The second part of this story was inspired by 2 emails I received by anonymous senders.

It had been about 5 months since the day in the spare bedroom with my sister. She caught me hiding behind a wardrobe as I watched her trying on her Wedding night underwear.
Her new husband called me unexpectedly one Saturday afternoon and invited me down to their house for the weekend. Neil, her husband was going to be away that weekend working and they wanted me to come down for a visit and keep Angela, my sister company. He seemed highly excited as we talked then he broke the news. I was to be an uncle. Angela was pregnant.
The weekend had arrived so I got into my car to drive the 100 miles or so to my sisters house. As I drove I remembered the day with my sister. Tasting her, kissing her, shooting my cum into her... Could it be mine, the baby?
The journey too around 90 minuets, no real busy traffic, no hold ups. Neil saw me pull up outside the house, he shouted Angela and they both came out to greet me.
Angela was glowing as all women do when they are pregnant. She was wearing a long blue maternity dress. Her breasts had swollen, making them bigger than they already were. Her hair was a little longer also, gently cascading over her shoulders. She ran up and hugged me tight.
"I've missed you" she whispered to me. "I've missed you both too mommy" I laughed.
I brought my weekend back into the house and made myself comfortable.
"Well I can make a move," said Neil "If I set off now I can miss the traffic." Neil grabbed his bag, kissed his wife and left, leaving me alone to look after my older sister for the weekend.
We sat and talked as we ate the dinner she had prepared for us.
"Mark, there is something I need to talk to you about" she said nervously " Remember that day in the bedroom?"
"How could I forget" I replied. "It was awesome. I feel a lot closer to you now"
"Mark, I think the baby is yours and I don't want Neil to ever find out," she said.
"But I want to do it again. It was the best sexual experience I have ever had. You have no idea how many times I have lay in bed jerking off to the though of you and I making love" I answered.
