>>90841325For me I'd say it's the thought that it's your natural/primal/base scent. That it's yours and only yours. That it's so alluring and potent that it gets in my head enough to make me fuzzy and hyper fixate on you. That heady musky scent, so heavy I could practical taste it on my tongue, taste you. Then there's a dominance aspect to it, if you're huffing my balls the fact that you are down there and liking it and even getting off to it , that's incredibly hot. Then you can have a bit of it be about being territorial/possessive, imagine having your lover smell like you so strongly that everyone knows who they belong to, claiming ownership. I'm sure you can reverse all this if I'm the one sniffing you, it's what I fantasize about sometimes anyway
