Keeping it in the Family

I'm Ryan 24, I live with my extended family and I'm the only male in the family group. My father passed away when I was 10. The consists my mother Rose 42, her sister Ann 39 and my late father's sisters Rachel 43 and Clare 37 and my sister Robyn 19, cousins Kaye 23 and Paula 22. My uncles are dead or cleared years before. We live in a family group and we all have outside friendships and relationships. But we also have sex with each other in the family group. I have slept with my mother, aunts, cousins and sister on a regular basis for years. It started when I walked in on Rachel masturbating and I asked if she wanted a hard cock. We were joined later by Ann and then it just mushroomed from there. My mother found out I was fucking my aunts and wanted in and my cousins and sister all joined in later. I have a girlfriend Kate 19 and we are getting serious and will soon marry I think. But sex with my family is only for pleasure and is keeping us happy together. They all have lovers outside the family, but sex with family gives that something extra.
