Aliens Use Sex to Invade Humans Ch. 04

Over the next 24 hours Shelia had sex with her son, her ex-husband and Butch continuously. Some times she had three cocks in her at the same time. Other times Shelia had sex with Aaron alone or with her son. Billy was only comfortable fucking his mother in the ass or letting her suck his cock. Butch agreed to fuck her pussy to see if he could and he was able to remain hard and cum in her pussy. Shelia was thrilled because now she could have Butch in her pussy and Billy in her ass and they were all able to cum. Shelia still sucked her son's cock while they fucked each other in the ass. Shelia had waited a long time for sex since her divorce and now she had more than she would ever have imagined.

Aaron balanced his time between Shelia and the boys. There were times when he just fucked the boys and let them suck his cock. Other times he was with Shelia and he would cum in all three of her orifices. And at other times the four of them all had sex together. Sheila didn't want to leave the house as she loved the attention she received from the three large cocks but she eventually had to go home and the boys had to go back to college. Sheila knew she would be back to sample more of her husband's renewed huge cock.

Aaron was still curious about the changes that happened to his body and others when he had sex. He decided to call Rachel, Sam and Carl to learn what they were experiencing. If they were having similar experiences, Aaron decided that he would contact NASA and report the unusual behavior.

CINDY AND HER FATHER

Cindy always slept in the nude and many a morning her hands would travel over her body caressing her tits and fingering her pussy as she reflected on her boyfriend. Sometimes Cindy got carried away and she moaned softly as she made herself cum. Her actions did not go unnoticed. Her father Mike was usually awake when he heard his daughter's moaning from time to time. One morning he was awake earlier when he decided to look in on his daughter. He quietly opened her bedroom door and stared at her fabulous naked body. Mike was very turned on by his daughter's nakedness and found himself desiring her. Over the past few weeks, he would watch her for longer periods each time and then head back to his bedroom to jerk off while fantasizing about fucking his daughter. Mike would go to his daughter's room right after his wife left for work so that he could spend more time looking at his naked daughter.

Mike began to get bolder and bolder with each visit to his daughter's room. As he watched his naked daughter in bed he began to stroke his cock. He had gotten to the point where he didn't return to his bedroom to jerk off but he stayed in his daughter's room and ejaculated there. One morning Cindy realized that her father was in the room and she made believe she was still sleeping. She peeked through her half closed eyes and watched her father masturbate as he looked at her body. Cindy was pleased that her father was turned on by her naked body and that he would cum just from looking at her.

Cindy looked forward to the morning visits from her father to look at her naked body. She became to tease him relentlessly as she faked being asleep and having erotic dreams. Cindy would roll over on her stomach so that her father could see her ass then she would roll on her back and open her legs so he could see her pussy. Cindy made believe she was dreaming and ran her hands over her body moaning as she caressed her tits and stroked her vulva. Mike was going mad as she watched his daughter and his hand flew over his cock. Cindy rolled over on her stomach and lifted her hips off the bed slightly as she fingered her pussy. Her father went wild looking at his daughter's undulating ass.

The morning after her torrid sex with her boyfriend Ricky, Cindy took it one more step as she fingered her pussy, "Oh yes fuck me," she whispered loud enough for her father to hear.

That did it for Mike he simply had to have his daughter. Mike stripped off his clothes and crawled in bed with his daughter. He moved between his legs and put his mouth right on her pussy. Cindy gasped when she felt her father's mouth cover her vulva and almost screamed out when his tongue penetrated her pussy. Cindy was overcome by the sensation. Cindy shivered and trembled under her father's hands and kisses. Then she cried out when Mike first swiped her pussy with his tongue. Mike lifted her legs up to his shoulders as he covered her pussy with his mouth. Mike could the feel the firmness in Cindy's thighs and firm quads. She clamped her legs tightly around her father's neck as he delved in to her inner depths. Mike located her erect clit and sucked it into his mouth emitting an audible gasp from her. Mike then reached under her and grabbed a hold of her curvy buttocks. Mike loved the firmness of his daughter's muscular ass cheeks as she tightened them. Cindy was really hot and she humped her father's face as he sucked on her clit. She started to cum and Mike held her thrashing body tight against his mouth. His hands dug into her firm ass flesh as she went wild with her first orgasm ever from oral sex.

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

Mike held his daughter tight and sucked every drop of female love juice from her pussy. Cindy writhed and gasped all throughout her intense orgasm until finally her climax subsided and her body calmed. Mike licked her tenderly until she couldn't take any more and she gently pushed her father's head away from her pussy. There was no more pretending now as they both became lovers. Then Mike felt the strange feeling pass through his body as the alien had invaded him through his daughter's nectar.

"Wow that was incredible Daddy!" she sighed.

Cindy leaned over and took her father's cock in her mouth gently nibbling on the cock head. Mike was a little surprised by his daughter's action but she had obviously done this before. Mike fondled her tits as she sucked him deeper in her mouth. Cindy took her mouth off of his cock long enough to tell her father that he had a beautiful cock and then she sucked it back in her mouth. Cindy sucked her father for awhile longer until she was hot again. Mike was stunned as he watched his cock grow to new dimensions.

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

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

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

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

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

"Daddy you are a good lover. That was a great fuck," Cindy sighed.

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

Cindy snuggled into her father 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 Cindy began to stroke her father's cock and held it lovingly in her hand. Mike started to harden again and she smiled at his response to her fondling. Cindy slid down her father's body and took his cock into her mouth again. Mike moved his daughter's hips over his face so that he could lick her pussy and they settled into a comfortable 69 position, another first for Cindy. He caressed Cindy's incredible ass and teased her nether hole as they ate each other. Mike moistened his daughter's asshole with her own pussy juice and his saliva before pushing his finger into her ass. Cindy seemed to accept the finger in her ass and they ate each other until they both came again and then returned to a side by side position.

Mike got Cindy out of bed to shower with him. He loved washing her sexy body, soaping her tits, fingering her pussy and her asshole. Mike slipped a soapy finger up his daughter'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. Cindy grunted as her father's cock penetrated her lovely ass and she leaned forward to place her hands on the shower wall. Cindy arched her back accentuating her shapely ass as she leaned forward. The sight was incredible as Mike slid his huge cock in and out of his daughter's beautiful ass. The scene was even more erotic given that they were in the shower and his daughter's skin glistened with moisture. Mike tired to prolong the ass fuck as long as he could but he was so turned on that he came quickly. Mike flooded Cindy's ass with his seed and she groaned as it filled her anal cavity.

Mike was able to stay hard and he kept fucking his daughter's ass even though he had emptied his balls. He was now able to manage back to back orgasms without losing his erection. He fucked Cindy's ass until he came again. It took a while before he came again and he was able to savor the incredible sight of his cock sliding in and out of his daughter's marvelous ass. Mike's cock softened and slipped from Cindy's ass and they stepped out of the shower just as the water was starting to turn cold.

They went back to be and Mike couldn't believe his renewed capacity for sex or his daughter's insatiable sexual appetite. She watched as 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. Cindy could feel his breath on her snatch when he suddenly opened his mouth and licked the length of her slit. Cindy writhed with pleasure and played with her tits. Mike 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. Cindy moaned louder and louder as Mike 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. Cindy pulled at the headboard with her hands as she wrapped her legs around her father'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. Cindy 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. Cindy was soon on fire again and she wanted his cock so badly.

"Fuck me, Daddy," she begged breathlessly.

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

Cindy did as she was told. She grabbed hold of her legs and pulled them wide apart, showing off her dripping pussy. Mike 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. Cindy felt herself stretching 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 father's cock was firmly lodged in Cindy'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 Cindy 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 daughter harder and harder and every thrust went straight to her clit, sending an electric shock through her body.

Cindy 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 wetter and 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 daddy!"

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 my 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. Cindy 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 me, hitting her womb with every thrust, "You make daddy feel so good."

Cindy'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 Mike 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 straight up 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. Cindy straddled him and he guided her father's cock back into her cunt. She rode him fast and furiously as he played with her bouncing tits.

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

"Do you mind?" Mike quipped.

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

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

Cindy rolled off her father and got on all fours waving her ass at him. Cindy raised her butt into a half kneeling posture. She stared at her daddy 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 daddy," Cindy teased.

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

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

Smiling Mike knelt behind her on the bed. Cindy 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 daughter's asshole and slid across the puckered entrance. Mike first slid his thick cock deep into her cunt to get it moist with her natural juices. Cindy groaned aloud as her pussy was still very sensitive from the recent fucking. Mike made a few slow strokes and watched as Cindy poked her finger ever deeper into her bum hole. Soon she was knuckle deep and Mike's prick was slick with her pussy cream. Extracting her digit she looked back and smiled at her father.

"I'm ready now," Cindy cooed.

Mike eased his big cock from her pussy and trailed it up to her bum. Cindy positioned the cock head against her hole and pressed back with her body. Mike matched her movement with a gentle forward push. The very tip of his cock started to enter her tight hole. Cindy'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 father's tool into her most private place. Eventually it is in all the way to the hilt and Cindy looked back at her father and smiled

"Are you okay baby?" Mike asked concerned.

"Yes! Fuck me but do it really slow," She requested.

She clearly loved the solid feeling in her ass. Cindy rubbed her clit, which served to drive her to another orgasm. There was sweat on both their bodies as Mike held his daughter'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 daughter's ass again.

Cindy'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 dad she was going to cum.

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

His pace quickened again and he changed to shorter faster strokes. He was pumping her hole telling his daughter 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 Mike 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 daughter with his cock still buried in her and still twitching and spitting its cum coating her anus.

Cindy's orgasm matched her daddy'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 father's exploding cock. The two of them lay together and cuddled on the bed with her father's cock still twitching in her ass. Eventually Mike went soft and his cock slipped from his daughter'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 out so that they could somehow continue their incestuous affair but for now they enjoyed their time together.
