Brother and Sister Are Insatiable

As soon as his parents pulled out of the driveway Saturday morning, Allan made a bee line for his sister's bedroom. Bonnie was naked when he looked in on her so Allan stripped off his clothes and crawled in bed with his sister. He moved between her legs and put his mouth right on her pussy. Bonnie gasped when she felt her brother's mouth cover her vulva and almost screamed out when his tongue penetrated her pussy. Bonnie was overcome by the sensation.

Bonnie shivered and trembled under her brother's hands and kisses. Then she cried out when Allan first swiped her pussy with his tongue. Allan lifted her legs up to his shoulders as he covered her pussy with his mouth. Allan could the feel the firmness in Bonnie's thighs and firm quads. She clamped her legs tightly around her brother's neck as he delved in to her inner depths. Allan located her erect clit and sucked it into his mouth emitting an audible gasp from her. Allan then reached under her and grabbed a hold of her curvy buttocks. Allan loved the firmness of his sister's muscular ass cheeks as she tightened them. Bonnie was really hot and she humped her brother's face as he sucked on her clit. She started to cum and Allan held her thrashing body tight against his mouth. His hands dug into her firm ass flesh as she went wild with her first orgasm of the day.

"Oh, oh, oh God, her it cums," she screamed as her orgasm rocked her body.

Allan held his sister tight and sucked every drop of female love juice from her pussy. Bonnie writhed and gasped all throughout her intense orgasm until finally her climax subsided and her body calmed. Allan licked her tenderly until she couldn't take any more and she gently pushed her brother's head away from her pussy. There was no doubt now as they had become lovers.

"Wow that was incredible Allan. No one has ever eaten my pussy like that before!" she sighed.

Bonnie leaned over and took her brother's cock in her mouth gently nibbling on the cock head. Allan was pleased by his sister's action as she had obviously done this before. Allan fondled her tits as she sucked him deeper in her mouth. Bonnie took her mouth off of his cock long enough to tell her brother that he had a beautiful cock and then she sucked it back into her mouth. Bonnie sucked her brother for awhile longer until she was hot again.

"I am really hot. I need your cock in me Allan," she gasped.

Bonnie lay back in bed and spread her legs as she beckoned her brother to come to her with her arms open. Allan knelt between her thighs and slipped his cock into her pussy. Bonnie closed her eyes and sighed as her brother's rock hard cock entered her. Allan began to fuck her slowly as his cock settled into her snug pussy.

"You feel good in me. I like your big cock in my pussy," she told him.

Allan's cock was all the way in now and Bonnie wrapped her muscular legs around his lower torso. They picked up the pace as they fucked and Allan soon found himself pounding Bonnie's pussy. She pulled her brother into her with her strong legs as he fucked her and they both raced toward their climax. Allan could feel his orgasm building in his balls and he knew it would be a big one. One more thrust and Allan's body tightened as he emptied his balls into his sister's pussy. Bonnie felt the surge of his semen flood her pussy and she fucked even faster in search of her own climax. Bonnie made sure that her clit stayed in contact with her brother's shaft as she raced toward her orgasm.

Bonnie stiffened and cried out that she was cumming as her legs clamped tightly around her brother's body. Her pussy involuntarily squeezed his cock. Allan could feel the vaginal muscles clench and release his cock over and over again until his sister finally went limp under him. They were both sweating from the intense fuck session when Allan rolled to his side allowing his softening cock to slip from his sister's cunt. Bonnie just lay on her back looking up at the ceiling and breathing shallowly.

"Allan you are a good lover. That was a great fuck," Bonnie sighed.

"I would say that you are very good yourself," Allan replied softly.

Bonnie snuggled into her brother and he put his arm around her. He stroked her firm tits and teased her rock hard nipples as they lay together. They didn't say much as they lay together but Bonnie began to stroke her brother's cock and held it lovingly in her hand. Allan started to harden again and she smiled at his response to her fondling. Bonnie slid down her brother's body and took his cock into her mouth again. Allan moved his sister's hips over his face so that he could lick her pussy and they settled into a comfortable 69 position, a favorite of Bonnie's. He caressed Bonnie's incredible ass and teased her nether hole as they ate each other. Allan moistened his sister's asshole with her own pussy juice and his saliva before pushing his finger into her ass. Bonnie accepted the finger in her ass and they ate each other until they both came again and then returned to a side by side position.

Allan got Bonnie out of bed to shower with him wanting to repeat Friday's action. He loved washing her sexy body, soaping her tits, fingering her pussy and her asshole. Allan slipped a soapy finger up his sister's ass and fondled her curvy firm buttocks. His cock was back at attention so he moved behind her and slipped his cock into her soapy asshole. Bonnie grunted as her brother's cock penetrated her lovely ass and she leaned forward to place her hands on the shower wall. Bonnie arched her back accentuating her shapely ass as she leaned forward. The sight was incredible as Allan slid his cock in and out of his sister's beautiful ass. The scene was even more erotic given that they were in the shower and his sister's skin glistened with water. Allan tired to prolong the ass fuck as long as he could but he was so turned on that he came quickly. Allan flooded Bonnie's ass with his seed and she groaned as it filled her anal cavity.

Allan was able to stay hard and he kept fucking his sister's ass even though he had emptied his balls. He fucked Bonnie's ass until his cock softened and slipped from Bonnie's ass and they stepped out of the shower just as the water was starting to turn cold. They didn't dress but instead put on their bathrobes and went down to the kitchen to eat something.

After breakfast Bonnie headed for her bedroom with her brother right behind her. Bonnie stripped off her robe quickly and hopped in her bed. Bonnie was lying on the bed naked as she watched her brother lose his robe and get in bed with her. She watched him as he crawled between her parted legs. He parted them even wider, taking his time to look at her wet snatch in detail. Then he slowly lowered his head, breathing in deeply and smelling her sex. Bonnie could feel his breath on her snatch when he suddenly opened his mouth and licked the length of her slit. Bonnie writhed with pleasure and played with her tits. Allan teased her with his tongue for a while and then he used it to part her pussy lips encountering more wetness. He lapped up her juices and started flicking his tongue across her clit. Bonnie moaned louder and louder as Allan knew exactly how to please her hungry cunt. He sucked on her clit for a while and then he slid his tongue inside her tight hole. He tongue fucked her, faster and deeper, applying pressure to her clit with his nose. Bonnie pulled at the headboard with her hands as she wrapped her legs around her brother's shoulders and thrust her hips up to feel more of him. When she couldn't hold back anymore she cried out loud and her pussy juices showered his face as she orgasmed.

He crawled up next to her and kissed her deeply, sharing the juices with her. Bonnie could feel his cock getting hard against her hips again as he lowered his head and started sucking her nipples. It felt so good. He sucked and bit her tits, pulling them and kneading them. Bonnie was soon on fire again and she wanted his cock so badly.

"Fuck me, Allan," she begged breathlessly.

"That's better," he smiled. "Pull your legs up and open yourself wide for me."

Bonnie did as she was told. She grabbed hold of her legs and pulled them wide apart, showing off her dripping pussy. Allan kneeled by her cunt and jerked his cock, getting it really hard. He ran his cock head the length of her wet slit and then he entered her cunt with the thick cock head and stopped there.

"Oh yeah, baby," he gasped. "You're so hot. I love fucking your cunt."

"Oh yes," she moaned. "Fill me with your thick meat."

With those words he slowly started burying himself deeper inside her cunt. Bonnie felt herself opening up to accommodate his full size and he felt great inside her. This was what a cock was supposed to feel like. This slow, torturous pleasure was what fucking was supposed to be like. When he was buried all the way inside her cunt he stopped, smiled at her and started sucking her tits again. They lay like that for minutes. Her brother's cock was firmly lodged in Bonnie's hungry cunt and he was sucking her nipples. She was impatient to feel more but he refused to move. He was in control of her pleasure.

When he was ready he placed his hands on either side of her to give himself support and then he slowly slid his fuck meat almost completely out of her cunt. Only the tip was still inside her hole and Bonnie moved her hips upwards to get him back. She wanted him to fuck her. She wanted him to fill her again.

"Fuck me, please!" she begged him.

Then he quickly pounded back inside her again. His balls slammed into her ass as he filled her cunt. He pulled out again and slammed back inside. With an ever increasing pace he was burying his cock deeper and harder inside her tight hole. He slammed inside his sister harder and harder and every thrust went straight to her clit, sending an electric shock through her body.

Bonnie was breathing faster and faster. She couldn't believe the pleasure he was giving her. She loved every moment of the fucking. She moved her hips to meet his thrusts, to get as much of his fuck meat inside her. She could hear the sounds of their fucking get louder and her pussy got wetter as her hungry cunt worked overtime to produce more juices. She knew that she wouldn't last much longer.

"I've got to cum," she panted.

"Oh yeah, baby," he whispered against my skin, "Cum for your brother!"

With those words she felt her pussy contracting tight around his shaft. He kept fucking her at the same pace as before while her pussy shivered and convulsed around his thick meat. When she was done cumming he pulled out and put her on her hands and knees. He wasn't done yet. His cock was still big and hard and he was going to get satisfaction from her pussy.

He easily slid his cock into her waiting hole. Bonnie was ready to take his cock again. He managed to get even deeper from behind. He slammed harder and faster now. Each thrust sent his balls crashing into her sensitized clit. Then he pulled her up by her tits and with her full breasts in his hands he nibbled at her neck.

"Your cunt is so sweet and tight, baby," he whispered as he kept pumping into her, hitting her womb with every thrust, "You make me feel so good."

Bonnie's breathing grew heavier and she knew that she was about to surrender to his fucking once more. Her pussy squeezed tight around his cock and her body shook. She moaned out loud and Allan stopped his fucking. With her pussy gripping his cock hard and milking him he thrust deep inside her and roared as he released his spunk into her hungry cunt.

When we'd both stopped cumming he pulled out of her and collapsed next to her on the bed. They were both sweaty from the sexual exercise and he pulled her tight into his arms.

"You are a great fuck, baby," he said and smiled.

She kissed him as she heard those wonderful words. Bonnie straddled him and he guided her brother's cock back into her cunt. She rode him fast and furiously as he played with her bouncing tits.

"God, you're insatiable, Allan. That lovely cock is ready for more." Bonnie gasped.

"Do you mind?" Allan quipped.

"Of course not, do what you like. I'm yours for your pleasure. Anyway you want it." Bonnie offered.

"You're too good to be true. Anything I want?" Allan teasingly challenged his sister.

Bonnie rolled off her brother and got on all fours waving her ass at him. Bonnie raised her butt into a half kneeling posture. She stared at her Allan while she sucked the middle finger of her left hand into her mouth. When it was wet enough she drew a shiny line down her body to her back door. Gently spreading her ass cheeks she wet the puckered hole of her ass and probed her fingertip in ever so slightly.

"I think you I know what you want Allan," Bonnie teased.

"Oh yes I want to be in your ass?" Allan said excitedly.

"Oh yes, Allan. Do it here. Fuck my ass with your lovely cock. You know you want to. And I want you to," Bonnie pleaded

Smiling; Allan knelt behind her on the bed. Bonnie cooed and encouraged him while she smeared her juices from her pussy to her ass to lubricate it in readiness. The large purple head of his dick prodded his sexy sister's asshole and slid across the puckered entrance. Allan first slid his thick cock deep into her cunt to get it moist with her natural juices. Bonnie groaned aloud as her pussy was still very sensitive from the recent fucking. Allan made a few slow strokes and watched as Bonnie poked her finger ever deeper into her bum hole. Soon she was knuckle deep and Allan's prick was slick with her pussy cream. Extracting her digit she looked back and smiled at her brother.

"I'm ready now," Bonnie cooed.

Allan eased his big cock from her pussy and trailed it up to her bum. Bonnie positioned the cock head against her hole and pressed back with her body. Allan matched her movement with a gentle forward push. The very tip of his cock started to enter her tight hole. Bonnie's face was a picture of sexy concentration, her brows pinched and her mouth drawn tightly shut. The big cock eased slowly into her back passage. She relaxed her muscles and slowly welcomed her brother's tool into her most private place. Eventually it is in all the way to the hilt and Bonnie looked back at her brother and smiled

"Are you okay baby?" Allan asked concerned.

"Yes but put some more lube on it and fuck me but do it really slow," She requested.

Allan grabbed the lube off the nightstand and squirted on his exposed shaft. She clearly loved the solid feeling in her ass as he re-entered her. Bonnie rubbed her clit, which served to drive her to another orgasm. There was sweat on both their bodies as Allan held his sister's waist and slid his dick in and out of her now gaping asshole. He was admiring her ass and he couldn't believe that he was fucking his sister's ass once again.

Bonnie's attentions on her pussy were having the desired effect and she was nearing another orgasm. She hoped that they could climax together so she told her brother she was going to cum.

"I am too baby, very soon," Allan strained to talk.

His pace quickened again and he changed to shorter faster strokes. He was pumping her hole telling his sister that he would soon cum. She was gasping, grunting and straining toward her own orgasm. Faster and faster her fingers flew over her clit. Her body started to convulse with a powerful orgasm. At the same time Allan came, he jammed his cock into her ass to the hilt and felt it as it jerked and spewed his spunk deep into her anal passage. He fell forward on top of his sister with his cock still buried in her and still twitching and spitting its cum coating her anus.

Bonnie's orgasm matched her Allan's in length and fury. Surge after surge of pleasure shot through her body and each new wave was triggered by each new twitch from her brother's exploding cock. The two of them lay together and cuddled on the bed with her brother's cock still twitching in her ass. Eventually Allan went soft and his cock slipped from his sister's curvy ass. The two of them stayed in bed for another hour caressing and playing with each other. They would have to figure something with their schedules so that they could somehow continue their incestuous affair but for now they enjoyed their time together.

Bonnie and Allan were sitting in the family room eating pizza and watching TV when their parents got home. It was as if everything was normal at the house and the parents went about their routine. The family wrapped up the night talking and watching TV all the while Allan was thinking about when he might hook up with Bonnie again. The best time was after school but he had some late classes he had to deal with. Once summer break arrived in two months Bonnie and Allan would have a lot of time together but until then they would have to be careful at home.
