephew.
"Mark," she said shakily, "I know I'm not being logical, but I just can't bring myself to do it. Now, please, let go of me. That answer is no, and that's final."
He gripped her wrists even harder. "Oh, no, Auntie," he said harshly, "the answer is yes and I won't quit till I get into you. Make it easy on yourself and just spread those legs. I'm gonna get to you sooner or later."
"No," Karen sobbed, "never…"
Mark was tired or arguing. He leaped up and straddled her, his tight muscular ass resting on her big heaving tits, his crotch almost in her face. Holding her flailing hands aside with one fist, he quickly unzipped his fly and took out his pale limp prick. He let the doughy warm rod fall on her trembling lips.
"Okay," he said. "You don't wanta fuck me, you can blow me. Come on, open up. Suck me off like you did yesterday."
Karen quickly obeyed. This would buy her some time, and she wouldn't have to fuck him today. She opened her lips and let the soft warm meat drop into her mouth. She sucked him in strongly taking his limp cock all the way to his balls.
"Yeah, that's good," Mark sighed. "Suck my dick, Auntie…"
He was lying, of course. He didn't intend to let her off so easily. This time he meant to ball her, no matter how she fought or how much she protested. He was tired of her bullshit. He was so horny he could have screamed. He'd let her suck him, get him hard, and then she was in for a surprise.
Karen's hot juicy mouth felt really good around his sensitive prick. She sucked fast and greedily, obviously hoping to bring him off fast and be done with it. Mark abandoned himself to the keen pleasure of having his meat sucked, and it wasn't long before he began to grow hard.
"Yeah, yeah," he sighed, "blow me, baby… Suck that meat… Yeah, that's great…"
Karen sucked him even faster and harder as she felt his strong young boy-cock growing hard in her mouth. It shouldn't be too much longer now before he came. His meat grew thick and hard, stretching her lips painfully, and his cock-head swelled up hugely, butting her throat. She almost gagged, but she kept on sucking.
Mark waited till he had a good solid hard-on before pulling his spit-soaked rod from her mouth. He grinned evilly at her when her eyes widened with surprise.
"But, Mark," she said, "I haven't finished. Don't you want me to bring you off?"
"Sure, baby," he said, "but not that way. I'm dying to test that cunt of yours."
He began to slide down her trembling body, taking care not to let her roll away. Her pants were down to her knees, her pretty blonde muff exposed. He had a clear shot.
"Mark, NO," Karen wailed. "I told you, I don't want to do that."
"And I told you I do," he snapped. "Now just shut up and take it, Auntie, because you're gonna get it whether you like it or not."
Karen fought desperately, but he pinned her wrists down to her sides, and the weight of his body prevented her from rolling away. It would do no good to scream for help. Her husband was miles away at the beach.
"Oh, no, no," she sobbed. "It's wrong, Mark, can't you see that? I'm your Mother!"
Mark paid no attention. He moved down till he straddled her thighs, and then he poked the fat creaming head of his dick between her tightly clenched legs. She screamed and locked her legs together, but she couldn't keep him out. He grunted and pushed till he felt his drooling cock-head slipping into the slick mouth of her cunt.
"Now," he panted, "now I'm gonna get into you, Auntie, and there's nothing you can do about it."
He slammed his hips forward with brutal force, and Karen felt his thick, hard, adolescent prick ripping into her tightly clenched twat. She couldn't keep him out. He plunged all the way in, till she felt him butting her womb.
Mark sighed and let himself down on her. "I'm in now, Auntie," he said triumphantly. "I'm gonna ball you real good. Why don't you just relax and enjoy it?"
Karen sobbed in protest, but as his rigid young cock began to move inside her, dizzying waves of pleasure racked her body. She'd been without a man so long, she'd been so achingly horny, that it was impossible not to enjoy it.
Mark fucked her in hard deep strokes, completely stuffing and filling her starved box with each swift plunge. It was so different from Bill's languid half-hearted fucking. It was the almost brutal rape-like fucking she'd craved for years. Helplessly she began to cream around his deep-thrusting cock.
Mark felt it. He felt her cunt juice boiling around his dick, felt her clinging twat growing hotter by the second. Soon she began to move her hips helplessly, and her breathing got fast and loud. She had a fine cunt, tight and fiery and slick. He was enjoying himself hugely, and he sensed that she was, too, only she wouldn't admit it.
"Good, ain't it, Auntie?" he panted. "You really needed this, didn't you?"
Karen's face flamed. "Nooo," she whined. "No, no, please, take it out of me."
Mark chuckled. "Still giving me the old bullshit, huh? Well, I don't buy it, baby. I can feel you creaming all over me. You dig it, I can tell. You were hot for me."
Karen could have died of shame. Her lust was so obvious, she couldn't even fool a eighteen-year-old boy. He had her number, knew she'd been wanting him. She turned her face to the side and sobbed, hating herself.
"Hey, no crying," Mark said. "That's dumb, Auntie, really dumb. I mean, I'm balling you, right? And there's no way you can stop it. So why don't you relax and dig it? Why cheat yourself?"
Something snapped in her mind. He was right, dammit, perfectly right. She'd done all she could to prevent this incestuous act, but now it was happening, and she might as well enjoy it. Hell, she'd been wanting a lover like this for years.
She relaxed. Mark could feel it. The stiffness went out of her body, and her cunt opened up to his jerking meat. He felt a fiery flood of cream bathing his dick. She reached up and clapped her hands tightly around his ass, pulling him into her. She began to move her wet, hot pussy in time to his strokes.
"Yeah, yeah, baby, that's it," he said excitedly. "Be up front about it, dig it. You know it's good."
He began to fuck her faster and harder, and Karen almost screeched with pleasure. His hard energetic young cock felt marvelous in her long-starved cunt. She dug her nails into his muscular ass, urging him deep into her.
"Ahhhh," she moaned, "ahhhh…"
"Tell me about it," Mark whispered, "tell me you like it… Come on, Auntie, no holding back now…"
His victory wouldn't be complete until she told him how much she liked it. He had to conquer his women completely. He rammed his cock deep into her, giving her the fierce friction she craved. He felt her cream flooding helplessly around his jerking meat.
"Oh, God," Karen whined, "yes, yesss…"
"You like it?" Mark persisted. "Tell me."
"Yes," she gasped, "yes, I love it…"
She felt a brief moment of shame, but it was drowned in the stunning pleasure that rocked her body. To hell with everything else, she needed this hard prolonged fucking. She could worry later, feel guilty later. Right now she wanted to lose herself in joy.
"It's wonderful, Mark," she babbled. "Soooo good… Please, keep fucking me, keep doing it to me…"
Mark grinned broadly. "You bet I will," he panted. "I'm gonna fuck you raw, baby…"
That was a slight exaggeration, but he did bring her off several times before coming himself. He delighted in watching his beautiful stepmother come, in watching the way her normally cool face twisted in a sensual leer, the way her lush body rocked in climax, the way she moaned her bliss. He had mastered her completely with his cock.
Karen knew she was mastered, and she loved it.
She forgot everything else, opened her famished cunt to him, and came joyfully again and again. Finally Mark gave a blissful yelp and pumped his jism into her. Shyly Karen let him rest on her body while he caught his breath.
"Oh, man," he sighed, "far out… Just let me rest a second… Let me keep my cock in you. I'll get hard again real soon, and we'll do it again."
Karen opened her mouth to protest, then wondered why she bothered. The damage was done. She'd fucked her own eighteen-year-old nephew, and she'd loved it. He knew she'd loved it. She couldn't sink any lower than that. Doing it one more time wouldn't change things.
Besides, she wanted it. She'd been waiting years to be fucked like this. As she felt Mark's insatiable young cock growing hard in her again, she creamed eagerly. He jammed his mouth onto hers, worming his tongue inside, and she responded with her tongue, weaving it around his in a lewd dance.
"You ready to do it again?" he said.
"Yes," Karen whispered.
Just then they heard a car coming into the driveway.
"Oh, my God, it must be Bill and Stacy," Karen yelped. "Quick, Mark, get off me."
They leaped apart, and Mark somehow managed to stuff his hugely erect cock into his jeans. He clattered down the stairs to the basement. Karen pulled up her pants and patted her hair into place, blushing hotly.
Bill's arrival had at least restored her to her senses. She'd done a terrible thing, balling her own young nephew. She'd never do it again, she swore.
When Bill came into the house, she greeted him cheerfully but couldn't meet his eyes.
She didn't notice, but he couldn't meet hers, either…
Late that night after Bill and Karen had gone to bed, Stacy sneaked into her brother's room. They hadn't been alone together all day, hadn't had a chance to compare notes. She was bubbling over with the news she had to tell Mark. And she knew he was waiting impatiently to tell her about his own adventures.
Mark was lying on his bed, wearing only his jockey shorts, waiting for Stacy to come. He knew she'd be there, as soon as she was sure the adults were asleep. Finally the door opened quietly, and Stacy came bouncing in, wearing a short nightgown that hardly covered her ass.
She ran over to him and bounced onto the bed, giving him a quick hug. "Oh, Mark," she exclaimed, "I can hardly wait to tell you about my day."
"Okay, okay," he laughed, "but keep it down. We don't want to wake them up. So what happened at the beach? Did you get it on with Uncle Bill?"
Stacy nodded gleefully. "I finally did it," she said. "It wasn't easy. Man, he was protesting right up to the last second, even when I sucked his cock, but he finally gave in. I've got him now."
"Far out," said Mark. "And I've got good news, too. I finally got into Karen. She was just like him, protesting all the way, but when I got my cock into her, she changed her tune. Looks like we've succeeded, little sister. We won't have to sneak out at night to look for fun if we don't want to. We can have it right here."
Stacy clapped her hands. "Oh, Mark, I'm so happy," she said. "But is Karen a good lay?"
"Yeah, she's fantastic," Mark said, sighing at the memory. "And she's gonna get better. She has a lot of inhibitions to lose, but she digs it. What about Bill? Is he any good?"
Stacy sighed, too. "Oh, wow, yeah," she said. "He's got the biggest cock I ever saw. In fact I get horny just thinking about it."
"I'm horny, too," said Mark. "I was gonna make it with Karen a second time, but you guys came home. Listen, you wanta play our game?"
Stacy nodded eagerly. "Yes, that's a good idea, Mark," she said. "I'm really up for it."
Brother and sister quickly took off their clothes.
Mark and Stacy had a special game that had begun a long time ago when they were just children. It started during a brief period when their mother had to work nights, leaving them alone in the apartment. There was plenty of food, the lock was secure, and they were in no danger, but the two kids sometimes felt spooky without their mother.
So Stacy got into the habit of crawling into her brother's bed.
At first it was just for company. The kids felt safe and secure together. Then after a couple of weeks they started exploring each other's body, curious about the difference between boys and girls. They discovered that touching each other, especially between the legs, was a lot of fun.
They refined their play, telling each other what they liked best, and then one memorable night they accidentally made each other climax. It was the first time for both of them. They enjoyed it so much that they made it into a permanent game.
Their mother started working days again and staying home at night, and she said they couldn't sleep together, that they were getting too old for that. So they just waited till she went to sleep. As they grew into adolescence, they invented more and more crazy things to do. But so far they hadn't fucked. In fact, it didn't occur to them. That was something they did with other people. Their own private game consisted of delicious touching, nothing more.
"Move over," Stacy giggled. "You're taking the whole bed."
"Okay, greedy," Mark laughed.
They had pulled the covers down so they could see each other. They loved each other's bodies. Mark thought his sister was the prettiest girl he'd ever seen, and Stacy thought her big brother had a really super body.
They lay down side by side and began touching each other. Mark began by fondling and squeezing his sister's plump round tits, something he knew she liked. Stacy seized her brother's limp little prick and playfully pumped it.
"So ol' Bill's got the biggest dick you ever saw, huh?" Mark said, grinning. "Is it bigger than mine?"
"I'm afraid so big brother," said Stacy, fondly petting his soft sleepy prick. "But you've got some growing to do yet. You might catch up with him."
Mark happily fondled his sister's firm little jugs. "Well, my feelings are hurt," he teased. "I'm just gonna have to tell you that Karen's tits are a lot bigger than yours. Man, they're like mountains."
"I know," Stacy sighed. "I sure hope mine get bigger."
"Aw, I was just kidding, Sis," said Mark. "Yours are fine, the nicest I've ever seen. Anyhow, if they were any bigger, I couldn't get 'em in my mouth, and that'd be a drag."
Stacy giggled, but her eyes were hot and glowing. "Hey, Mark," she said huskily, "why don't you just do that? Suck my tits, I mean. I could really get off on that."
"Okay," said Mark, "but you gotta do something nice for me, too."
"Oh, I will," Stacy said impishly. "You better believe I will."
Mark brought his mouth down to one of his sister's pretty pink nipples and tickled it teasingly with his tongue. Stacy squealed with delight.
"Hey, not so noisy, okay?" Mark said fondly. "The shit would really hit the fan if they found us like this."
Stacy sighed. "Yes, dammit," she said. "Wow, those two are really a drag."
"Not for long," said Mark. "We're working on them. Now I'm going back to working on you… but keep the noise down."
He popped his mouth onto his sister's perky little nipple and began to suck it leisurely. He felt the soft tip of her breast slowly harden in his mouth, getting erect and throbbing. Stacy almost squealed again but managed to convert it to a prolonged sigh of pleasure.
Mark felt his sister's little hot hand closing around his flaccid pink balls. He hummed happily to himself. He really liked it when Stacy played with his nut sacs, because she knew just what to do. He felt hot excitement as she began to knead and massage the soft sensitive bags.
Brother and sister lay side by side, naked, a beautifully matched couple with their deeply tanned trim bodies and thick platinum hair. Mark's head bobbed gently over his sister's ripe round tit, and Stacy's hand moved rhythmically around her brother's fat young balls. A stranger might have thought they were lovers.
But they had never really been lovers, and Mark was just now beginning to wonder why. Somehow in all the years they'd played together in bed, they'd never thought of fucking. They'd done everything else but that. It made Mark chuckle.
"What's so funny?" said Stacy.
Mark drew his mouth off her wet erect nipple. "Aw, I was just thinking," he said. "It seems weird that you and I never ball each other."
Stacy blushed slightly. She wasn't one for blushing, but Mark's thought had occurred to her lately, too. It did seem kind of strange, and yet…
"Well, but Mark, we're brother and sister," she said. "It wouldn't be quite right, would it?"
He stared at her. "You've been listening to that bullshit Bill and Karen put out," he said, "that crap about incest."
"No, I haven't," Stacy protested. "I mean, I don't believe it's necessarily wrong. It just seems kind of funny, that's all. I mean, my own brother…"
"Oh, Christ," Mark said scornfully. "Okay, if it bothers you, let's just forget it."
It did bother Stacy, but she didn't know why. Idly she reversed her position beside Mark so she could lick his balls and he could play with her pussy. It was one of their favorite things. Usually they made each other come that way. But now Stacy was thinking maybe her brother had a point.
Mark eyed the pretty little puff of platinum fur over his sister's muff. It was the loveliest muff he'd ever seen, and he got aroused just looking at it. He quickly parted the blonde furry lips and exposed the tiny red bump df her clit. His tongue snaked out to tickle it.
"Ummm, yeah, Mark," Stacy sighed, "that's good…"
She returned the favor by sticking out her dainty pink tongue to lap and tease his pretty pale cock. She'd seen a lot of cocks in her short life, but she still thought her brother's prick was the most handsome and exciting. She loved to lick and taste it.
"Yeah, Stacy, that's nice," Mark moaned. "Lick my cock, yeah…"
The room was quiet for awhile except for the faint wet lapping and sucking sounds as brother and sister tongued each other. Mark pressed his mouth against Stacy's tasty little clit and sucked on it, making his sister cream hotly into his face. Stacy sucked his cock into her hot juicy little mouth, tugging it greedily, and Mark moaned.
He was thinking how much he'd like to get it on with his pretty little sister. Stacy was right, it did seem kind of strange, but he figured they could overcome that in a hurry. Stacy was the sexiest girl in the world as far as he was concerned, and once the idea had entered his head about fucking her, he couldn't stop thinking of it.
Stacy sucked her brother's cock fast and hungrily, quickly getting him hard. She thought how much she loved her brother's prick and how it might feel inside her. She'd always suspected that Mark was a fantastic lay. So what did it matter if he was her brother? No one had to know…
"Suck me," Mark gasped, "suck me, Stacy, bring me off…"
This was always an exciting moment for him, when his horny little sister started sucking his meat furiously, bringing him to a helpless yelping come, while he sucked on her tiny clit and made her climax all over his face.
But now, to his surprise, Stacy suddenly spat out his erect, swollen dick. She was looking at him with hot glazed eyes, a really weird look.
"Hey, what's happening?" Mark asked.
Stacy's voice was husky. "I changed my mind, Mark," she said. "I want you to ball me."
Mark's full cock twitched with excitement, but he gently kissed his sister and said, "Are you sure? I don't want you to be sorry later."
Stacy ran her small hand lovingly up and down the rigid throbbing pole of his dick. "Yes," she said, "I'm sure. As long as nobody knows, Mark, you and I can do anything we want. We can have our own world."
"That's fight," Mark said enthusiastically, "just like always… our own world that nobody else knows about."
Stacy smiled adoringly at her handsome brother. She let herself fall slowly back onto the bed, her lovely light blonde hair spreading over the pillow. She slowly opened her slim long legs, unveiling her ripe pink pussy, and her eyes dropped hungrily to Mark's rigid young prick which strained against his belly and bubbled bright drops of cream.
Mark stared at his little sister's beautiful pink slit. He'd sucked it often enough, licked and tasted and explored it, but he'd never had his cock there. His breathing grew quick and excited. He crawled over to her and knelt between her silky thighs.
"Yes, Mark, do it," Stacy breathed. "Hurry. Oh, Mark, I'm so excited."
"Me, too," Mark admitted.
Gingerly he bent his stiff swollen rod till the bulbous dark-red tip touched the steamy little pit of her cunt mouth. Stacy moaned hungrily but held still for him, and Mark wedged the fat head of his dick into her. He held it there, just an inch inside her seething little box, savoring the moment. He thought, I'm balling my sister. But the thought didn't repel him. It turned him on.
Stacy was no longer afraid, either. Her tiny teenage cunt seethed with excitement when Mark wedged his big cock-head into her and held it there. The idea that her own brother was about to stick his cock into her was tremendously arousing to her. Her hot cream bubbled around his intruding cock-head.
Mark sighed deeply and let himself down on her, his hard young chest flattening her ripe pointed jugs. His cock glided into her, slowly nosing to her womb, and brother and sister embraced each other tightly and moaned in their excitement.
"Ball me, Mark, ball me," Stacy chanted.
"I will, little sister, I will," he panted.
Stacy felt his fat young prick moving in her and she gave a shrill howl of pleasure.
