Sarah noticed that Judy spent quite a while on the phone that afternoon.
Curious as she was, Sarah didn't question her daughter or listen in on the conversation. She suspected, though, that she was talking to boys, maybe those she had seen in the park jerking off.
Since that day in the park, Sarah had watched her daughter become progressively more demanding in sex. Part of it was because of her, their mother, Sarah realized. Since there was no longer any reason to conceal her desire to fuck, Judy had simply allowed her erotic nature to run its course.
The changes in the household had come about swiftly. Before the day in the park, Sarah and her son and daughter had always carefully closed bathroom doors and seldom allowed any part of their clothing to reveal a body part that could tease or entice. Now, bathroom doors were never closed, and most of the time all three were naked, even in the back yard. They swam naked, pissed where they happen to be, and if they should happen to have clothing on, clothes were always arranged to reveal a tit, a cunt, or a cock, or the flash of a pretty ass.
The sense of freedom about the house was a good feeling for Sarah. It was something she had wanted to do for a long time. Before all this began, Sarah would walk about the house naked when Tony and Judy were in school, feeling good. Sometimes she had worn only her panties, maybe a bra. She would fantasize of being watched by someone through a window, and usually that was enough to make her come without touching herself. She had never mentioned that to Judy or Tony. It was one of those private things a woman enjoyed secretly, and it would remain that way.
School would be starting in a few more weeks, and Sarah dreaded that day. Once again she would be alone all day, and that would be hard to bear, especially after being with Judy and Tony almost constantly, fucking, sucking, wrestling and in general cutting up, having a real ball. In a few more weeks she would be climbing the walls until they came home.
She wondered if her daughter could stand it, too. But knowing Judy as she did now, Sarah knew Judy would find some means to satisfy her hot little ass, even at school. Sarah laughed at the idea of getting a note from some shocked teacher that her daughter was taking on all corners in a dim corner of the school halls or in the bathroom.
The thing that pleased her most was the total lack of jealousy between all three of them. Tony felt no jealousy about his sister or her. He thought it was childish for guys to stand around a naked girl and beat off, but then what boy wouldn't if he was getting the real thing? But he didn't care if his sister did it, or even if his mother did, too. He often talked about a certain girl he knew at school that he thought would be fun to fuck. He talked about the girl's ass and the way her tits stuck out and how pretty she was. And, he would get a hard-on as he talked about her, telling his mother and twin sister that, when he was lucky enough to catch a glimpse of her panties, he would almost come in his pants.
"I'd drink five gallons of her piss to lick the place it comes from," he said.
"Guys have been saying that about girls for five thousand years, silly," Judy giggled. "And you wanna know something? I bet not one would do it, either."
"I would," Tony insisted.
"Then why don't you do it for me?" Judy demanded.
"You're my sister."
"I'm your fucking sister, shit head," Judy reminded him. "I'm the sister you can fuck when you're horny. If I let you fuck me, then you should let me piss on you the way you want that little ass wiggler to do."
"Ah, you're different, Judy."
"Don't I wiggle my ass cute enough for you?" Judy insisted, standing up and wiggling her small ass wildly. "See? Don't my ass make your cock hard?"
Sarah laughed at their antics. She understood what her son was saying, but apparently Judy didn't.
"You're my sister, Judy," Tony said again, as if that explained everything.
"Well, fuck you, darling brother," Judy said, sitting down next to him. "I'll have you know I can get any guy I want. I don't need your old cock anyway."
"Okay, kids," Sarah said. "Fun is fun, but let's not get mad, okay?"
With a giggle, Judy grabbed her brother's cock and pulled, making him yelp. "I was just teasing, Tony."
"I gotta think about it, Judy," he said.
"Think about what?"
"Letting you piss on me."
"I could've done it anytime," Judy said, pulling and stretching his prick. "Before you knew it, I could've pissed on you. In your face this morning when you were sucking my cunt, for that matter."
Sarah said, "She's right, honey. You were so damned excited, coming in my mouth, she could have pissed in your face then and you couldn't have stopped it for anything."
Tony grinned sheepishly. "Yeah, I know." They were again sitting on the patio, and the sun was going down. Sarah wore panties, a pair of very lacy ones that clung to her hips and ass like a second skin. That was all she wore. Both Judy and Tony were naked. They were still wet from the pool. Sarah drew her knees up, tossing them over the arms of her lounge chair, her crotch revealed. The dark hair of her cunt was visible through the tight, almost sheer panties. She idly rubbed a finger along the edge of her panties near her cunt as she listened to them talking and teasing each other.
She thought about pissing, how it had felt when she and Judy had pissed on each other's cunt the other day. It had felt warm and good, delicious even. The day she had shoved her face into the stream of her son's piss in the pool had excited her, too. The act of pissing had an erotic appeal to her. It was fun to watch Tony or Judy piss. It was exciting to watch them piss.
She hooked her finger into the crotch of her panties and pulled it aside, her other hand fingering the puffy hairy lip of her cunt, drawing it up to caress her cunt. Judy and Tony watched her, and Tony's cock was swelling underneath the fondling hand of his sister.
Sarah pulled the crotch of her panties back over her pussy. "Speaking of pissing…"
She began pissing then.
The crotch of her panties became soaked immediately, and her daughter giggled while Tony made a moaning sound.
"Move your panties out of the way, Mother," Judy said, her voice quite throaty for a girl her age.
Still pissing, Sarah hooked her finger into the crotch of her panties again, pulling it wide. The stream of piss spurted out in a high arc, splashing upon the knees of her son and daughter. Judy made a cooing sound and began running her hand about her piss-wet knee, then Tony, too, smeared it along his leg. They watched her, their young eyes glazed with excitement, staring directly into her cunt as she pissed onto their legs.
Tony's cock jerked into a quick hardness, and Judy moved her other hand quickly to her own cunt, rubbing swiftly.
With a husky laugh, Sarah began pulling the crotch of her panties over her cunt, then away. She pissed all the time she was doing this, letting her panties become even more soaked, then pissing on their legs again.
"That's it," Sarah said as she stopped, squirting one last stream a few feet away. "I can't piss anymore, kids."
"Mother, that was… was lovely!" Judy squealed, smearing her slender thigh with the warm piss. "I'd love to have a picture of you pissing that way."
"And what would you do with it?" Sarah said. "Show it to all your friends?"
"I wouldn't do that," Judy said. "I'd put in on my mirror in my room."
"Along with all those rock stars, huh?" Sarah giggled.
Tony snorted. "Who wants a fucking picture like that?"
Judy poked her brother in the ribs. "You could use it and jack off, dummy."
"Who wants to jack off when he's got all this cunt around, Judy?" he said. "Besides, who could jack off in peace with you around? You'd be sucking a guy's cock before he knew it."
"You fucking well better believe that!" Judy laughed, and stroked his cock.
"No matter," Sarah said. "I won't have a picture of me pissing floating around anyway."
Judy leaned over her brother's lap and circled the head of his cock with her wet little tongue. Tony shoved the back of her head, and Judy made a strangling sound as his cock fucked deeply into her throat.
For a moment Judy tried to get away, but, when her brother held her head down and started fucking into her mouth, she stopped struggling and began to moan with delight.
From where she sat, Sarah could see it all. She saw her daughter's lips drawing tightly on her twin brother's cock as he fucked her mouth. She had her small hand holding his balls, twisting and squeezing them, taking the full hard length of his cock into her mouth with no trouble at all. Sarah licked her own lips hungrily as her eyes blazed in erotic pleasure. She began to rub her cunt again, feeling the piss-wet crotch of her panties, finding the sensation amazingly good.
"Oooo, fuck that little mouth, Tony!" Sarah gurgled. "Fuck your sister's hot little mouth!"
Judy plunged her face down every time her brother lifted, taking his throbbing hard-on deep. As Tony drew back, Judy sucked up, moaning with ecstasy.
"Use her cocksucking mouth, Tony!" Sarah urged, twisting her own ass, her hand pressing hard against the piss-wet crotch of her panties, shoving the fabric into the hairy slit of her cunt. "Use her cocksucking little mouth fuck her in the mouth! Use it as if it was her hot little cunt, baby! Mmmmmmm, suck that big cock, Judy! Suck his prick… drink his come juice, honey!"
Judy had slipped from the lounge chair to her knees at her brother's side, gobbling greedily, her saucy, naked ass twisting cutely. It was difficult for Sarah to tell if her son was fucking Judy's mouth or if her daughter was sucking his cock.
"Suck hard, Judy!" Tony yelped, fucking his prick deep. "Suck my cock! Ohhh, your mouth is so fucking hot and wet! Eat my cock… lick my prick!"
Judy seemed to be trying to pull his hairless balls off, stretching them and twisting with her hot hand. Sarah, now, had stuffed the crotch of her panties deep into her bubbling, hairy cunt, fingerfucking herself. Her son was watching her as he fucked his cock in and out of his twin sister's mouth, still holding the back of her blonde head.
Sarah ran her tongue over her lips with hunger, straining to see Tony fuck Judy in her mouth as the sun disappeared. The patio lights had not yet been turned on, and it was starting to become hard to see clearly. Lifting her ass, using the arms of her chair for leverage, Sarah wiggled her hips in a tight circle, her finger pressing the crotch of her panties into her boiling cunt. She thought about going to her kids and taking his balls into her mouth, sucking on them as her daughter sucked his cock. Yet, the excitement of watching this mouth fucking was intense, and she didn't want to move.
Judy sucked frantically on his throbbing cock, feeling that smooth, round prickhead probe her constricted throat. It was so good to her that her small pussy started bubbling with hot orgasms. She gurgled and squealed about her brother's cock as her tongue licked furiously.
Darkness came quickly, and Sarah could only see the dim forms of her kids now. Pulling her finger from her cunt, she stood up and stripped her wet panties off. Dangling them from her finger, she started toward Judy and Tony. At that moment Tony started coming.
Judy choked in a dainty way, swallowing the creamy come juice as he spurted into her young mouth. Tony gave a yelp of ecstasy as he felt his sister sucking harder, her tongue pressing at his erupting piss hole.
Sarah moved fast, and, before her son knew what she was doing, she pressed the crotch of her panties into his open mouth. Tony, tasting his mother's cunt on them and the wetness of her piss, sucked at her panties. Sarah went to her knees and shoved her face into his crotch, pressing her daughter's hand away. She gulped her son's hairless balls into her mouth quickly, her cheek brushing that of her daughter. Sarah could hear the wet swallowing sounds Judy made, and that increased her excitement. She knew the joy Judy was feeling, sucking on Tony's spewing prick and swallowing his delicious come juice. She could feel his sweet balls writhing in her mouth as he came, and her hand moved out to feel Judy's boiling little cunt. Working a finger up her daughter's cunt, Sarah finger-fucked swiftly.
Then Judy lifted her mouth, saw her brother sucking on the wet crotch of her mother's panties. "Let me!" she squealed, and jerked them from his mouth, stuffing them into her own, sucking noisily, wiggling her ass about.
Sarah, almost out of her mind with desire now, pressed her daughter onto the grass and buried her mouth into that sugary cunt, drawing her knees up beneath her stomach, hr creamy ass in the air. She clung to Judy's naked little ass when her daughter pressed upwards, grinding her cunt into her mouth.
Judy sucked at the piss-wet crotch of her mother's panties as she bucked her ass up and down, grinding her cunt into her mother's face and tongue, coming hard.
But after a while Judy could take no more. She began pushing at her mother's head. Judy removed the panties from her mouth and groaned, "Stop, Mother! Ooooo, I can't take any more! Please, you're eating my cunt off! Don't… not any more!"
Sarah pulled her mouth out of Judy's wet cunt, letting her daughter relax. She was still steaming, and she turned to her son, who sat with his legs spread wide. "I want that," Sarah moaned, and she sucked his cock into her mouth.
Sarah fucked her fingers into her own cunt brutally, clawing at her fiery cunt, her naked ass twisting erotically. She devoured her son's cock, making his prick swell with her lips and tongue.
"Mmmmmmm, come in my mouth!" Sarah urged, running her tongue around the head of his cock. "Come in mother's cocksucking mouth, Tony! Fuck my mouth the way you did Judy's! Come on, I want it… fuck my cocksucking mouth!"
Tony's cock was half hard as she gobbled frantically at his prick. He moaned, straining.
And he started pissing in his mother's mouth…
