Mel Marshall: Two-way sisters

"Oh, Dave, fuck me. Fuck me from behind!" Her wiggling ass was stuck up in the air, and he saw her from the side. Paul was stretched out on the couch lengthwise, his prick wet with Dianne's saliva.

"What a whore you are. You didn't even give him time to get out of his clothes!"

It was true – Paul was still fully clothed, and Dianne had only taken time to release his upthrusting cock from the zipper. She gave no reply, for her mouth was crammed full again.

Reluctantly Dave disentangled himself from Bobbi. He wanted to fuck Dianne like that while she sucked off Paul. In a flash, he was out of his clothing and positioning himself behind the arm of the couch, his knees pressing against it. He had moved his wife's legs apart so that they stuck out on either side of his thighs. He placed his palms on the half-moons of her ass and teasingly let his cock slide against her crack. He made no move to put it inside. Her hips thrust back jerkily, trying to spear herself on his hard prong. But each thrust only sent his prick slithering along her cuntal deft to rub against her belly. She began to grunt in frustration.

"Do you want it?" he asked. "Tell me how much you want it!"

Her mouth pulled up off Paul's knob, and he groaned. "Oh, yes, honey, I want it! I've got to have your big cock in me!"

But he was in no hurry. He wanted to drive her out of her mind, to prolong the sweet agony as long as possible. When she sank back down on their guest, he used his thumbs to part the down-hanging pussy lips. They opened wetly to his touch, and she thrust her ass up to him as high as she could, her crack opening even further to show her tense asshole.

Paul groaned again as her sucking mouth slid up over his glans. It was good, so good!

"Sis," Dianne panted. "Show me your cunt!"

Bobbi had been totally absorbed in the tableau before her. She was reluctant to switch from being an observer to a participant. The landlord's presence made her feel funny, a little embarrassed. But she was beginning to feel excited, too. Besides, his eyes were tightly closed. He was totally lost in the oral pleasure, and his hips were bumping up, trying to find the warm sanctuary of Dianne's mouth. It would be such fun to expose herself like that to all of them!

She slouched down, placed her bare feet on the edge of the cushion, and flipped her dress onto her stomach, her heels against her butt. She felt the air on her muff. She also saw two pairs of excited eyes on her.

"Now open it up wide so we can see everything!" Dianne said.

"Yeah, open wide!" Dave added. "Play with yourself!"

Bobbi saw that Mr. Giddings had turned his head and was also watching. Again she felt reluctant. It was so nasty, showing her curd like this while they fucked each other. But why not? Her reluctance turned to obscene pleasure. She took a perverse delight in spreading her pussy apart with her hands. She hunched down a little further and spread her legs as far apart as they would go.

"Jesus!" Dave exclaimed. "You've got the prettiest cunt!"

"Honey, if you were over here I'd suck it for you," Dianne asked.

But she did not want to join the three people. Instead, she toyed with her girly prick, moving her hand away occasionally so they could get a good view. She dipped her finger into her cunny and spread the juice around the growing button.

"Suck me, suck me!" Paul said desperately. His hands pushed Dianne's head back down on his cock.

Bobbi's pussy was aching as she rubbed her downy cleft. Her clit was standing up straight and proud. It was exciting to watch Dave and Dianne, and it was even better yet to see her sister getting off with two men. Even if one of those men was Mr. Giddings. She could hardly believe the size of his prick – it was even bigger than Dave's! If he tried to put it in her, it would probably split her in two!

Dave figured he had let the delicious torment go on long enough. He feathered his dick into the woman, holding her ass still as he eased his glans past the tight constriction of her cunt entrance. The angle of entry was different from the missionary position – he felt more pressure on the underside of his shaft as it slid over her hard pubic bone.

Now it was his turn for frustration. The arm of the couch was in his way, and his cock would only penetrate her for about half its length. He could go forward only so far, no further. But by using his hands, he could move her back against him. Her sheath gripped him tighter as he rocked her backward until her buttocks slapped against his stomach. Then forward again, and back. It was incredible! This way he could brace himself against the couch and he didn't even have to move his hips! He was fucking her just by rocking her back and forth!

She made a guttural sound as his stiff cock entered her completely. She felt him clear to her stomach! The rocking made it harder to keep the tool in her mouth, but she had a way to deal with that. She made a tight "O" with her lips, stiffening them as much as she could to insulate the tender prick skin from her teeth. With the back-and-forth motion, it was just like he was fucking her mouth, while she got it from behind at the same time!

Paul had not been able to go as deep in her throat as he liked, but the soft, flicking tongue on his cock was better in a lot of ways. The idea wasn't as exciting, but it would bring him off a lot sooner. When he felt her lips clamp around his dick, he loved it. The boiling sperm in his balls was close to breaking through. And when she began to move her mouth on his shaft, there was no holding back. It gushed from him like lava from a volcano.

The salty, somewhat bitter taste spurred her own orgasm. She had not liked the taste of a man's cum the first few times she tried it, but she flew to like it more each time she had it in her mouth. I tasted different with different men at different times, she didn't know why. She tried to get every drop – she loved to swallow the warm, slippery emission. But she jerked with such frenzy at her own delicious release that the thick pecker came out of her mouth. She jammed herself back on her husband's prick, and she felt the flashes shoot through her cunt, her clit, up to her breasts, and all along her ass! She squealed.

Bobbi began rubbing her clit frantically as she saw the signs of two people getting their rocks off at once. Drops of white cream came from her sister's contorted mouth and a few lit in the thick tangle of Mr. Giddings' dark pubic hair. Her own thrills quickened at the sight of the big cock and her sister's sweet cry of ecstasy.

Dave was the only one of the group who felt any sort of disappointment, for Dianne had slid off his cock and lay in a quivering, coming heap on top of Paul. Having to leave the warm confines of her deliciously grasping cunt was like plunging outdoors in the dead of winter.

She rose and began to unfasten all the buttons of the clothing of the man lying below her. "God, that was fine!"

"You'd better be careful or you're going to wear yourself out!" Dave said.

"Don't worry, hon, there's plenty more where that came from."

"Yeah, but what about me?" Dave's cock still ached to be inside the woman.

"Oh, poor baby! I've been neglecting you." She turned and he saw the jutting hills of her titties with their rosy-tipped points. Her mouth encased his rod as she cupped his balls with one hand. The renewed warm wetness made him groan at its goodness.

Meanwhile, Paul completed the unfinished job of removing his clothing. He had been eyeing Bobbi as her hand moved over her wet slit. God he would love to get his cock into her sweet, young cunt! He couldn't imagine liar showing her charms like she was doing now a few days ago. She had changed. And maybe other things had changed, too.

"Bobbi," he called. "Can I come over there with you?"
