Laurie slipped a hand to her pussy and rubbed her cunt as her brother pistoned his cock in and out of her wet cunt.
"My ass," she hissed. "Put your finger in my ass."
Jerry found her tight bunghole with a fingertip, slipped the finger inside and stroked her shitter as he continued fucking.
The combined stimulation of her asshole and cunthole soon carried the teenage girl into a convulsive orgasm.
She came hard, cuntjuice gushing over her brother's sliding prick, her fingers working furiously on her clit, her asshole clamping down on Jerry's fingertip.
As her spasms caused her cunt to rhythmically grip his cock, Jerry heaved and groaned and emptied his balls into her steaming pussy.
Brother and sister, lay on the bed recuperating. Laurie mused about the loss of her virginity. It seemed fitting that her brother had been the one to take her cherry. Now she was a woman.
Leaving the bed, Laurie went to the bathroom and washed her pussy. There was much less of a mess than she'd expected. She dried and powdered her cunt, and soon the touch of her fingers had her excited again.
Returning to the bedroom with a damp towel, she cleaned Jerry's cock and then slipped it into her mouth.
"Oh, Christ, not again," the boy groaned. Her mouth stuffed with his prick, Laurie gave him no reply and continued sucking.
After a while she pulled her mouth off his cock and said, "I think Mom is making it with Uncle Charlie."
Jerry looked at her with astonished eyes. "Oh, Jesus, are you sure?"
Laurie explained her suspicions to him. She said she was convinced their mother and uncle were fucking. "Why not?" she said. "They're brother and sister. We're brother and sister and we do it. Anyway, it turns me on to think about it. I really dig Uncle Charlie."
"I'm not surprised at that," Jerry smirked.
"Maybe we can watch them."
"What do you mean?"
"Well, the next time they're going to be alone in the house we'll just sneak back from wherever we are and maybe we'll be able to see it. Would you like that? Would you like to see Mom fucking Uncle Charlie?"
Jerry grinned. "You're damn right I would. And so would you. But I suspect we'll never get the chance."
Jerry was wrong. Their chance came sooner than expected. Less than a week later, on a Sunday, it happened that everyone planned to be out of the house in the afternoon except their mother and Uncle Charlie. Laurie and Jerry were supposed to be attending a double bill at a downtown movie. Instead, they returned to the house after thirty minutes and quietly crept on the veranda to the windows of the living room.
Sure enough, their mother and Uncle Charlie were doing more than just talking to each other. Their mother, in fact, was not talking at all. She had her mouth filled with Uncle Charlie's cock.
Charlie sat on the sofa with his hard, cock sticking out of his fly. Ann knelt between his legs with her mouth moving up and down the veined cylinder of his thick cockshaft.
Ann's dress was pulled up to her waist so that the teenagers could clearly see her luscious ass.
Their mother wore a garter belt and stockings, the same garter belt that Laurie had worn the day she lost her virginity.
The front of Ann's dress was open down to her waist and the heavy globes of her tits hung down and swayed as she moved.
Laurie found the sight of her mother half undressed and sucking her uncle's cock incredibly erotic. Charlie's cock looked huge. Laurie hadn't seen his cockhead yet, but she guessed his knob must be the size of her fist.
Ann now happened to turn her body so that her ass faced the windows. The two teenagers suddenly had a wonderful view of their mother's cunt and ass from the rear.
Laurie's breathing was ragged as she gazed at her mother's pinkish-brown asshole and hairless thick cuntlips. My God, she shaves her pussy! Laurie thought. The teenage girl was surprised and delighted.
Her mother's cunt was a lovely flower, smooth and juicy, pink and luscious.
Jerry crouched partly behind Laurie, one hand roaming over her round ass. The sight of his mother fucking his uncle's cock drove the boy wild with lust. Mesmerized, he gazed at the luscious globes of his mother's asscheeks. Christ, what a piece she was!
Laurie quivered and searched for the zipper of her brother's fly. She brought his cock out, held it in her hand. She slowly stroked his prick as she continued watching her mother and uncle in the living room.
The blonde teenager was thrilled at the idea of peeping like this, at the idea of seeing something they were not supposed to see. This was much more exciting than the other times she'd seen her mother fuck. Now her mother was doing something with Uncle Charlie.
Laurie was delighted to at last have a chance to see her uncle's cock. His prick was everything she'd expected it would be.
"Oh, Jesus, they're going to fuck!" Jerry whispered.
He was right. Ann was rising up to climb onto Charlie's lap. The teenagers watched as their mother squatted down, used her hand to position Charlie's cockhead in her cunthole. She slowly engulfed his thick prick with her hairless wet pussy.
When Ann leaned forward to put her arms around Charlie's neck, the teenagers on the veranda could see Charlie's cock in her cunt from the rear, his thick cockshaft stretching her cuntmouth between her full asscheeks.
Jerry and Laurie watched the couple on the sofa fucking. They watched their mother pump up and down on Charlie's big cock.
Charlie was sucking Ann's tits. He held a tit in each hand and chewed on her nipples one after the other. Ann pumped her ass gracefully, flexing her grinding her hips at the end of each down stroke. A flood of cuntjuice streamed out of her cunthole and ran down the shaft of Charlie's prick.
She'll ruin his pants, Laurie thought with a giggle. If her mother was as juicy as she was, Charlie's pants would be a mess after this fuck.
Now Ann climbed off Charlie's cock. She turned around so that her ass was towards his face and once again sat down on his prick. She began fucking again. Her eyes closed, her head thrown back, she bounced up and down on her brother's stiff cock.
Now the teenagers could see their uncle's hands on their mother's tits. Jerry fingered his sister's ass as he watched his mother fucking. Laurie quivered with excitement, her hand was pumping Jerry's cock.
Laurie moaned with pleasure now as she felt her brother move behind her. Jerry raised her dress, pulled her panties down and shoved his cock inside her wet cunt with one smooth stroke.
The two teenagers groaned softly as they began fucking. When they looked inside the room again, Ann was now kneeling on the floor and Charlie was behind her on his knees.
They watched as Charlie fondled Ann's ass. He ran his hands over her asscheeks, squeezing and caressing the luscious globes.
Leaning forward, he planted kisses over the entire surface of her ass. He pushed his face between her asscheeks and found her asshole with his mouth. A loud groan escaped Ann's throat as Charlie sucked gluttonously at her twitching bunghole.
The teenagers on the veranda were overwhelmed with excitement. They watched breathlessly as Charlie now positioned his cockhead on the tight ring of their mother's asshole.
"Oh, God, he's going to fuck her ass!" Laurie hissed. "I can't stand it!"
The teenage girl could feel her heart pounding as she watched Charlie's thick cock slide smoothly into her mother's sucking asshole.
She loved it, Laurie thought. She could see her, mother grimacing with pleasure as Charlie's cock stretched her shitter. There was certainly no sign that Ann was feeling any pain.
Gritting his teeth, Jerry held on to his sister's ass as he fucked her cunt. He kept his eyes glued to the scene inside the living room. It was hard for him to believe what he was seeing. There before his eyes his mother was getting fucked in the ass by his uncle. His mother's tits hung down like two heavy cantaloupes. She groaned and squirmed, wiggling her asshole on Charlie's thrusting cock.
