Sally Simpson - And mom makes three

Suddenly Cindy's forehead wrinkled into a frown of such agony that Sally knew she had crossed the line, and was heading for a mind boggling orgasm.

Now Billy's groin was hitting Cindy's cunt mound directly, and the girl was crying with passion, humping up at him violently. She raised her legs off the bed, making the angle of contact even better, and Billy grabbed her legs, slipping them onto his shoulders.

Cindy threw back her head, opened her mouth and wailed. Even Sally heard the heartrending cry, and her cunt went back into gear, churning out a flood of slick pussy juice.

As Sally had always known, there was nothing quite like jacking off while watching another woman have a powerful orgasm. It made her own orgasm really powerful.

And now, as the girl twisted and squirmed beneath her brother, coming and coming, coming, Sally got off, too. One after the other, quick, satisfying orgasms rocketed through her cunt. And her clit battered from all the diddling she had given it, throbbed with a delicious mixture of pleasure and pain.

Only a moment after Sally came, she saw Billy rear back and then jam forward into Cindy. It must have been a tremendous orgasm for he shook and shuddered for nearly a minute afterwards, his ass cheeks tensing and relaxing as he emptied his cum-load.

Sally was tempted to go next door in the aftermath of the fucking, but some instinct told her to hold on for a little while longer. And she was not disappointed.

Billy raised himself off Cindy, letting his shriveled prick slide out of her pussy, trailing cunt juice after it. Then he began to stroke her hair.

From her hair, his hands moved down over her little tits. This time, he did not squeeze or knead them, but just petted them very tenderly.

Cindy responded, smiling lovingly at him, reaching up to put her hand on his and direct it over the areas she most wanted touched. She directed him down over her belly and to the soft hump of her smooth cunt mound. As if the powerful orgasm she had just experienced hadn't been enough, she pulled on Billy's second and third fingers, aiming them at her cunt.

Sally looked on, bug-eyed. The girl was tireless!

Billy began diddle her cunt but then he dropped, leaned down and whispered something to her. She gave him a shocked look, but as he continued to speak to her, a lewd smile crept across her face. At last, she nodded her head vigorously and moved over on the bed.

The next thing Sally knew, the two of them had gotten themselves into a perfect 69 position, Cindy slurping onto her brother's limp prick, and Billy tonguing her pussy.

Sally watched in disbelief. She hadn't shown either of them about 69, but they had managed to figure it out for themselves. And they were doing it like they'd done it a hundred times before.

The way Cindy was sucking and licking on her brother's prick, it was fully hard in moments. Then she launched into a cocksucking routine that rivaled the best oval of her lips over her pearly teeth, she went down on Billy's prick knob, then sucked her way halfway down the cock shaft.

Sally held her breath, wondering what the girl would do next. Surely there was no more room in her mouth for the rest of Billy's prick meat. But this problem did not seem to worry Cindy. Arching her neck, she took a deep breath and sucked his prick down into her throat, so his jism balls bounced up against her chin.

"Holy shit!" Sally gasped, her eyes wide in amazement.

The way Cindy's throat muscles were moving, Sally could tell she was running them up and down Billy's prick, massaging it like a pro.

And there was no question that Billy was enjoying it. His face was contorted with lust, and he had stopped his cunt-licking as waves of excitement washed over his slim frame.

But he pulled himself together enough to fuck his tongue into his sister's soft pussy and start pistoning it in and out in a fast, steady rhythm.

It was too much for Sally. Her cunt was throbbing with a need that her fingers couldn't possibly satisfy.

"I've got to get over there – I don't care what they say!" she groaned.

She carelessly threw on her clothes, left the room and walked next door. With her pass key, she unlocked Room 122, stepped inside and locked the door behind her.

The two teens lay panting on the bed, exhausted. As Sally came closer, she saw Billy's prick slide out of Cindy's mouth, semi-hard but shrinking rapidly. Several thick drops of cum seeped from his piss-slit, staining the bedspread.

Cindy was shocked when she saw Sally enter the room. Pulling her pussy away from Billy's face, she said: "Mom, let me explain… It was an accident."

"Don't be ridiculous!" Sally laughed. "You can hardly do 69 by accident. Anyway, I'm glad that you and Billy finally got it on." She winked at Billy, who was now sitting up on the bed, smiling slyly at her. "I'm only sorry I couldn't join in the fun."

"It's not too late," Billy said, leering at her. Sally looked at his shriveled prick. "Ain't much you can do with that, Billy!"

Billy snickered. "I'll bet that if you took off your clothes and shook that body of yours, I could get a hard-on, no sweat!"

Sally's pussy tingled with excitement. Dirty talk always did that to her. But she was interested in more than talk. She would give Billy just what he asked for – eventually.

She smiled sexily at the boy. Then she half closed her eyes and began gyrating her hips like a belly dancer. She turned in a circle, letting the children see what a sexy figure she had from the back, as well as the front.

Billy licked his lips in anticipation. Just as Sally as expected, his prick was quickly becoming hard again.

Now Sally unbuttoned her blouse, shimmy big her shoulders so the material fell away from her and drifted to the floor. Next, she undid the zipper of her shorts, peeling them down her hips and legs. When she was free of them, she pranced about the room in her bra and panties, flaunting her gorgeous figure.

"What a fox!" Cindy gasped, leaning forward, following her mother's every move.

Sally prolonged the excitement by starting to undo the front clasp of her bra and revealing a portion of her big tits. But before she had slid the bra down as far as her nipples, she stopped and covered herself up again and continued with her bumping and grinding.

"Take it off! Take it off!" Billy cried.

But Sally just smiled at him. She played the same game with her panties, hooking her fingers under the waistband and pulling it down an inch to reveal the top of her red-haired pussy mound. Then she let go of the elastic, and it snapped back into place.

"Jesus!" Billy groaned. His cock was stiff now, shaking with tension.

Sally's gaze fastened on the boy's upright cock, and she shuddered with lust. Things were progressing much faster than she'd thought they would. It was time to get down to business.

She reached up and undid her bra, slipping it off her tits and down her arms. When her big tits came into view, both children whistled.

Sally cupped her tits in her hands, raising them up and squeezing them together so that they formed a deep cleavage. Her tits were so big that when she lowered her chin, she was able to kiss the tops of them. She did this now, pressing her lips to the sweet tit-flesh, licking it till it shone with her saliva.

"Shit!" Billy groaned, jacking vigorously on his prick.

The sexy sight was too much for Cindy. She jutted her finger between her cunt labes and began to diddle her clit.

Sally let go of her tits, and they bounced back into place. But when she began wiggling her ass and hips again, her tits began to jiggle and wobble crazily.

Billy groaned with desire at the sight of all that rich, quivering tit-flesh. He began jacking so hard-on his cock that a stream of pre-cum poured from the tip.
