"Oooooooh, baby, stop it!" Steve suddenly moaned.
The boy's hands came up and forced the beautiful face to cease its obscene ride up and down his pulsing dong. He held Dawn's head in his hands and lay back sighing.
"No more, Sis, please. I… I really want to fuck you tonight. It's been a week since I shot in your pussy. I'll let you suck me off tomorrow night, I promise," Steve told his older sister in a hot, low whisper.
Dawn let her brother's rock-hard cock slip from her nursing lips with a loud pop. She grinned at him.
"Sure, honey," the long-haired blonde said with the same sense of urgency. "If you want to put this big, hot thing inside my little pussy, that's great with me!"
Lucinda thought her heart was going to stop beating. She couldn't believe what was happening in the bedroom, right before her eyes. Dawn couldn't actually be going to let Steve fuck her! Lucinda's mind recoiled with disgust at the very idea.
But Dawn's clearly did not. The voluptuous eighteen-year-old was moving up onto the bed, straddling her brother's reclining body and upraised dick. She put one hand on the base of Steve's cock and steadied it as she lowered her red, juicy cunt-lips onto his steely prick.
"Hot! Oh, Christ, you're a fuckin' volcano inside, like always," Steve murmured as her snug cunt slipped down onto his big cock.
Dawn moaned and let herself slide all the way down until her little brother's prick was jammed tightly up in her pussy. The radiant eighteen-year-old whinnied like a mare in heat just pierced by a stallion and began to jerk her curvy hips up and back over his penetrating cock.
Lucinda felt a rush of heat envelope her. Heat as intense as if an oven door had been abruptly opened and she had been thrown inside. Strange fluid was suddenly seeping out of her tiny cunt-hole, and her tits felt hot and itchy. Her nipples stood out against the fabric of her light nightie, throbbing with the need to be caressed.
The inexperienced little girl knew she should tear herself away from the keyhole and go get their father. At the very least, she knew she should go back to her room and leave her brother and sister to their fucking.
And yet she knew she wouldn't. The hot, pounding need in the young girl's loins, the pumping, aching insistence jetting through her nubile tits told her she couldn't.
Lucinda leaned closer to the keyhole, hoping to see it all.
CHAPTER TWO
Dawn leaned forward and placed her palms on her younger brother's shoulders. She steadied herself, then closed her eyes and really started to whip her pussy up and down over Steve's hard shaft. His crimson cock appeared and then disappeared up into her cunt-lips at an ever quickening tempo that soon had the boy growling and wiggling with lust beneath his sister's violent, greedy fucking.
"Unnnng! Jesus, Jesus, God, Dawn! Ball me! Fuck me hard and fast, like last time," Steve blurted mindlessly, obviously lost in the sensuous delight of his big sister's tremendous lust for his prick.
They bouncing blonde groaned and fucked him even harder. Dawn was plunging and heaving, her magnificent body shining with a light sheen of sweat, her head thrown back, her big tits jiggling wildly.
"Ooooooo, ohhhh, oh, God! Better," Dawn suddenly panted. "Even better than last time, don't you think?"
Steve grunted and thrust his hips upward, stabbing his long pecker up into his sister so far that she squealed with joy and rode him at an even more furious pace. The young boy grabbed the older girl by her spongy, luscious tits and pulled her down onto him by her jugs, his fingers digging into the pliant flesh until Dawn's tits looked ready to pop from the pressure.
"Oh, squeeze them!" the tawny-haired blonde whined in a frenzy of need. "Play with my big tit ties! Feel my nipples, Stevie, lick 'em as you – as you… ohhbhhh, fuck me!"
Sitting on the cold tiles of the bathroom, Lucinda was vaguely aware of something warm touching the insides of her naked thighs as she watched the lewd fucking of her older brother and sister. The little girl was panting, and she noticed, to her shock, that her hands had wandered up onto her tits, and that she was pulling at her tiny nipples just the way Steve was tweaking Dawn's tit-tips.
Lucinda didn't want to look down even for a second to see what the warm sensation along her ass and thighs was, but her curiosity got the better of her at last. Tearing her eyes away from the rutting, moaning couple on the bed, Lucinda looked quickly at the bathroom floor.
A small puddle of slick, hot cunt-juice was forming on the tiles between Lucinda's spread legs! The girl touched it and found the fluid to be very slick and warm between her fingertips as she rubbed them together. It had almost no odor.
Lucinda touched the crotch of her translucent pajama shorts and found them soaking wet. She pried the material out from her sleek belly and saw that her cunt-fur was matted with the hot oily stuff and that her tiny pussy was leaking the warm lubricant freely.
Reluctant to touch the gooey liquid at its source, the little girl made herself do it. Her fingertips grazed the top other shimmering pussy-mouth, inadvertently connecting with the small knob of flesh protruding out of its protective sheath – her… clitoris, if Lucinda remembered her sex education class vocabulary correctly.
A searing, blinding jolt of sensual pleasure shot through her cunt as her finger touched the tiny nub. It was all Lucinda could do to keep from shrieking out her pleasure as an overpowering spasm of joy tore through her virginal pussy.
Frightened by the intensity of her body's reaction, Lucinda took her hand out of her shorts and hastily brought her attention back to the keyhole, hoping the strange new sights and sounds there would distract her from the newfound joys waiting just inside her cunt-lips. She knew that it was terrible for a girl to "play with herself".
Dawn and Steve Collins obviously didn't give a hot Goddamn about what was right and what was wrong. Lucinda realized abruptly as she looked back through the keyhole. Steve was hunching up off the mattress with each thrust, really cramming his big prick up into his older sister's tight cunt with each new stroke. Dawn was enjoying every pussy-reaming minute of it, too. Lucinda could see that clearly from the expression of utterly depraved joy stamped across the lovely eighteen-year-old's face as she rode the fat cock frantically.
Lucinda felt hot waves of sensation flooding through her pussy as she watched the wanton display again. The hot feelings weren't quite as sharp nor as intense as the one that had tipped through her when she had first fingered her cunt, but they were quite thrilling all by themselves.
"God, if it feels this good just watching, and so incredible just touching myself down there…" Lucinda's whisper-trailed off. "How good it must feel, actually getting a big cock stuck up in there again and again, like Dawn is getting now!"
Lucinda shivered with lust at the mere thought of how terrific that must feel. No wonder Steve and Dawn were fucking each other, despite all the taboos about incest.
The little girl touched her nipples once again, seeing Steve lash out at both of Dawn's bouncing nipples with his long tongue. He coated both of her distended tit-tips with saliva and made the skin just below her areolas wrinkle. Dawn groaned and rammed her cunt down onto Steve's hard dick even faster.
"Oh, Jesus, Jesus God, you make my titties hot!" Dawn gasped.
Lucinda felt a hot prickle of excitement in both of her young tits as she took a nipple in each hand and twisted the way Steve had been doing. She wondered how it must feel, to have a cock up her pussy and a boy's tongue laving her sensitive nubs as he fucks her pussy.
The excited young teen decided to find out. She knew that as soon as she got a chance, she was going to let a boy fuck her. But right now, she wanted to find out as much as she could on her own.
