you know, i don't save my porn, but... i managed to find the couple of best vids i found before in this category. both of them are lacking in some way... but they're kind of close enough to get the gist

this one is actually a married couple fucking in some kind of ceremony on stage. it doesn't have the audience involvement but there's something hot about the sheer number of people there just to watch. note that this is part 1 and 2 of a three part series: https://www.xnxx.com/video-uu55hd6/pornovatas.com_romantic_real_public_sex_big_natural_tits_vs_big_dick_by_victor_bloom

this one is just a dude fucking a stripper on a table and there's like... one guy watching and plausibly an audience. again, not too much audience involvement, but it's hot the way he fucks her just SO GOOD up there for the crowd: https://xhamster.com/videos/gorgeous-stripper-gets-eaten-out-and-her-pussy-filled-with-hard-cock-xhMEdlU

alright, i know you want an example of the audience involvement... the only thing i got is this insanely hot gif i think i downloaded off redgifs. and thankfully, it's still uploaded there with the same filename lmao: https://www.redgifs.com/watch/unrulyvalidgazelle

anyways, if there was a vid that like... combined all of these... idk if it would be my ideal porn vid but certainly scratch an itch that's otherwise hard to get! and if they're underwhelming, it's cool. hope they're at least somewhat enjoyable though
