>>89627736There's a natural human response to showing armpits that shows vulnerability and submissiveness. Makes male reptile brain go brrr. That's why you see models and stuff commonly pose with them up. They accentuate and enhance the curve of the breast line silhouette which is attractive. Women soft and curvy (bust-hips), attractive. Pheromones play a role too, natural smell/animalistic. A deeper fetish idk, nearly everything can be taken to an extreme. I like pits but I don't go as far as wanting to fuck them with my pp.
