Two days later, during their lunch break from the office, Susan and her Uncle Mark decided to take a leisurely walk through the large park just a block away.
They held hands and walked slowly through the nearly secluded greenery, talking now and then, but otherwise sharing companionable silences.
Suddenly, Susan stopped walking and turned to face her uncle squarely on.
"Uncle Mark," she whispered breathlessly, "I want to give you a blow-job!"
"Here? Now?" the man asked, shocked and more than a little turned on by his niece's lewd words.
"Sure! Right now!" the young girl giggled, gesturing toward a circular cluster of trees with a clearing in the center. "Over there. No one'll see us, and it'll make it all the more exciting to do it right there where we could get caught!"
Mark eagerly nodded his head and followed his horny niece into the grove of trees. There, Susan turned and faced her handsome uncle. She wrapped her arms around his neck and pressed her soft young body up against his. Mark's prick leaped in his pants and throbbed painfully up against the girl's flat tummy. He fastened his hungry lips on hers and explored the inside of her wet mouth with his hot tongue.
Susan reached between the man's legs and stroked the growing cock-bulge at his crotch. Mark ran his hands up under her skirt, and kneaded the tender flesh of her ass. She pulled down on his zipper and slipped her cool hand inside the hot cavern of his open fly.
Mark groaned when he felt the teenagers fingers touch the hard meat of his throbbing prick. His hard-on was almost at its full length now and she had to work his tock around a bit to get it out of his pants. His prick stood straight out, pulsing wildly in the air, pointing straight at the girl's tummy.
She took a step backward, and her eyes widened as she stared at her uncle's prick which by now was no stranger to her, but which never failed to excite her beyond belief.
"My God, Uncle Mark!" she gasped, running her soft hand up and down the long sleek cock shaft. "I'm always surprised by how big your cock is!" She shook her head in amazement.
Mark smiled proudly as Susan dropped to her knees. She licked her lips in anticipation of tasting the big red cockhead aimed at her mouth.
She stuck out her long pink tongue and teasingly licked the sensitive underside of Uncle Mark's cock-knob. He held his breath and cupped her head in his hands as she licked around the glistening meat of his prick, sending hot sensations coursing through his throbbing prick.
Susan squeezed his thick, round cock shaft and closed her eyes in ecstasy. She slipped her moist red lips around her uncle's prick and began sucking on it.
"Oh, yeah, baby, you've got it… just right. Yeah! Just like that… ahhhhh! Susie, keep it up… suck me off!" Mark groaned.
He stared down, watching with excitement as the girl's lips opened and closed around his cock. He was enjoying the sight of his own niece sucking him off.
The young girl slowly, skillfully milked the long cock shaft as she held the tender prickknob in her mouth and washed her hot tongue back and forth across his sensitive cock meat.
Oh God, Mark thought hotly, if only they were someplace else so that he could fuck his prick deep into Susan's hot cunt. He knew from experience that her pussy was just as good at milking his cock as her mouth was.
As his pleasure and desire intensified, Mark began moving his hips around. His knees wobbled and he could feel his entire body trembling.
Mark held the back of Susan's head and started to fuck his prick in and out of her expertly sucking mouth. Sensing that her orgasm was just a few sucks away.
The teenager dropped her hand from his prick shaft and pursed her moist lips in a tight circle around his cock.
Mark was fucking her mouth in earnest now. His eyes were closed and his mind was filled with hot images of his prick ramming her young cunt and hosing down the clenching walls of her pussy with cock cream.
He rapidly fucked his prick in and out of her mouth, his strokes faster and more frenzied now as his sexual tension increased. He shoved his prick deep in her mouth and held the cockknob fast against her tonsils as he brutally ground his hips against her mouth.
Susan groaned excitedly as her uncle's rock-hard prick suddenly bulged inside her mouth. Her lips worked furiously on his prick. Mark's body stiffened as he shot a thick stream of white-hot cum into the girl's mouth. She moaned again, greedily swallowing down his cock cream with loud sucking sounds.
"Oh, God, sooooo good," Mark groaned. His cock leaped and throbbed in the young girl's mouth as his milky cum spurted from his prick. Still sucking hard, Susan closed her eyes tightly and groaned out deep sounds of pleasure.
Mark pulled back and pried his cock loose from his niece's lips, feeling his legs trembling after his powerful orgasm. His well-sucked prick bounced in the air, trailing a thin string of cum which hung from his cockhead.
"Ohhh, Uncle Mark," Susan panted, staring at the cum that was dribbling from his cock. Then, she moved forward again and licked up every last drop of the man's delicious-tasting jism.
That done, she looked up at her uncle with a happy grin on her lovely young face. She put his prick back into his pants and zipped him up. Then, hand in hand, Susan and her uncle walked back to the office, not saying a word, but now and then exchanging secret meaningful smiles.
Late that night, Susan let her uncle into her bedroom, just as they had arranged it after their suck session in the park. She clapped her hands when she saw that he was carrying his whip.
"Ohhh, goody, I love it when you use that thing on me!" she cried.
"Hush, Susie. You'll wake everyone up!" Mark said, his eyes already gleaming with desire.
"Oh, that's okay. I told you how we've all been sucking and fucking each other lately. No one would mind," Susan said, taking her nightgown off and sprawling on her bed.
"Yeah, I know, but then I might have to share you with someone – and right now I want you all to myself, you filthy cunt!" Mark growled, taking his clothes off and walking menacingly toward the bed.
At first, her uncle's cruel, crude words shocked Susan. But then she grinned, realizing that the man was simply beginning their little game, the game that they both loved so much, the game that gave him permission to use the whip on her.
"Well, baby, are you gonna let your uncle fuck you or not?" Mark asked.
Susan could see by the light in his eyes that be wanted her to resist him so that they could continue their little game and play it out to the hilt.
"No, no, I hate you! I won't let you fuck me!" she responded, squirming on the bed as if trying to escape – when actually she wanted nothing more than to feel the man's huge cock fucking into her already-wet cunt.
"Look, baby," he said huskily, "You're gonna get fucked, no matter what you do!"
He leaned down and tried to kiss her, but the young girl jerked her head from side to side, preventing him from getting close to her.
Mark reached out and slapped her several times, sending her head swinging from side to side as she cried out in pain. But he knew what Susan was turning on more and more, just as he was.
This time when Mark kissed her, she did not protest. He ran his tongue up and down her neck and under her earlobes. He moved his hand up to her heaving tits, squeezing the firm mounds of tit-flesh until she moaned.
He pressed her legs apart and jammed his knee into her crotch. She started violently and opened her eyes with shock. She began to struggle again and began hitting her uncle with her fist.
"Let me go, you filthy bastard! You lousy son of a bitch," she said, her free arm wildly flailing and striking blow after blow against his muscular shoulder.
Mark grabbed her arm and dug his strong fingers into her flesh.
Mark snapped the whip and she recoiled on the bed as if she already felt the punishing lashes on her back.
With his free hand, Mark held his big cock and pointed it toward her face.
"This is what you really want," he said. "I'm gonna stuff this fat cock up your cunt, you cock-tease!"
Susan gasped and closed her eyes, playing her part to the hilt. She was breathing heavily and her eyes were locked on the whip. Mark grasped the handle of the whip, the long leather thongs trailing on the bed. Then, he raised it in the air.
"Are you gonna let me fuck you now, cunt?" he asked.
Susan shook her head, never taking her widening eyes off the whip. Mark moved closer to her and brought the whip handle down hard on her slender thighs.
"Oh, no!" she screamed, tears of pain and pleasure welling up in her eyes. "Don't, oh, please don't make me."
Mark grinned and, reaching over her, his stiff cock brushing her face, he gave her a harsh whack on her ass. She screamed again and wriggled her smarting ass high in the air.
He slapped the whip handle down against her hands. She was whimpering and crying, loving every second of the treatment her uncle was dishing out. And she knew, just as Mark did, that when they finally did fuck, it would be better than ever because of the punishment he was dishing out with such pleasure.
He brought the whip handle down on her flushed ass again, leaving a long red welt on her quivering mounds of ass-flesh. His hard cock throbbed in the air as his eyes feasted on his niece's slim, sexy body. He took in the tight mounds of her ass and her smooth-muscled thighs and felt his mouth go dry.
He leaned against the bed and tried to turn her over, but she continued to resist him. He whacked her again across the ass. She jerked around on the bed. He hit her again and pulled painfully on her arm. This time, Susan allowed him to turn her over.
Her beautiful face was bathed in hot tears, but she was smiling. She drew her knees up and cupped her hands around her pussy, hiding it from her uncle's view. He whacked her across the backs of her hands and she jerked them away. Then he smacked the soft insides of her thighs three times in quick succession, the whip handle a dark blur as it struck first one thigh, and then the other.
Susan moaned and lowered her legs to the bed. Mark dropped the whip to the floor and climbed on top of her. He began kissing her all over the upper part of her writhing body. He ran his hands over her huge tits and licked the long, throbbing nips which hardened in his mouth. He sucked on first one tit and then the other, with his hand between her legs. At first, she kept her legs tightly locked together, but Mark brutally squeezed the flesh of her inner thighs, gouging into her and making her snap her legs open.
He rubbed her downy cunt fur and ran his fingers inside the deep groove of her pussy, not surprised to find it as wet as the inside of his mouth. He fucked his fingers up her cunt and she groaned. She tried to pull back, still playing the game, but he shoved his fingers farther up and clutched at the slippery walls of her pussy.
Susan began moving around on her uncle's fingers now, unconsciously moving her ass around slowly, then more passionately as his fingers probed her pussy. He bent over to kiss her again and this time she opened her mouth wide and tongue-kissed him back.
Still playing their, game as if reading a script, Susan suddenly bit her uncle's tongue. He screamed in pain and, rearing back, he slapped his niece across the face. He acted as if he were furious now. He roughly spread her legs apart and mounted her, fucking his swollen prick up her pussy and ignoring her cries of pain and pleasure as his huge cock scraped the insides of her cunt and grated against her soft flesh.
Susan came alive. She wrapped her legs around her uncle's back, thrusting her hips against his and making him wince as her crotch ground hard into his.
"Ohhh, Uncle Mark!" she cried, tossing her head from side to side, tears of joy and pain streaming from her eyes. "Ohhhh, take meee, Uncle Mark, take me! Hit me! Slap my face! Beat me hard and rape me with that hard cock of yours!"
Mark slapped her face back and forth, timing each slap to the rhythm of his cock as he fucked in and out of her cunt. She reached up and sank her long, sharp fingernails into his arms, and he shivered in both pain and delight, feeling the mounting excitement and girl beneath him.
"Fuck you, fuck you, fuck you," Mark chanted as he fucked his niece furiously, whipping her face back and forth as she cried and screamed and her beautiful face contorted with lust. The young girl gave herself totally up to the ecstasy of being raped and beaten, just as she always did when she and her Uncle Mark played their little game.
Mark unwrapped her legs from around his waist and draped them over his shoulder, her ass swinging freely off the bed now and her pussy open as wide as could be. He fucked his rock-hard prick deeper inside her cunt and roughly squeezed her thighs.
"Ohhhh, stop, stop!" she screamed. "I'm commmiiinnnggg!"
Mark felt the walls of the girl's pussy quiver around his buried cock. She shuddered and jerked around on the bed as she reached an explosive orgasm.
"Ohhhh, it feel soooo good!" she cried as waves of hot forbidden pleasure washed over her.
But Mark didn't stop. He continued to fuck in and out of her, goaded into a lusty frenzy and by the lewd sensation of the girl's orgasm filled pussy clutching at his cock.
Susan kept screaming and beating on the mans arms, flinging her head on the pillow, her long golden hair swinging through the air.
"Ohhhhh, nooooo!" she cried out deliriously. "I'm coming again! Oh, my God!"
Another orgasmic explosion shook her body as she came again and again, her slender body shaking spasmodically and her pussy muscles expanding and contracting around her uncle's cock shaft. He fucked his prick as far up her pussy as it would go, and held his prick in place as he ground his crotch into hers.
"Ohhh, Uncle Mark, please come inside me!" she cried out, her mouth wide open and her saliva running over her lips and down her chin. "Oh, come now! I can't stand it anymore! I have to feel your cum inside me!"
Mark pulled back and withdrew his cock until it hung just outside the girl's slippery fuck hole. Then he fucked back in until just the cock head was inside her, then withdrew it again. He slipped his prick-knob in and out of her fuck hole, sliding his cock back and forth over her cuntlips, tickling her clit and driving her mad to have all of his big prick inside her again.
With his cockhead rapidly flexing in and out of her cunt, she came again, her warm, slick pussy cream pouring over his cock-knob and running down the shaft of his prick.
"Oh God, Uncle Mark, don't keep teasing me like this! I can't stand it! I have to feel you coming inside me!" Susan cried desperately.
Mark fucked deep inside her, jolting her body with the force of his fuck-thrust. With her legs still wrapped around his neck, he tugged at her hips with each thrust of his huge prick, his balls smacking up against her ass with a sharp, wet sound.
His cock seemed to expand inside her cunt as his cum shot up from his balls and gushed out his cum-slit. Feeling his cum spurt inside her pussy finally, Susan came all over again. The muscles of her cunt opened and closed around the man's pulsing prick as every last drop of jism was drained from his balls.
Susan opened her eyes and smiled up at her uncle. She put her arms around Uncle Mark's neck and hugged him to her. Her lips brushed his forehead as she ran her fingers through his thick hair.
"Thank you, Uncle Mark," she murmured. "I love it when a guy takes me and forces me to him fuck me. I love the way you rape me sometimes!"
"My pleasure, baby," Mark said with a husky chuckle. "Just give me a call anytime you feel like being raped!"
