[en] [brother-sister] Amy and her brother, Greg
Almost a year had passed since Amy and her brother, Greg, had their first sexual encounter. Although the encounter was nothing more than masturbating for each other, it still stuck out in her mind as her most exhilarating sexual experience of her life.
As she lay in bed thinking about that night, she remembered how she and her brother had repeated that act several times since, but now Greg had left home to attend college out of state. Now she yearned for more excitement and more thrill. Of course she had enjoyed their mutual masturbation sessions, but it had lost its freshness.
She had ceased her midnight excursions of sneaking through the house naked, as her dad no longer worked third shift. He was a light sleeper, and she thought there was too much risk of being caught. Tonight was different though. Her mom and dad were out of town visiting her grandma.
Danny, her younger brother, was away at summer camp, and her older brother Greg was away at college. This was the first time she had been left alone overnight, and she thought it a perfect opportunity to try something new.
Amy looked over at the clock; it read 12:30 am. She sat up and glanced out the window of her bedroom. Her family lived in one of the quieter neighborhoods in town. She scanned up and down the block and saw no activity. Most of the neighbors were white-collar professionals who usually turned in early during the week.
Amy had entertained the idea of venturing outside without her clothes before but never could seem to work up her nerve to do it. Tonight, I’m going to do it – she thought to herself. She sat there, looking out the window for another minute, just to double-check the street one more time.

Amy got out of bed, and headed down to the living room, wearing only a pair of panties and a pink colored t-shirt. The air conditioning felt colder downstairs than it did up in her room. She could feel her nipples harden in the chill. She walked to the front door and then decided that the back door might be a better idea, since she had never tried this before.
As Amy opened back door, she could see that it was pretty dark outside; there were not many streetlights on that side of the house. She pulled her t-shirt over her head, tossing it on the kitchen table. As she slid her panties down her legs and stepped out of them, she could feel her heart begin to beat harder.
Amy had not felt like this in almost a year, it was invigorating…
Now nineteen years old, Amy’s body has matured quite a bit over the last year. Her breasts had swelled up to a 36C cup, her pubic hair had grown heavier (though she trimmed it regularly now into nothing more than a small patch above pussy), and she now had a curvaceous hourglass figure that the other girls were envious of.
She laid her panties on the kitchen table as well. She could feel herself getting moist between her legs. Ok, let’s do it – she said to herself. With that, she opened the storm door and stepped out on the cement patio. She softly closed the storm door behind her, as it had a tendency to bang if it was let go.
The backyard was surrounded by a six-foot wooden fence, which pretty much shielded her from being seen by any neighbors who were at ground level. However, anyone in a second-story window would have quite a view if it had been lighter outside.
She walked off the patio and into the grass. The grass was wet from the night air, and she loved the feeling of that in her bare feet. A light breeze was blowing, and Amy enjoyed the way it washed over her naked body, like a thousand fingers caressing her all at once. She looked around and saw no lights on in any house. She ran her hands up the sides of her breasts, and across her nipples. She felt a tingle run down her spine, between her legs, and right up to her clit.
Amy let her right hand drop down to her stomach, and then down to her moist pussy. Amy threw her head back as she slowly massaged her clit in a circular motion. She knew if she continued, she would orgasm in a matter of seconds. She forced herself to stop, denying herself the pleasure so as to increase the intensity of her orgasm, when she did let it happen. She wanted to push her luck further.

Amy walked to the gate, slid the latch, and pushed the gate open. She stepped into the driveway. The gravel hurt her feet a little, but in a way, the pain increased her sexual arousal. She closed the gate letting the latch catch again. The driveway was lit by a lone streetlamp at the other end.
She looked behind her and noticed her long shadow. She knew she was quite visible now to anyone who might be looking out a window. Her stomach had butterflies. Screw it – she thought – let them look. She walked slowly down the driveway, towards the street. Each step brought her more into view of the entire neighborhood. She reached up and pinched her nipples. Mmmmm – she moaned quietly.
Amy had become so turned on by this time; she no longer cared about modesty. All that she wanted was an orgasm. The front yard will do – she thought. She walked around the corner of the driveway, now in view of the whole neighborhood, and sat down in the middle of her front yard.

As she lay back, she let out a small giggle. The wet grass tickled her back. Amy looked up at the starry sky as she bent her knees and spread her legs wide open, giving her access to her now dripping pussy. She shut her eyes, oblivious to her surroundings, as she plunged two fingers of her left hand deep inside her, while she stroked her clit with her right hand.
She pumped furiously, moaning loud each second. She opened her eyes wide as she climaxed. Wave after wave of pleasure rippled through her adolescent pussy. Her nipples felt as if someone had put a flame under each one of them. She pulled her legs together, still bent at the knees, with her fingers still inside her as the orgasm slowly subsided.
She felt as if every ounce of energy had drained out of her. Her fingers slipped out of her pussy and down to her side, as she let her legs straighten out. She lay there, staring at the stars, not wanting to move. She closed her eyes, only wanting to rest a few more moments, before she headed back in.
Slowly she stood up. She stood there for several more moments, as if she was unaware that she was totally naked. Amy casually strolled back down the driveway, her perfect ass illuminated by the streetlight, acting as if she hadn’t a care in the world. Back into the house she went, ready for a good night’s sleep.
Amy’s intense orgasm had put her into such a pleasurable state; she failed to realize how loud she was moaning when she came. She didn’t notice her brother Greg who suddenly got back home, stroking his erect penis… Now, it was the perfect time for brother and sister to try each other…
