Cheating on my [F] Boyfriend with someone who just became a dad [MF]

So I’m a big fan of reddit and god knows how many stories from here got me off but this is actually the first time I’m posting something of my own.

So a little backstory I’m a 24 year old woman who’s been living away from home since I was 18. Since moving to another country for school I started exploring more and had a lot of sexual encounters but this one is my favorite.
I used to work at a nightclub with this guy let’s call him Eric. Eric was three years younger than me and was in a relationship with a girl who was also pregnant. At work we would flirt a little nothing serious just some innocent flirting. At the time I started dating this guy and a week or two later i was also in a relationship.
