Rachael Cummings had wanted to go to space ever since she was old enough to realize what the solar system was. She studied the history of space exploration every chance she got. She learned that, back in the year 2030, man made its first interplanetary trek. After colonizing the moon, the first Mars mission was easier to accomplish. Fifteen years later, man set foot on Jupiter's moon, Europa.

A primitive form of life was discovered there that accelerated man's quest to learn more. New technologies were developed that allowed man to reach Pluto and beyond. By the year 2050, man developed the first FTL (faster-than-light) drive and, less than four years later, reached Andromeda.

By the year 2075, man had vastly improved the FTL drive and interstellar communications. Mankind was exploring even further into the solar system. New life was discovered everywhere. Planets that were Earth-like and contained life on our level were discovered. New technologies were learned and quickly integrated into our own.

By the year 2200, mankind had colonized several planets and made friends on many more. Although our space vessels could defend themselves, we rarely used those weapons. Advancing our science and improving our way of life took priority. Man no longer needed to fight for resources. The universe held plenty.

Rachael wanted to be a part of this exploration. She spent all her spare time studying biology, physics, chemistry, and mathematics. By the time she started high school, she had already mastered calculus and advanced physics. When she wasn't studying, she made sure he was physically strong enough for what she desired.

She ignored all the boys, except for a few. This was especially true when they made stupid remarks about her last name. Most of the boys suspected she was into girls, but that wasn't true either. She had a good number of female friends, but it was just friendship.

Since the day Rachael turned sixteen, she lived vicariously through her best friend, Janine. Janine was over a year older than Rachael, sexually active since her sixteenth birthday, and more into the shenanigans of their generation. She kept Rachael informed about who was kissing whom and who was doing more than kissing.

Rachael couldn't fight the changes happening to her, so she kept to her books. She didn't have time for frilly girls' clothes and dressed rather plainly. Only her family and Janine ever saw what she really looked like. Being an only child made it easier for her to hide what she had become.

That was all about to change. At her seventeenth birthday party, her mother made her dress up. By dressing up, she was made to wear a dress, plus it was a pool party. She put on a dark blue sundress her mother had bought her over the top of her normal two-piece bikini.

When she appeared, she could hear everyone take a deep breath. Janine walked up to her and said, "Fuck, girlfriend, your secret is out now. You might as well enjoy it."

Rachael took a deep breath and welcomed everyone to her party. She had to admit the boys' attention was a bit thrilling. She felt her body reacting to their attempts to hit on her. That was especially true of Josh. He had the same dreams as Rachael, but he wanted to be a pilot and to one day sail among the stars.

Rachael noted from the look on Josh's face that he liked what he was staring at. She liked what she was looking at and that he was looking at her the way he was. Her mind wasn't on science at all, but on the well-developed specimen of a male she was looking at.

Rachael at the time was five feet, eight inches, with soft blond hair and blue eyes. Her hair was braided, as it normally is, and the braid hung over her shoulder and across her breast. She was rather athletic with defined muscles, but not too defined.

While her belly was flat, her chest was not flat. She wore a C-cup bra and would likely be better suited for a D cup, that is, when she actually wore one.

Her dress barely covered her shapely ass. If she bent over, her bikini-covered ass would be exposed.

She felt her pussy moisten and her nipples stiffen as Josh looked at her. She wasn't used to feeling either of those things, but she was enjoying the feeling. It didn't help her any when Josh walked up to her and kissed her cheek.

Smiling, Josh said, "Damn, girl, look what you have been hiding."

Rachael smiled back and said, "Thanks, I think."

Josh replied, "Yes, Rachael, that was my attempt at a compliment."

Rachael felt a twinge between her legs as she grinned and said, "Okay, then, you don't look so bad either."

Rachael couldn't deny Josh really was looking fine. Nor could she deny how her body was reacting. She was well aware that her body had changed from being what everyone thought of as a simple nerd into a being capable of developing another human being. She also knew and was aware that it involved men having a sexual coupling with her. Right now, her breeding instincts were quickly gaining control over her logical self.

After about an hour of flirting back and forth, Rachael had feelings she wasn't sure how to handle. Her heart raced, and her breathing increased every time Josh touched her. She was liking the flirting and didn't want it to stop. As time passed, the flirting got more and more suggestive.

Several times Josh asked her to dance, and she relished feeling his strong arms around her. She'd softly moan anytime she felt Josh's hand touching her ass. From the feel of Josh gently squeezing her cheeks, she was sure he heard those groans.

The world around her slowly disappeared as they danced arm in arm. She could feel the heat coming from Josh's pelvis. She was sure he could feel her.

She was in Josh's arms and about to kiss him when her mother announced the pool was open. Rachael stopped dancing with Josh, and without much thought, she stripped off the dress. She dove into the pool because she really needed to cool off her overly excited body.

Josh sucked a deep breath and mumbled, "Well, fuck me." Rachael's swim gear left little to the imagination. Josh felt himself start to react to the sight of a scantily clad Rachael diving into the pool. He quickly stripped off his shirt and shorts and dove into the pool over the top of Rachael.

When Rachael looked up and saw what Josh wanted to hide, she moaned a bit louder. Rachael felt her clit react to the shape and size of what she saw. Rachael was familiar with human anatomy and knew all about sex. Even so, Josh was well endowed, and Rachael liked what she saw. She thought, "Your body was telling you to loosen up."

Janine said it out loud, "Girl, if you don't let that fuck you, I will let him fuck me."

Rachael looked at her friend and replied, "Back off, girl." Rachael was ready to experiment with her sexual awakening with Josh and didn't want Janine to have him first

Rachael's clit was thumping at the same rate as her heart was when Josh swam up behind her and pressed her against the pool wall.

Rachael felt his hard cock press into her ass as he whispered in her ear, "You know you caused what you are feeling."

Rachael thought, "Okay, this is happening," but she giggled and replied, "Did I?"

Josh said, "Yes, seeing how gorgeous you are is making me want you even more."

She looked up and saw Janine leading a guy into a nearby clump of trees. She watched her friend kneel down and pull down the guy's swim shorts. Rachael said, "What is Janine doing?"

Josh saw it too and said, "Janine is about to suck his dick."

Rachael reacted by pushing back against Josh and moaning softly and saying, "Is she?"

Josh replied, "Look again."

Rachael saw Janine open her mouth. Rachael could see the guy holding her head and guiding his cock into her mouth. Rachael felt herself getting more and more turned on. She felt Josh's cock twitch, and she moaned softly.

Josh licked her ear and whispered, "Enjoying what you're seeing, gorgeous?"

Rachael couldn't deny she was and just nodded. After a couple of minutes, she heard a faint grunt from the guy and watched Janine put his cock back into his shorts.

Josh said, "Keep watching."

This time Janine turned to her right as one of their mutual friends approached her. Janine reached up and pulled down the person's bathing suit. His cock popped free. Rachael moaned again as she watched her best friend start to lick his cock.

Rachael found herself actually mimicking Janine's movements and felt Josh put one of his hands on her bare belly.

Rachael closed her eyes as Josh's hand started to move down her belly. She pressed back against Josh when his hand hit the wall between them. Her movement gave Josh enough room to slide his hand down further.

As Rachael watched Janine sucking cock, she spread her legs, and she reached behind her for Josh's cock.

Josh's hand was really close to her pussy as he whispered in her ear, "Don't start what you aren't willing to finish."

Rachael considered that comment for a moment. She pushed Josh's hand between her legs and whispered, "I am willing."

Since her feet were on the bottom of the pool, she reached back with her other hand and used both hands to free Josh's cock. He pressed his bare cock against Rachael's almost bare ass. Rachael moaned as she felt Josh move his cock up and down the crack of her ass.

Rachael felt both of Josh's hands pull the ties on each side of her bikini bottoms, pulling the cloth free of her body, and press back against her now bare ass. Rachael moaned again as she felt one of Josh's hands touch her bare pussy lips and saw her bikini bottoms placed on the pool deck along with Josh's swim trunks.

Janine was now sucking two guys at the same time, and Josh whispered, "You're pretending Janine is you. When she sucks my cock, I pretend she's you."

Rachael turned her head towards Josh and replied, "She sucks you?"

Josh laughed a bit and replied, "Until you start, a guy has to do."

Rachael moaned again, turned, and faced Josh. Now his bare cock was firmly pressed into her belly, and she replied, "You want me to suck your cock?"

Josh leaned in and kissed her hard. Racharl ground her hips against his and moaned much louder. Josh broke the kiss and said, "Well, not in the pool unless you can hold your breath, but yeah." One of his fingers inserted into her pussy, and he continued, "And I want to eat this too."

Rachael had her hand firmly wrapped around Josh's cock. She stared at Josh as she watched his face. It was obvious he was enjoying her stroking his cock. She was definitely enjoying Josh playing with her pussy.

She gave Josh a quick kiss and asked, "You want to eat my pussy? Did you eat Janine's?"

Josh replied, "Yes, I want to taste your pussy. Yes, I have tasted Janine's pussy. Does that upset you?"

She kissed Josh's chest and said, "No, it actually doesn't bother me. If I get out of the pool half-naked, everybody will know what we are about to do."

Josh laughed and said, "Babe, I am pretty sure everyone already knows, considering our clothes are on the deck."

Rachael kept stroking Josh's cock and wondered if anyone was really watching. She replied, "I guess they do?"

Josh turned Rachael back around and said, "Look at Janine now.

Rachael turned her gaze to Janine, who was bent over, sucking one guy while being fucked by another.

Rachael felt Josh slip his cock between her legs. She mumbled, "Oh fuck, that feels good."

Josh nibbled on Rachael's ear and said, "It will feel better soon, love."

Rachael said, "You really love me, or am I just the flavor of the day for your pleasure? What if my parents see us?"

Josh whispered, "Honey, your mom is probably in her bed getting hammered by John's and Billy's father. Before you ask, look closely at the second guy doing Janine."

Rachael looked and squeaked, "Oh fuck." She recognized her father, and he had Janine bent over, holding on to a tree. He was pounding Janine from behind.

Rachael chuckled and mumbled, "Well, she is over eighteen."

Rachael reached down between her legs and pressed Josh's cock against her pussy lips. She moaned as Josh slid his cock back and forth across Rachael's more than ready pussy.

Josh nibbled on Rachael's ear and said, "So dear, are we going to do this? Do you want to do it here or some place else?"

Rachael thought about it for a few seconds and pushed her ass back, and using her hand, she lined Josh's cock head up to her pussy lips. He slowly slid forward as his cock started to spread open Rachael's pussy.

Rachael groaned, not so quietly, as she closed her eyes and let Josh fill her pussy. She had lost her hymen long ago from all the exercising and self-love she did, so she wasn't in pain as his cock made its way inside her.

Josh grabbed her by the neck and pulled her upright as his hips touched her ass. He proclaimed, "Fuck, you are tight."

Rachael gasped, "Fuck, you are huge."

Rachael looked around the best she could and saw that her friends were watching and moaned, "They're watching."

Josh, sliding in and out of her tight love hole, replied, "Yes, they are."

Rachael giggled and said, "That actually turns me on even more. Ohh gawd, fuck, you feel good inside me. Can you just stop and let me enjoy this feeling?"

The water stopped churning between them as Josh did as Rachael wanted. Rachael knew there really was no stopping the conclusion of what Josh was doing to her now, but she just wanted to relish the feeling of being filled by him first.

Rachael had a momentary thought. She knew Janine wasn't shy about sex. She never liked the term "slut," but Janine was as promiscuous as one could be, and she thought, "Would she be like Janine and let anyone fuck her, or would she exclusively belong to Josh?"

Josh answered that question: "I saw, I conquered, and I am about to cum in my girl."

Rachael giggled. Even without Josh moving, her first orgasm from being fucked hit her.

Josh, gasping as he felt Rachael's pussy tighten around his cock and her body shake, asked, "What was so funny?"

She gasped, "Cummings is cumming."

She felt Josh's cock twitch inside her as he started laughing too.

Josh held Rachael still as his cock remained hard and inside her. If he moved at all, he'd cum. Then he proclaimed, "Oh shit, are you..."

Rachael hushed him and said, "I have been since I turned sixteen." Without thinking, she spun around, ripping Josh's wood from her pussy, and faced him. She grabbed his cock and asked, "Can you wait for me to suck this? I want to learn how to do it right."

Josh pressed against Rachael, kissed her, and replied, "Fuck, bitch, that hurt. If you don't break it off, I'll be happy to just keep fucking you."

She popped a kiss on Josh's lips and said, "Damn, I am sorry. If you stop being with Janine, you can fuck me anytime you want."

Josh smiled and replied, "Janine and I never had sex. I just said that to see how you'd react."

Rachael giggled and straddled Josh's hips and lined up Josh's still hard cock with her pussy. She kissed Josh and frankly said, "It hurt a bit that you had sex with Janine, but I remembered- who hasn't had sex with Janine. Honestly, I started this because I wanted to finally experience sex. A science experiment, but I am fucking enjoying fucking, so fuck me. Am I really your girl?"

When Josh was completely back inside her, he said, "I have wanted nothing more than you being my girl since we met at your sixteenth birthday party last year. What we are doing now is a delightful bonus."

She closed her eyes as Josh slowly moved back and forth inside her.  She felt a soft kiss on her cheek. Startled, she opened her eyes with Janine's face close to hers. Janine whispered in her ear, saying, "Fuck, girlfriend, are you finally being fucked?"

Rachael was past caring who was watching. She giggled and moaned, "Mmm-hmm."

Janine turned Rachael's head toward her and kissed her. Rachael could taste what she assumed was cum on Janine's lips. Hearing Josh's moan as Janine kissed her excited her even more. She reached up and held Janine to her. Their kiss became more passionate as Josh pounded Rachael's pussy harder.

Janine looked at Josh and said, "That's it, big boy, pound that pussy. My girl is loving being fucked by you."

Janine was right; Rachael was loving being fucked. The fact that it was Josh made this pounding even better.

Josh grunted, and Rachael felt his cock swell and pulse. The feel of Josh's cum squirting inside her made her cum so hard she screamed, "Oh fuck, I am cumming."

Janine giggled and asked, "Feels good, doesn't it, girlfriend?"

Rachael moaned, "Fuck yeah, and he's still hard inside me. Please don't stop."

Josh was happy to oblige that request.

The next school day, Rachael wasn't hiding under her clothing anymore. She proudly walked down the hall with her arm wrapped around Josh's arm in a dress that made everyone look twice. She actually found the jokes whispered about her last name funny.

Josh, seeing her laughing, asked, "What's so funny?"

She hugged Josh's arm tighter, kissed him, and replied, "The guys are saying they heard Cummings cumming more than once."

Josh laughed, kissing her back, and asked, "You want them to hear you again, don't you?"

Rachael replied by asking, "Yes, does that bother you?" Rubbing Josh's cock through his pants for everyone to see, she continued, "And I am ready to taste this."
