Marvin Cox - Three-way sister

She reached under and grabbed his swinging balls. Holding them in her palms, she rubbed them over her pussy crack, touching her throbbing clit. The feeling was electric, sending jolts of pleasure up and down her slit canal. Her orgasm shot upward, unable to be stopped by anything now. It blossomed slowly, then blasted into her insides. Every muscle in her body became taut, stretching to the breaking point.

"Aieeeeee!" she screamed, pursing her shitter muscles around his lunging cock.

Chad felt her shiver with another orgasm and increased his efforts. While he plowed in and out of her shitter, he thrust his hand between her legs, gouging his fist into her oozing pussy hole. Any other time it would have been but now she was completely yielding. Her cunt rim slipped up to his wrist, sucking and pulling on his arm like a mouth.

Another spasm of hot pleasure seared into Suzi's guts when she felt her entire body being violated. She fell forward, now totally exhausted, allowing her brother to sling her around like a rag doll.

"Ready for some hot cum." Chad grunted, feeling his prick swell painfully.

"I'm… I'm… ohhhh, baby sister!" Suzi could only nod her head in response. Any other time she would have begun writhing, buckling beneath him when she felt that hot splash explode in her body. But now, she was simply too weak to move. It took great effort just to breathe. She felt Chad shove the last of his thick load into her shitter with a low groan, then collapse.

"Jesus," he grunted, "I thought I'd be able to fuck all night long, but now I don't know if I'm gonna make it! I feel like someone has yanked my guts out."

"Oh, you won't have to do anything at all," Suzi said, gently pushing him off. Her energy returned as she thought about that big meaty cock of his. "I'll just suck you all night while you lay there."

She slipped her mouth around his withering shaft, trying to chew it back to life. Try as she would, however, it refused to grow. In fact, it got limper.

"You really must be tired," she whispered, sitting back on her haunches. She looked at his face, noticing that his eyes were closed. "Chad?" she asked.

"Are you asleep?"

He didn't answer, giving only a low snort. It was obvious he was done for the night. Suzi settled herself back between his legs and studied his cock. It was so big and wonderful, she thought. But then, I've only had two in my whole life.

Then she thought of Alex and sat back up.

"Good night," she whispered to Chad as she got out of bed and slipped into her robe.

She left the room and walked down the hall, pausing before she went into Alex's room. Finally, she entered, and looked around.

The room was typical of Alex. Neat, orderly lined with books. A hand-carved jade chess set was in one corner, in another, as if on display, were several models of atoms. She sat down in the one chair in the room and looked toward the bed, thinking of all the times he must have slipped between those sheets, thinking not of girls, but valences, atomic weights, theories of… whatever.

A soft noise interrupted her thoughts, like the closing of a door. Perhaps it was Alex, she thought. Chad was in no condition even to move. She pulled her knees up to her chin, her hands on her ankles and waited.

He opened the door and looked startled when he saw her. Then, as if he were alone, he began undressing. He stripped down to his shorts and pulled the covers back. Then, lying on his back, he stared at the ceiling. For Suzi, the silence was deafening. She felt compelled to speak, but something stopped her. At least he hadn't told me to get out, she thought.

"I've been thinking," he said finally. "About you… us."

"And?"

"Am I really the way you say I am?" he asked, as if still trying to convince himself of something.

"You don't have to be," she answered.

He looked over at her and studied her face for the longest time, then his lips spread in a wide grin.

"Come here," he said.

Suzi removed her robe and moved to Alex's bed. She pulled the sheet back, draping it around his ankles. For several moments she just looked at him, her body trembling with excitement as she took in each detail.

He looked like a Greek God, powerfully built, his skin as smooth as marble. Even motionless, he looked like a cat ready to pounce, every muscle defined. He was returning her gaze, his eyes filled with longing, unblinking.

"Come here," he said, his voice just above a whisper. "Show me how to love you."

She lay beside him, placing her right hand on the inside of his thigh, the other stretched over his well-developed chest.

"My God, you're beautiful," he whispered, his eyes devouring her luscious form. He touched her tits, swirling his fingertips over the taut, rubbery nipples. "I never realized before just how beautiful you are."

He rolled to his side, studying her more carefully, as if memorizing each plane, each soft angle. He moved his hand down to her stomach until the heel of his palm slipped into the dark, silky patch of cunt hair. Leaning over, he pressed his mouth on hers, inching his hand further down to cup her firm mound of cunt. As he thrust his tongue between her teeth, he dug his middle finger into her slit.

"Oh, Alex!" Suzi murmured, feeling her insides become buttery. "Let me show you how good this can be."

She pushed him to his back and squeezed between his legs, spreading them wider with her hands. Lowering her face, she pressed her lips to the underside of his cockhead, then bared her teeth. Gently, she pulled the loose skin back, inhaling the delicious musky aroma of dried piss and cum. She held the skin with her fingers, keeping the space open, and darted the tip of her tongue inside, lapping around the small indentation. The end of his prick reacted to her touch by ballooning, glistening a dark purple.

"Are… are you going to put it in your mouth?" he asked, his voice cracking.

Answering with action rather than words, she encircled his huge cockhead with her lips and slowly sank her mouth down to the full, meaty base. When her nose brushed into his crotch hairs, she pursed her lips tightly, then pulled upward, running her tongue around the shaft.

"Jesus, how do you do that?" he asked, clearly amazed that, such a small mouth could possibly take all he had to offer. "Where are you putting it, anyway?"

"In my throat," she answered from the corner of her mouth. She gulped the entire length down once more. This time she pulled up more quickly. "Do you like it?" she asked.

"Damn, it's the best feeling I've ever had… except maybe earlier when it was in your pussy."

"I'm going to suck you as best as I can, Alex," she said, holding his cock with both hands, her mouth just a fraction of an inch from the ball of his cock, "and I want you to cum in my mouth. I'm going to suck you dry."

"Go… ahead," he murmured, bending his knees. He placed his hands behind her head, forcing her mouth back down on his prick. "Suck it, Suzi. Suck it all night long!"

Suzi gobbled down his dick now with more urgency, until her head was bobbing up and down, her forehead slapping against his stomach. She knew be must really be enjoying it because his knees were squeezing her shoulders as if she were in a vise. She could hear his soft moans, feel his breath on the top of her head. She cupped his balls and milked them, pulling them apart, rolling them over her cheeks.

"Fuck, that's good!" he grunted, half-sitting, exerting more pressure on the back of her head. "Goddamn, little sister, suck just like that… unhhhhh… Jesus, you know how to do it!" He felt his nuts about to explode, his rumbling wad of sperm already squeezing into the base of his prod. "I'm… I'm… getting close," he gasped. "Fuck, suck it, you little cocksucker, suck it!"
