My sister got pregnant with my child and we are quite happy now

When I was young I masturbated to the fantasy of having sex with my sister. We grew apart when we became adults and started to live our separate lives, I never told her about my fantasies.<br><br>My sister's first pregnancy was difficult and she was told by her doctors that she couldn't conceive again. My sister and her husband wanted a second child so they decided to hire a sperm donor.<br><br>I had already figured that if I ever had a chance to have sex with her, I would. The idea of my brother in law raising my nephew repulsed me. It didn't take long for me to ask my sister if I could be her donor. I talked to her about my fantasies and the fact that I wanted to have a son and we eventually made an appointment to do the deed.<br><br>We met at a hotel and we did it. We took a few days to get to know each other again. She got pregnant and last week our beautiful son was born. Being a dad is great and I'm so happy that we've had this chance to make our family closer.
