SSIS-799 [Uncensored Leaked] Nipple erection! Montgomery areola gland massage and play sex where breast sensitivity is concentrated Mei Washio

Montgomery glands are small protrusions located near the nipple. These sebaceous glands secrete sexual pheromones and are dotted around the areola. Each one is small, but stimulating them causes sensitivity to swirl around the entire areola, leading to full nipple erection. This feels even better than continuing to stimulate the nipple directly, and Mei Washio's nipples reach their highest point ever! Watch as this S1 actress shakes her big breasts and burns with new pleasure.
