Sally Simpson - And mom makes three

"Yes!" Sally screamed as a shattering orgasm sliced through her body. She slid down the wall, scraping her tits, belly and thighs against it as she collapsed in a heap onto the floor.

She was weak from all the orgasms she had had. Her ears were ringing, and the room was out of focus. She could hear her own rasping breaths, feel her heart pounding in her chest.

And then she heard something else. At first, she thought it was her imagination – a slight shuffling of feet; a muffled giggle. She closed her eyes and tried to slow her breathing and ease the ringing in her ears. But she heard the giggling again.

Goose bumps climbed up her back. She reached for her blouse and held it against her tits, and then slowly, slowly, she turned to look behind her.

Her little son and daughter were standing near the door, staring at her, lewd smiles on their faces.

Sally poured herself a cup of tea. She had been feeling shaky since yesterday afternoon, when the children had discovered her in Room 120, spying on the couple next door while she finger-fucked herself.

She had ordered them to leave the room and to wait in the motel office. Then she'd somehow managed to fumble back into her clothes and go out to meet them. They had been whispering to each other when she walked in, and it had made her very nervous.

She wasn't sure just how much they'd seen, but she told the kids that she'd been exercising in the nude, as her doctor had prescribed, and that it had been very naughty of them to spy on her.

Billy simply rolled his eyes and dug his elbows into little Cindy's ribs, and that had made Sally furious.

"I guess you don't understand the seriousness of what you did!" she had sputtered. "Go to your rooms. No dinner for either of you tonight!"

All had been quiet at breakfast the next morning, but Sally could feel the children staring at her whenever she turned her back to them. What really ate at her was the thought that they might tell Jack what they'd seen when he got back from the motel owners' convention tomorrow. And if they did tell him, would he believe them?

She shuddered at the thought, nearly spilling the tea. Quickly, she put the cup to her lips and took a sip of the soothing brew.

At that moment, Billy walked into the kitchen. He was dressed in a T-shirt and last year's cut-offs, and Sally realized that he'd grown a good four inches since the year before; the cut-offs were way too short.

"About yesterday afternoon, Billy," she blurted.

"Yeah," Billy said, a smile crossing his face. "You sure do have a beautiful body, Mom!" He came closer, put a hand on her shoulder, then leaned down and kissed her cheek.

Sally was so shocked, she couldn't say a word.

"Yup, those girls in Daddy's Playboy don't even come close to you, Mom."

"Billy! Shame on you!"

Billy kept smiling. He grabbed Sally's hand, and before she knew what was happening, he put it on the crotch of his shorts. She could feel his cock beneath the rough denim – hard and throbbing.

"Young man – what do you think you're doing?"

"Take off your clothes, Mom," he rasped, eyeing her up and down.

"How dare you talk to your mother that way! You're just a boy!" She tried to yank her hand out of his, but he held it tightly over his prick.

"If I let go, promise to take your clothes off."

"Billy, when your father gets home…"

"When my father gets home, I could tell him that you have a two-way mirror in Room 122!"

"Billy!"

"All I want you to do is take your clothes off for me again, Mom."

Sally was shaking with rage. But she knew she had no alternative. Tears came to her eyes as she nodded to her son.

He let go of her hand, then, crossing his arms over his chest, stood back, waiting for her to begin.

Sally sat there for several moments, gazing into Billy's eyes, trying to get him to take pity on her, but he stood firm. He was even bold enough to start rubbing his prick through his pants.

"Take your clothes off, Mom – or I tell Dad about yesterday!"

Tears of shame and anger sprang to Sally's eyes as she unbuttoned her dress and stepped out of it. All she had on underneath were a lacy bra and panties.

Billy's eyes bugged out, and he started rubbing his cock bulge harder. "Come on, Mom – take 'em off!"

"Please, Son…"

But Billy flashed her a look of such anger and need, she knew she'd have to go through with it. Gulping back the tears, she reached behind her and unhooked her bra. Then she brought it down her arms and off her tits.

She heard him gasp, then moan with desire. But she couldn't look at him. She just stared at the floor. Now she peeled her panties down and off her legs.

"Aw, yeah!" Billy moaned.

Sally heard the rasp of his zipper, and though she still couldn't look at him, she knew he'd taken off his clothes.

Now he walked up to her, and she raised her head to look at him. He was long-legged and thin and hadn't yet begun to fill out. And his cock was long and thin too, with a tuft of auburn hair at the base.

She shuddered with a weird combination of fear and excitement. And then he reached up and put his hands on her tits.

"God, Mom! They feel so good!" he gasped. He sank his fingers deep into her tit-flesh and squeezed hard. "Mom! Mom!"

Suddenly, his prick erupted with a hot stream of jizz that splattered onto Sally's belly and thighs.

"God, Billy! How could you?" Sally sobbed, and she tried to back away from him.

But he held onto her, pressed his mouth to her left tit and began sucking hard-on the nipple.

A sudden thrill of pleasure shot from her tit down to her cunt. Without thinking, she put her hand on the back of his head and began pressing against it, forcing him harder against her tit.

He moaned as he sucked and licked her nipple, his other hand clawing frantically at her right tit. He was so close, that Sally could feel his cock get stiff again and nudge her thigh.

Suddenly, Billy pulled away from her and looked up into her eyes. "I want to fuck you! Let me fuck you, Mom!"

Though his words shocked Sally, she knew that that was what she really wanted, too. Her cunt was churning inside with need; her body was on fire with desire. And who would ever know if she fucked him, except Billy and her?

"Yes, baby, yes!" she whispered. "Into the bedroom – hurry!"

She grabbed Billy's hand and practically dragged him down the hall to her bedroom. She could never remember being as excited as she was at this moment. Hot, slick cunt juice was pumping from deep in her fuck hole; her tits tingled with arousal; she could still feel where the boy had had his mouth on her tit.

She lay back on the bed and motioned for Billy to join her. She had no idea how much he knew about fucking – whether he was still a virgin or not. All she cared about was feeling his hot young cock slammed up her pussy.

"Billy, honey, come to me," she gasped as she reached for him. At the same time, she spread her thighs, revealing her cunt to the boy.

Billy was breathing hard as he climbed onto the bed. Gingerly, he reached out to his mother's pussy and combed his fingers through the dense, curly hair above it.

"Yes, Billy, yes!" Sally moaned, rocking from side to side.

Now Billy slid his finger up and down his mother's wet cunt slot, and she quivered with excitement. Spreading the fleshy lips of her pussy apart, he jabbed his index finger up her fuck hole.

"Oh – Billy!"

He licked his lips and grabbed his prick at the root, aiming it so the knob tit into the entrance to Sally's cunt.

"Ah-ah-ah, Billy!"

Sally couldn't stand the excitement any longer. She humped forward, trying to capture the boy's prick head in her pussy, and at the same moment, Billy thrust into her hard.
