Chapter 4

Terri knew there was a change in Karen, but she didn't know why. Her aunt seemed happier. And even now, as she cooked supper —something Terri knew her aunt absolutely hated doing—she was smiling to herself.

Sitting on Mack's bed, Terri wished she could find a man to fuck her. Getting finger-fucked by her brother until she came wasn't bad, but it certainly wasn't like taking a big cock up her wanton pussy until she spewed out

the slick pussyjuice. And nothing could possibly take the place of having a big, tasty cock stretching her lips and pumping delicious jism down her throat.

"It's so damn hot," Terri mumbled under her breath, wishing the log cabin had electricity so they could at least have a small fan. The gas stove and oven were the only modern conveniences in the cabin.

"There's no sense in complaining," Jeff said to his sister. "The heat's here and there's nothing we can do about it."

Karen chirped in, "That's right, Terri. Might as well get used to it and try and make yourself comfortable if you can. Supper will be ready soon and then this damn stove will stop heating this cabin even more."

Terri slipped off her leather jogging shoes and wiggled her toes. It felt better being barefoot. She stretched her arms above her head, causing her melon-like tits to rise higher in her rib cage.

"Ohhhhhhh! What I need is to have a good swim in the creek," Terri murmured.

She was bored and horny. The combined effect of those two stimulants was making Terri feel perfectly willing to do just about anything to relieve either the boredom or her homines s—or best, both.

"Yes, I think that would be fun after supper," Karen said, paying little real attention to her niece.

Terri looked at Mack, rolling her tongue in a suggestive manner around her mouth. Mack returned the smile, but felt uncomfortable with his sister's openness. He still had pangs of guilt for having let his older sister jerk him off.

Terri looked at Jeff and saw that he was gazing at Aunt Karen's profile. Terri thought his expression seemed a bit strange, but she didn't pay it much mind. It was time, she thought, to give her aunt something to choke on.

Leaning back on Mack's bed, Terri unsnapped her jeans. Raising her ass, she wiggled out of the tight-fitting garment. Not one to wear panties, her cuntal bush was exposed to Mack's hungry gaze. The cunt hair, almost straight and growing toward her pink slit, was darker than the honey-colored hair on her head. Terri pushed the pants down her legs, then kicked them off entirely. The jeans landed several feet from her in the middle of the room.

"Ohhhhh!" she sighed contentedly. "That's a little better. It gives my body a chance to breathe."

Both Jeff and Mack had seen their sister naked countless times so her nudity was no stranger to them. At home, her dislike for pants was common knowledge and Terri's parents had long since stopped bothering her whenever she walked around the house in the nude. Occasionally they would ask her to put a

houserobe on, but not very often.

Unbuttoning her shirt, Terri pulled it open and shook her shoulders, sending her perfectly shaped, high-riding tits in motion. The areolas were dark and round, the nipples elongated. She rolled the ultra-sensitive buds between her fingers and thumbs, crooning softly with the pleasure her own touch provided.

"Yes, this is much, much better," Terri sighed, kicking her legs out as she spun on the bed, stretched out with her hands crossed beneath her head. "Now the heat isn't so miserable."

When Karen grabbed the kettle of stew and turned away from the stove, she was caught unprepared for the sight of her lovely, big-titted niece naked on the bed, brazenly showing off her tits and cunt to her brothers.

"Terri! What on earth do you think you're doing?" Karen exclaimed, standing frozen in her tracks. "Put some clothes on! Don't you see your brothers are around?"

Terri shifted lazily on the bed, propping her head up with her chin in her palm. Her firm tits rolled to one side, one resting on the other, her shirt only partially hiding the beauty of her mountainous tits.

"Lighten up, huh? At home I've never got my clothes on." Terri enjoyed the look of total shock on her aunt's face, but did not reveal it with her own expression. "And believe me, Mack and Jeff have seen my body enough

times not to get all hot and bothered. Besides . . . we're all family here, aren't we?"

Karen didn't know what to say. She wasn't sure if her niece was telling the truth, but she suspected Terri was. Karen knew her brother well, and he had always been liberal and open-minded. Letting his sons and daughter walk around the house naked wouldn't be altogether unlike him.

"Well ... I guess if it doesn't bother anyone else . . . then I guess I can get used to it, too," Karen said after much hesitation. She put the stew in the center of the round wooden table, trying not to look at Terri's resilient young tits. "Come on everybody, let's eat."

When supper was over and the dishes had been washed, dried and put away, Karen climbed up to her loft bedroom. Lighting a kerosene lantern, she intended on reading before going to sleep.

The memory of Terri's golden, sun-tanned body prancing casually around the cabin was burned in Karen's mind. She had tried constantly not to look at the teenager, but her eyes repeatedly drifted toward her lean, sexy body. And the shirt, unbuttoned completely so as to hide nothing, only made her look more than naked.

"Aunt Karen, Mack and I are going for a

walk," Karen heard Terri say. She made no move to look at her niece, but wondered if the girl would dress before going outside. "Do you mind?"

"No, but don't be gone long," Karen said. "It's going to get dark soon."

"We'll be back before you know it," Terri answered.

Outside the sun was fading, filtering through the leafy trees, casting shadows over the teenagers. Terri felt positively exuberant being outside without any clothes—save her unbuttoned shirt and shoes. She was horny, as usual, and the prospect of getting finger-fucked by Mack until she pumped out her pussyjuice had not escaped the hot-blooded blonde.

Neither said anything as they headed down the winding, narrow path, moving unconsciously toward the spot where they had first jerked each other off. When they reached the spot, Terri leaned against the three, looking at her brother with undisguised hunger in her eyes.

"I need you to . . . help me again," she said softly, her voice a husky, impassioned whisper. "Do you mind?"

"No, of course not." Mack was staring at Terri's tits, hungry for the taste of their ripe sweetness. "But getting a hand-job isn't going to be good enough this time, Terri. I need more than that."

Terri shivered, feeling the coarse bark against her back. She spread her feet slightly, her cunt becoming cooled by a gentle breeze. Her cunt was hot and ready for Mack's finger. But if getting jerked off wasn't good enough for him anymore, what did he want?

"Do you want to fuck me?" Terri asked, a trembling quality to her words. "Wouldn't that be incest?"

Mack moved closer to his sister, his eyes blazing with burning lust. "There is more than one way to skin a cat, you know." Mack was standing so close to Terri that he could smell her perfume. "What I propose is that we play a little game." "O-Okay."

"It'll work like this. Neither of us would have anything to do with the other if we had others around. You know, we wouldn't be making it with each other if you had your boyfriends around or if I had my girlfriends. We're essentially just bodies needed by the other."

Mack raised his hand, gently cupping Terri's right tit, feeling her quiver at his touch. The nipple became noticeably harder in his palm.

"Just think of me as a machine. I'll do anything you say, and while I'm doing it, I'm not really your brother, I'm a stranger. And as long as I don't put my cock in your cunt and cum inside you, it's really not incest. At least that's the way I look at it."

Terri's brown eyes were misty with excitement and confusion as she tried to comprehend exactly what her younger brother had in mind. He had changed, Terri noticed, since having shoved his fingers deep up her pussy until she came. She wondered what weird and exciting things he would have her do to his cock.

"You were first last time," Mack continued, "so I'm first this time. Close your eyes and forget that I'm your brother. I'm going to forget that you're my sister. From this point forward, you're just a machine—an object of pleasure—and you'll do everything I say ... or face the consequences."

Terri pushed her fingers through her hair near the temples, flicking all that honey blonde arms over her shoulders. The itching sensation from Mack's fingers working on her nipple was making her cunt creamy and hot again. She knelt slowly, closing her eyes as she settled her knees carefully into the lush grass.

"Okay, I think I understand the rules of the game now," Terri whispered, letting her hands drop to her sides. "I'll do whatever you say."

Mack placed his hands on Terri's head, standing straddle-legged so his bulging crotch was near her face. A breeze played with Terri's hair, fluffing the silken strands over her shoulders.

With her eyes closed, she did not know what to expect of her brother. But whatever it was

that he wanted, she would give. Terri would give willingly, wantonly, using every inch of her body if necessary to please Mack completely.

"You'll have, to tell me everything to do," Terri whispered, fidgeting as she placed her hands on her thighs, ready to open her mouth for the huge cock's entrance.

Mack pushed his cut-offs down and stepped out of them. His prick sprang out mightily, rigid as a steel pole, the head pink and round. Grabbing his cock by the broad, pulsating root, Mack brought his cockhead closer to Terri's slightly parted, moist pink lips.

"Ohhhhhh! Sweet girl, this is going to be better than either of us imagined," Mack hissed, the excitement rising to fiery levels in his body.

When she felt warm meat touching her lips, Terri allowed the tip of her tongue to flick out briefly. At the first taste of her brother's delicious, prickmeat, she crooned lustily and hungered for more. But it was not to be. Instead, Mack rubbed the spongy tip of his cock against Terri's face. She whimpered softly, keeping her eyes closed as the cockhead pressed against her lips, cheeks, nose and eyelids.

"Yeah, this is going to be hot," Mack whispered, stroking his prick as he worked the head against Terri's face. "I'm going to shoot out a fucking gallon of cum! You can count on

that!"

"I'm yours," Terri replied, her mouth remaining open, a blatant hint for Mack to shove his cock inside. "I'm your sex machine, your play thing. I'm here to do anything you—"

"Ohhhhhhhh!" Mack sighed, shoving four inches of his prick into Terri's luscious, wet, hot mouth. He shivered from head to foot, his knees trembling as he felt her slick, frisking tongue working on the clefted underside of his cockhead.

"Mmmmmmmmm!" Terri moaned. Her lips were ovaled around the huge cockpole. The fat, bullet-shaped head of Mack's prick was at the back of her mouth, filling her hot oral cavern completely, almost blocking off her breathing.

"Just stay there. Don't move. Suck on my cock and that's it."

Terri wanted to piston her beautiful face to and fro to gulp her brother's hot, salty prick in and out of her mouth. Instead, she followed his commands completely, getting great satisfaction out of chewing on the rigid shaft with her lips and using her restless tongue to probe and excite the cockhead.

Then Mack started pumping his hips slowly, fucking his prick in and out of Terri's luscious mouth. She salivated freely around the undulating cockpole, adoring the way the ten-inch prick stretched her lips and drooled

pungent pre-cum onto her tongue. "Mmmmmmmmmff!" the teenager moaned, shafting the driving cock with her lips. Her cheeks were concave, conforming to the jaw-stretching thickness of the huge prick that sprouted from Mack's body.

Terri wanted desperately to use her hand on the cock. It was her style to stroke big cocks while she sucked on them, adding more stimulation to the meat than just her lips and tongue could provide. But since her brother had not asked her to do that, Terri tried to please his red-hot prick as best she could with just her mouth.

"That's it! That's right!" Mack sighed, jerking his hips back and forth faster, driving his prick into Terri's mouth until the cockhead slammed against the opening of her throat. As he fucked her face, he leaned over her head, reaching around her body to cup one full, firm tit.

A bubble of spit formed at the corner of Terri's mouth. It grew in size, then burst, the spittle trickling down the teenager's chin as she sucked hungrily on the prick. Terri squeezed her thighs so hard her knuckles turned white. Having such a big prick reaming her lips and flattening her tongue to the bottom of her mouth without having the power to stroke it or caress and lick the twin balls that swung loosely between Mack's powerful, quivering thighs, was a kind of delightful torture. The

hot tingles coming from her sizzling nipples made her squirm and she pushed her tit harder into Mack's massaging hand.

Mack laced his fingers into Terri's golden hair again and started pulling and pushing her face to meet his undulating hips. His sizzling, spitty prick jabbed deep into the teenager's sucking mouth. As his excitement rose, the cum in Mack's balls simmered, getting hotter with each urgent thrust into Terri's mouth.

"It won't be long now," Mack hissed, his eyes glazed over with lust as he watched his prick sliding between Terri's lips.

The sight of his very own sister with a huge prick in her mouth was the most stimulating thing Mack had ever seen. And the fact that the big cock stretching his beautiful sister's lips was his own made it all that much more invigorating.

Terri's dancing tongue worked miracles on Mack's undulating prick as it slid to and fro in her wantonly sucking mouth. Occasionally Mack would pull her face toward his body as he lunged his cock into her mouth, causing the cockhead—which was the size of a small apple—to jam down her throat. She choked and struggled to maintain her composure, unwilling to allow herself the relief of taking the prick out of her mouth for even a second.

The pre-cum was oozing heavily out of the slitted pricktip. Each new drop fired up the blazing heat in Terri's cunt. She found herself

thirsty—actually thirsty—for her brother's sticky jism.

Faster and faster the prick sliced between her clutching, kneading lips, snapping Terri's head backward whenever the cockhead entered her throat. Her breath wheezed through her nostrils as she struggled to maintain her composure while her brother's heated, impassioned lunges became increasingly wilder.

"Ohhhhhh! Oh, fuck! Fuck! Fuck! Fuck!" Mack grunted, reaming Terri's hot mouth with jackhammer strokes of his cock. The sound of her wet mouth getting crammed full of his meat drifted up to Mack's ears, delighting him almost as much as his sister's frisking tongue.

"Mmmmmmmmm! Ummmmgg! Ummm!" Terri moaned happily, savoring the taste of Mack's pre-cum as it smeared off on her pink tongue. The huge prick glided to and fro in her cum-hungry mouth. Terri's big, creamy tits rolled crazily on her chest, the nipples hard, as she was tossed back and forth by the fat prick stuffed deep into her face.

"Don't worry ... I won't ..." Mack said, struggling to get the words out clearly.

His balls were bulging with pent-up cum and his red-hot cock felt like it was actually on fire. He wanted to tell his sister that he wouldn't cum in her mouth, but the excitement he felt made his mouth dry. Words were an impossibility.

Won't what? thought Terri, sucking furi-

ously on the pulsating, throbbing column of cockmeat that jerked between her moist, tingling lips.

"Awwwwwwwwww!" Mack hissed. He grabbed a handful of hair at the back of Terri's neck and jerked, snapping her head back. At the same time he wrapped his hand around the spitty prick and pulled it from the hot, wet recesses of her mouth.

Terri groaned, trying to get the delicious prick back in her mouth. It hurt to have her hair pulled and her head was bent backward at an uncomfortable angle. When she noticed the look of agonizing ecstasy on Mack's face and saw the speed at which his hand blazed over the huge prick, she knew what was happening.

Just as she expected, a long stream of jism erupted mightily out of Mack's flexing prick-tip. The cum sailed through the air, splattering against Terri's face, striking her on the cheek-bone, just below the left eye. A torrent of sticky, gooey cum shot from the fat cockhead, showering the beautiful teenager with a river of cum. Thick, pungent blobs of cream splattered over her cheeks, lips, nose and chin, it struck her golden neck and dripped onto the quivering moons of her tits. Terri, her mouth open obscenely wide, rolled her tongue around her lips, scooping off as much salty spunk as she could. Some thick, syrupy blobs of cum landed in her mouth and she swirled the delicious drops of fuck-cream

around, savoring them like fine wine before swallowing them greedily.

When he was finished cumming, Mack released his sister and staggered backward, his legs so weak they threatened not to support his weight. He had made a mess of Terri's face, , and even her neck and tits were dotted with his yellowish spunk.

"I ... I didn't want to cum in your mouth," he sighed weakly, leaning against a tree. "I know some women don't like that."

Terri was just about to tell Mack that she positively adored the taste of cum, and that if he ever wanted his ten-inch cock sucked, she'd give him the hottest blow-job of his life—any-time, anyplace. Then Terri remembered Mack's initial hesitation and decided that being too open about her horniness might frighten him away. She began wiping off the jism from her cheeks and nose.

"It's okay. Remember we've got to do whatever the other one asks," Terri said, suppressing a smile as she remained kneeling in the lush grass. "We're machines for pleasure. Love slaves. I'm your toy to do with whatever you choose." Terri rubbed the cum into her tits and face like cold cream. "Now it's my turn to make the rules. Get down here and lick my cunt. I want your tongue working on my clit, boy, or you're in big trouble!"

Mack quickly got down on his hands and knees, more than happy to lick his older sister's cunt until the slick pussy juice flowed against his tongue.
