just this one time thing tho

so i'm nonbinary and in my 20s and been with my partner for a few years now but we're really different in the bedroom so i always wanted to try something that's not our thing like this bondage stuff. i'd been secretly reading about it online forever but never said anything to them because they have very strict rules about limits you know no pain or anything like that and i've just had these fantasies for a long time. one night when we were both drinking at the bar and having fun this other person came up to me, they saw my tattoo of this rope thing and started talking about it and i dunno i got really into talking with them too it was so rare for someone else to understand and like the stuff that turns me on. next thing you know we're at their place late and i'm feeling adventurous and just go for it. i let them tie me up and fuck me however they wanted and it was amazing. felt so alive but also kinda guilty afterward because my partner trusts me so much. not sure if i can do this again without hurting anyone.
