His balls drew up tightly under his crotch and pumped. Sperm hosed and boiled from the tip of his prick, shooting far up her silken depths and bathing her spasming cervix.
There was so much of it her pussy tunnel wouldn't hold it all. It spurted from between her bloated, quivering cunt lips and ran down the bottom of her crotch, puddling in the upturned little mouth of her quivering asshole.
Monica stood outside and watched her brother's asscheeks clench together tightly as he shot his big wad into the girl's spasming pussy.
She felt her own cunt blaze with heat. She remembered the feel of Burke's big prick rubbing up and down her silky slit and rippling over the throbbing bud of her clit, and the squeezing sensation her hands were giving her pussy on the outside of her pants wasn't enough.
She gasped repeatedly, unable to take her eyes from the erotic sight. She thrust her hand inside her stretch pants and felt the wet curls of her pubes, the bloated, shaking lips of her virginal twat.
One hand wasn't enough. She shoved the other one inside her pants too, and the material cupped her asscheeks tightly. She spread her puffy cunt lips with two fingers and ran another one up and down her leaking slit, pretending it was Burke's jumping cock again.
Her pussy was drenched with slippery juice. Her fingers squished and slopped through it and made a lewd noise she was sure they could hear inside.
She watched the way Carla hugged and thrashed and shuddered. She listened to the girl's cries of sexual bliss. She looked at the expression on the pretty face.
It looked as if she were in terrible pain, the way her features were all twisted up and yells came out of her open mouth, but that was the only indication of pain there was.
Her pussy was wide open and accepting. She strained upward as if unable to get enough of Whit's cock up her pussy. Monica knew she wouldn't act that way about fucking if it was hurting her.
It sure wasn't hurting Whit. He bore into her cunt with every last millimeter of his bucking prick, and his sperm spewed and overflowed from the silk-lined hole.
Monica's clit throbbed and burned as the friction of her slippery finger became nearly unbearable. She felt that great hollow feeling start in her belly again, and she knew she was going to come.
She felt another kind of emptiness – the kind you feel when you know you've passed up an opportunity you shouldn't have.
It was clear as hell from watching Carla and her brother that fucking didn't hurt. She wished fervently right then that she'd let Burke fuck his big prick into her pussy and blast his sperm there instead of onto her belly.
"Eeeeee, God! God!" Carla nearly screamed, giving a final lunge upward as the biggest wave of all hit her.
"Ah! Ah!" Whit gasped, collapsing on top of her with a final shake and clench of his ass.
Monica nearly cried out with them. But she clamped her lips together tightly and kept the scream bubbling up in her throat to a muffled squeal.
Her pussy sucked and spasmed. Her legs shook. She leaned against the side of the building and let her body shudder violently as she came and came.
Her juice flowed from her virginal hole in a stream. She pressed the tip of her finger over the very mouth of her vagina and felt all the young muscles there quivering and sucking, as if trying to draw her finger inside her hole.
Ohhhhhh, Burke! she cried inwardly. I want your cock flecking up my pussy right now!
When her emotions had stopped spinning, she kept her fingers curled around her twat. The meat there was still quivering, still terribly sensitive.
She heard them gasp and moan inside, and she put her eye to the crack again to see if they were fucking another time.
Whit's prick was still buried to the hilt in Carla's pussy. Her legs were over the edge of the bed, now, her feet on the floor. She was licking his ear, thrusting her tongue tip from between her lips and giggling, making him shiver again and again.
"Ready for another one, honey?" she teased him. "You've got nine more big comes to go to make your big brag."
"In a minute, baby," Whit gasped. "Whew, what a wild, wet cunt you've got!"
"Minute, hell," she moaned. "I'm ready now, honey! Ohhh, don't make me wait for it – fuck me!"
He lifted his head and looked at her. "That's crap," he said. "Baby, you can't be ready after an explosion like that."
"Ohhhhhh, fuck me," she groaned, closing her eyes, twisting her body under him, lifting her hips up and down again.
"You're putting me on!" Whit moaned, wincing a little as if it did hurt him this time.
"Watch me, honey," she said, opening her eyes, looking at him with a hungry, wild expression. "Take that useless cock out of my pussy and watch me, and I'll show you if I'm putting you on!"
She pushed at his chest. Whit lifted up on shaky arms. His prick slid from her sodden hole. It was half limp. A string of sperm stretched between the wide eye and her pussy flesh. It glimmered in the light and then sagged and broke, leaving a little drop on the tip of his shiny, wet prick.
