Chapter 2. Martian Sisters

In a two story house, located in Happy Harbor, three people were in the master bedroom.

One was the 16 year old ninja named Naruto Uzumaki.

The second was a woman whose skin looked completely pale like chalk, amber colored eyes, and red hair. This is Miss Martian aka M'gaan M'orzz or Megan Morse to her friends.

The third was also a woman who was green skinned, her eyes were red, and her hair was a dark red. This is Megan's sister Em'ree M'orzz.

Naruto wasn't wearing anything as he was naked. The same could be said for the two Martian sisters.

Megan morphed some clothing in the form of sexy lingerie. A red bra with matching panties and a garter belt.

Em'ree was wearing matching set but was all blue.

'I can't believe you talked me into this.' Em'ree said with a blush on her face.

Megan turned to her sister and said with a smirk 'Oh come on sis. You said that you were curious about human mating rituals.'

'I know that. But I didn't expect for you to bring me to your Earth home in order to sate my curiosity.' Em'ree said while giving her sister a dirty look. 'And with a human who is still a juvenile.' she said looking at the blonde.

'Hey, you lost the bet. So you have to go through with it. And besides from what I heard, Naruto is quite the lover in bed.' Megan said while sending a seductive smirk towards the blonde who returned it.

'And how would you know that? More importantly how can you be so sure those were not words of hot air?' Em'ree asked still not buying it.

Megan just sent her sister memories of Naruto being with other women. Heroines, villainesses, female civilians, police women, female soldiers, females aliens, and female civilians. Some single and others that were girlfriends or wives in a bad relationship. And only a bad relationship.

Em'ree blushed upon seeing so many faces of all these women. Many of them had looks of satisfaction on their faces. And many of the female villains looked to have walked away from their life of crime. If only for this blonde ninja to give another good time in the sheets.

'And you invited me to end up like all these women?!' Em'ree spoke to her sister incredulously.

'Hey you've been in need of some time away from your work. Plus you have also been curious if Martians and humans are compatible to reproduce with each other.' Megan explained before continuing'As far as I am concerned this is a good idea to, as the humans say metaphorically, kill two birds with one stone.'

Em'ree was glad to have been told of these kinds of metaphors the humans made. As she would've misinterpreted most of them.

Breathing a sigh, Em'ree said 'Alright. Let's get this over with.'

Megan smiled then turned to Naruto and said "Well Naruto good news is this threesome is happening."

Naruto looked at Em'ree and asked "Are you sure? I wouldn't be upset if you backed out. It's your choice."

"I'm sure. But I do appreciate your willingness to give me a chance to leave." Em'ree said glad that the blonde wasn't planning to force her into this.

(Lemon)

Megan got on her knees while urging her sister to do the same. Then she reached out and took Naruto's towel off.

Em'ree was shocked by the size of his dick. Granted she never saw any reproductive organs of any race before, hers included, but even she doubted any human should have something that big.

'Is he even human?! Or is this what all meta humans have?!' Em'ree mentally shouted in her mind.

Having telepathy herself, Megan smirked upon hearing what her sister said. She responded in kind 'If you think it looks great up front just imagine what it'll feel like inside of you.'

Leaning forward she gave the engorged male appendage a deep sniff before she took it into her mouth. Causing Naruto to groan in pleasure. And with her shapeshifting abilities there was nothing for her to worry about since she could remove her uvula and stretch out her throat.

Em'ree was shocked by what she saw her sister doing. Knowing what she was thinking Megan said con 'This is called a blowjob. The women of this race always to do this to the males. Only if they want to of course.'

Naruto then said with his teeth clenched "Damn Megan. Those shapeshifting powers are definitely great more than kicking bad guy asses."

That made Megan smile before she removed her mouth from his log and said "Oh you haven't seen anything yet stud."

Megan then made her breasts into a DD-cup and wrapped them around the pole before moving stroking it up and down. She even went back to blowing it.

For reasons unknown to her Em'ree was feeling her own nether's getting wet. She rubbed her legs together.

Seeing this Naruto said while groaning "You can join in instead being a spectator you know."

Megan, who heard what he said, responded telepathically 'He's right. Why not come over and try it yourself?'

This made Em'ree blush in embarrassment. She then said "Are you mad sister?! You expect me to-?!"

She was interrupted when Megan said 'A scientist must learn to take part in experiments in order to gain experience. And besides you're clearly aroused. I can sense it just as much as Naruto can.' Taking said man out of her mouth she finished "Now enough dilly dallying and start sucking."

With a twitching eyebrow she sighed in annoyance before joining her sister. At first she looked disgusted with it being lathered in her Megan's saliva. Then she went in and took it into her mouth.

Like her sister she suppressed her gag reflex and stretched her throat. Then she started bobbing her head up and down.

At first she asked herself how did she get into this situation but a few minutes later she began to enjoy it.

Megan then said to her "Wrap your tongue around it. He'll like that."

After giving her sister a side glare, she did as instructed. She did feel a little smug when she heard him groan.

"Damn, she's good and this is her first time." Naruto growled while placing his hand on her head and easing her down his cock a bit further.

"She's a fast leaner. Which isn't a surprise since she's the head scientist back home." Megan said praising her sister.

Em'ree was happy to hear her sister praise her. She vowed to be a better sister than she was back then. And that's a promise she refuses to break.

She then felt Megan tap her shoulder. Knowing what she wanted, Em'ree moved over to let her sister have her turn again.

The two Martian sisters continued to switch every fifteen minutes until Naruto felt his climax was upon him.

"Ah! Girls, I'm gonna cum!" Naruto warned through gritted teeth.

Hearing this, Megan, who was letting her sister get a turn again, said to Em'ree "Now sis this is the part where you let him cum inside your mouth. It may not taste great but trust me you'll like what happens after."

Before Em'ree could ask her what she meant by that, she was surprised by what happened next.

Naruto pressed down on her head and held her there as he came in her mouth with a groan. She was surprised by the huge volume of human sperm being injected into her mouth.

But thankfully her Martian abilities helped her in this situation. She was able to widen her throat so that all of it could go down easily.

A few minutes later, Naruto gave a sigh of satisfaction as he finally stopped shooting his load into her maw.

Em'ree was surprised by how much he came. She theorized that she swallowed only half of the sperm he shot into her mouth. Whatever is left is currently still in her mouth.

She then heard her sister say "Don't swallow the rest Em'ree. Just take his cock out of your mouth without spilling any. I want to show you something that he would definitely like."

Upon hearing the tone in Megan's voice, Em'ree knew her sister was up to something. But she followed her instruction anyway.

After removing herself from his cock, Em'ree was not prepared for what happened next. Megan, her own sister, took her by the head and collided her lips to her own.

Both Naruto and Em'ree were shocked by what she did. Naruto believed that him and her having sex in the past must've awakened a part of Megan that wasn't there before.

Em'ree was still having a hard time processing what was happening. Her own sister was kissing her like they were lovers. She even felt Megan's tongue slosh around through all the cum in her mouth while scooping some out and taking it into her own mouth.

At first her first instinct was to stop this. To remind Megan that they were sisters but she felt so aroused for some reason. She soon got into it and started to kiss her sister back. While also meshing their tits together.

Apparently this got the reaction out Naruto that Megan was talking about. His cock went from half mast and back to full mast. Two alien sisters making out with each other while also sharing his cum.

As soon as the two sisters were done and Megan scooped the last of the blonde stud cock cream out of Em'ree's mouth before swallowing it the two were grabbed and thrown onto the bed.

Megan landed on her back while Em'ree landed on top of her. Looking up she saw the face Naruto was sporting.

Knowing what was about to happen she gave her sister a reassuring and lust filled smile. Then she said "Sister it's time for you to know what it's like to breed with a human."

Em'ree felt her love passage moisten in anticipation. She was going to let a human, a descendant of Neanderthals, put his seed into her womb.

She allowed herself to remain fertile so that she could know what a human/martian hybrid would be like.

Feeling his hand on her hips, Em'ree breathed nervously before she let out a loud yell.

"AAAAH!"

Naruto sent his cock directly into her alien cunt. Punching past her cervix and into her womb. Which she willingly chose to remain fertile.

After giving her time to adjust, the blonde ninja began wrecking her pussy.

"Aaah! Aaah! Aaah! Oooh! Ugh!" These were the sounds Em'ree made. Telling everyone that she was feeling great from having her snatch stretched.

She took the initiative to make herself tight for the human. And she was glad to have done so.

Em'ree fell face first into her younger sister's cleavage. Looking up she moaned while saying "M-M-Megan h-he's plundering my depths! Oh for the love of all science he's rearranging my insides!"

Megan pulled her sister in for a kiss. Muffling her moans of pleasure. The two sisters entered another make out session while the eldest of the two was getting back shots. Apparently the sight made their human lover go even harder.

She then felt him hit an area in her pussy. Making her shoot up and let out a louder yell. Looking back she asked "What was that?!"

While smirking cockily Naruto answered "That was me hitting your G-spot. And now that I found it I'm gonna hit again."

True to his word, Naruto repeatedly struck her G-spot over and over again. Em'ree honestly didn't know she had a G-spot.

Looking to her younger sister, she asked while still in the throes of pleasure "Is it always like this on Earth?!"

Smiling sexily Megan responded "Yes sister. Yes it is. At least with him of course."

Em'ree soon felt the human stud grab her by the breasts and started to fondle them. The green skinned Martian turned her head over her shoulder to gaze into his eyes. What she didn't expect was for Naruto to claim her lips with his own.

But she soon melted into the kiss. It was then she realized that not did this human take her virginity he also took her first kiss. And very soon he will soon be breeding her.

She was originally curious about whether their two species were compatible to breed. But if they were then she promised to raise their child. And deep down she believed the human would do the same.

Her eyes widened upon feeling something wet and warm on her nipple. Looking down from the side of her eye she saw that Megan was sucking her left breast.

Megan mentally replied 'Did you expect me to stay out of this sis~?'

Em'ree then said in an accusing tone 'I have a strange feeling you planned this.'

Megan just smirked while still having her sister's nipple in her mouth. Then she suck a bit harder drawing out a on the little nub while also licking it.

Em'ree felt herself getting extra wet upon realizing that she was getting double teamed by Megan and Naruto.

It didn't help when she felt herself about to cum. She then mentally said to the human stud 'I'm gonna cum! I know you're gonna cum too! Do it! Plant your human seed inside my Martian womb!'

Not needing to be told twice he started thrusting harder into Em'ree until he hilted his cock into her body. Then like a firehose he spewed a deluge of his chunky juices into her womb.

Em'ree felt her eyes roll into the back of her head. She then squirted her release all over his cock as the thought of his sperm was swimming towards her eggs.

After Naruto was done, Em'ree rolled to the side and was panting hard to get some air into her lungs. She knew that without a doubt her eggs were fertilized by Megan's human friend.

But just as she was about to cross over into dreamland, her eyes widened upon feeling a pair of lips on her nether lips.

Looking down she saw that her sister face was buried between her legs and her tongue was slithering in her already sensitive cunt.

"Me-Megan! I'm really sen-sen-sensitive! You ha-ha-have to-o-oooo stop!" Em'ree tried to say while trying to remove her sister from her maiden hood.

Megan just swatted her hand away and continued feasting on her elder sister's cum filled twat. All the while shaking her pale booty at Naruto.

Who was back to full once more. As he got behind Megan and aimed his dick at her cunt, he said "Time to breed another Martian."

With a strong grip on her hips, he crammed his dick into her folds. Making the white Martian moan in her sister's cunt.

Which made Em'ree moan louder. She gave up on getting Megan to stop and just settled for fondling her breasts.

Megan felt her mind melt from the pleasure coursing through her body. Her pussy singing out in ecstasy from being roughly and ruthlessly penetrated over and over again.

And to make it even more of a turn on she was in between the green thighs of her elder sister and munching on her green cream filled twat. And a part of her doesn't even care if it's wrong.

The first time she slept with Naruto was the day she was introduced to a whole new world of pleasure. She didn't care if he slept with other women. Any man who can satisfy that many women shouldn't be held down by one woman.

She didn't even mind if he got her pregnant. She'd raise the child to be an even greater hero than both her and his/her daddy any day.

A few more minutes later she heard him groaning. Signaling that he was almost there. She wasn't far behind as well.

After giving her few strong back shots, Naruto punctured his way into her womb and discharged his human load into her. Before the white skinned alien girl soaked his cock.

Megan moaned into Em'rees pussy. In turn causing her to spray her juices into her sister's mouth.

(Lemon End)

After all three came down from their high Megan and Em'ree lied down with their shared human lover in between. Naruto wrapped his arms around the Martian beauties and all three went to sleep.

On Mars

'You're both pregnant?!' was the question their parents, M'aatt M'orzz and J'ann M'orzz, asked in shock.

Both Megan and Em'ree stood before their parents. The latter looking a bit embarrassed as she held her face.

'Please tell me the human gift you both with children didn't trick you two into breeding with him.' their father begged.

'Father I promise we weren't trick. Em'ree was just curious about whether humans and Martians were capable of reproducing children together. I simply joined in.' Megan confessed.

Both parents looked to their elder daughter with the mother asking 'And you chose this method to perform this experiment of yours because-?'

'I couldn't just ask a random human to come to Mars and experiment on them mother. And now that we know our two species are more than capable we decided to keep the children. And the father of our unborn children said he's willing to step up and help.' Em'ree said with her and Megan placing their hands on their wombs.

Both parents were silent at first until M'aatt sighed before saying 'You two are adults so I have no say over what you do with your lives. But you will notify us when the children are born.'

Both sisters grew happy faces and hugged their parents. J'ann then asked 'And where is the father?'

Megan was the one who answered 'Oh he's on the Watch Tower with Uncle J'onn. Who is currently "venting"."

In Earth's orbit on the Watch Tower

"I...regret...nothing!" Naruto managed to say while being choked out and shaken by an angry J'onn J'onzz. The rest of the League were trying to pry his hands off the young ninja's neck.

Granted J'onn wasn't aiming to kill him. Just express his feelings physically.
