"Do you know what you're doing?" he said.
"Sure I do," she said. "I'm licking your asshole."
"Jesus, I just shit before."
"I don't care."
"Take my cock in your mouth again."
"Yummy," she said, hungrily sucking his cock into her moist pink lips.
"Mom was looking at the bed sort of funny."
"I never moved."
"You sure did. You were licking my cock all the time."
"Well, she didn't see me. I'm at a pajama party, remember?"
He chuckled. "Jesus, Sis, for a kid you're a wild one."
She squeezed the base of his prick and licked his balls. "For a kid you've got a neat cock."
She loved the taste of his balls. She licked them thoroughly, wetting down the hair on the underside of his ball-bag. She liked the taste and feel of his nuts. She liked when they filled up with spunk and she liked feeling the little hard things inside.
But she liked sucking his cock too much to lick his balls for long. Balls were good and assholes were delicious, but the main course was cock. She loved it.
Turning a boy on excited her. She felt a sort of power when she gave one of her brothers a hard-on. Her pussy felt wet and slimy. She squeezed her legs together tightly to savor the feeling engulfing her.
By now Jimmy's cock was rock-hard. She slid her lips up and down the shaft and used her fingers on the base. It had been very exciting when her mother walked into the room. She loved fooling Judy. She almost wanted to be caught in her brother's bed.
Now Jimmy lurched forward, sending his cock soaring into her throat. She sputtered and spit half of it out, but dug her fingers into his asscrack.
She wondered if her father cheated on her mother. Sometimes her father stared at her in a funny way. She wondered if he found her sexy. Fathers and daughters sometimes made out. She'd heard stories from her friends.
She felt herself salivating at the thought. She tugged on the little piece of skin on the underside of Jimmy's cock. He dug his fingers into her head. God, he was horny.
Still sucking his prick, she began masturbating. Her little clit was on fire. Fuck me, Daddy, eight to the bar, she thought with a giggle.
She kept sucking Jimmy's prick and masturbating, but after a while he pulled her on top of him. "Want to fuck?" she said with the innocence of a child.
"Yeah, but you can stay on top," her brother said.
"I can? You mean like this?" As she spoke she swung her leg over him, straddling his prick.
"Yeah, sit on it," he said.
Grabbing his cock, the teenager lowered her ass until her pussy touched the tip. "Now what?" she said.
"Stick it in."
Breathing rapidly, she came down hard on his cock, stuffing it into her almost-virgin twat. Both youngsters gasped as she began riding him.
Each thrust of his prick inside her brought her closer to orgasm. Leaning forward, she deliberately swung her tits over his chest.
Even though she was on top he did most of the work. He held her around the waist and thrust mightily into her eager snatch.
He was close to coming. His teeth were clenched and his eyes on his sister's bouncing tits. He felt the pressure in his balls and used every ounce of control to keep from coming.
He loved his sister and wanted her to come before he shot off. "Always make sure a woman comes before you come," his father's words were chiseled into his brain.
Penny was almost there. "You get on top now," she said, flopping over onto her back.
As quickly as his cock slipped out of her, he rammed it back in. Now he thrust forcefully and she felt his balls on her ass with every stroke.
"I'm almost there," she whispered.
Jimmy nodded encouragement. Jesus, please come, he thought.
Penny bit her lips to keep from crying out. Grimacing, but silent, she climaxed. A moment later she felt Jimmy's thick jism splatter into her pussy as his cock exploded.
Judy couldn't sleep. She tossed and turned and after a while she switched on the bedside light.
Midnight and Bob still wasn't home. Damn him, she thought as she reached for a cigarette.
She switched on the television and tried concentrating on the movie. It was no use. Jimmy had looked so adorable. He was naked under his covers. Naked and probably horny. God, how she wanted him.
Why didn't I just get in bed with him? she thought.
Because you're scared, she answered herself.
Don't be a sap. You already sucked him off once. Why not go all the way? You know you want to.
She pulled her knees back and hugged them to her chest. It was true she wanted him, but how to approach a young boy in the middle of the night? A boy who just happened to be her son?
I'm his mother, for God's sake. Isn't anything sacred?
Oh, come on, honey, a voice inside her head said, what's the difference between sucking and fucking?
But he had been sleeping when she'd sucked him off.
Give me a break, she thought. You're gonna do it eventually. Why wait?
Swallowing hard, Judy glanced at the clock. Bob wouldn't be home for hours. She didn't believe for a minute he was really working late, but she didn't much care any more. They both needed more than they were getting from each other. She reached for her slippers.
The next hour was a blur. She knocked on Jimmy's door and before he had a chance to answer she entered.
This time he didn't pretend to be sleeping. Sitting up, he smiled at his mother. "Still up, Mom," he said.
She hurried over to the bed and sat down next to him. "Honey," she said, taking his hand. "I'm feeling so lonely."
His eyes widened when she pushed his hand aside and reached under the covers. "Jesus Christ!" he hissed.
"Oh, don't be so bashful," she murmured with a smile. "Let me see it."
Jimmy opened his mouth to speak, but nothing came out. If his mother wanted to see his cock, well okay, women were funny sometimes, especially at that time of the month. But after fucking Penny his cock was limp. He was embarrassed to show his mother a soft prick.
"What's the matter, honey?" Judy said bringing her legs onto the bed and stretching out next to the teenager. "Are you frightened of something?" She brushed her lips over his cheek.
"No," he said.
"Then why not show me what you've got?"
"Jesus, Mom, I would, but I don't think… oh, shit!" He hid his face in his hands.
He just jerked off, Judy thought. Oh, damn, he just blew his wad. Aloud she said, "I just want to see it, honey." She kissed his mouth hotly. "It's been so long since you let me see it."
Suddenly he grabbed her and kissed her.
"You can do whatever you want, Mom," he said.
A thrill shot through the horny mother. She would get his prick hard again and finally get what she wanted. "Oh, yes, darling," she breathed, returning his kisses. "And I'll make you feel good, too."
He was naked under the covers. Judy slipped out of her robe and climbed over him. Spreading her legs, she enveloped him with her tits and thighs. Lowering her cunt to his prick, she rubbed up against him.
"Were you jerking off when I walked in before?" she said.
Jimmy thought of Penny and blushed. "Yeah."
Judy nuzzled his neck and thrust her beaver against his limp dick. "That's all right, baby. I feel your cock getting hard again. Oh, baby, I think I want you to fuck me!"
Jimmy winced as she tried taking his still-limp cock into her cunt. "I'll try," he croaked.
Judy was relentless. She used her cunt to arouse him. Soon his shaft stiffened and her pussy gobbled up his cockhead.
"See, I told you it'd get hard again," she said. "Now stick it in and fuck me, Son."
Jimmy thought it was strange that his mother wanted him to fuck her, but he didn't argue. If she needed fucking, he'd be happy to oblige.
