Chapter 2

Sam ran back into his room, packed a few things in a bag and bolted out the door.

“I’ll be back before dinner” He called to Charlotte, was sitting reading a book in the lounge. She had barely looked up and the front door was closed.

Sam was running down the road at a jogging pace, wanting to get there in a hurry but knew he couldn’t sprint there. Soon enough he reached the forest and made his way back to the cave. Looking around inside he couldn’t see the alien.

“Hello? Are you there? What did you do to me? Why has my body change?”

“Hello Sam” the alien said very calmly as it came into sight.

“There is no need to panic. I told you that you would have all your desires. While I was penetrating you, I was also
accessing you brain, searching for your deepest desires.”

“My deepest desires?” Sam repeated sceptically.

“Yes, I have altered your DNA a little as well as opening up your mind a little.”

“My DNA? My Mind? How? Why?”

“No reason. Call it a reward for finding me.”

It was at this point the Sam realised that the aliens lips weren’t moving, but he could still heard it perfectly. He couldn’t believe it.

“My species has certain abilities from being able to read minds and changing DNA to mind control and suggestive thinking. I have given you the ability of suggestive thought onto people as I felt this would suit you the best., however there is a limit to what you can do. Such as you can create sexual craving in the mind of anyone. To make it overcome their thought process so much that they can think of nothing else until they have satisfied their craving.”

Sam couldn’t believe his ears, well his mind as it wasn’t actually talking.

“So I can make anyone I want to have sexual cravings for me?” He asked

“Not quite, you can just make them so sexually frustrated that they can’t think of anything else and give in to the nearest relief. If that is you or someone else or themselves all depends on the person and their will power.” It answered.

“Which brings me to the physical side. I have made your body more muscular an athletic, made your sex organ bigger and thicker, also to appeal to anyone you desire, Instant recover for regular use and a longer lasting ability. You will now release you seed when you want and lastly, your production of your reproduction seed has increased tenfold. You will produce a large amount almost straight away and will drive all who taste wild for more. To put it as simple as possible, you are now a sexual being among humans.”
Sam just stood there in disbelief.

“Now leave, one day you will return to me and I will have a job for you but until that day, do not return”

Sam left dumbfounded and not sure how to take it all. It was as if all he dreams had come true. As he walked home he kept running over and over what the alien had said, trying to comprehend it.

When he got home no one was home again so he went to his room, stripped off, pulled up a porno to watch and he was just too horny. He didn’t know if it was from the change in his body or because he wanted to test it or what but all he knew was he wanted to jerk off badly.

He started watching the video, the first one that popped up, and instantly got hard. He looked down to see this big, thick, hard cock pointing towards the screen. He couldn’t believe the size. Where his 7 inch member used to hang stood proud veiny 9 Inch and he guessed 2.5 Inches thick cock. Reaching down he wrapped his fingers around it and slowly pulled it back relieving a big purple head. Then back up, and down.
“Oh. Wow. Man that feels good.” He sighed. It felt so different. He just kept speeding up stroking his new cock. Getting up and admiring his new body in the mirror in his bathroom, stiff dick still in hand, pumping away. He stood there for a good ten minutes stroking his member, taking in the fantastic feeling it gave him.

While he had been doing this, he hadn’t realised that in fact the house wasn’t empty, Melissa had been in her room flicking though a magazine when she had heard some noises coming from her brothers room. She went to her door and opened it. What she saw made her jump and she shut the door immediately. Breathing quickly she couldn’t believe her little brother was just standing in the bathroom stroking his shaft. Then she found herself thinking that she never noticed before but he had a fantastic body.

Stopping herself, she thought that it was ridiculous the way she was thinking, but then though one more peek wouldn’t heard anyone and cracked the door. Sure enough Sam was still there pumping himself, moaning. Mel, hiding behind the door couldn’t take her eyes off him. She certainly wasn’t a stranger to the male body but he was on another level of hotness that she had never notice. Her eyes devouring his body, were tracking down, once her eyes made contact with his penis that was it. Her body temperature increased with her breathing.

As Melissa watched, she started squeezing her tits through her top. Her nipples felt very sensitive today compared to usual. She didn’t really give it another though. She was no stranger to men but she didn’t exactly get around either. She knew boys could wait till after high school. Plus her Dad would kill her if her knew she had had sex. She had watched some when she masturbated but had never seen a cock that made her mouth water like Sams.

Sam Turned around left the bathroom to focused on his new body to see his sister watching him. He strode back to his room without taking his hand off his cock. Back in front of the porno he increased the speed of his strokes building to blow his load.

Mel creped after her brother when he left to go back to his room, trying to be very careful not to make a sound. She leaned around his doorway and saw him sitting there watching his laptop. She could see a little bit of the porno but that didn’t interest her.

After about 5 more minutes he leant over and opened his bottom drawer and pulled something out. At first she couldn’t tell what it was. It was black, crumpled up material with white stains on it. She figured it was his come rag she had heard about but didn’t think boys actually kept one.

He unwrapped it a little bit and she saw lace and thought that was strange, then it hit her. They were panties, her panties. She couldn’t believe it and all most said something but caught herself before she did. Just watching quietly not wanting it to end.

Sam took the unravelled panties and aimed his penis at them and shot after shot of thick white goofy cum all over them. He just keep shooting. It just kept coming out, soon the pants and his hand was covered in his load. Some on his desk and some landed on the floor. Wow, he thought to himself, what an orgasm.

Melissa just watched in silence and shock and her little brother just unleashed a torrent of cum. If the amount released wasn’t enough to make you cum, the smell was heavenly. It smelled nothing like the cum of the other boys she had sucked off. She really wanted to taste it but knew she couldn’t. As Sam started calming down she decided to play it safe and retreat back to her bedroom tend to her aching pussy.
She raced back to her room, stripped off, removing her now soaked panties. She hand never been so turned on. Why? Was it because it was her brother? Because she knew it was wrong? She didn’t really care, she just let her fingers explore you’re her pussy. She loved how it felt, how smooth it was, how wet it was. She ran her finger up and down her pussy lips, occasionally hitting her clit. She became more and more aggressive as she gave into her lust. Pushing one finger into her cunt, then another, pushing in and out, over and over. Her other hand pinching her really sensitive nipples.

Picturing Sam stroking his mammoth cock to her naked body, wanting it in her, wanting it to stretch her and fill her. She didn’t know what had taken over her. She was never this sexual before. Never been this horny. Mel’s fingers worked there magic on her g spot and soon hand herself writhing in pleasure, bringing her to the biggest orgasm she had ever had. Lying there recovering and regaining her senses she dozed off.

Over the next week Sam took his cock out and masturbated as regularly as he could, not once did his dick feel sore or over used and every time he came there was just as much as the first time. Mel also spent the next week masturbating furiously. She could understand why she was always horny. She was regularly fantasizing or day dreaming about sex. Their parents noticed they were spending more and more time in their bedrooms but just kept a closer eye on them, they seemed fine.

Next Saturday rolled around and for once Melissa wasn’t going to beach with her friends, she was actually staying home. Being a hot sunny day they decided to go and laze by the pool. Melissa had on a new bikini she had recently bought. It was very skimpy and she knew it but wanted to give her brother something to look at. It was a string bikini that barely covered her nipples with a little material and the bottom half was thong that was very small in the front.

It’s wasn’t something she would normally wear but it seem to the job, the look from Sam said everything but she pretend not to notice.

Sam couldn’t believe his eyes. The bikini his sister had put on covered all of nothing, and he loved it. He took his sunnies off and jumped in the pool, cooling off, also allowing him to manoeuvre himself to get the best possible view of his sister. As he was floating around the pool he remembered what the alien had said. Power of suggestion or something. Time to see how well this works. He made his way over and got out of the pool next to Mel and lay down.

He closed his eyes and thought for a second. He wasn’t sure how it worked but he got the feeling that he just had to will them and it made it worse. Just being near someone had an effect on them, nothing major just turning them on. As he was lying next to Mel he started willing her pussy to get wet and for her to be quite turned on. He could see it was working as she began to fidget more and her nipples were pointing skywards. He could feel her getting hornier.

After a while she promptly stood up and stated that she was going swimming.

“You ok sis?” Sam asked.

“Yea fine, just hot that’s all” Mel replied without knowing why she was so horny.

Just as Mel dived in the phone rang.

“Ill get it, you swim” Sam said as he got up and walked into the house.

When he came back outside he had made sure to make the outline of his penis visible through his shorts. Mel met his on the side of the pool, crouched over he said

“Mum and dad are stuck up north and it could be for the night. Looks like it’s just you and me tonight.”

Mel smiled “Awesome”, not really sure if that is a good thing she thought to herself.

“Come on lets go inside and grab some food then come back out” Sam smiled.

Mel lifted herself out of the pool on her arms in front of Sam giving him a great view of her tits. Sam stood up to give her room so when she was half out of the water her face was right a groin height. It was getting to be too much; she could see the outline of his huge cock and if she didn’t relief herself things would get very interesting.

They Both went into the kitchen and started putting the together something to eat, as Mel was bend over looing in the pantry Sam went over to her, willed some more horniness at her and just watched. He could see what he thought was her juices running down her leg but wasn’t 100% sure so he keep going. He knelt down behind her and breathed through his nose, she smelled fantastic and he knew she wouldn’t say no to him so he reached up to the ties at the side of her bikini pulled them releasing the thong, before pulling it out from between her legs. She was perfectly waxed, smooth and hairless, just the way he liked it. Mel let out a slight moan when the ting had been taken off and was fighting to hold back more as she felt his breath on her dripping wet cunt. She was just too horny to do anything. She wanted him and nothing else mattered.

Sam took her ass cheeks in his hand, spreading them, sticking out his tongue he ran it from just below her clit, up between her pussy lips. Taking in all the juice and flavour he could. Once he reached her ass he flicked over it, then ran back down her pussy. Teasing her over and over.

“Oh Sam, yes, lick me. Lick my pussy. You make me so wet I want to cum. Tongue fuck me, pllleeeeaaassssseeee.” Mel Moaned

Sam just buried his tongue deeper in you tight snatch. Mel was a moaning mess by this point as Sams tongue kept up its attack. Mel, count take it any longer and when Sam sucked on her clit her pussy exploded with a mind shattering orgasm causing Mel to fall to the floor.

Look down at her, pleased with himself Sam smiled and dropped his pants, his cock hard and waiting for her. Mel couldn’t get her head straight, all she knew was pure lust and there, right in front of her face was her brothers big fat hard cock. As if she was a addicted, she reached up and started stroking his meat. She couldn’t get her fingers completely around it it was so big.

Sam reached down and undid her bikini top and let it fall to the ground releasing her beautiful tits. He was enjoying the sight but couldn’t get too lost in the sight as Mel knelt up and starting licking up the length of his shaft. Savouring it. Loving it. It was perfect in her eyes. With her mouth-watering she had to taste it, had to have it in her mouth.

She put the tip in her mouth, sucking on it, licking around the head. Moving down the shaft, slowly as the size made it difficult but nothing was going to stop her from sucking this gorgeous penis. Back and forth her head bobbed taking more and more into her mouth. Sam moaning and encouraging her to take more. She stopped with half of it in, she couldn’t take anymore, so she backed off and kept sucking. Her saliva was going everywhere, down his shaft, from her chin, on her tits. It was a very sloppy bj and Sam loved it.

Melissa keep sucking, she could taste his pre-cum and there was nothing sweeter she had ever tasted. She wanted more. Her hand was pumping his shaft with the other one rubbed her pussy. The hand on his shaft was increasing in pace as well as her sucking, wanting cum and wanting it now. Sam moaned more and more, thrusting to meet her mouth. He wanted to cum and could feel it rising from his balls.

“Im about to cum sis” Sam moaned to his sister. This only made her speed up again knowing that his fantastic load was on its way to her eager mouth. All of a sudden Sam went stiff as his orgasm hit.

“Aaaaaaaaaahhhhhhhhh yes!” Sam cried

Shot after shot of cum came flying out into Mels hungry mouth. She knew there would be a lot but it still took her by surprise and she mouth was quickly filled and she couldn’t swallow quick enough to keep up, it didn’t help that she was being rocked by another orgasm and couldn’t keep a hold of his cock in her mouth.
Sam took over and grabbed his cock and keep pumping it at her, spraying her with cum. Covering her face, getting some in through her hair and all over her tits. When he stopped shooting his white goo everywhere he looked down at her and gave a big smile.

“You have never looked more sexy my gorgeous sister”

Looking up and smiled back at him.

“I’ve never been happier” She said as she started scrapping his load from her face into her mouth. The first time she had tried cum she couldn’t say she liked it but then also couldn’t say she didn’t but his, his tasted incredible, she couldn’t eat enough of it. She cleaned up herself as best as she could with her fingers. The rest that she couldn’t get or didn’t get she just left there. She loved the smell and the feel and could bring herself to wash it off. Why would she if she loved everything about it.

She got off the floor and they went back to getting out food to eat even though she wasn’t that hungry, well not for lunch anyway. Neither of them bothered to get dressed, they knew it was pointless. Sam smiled and said if she was good girl they would have more fun later. If mum and dad don’t come home on them. She reluctantly but she knew there was going to be more fun to come. Nothing would be the same….
