Armpit sniffing fetish - He can't stop

I love to listen to music and dance! It makes me feel happy. I was just dancing when he came into the room. I told him to go away and not bother me but he started kissing. I thought he wanted my ass, but today he went straight for my armpits! It's crazy. I don't understand. He smelled them and sniffed them and wouldn't stop. At first, it tickled me and I wasn't sure what to think. Then it started to make me horny. Then it was really fun and we were just rubbing together as he buried his face in my armpits to smell as much as he could.
