[MF] The time I fuckedmy brother’s ex

Disclaimer: I’ve never written one of these but have been reading for a long while and jacking off to these stories. Thought I’d give one of my more recent situations a go. Its pretty long and might make you bored but if nothing else writing this in my mind helps me rehash some good memories

When I was young about 10 years old, my brother had a girlfriend(lets call her Sarah). They were together a few years – not sure how long but long enough for me to hit puberty and develop a crush on Sarah. I’m 30 years old now so my memory is hazy on details of his and her relationship. She is probably late 30’s now or maybe even 40. These encounters happened this year maybe 2 months ago or so. I think about it everyday. Never plan on telling my brother or any of my family, as I believe my brother has moved on but my family never liked this girl.(and even though I love my parents they tend to be judgmental and hold grudges) My brother is now married to someone completely different and has 2 kids.(so he shouldnt care right? IDK – dont plan on finding out LOL)
