My life is just getting better

I'm Andrew and live on a small hobby farm of 33 acre, I was never a scholar and left school and with money from trust fund bought my farm. I don't need to work as my trust fund will look after me, but I do raise a few animals and crops to supplement my lifestyle. I met and started dating Wendy and we got on really well, but she went off to university and the relationship faded. I wasn't in another relationship until one rainy night I got call from Sharon Wendy's mother. Her car had slid off the dirt into a ditch in the rain and as she was only a couple of miles from my place she called me. I'd always gotten on well with Sharon and I went to help her. IU got her car out of the ditch with my pickup and towed it to my place to check it over. As it was late Sharon decided to stay the night and I showed her the spare room. Early in the morning she joined me in my bed and we fucked, after breakfast I checked over her and done some minor repairs and then we fucked again. Sex between us became a regular thing, neither wanting a more serious relationship. But the damage was done, Sharon got pregnant to me and had a son for us. We decided not to marry, but to live together, Sharon had been left pregnant with Wendy and her father departed as soon as he found out she was pregnant. Never trying to contact either of them since. Sharon didn't take any precaution since the birth of our son and is again pregnant and this will probably be her last child. But we are both happy with the upcoming birth of our daughter, Wendy had grown sick of the busy city life since finishing at university and moved back to live with Sharon. She and I soon rekindled our relationship and she and I are marrying next month. Wendy is also pregnant and says she won't take precautions ever again, she also likes sleeping with Sharon and me and doesn't see me fucking her mother as a problem. So we are all living together happily and I'm enlarging the house.
