This beautiful girl shows an abnormal reaction in the deepest part of her vagina, around her cervix. The cock plunges into her tightly and repeatedly, pistoning her until she arches her back and trembles in ecstasy, and then he finishes her off with an incredible ejaculation into her fully open cervix. At that moment, her face is a pathetic mess, and she is no longer the Saki-chan you all know.
