With her eyes still gazing at Bobby's cock, Sandra replied, her voice soft, "I been there long enough, Joyce. I saw what you did to Bobby."
Joyce was silent for a while, looking at the girl. Finally she said, "Does that interest you, Sandra?"
"What?"
"Bobby's cock," Joyce chuckled throatily. "You're certainly staring at it hard. Does my son's cock interest you, honey?"
"I never saw it before," Sandra said in a voice that was becoming excited.
"But you've seen the cocks of David and Mike, haven't you?" Joyce said. "You've seen those cocks. Is there a difference?"
Sandra glanced accusingly at Shari. "You wasn't supposed to tell, Shari," she accused.
"You mean you don't know?" Joyce asked. "About your brothers?"
"Know what?"
Joyce realized that David and Mike had not said anything to their sister. Sandra did not know what she and her children had done with them. She dropped her line of questioning for the time being. Joyce saw that her son's cock was swelling again, arching up from the fringes of his cut-offs.
"Lift your dress!" Joyce said suddenly.
Sandra's eyes widened, turning back to Joyce. "But I didn't do anything, Joyce," she protested. "All I did was help hold Shari. I didn't do anything to her."
"You helped hold her," Joyce replied. "Don't you think that's enough? Shari didn't want to fuck, did she?"
"She said she didn't," Sandra conceded.
"Then why did you hold her for your brothers?"
"They wanted to fuck her," Sandra said, as if that was all the explanation necessary.
"Lift you dress," Joyce said again.
"I don't… don't wanna do that," Sandra protested, but she was once more gazing with interest at Bobby's cock, now straining up in full hardness.
"Shari didn't want to either," Joyce reminded the blonde girl. "Now this will make it even. You helped your brothers fuck my daughter, so it's only right that I help my son fuck you. Now, lift up your dress!"
Sandra had no choice, and she knew it. She pulled her dress up, stopping at her hips.
"To your waist," Joyce said. "I want you to pull your dress to your waist."
Sandra did as she was told, and Joyce was amused to see the little girl shoot coy, flirting glances at her son. Sandra had on a pair of very tight white panties. She looked appetizing, standing there with her skirt about her waist.
"Shari, pull Sandra's panties off," Joyce said.
Shari was eager to comply, and she began to strip the tight panties from the shaking girl. Sandra stepped out of them, still holding her skirt high. Joyce saw the girl had the faintest of blonde fuzz on her sweet-looking young cunt, fuzz that was quite appealing. She told the girl to turn around, and all three of them looked at the sweet swell of her saucy ass. Bobby could not keep his hands off Sandra. He moved close to her and felt about her sweet ass cheeks. Joyce was amused by his interest, thinking of how he was always feeling her ass.
"I think my son wants to fuck you, Sandra," Joyce said. The heat of the day was forgotten during the excitement. None of them were bothered by the temperature now.
"She's gotta suck my cock, Mom," Bobby said, his voice cracking with excitement. "I want Sandra to suck on my cock!"
"But I didn't… my brother's didn't do anything like that with Shari," Sandra protested, her voice barely a whisper. The sweet cheeks of her saucy ass quivered, and Joyce wasn't sure if her tremors were from fear or desire.
"Have you ever sucked a cock, Sandra?" Joyce asked.
"No." The girl shook her head.
"Shari had never been fucked before either," she reminded the girl. "Since you have been fucked, then you're going to have to suck on Bobby's cock."
Sandra was facing them again, still holding her skirt high, as if she had forgotten it. Her eyes darted to Bobby's throbbing prick again, and she licked her lips nervously. "I don't… do I have to, Joyce?"
"You do," Joyce replied. "Get on your knees, honey. You might learn to like being a cocksucker! Okay, let's not fuck around anymore… get down on your knees!"
Shaking, Sandra dropped to her knees, and Bobby immediately stepped close to her, his cock waving in her face. He was holding it tightly, arching his hips forward, his eyes burning with desire. With his other hand he grabbed Sandra by one of her long ponytails, bringing her face close to his cock. He smeared the dripping piss hole back and forth on her lips.
"Mmmmm!" Sandra grunted, her lips tightly together. She was trying to shove him from her face by placing her hands on his hips, but it didn't do her any good.
"Open your mouth!" Bobby demanded, pressing his cock against her tight lips. "Come on, Sandra! Open your fucking mouth!"
"Don't be so rough, baby," Joyce said. "She'll suck your cock. Just don't be so rough with her." She watched her son stop shoving. "Sandra, you've got to take his cock in your mouth. Open your lips. You'll love it, I promise you that."
Sandra allowed her lips to open slightly, and Bobby brushed them with the head of his dripping prick. He felt her teeth against his cock, then her teeth moved aside. He pressed his prick into the kneeling girl's mouth. Sandra closed her lips about his cock, and her blue eyes gazed into his face. She held his hips still but was not trying to push him away now.
"There, you see," Joyce said. "That isn't so bad, is it, Sandra? Just start sucking on his cock! That's all there is to it! Suck him Sandra! Suck Bobby's cock, honey!"
Joyce saw the change in those blue eyes. Apprehension was no longer in them. Now they sparkled with a deep interest, with a desire. Sandra began to suck on Bobby's cock slowly, becoming accustomed to his prick in her mouth. As she felt more comfortable, she began to use her tongue to lick on his cock as her lips glided back and forth. Her small, but very shapely body, trembled, but the tremor was from bubbling pleasure now. Her mouth filled with his dripping juices, and she had to swallow often. Joyce remained in her chair. Shari now stood beside her mother. They both watched the blonde girl sucking on Bobby's cock, excited smiles on their faces.
"She likes sucking his cock, Mom!" Shari said. "She really likes it!"
"I would say so, darling," Joyce replied, squeezing at her tits. "Yes, I would say that Sandra is going to be a very good, and very eager, little cocksucker!"
Bobby was dancing about with enjoyment, holding the back of Sandra's head as she sucked him. "Her mouth is sure hot and wet!" he shouted to no one in particular. "Wow, I like the way Sandra sucks cock!"
"Eat him up, Sandra!" Shari urged in a thick, excited, little-girl voice. "Eat his cock up! Suck him off! Make Bobby come off in your fucking, cocksucking mouth!"
Bobby moved his hands to the girl's shoulders, pumping his cock back and forth as she sucked him. He was so excited by having Sandra suck his cock, he could not remain still. He pulled the fringed leg of his cut-offs far to one side, so his balls were exposed, too. He would have taken his shorts off, but that would mean Sandra would have to take her mouth off his cock, and he didn't want to lose this pleasure, not for a second.
"Ohhhh, suck it, Sandra!" he yelled. "Suck my cock! That's good, Sandra! Suck it good for me!"
Sandra could feel his cock throbbing against her tight, wet lips. Her tongue rolled and lapped, and she felt as if her little mouth was stuffed more than her mouth had ever been stuffed in her life. Yet she found having his prick in her mouth was good, almost as good as having her brothers' cocks fucking into her tight, hot little cunt. There was no thought in her mind what she would do when he came. She was far too involved just from sucking him right now. She liked the hotness of his prick, the smoothness of his cockhead sliding over her tongue. She enjoyed the way his body trembled against her hands, and her little, tight ass twisted and writhed, her cunt throbbing and becoming extremely wet between her smooth thighs.
