Kasumi introduces Eri, a pale, fresh-faced married mother who has barely known any man besides her husband, for her first affair. The young wife looks like an adult college student, but her high sex drive leaves her unsatisfied with marital sex alone. She is shocked and thrilled when another man’s huge cock enters her for the first time, then screams, writhes, and cums repeatedly through the rough sex. The mom-friend hookups are far from over.
