A kind meeting with Marina Shiraishi from HR helps me through a crushing workload, and I gradually fall for her despite knowing she is married. When she invites me to dinner at her home, our growing intimacy leads the lonely, sexually neglected wife to kiss me. We begin an affair, meeting once a month whenever her husband—my manager—travels for work. Marina has become even more sensitive after giving birth, and I greedily play with her gorgeous G-cup breasts before repeatedly fucking and creampieing her irresistible body.
