<human>: Recently an older married man in an open relationship showed interest in me and we hooked up.  My boyfriend and I are now exploring the idea of making our 2yr relationship an open one.  My only concern is that I only want to have sex with that one person I hooked up with previously - who was my boyfriend's older brother who is currently in an open marriage.  My boyfriend knows everything that happened and we are absolutely great at communication.  He's still thinking about the concept while I'm completely intrigued by it and definitely want it.  Do y'all think I am going into this with the wrong intentions?

Can you give me the gist of the text in a nutshell?
<bot>: I (23f) want to make my two year relationship with my boyfriend (21m) an open one because I hooked up with his brother and loved it.  Is this going to a problem if we do open our relationship?
