>>39224860Too much of a good thing is generally a bad thing, especially when it comes to smell and food.
Regardless, that's not how it works. Warm air rises up, so all you'd be able to smell if her feet, and I'm not a footfag.
I don't wanna get into pressure and how gasses move and displace each other in the air, but in short, simply being larger will not increase odour intensity as much as you think.
