Ten year old Adam stood in the hall of the house he had lived in all his life. It was dark, and he wasn't sure what had woken him up, but on his way to the bathroom, he heard noises from his mothers room. He tip-toed to the room door which was slightly ajar to investigate, and was shocked at what he saw.

The first thing he saw was his older brother Derick laying on the bed. Derick was a good looking boy, he was tan practically year round, had short blond hair and light blue eyes. He also played sports and was fairly muscular. As Adam stepped a little closer, he couldn't help but let his jaw drop open. His Mom's boyfriend had Derick's legs on his shoulders and was shoving is dick in the boy's ass. Their Mom was straddled over Derick's face, and his tongue was going a mile a minute.

Adam new what sex was, once he and Derick had jacked off together, but he had never seen anything like this. His cock was hard in his small batman briefs, and he had started to play with it. With one hand he pulled up his t-shirt, holding it under his chin, with the other, he freed his small cock and began stroking it. He watched as his mother squirmed around over Derick's face, leaving a glistening trail all over him, and he saw the man's mouth move as he moaned in pleasure. The man had his hands on Derick's thighs and with a slight arch in his back was hammering his way into him, all the while Derick was jacking his own dick.

Derick started moaning into his mom's pussy as his strokes got harder and harder until finally a ball of white liquid shot from it's head. That was all it took for Adam, he had to bite his lip to keep from moaning aloud, but he managed as he dry cummed really hard. He could hear how loud he had started breathing, so he didn't stay to watch the end of what was going on in his mom's room, but that wasn't the end of his shocks for the night.

Moving down the hall, walking backwards so he could keep an eye on the door, he didn't want to get in trouble for watching them, he heard a voice from behind him whisper "don't hit me". Looking back, he saw his six year old little sister standing at his doorway. From where she was standing, she would have seen him the whole time that he had his cock in his hand.

"What are you doing out here!" he whispered at her in return.

"Seeing what is going on... What were you doing?" She asked, her eyes locked on his underwear.

"Nothing, go to bed" he said, getting a little bit annoyed with her standing there.

"Not until you tell me what you were doing" She said folding her little arms and firmly planting one foot on the ground. He couldn't help but think of how cute she was. She had long brown hair and while not fat at all, was large for her age. She was still years away from tits, but she could almost pass for a seven or eight year old. She was wearing a pink t-shirt and white short shorts, her favorite sleeping outfit.

"Britney, I'll tell mom."

"If you tell mom, I'll tell her you were outside her room messing with this" She said reaching her hand forward and rubbing it for a second before Adam had the chance to react. He nearly jumped back, and were it not for him forcing himself to stay quiet he probably would have yelled at her. As it was, in the interest of not getting caught, he stood there as she touched it. He had never thought of her in this way, but it took seconds for it to grow hard under her touch. No one had ever touched him there, and he could believe how good it felt.

As it grew it was obvious she was trying to figure out why something soft was getting hard. "I'll show you" he said, as he pulled the underwear down in the front and let his cock again plop free.

"Why is your thingy so hard?" she asked looking at his face, her hand hanging in mid air, not sure what to do with it.

He solved it for her by taking it and putting it on his dick before saying "Cause it likes you"

She began rubbing it a little bit, but not knowing what to do he had to show her, but first, they had to get out of the hall. He led her the rest of the way into his room and shut the door. "Come on" he said walking to the bed and taking off his shirt and underwear, now standing completely naked in front of this little girl.

"Your naked!" she said in a loud whisper, as if he wasn't practically naked when his cock was in her hand.

"So!?" he said back, motioning for her to come over to him. He tugged at her clothes until she started to help and then they were both naked. "I'm going to show you what was going on in mom's room" he said and had her lay on the bed. Carelessly he raised her legs up on his shoulder and clumsily started sliding his boy cock up and down her pussy slit and ass. He wasn't really too sure where it was supposed to go, but as he pushed, her pussy started to open up a little bit so he focused there.

"That tickles" she said stifling a small giggle. Placing his hands on her thighs where the man had his hands on Derick, he began pushing his way in. It was so tight and so moist he could barely contain himself. This was way better than his hand. As the head pushed in, causing them both to loose their virginity, he lost control and jammed himself all the way into her, dry cumming on his first and deepest stroke. She cried out once, but only once, it was obvious that she was biting her lip. As he dry came in her, he was taking baby strokes in her, not able to stop to see what was hurting, but he did notice how moist it felt and it made it all that much better. It wasn't until later that he saw blood, and later still that he found out why she had bled the first time of many, but those are stories for later.

This is my first story, so I would love to hear what people think, let me know if you like it and I will surely write a part two!
