Lymph flowing through the groin near the crotch. A man gets an erection when stimulated here, but for a woman... the answer is a foot pin! Mayu Minami, Risa Onodera, Rika Mari, and others who have their libido switch turned on by being pushed by the groin at the esthetic, are in estrus so much that they want to loosen their vagina themselves! When you insert it, you will be immersed in pleasure so that you can force your feet to the pin! Tightly stretched and convulsions! Women drowning in climax!
