John Kellerman - Sisters in heat

"Nat! You won't hurt me-me, will you?"

Nat caught her head, turned it, strained to reach her mouth. She twisted her own face and they kissed in a teasing, hot moment. Then he rolled her gently onto her side. He was moving his pelvis in short, sharp jabbing motions.

Each time he moved she could feel that cock spearing her, could feel it forcing its way into the strained, wet tunnel of her cunt. Her uncle's wonderful fucking bordered on the edge of pain. But the discomfort was heavily laced with turbulent pleasure.

She couldn't hold her hips still, pain or not. She felt him rolling her onto her belly, felt him part her thighs and work his own between them. Her asscheeks were against his belly as he worked his prick deeper into her pussy.

Now she was face down in the sleeper, her tits swollen against her uncle's cupped hands as he fucked her from behind, gentle now as if he wanted to be sure she would be able to take his cock. Marcia felt his lips at the nape of her neck.

"Marcia… baby…"

He wet her face. She could feel his rooting, thick prick and the way her asscheeks were flattened against his lower belly. When he pulled back, she felt her cunt being yanked along with him. It was as if that barb, that taut fleshy barb had speared and caught her. The only way she could ever be freed would be for Nat to jet his seed deep into her cunt.

She bit her lip as he fucked himself deeper. His cock was a little over halfway inside her body and miraculously she was taking him.

"Ahhh… Uhhhh!"

She bucked her hips, arching her back sharply and pushing her lovely ass high. This angle seemed to open her cunt more, seemed to bring new floods of lubrication.

Nat slipped his fingers away from her nipples and slid them down her sides. She felt him grasp her firmly at the hips and lift her… he was up on his knees.

"Ohhhhh!" She gasped with the excitement of the new position. Like dogs they were. She spread her hands out to support herself.

Nat was holding her pelvis firmly, guiding his prick perfectly into the wetness of her pussy. She heard the slick sucking noise as he pulled back. Then he fucked powerfully. Her cunt was wet enough now, hot enough.

She felt the huge shaft gaining two inches, three. The friction around her cunt where the flesh was pulled tight was about to make her scream. Every nerve in her body seemed focused on this huge cock that was pushing her soft insides around to make room. Oh God, Nat was really a man! She felt like surrendering to his every wish. And what made it better was that she loved him so much, had loved him all her life.

"Uhhhh… Nat," she babbled, wanting to tell him everything she felt. "Your cock's so big inside me and so hot! I can feel the way your tip swells out… I can feel it making room. Oh I wish I could see it too." She laughed, sucked a ragged breath. "I love your prick, Nat… Ohhhh God! Darling!"

He had pushed his body up against hers. His cock was deep. Very, very deep. And when she tensed the muscles of her cunt, she felt the soft, feathery folds caressing his shaft and tip. Nat licked her back wildly. His hands stretched for her tits. It was as if he wanted to touch all of her at the same time.

Marcia didn't know how she was rolled over. She only just found herself being turned in Nat's loving arms, rolled around so that her leg had to be doubled back to clear his body and then she was on her back, both feet pawing the low roof of the truck's sleeper as Nat began to work the last inch of his cock into her steamy young pussy.

"Ohh… Oh… Oh… Uhnnn… good… fuck… Ohhhh fuck…" She pulled wildly at his hair, kissed his face as the big cock gouged into her cunt.

Marcia felt the bulging, taut glans nestle finally against the very mouth of her womb. That tiny little knot that was the end of her pussy. And then he fucked her gently as his heavy balls pushed tight against the lower part of her vulva.

New rushes of cuntjuice flooded out to wet his balls. Whimpering with fever, Marcia pushed her hands down and felt the place where her cunt had been stabbed, so full. She traced the circle of her inner cuntlips where they stretched around the big cock. And her outer cuntlips were swelled tightly around it too, seeping juice at the edges. There was nothing left! She had him all… all of his cock inside her!

Nat held her head with one hand and her ass with the other as he began to fuck her strongly. She lolled her head back and opened her mouth for him to suck. They loved each other's tongues and gasped hot words.

Marcia felt his powerful hips stroking the thick, hot beast of his cock in and out. When it was almost all the way out of her pussy, she felt that her insides had sucked into a tiny, wrinkled balloon. But then he plunged deep and filled her with cock.

She wiggled and flopped her trim ass, giving him her thighs, her belly, her tits. She wrapped her feet behind his back and locked them so she could hang there as he fucked furiously.

She felt her first come building. Her pussy convulsed around Nat's penis. She grabbed for his balls to fondle and knead them. Her come shot through her cunt like a hot bolt of lighting. Nat felt it too, felt the way her cunt tightened suddenly at the base of his prick. But even as that short, sharp chunk of pleasure was fading, she felt another behind it.

Coming… coming… it would be bigger than the first!

"Nat. Ohhhhh Nat! I'm g-g-gonna come again! Oh Jeeeesus!"

"Marcia… I don't want to get you in trouble, honey… I think I…"

"Oh no Nat… come inside me! You can! You can!" She could hardly speak through the rising storm of her lust. "My… period… tomorrow probably… Oh Nat… come!"

Marcia was straining every muscle, moving her whole body in a dozen different directions. She raked at her lover's back with long nails, bit at his shoulder. She humped her young ass tip and down, rocking her pelvis to make the angle of his steely cock hurt her a little.

The big cockhead was stretching her cunt. She'd never be the same and she was glad! When he dragged his cock back to fuck deep again, Marcia made her pussy tighten around the ridged crown, made it bathe the sensitive membrane with her hot, slick juice.

Nat grunted and shoved deep again. Their wild pleasure twisted them onto their sides. Then Marcia found herself on top for a moment. She kissed and drooled into Nat's mouth, babbling again how much she loved him. She pushed her big tits down onto his chest so he could feel the hardness of her nipples. She rocked herself on that rigid cock as the slick cuntjuice slurped, around his prick. She was so close now… only an instant away and yet it seemed to hang there. It was maddening. And lovely. And the best thing in the world.

"Uncle Nat," she sobbed, coming apart with the frenzied hunger inside her cunt. "I think I'm gonna die…"

She closed her thighs, fucking violently. The increased pressure made Nat grab hard at her humping, dancing ass. His fingers slipped along the crack, sunk into the hot whorl of her asshole.

Marcia arched back, quivering. The moment was upon her. In her furious flight toward paradise, Marcia fucked with the throes of a person gone insane. And as she squirmed and hunched, Nat's cock slipped from her pussy.

"Ohhhh… Ohhhh help, Nat help!"

She grasped for the slick cock with both hands, poised on her knees as she struggled to get it back inside her cunt. She was looking directly down on the pulsing, purple head when a stream of hot jizz shot against her clitoris. That heat and force made her convulse weakly with the first spasm of her final climax.

Nat seemed to know she was too far gone to push his cock back into her cunt. He rolled her over with a growl, forced her quivering thighs apart with strong fingers.

Marcia screamed with ecstasy as she felt the glossy prick divide her cuntlips and sink quickly into her pussy. She came! Whining and bucking and writhing around the lovely hard cock that speared her deep.
