Nearly a year after marrying my kind and wealthy former coworker Satoshi, I still have a strained relationship with his adult son Hanzo. Sex with Satoshi has also become mechanical, performed only to make a baby, leaving me deeply frustrated. Unknown to me, Hanzo has watched my dissatisfied expressions and every dull encounter with his father. At last he confronts me with his innocent but overwhelming lust and erect cock, wondering aloud what would happen if I took his instead. Soon, each round of baby-making sex with my husband is followed by his insatiable adult son fucking and creampieing me.
