"Mmmmhmmmm....oh..yeahyeah....ohGodthat'sgooooood!" Elizabeth groaned as her brother worked his tongue into her stimulated pussyslit. She loved being licked and Jim certainly had a calling for it. She had led him to her bed for their sinful morning session, preferring its king-size space to the smaller bed in his room. Besides which, she had all kinds of lubricants and sexual paraphernalia in the nightstands in case Jim wanted to try anything unusual; she could almost bet that he would want to take her in the ass after his comment at the table and her current position could only remind him of that untried treasure. When they had entered the bedroom, she had cast her robe to the floor as she walked to the bed. Without looking back at him, she had yanked the cover and sheets down on her side of the bed and then crawled on the bed to complete the process on Julie's side. She had heard his shorts hit the floor and had felt his eyes drinking in the sight of her puckered poopshoot and the clam-like folds of her sex, nestling in the junction of her parted thighs. She lingered in that position, even arched her back a little to accentuate the sight. She didn't have to wait long for Jim to join her on the bed. The bed sagged, hands grabbed her ass and his nose and mouth dove into her inviting cuntcrack. "Oh, yeaahhhhh.....God, Jim!.....aaahhhyeaahhhh......eat me, baby!" His tongue began teasing the opening of her vagina; rimming, licking, squashing itself against the mouth of her cunt while his nose snorted hot air against the taut skin just below her asshole. Elizabeth hunched her ass in his face, moving her saliva-soaked slit up and down, feeling Jim's tongue cruise the length of her wet pink gash. "OOOOoohhhhhfuckyeah...mmmmmHHHMMMMMM!" Elizabeth's fingers tried to dig holes in the mattress as his left hand reached around and moved up to find her hanging tits. His fingers latched onto her left nipple and he shook her titflesh like a dog worrying a bone. At the same time, his tongue forced its way into her pussymouth. "OHGOD.....MMMMM.....that's it!....fuck me with your TONGUE!" she gasp as she shifted her weight onto her left elbow and threw her right hand between her legs to rub her clitty. Her fingers buffed her joybutton and beat against her brother's bobbing chin as his stiffened tongue probed her fiery furrow. The combination was too much for her and she felt her loins tear open in her first orgasm of the hardly begun day. Squealing like a banshee, she mashed her jittering womanhood against her brother's face, her cuntmouth clamping down on his buried tongue. Jim felt Beth begin to lose it and he fucked his tongue in as far as he could. Her syrupy quim got incredibly tight all at once, then it began loosening and squeezing over and over as her wails reverberated through out her bedroom. 'Fuck, she's juicing!' he thought as fresh pulses of pussy juice spilled around his twisting tongue. Beth flailed her cunt around so strongly that his tongue came out of her lush hole with a loud slurping sound. Jim breathing hard, watched her fingers dip up into her drenched slit, more juice oozed between her fingers as she fingerfucked herself through the end of her orgasm. After a moment, his sister slumped forward on her stomach as she drew her glistening fingers from her sated pussy. Jim, on his knees between her spread legs, ran his hand over her soft rear end. "Enjoy that?" he said and his sister rose up on her elbows and looked back at him. Her smile said it all. He ran his finger into the sexy cleft of her asscheeks. "I know what you're thinking," Beth said, "and we're going to need some lube if you want to try it." Jim's cock felt painfully hard as it was and the thought of assfucking Beth was almost too exciting. He'd never even get it in before he came, it was just too lewd and he was way to wound up. "There's nothing I rather try but I wouldn't last at all," he motioned to his extremely stiff erection, "it wouldn't even be a fuck...more like a quick deposit." Beth giggled and rolled on her back, raising one long stripper leg past his face as it cleared his crouched form. "Don't sweat it...we've got all day," his sister said as she rose back up on her elbows. "Would you like a blowjob?...it seems only fair that I return the favor." "Yeah, that would be great!" Jim agreed quickly. Her mouth had been on his dick in both of their previous sex sessions, once he hadn't known it was her but last night he'd known it was Beth's lips wrapped around his dick and BLAMMO, he'd gotten hard again real quick. Now she was offering to suck him off! "Well, come on," Beth said, remaining still. Jim crawled up toward her head, expecting her to roll over on her side and use her hand to hold him while she blew him. But she stayed on her elbows, her face turning to follow him. "Climb on me .. straddle me," she said up to him. "Sit on my chest and put that dick in my mouth!" 'Oh, man! This is awesome!' Jim thought as he swung his right knee over Beth's reclining figure and his hands reached down to cup her slightly flattened titties which were now just in front of his thighs. His dick jerked over them at the new feeling of power he had now....his sister's mouth was just in front of him. "All right, sis, open wide!" he said and she lustfully complied, her tongue laying out on her lower lip like a red carpet. He moved further up her body, feeling a nipple on the inside of his leg as he leaned over her, resting his weight on his left hand as his right fisted his shaft and pushed his bloated head down to her waiting mouth. Looking down his body, he watched his cockhead push through her parted lips and he lovingly humped Beth's hot mouth full of his crimson cock. "Awwww, yeaaahhh....Jesus....suck it!" he encouraged his big sister as he let go of his cock and his other hand swung out to support his weight. 'God, my baby brother is hung!' Elizabeth thought as her lips stretched around Jim's superhard whopper. He seemed much bigger than he had at the Whipping Post and she took that as a sign that he, indeed, wasn't going to last very long. "Jesus....suck it!" she heard him call out above her and she went to work with her tongue as he began a slow fucking motion between her lips. She closed her eyes and let Jim screw her mouth as her hands gripped his shins. Neither of them heard the front door open and close, even though the bedroom door was wide open.
