The term for sexual behavior you described, I believe, is "stealthing". If you search for that, GT has some amateur, not porn-professional collections:

Try and see if these would be any good for you. Can't help you with finding the guy, though.
Also, please bear in mind that there is a related sexual behavior called "pozzing", it is connected to AIDS culture and consists of HIV positive top either not having or removing the condom before cumming inside the bottom's ass in an attempt to spread the virus to him (mind, not always per prior agreement). That often also involves stealthing. This may not be what you are looking for, but if you are interested in that as well (not judging), you can explore that fetish with this collection:

Good luck.
