This happened about 5 years ago and the title is a bit clickbaity. We’d been close friends for years, not like intimately close or in love, but always sharing everything (including sex and relationships related), playing video games together and sometimes we had lanparties at her place, previously with multiple people. She lived 2 hours drive away, which for us Europeans is quite a long distance.
She’s ~160cm tall, a bit chubby, white elbow heigh hair and rather large breasts.
That summer I brought my desktop and we had a 2 person LAN-party weekend at her place. She had broken up with her boyfriend a couple of months earlier and now relied on Tinder and two FWB’s for her sexual needs. She complained to me how Tinder was dry, the other guy was so bad she didn’t want to bang him and the other guy had started dating (she was strictly monogamous and wouldn’t bang anyone who’s taken).
