My sister inlaw

What happens when your brother is firing blanks.

My brother and his wife live in city out in the country. While I live in a suburb not far from the beach.
One weekend my brother and his wife came to visit and stay the weekend.
We had dinner and we are sitting around having a few drinks. My wife Sarah went to bed and my brother went to the toilet. When Marsha his wife told me that my brother was shooting blanks. She has asked him to put a condom on and after he had cum. She removed the condom and his cum was clear.
Marsha had seen quite a bit of cum shot by other guys and some in pornos and knew it should look a creamy white colour. At least as long as the sperm were alive and moving.
An hour later I watched as Marsha poured more drinks into Henry my brother before taking him to bed. I went to check up on my wife she was snoring sound asleep.
Henry blacked out as soon as his head hit the pillow. Marsha and I were in the loungeroom, and Marsha told me she wanted to have a baby and wanted my help.
I must admit I did like Marsha, so I agreed, and we both stripped off. I looked at her she had bigger tits than my wife, but my wife's areolas were a little larger. Marsha had shaved her muff.
Marsha dropped to her knees and took my cock in her mouth. She was better than my wife.
Then she lay on the couch with her legs spread and I went face first in there. Then I fucked her. I don't know how long I lasted I was a little drunk at the time. But after a bit of a rest, I bent her over and took her from behind cumming in her a second time.
Two weeks later I took the Friday off work and drove to my brother's place while he was at work.
We went to town on each other. I fucked her on her bed and after I had cum in her she lay there with my cum all over her pussy as she used a vibrator on her clit to get herself off. I fucked her second time after watching that. She told me she was going to fuck Henry to let him think it was his if it worked.
This went on three more times before I got the text success. I was a little bummed out not getting to fuck Marsha.
I still saw my brother and Marsha from time to time and watched as her belly got bigger and bigger.
Henry got really excited he was about to become a father. At that point my wife went off the pill and next thing I knew she was also pregnant.
Marsha ha a little girl she called Gwen, and we had a son we called Jayden.
Three months after Gwen was born, I get a phone call from Marsha she wants another baby. So, I go there on the Friday, and I like her new areolas bigger and darker and when I sucked on her tits, I got milk she was breast feeding our daughter.
Once again, every second week I took the day off to fuck Marsha. This time it took five visits to get her pregnant again. Once again, I was sitting back watching her use a vibrator on her clit. To tease me she started putting the head of the vibrator in my cum and then licked it off. Then Sarah wanted another child, and I was soon working on that. Marsha had given me a taste for human milk, and I had started sucking on Sarah's breasts even before she asked for another child.
When visiting my brother's place Marsha would go into the kitchen and squeeze out a small glass of milk for me to drink and no body caught on.
