Desc: Fantasy Sex Story: Chapter 1 - Billy is driving home from college when a bright blue light blinds him. The next thing he knows, he wakes up on a silver table and life as he knows it will never be the same. His DNA is merged with alien DNA and he becomes much more powerful than he could ever imagine.

It was 6:00 PM and Billy was driving home from college for the Christmas break. This being his senior year, he was looking forward to being at home with his family. It had been almost 2 months since he'd been home so he was really looking forward to spending some time with his mom and little sister.

He just pulled off the interstate, when suddenly there was a huge flash of extremely bright light coming directly at him. The next thing he knew he was waking up on a long metal table. He noticed he was in the middle of a large room with weird bluish white lights shining down upon him. He had no idea of what happened or how he got there. Before he could get his bearings he fell back to sleep.

A short while later and thinking he was dreaming, Billy noticed a tall, lean, white, shadowy figure approaching him as he lay on his back, flat on the table. Fearing for his life, he tried to get up and run but couldn't move. Still thinking he must be dreaming, Billy tried to wake himself up but was unable to do so. The shadowy figure hovered above him and slowly descended until it was barely touching his bare skin.

When the shadowy figure touched him, Billy began to relax and his fear subsided. He had a surreal feeling come over him when he heard the sweetest and most striking voice in his head. "Close your eyes and relax, friend. I'm not here to hurt you, only to bring you pleasure. Sleep my friend, sleep."

Billy's eyes closed and he started to dream. At least he thought it was a dream. In his dream, he was walking through a flowery maze until he came upon a small log cabin. He walked up and knocked on the door but there was no answer. Looking through the front window, he saw a gorgeous woman lying on a bed and she as naked as the day she was born. When she saw him standing there, she motioned for him to come to her.

As he slowly entered the room, he suddenly noticed he was naked also. His cock was painfully hard and bobbing up and down in front of him. When he looked down and saw the size of his hard prick, he knew he had to be dreaming. His cock looked absolutely huge. It wasn't like he had a small cock before the dream, it just wasn't huge. The closer he came to the woman, the more he desired her. Her beauty was beyond compare and her scent was intoxicating. He somehow knew she would fulfill his every desire. Somewhere in the back of his mind he felt this was more than a dream but did not care.

As he climbed up on the bed, his dream partner pulled him to her and kissed him passionately. Her lips tasted like nectar from the gods. He began to kiss the nape of her neck as she grasped his hard cock and aimed it towards her leaking love canal.

With his first push inside, he could feel her velvety pussy gripping his cock like a vice. Her pussy was extremely tight and soaking wet. He felt as though her pussy was made especially for his cock.

He began fucking his dream lover with a passion he'd never had before. He slammed into her tight slick pussy feverishly. With each hard thrust she would moan and her body would thrash about on the bed. He was enjoying himself deliriously. He'd had sex with a few women before but it never felt as glorious as what he was feeling now.

His stamina was usually very good but he was setting such a blistering pace today, he knew it wouldn't be long before he came. Every time he tried to slow down his pace, his dream partner would spur him on by gripping and releasing his cock with her cunt muscles. She was driving him insane with lust.

Neither of them spoke a word as they lost themselves in this moment of unbridled desire. This secretive moment would stay with them forever. They would become a part of each other for the rest of their lives.

Suddenly; Billy's dream lover spoke. "Make me the happiest woman in the universe, make me pregnant. Give it to me! Give it to me now!"

When her pussy started gripping and releasing fast around his cock, he could hold out no longer and screamed! "Oohh my godd I'm Cumming!"

Slamming his cock as deep as he could into her spasming pussy, he shot load after load of hot cum into her steaming hot love canal. He held himself absolutely still, ensuring that none of his sperm leaked out of her baby maker.

His dream lover looked into his eyes and said. "Our task is done, we are joined together forever."

Before Billy could ask her what she meant, he inexplicably fell off into a deep sleep.

Billy didn't know it but her pussy actually was made for his cock. He was having sex with an alien from the planet Altrusay. They could shape themselves into any form they wished. The males in of their species had become sterile after a huge meteor shower on their planet.

The Altrusans had come to earth in search of a human with a special genetic anomaly. Only a human with the right genetic anomaly could save their planet. It just so happened, Billy was the only human male they were able to find with the right genetic anomaly.

Their plan was to merge their DNA with human DNA. They were able to do this because their intelligence was much more advanced than that of the human race. When a female of their species had sex with a human, their DNA's would merge. Once the merger was made, the female alien would then spread the human DNA to the males of her species. The new DNA would expand throughout their Planet and their species would survive.

The same scenario would then occur with the human male. This would result in a merger of the two different species. When the Altrusan female's DNA merged with the male human's DNA, the alien's extremely powerful pheromones and high sex drive would also be passed along. While the Altrusian's only had to exchange fluids for a DNA transfer, Billy would have to impregnate a woman with the same genetic anomaly as his in order to complete the transfer.

Their plan had two flaws.

Their first flaw was that they did not take into account the high amount of pheromones their bodies secreted or the high sex drive of an Altrusan male.

A young Altrusan male was able to copulate 10 to 20 times a day. Whereas, a young human male would never be able to keep up that pace. After each conquest he would need time to recover. Even though he might want to have sex as much as an Altrusan male it would still be impossible.

Their second flaw was he would only be able to impregnate women with his same genetic anomaly. Unfortunately there were only 8% of the women on earth had this genetic anomaly.

With his new DNA features, no woman on Earth would be able to resist Billy. There would be women attracted to him everywhere he went. The Altrusans could only hope there were enough women within his local area to begin the merger.

When Billy woke up, he was sitting in his car parked in his mother's driveway. He thought. "What the hell? How did I get here? What the fuck just happened?"

The last thing he remembered was getting off the interstate then suddenly he was home. He looked down at his watch and noticed only 20 minutes had passed since he got off the interstate. He knew it took at least 1 hour to get home from that point. How in the hell did he get home so fast?

Shaking his head, he decided to try and figure out what happened later. Now, he needed a shower badly. He reaked of sex.

Scratching his head, he finally went inside. He thought to himself, 'How can I smell of sex? The last time I had sex was with Christie Anderson last week. What the fuck is going on?'

Upon entering the kitchen he noticed a note his mother (Sally Reynolds) left for him. The note said. "Shelly and I had to go to the grocery store. We'll be back shortly. Love, Mom."

He went upstairs and started taking a shower. He was enjoying the warm pulsating spray flowing down his body when his cock began to harden. Just as he started to stroke it there was a sudden knock on the bathroom door.

Startled, Billy asked, "Who is it?"

The door opened and a woman's voice told him. "It's just me Billy, Aunt Evelyn. I saw your car parked in the driveway and thought I would pop in and say hi."

Evelyn Langley lived next door. She was Billy's mother's best friend. They went to high school and college together. She wasn't really his aunt but for as long as he could remember he called her Aunt Evelyn.

Evelyn was a knockout. She was in her mid forties, had long blonde hair and the smoothest, longest legs of any woman he'd ever seen. Still, it was her breasts that Billy loved the most, her large breasts enhanced the rest of her body perfectly. She had been the object of quite a few of Billy's masturbation sessions.

Billy poked his head out from around the shower curtain and said. "Hi Aunt Evelyn, just give me a few minutes and I'll be out of the shower. We can talk then."

She was about to answer Billy when she smelled a strange heady odor. It was very intoxicating. Her body began to react to the smell almost immediately. Her nipples hardened and her pussy began to drench her panties. She was being drawn to the shower.

Billy did not notice his Aunt Evelyn undressing while he finished his shower. He was about to emerge from the shower when all of a sudden Evelyn stepped inside with him.

"What the hell? Aunt Evelyn, what are you doing?" Billy exclaimed!

Placing her index finger to his lips, Evelyn whispered. "Shhh, don't worry about a thing. Auntie Evelyn is going to take good care of you."

Before Billy could speak she grabbed his cock roughly and kissed him hard on the mouth. Billy could not believe his luck. The woman he fantasized about since he was a teenager, was kissing him in the shower and playing with his cock.

Billy broke away from their kiss and went straight to her mountainous tits. He took one in his mouth and began tweaking the other nipple between his fingers. It took no time before he knew his actions were having the desired effect he was looking for. She was moaning loudly and begging him to fuck her.

Evelyn had never thought of Billy in this way before. She always felt as if he was the son she never had. She would do anything for him. Right now though, he had her pussy flowing like a river and she wanted him to fuck her in the worst way imaginable. A sudden picture flashed in her mind of Billy pinning her against the shower wall and violently fucking her in the ass. She gasped at the thought because she loved being dominated.

Dropping to her knees she began thoroughly sucking his cock. She thought, 'Damn he tastes good. I should've done this years ago.'

Billy could not believe his eyes. His beautiful aunt, his mother's best friend, was on her knees before him sucking his cock. His dream had finally come true.

If there was one thing Evelyn was good at in her life, it was sucking cock. She was a pro's pro. She started working her way up and down the shaft of his rapidly growing cock. Every time she reached its engorged head, she gently scraped her teeth across it. Every now and then, she would playfully bite his scrotum. She knew the very top of the head was one of the most sensitive areas on a man's cock, especially right after he came. She had driven many a man crazy using this technique before. There wasn't a man alive who wouldn't want her sucking his cock.

Billy knew if he didn't stop her soon, he was going to blow his load down her throat. Pulling her up from his cock, he picked her up and tried to slam his cock into her inviting pussy. His over exuberance was causing him to miss the target.

Realizing Billy was too excited, Evelyn grabbed his huge cock and aimed it at the entrance of her hot dripping pussy. Pressing her against the shower wall, Billy gave one big shove and buried his massive cock deep into her fiery hot cunt.

Evelyn gasped out loud as he stuffed her pussy full. His cock felt even bigger in her pussy than when she had it in her mouth. Without warning, he started slamming his cock into her hard and fast like a well oiled piston. With each hard thrust, he hit her G spot. The pleasure Billy was giving her was so intense, she had to bite down on his shoulder to keep from screaming out loud.

Billy kept driving his cock into her slick twat hard and fast. Realizing his dream was coming true, he had to make sure she would want to fuck him again and again.

He thought. 'A chance like this comes around once in a lifetime. I better make sure she remembers it.'

Evelyn felt as if he might drive her through the shower wall he was fucking her so hard. She knew her back was going to hurt her tomorrow but could care less. She needed the monstrous fucking he was giving her.

It had been almost two years since she been laid. She picked up some young stud the night after she signed her divorce papers. The sex was good but didn't compare to the fucking her Billy was doling out.

She started flailing around so hard it was all he could do to keep his cock in her pussy. Billy knew from her reactions she was close and he wanted to cum with her.

After steadying her against the shower wall, he slowed his pace. He began to slowly withdraw his cock almost all of the way out of her slick twat, then just when she thought his cock would flop out of her, he would drive it back into her hard and deep. 1,2,3,4,5,6,7,8, he began counting to himself.

When he reached 9, she started shaking uncontrollably and flooding her juices all over his mighty cock. Her orgasm hit her like a tidal wave. She became lost in ecstasy, never before had she been so thoroughly fucked.

Evelyn bit down on his shoulder and screamed into it. "Yes, oh shit, oh my god, so good! Please Don't stop"

The instant she started cumming, Billy's cock blasted the walls of her hot cunt with squirt after squirt of his alien seed.

He exclaimed! "Aunt Evelyn, oh no I can't believe it, I'm cumming in your pussy! Ieeeeeeeee!"

Evelyn screeched back! "Yes, that's it baby, you are filling me up! Don't stop, give Auntie Evelyn all of your tasty, babymaking seed!"

Totally spent, Billy's knees began so he carefully eased himself and Evelyn down to the shower floor. Looking deep into her eyes and barely able to speak, he told her. "Thank you Aunt Evelyn, that was absolutely amazing. I don't even know how to describe what I'm feeling."

"I don't know what to say either Billy, you were incredible. It's been a long time since I've felt this good. You are an absolutely amazing lover, but listen, we mustn't ever let your mother know about this. She would kill both of us. Do you understand?"

Billy nodded and asked, "Aunt Evelyn, can I slip over to your house tonight after mom and Shelley go to bed?"

Giggling Evelyn told him, "That's just like a man, never satisfied. I know I should tell you this can never happen again, but I can't. I'm not able to put my finger on the reason right now but somehow it just feels right. Listen honey, I think I'm going to need a good night's sleep after the shagging you just gave me."

Billy looked like he had just lost his last friend when Evelyn told him he wasn't going to be able to slip over later. He understood but it didn't make him feel any better. He wanted to fuck her over and over again.

Seeing the look of sadness on his face, Evelyn thought for a second and said. "Wait a minute, your mom has to run the silent auction at the school and Shelley has gymnastics practice tomorrow. We will have plenty of time to get together while they're gone."

"Damn, I forgot Sunday was Shelley's birthday. I have to give her something special. Turning 18 is a big deal. Will you help me Aunt Evelyn? I don't have any idea of anything I could get her." Billy responded.

Expressing to him she understood how hard it was for a big brother to buy a birthday present for his kid sister, she told him. "We'll go shopping first thing in the morning, but for now, we need to get cleaned up before your mom and Shelley get home."

The two lovers were almost through showering when they heard the kitchen door open and slam shut. Afterwards, Billy heard his mom calling for him, "Billy, we're home! Can you come help your sister bring in the groceries?"

"Oh shit, tell her you'll be right down while I get dressed. Now hurry, before she comes up here looking for you. I've already told you she will kill us if she finds us together like this. Besides, it would break her heart." Evelyn whispered to Billy.

Billy yelled downstairs to his mother that he would be right down. After running to his room, he put on a pair of shorts and bounded down the stairs. As he walked through the kitchen, he stopped and gave his mother a kiss on the cheek. He started telling her how much he missed her, when Shelley came through the door with the first load of groceries.

Billy grabbed the groceries from her and set them on the kitchen table. Being her regular bossy self, Shelly told Billy. "Come on lazy, there's a lot more where those came from."

Before following Shelley out the door, Billy looked over at his mom and said. "Well, it looks like she hasn't changed any while I've been away. She's still gotta be the boss."

His mom told him. "She's just excited about her birthday. Take it easy on her. Remember what it was like when you were her age. Now go and finish helping your sister."

Just as Billy and Shirley finished bringing in the last of the groceries, Evelyn walked into the kitchen. She had her head wrapped in a towel. Billy's mom turned and said. "Hi Evie, I didn't see you come in. When did you get here?"

Evelyn explained to her, "I'd just gotten out of the shower when I noticed Billy's car in the driveway. I knew you were gone so I dropped in to see if he needed anything."

Not suspecting anything, Billy's mom asked her if she would like to stay for supper. Evelyn declined saying she was tired and was going to bed early. Seductively she looked at Billy and said. "Call me in the morning and we will go find that thing you're looking for."

Sally Reynolds asked her son, "What is it you're looking for? Maybe I can help."

Billy didn't want Shelly knowing what he was doing so he went over to his mom and whispered in her ear. "It's a present for Shelly. Aunt Evelyn told me you had some things to do tomorrow so she volunteered to help."

His mom responded quietly. "That's right, I forgot about the auction at the school. I might get you and Evelyn to pick up her birthday cake for me."

Noticing all the whispering, Shelley began asking. "What are all of you talking about? It's about me, isn't it? I'm right here the room, or don't you see me?"

"We see you, we just don't want you to hear what we're saying. It's a secret and you'll have to wait until Sunday to find out what we're talking about. Don't be so damned nosey." Billy laughingly told his sister.

"It's just not fair!" Shelly exclaimed as she stormed out of the kitchen.

Billy went to the fridge, grabbed himself a beer and sat down at the table. He tried to listen to his mom and Evelyn while they were talking about the plans for Shelley's birthday party. Still, all he could think about was the tryst he shared with Evelyn earlier in the shower.

Reviewing the events in his mind, his cock was becoming rock hard underneath the table. His body began emitting his powerful pheromones immediately. It didn't take long for his scent to begin permeating the room.

Immediately remembering the alluring smell from earlier in the evening, Evelyn's body began to react instantaneously as her pussy began to tingle and tiny beads of sweat started forming above her upper lip. Evelyn knew she had to leave right away or face the consequences. Her panties were becoming soaking wet again.

Trying to make up a believable excuse, Evelyn told Sally. "Oh shit; I've gotta go, I think I left the water running in the tub. I hope it doesn't flood the house. Billy, call me in the morning and we will go get Shelly a special birthday present."

Before Sally could respond to her friend, Evelyn bolted out the door. That's when Billy's intoxicating smell flooded Sally's nose. Her nipples started to protrude out the front of her dress and her clit felt like it was on fire. She had suddenly become horny as hell and she needed a release.

Telling Billy to keep an eye on the stove, she flew up the stairs to her bedroom.

Upon reaching her bedroom, she ran inside and immediately locked the door. After practically ripping her clothes off, she opened the bottom drawer on her night stand and pulled out her vibrator. Turning it on and shoving it deep inside of her clean shaven pussy, she worked it in and out at a blinding rate of speed. She knew she had to cum fast or Billy would come looking for her.

Closing her eyes, she tried to fantasize the vibrator was a huge cock slamming into her pussy. It was working; she kept rhythmically shoving the vibrator in and out of her slick cunt. Her fantasy lover was about to put her over the edge when suddenly she saw her lover's face. It was Billy, her lovely son. It was his cock slamming into her.

Whether it was the taboo subject or the fact it had been almost three years since she felt a real cock inside of her, seeing Billy's face as her fantasy lover put her over the edge. When she started cumming her pussy began squirting her juices everywhere. This had never happened to her in all of her 46 years of being alive. She was moaning and screaming and didn't give a damn who heard her! "Oh my godd, that's it, make mama cum! Mama loves Billy's big hard cock!"

It had been almost 20 minutes since his mother left the kitchen. Getting a little worried, Billy went to see if she was okay. He was about to knock on her bedroom door when he heard her screaming his name.

Shocked upon hearing his name Billy thought. 'What did she say? Did she call my name? Does she want me to fuck her?'

That's when he heard her scream again! "That's it Billy, thank you, thank you! You fucked mommy good!"

Suddenly things fell dead silent and Billy could only stand there open mouthed. What was going to happen next Billy wondered? He started to go back downstairs but changed his mind when he heard soft moans coming through the door.

Laying on her bed softly moaning and thoroughly satiated, Sally hoped no one heard her when she was in the throes of orgasm. Beads of sweat were dripping down her tender breasts when a sudden knock on her bedroom door brought her out of her reverie.

"Mom, are you okay? I heard you calling my name." Billy called to her through the door.

Sally tried to compose herself as best she could under the circumstances and called back to Billy. "Yes son I'm fine. I stubbed my toe on the dresser when I came out of the bathroom. I'll be right down to finish dinner."

Her mind was reeling as she wondered. 'What came over me? Shit, why was I fantasizing about my son's cock? What am I going to do? He heard me calling his name? Did he know what I was doing up here?"

Billy headed downstairs with a wry grin. He knew exactly what his mother was doing in her bedroom. The way she was panting and moaning, there was no denying what was actually happening behind her bedroom door.

He'd never thought of his mother in a sexual way before tonight. Hearing her call out his name while she orgasmed suddenly made him see her in a different light. She was a vibrant and beautiful woman. He made up his mind to try and seduce her while he was home.
