I love feeling the texture of a womans nipple in between my lips as i start to suck on it and it begins to get hard in my mouth. The feeling of how engorged it is when i bite down gently with my teeth. The feeling of my tongue running across the ridges and bumps of a puckered up nipple. Nipples are an incredibly sexy, erotic, stimulating, and amazing part of a human body. Just my $.02.
