The Montgomery glands are small protrusions located near the nipple. These sebaceous glands secrete pheromones that spread across the areola. Although each protrusion is small, stimulating them can concentrate sensitivity from the entire areola to the nipple, ultimately leading to full erection. Compared to directly stimulating the nipple, this method is more comfortable and pleasurable. The protrusions have reached their historical peak! Let's enjoy the S1 female performer's movements as she shakes her large breasts and ignites with a sense of novelty.
