John Kellerman: Sisters in heat

Her Levi's came next. She kicked off her sandals too, snaked out of the tight blue denim. Then her panties. Nat might stop her at any moment. He might spank her good or even slap her across the face. She didn't know what he might do. But she couldn't stop.

It was hard being graceful in the cab of a truck, but she slipped the dainty silk panties off and hung them on the gear shift. Then so slowly that she could almost taste the tension of her uncle's body, she brought her hands up to frame his handsome face. She pushed her tits against his bare-chest and kissed him. It was a light, teasing kiss. She only brushed her lips over his at first, then dampened the corners of his mouth with her tongue. She breathed soft words as she gently nipped at his mouth.

She licked his chin, his cheeks, weaving her long fingers into his hair. Then she speared her tongue shyly between his teeth, pulled it quickly back and began kissing his hot lips gingerly again.

"Love me, Nat," she breathed. "Make love to me. I want to have your cock inside me, I want you to fuck me…" The word had slipped out so naturally. Marcia hid her embarrassment, kept on wetting his mouth with hers.

The second time she gave him her tongue to suck, he took it, pulled it deeply between his lips.

"You're beautiful," he gasped at last. His fingers traced the large, firm curves of her tits, her warm belly. Then he was sucking a nipple between his teeth.

Marcia gave a shuddering whine of pleasure, arched herself up to him. Her pussy flooded suddenly with juice, wetting her heel where she had it tucked beneath her body.

She climbed back into the sleeper. There was a tiny, glowing lamp that made it amber and cozy.

Nat unbuckled his pants. She heard his cowboy boots thump to the floorboard. And then he was climbing into her arms.

When the huge welt of his cock pressed into her thigh, she jumped. The fear she felt was a surprise, a shock to her warm need. She hadn't guessed Nat's cock would be hung like that! She was almost afraid to look.

Nat moved, rumpling the covers. She let her fingers fall down the slope of his stomach, pretended by accident to find his prick.

"You're… y-y-you're cock's really big!"

Nat rested on one side next to her. She didn't want to seem scared, but she couldn't resist having a look.

Marcia camouflaged her movements, kissed his chest and belly, then pushed her long hair out of her eyes and stared. In the amber glow of the sleeper, she could see his prick clearly. Thick and uncircumcised. The foreskin covered all but the very tip of the glans and even as she watched, the head swelled with blood, the foreskin slipping back some to expose the purple gloss of meat.

As near as she could tell, Nat's cock was close to eight inches long and at least two and a half inches across. The glans was even thicker than that. Her uncle's cock made Sam Philbert's prick look like half a popsicle. And Nat's balls were in proportion to the rest of him.

Marcia was shaking and knew she had to hide it. But how would she ever be able to take that cock inside her young body? Even Sam's cock had felt tight inside her pussy and she was sore afterward. But this… this…

Nat held her hair up so he could kiss the nape of her neck. Chills of pleasure swamped her. She pressed back into his arms as he fondled her large tits and then plowed a finger down into the brown thatch of her pubes. She felt him divide the swollen lips of her cunt and search gently inside for the clit that she wanted him to find.

He moved so that she was sitting in the circle of his legs, her back against his stomach as he felt her pussy, searched each hot and slippery fold, dug a thumb upward into her cunt until she whimpered and let her head fall backward. She could feel his huge cock pressed up against her ass and back. She pushed her legs out straight in the sleeper. His hands worked like hungry animals at her parted pussy. She saw the dark circle her juice was making on the sheet.

"I might hate myself for all this, Marcia." Nat kissed her shoulder. "But it's as good as done now. I'm going to fuck you, honey. I'm gonna fuck you good as I know how to fuck. I just hope you don't hate me and hate yourself after it's all over with."

"Oh God, Nat! I'd die for you! I love you!"

He smothered her mouth with his and let his middle finger slide into the valley between her cuntlips, let it slide under and up until she felt it rubbing against the silken walls of her pussy.

Marcia moaned into his mouth and squirmed wildly. No man had ever held her like this. His embrace felt secure and lovely and right. And then Nat was pulling her up higher as he lay back. She could feel his cock sliding down under her ass, further even until she sat on his abdomen, his knees supporting part of her weight. The tip of his cock jutted back toward the glistening split of her pussy. Nat was lying on his back now as she sat there erect, touching the heavy cock that grew from his crotch.

"Nat… I… Ohhhh God, I'm about to burn up!"

She fumbled at the huge cock and as she did, the foreskin slipped back to expose the tumid glans. She was looking at it. The tendons in her thighs tingled with excitement. She inched her ass down on Nat's belly. With shaking fingers she guided the bulging, thick tip against her cunt-hole.

"Uhhhh… Oh Jesus! Oh Nat, how will I get it in?"

Nat smoothed her back with warm fingers, then circled her waist and lifted her slightly.

"Lean back a little and scoot down with your knees… it'll go in baby, it'll go…"

"Ohhhh, I'm scared… your cock's so hot and hard!"

Still supporting herself on her knees, she lifted her body so that her cunt was directly under Nat's prick. He helped her hold it at the right angle as she lowered herself carefully. She was gasping more than breathing.

When the hot, streamlined tip of his prick pressed at her slit she saw her cuntlips force back the foreskin to expose the purple ridge where the glans flared from the shaft. It was scary and gorgeous too. The hot meat slipped into the soft hole of her cunt. Instinctively she closed her muscles down, barring entrance.

Nat grunted as the powerful circle of her pussy caressed his cockhead. Then he tightened his grip on Marcia's waist and forced her slowly down. The ring gave, parted for the slick tip of his prick.

Marcia was panting hard. She rocked her hips, pulling upwards, afraid. But Nat's hands kept a steady pressure downwards. As she squirmed nervously, she felt the mouth of her pussy stretched and then stretched more. Just when it seemed like something would break, Nat move his hips and the glans entered her, popped past the muscled lips of her cunt.

"Ohhh noooo! You're too big… Oh Nat, I can't think straight anymore… I love you, Nat… Ohhhhh what's happening to me?"

She sank back helplessly on his chest. It was a strange and exciting position. Nat on his back, legs spread… she with her back against his chest as she covered the hands that loved her tits. His cock was inside her cunt now. When she moved, his prick felt like he could tear her pussy out. She was deathly afraid of his cock and crazy about it too.

She brought her knees together and bent them until her heels dragged up the mattress and nestled against the wrinkled warmth of Nat's big balls.

"I love the way your ass fits against me," he said, voice raw with excitement. "You're some kind of woman, Marcia." He bumped his hips and she felt another inch of cock fuck into her cunt.

"Ohhhhh!"

The sensations that tingled through her stretched pussy were indescribable. She let her hands flutter down over her belly, down beneath the soft curve of her cunt. And there she felt his cock. She traced the steel-hard shaft where it entered her pussy. Her outer lips were peeled back around its massive thickness and floods of cuntjuice poured from the delicate membranes. Her glands were trying to lubricate her cunt for the invasion of something so large.
