I posted something short last week about how my girlfriend and I have regular threesomes with her best friend. A few Redditors were curious about how it began, so I made a throwaway account to share more. Gonna warn you now that this post is not going to get to the actual threesome, just the events leading up to it. (And by the way, I’ve tried to make it nice and readable, but the events are 100% true.) If there’s interest, and I have time, I’ll write up a part two.
