I didn't really know I had an underwear fetish until last year. I met up with someone off grindr and who asked me to his place for a blow and go. When I got to his living room he was standing there fully clothed. I went over and he took me by the hair and had me get down on my knees. He undid his belt and loosened his zipper and pushed my head right into his bulging white underwear and told me to sniff it and lick it, I kinda liked it. After they came off and a little face-fucking happened one thing lead to another and my hands were loosely secured behind my back with his belt and he was shoving his underwear in my face and then just put it over my head! At first I was like "WTF?!" then it started to turn me on a lot. Needless to say, I ended up face first into his couch as he drilled me, taking my head up and down by his tighty whities and I fucking loved it.
How would everyone else react in that situation?
