I slept with my brother's best friend and now he won't leave me alone.
What was your reasoning for sleeping with him?
He's a good person, funny, and charming as well.
It can be easy to fall for someone that you spend a lot of time around, but if that person is the friend of a sibling then it's better to avoid indulging in such feelings. Sleeping with a friend of a sibling can cause conflicts in your sibling's friendship.
Fuck, I didn't think about it. I don't want to ruin their friendship.
I totally get your attraction, but I'm glad you realize the potential negative consequences. Moving on and not sleeping with your sibling's friend is best for all parties and it will minimize potential problems in the future.
