Atsushi has a forbidden physical relationship with her father's remarriage partner, Rei. Her lust for Atsushi escalated with each passing day, until she ended up in an insane relationship where her father went out and had sex in two seconds. Even though I know it's a dangerous act that everything will collapse if she finds out, I feel her pleasure and thrill in sex with Atsushi, who is stronger than her father, and I can't get out of it.
