Monica nearly sobbed. She'd never felt so pressured and miserable in her life. She looked at Carla's flaring, weaving butt and imagined Burke's steely hard cock fucking into her body instead of up her virginal pussy, and she shuddered with agony.
She stared at the fleshy, firm expanse of ass, and her fingers trembled. Hell, it wasn't going to bite her. It was just a girl's butt. It would feel just like her own butt. And it might be kind of interesting to see what another girl's hot pussy felt like. She certainly knew what her own felt like.
Her fingers trembled over the smooth, rounded globes of Carla's shaking butt. She heard the girl moan. She heard her brother moan shortly after when Carla sucked his pulsing prick into her hot, wet mouth again.
Monica felt the ass all over. It was not as hard and tight as her own. It was a little broader. There was a yielding quality that hers didn't have yet.
Her fingers dipped into the deep cleft, and she felt Carla weave her butt appreciatively and heard her moan.
"Ohhhh, yes, sweetie! Do it!" she gasped. "Deeper! God, go deeper! Right to my asshole! Ohhhh, put your finger on my asshole and jiggle it!"
Monica felt overcome with emotion. There was a strange power she felt she had now, a kind of dominance that was thrilling. Her fingers stopped trembling. Instead, they swept boldly up and down the deep crack between Carla's cheeks.
She felt the puckered, pulsing, pink-brown anal mouth under her fingertip. Carla gasped sharply and drew on Whit's prick harder and let her spine arch as much as she could in her cramped position.
Her ass angled upward, and her thighs pressed firmly against the edge of the seat as she spread them as wide as she could. Her little asshole pulsed in and out as if kissing the tip of Monica's finger.
"Ahhhhh, God! That's good!" she cried. "Ohhhhh, do more, sweetie – do more, and I'll really take care of you!"
Monica sucked in her breath. She didn't know what Carla meant by that. Was she planning on tickling Monica's ass too? Or was there something more. Monica had no idea. She'd been so sheltered all her life she wouldn't even have known there were any variations to fucking, if she hadn't watched Carla and her brother the other night.
Monica twirled her fingertip about the rubbery asshole and felt the kicking and weaving her touches elicited. Daringly, she slipped her fingers lower along Carla's crotch, and they were suddenly bathed with hot, oiled silk.
"Ahhhhhh, yes!" Carla cried.
Monica felt her head swimming. She couldn't believe this was really happening, that she was touching another girl's pussy. But her fingers sucked and slopped through the wet meat, testing, exploring, feeling every fold and flap and puffy mound of pussy meat.
Carla's clit was big and long. It was nearly like a little prick. Monica reached far under and stroked it with her seeing fingers, and she felt the hard little organ tremble and pulse.
"Ohhhhhh, fuck my cunt!" Carla gasped.
"Quit moaning so damn much and suck!" Whit groaned, reaching for her head and bringing her open mouth back over his cock.
The car was barely crawling down the empty road now. Whit's eyes were closed half the time. It was lucky the road was straight so that he didn't have to steer.
His hips pumped up and down in the seat. He fucked his prick with short strokes in and out of Carla's pursed lips. The fly of his pants was soaked with her saliva as she sucked and drooled and licked him all over, snaking her tongue into the gap to lick at his balls and the root of his trembling prick.
Monica's thighs scissored up and down, and the heel of her free hand pressed rhythmically into her lap, both motions massaging her straining, throbbing clit.
Her body was at a high pitch of tingling and heat, but she knew she wasn't going to be able to come without swirling her fingers over her pussy and really giving herself a good job.
But first, she wanted to take care of Carla. Her pussy was fluttering and grasping at Monica's fingers, trying to suck them up into her hot, wet hole.
Monica sloshed through the wet folds of puffy, drenched pussy meat and felt the trembling muscle right at the mouth of Carla's cunt. She put her fingertip inside.
Hot silk enfolded her finger. The big muscle clamped and nipped and pulled. Carla lifted her head again and shook her hips and ass and moaned.
"Ohhhhhh, deeper! Fuck me deeper! All the way up my cunt!"
Monica sucked in her breath. Her hand was angled around the flare of round ass so that her thumb was in the deep cleft while her fingers were playing at the mouth of the shuddering pussy.
She pushed forward with her hand. She hadn't meant it to happen, but her thumb suddenly slipped into the tight, clamping, quivering asshole and was surrounded by clinging darkness.
"Ahhhhh, God!" Carla cried sharply. "Yes! My cunt and my ass both! Fuck them both! Ohhhhhh, you darling! God, I love it! God, I'm going to pay you back in spades! Ahhhhh, Whit – your sister's going to make me come! Whit! Whit, your prick! Give me your big prick! Fuck – suck! Ahhhhh, God!"
