Kari and I have known each other for a few years now. We initially met when she was taking a class at a community college with my ex. We did a double date a couple times, my ex and I with Kari and her boyfriend. It was always a bit awkward as neither couple seemed to be matched up properly. Kari and I had more in common with each other than either of us did with our partners. It showed, as both of us broke up with our respective significant others.
Kari eventually changed schools and moved to the same town I was in, even renting an apartment a few blocks away from mine. Unfortunately, things never progressed between us. Friend-zone as it may be. We ended up being pretty close friends. We would party and hang out. Occasionally the games would turn to sexual topics. Again nothing came of it, but I learned a lot about Kari.
Kari eventually started dating a new guy, Matt. Typical frat dude. Liked to party, being a student clearly came second. He treated her well enough and she still spent some time with me. She shared some of their exploits and some of their fantasies.
