CEMD-668 The shut-in me who tempts my mother-in-law Nagasaki Yukine with sex every day and trains her with in-and-out

Harto-kun, my stepson who was supposed to go out with my husband. One day, due to my husband's fatigue from work, my 'perverted nature' surfaced because of my continuous sexual frustration... I found Harto-kun's underwear in his room and became aroused by the scent of a young male, losing myself in masturbation. Unaware of Harto-kun returning to pick up something he forgot, I was even being recorded without knowing it... I had no idea. Since then, Harto-kun started blackmailing me with my masturbation video and forcing me into fellatio. Fearful of telling my husband, I let my stepson do as he pleased, even experiencing the 'squirting' technique from AV productions, making me feel incredibly good... Before long, I began to vent my frustrations with my ED husband using Harto-kun's erect penis and eventually became addicted to the forgotten pleasure of 'raw insertion'... From then on, our marital bedroom during the day turned into a room for incestuous sex with my lustful stepson...
