Extremely erect nipples! Focused stimulation of the areola glands during intercourse, rubbing and playing with them. (Washio Mei SSIS-799)

[Montgomery glands] These are small bumps located near the nipple. These sebaceous glands secrete pheromones that are distributed throughout the areola. Although each bump is small, stimulating them concentrates sensitivity from the entire areola to the nipple, ultimately leading to a full erection. Compared to direct nipple stimulation, this method is more comfortable and pleasurable, and Washio Mei's breasts have reached an all-time high! Let's enjoy the S1 actress's figure as she shakes her large breasts and burns with novelty!
