How I started to fuck [M]y brother in law [F]iancé/cheating

Throwaway for obvious reason

Me and my wife lives in an apartment building. Awhile after we moved in. Her brother and his fiancé moved in 3 floors below ours. She’s 5’3 looks 8/10 body 10/10

It all started on her social media account. As she was venting about issues in her life. I figured since we were all very close I’d message her make sure she’s ok. We talked about what was going on in her life, nothing too crazy. She made me promise not to tell her fiancé that she talked to me about her issues. After a few days of texting. We started flirting a little. One Friday I was having a bad day. She told me she was home alone if I need a hug I can come down. I took her up on her offer. Came down for my hug then I left. I message her told her and how great she smelled and how good that hug was. She said you can always come down for another. I wasted no time this time I squeezed her tight. A few days went by she told me she’s home alone and her fiancé won’t be back for a few hours, she feels like cuddling. I went down she was on her couch with a pants and a bra on. I dove straight into her arms. As we were cuddling she said too bad I don’t cheat or we could’ve worked something out. Before I know it she took her bra off and I was sucking on her perfect handful of tits. She then said the couch is uncomfortable. Let’s go to the bedroom but no further then this. After a few minutes on the bed. She said to me ok just once stick it in just once I can not control myself anymore. She let out the loudest moan I ever heard. Then I told her let me go back to my apartment to grab a condom. I left she texted me not to come back down. I came back to make sure she was ok after no respond. I guess she was feeling guilty as she was crying when I came back. We still haven’t stop flirting/texting each other. Few days went by and she asked me to come over. When I walked in her door she was laying on the floor I came lay next to her. She whispered in my ears let’s finish what we started, fuck me!

This is how it all started. I probably fucked her at least 20 times in a month for the next 2+ years. Some real interesting stories if you guys are interested. Sorry for the poor grammar
