"Oh baby, I will!" Alex gurgled, chewing and kissing her tits with ever-increasing ecstasy.
While he began fucking her furiously, slapping her body up and down against the porcelain, Robin grabbed the soap from the soap dish and rubbed the bar against his asshole.
Alex flinched as his sister lathered up his shitter, then began digging her fingers inside the dark, hairy hole. He smacked against her with his full weight, as though trying to get his entire body inside her tight, hot hole.
Robin wrapped her legs around his waist and humped forward, thoroughly impaling her cunt with his stabbing dick. She jammed both middle fingers into his shitter as a thundering spasm of release tore into her guts with violent contractions.
"Slam it in harder!" she cried out. "God, fuck me as hard as you can with that beautiful cock!!!"
Alex felt his sister's convulsing pussy clamp around his stabbing cock like a hot, grasping, greasy hand. The suction of her pussy walls was like a tight, hungry mouth. His prick began to jerk, his cockhead ballooning explosively.
"Take it!" he grunted, smacking into her pussy with brutal, unmerciful jabs. "Take my cum in your tight little cunt!"
The warm water and the hot gushing spurts of jism that pounded into her slit made Robin feel as though she were in a rain of thick, juicy sperm. Her body buckled with tremendous release, the jerking spasms of climax crunching into her guts over and over again.
It was several moments before either could speak. The bathroom was filled with the sound of the shower and their uncontrollable moans. Finally, Alex pulled off his sister and sat down, leaning against the side of the tub.
"Man, I feel like I've been kicked in the ass by a mule!" he whispered, gasping for air. "I never knew cunts like that existed!"
Robin leaned forward after sitting up. She eyed her brother's cum-smeared prick and slipped it between her lips. A renewed hunger burst in her pussy as she drank down the final wads of his explosive climax.
Alex stroked his sister's back, then gently pushed her face against his crotch. It was hard for him to believe, but her hot, sucking mouth inflamed him with fresh, raw passion. He spread his legs so she could nestle between his thighs.
"What did I ever do to deserve this?" he asked. Robin couldn't have answered had she wanted to. Her brother's cock was like a hot poker stabbing into her throat. She couldn't remember having a better, more delicious sensation. Unless it had been with her other brother, Paul.
God, wouldn't it be wonderful to make love to both brothers at the same time! Her body jerked explosively just considering the thought.
"I want it!" she gurgled. "God, I want it, and I'm going to have it!"
CHAPTER EIGHT
Three nights later, Robin got her wish. She could hardly believe what was happening to her. She was lying on the bed, her hands clasping two, delicious long cocks. Paul was on her left, and her other brother, Alex, lay to her right.
"Well, you asked for this, now what are you going to do with it?" Paul asked.
"I really hadn't thought about it," Robin answered, gliding her fingers up the two thick shafts. "Why don't you surprise me."
"Well, until I think of something really original." Paul said, pulling her head down against his crotch, "why don't you suck me a little?"
Robin's eyes lit up. She crawled between his legs, her ass jutting in the air. Grabbing his prick with both hands, she pulled the enormous, blood engorged cockhead into her mouth. She closed her eyes and moaned as she slipped the thick meat deeply into her throat.
Alex watched with fascination as Robin gobbled down Paul's dick. He touched her smooth, rounded ass, and knelt behind her. He nudged his throbbing prick against the frothy, tight opening of her pussy.
"Think I'll get a little of the action too," he said, stabbing forward.
This was exactly what Robin had been waiting for. Two, marvelous cocks poking into her body. She shivered with obvious ecstasy, feeling one cockhead sink into her throat, while the other squeezed into her guts. They were so big and long, they seemed as though they would meet in her stomach.
Paul stretched his legs wide and placed his hands behind his head. He was prepared for a slow, delicious suck-job, memories of his sister's hot mouth flashing in his mind. However, her eager sucking made him realize that this was not what she had in mind.
"Hey, take it easy!" he said. "We've got all night! You're sucking like I was gonna disappear any minute!"
Her brother's voice was a mere rumble, as she ground her nose into his crotch, her lips pursed around the base of his dick. She was totally lost in a world of her own. The throbbing meat in her throat and the hot slab of flesh that dug into her pussy were her only concerns.
"Goddamn, her cunt is tight as shit!" Alex grunted to his brother.
"Couldn't be anything as tight as her mouth!" Paul moaned, as he placed his hands behind Robin's head and pushed her face savagely against his crotch. Her excitement had become infectious. "Christ, baby sister, you are one talented cocksucker!"
Robin began wiggling her ass against Alex's thrusting cock, feeling the slick prod of meat grind deeply into the back of her slit canal. The enormous cockhead pierced between the ring of pussy muscle, inflaming her tissues with a hot, convulsing warmth. The greater the ecstasy in her cunt became, the harder she worked her mouth.
She cried out silently, unable to make even a gurgling sound as the end of Paul's prick jammed into her voice box. Even then, she gobbled eagerly, lapping her lower lip, trying to suck his balls.
Alex threw his head back and winced. Already, he knew control was leaving him, and although he wanted to preserve this moment for as long as possible, his nuts ached for release. He began smacking into his sister's pussy with staccato, stabbing pumps. His nuts slapped wetly against the insides of her thighs.
"Hold on!" he grunted. He squeezed his fingers into the delicate flesh of her hips, jerking her ass back and forth. "Hold… oh… fuck… take it, you cunt!!!"
Although aware of only the deep, hard jabs of stiff cock, Robin was blasted into the reality of Alex's exploding orgasm. The iron-like texture of his prick was immediately bathed in a giant, gushing river of hot, sticky cum. She flinched with a jolt.
"Aaaauuugghmmmff!" she gagged, unable to control even the slightest movement of her body. Thick, splattering waves of climax drilled into her cunt with blasting force. She gurgled out another wet moan, her voice muffled against her brother's mouth-jabbing cock.
Alex's movements became so fierce and violent, his gushing prick slipped out of his sister's pussy. He grabbed his cock with both hands and aimed it back toward the hole. His shaft jerked upward with another hot load of sperm, and as he thrust forward, his cockhead smacked against the tight, tiny shitter opening.
The movement caught Robin totally by surprise. Her cunt was swept in a horrible sensation of being empty, but the pumping rod of prick that squeezed into her asshole more than made up for it. Another rippling stab of climax thundered into the back of her pussy.
Alex would have been more gentle, but he, too, was caught off guard. He withdrew slightly, trying desperately to pound back into his sister's slit, but it was useless. He couldn't have stopped now for anything. He smacked brutally back into her shitter, squeezing the tender, sucking wall of hot muscle to the breaking point.
Robin reached under and grabbed the opening of her cunt with her fingers. She stuck in her middle finger, driving it against her throbbing, orgasm-filled clit. She poked her finger back and upward, feeling her brother's prick through the membrane that separated her pussy and asshole. The sensation made her chew on Paul's dick with raw, unbridled hunger.
