"Once or twice," he admitted. "Yeah, it was fun."
"Then play with me like that. We can pretend we're hiding from our parents so we can be nasty. You can pretend I'm your little sister and you take my panties dawn and look at my cunt. I'll pretend to be real shy, and you have to make me touch your cock and play with it."
"You like to play like that, Mom?"
"Sometimes," she said, caressing his chest. "Wouldn't you like to have a little, sister like me? A pretty little sister you could fuck, too?"
"Wouldn't, you get mad about that?"
"I might play, with both of you." Lisa grinned. "Wouldn't it be fun to have a little sister you and I could play with, play with her little cunt and sweet, ass?"
Johnny nodded, becoming excited.
"I'd suck you both, too, Johnny," Lisa went on. "I'd teach her how to suck your cock, and I'd lick her hot little cunt and we could do everything with her, couldn't we?"
"Yeah, Mom! I'd suck her ass, too!"
"Mmmm, I feel your cock getting hard again, baby," she cooed. "What would you like to do with it this time?"
"Fuck you in the mouth, Mom!"
"You love to fuck mother in the mouth, don't you?" Lisa giggled wantonly, turning to lie back on the couch. "Come on, fuck my face, baby."
Johnny climbed onto the couch, sliding up her body, his balls rubbing over her tits. Lisa ran her hands up his thighs to his ass, opening her mouth as his cock came close to it. When he leaned over her face, she pulled his cock into her mouth.
Johnny began to move up and down. Lisa clutched his slippery cock tightly with her lips, feeling his balls rub at her chin when he pushed his swollen cockhead to her throat. As she sucked her son's cock, she imagined having a little daughter watching them, feeling her soft cunt at the same time.
She fantasized about the night before as Johnny fucked her mouth, about being naked outside on the sidewalk with him. She wondered if they had been seen, and hoped they had.
Lisa began to squirm her ass on the couch as her son stabbed in and out of her mouth. She wanted to play with her son, do things with him that would shock others with his cock running in and out of her mouth, she thought of the most perverse things possible, and found her ecstasy growing very hotly.
"Mom!" Johnny moaned. "You really wish I had a sister?"
"Mmmmnm!"
"And you'd let us fuck?"
She moaned, her eyes flashing up at his excited face, nodding her head as his cock kept thrusting into her mouth.
"And you'd play with us, too?"
Again she nodded her head, a little more vigorously.
"Ohhhh, Mom, my cock…"
Johnny began to fuck her mouth faster.
Lisa clutched his naked ass, feeling his cock throb. She closed her mouth as tight as she could around it, her tongue pushing hard.
"Mom! Ohhh, Mom!"
Lisa whimpered around his cock as he rammed into her throat. She knew he could not resist that powerful urge to push at the moment of his discharge. His balls smashed against her chin. She clenched his asscheeks.
The hot spurts gushed, flooding into her throat. Gulping quickly, Lisa began to swallow jizz as her son squirted over and over. Her cunt steamed with wetness, the hairy lips were swollen, her clit was pulsating stiffly.
With Johnny coming in rapid spurts Lisa jerked on the couch, her legs opening and closing. She began to come in wave after rippling wave of contractions.
Johnny weakened as he leaned over her face. The cheeks of his ass lost their tenseness, and his cock began to soften between her lips.
Lisa began caressing his ass, the backs of his thighs, her tongue moving over his softening cock until his gentle shivering stopped.
"I thought my balls were gonna come off," Johnny gasped as he lifted from her face. "I don't think I came that hard before."
He sat down at her feet, running his hand up her thigh to the soft hairs of her cunt.
Lisa licked her slightly bruised lips, her eyes moist with affection for him. She let her legs splay outward so he could see her pink, hairy cunt.
"I love it when you come so hard, Johnny," she said, licking the corner of her lips. "It shows me you love it."
"Mom, did you mean it when you said you wished I had a sister?"
Lisa nodded.
"That would be so nice," Johnny said. "But I love what we're doing. I don't really need a sister."
"I'm just fantasizing, baby," Lisa said. "Fantasizing can be a lot of fun, sometimes."
"Then you really wouldn't play with a girl?"
"I don't know. It would depend on the situation, I suppose."
"But seeing someone else isn't just fantasizing."
"Oh, no. I believe you'd really enjoy that, I certainly did that one time."
"Maybe we will…"
A day or so later, Lisa and Johnny went walking in the late evening with the intention of finding some place to fuck as they had in the post office. It was another very warm evening, and Lisa wore a wrap-around skirt, like a sarong, with a halter over her tits. Johnny wore a pair of blue running shorts.
Although fucking in the well-lit post office had been very exciting, they searched for a different place, wanting the excitement to be the same, yet different.
Lisa had tied her skirt loosely, so her long thigh showed as she walked. Now and then, Johnny wold pull on her skirt to look down at her bushy cunt, making his mother giggle.
Once, they rounded a corner while he was tugging at her skirt, almost bumping into a man walking his dog. Lisa jerked her skirt together just in time. They giggled over what the man's reaction would have been if he had seen.
Loud rock music was coming from one of the houses, and Lisa and Johnny paused. The house was dark except for one window. They looked at each other, grinning and nodding.
