Timid Brother

Long short my only brother the older of the 2 of us was very timid. But very smart and finished university 3 years ahead of people his own age and got a very good job. I on the other hand aren't as smart as my brother and finished 15th in my year and got a good job and everything was going well for me until 2019 and the company, I worked for crashed and went bust. Suddenly out of work and hardly any savings I was in a pickle as they say. My only salvation would be my brother and of course he took me in, and I was looking for work along with everybody else that had lost their job. I had 2 choices move to another city in the hope I might find a job or stay put and wait it unemployed herd thinned out a bit. I decided to stay, main reason I had a place to live, and it wasn't costing me any money as I'm family. Anyway, I thought the new year my luck would improve and 2020 came and things looked to be improving. Then Covid hit and a lockdown quickly followed, I had been keeping the house for my brother doing the cooking. I wasn't dating and stayed home and kept myself fairly satisfied masturbating. Then wearing earphones while listening to music I walked into the bathroom to get any laundry and caught my brother masturbating. Normally I would've made fun of him, but my eyes saw that massive thing he was stroking. I now knew why he was so weedy in his build 5'4" and skinny all growth when to his penis. I thought it's a wonder he hadn't fainted, filling that monster cock with blood should've made him pass out. Once I had left the bathroom, I had to masturbate myself. But satisfying myself wasn't working, I wanted to at least try his cock once. So, I went to my brother and asked him to fuck me, which shocked him and myself as well. It was like an out of body experience I was across the room and watching myself asking my brother to fuck me. With me pressing him he agreed and fuck me he did, turns out I was his first real woman. He had tried blow up dolls before, but his massive cock had split them. Of course, once wasn't enough and I started to sleep with him. Then I messed up and I got pregnant and so got test for problems with the baby nothing was found and so I had the baby. Only our mother (widow) knows my brother is the father of her first grandchild. My brother isn't a social person, and his employers didn't know much of his private life. So, I became his wife except for actually marrying him and wearing my mother's rings. They now think I'm his wife and I was also hired by my brother as his assistant I was qualified and being his wife was with him 24/7. He had gotten a promotion which required him to travel and me as his assistant made it easier for him to travel. We can leave our son behind as our takes great care of him. Also, I got pregnant again due early March. No problems shown in any tests, to my mine and mother's delight it's a girl.
