"Just a little more," Les rasped.
"Take it easy," Roberta hissed back. "But hurry!"
Les was about to complete the insertion of his hand into Roberta's voracious cunt.
Amy wanted to watch a real live in-the-flesh – in more ways than one – fist fucking.
"Now," Roberta groaned. "Now – hurry! NOW!"
"Alright, baby," Les growled back at her. "Here – it – COMES!"
He thrust his arm forward. His entire hand slipped slowly into the brunette's hungry cunt, right up to the wrist.
Roberta's thighs shook and threatened to give way. She screamed into the pillow. Amy couldn't tell if it was pain or pleasure, then decided that in Roberta's case the two couldn't be far apart.
She steadied, then called back. "Just hold it a minute; don't move," she pleaded. Les complied, and Amy all but forgot about the licking and sucking of her brother's big, hairy balls in her fascination with what she was seeing.
Roberta was evidently becoming accustomed to the awesome stretching because, within a few seconds, she was tentatively rotating her hips, pushing her cunt hesitantly back and forth.
Amy could hardly believe it. She couldn't imagine what it would be like to have anything that size up inside her own constricted teenaged pussy. Yet even as she watched, Roberta's movements became more eager.
"Ream me out!" the brunette hissed. "I'm dying for it!"
Les eagerly began ramming his hand back and forth inside Roberta's cunt. His hand went in up to the forearm before he began withdrawing it. Roberta thrust her hips back and up to meet the surging hand.
"Give me a fist!" she whined.
Amy heard her brother grunt as she reached up with her tongue and flickered it over his balls. Her hand came up to grip his hugely erected prick and slowly begin jerking on it. She could see the muscles of Les' arm tense as he struggled to comply with Roberta's wish, fighting the incredible elastic tightness of even the brunette's well-used or abused – cunt.
But then he was twisting his arm back and forth, literally reaming Roberta's cunt. Amy could tell from his prick jerks and ball jumps that Les was going to shoot soon. And Roberta seemed positively intent on exploding with pleasure.
"Now, Berta?" Les queried.
"Almost – almost…" Roberta gasped. Her hips went wild, gyrating crazily around the cunt reaming forearm and fist of the big man.
"Get my guts," Roberta groaned, shuddering and heaving, tits dancing tautly beneath him she came, flowing all over her lover's impaling arm.
The first spurts of hot cum shot out of Les' prick. Amy quickly shifted to cover the head of Les' cock with her mouth, regretting the loss of the view of her lover's final convulsive orgasm, but even more loathe to miss the chance to drink her brother's ball syrup. Her fist slid up and down over his cock as she sucked and milked his prick for all she could get.
Roberta suddenly screamed. Amy jerked her mouth away from Les' cock to see.
Les was withdrawing his hand from the brunette's cunt, but keeping his fist clenched. Amy stared, shocked and amazed, at the stretching of Roberta's cunt. She was fascinated by the writhing ecstasy evident in the woman from the abuse. Was it possible that she could achieve the same thing…?
Roberta convulsed a last time, then fell forward and flopped about like a beached fish. Les sagged above Amy, cock still drooling.
Amy was left to her fingers. She whacked off again and again, until her wriggles and groans roused Roberta. The older female slowly and languorously arranged herself in a '69' to the nubile teen.
Amy gasped and moaned with pleasure as Roberta sucked and licked her cunt and clit, then arched up as the brunette penetrated her cunt with first one, then two, then three fingers.
At first, it was a strain, but Amy began to acclimate herself to the stretching.
Les stirred. "What the fuck…" he groaned. And then stopped, silently watching as Roberta struggled, with Amy's willing cooperation, to work a fourth finger into the almost bald pussy.
"Hey, that won't work," he said in a worried tone. "She's too tight for it."
"Pussy will stretch a mile," Roberta grunted. "You told me yourself."
"Hey, Berta – she's just a kid!" he insisted.
Amy answered that – silently. She led her brother's hand to her tit and pressed it against the stiff spike of her nipple.
He yanked his hand away. "Stop, dammit!" he snapped. "Before someone gets hurt!"
"But I want it!" Amy protested. "I want to have…"
Les understood then – suddenly, in a flash, he saw what had happened. "Why, Roberta?"
"Why what?"
"Why did you do this – this manipulation. You used my sister. Now tell me why?"
Roberta's smile betrayed her. "Because you're so damned hung up."
"Wh-what?"
"You heard me. I figured if I could break down some of your inhibitions about yourself, you might cut down the rest on your own – the ones concerning me."
"Like what?"
"Like all those things I want to do, but you won't let me, that's what."
"You mean the dogs and horses and getting gang-banged and all the perverted stuff like that?" Les' tone was incredulous and angry. "Don't I let you…"
"None of those things are as perverted as fucking your own kid sister, are they?" Roberta demanded.
His kid sister writhed in desperate craving for her release beside them.
Les was confounded by the question. "We – well – if they are all that important to you, why don't you just go do them?"
"Because I want you, too. I want all of it, and I don't see any reason why I shouldn't have you and the rest!"
Frantically, Amy climbed onto her knees and shuffled to where her brother knelt on the bed. She quickly arranged herself on her back, legs wrapping around his waist, and slowly pulled herself towards him. His cock was hard, despite his anger, and she aimed at it with her open, wet pussy.
"What makes me so damn important?" he demanded.
Amy's cunt was inches from the tip of his prick. She used her trembling fingers to guide it downward.
"Because I love you, that's what!" Roberta shrieked as Amy's wet cunt made contact with her brother's cock.
"Fuck me, please fuck me," she moaned, opening her mouth like her pussy. "Please – please – please…"
"But you said you thought love was romantic bullshit!" Les accused. "There was only sex and compatibility!"
"I fucking lied!" Roberta yelled.
"Fuck me!" Amy gasped, managing to work herself forward until half of her brother's prick was in her pussy. She had to content herself with that and began driving her hips back and forth.
Les' breathing was becoming labored.
"Lying bitch," Les muttered. He glanced at his sister. "Now what do we do with her?" he demanded.
"Do what she asks," Roberta said. "Fuck her." The brunette crouched, straddling Amy's face with her furry pussy.
"But I mean after this. Look at her – a fucking nymphomaniac!"
Roberta giggled and moaned as Amy sucked her cunt lips eagerly. "Why, send her back home. You've got a little brother. And just think of what she can teach all those poor, healthy, horny, all-American hicks back in your home town!"
"Oh, Jeez, yes," he groaned, filling Amy's cunt and feeling it suck on his cock. "And my kid brother, and maybe her classmates, and I guess even Dad and…"
He suddenly realized that the list was endless and there was no point in naming it anyhow.
Besides, Amy was coming and he wanted to give full attention to the wonderful sensations her convulsing cunt was affording his prick.
