Betsy watched her father slam his prick into Lisa's cunt while she licked Mark's cock hungrily.
"Keep sucking," Mark said, his eyes glued to his mother's gyrating hips and ass.
"Keep fucking me like that," Lisa said. "I'm going to come now."
Ted stepped up the tempo of his thrusting. Betsy felt dizzy and faint. She took as much of Mark's cock into her mouth as she could without gagging and watched her father bang away at her aunt's cunt.
Shaking violently, Lisa gyrated her ass as she climaxed. Hovering above her, Ted pumped his cock into her as he came.
"That was the best one yet," Lisa gasped after a few moments.
"Shut up and suck," Ted said, pushing her down on her back and shoving his limp cock into her mouth.
CHAPTER SIX
A week later Mona insisted, that Betsy go shopping with her after school. The men were at work and Lisa sat alone in her bedroom, still dressed in a sheer robe at three in the afternoon.
As she filed her fingernails she thought about how horny she was. She sighed. She was fucking three men regularly. First there was her husband, then her father-in-law and brother-in-law. But it wasn't enough. Her sexual needs were getting out of hand and she didn't know what to do about it.
When she glanced up, she saw Mark in the yard staring in at her. She saw at once by the look on his face that her half-dressed body was exciting him.
My God, he's growing up so fast, she thought.
"What are you doing, darling?" she called out.
"Just hanging out, Mom," he said.
"Come on up and keep me company. I'm alone too."
The words were out before she had a chance to examine her innermost motives. The teenager hesitated for a long moment. Then he nodded and bounded into the house.
The horny mother instinctively tied her sheer robe more tightly around her curves. He's my son, she thought. What does it matter if he sees a little cleavage?
She tried not to think about the way he looked at her lately. But when he entered her room, it thrilled her to see the look of admiration on his face.
"How come you're not out with your friends?" she said, continuing to file her nails.
He flopped down onto the bed. "I thought I'd just hang around the house."
She tried to stop the beating of her heart, but the way Mark was staring at her tits made her feel undressed.
They chatted casually. Lisa tried to steer the conversation around to school and sports. She'd been horny all morning and if Mark wasn't around she would probably be jerking off by now.
As they talked she couldn't help but wonder how her son would be in bed. He was almost a man and considering the bulge in the front of his jeans he was probably a horny kid.
It seemed so strange to be examining her own child this way. She had given birth to him many years ago. She had pushed him through her birth canal and nursed him. Now as she gazed at his lean young body she thought it would be a kick to fuck him.
Once she realized the idea appealed to her she became calmer. Her pussy moistened at the prospect of having her own child's cock up her pussy. She salivated when she imagined taking his cock into her mouth.
Mark was rambling on about the football team, but his eyes were focused on her tits. Lisa finished her nails and began brushing her hair.
"Darling, you've been staring at me like mad," she smiled.
He reddened. "I have?"
Tossing the hairbrush down, she swirled around on the chair and faced him. "Yes, you have, and you're making me self-conscious." Giggling, she glanced down at her half-exposed boobs. "You've seen me like this before. They're just tits."
"Aw, Mom," he blushed, punching a pillow and remembering how she'd looked being fucked by his uncle.
The horny mother crossed her legs, aware that she was showing the boy a lot of thigh.
"Do you think I'm pretty, darling?"
His voice was tight and he averted his eyes.
"I think you're beautiful."
An almost electric surge of excitement raged through her.
"Would you like to see all of me?"
The boy stared at her, his eyes dark and limpid. "Are you kidding, Mom?"
Lisa's heart pounded. She crossed and uncrossed her legs. Almost defiantly she rose up and untied her robe.
"Why shouldn't you get a good look at my tits? They're pretty. I've nothing to hide."
She pulled her shoulders back and thrust her tits out. Her firm, big-nippled tits jiggled slightly and the teenager's eyes widened.
"Jesus, Mom!" he breathed.
"I nursed you with these tits," she said more calmly. "There's no reason to hide them now." She glanced down at her chest, pleased with what she saw. "Do you think they're pretty?"
"Jesus, Mom, you've got the best pair I ever saw."
The hot-blooded mother was fully aware of the hard-on he had in his jeans. She could hardly keep her eyes off his crotch. Now she stood next to the bed with her robe open, her pussy hidden by her panties.
She sat down next to the boy and took his hand. "When you were little and nursing you used to squeeze my tits like crazy. I don't suppose you remember, but your dad and I used to laugh and say you'd be a tit-man when you grew up." She leaned over, patting his chest and belly lightly. "Are you a tit-man, darling, now that you're almost a man?"
He cleared his throat nervously. "I guess so."
"I love having my tits played with, Son," she whispered. "I really love it."
He gulped. "You do?"
"I do, darling," she smiled, guiding his hand toward her tit.
"Jesus, Mom…"
She let out a soft sigh when his fingers touched her tits. A tremor surged through he pussy. She was hornier than she realized.
"Oh, darling, that feels so good," she said when his confidence increased and he gently moved both hands over her tits.
When he touched her nipples, she gasped. They hardened at once and when she met Mark's eyes she beamed.
"See how excited you're making me?" she said.
"Jesus, Mom, I can't believe you're letting me do this."
"You mustn't ever tell anyone," she said, covering his hands with hers. "Oh, darling, I'm so excited now that you're touching me. Kiss them, sweetheart. Kiss mother's tits, she wants it so much."
He flushed crimson and continued squeezing her tits.
"Now?" he croaked.
She nodded, half-dazed with excitement.
"Yes, now!" she hissed.
When his lips made contact with her tits, her pussy spasmed wetly.
"Oh, baby, you're making me so wet."
She trembled when he extended his tongue and lapped it over her nipples. He held her tits in both hands. She cradled his head as she had when he nursed on her tits only now there was no milk. Now as he sucked her stiff nipples into his mouth she had a mild climax.
"Darling, you just made me come," she giggled.
He smacked his lips over her tits, apparently unwilling to release them long enough to respond to her words. But a look of pride and confidence crossed his face. In that moment the incestuous mother knew he would be a wonderful lover.
"Keep sucking," she said, stroking the back of his head and holding his mouth firmly against her full tits. "My darling baby boy is still a tit-man."
He moved from one tit to the other. The longer he sucked the more excited Lisa became.
"You're perspiring, honey," she said. "Why don't you take your tee-shirt off?"
When he pulled his shirt off, she pushed him down on his back and began stroking his chest. Her tits hung over his chest.
"Can I suck them again, Mom?"
"I've got something better for you."
She smiled, nibbling his nipples and guiding one of his hands between her legs. His fingers singed her already hot pussy. She clamped her legs shut around his hand and peppered his chest with kisses.
