Julie lifted her mouth, kissed the head of her son's cock, and asked in a husky voice. "Do you like it?"
"Oh, Mom, it sure feels better than being jacked off!" Bobby grunted.
"Mamma, I know," Julie agreed. "I'd rather suck it off than jack it off, too."
"What if I have to come, Mom?"
"Oh, yes!" Julie gurgled. "Come all you want to, baby."
"In your mouth?" Bobby asked, his eyes wide. "It's okay if I come in your mouth, Mom?"
"Bobby," Julie said in her throaty voice, pulling at his young balls, "I wouldn't suck your cock if I didn't want you to come off in my mouth."
"I can come in your mouth?"
"You damn well better!" Julie giggled.
Carol's mind was reeling. It was the most erotic thing she had ever experienced! The very fact that it was a mother getting ready to fuck her son's cock off was exciting enough but it was even more thrilling because it was her sister and nephew.
Julie twisted her wet, long tongue about her son's cock again, whimpering softly as she tasted it. Her eyes flashed and with a hungry growl as she sucked her son's cock deeply into her mouth once more.
Carol watched with boiling, misty eyes as her sister ran her lips up and down Bobby's hard cock swiftly, from the very base to the swollen head. She saw her nephew twisting his naked ass on the bed, staring at his mother's mouth.
She also saw Julie's uplifted ass trembling with cock-sucking pleasure and listened to her wet sounds of ecstasy.
Bobby was trying hard not to move, fascinated by watching his mother bob her lovely face up and down, her lips burning hit cock, her tongue licking.
Again Julie lifted her mouth.
"You don't have to be still, honey," she said in a whispery voice. "You can move all you want."
With a grunt, Bobby arched his ass up and Carol saw the head of his cock stab between his mother's lips. Julie gave a soft cry of pleasure and let her son fuck her mouth for a while. Then Julie began to ram her mouth down as her son came up. Carol's legs were weakening as she watched. It was intensely fascinating to her, seeing Bobby fucking Julie in her mouth. The sounds coming from Julie sent shivers of feverish pleasure through Carol's body, making her cunt burn with a fierce hunger. Carol licked her lips, almost feeling Bobby's cock in her mouth, too.
Although Carol had sucked cock before, she had never seen anyone else do it. Watching her sister with her mouth filled by a hard cock was exciting her more than she would have suspected. Bobby, as young as he was, didn't have a large cock, and it looked to Carol as if it would be very easy to take his prick completely into her throat. She was hardly aware that she was swallowing time and time again.
Her cunt was burning against the wet crotch of her panties and she felt as if she would come as she watched them. The cheeks of her ass bunched up and then relaxed, only to bunch up again. She squeezed her thighs together and the pressure on her puffy cunt was almost too much for her to stand.
"Suck hard, Mom!" Bobby grunted, ramming his cock up into his mother's mouth. "Suck my cock real hard! Oooh, this is so good, Mom! Your mouth is wet and hot and… Oh, suck it, suck it, Mom!"
Julie was devouring her son's cock hungrily, her lips sliding up and down wetly. Although Julie's eyes were open, they rolled about and had a glazed look in them. Carol had seen that look on her sister's face many times before, usually in the back seat of a car with a boy's hand up her skirt. It meant her sister was about to come. Julie was hunching her hips now, moving as if she had a cock up her cunt, fucking it while sucking on Bobby's cock.
"Mom!" Bobby groaned, his half-naked body shaking. "I don't think I can hold back! It feels like I'm going to come, Mom!"
With a muffled squeal, Julie began to suck faster yet at his cock. She went up and down frantically, twisting her head from side to side as her lips squeezed the hardness. She moaned deep in her throat and Carol watched her sister struggling to bring the hot come juice out of Bobby's balls.
With a groan, Bobby came.
Carol knew he was coming because she saw his balls draw up tight, then watched them pulsate. She heard the wet swallowing sounds Julie made and saw her throat working. Bobby moaned and twisted about as his cock flooded his mother's mouth. Julie had shaved her hands behind her son's ass, her fingers clutching the tight cheeks, lifting him up, drawing his gushing cock deeply into her mouth. Her eyes were closed now as her face took on the expression of a woman experiencing the utmost ecstasy.
As Bobby finished squirting into his mother's mouth, Carol finally began to move. She slipped away silently, going through the house and out the front door. She stood outside in the bright sunlight, undecided. She knew she should return home, yet something held her there. A glance at her watch said it was only eleven in the morning. She could return home, but Carol knew that once she was alone in her home, there was nothing to prevent her from stripping her clothing from her now-feverish body and finger-fucking herself raw. But Carol didn't enjoy finger fucking herself, not when she was alone. She stared at the closed front door, her finger hesitating near the bell. Surely Julie and Bobby would be finished now. Maybe Julie was in the kitchen, preparing herself a glass of iced tea, a beverage she drank summer and winter. Maybe Bobby was taking a shower. She found herself forming a mental image of him behind the glass doors, seeing him washing his cock and balls and ass, thinking he was alone. She pictured him maybe sneaking his hand down and jacking on his cock. She shivered.
She punched the doorbell.
It seemed a long time before Julie opened the door.
"Carol! You know you don't have to ring that damned bell," Julie said as she looked, at her sister. "You've never done it before, why now?"
Carol shrugged her shoulders her straining tits moving in a tight way.
"Brad called that Bobby wasn't in school," she said, entering the house. "I wondered if he was ill or something."
Julie sat on the couch, her iced tea on the coffee table. "No, I had something for him to do. He'll be leaving in a few minutes. I just called the school."
Carol sat at the other end of the couch, feeling nervous. She felt her sister's eyes on her and wondered if Julie had known she was in the house earlier. A faint blush crept over her face, but not because of shame. It was because her cunt was still on fire, her emotions swimming about with erotic desire.
"You seem nervous, Carol," she heard Julie say. "Is anything wrong?"
"No," Carol said, hearing her voice quiver. "I have something on my mind."
"Want to talk about it?" Julie asked.
Carol looked her sister square in the eye. "I'd love to talk about it, Julie, but…"
"Hey, this is Julie," her sister said. "We don't have secrets from each other. We've always talked about things, Carol. It's a bit late to clam up now, don't you think?"
"It's kind of personal, Julie."
Carol wasn't sure, but she thought her sister's eyes had glanced at her full tits, then down at her thighs.
"Want some iced tea?" Julie offered.
"No, I'd…"
She felt Julie's eyes on her. She wrung her hands in her lap and the movement caused her skirt to ride past her knees. She tugged at it, wondering why she was bothering. She and Julie had seen each other naked many times and neither had been modest in front of the other.
Bobby came into the room, causing Carol to stop talking. She tried not to look at him, but found her eyes going to the front of his pants. She jerked them away when she realized Julie was watching her closely.
"I gotta go now, Mom," Bobby said, kissing his mother's check.
Julie patted her son on his ass. "Hurry straight home when school is out, honey. Remember?"
"Yeah," Bobby grinned, and Julie saw his eyes gleam.
