My sister Tracy and I have been best friends for a very long time. We had a very rough childhood. Our father was an alcoholic and he came home on more than one occasion late at night, drunk, and mad as hell about something. One night when Tracy was 8 and I was 9 my father came home around 2am. I nearly jumped out of bed when I heard the front door slam hard into the wall. I knew father was home and my heart began to race rapidly. I pulled the covers over my head to hide. Just then I heard the door to Tracy's room across the hall open hard into the wall. Tracy screeched and I heard father yelling at her for leaving her "damn doll lying on the floor that he was trying to walk on" and then I heard the slap and the door slamming closed.

This kind of stuff went on almost every night. Mom threatened to leave him on more than one occasion but he would just slap her around and tell her she didn't have "the balls to leave the money he was giving her" and that was the only reason she stayed around.

Mom had done very well in her life up until she met father. She had worked her way through the ranks of a major Fortune 500 company and was just about to be offered an executive position when they met. He brought everything to her life that she didn't already have which included love and sex. They had more of a sexual relationship than anything else and by the time their one month anniversary rolled around she was already pregnant with me. Father was very happy when he heard the news and told mom that he had to marry her now that he had made her pregnant. They walked down the aisle when mom was six months pregnant and by the time I was born mom had quit her job to be a house wife. Father told her "that as long as she was his wife she was not going to work. A woman's place was at home, pregnant, in the kitchen." Mom wasn't exactly thrilled by his take on women but one month after I was born mom was pregnant with my sister Tracy.

When mom was in the hospital giving birth to Tracy she had them tie her tubes because she knew if she didn't she was going to be there every nine months having a baby. She never told dad she got her tubes tied which got her slapped on more than one occasion when she didn't get pregnant. When he eventually did find out he beat her up so bad she was in the hospital for a week. During that week dad brought more than ten women to the house and they had sex everywhere. He told me one night while he was having sex in the living room while I was trying to watch television that he was "proving his manhood to these real women." His manhood was proved when six of the women wound up pregnant.

On the nights that father went to Tracy's room and slapped her around she would come running into my room crying. We stayed up many nights holding each other scared that he would barge into my room and slap us around some more.

Two nights after my sixteenth birthday Tracy came to my room, crying. I asked her what was wrong and she told me she was scared that father was going to slap her again. I held her close in my arms and told her everything would be alright, although I was just as scared as she was. After about an hour Tracy began to calm down and I wiped the tears from her face.

Tracy laid her head on my shoulder and I ran my hands through her long soft brown hair. She looked into my eyes and I could tell she was hurting. I was her brother and I wanted to protect her and make her feel safe and secure. I leaned into her warm body and kissed her softly on the lips. Tracy neither kissed back nor did she try to stop me. She parted her lips just enough to allow my tongue to enter her mouth. I kissed her for a very long time and after awhile she began to kiss me back.

I laid her down on my bed and held her in my arms as we kissed and explored each others bodies. Tracy ran her hands down my back as I felt my erection start to build. I placed my hands on her small butt and pulled her hard into my crotch and she smiled as we kissed. I took that as my cue and rolled Tracy onto her back.

I knelt in front of my sister as I slowly unzipped her pants and pulled them from her body. I saw her body start to shake as I released my hard member from the confines of my pants. I slid Tracy out of her soft pink panties and softly kissed her on the lips as the head of my erection slid into her warm wet vagina. I stopped to enjoy the wonderful sensation and to allow Tracy to get used to having me inside her. We were both still virgins until I pushed my hard cock into her and felt her womanly membrane pop. Tracy closed her eyes and softly moaned as I took her virginity.

I pushed my cock deep into my sister's vagina and held it there for a few minutes as Tracy and I softly kissed. When I felt her start to relax I slowly began to pull my cock from the depths of her womanly hole and then just as quick began to once again descend. I moved into a slow steady rhythm and before I knew it I could feel my approaching climax. I slowed my pace and told Tracy that I was going cum. She grabbed my ass and pulled me hard into her body as I began to moan. I tried to pull out so I wouldn't cum inside her but Tracy held my ass and my cock let loose inside her warm pussy. I thrust hard into her as sperm shot out of my cock and descended into the depths of my sister's awaiting vagina.

As my climax started to subside my cock started to go limp and slid out of Tracy's vagina without any help.

I held Tracy in my arms for the rest of the night as we both slept. Around 2am our father came home drunk but to our surprise went straight to bed without a show. I whispered into Tracy's ear and told her everything would be alright. She smiled and we both fell asleep.

The next morning I awoke with Tracy still in my arms. My cock had sprung to life and when Tracy awoke a few minutes later I was deep inside her just about ready to cum. She thrust her hips into mine and sent me over the edge and I released another load of sperm into my sister's vagina.

Tracy and I never discussed that night but when her time of the month came and went the next month her period didn't start. I was overwhelmed with joy when she returned from the doctor a few days later with the news that she was pregnant. We told mom the news together and while she was sad that I was the one who had made Tracy pregnant she told us she would be supportive.

Three weeks after Tracy found out she was pregnant father's car was broad-sided as he came home from work and he was killed instantly. We found out a few days later that while father was completely sober, the guy who had hit him had been drunk.

Tracy gave birth to a healthy baby boy nine months later and we named him James Michael Jr.

Shortly after James was born mom was offered her old job at the same pay and she gladly accepted. We moved into a new house one month later and while we had more bedrooms than we knew what to do with Tracy slept in my bed with mom's approval. We have sex on a regular basis and three months after James Juniors arrival Tracy and I made him a sibling.

When mom found out Tracy was pregnant again she approached me and told me she was going to have her tubes untied. Six months later I found myself in mom's bed giving her a load of my sperm as I rubbed Tracy's large pregnant belly. And the next month, much to mom's joy, she fell pregnant with my baby.
