caught in the act

so this is a thing ive been into for a while now but my partner doesnt know about it and honestly i dont even think she would get into it. im in my late 20s and have this really intense fantasy of being tied up and fucked hard while someone else watches me, maybe touches me too. i know its not the kind of stuff most people talk about easily but its just so fucking hot for me. one day i was at a friends place and they had some hidden cameras set up in their bedroom which we were both cool with as long as it stayed private between us. well turns out there was this other guy who knew about our arrangement too, nothing major, just the setup of the space. so one night when my partner and i came over he snuck into another room while we started getting pretty wild and things heated up quick. next thing you know hes watching from behind a curtain and at first it made me feel weird but also kinda turned me on seeing him there like that. before long im begging my partner to tie me up and fuck me super hard, knowing this other guy is in the room too, just out of sight but totally getting off on us. i know its not exactly normal but im so turned on by this dynamic, feeling used for someone elses pleasure too as well as our own, that when we got caught it wasnt really a big deal to me, just an intense new experience. my partner knows nothing about any of it and honestly might be freaked out if she ever found out but im not worried cause its all consensual between adults. i mean obviously id never do anything behind her back again but this was one time that slipped through the cracks. now whenever i think about being watched while im getting fucked my heart races thinking of how amazing it felt and just hoping we can find a way to try something like that again without risking our relationship.
