WANZ-386 Miho Sakaguchi as my uterus ejaculates

This beautiful girl exhibits an abnormal reaction at the deepest part of her vagina, around her cervix. She repeatedly thrusts the piston through her small penis and finishes it all at once with a tremendous amount of ejaculation into her cervix, which is now fully dilated due to the orgasm that keeps her mouth loose. At that moment, she stared at her ceiling and screamed, no longer being the Miho-chan you know.
