Kathy Harris: Naughty horny family

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.
