Linda had it exactly right, Marsha realized. The spasming sensation at the core of her brutalized cunt didn't lie. A climax was brewing within her.
"You feel like you're going to come, don't you, freak?" Linda asked.
Marsha nodded that it was true.
"A little more encouragement and you'd come right in Jerry's mouth, wouldn't you?" Linda said.
Marsha nodded again.
"I see," Linda purred. She took Marsha's tits in her hands and ran her palms over the stiff nipples.
"Feels so good," Marsha moaned.
"You're getting very, very excited," Linda told Marsha as if she had her cousin under hypnosis. "The pressure to come is building inside you."
"God, yes!" Marsha gasped.
"I can feel your heart beating a mile a minute," Linda noted, as she pressed her own small tits against Marsha's much larger one. "If I say the word you'll come, won't you? You'll do anything I say."
"Anything," Marsha agreed.
"Then when you come you have to do more than just fill my brother's mouth with pussy juice," Linda said, whispering hotly in Marsha's ear so Jerry couldn't overhear.
"What else?" Marsha asked with wild anticipation, completely under Linda's spell. "Just tell me and I'll do it."
"When you come," Linda answered, "you're going to come right in Jerry's mouth."
The instant Linda gave the command, Marsha felt her bladder ache. Suddenly it had to be emptied. The urge to piss was now just as strong in Marsha as the urge to come, the two tied together as if they were part of the same involuntary reflex.
"Come and piss, Marsha. Come and piss," Linda insistently whispered. "Come and piss in Jerry's mouth."
For emphasis, Linda slipped her hand into Marsha's crotch and expertly fucked her cousin's clit. That was it. The switch that triggered Marsha's climax and bladder.
"It's happening!" Marsha squealed orgasmically. "What a trip! I'm coming and pissing soooo hard!"
"So I see," Linda voiced her approval.
Linda had moved back to get a good view of the bizarre results her coaxing had produced. She saw Marsha's pussy drenching Jerry's face with its steaming yellow flood. Jerry thrashed like he might drown as the hot piss poured into his breathing passages.
"I can't stop coming! Can't stop pissing!" Marsha cried. She really believed what she was saying. So when her cunt quit spasming and gushing, she was disappointed that it was all over so soon.
This phase of the action finished, Linda helped Marsha dismount from Jerry's face. His features were red and swollen as a result of all the rubbing from his cousin's wire-haired cunt. His skin glistened from the sheen of female urine.
"You liked getting pissed on, didn't you?" Linda said to her dripping brother.
Jerry looked up into the cold steel of his sister's eyes and knew he'd better give her the answer she wanted. "Yes, Sis," Jerry choked, the bitter taste of pee in his mouth.
"But you'd like some of Marsha's shit even better, wouldn't you, brother dear?" Linda asked patiently.
Jerry flinched, but said yes.
"You know how to get it?" Linda chuckled.
Jerry stared at his sister blankly.
"You fuck her in the ass," Linda said, the raw tone in her voice seeming to surface from some gutter within her. "You stuck your big cock as far up her butt as you can go – until she screams that you're ripping her to pieces. But you keep fucking and fucking her ass until she thinks she's dying. Then you're ready to come."
Linda paused, enjoying the effect she was having on her brother and cousin. For her obscene description of what was going to happen had Jerry and Marsha breathless.
"But when you come you're not going to do it in Marsha's ass. You're going to pull out at the last minute," Linda continued. "That's where all that nice slimy shit comes in. Because when it's out of Marsha's ass your prick will be filthy. Then you're going to jack your shitty prick off so you shoot all over yourself. You'll be a real mess. All that crap and cum. But don't worry, Marsha will lick you off."
"You're sick, Sis!" Jerry blurted out.
Brother and sister locked eyes, temporarily ignoring their cousin.
"We'll leave it up to Marsha," Linda finally said to Jerry. "You don't have to fuck her in the ass if she says no."
Now Jerry and his sister turned toward their cousin. But Marsha wasn't where she had been.
There she was, leaning over a chair, kneeling with her ass in the air. Now she reached behind herself and pulled her ass cheeks apart. Her asshole throbbed in exposure, seeming to glow.
"There's your answer, Jerry," Linda told her brother, pointing toward Marsha's flared butt.
"Fuck me, Jerry! Fuck me right where I shit!" Marsha cried over her shoulder. "I want your cock in my ass so bad!"
Jerry was stunned. However, his prick was working properly. It leapt out from his crotch in twanging arousal.
"I love it in the ass!" Marsha was shrieking. "It hurts so good!"
"Give the little freak what she wants," Linda snapped to her brother. "Ten inches of prick where the sun doesn't shine."
Jerry stumbled forward, seeming to be pulled by the power of his hard-on. Then he was at Marsha's ass. Linda joined him, guiding her brother's cockhead to their cousin's asshole and fitting it into the rosy cunt.
When Jerry hesitated, Linda goosed him. His crotch bucked forward and he winced as the tightness of Marsha's ass grabbed his plunging prick. When he looked down half of his cock-meat was buried in Marsha's asshole.
"More! More!" Marsha begged. "More cock in my ass!"
"You heard her, Jerry," Linda said.
She goosed her brother again. Jerry wound up with his prick hilted in Marsha's ass chute.
"Can you feel her shit?" Linda asked her assfucking brother.
Jerry nodded.
"It's hot and slimy, isn't it?" Linda said. "Like worms crawling all over the head of your cock?"
Jerry gagged. His sister slapped him hard across the ass.
"Move it!" Linda ordered Jerry with another ass-reddening slap. "Work that shit loose inside Marsha so it smears all over your cock!"
Jerry's hips began to roll. Slowly at first. But then Marsha was tugging at his prick with the muscles of her ass and he was into a ass-fucking groove whether he liked it or not.
Now Linda turned her attention back to Marsha. "Hurt enough for you, freak?" she asked her panting cousin.
"Hurts just super!" Marsha wailed. "Like I'm gonna die! God, I love it! Hope it kills me!"
"You heard your cousin, Jerry," Linda said. "Fuck her ass like you were trying to destroy her."
Jerry didn't need any more prompting. His cock was pistoning automatically in the first ass it had ever fucked. The cock-strokes were as long as they could get.
"Gonna come!" Jerry soon gasped, reacting to the nut-wrenching friction.
"Pull out!" Linda barked. She grabbed a fistful of her brother's hair and yanked his head back.
Jerry's prick popped free of Marsha's ass. Just as Linda had predicted, it was covered with shit.
"Jack off." Linda snapped.
Jerry wrapped his fist around his brown cock. The shit oozed between his fingers. A single jerk and he was creaming all over himself.
Then Marsha wheeled around and was all over him, lapping away the crap and cum. Her tongue was all over his fingers, cock, balls, and crotch. She didn't stop until the slime was all gone. When she was finished her mouth was smeared at the corners with brown and white as though she had been eating fudge and marshmallows. She smacked her lips with triumph while Jerry sagged with exhaustion.
"Fantastic!" Marsha sighed, feeling dirtier than she ever had in her life.
She turned to thank Linda for pushing her to the limit. However, her cousin was not there to thank. "Linda's gone," Marsha murmured to Jerry with a shake of her head. "Just like that. Just like she was never here and we imagined the whole thing."
