WANZ-428 Misato Yoshiura as my uterus ejaculates

This older sister has an abnormal reaction at the deepest part of her vagina, around her cervix. - She lost all trace of her elegant demeanor, and was unable to stop herself from cumming to the point where drool dripped from her mouth, and finished off her cervix, which was now fully dilated, with an incredible amount of ejaculation. - At that time, she started howling all the time and was no longer the older sister you knew.
