Dressed for sex

Donna unzipped Kathleen’s dress right down the front.
"Get your hands off her tits," Kathleen moaned.

Martin did, slowly. He skimmed along the wet plane of Donna’s midriff down to the skirt of her toga. He undid the belt and dragged it off her. It wasn’t simple; the skirt hugged her voluptuous body, but he eventually persuaded it down her long athletic legs. She wore no panties. Had someone removed them earlier or did she just go out like that, inviting lovers?

"Uhhhhhunnnhhhh ohhhh fuuuck!" grunted Donna. Martin was slipping the head of his cock around the opening of her juicy vulva.
"He’s not going anywhere, honey," Donna gasped. "He’s staying right here, inside me."

Martin pushed forward, sinking his rock-hard penis into her. He gasped at the way her vagina lovingly sucked at his dick. It was warm and ravenous. He slid in and out, feeding it with his throbbing organ. Donna lifted her hips with the movement.

Kathleen couldn’t bear it any longer. She struggled out of her dress. Wearing only a white satin bra, she lay under Donna. She clasped Donna’s hips fast between her knees and pumped her up and down on her son’s penis.

Martin gazed at Kathleen’s pretty face. Her brow was furrowed in concentration. Her dark eyes were wide and savage. Her lips were open. She was making little guttural noises below her breath. He looked deep into her eyes.

It was as if he was fucking his mother. But they had wet wild whooping Donna between them.
And she was coming! Donna was grabbing hold of Kathleen’s messy raven hair and screaming.
"EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!"

Kathleen kissed Donna hard on the lips, cutting off the scream but getting all that explosive pleasure through her shuddering body and darting tongue. They all felt her orgasm. She almost shook her lovers off.

Martin came inside the blonde goddess. 
"Uhhhhhhhhhhhhhhhh!!!!!!!!"
He rolled off her, exhausted. Donna rolled the other way. The three of them lay side by side on the staircase. For a while they said nothing, just catching their breath. Martin watched their breasts rise and fall.

"I’d love to see one of you on top of the other," Donna said.
"I bet you would," laughed Kathleen. "It’s not going to happen."
Martin could feel his dick hardening again. Again…!
"I’d love to see you suck him off."

"You do it," Martin’s mother snapped. She didn't want Martin there anyway. But then... "I’ll watch."
Donna grinned over at Martin and crawled down his aching body. She enveloped him, slapping his sweaty flesh against her sweaty flesh. When she took his stiff dick into the kiss of her lips, he was ready. On a hair trigger. It took seconds. There was less this time. His balls could harvest only so much.

Donna smiled at him with her mouth shut and then she crept all the way up Kathleen. Her tits dragged over Kathleen’s satin bra, her nipples brushing the thrusting shape of Kathleen’s nipples. She kissed Kathleen full on the mouth.

Martin saw his mother’s eyes go wide. She tried to pull her lips away but Donna held onto the back of her head. Soon she stopped fighting and moved comfortably into the tongue wrestling. Martin realised what Donna had done.

She had carried a mouthful of his sticky cum and smuggled it by a kiss into his mother’s mouth. They broke their embrace.
"Did you swallow?" Donna panted.
"Yes."
"So Martin, I want to see you on top of her. What would be the difference?"

Kathleen looked at her son. She involuntarily licked her lips. She didn't mean him to but he took the message. He bent his head and sucked at one of his mother’s nipples through her bra. Donna took his lead. She suckled the other one.

Kathleen lay back and accepted it. She was trapped in the ecstacy of the moment. She had never felt this aroused. She had never felt so sensual.
Martin slipped her bra down, off the swell of his mother’s breasts. They were a little larger than Donna’s. Ripe and proud. 
"Suck them, please!"
That voice had been his mother’s, harsh and urgent.
Donna had her tongue back between his mother’s legs.

He played with her stunning globes, feeling each wave of pleasure as she squirmed in his mouth. His tongue was furtive and guilty at first, not believing what he was doing. Sucking his mother’s tits. Not as a child feeding, but as an adult, sexually gratifying her. Making her cum. He climbed on top of her and straddled her stomach.

With his knees on either side of her, he pushed her breasts together. He lunged forward and forced his penis between her slippery melons. He pushed his dick in and out of the carnal valley between them, lubricated by a delicious sheen of sweat on her. The fast pummelling of her bust had its own toe-curling effect on her. She shrieked with delight. She threw back her head. Her mouth made a pleasurable O.

He ejaculated copiously, spilling his seed all over her naked heaving tits. Drops flew from his steaming head onto her chin and neck. Finally she grappled hold of the thick length of her son’s penis and tugged at it. 

This was the moment when she forgot who Martin was. She was drunk on a double hedonism of wine and physical sexual pleasure. 
She moved her head forward and she caught a gloop of his erotic juice in her mouth. She swallowed and went immediately down on him. 

Donna joined her. The two women French kissed over the pulsating purple head of his cock. Donna licked the shaft. His mother circled his helmet with her tongue.
Martin had been pushed onto his back by his mother’s insistent blow-job. Both women approached him from the lower stairs. They lay, side-by-side, lapping at his crotch.

The two women still couldn’t keep their hands off each other. Both of them jerked at his dick with their dumb hand – it gave him a weird sensation of being fought over, dragged from one mouth to the other. That left them each their smart hand. Donna tickled Kathleen’s clitoris, drawing choking noises from her. Kathleen had two of her fingers deep in Donna’s cunt, delving into her, then circling that sensitive spot just inside.

They half-turned, facing one another. Kathleen swept one of her tanned legs across Donna’s paler ones. She crushed her chest against Donna’s. Their breasts heaved against each other as though they were piglets fighting for space.

"Oh yuk!" said Kathleen.
Martin hadn't cum. He didn't have anything left. But his dick was sticky and it had splashed cock-spittle all over his mother’s pretty face. She laughed and licked at it. Donna lapped it up off the other woman’s lips.

It was easy for Martin to shuffle down a few stairs around his mother’s back. The two women were licking at each other’s faces like they tasted of chocolate. He groped his mother’s crotch, finding the little organ. With his other hand he fondled Donna’s ass. They kissed all the while. Their kissing got heavier when he stuffed his penis up inside his mother.

It went in sweetly, as though it belonged there. The fit was like a luxuriant velvet sheath, perfect for his size and shape. She moaned against Donna’s lips.
For the first half hour he made love to his mother smoothly and slowly. It was like pumping water, except that every time he moved inside her she cried with pleasure. Her flowing juices coated his cock, making his passage into her greasy and effortless. Donna let him control the pace and fed her tongue into Kathleen’s mouth to accentuate her purrs and fuck-words.

Then, Martin became fiercer. He picked up speed. He ground himself into her back, clambering onto her bopping ass. He wanted to fuck her like an animal. A beautiful mythical beast, but still an animal. 

Kathleen responded with the right attitude. She got herself up on all fours, her fingers digging into the carpet. She swung her hips down then back up, squealing when he entered her again and again.

Donna was startled at the precision Martin showed. He was thrusting from so far away that his penis left her body each time. It slurped out of Kathleen’s wet cunt, streaming a trail of juices, then he’d plunge it back in again. His aim was impressive. Right out, then right back in. Kathleen was going bat-shit under his onslaught. She was screaming.
"Fuck! Fuck! Fuck! Fuck meeeeee!"

Donna disentangled herself and sat on the stairs watching. She was a stunning woman. But she wasn’t going to get fucked by either of these two right now. They were a long way into each other’s twisting pulsing desires. All she could do was watch. And get herself off…

Mother and son both came together. Martin felt himself dry-shooting while he was deep inside her. She felt it too and pushed her ass up into his crotch. He grasped a tit in each hand and anchored himself inside her. He shuddered, his belly sticking to the small of her back. She orgasmed, shaking like an earthquake. Her knees gave way and they collapsed. Her beneath him.

He gave a few more feeble thrusts but it was all he had.
After a while, Donna pulled Martin off her. It was like finding survivors after a major disaster.
“I came too,” Donna said. “And I was just watching.”
"Why don't we all go to bed?" invited Kathleen.

Donna became a firm family friend after that. The three of them would go to the movies together or meet up for a quick drink after work. And every so often, Martin would wait in his room for Donna and Kathleen to dress up.

And they would play on the stairs.
