"Yaaaaaagh!" she cried, gasping and panting.
"My God!" Whit cried with a touch of awe. "You just started on her, baby, and she's coming already!"
"Whit! Whit! I'm coming! Ohhhhh, Whit, she's sucked my pussy off and made me come!"
Monica clutched at her brother's arm and pulled his hand tightly against her swollen, throbbing tit, making him mash it flat against her chest with his squeezing fingers.
Her thighs shuddered, and her butt twisted and jerked in the seat as her pussy burst forth with a flood of juice and quivered wildly against the pressing tongue and lips.
Carla licked and slurped, using the flat of her tongue, sucking up all the thick, syrupy honey that flowed from Monica's virginal pussy hole.
"Mmmm, so sweet!" she gasped, pulling her mouth away for just a moment, licking her lips. "Sweet pussy juice, Whit – I want more!"
"Ohhhhh, not again – stop…" Monica wailed. "Ohhhhhh, it's not right – not right!"
Carla paid no attention. She scooped her hands under Monica's quivering butt cheeks and lifted her ass from the seat. Her pussy seemed to spread open even more, and her thighs turned up and outward to give Carla more access to the center of her being.
At the same time, she felt her brother gasping harshly against the side of her face. His hands pulled at the shoulder of her dress. Then he reached at the back of her neck and found the tab of the zipper there and began lowering it.
"Whit – Whit…" Monica cried, tossing her head, feeling overwhelmed by the lust inside her and the incestuous intimacy of her brother.
"Ahhhhhh, Sis," he gasped. "What a hot twat you've got! God, you really need it, don't you. Give her another one, Sis – go on, come right in her sucking mouth again while I… ohhhhhh, man, what terrific tits, Sis!"
He'd opened the back of her dress and pulled the garment from her shoulders, sliding it down her arms until her tits were bare. Then he'd lifted her mesh bra up over them and made them completely naked.
Monica groaned helplessly. Her pussy was being sucked and licked again by Carla's flickering tongue. And now her tits were being mauled by her brother.
The top of her head nearly came off when she felt his hot breath on her succulent mounds and knew exactly what he was going to do next. Her own brother!
His lips parted. They sucked down over the end of her squeezed, pointing tit. Warmth bathed her nipple and made it sprout wildly into his mouth.
His tongue battered the rubbery nub and made her whimper with passion and lust and the illicitness of it.
"Ohhhhh, stop, Whit… don't…" she gasped.
But her body made a mockery of her words. Her hand cupped the back of his head. Her other hand went to her lap and cupped the back of Carla's head, pressing the girl's face more firmly against her sweltering, shuddering crotch.
"Ahhhhhh, God! God!" she cried wantonly.
Her spine arched. Her tit filled her brother's mouth full of the soft, sweet flesh. Her nipple felt ready to spurt something warm and sweet.
Carla's tongue washed up and down the slippery, running gap of her pussy. It circled over her clit again. It rimmed the muscular mouth of her virginal hole and darted inside, probing toward her tautly stretched cherry.
"Ah! At!" she gasped sharply.
When her body wrenched, Whit sucked his mouth from her tit and shot Carla a warning glance.
"Don't pop her twat, damn it!"
Carla didn't respond. But she kept her tongue back, making it circle right at the mouth and press thrillingly against the big muscle there.
Whit leaned over farther and sucked at her other tit, drawing on it, making it into a stiff cone with his squeezing fingers. Monica moaned and tossed, arching her spine shamefully, giving him as much of her swollen, hot tit as his mouth could take.
She had no modesty left now. It had gone too far. All she wanted right then was the sensation they were giving her. Whit had been right. There was nothing to do but enjoy it. She could feel guilty and ashamed later.
Her eyes popped open suddenly. She stared down at Carla's head. She felt her ass being lifted higher from the seat and her legs being forced up and back.
Carla spread her butt cheeks wide. Her tongue licked down her pussy gap and over her vaginal mouth and then kept on going, under the succulent, sensitive under curve of her crotch.
"What – what are you… ohhhh, God! Ohhhhhh, God!"
The wet, velvety tip of her tongue – that's what it was. It had to be that. It writhed and circled. It darted back and forth. It fucked in and out and thrilled her beyond belief.
"Whit – she's fucking my asshole with her tongue!" Monica cried harshly and loudly, right into his ear.
Her body jerked rind shuddered. Her tit swelled into his mouth until he nearly choked on the abundance of it. Heat blazed through her body in wild, licking tongues of flame that shot inward from the torching spark at her asshole.
