I created a reddit account just to tell this story of how I got my first ever gangbang with 3 guys in total. Not a lot in term of numbers but it was my first ever still.
At that time, I had 2 FWBs, who are good friend with each other and I have done plenty of 3somes with them, proposed to me randomly if I would like to have an extra guy as a gift for my birthday. It was something that I never actually was planning to do, never really had the thought of doing that in the future. But with my adventurous mind, I accepted.
