Sniffing underwear/jockstraps, etc. Just faceplanting into a hot guy's warm crotch and going wild. #dontjudgeits4chan
I guess facesitting also counts..
Don't y'all have had enough of this fetish from watching those straight men doing it for money from one of those studios? Go browse their sites and fap to all those arse rimming and what not till you can no longer fap.
