I caught my Aunt update

I've being well trained by my aunt Heather, and she regularly drains me still. But due an error or mistake call it what you will, I got Heather pregnant, with Brennan having the snip years early it was awkward you could say. But Brennan was in hospital had a heart attack playing golf and so the first signs of her being pregnant were missed by Heather. Anyway, Brennan condition got worse, and he passed away and only then after funeral did Heather realize she was pregnant. Heather decided to have the baby as it was healthy and asked my parents could I live with her. It was closer to the university and so they agreed, especially as she was alone and pregnant. Only Heather knew about Brennan being snipped and Heather said she had stored semen for another baby in the future. I sleep with Heather every night and we've since found out my mother her sister knows of the snip and had put 2 and 2 together. But she has decided to stay quiet, as long as we are happy.
