In this adult role-play, I-cup beauty Kyoko has been married to her former boss Jo for nearly six months. Her seemingly happy life has two problems: she still cannot get along with his grown son Shiro, and sex with her husband never satisfies her. Unbeknownst to Kyoko, Shiro has watched her frustrated expressions and every disappointing attempt at conception. He finally approaches her with his hard cock and innocently asks what would happen if she took his instead of his father's, beginning an affair in which he creampies her again and again.
