I became his Sex Toy

My brother 28 is a quiet person, who I thought was a nerd. He didn't play sport as far as I knew and seemed to study instead of dating. Not that I was keeping a close eye on him, I was too busy enjoying myself. If I'd kept a closer eye on him, I would've found out a lot sooner he did play sport. Just not the normal sports like football and basketball, I was use too. He played a foreign football called rugby; he would tell me after I found out our football was too tame and boring for him. Because of his lean figure I thought he was just skinny, but it was all muscle. Passed out second in his year from university and got a great job straight away. I left university two years later in the middle of my year graduation class. My first job wasn't that great and didn't last long, our mother had passed away when I was 14 and our father died of pain killers, alcohol and the resulting fall down the stairs when I was 20. So, it was just me and my brother left, we'd cousins and aunts and uncles who we rarely saw. After losing my fourth job and still single, I needed a place to live and asked my brother to take me in, he did. He seemed always busy, and I thought it was his job, but it was his lifestyle. He kept private even from me, I hadn't shown any interest in his life growing up and he thought I wasn't interested in knowing about his life. As I couldn't find a suitable job, I stayed at his apartment alone a lot of the time. My brother got promoted and was entitled to an assistant, but it also meant relocating to another state. With no job and nothing available that suited me I went with him also. In the new state he bought a house instead of getting another apartment. It was then I found out about his passion for rugby and watched his first game with a new team, it was a brutal game, and I was shocked how rough it was, and with no protection worn. Some players wore padded head wear, they had concussions before I was told and wore them as protection just to be safe. No helmets or padding worn otherwise; the game didn't stop it was full on all the time. My brother wasn't the nerd I thought him to be. Anyway, as I'd the same surname other players thought me to be his wife. Then as my brother still hadn't gotten his assistant and had to travel short notice. He took me with him to act as his assistant, we shared the same room. Nothing happened sexually on the three-day trip, except I saw him with his shirt off and well-muscled body. I was impressed but had already realized he was fit from watching play rugby. After our return another job away came up and I again went with him, this time he offered me the job permanently and I accepted it. but we partied a bit too much and became lovers. No worries about pregnancy as I was on protection, but I really enjoyed sex with my brother as he was the best lover I had so far in my view. Of course, we didn't at the once it became regular for us to fuck and as I thought of as his wife due the same surnames, we could show affection when out and about. After a couple years of our sexual relationship and me seeing other women with children, I asked my brother to get me pregnant. He thought about it and agreed, we now have four children. Planned to have two but had two boys and I wanted a daughter, so we tried again and got twin daughters no health problems with any of them. I do anything sexual my brother wants as I'm his favorite sex toy I believe, but he doesn't hurt me and makes sure I enjoy our sex together.
