Her brother! She was watching her brother fuck his prick into a girl's pussy!
She couldn't help the comparison her mind made – Carla's big, fleshy, wet cunt and her own tight, virginal little slit. Carla's big pointed tits that jiggled to the sides and her own firm, round balls, high and pert.
And she couldn't help but notice the difference between her brother's prick and Burke's. Carla was moaning for the big cock that was sliding up her open cunt, making quite a fuss over it. Monica couldn't help a smug feeling. Her brother's prick wasn't as thick or as long as Burke's had been.
"Ahhhhh, God! Darling, it's all the way up my cunt! Ohhhhhh, what a fucker you are! A big bold fucker! God, take me into the bedroom and lay me out and pump that heavy cock in and out of my drooling cunt and make me come, Whit!"
She screwed her hips around, swinging her round ass in his cupping hands, making her pussy mouth suck and slobber along the stiff, imbedded shaft.
She twisted her chest against him and made her pointed tits slide and flatten against him. She flexed her thighs and made her pussy lift up and down along his cock. And all the while, she nibbled on his ears and his lips and breathed passionately against his neck and face and moaned.
Whit turned, balancing her weight on his forward-thrusting hips. He was grinning broadly, his lips quivering with passion and a feeling of regal power, as if the piece of ass he was holding in his hands was really the whole world.
Monica held her breath again as they staggered back through the doors into the bedroom. Carla's foot caught the edge of the door and pulled it partly closed, allowing Monica to be able to see clearly through the crack it made with the frame.
She watched her brother pump his prick rapidly into Carla's pussy for a moment. He held her cheeks wide apart, and his butt flew back and forth as he stroked her and made her cling to him and moan shakily.
"Ohhhhhhh, you fucker! You big fucker! God, Whit, you're going to make me come already! Ahhhhh, put me on the bed and pour it to me!"
Monica sucked in her breath and glued her eye to the crack. She felt her pussy squirm and shiver and her lips bloat. She slid her hands down her tummy and cupped her burning, quivering crotch tightly with them, pressing her arms in at the sides of her tits.
Whit carried Carla to the foot of the bed. He bent over with her and laid her on her back, still standing. Her legs were still wrapped around his hips, and they came uncurled and flew straight into the air.
"Eeeeee, fuck me!" she cried gleefully.
Whit pounded against her saddle, driving his prick in and out of her split pussy, making her juices spray to the sides and coat her inner thighs and his belly.
Monica watched her brother's balls swing under his crotch. They spanked into the split crack of Carla's ass. Her anus pulsed and sucked, and her cheeks quivered with each slap as if trying to capture his balls in their firm grip.
Whit stiff-armed the bed while he fucked, looking down at her shaking, jiggling tits. He leaned forward and sucked the end of one of them into his mouth and drew on it.
The nipple stretched and popped from his lips, and her tit end gleamed and throbbed. He did it to the other tit, and Carla groaned with sexual bliss.
"Suck my tits!" she cried. "Fuck my pussy! Ahhhhh, you horny fucker, fill my aching cunt with hot cum! Make it boil up my pussy until my belly sloshes!"
"Ohhh, you hot bitch!" Whit groaned. "You love fucking! God damn it, baby, tonight's the night!"
"Ohhhhhhh, yes! Yes! I'm hot enough, Whit – are you?"
"God, yes!" he gasped.
"Then give it to me! Give me the first one, you fucker! I'll bet you don't make the other nine!"
"Like hell!" he cried. "You're the one who isn't going to make it to ten, because your pussy's so hot and wet right now it's going to blow apart with the first one!"
"Ahhhhhh, God! Yes! Now! Right now, you fucker! Blast me full! Here it comes! Here comes – number… one… Yaaaaaagh!"
Her ass lifted high, driving her gobbling, sucking cunt mouth up the jerking tube of his prick. The wet flesh quivered and pulsed, the muscles surrounding her pussy orifice stripping the sensitive underside of his cock as they pulsed with her orgasm.
She flung her arms around his neck and pulled him down against her tits. The pointed cones flattened and stabbed into him, and she shuddered wildly, tossing her cupped ass in his hands.
"Ahhhhhhgh, your cunt! It's eating my cock alive! Ahhhhhh, God, here it comes, baby! The whole flood! Take it! Take it! I'm going to… Ahhhhrrrgh!"
He drove his body against hers, splitting her already spread thighs wider. He pulled upward with his hands, lifting her ass from the bed and wrapping her sucking, silky pussy meat up around the root of his bucking prick.
