Chapter 3
The next few days were heaven on earth for Kim. She and her brother sucked and fucked at every opportunity. Then, much too soon, the time arrived when Pete had to return to College.
"Do you really have to leave me?" Kim asked her brother as he packed, knowing full well that she couldn't hold him.
"Final exams." Pete shrugged. "No way to get around them short of flunking out. But when they're over, I'll be back home again. We'll have the whole summer together, Sis."
"I'll be climbing the walls until you come back," Kim sighed.
"Don't do anything I wouldn't do, Sis," Pete smirked with a wink.
As Kim asked him what he meant by that crack, her brother snapped his suitcase shut. Before Pete could answer, there was a knock on the door.
"Hurry up, Peter," Mrs. Baker called to her son. "Your plane takes off in less than an hour."
"Mom's right," Pete told Kim, "have to get a move on. You driving to the airport with us?"
"I'd better say goodbye now, before I start bawling," Kim replied.
"One last kiss, Sis?"
"Kiss? I want more than that," Kim pouted.
"A kiss is all we've got time for," Pete insisted.
He leaned down to offer his mouth. But Kim ignored it. She went straight for her brother's fly. Before Pete could react, his cock was out.
"Let go, Sis," Pete protested.
"No way," Kim purred.
She was on her knees now. Her lips and tongue were all over her brother's prick. She licked and nibbled, playfully humming as she did so.
"You've got to be crazy," Pete muttered.
"Your cock doesn't think so," Kim slurped, drawing attention to the fact that her brother had a hard-on.
"Okay," Pete admitted. "Maybe we've got time for a quick blow-job."
Kim had more in mind than just sucking her brother's prick, but she didn't say anything to scare Pete off. She closed her mouth over the head of his cock and applied suction, counting on getting Pete so turned-on that he wouldn't be able to resist her. Before her brother departed, Kim had her heart set on one last fuck.
In the meantime, she concentrated on the blow-job. Her lips slipped farther and farther down Pete's hard-on. Finally she was deep-throating her brother and Pete's hips were rolling.
Before long, the blow-job had progressed to a more advanced stage. Pete was fucking Kim's mouth.
There was another knock on the door.
"Peter," Mrs. Baker called again, "aren't you ready to leave yet? It's getting late, Son."
"Five minutes, Mom," Pete replied in a controlled voice that gave no hint that the delay was caused by his sister sucking his cock. "Give me that long and I'll be ready to go."
"See that you are," Mrs. Baker huffed. She walked away from the closed door, her footsteps clicking down the hall.
"You heard mom," Pete told Kim. "We've got to get this over with."
Kim sucked harder. However, not with the goal of making her brother come in her mouth. She wanted Pete's prick on the brink of eruption, for sure, but only so she could gather the momentum to persuade her brother to come somewhere else. By the time Pete left for college, Kim was determined that her cunt would be dripping with his jizz, Pete had no idea of this, though. He thought he was getting away with plenty just fucking his sister's mouth. And right now his balls were churning with liquid heat.
"Gonna come before long, Sis," Pete rasped. "Come in your mouth."
"Right and wrong," Kim responded, abruptly releasing her brother's straining hard-on before his prick could erupt. "Right, you're gonna come. Wrong, that it'll be in my mouth."
"What the hell?" Kim's confused brother gulped.
Kim was on her feet now, standing up against Pete. She slid her hands inside her jeans, popped them open, and forced them down her legs along with her panties.
"You're going to fuck me before you leave," she told her brother as she caught his stiff prick between her thighs and gave it a squeeze.
"No . . . no," Pete choked. "Too risky to fuck you. Not enough time."
"Nonsense," Kim insisted. "After that blow-job I just gave you, your cock's all pruned for a quick fuck. Besides, it'd be a shame to send you on that long plane ride with a case of lover's nuts."
Kim reached down between her legs. A quick adjustment and her brother's prick was in her cunt.
"This is insane," Pete panted.
"But it's tight and warm and wet," Kim said, referring to the forced union of her brother's cock and her spasming cunt. "And it feels so good."
She socked her crotch against her brother's groin, burying Pete's prick to the hilt inside her. Wiggling her ass, she turned on the friction.
"Still wanna stop fucking me, Pete?" she teased.
"No," Pete admitted. "Too late to back out now. You've got me trapped."
"My, aren't we romantic," Kim giggled. "Looks like you still need some thawing out."
She took her brother's hands, pushing them up under her blouse. As usual, she wore no bra. Pete's fingers clutched her tits, his nails sinking into the soft flesh.
"Oh, that's it," Kim moaned. "Claw my tits. Give me some pain to go along with your cock in my cunt."
"You want it rough, Sis?" Pete impulsively rasped. "Okay, I'll give it to you."
"Is that a threat or a promise?" Kim egged her brother on now that she had him fucking.
"A fact," Pete snapped.
His cock fucking in Kim's cunt, Pete forced his sister up against the nearest wall. He grabbed fistfuls of her blouse from the inside and tore them apart.
Kim was delighted.
"Rip me ... rip me," she gasped.
The blouse was quickly shredded and gone. Pete clamped his mouth on one of Kim's tits, using his teeth.
"Oh, yes. Bite me ... bite me!" Kim groaned as a sharp pain spread through her tits.
Pete punctured the skin. When he removed his mouth from his sister's tit there was a pocked circle of tooth-marks surrounding her nipple.
Her brother started chewing on her other tit. Through it all, Pete's cock drove in Kim's cunt, as brother and sister fucked standing up.
"Mmmm, you're so mean to me," Kim noted with glee. "I like you this way best of all. Makes me think you really care."
"Horny damn bitch," Pete growled with a mouthful of tit.
"When you get back to college and get the hots for some coed," Kim continued, "just remember what you've got at home. Other girls put out, Pete, but only your own little sister does anything."
Pete grunted. Kim squealed with welcome pain. She was rewarded by a savage cock-thrust up her pussy that bounced her ass against the wall.
This brought the clatter of footsteps in the hallway outside and another knock on the bedroom door.
"What in the world's going on in there?" Mrs. Baker called. "Sounds like you're trying to tear the house down."
Hearing his mother's concerned voice, Pete pulled his mouth from Kim's tit and answered, "Uh, just trying to get my suitcase closed, Mom. Had to jump on it."
"Well, keep it down. And, for heaven's sake, Peter, hurry up," Mrs. Baker said with exasperation.
"Sure, Mom."
The footsteps went away again.
"You should see yourself," Kim laughed at her brother while he sighed from the close call.
"Just shut up," Pete snapped with embarrassment. "Do you wanna fuck or play games?"
"Oh, macho, I guess," Kim taunted.
Pete slapped her. Kim laughed so he slapped her again.
"That's right," she mocked. "Knock my head all the way through the wall. Then mom'll come running, bust right in here, and everything'll be right out in the open."
"I don't think you'd really mind that," Pete spat.
"You got the guts to find out?" Kim answered.
"No," Pete admitted.
"Then don't get even with me by hitting me," Kim said. "Use your cock. Fuck me. Drive your cock right through me. Fuck me until I beg for mercy."
Pete swung his sister away from the wall. His cock tore loose from her cunt in the process, but it was clear that he wasn't ending the fuck, just getting set to accept Kim's dare to intensify it.
Kim was grabbed by the shoulders and shoved toward a chair where she was forced to her knees. Pete grabbed a handful of her long blonde hair and slammed her face against the seat.
"A bitch like you deserves to be rucked like a bitch," Pete hissed.
He lifted his sister's ass in the air then kicked her thighs apart. With her flanks spread so her cunt flexed from the rear, Kim resembled an animal in heat.
"You dog-fuck a bitch," Pete kept hissing.
When his cock fucked into Kim's pussy once again, the penetration was from behind. Pete hunched over his sister's back, his hot breath making the hairs on her neck stand up as his prick went to work.
Kim had been fucked in this position before, but never had it affected her this way. Her animalistic urges came to a boil. The moan that was wrenched from her throat was not human.
Kim fantasized that she was a small dog being fucked by a much larger one. She had once seen a Great Dane trying to fuck a tiny white poodle, and this was the vision she held on to while her brother dog-fucked her.
She whimpered. She panted. And she took thrust after thrust of that massive prick up her tight cunt from the rear.
"Take it, bitch, take it," Pete snarled in her ear.
Kim felt as if her brother's cock might injure her. She didn't protest. Not hardly. As far as she was concerned, this was what fucking was supposed to be at its best. The ripping in her loins could only increase her capacity to come.
And come she did. With a blinding rush that turned her nerve-endings into live wires.
"So you're coming, huh?" Pete muttered. "Well, fine and dandy. Enjoy it, Sis--while you can. Ever hear of too much of a good thing? That's what's gonna happen to you. I'm gonna make you come so much you can't stand it. You'll beg me to stop fucking you."
Pete fucked his cock faster and faster. He brought his hand around under Kim's belly and fingered her clit. His other hand mauled her tits.
Pete not only didn't let up, but he increased his three-way stimulation of his climaxing sister. His prick fucked her pussy. Pinching her clit, he twisted it around double. One of his thumbs pushed one of her nipples deep down into the cushion of her tit, grinding the tender bud of flesh.
Equal parts of pain and pleasure had Kim torn between agony and ecstasy. She couldn't decide which sensation she enjoyed the most, the suffering or the sweetness. Fortunately, she didn't have to choose.
She concluded that she had it all. Other girls would kill to experience what she was going through. If they wouldn't, there was something wrong with them as far as Kim was concerned.
In the meantime, Pete still thought he could make his sister call it quits. However, time was running out on him. His cock had been scraping too long and too hard against the rippling walls of Kim's cunt for his balls not to get the message. They ached. The pressure from the cum they brewed growing with every cock-stroke.
Eventually, Pete recognized that he could hold off no longer. He either had to shoot his wad or quit fucking his sister.
Pete considered pulling out, just to spite Kim. He'd been mistaken to believe he could dog-fuck her to a standstill. But what if, just at the end of it all, he switched tactics and denied his sister's pussy of the cum it craved? That would teach the bitch who was boss.
But when he tugged at his cock, Pete found that his sister's cunt was like a vise. The friction just increased.
Pete's balls rumbled with complaint, demanding to be drained.
"Gotta come," he admitted to himself.
Kim overheard him and responded, "Then what're you waiting for, stud? Flood my pussy with jizz. Give me the goodbye present I want--a cuntful of your hot, sticky cum!"
Just as Kim finished speaking, the knocking on the door started again, more urgent than ever.
"Peter!" Mrs. Baker exclaimed, her voice peaking with agitation.
"Coming, Mom," Pete called back.
And coming he literally was. For his hilted prick had just erupted in his sister's cunt.
"Wow, you're coming all right," Kim moaned to Pete's unintentional play on words and the creamy torrent of jism in her pussy. "If mom only knew how you were coming."
"Shhh, mom'll hear you," Pete warned his sister in a whisper as his prick spurted almost a foot deep in her thirsty cunt. "She's still at the door."
After a moment of silent waiting, Mrs. Baker called to her son that she was going to get the car out of the garage. She'd be waiting for him in front of the house, and he'd better step on it or he was going to miss his plane.
Mrs. Baker stomped away with irritation. Left alone, her children were now in their final moments together.
Pete's cock had been drained. He pulled his prick out of Kim's cunt. She still wasn't satisfied. Pivoting around on her knees, she pounced on her brother's crotch and licked the stickiness from his tired prick.
"I'm gonna miss you so damn much," she said directly to Pete's cock.
"Don't kid yourself, Sis," Pete sighed, his voice heavy with sexual fatigue. "I can see now that you won't miss my cock any longer than it takes you to find somebody else to fuck you."
"You're full of it," Kim objected. "Just trying to give yourself a reason to fuck around once you get back to college."
"No, I'm on the level, Sis," Pete said seriously. "I just finished fucking you as rough and mean as I could ever fuck anyone. I wanted to put you in your place, I guess, teach you a lesson about being too horny for your own good. But you never gave an inch. No matter how hard I fucked you, all you wanted was more."
"But that was because you were the one fucking me," Kim excitedly replied. "I love you!"
"Correction. You love to fuck," Pete told his sister. "And as soon as I'm gone, all your good intentions won't be worth a shit. You'll get that old itch between your legs and find somebody to take my place."
"I won't!" Kim stubbornly insisted.
"Yes, you will," Pete stated with certainty. "Not that I blame you. It's in you, that's all, I can tell. You can't help it. Don't twist yourself into knots trying to be something you're not because of me. Whatever you do, Sis, I'll understand."
Just then the horn honked from outside.
"There's mom," Pete said. "Got to go. She's probably steaming."
He got up, stuffing his cock and balls back into his jeans. Then he grabbed his suitcase and backed toward the door.
"I won't fuck anybody else! I won't . . . just won't, no matter how horny I get!" Kim wailed.
"You may not think so now," Pete answered with a knowing grin. "But sooner or later you'll find a way to square it with yourself. The same way you must have done when old man Carlson took those pictures of you getting fucked."
"I had a good reason for that," Kim protested. "I was failing history. It wasn't like it was with you."
"When you were at Carlson's, you convinced yourself you were fucking your way to an A in history," Pete said. "But it was cock you were really after. And when I'm gone, you'll convince yourself you're spreading your legs for some other perfectly good reason. But it'll still be pure cock you want, whether you admit it to yourself or not."
The horn outside blared again.
"One last piece of advice, Sis," Pete said, opening the door to leave. "Be careful. A girl like you can get herself in a lot of trouble if she doesn't know her own mind."
"Bastard!" Kim screamed, in rage at her departing brother. But her voice was drowned out by the blaring horn. And Pete was gone now anyway.
Left alone, Kim put her hand to her cunt and felt her brother's leaking cum moisten her fingertips. This sticky reminder of Pete made her sob. She felt totally abandoned.
Suddenly she was a weeping child. She had herself a good, long cry.
