I didn't know that was the word for it, but I realised it had something to do with the sense of smell. My goodness, I LOVE smelling a man's hairy armpits. That MUSKY ODOUR!
Olfactophiia ( being turned on by odours, especially body odours is a massive part of group sex. You have the smell of sweet, cum, just fucked holes, maybe even piss. I knew 2 ladies (who unfortunately have passed) who had a small private dungeon space in their house. Entering that room was heaven. You could smell the sweat, cunt, piss, fear, cum, smoke, leather, pvc.....a special place!
God yes! Smelling his odour and feeling his cock working in me then that stretch as another joins it. So good if the top drips sweat on me as he works me. Used like a human flesh light LOL
