At Last I Can Tell

Back in the early 70’s when I was 13 my parents went on holiday and I stayed with my eldest brother and sister in laws.
I had a massive crush on Pam so it was a great opportunity to wank with her used panties which I would take out the wash basket in bathroom.
A few mornings later in the middle of a great wank thinking everyone had gone to work in bowls Pam with just a short nightie and squats on pan for a pee, she opens her eyes and shrieks, I panic and go up to her pleading sorry with a massive hard on in her face, she does what comes naturally and takes my cock in her mouth, and I cum virtually straight away, she swallowed the whole lot , I remember being impressed with the amount of sperm. She says sorry and it must never happen again, I agree but it had broken the ice between us and within an hour I was in their bed losing my virginity to Pam.
Pam went sick from work for the rest of my time there and I now know I got her pregnant during that time, my 2 nieces and nephew are my daughters and son as my eldest brother had count probs, even today we still have a session when the opportunity arises Pam is my 2nd wife
