Is it normal that I love my girlfriends ass smells?

I used to work with my ex at a dept store. And we would go in the dressing room and or bathroom while it was slow and have quickies, or just oral sometimes, she would wear tight pants or short skirts to tease me . She was a petite Latina with a tight bubble butt, one day she said she didn't have time to shower and had just taken a dump but wiped really good I didn't care I buried my nose in her butthole and inhaled like it was my last breath!! Then dug my tongue as far up her rectum as I could and ate her ass like a hungry dog, after she came she would blow me and swallow my load back to work we went with the smell of her ass on my nose she would also smell my ass she came so hard from doing that
