A woman writhes in pleasure as a fist is thrust into her vagina and anus. In contrast to the women who swallow the fist without a second thought, the reaction of the girl who puts her fist in someone else's hole for the first time is also amusing. Squirting juices and intestinal juices spurt out of the holes that have already been developed. With ecstatic expressions on their faces, they are immersed in a pleasure that only women can know.
