JUX-449 - Secret Rendezvous: Wife's Hidden Past Comes Knocking

The film starts with a steamy marital sex scene after the protagonist reunites with a neighbor on moving day. The man stops Ichika after she sees her husband off in the morning. It turns out they had a past relationship, not the typical 'trained victim' trope, but compensated dating. The man lost his family and job because of it, but he's too soft to even blackmail her (-_-;). Later, as the plot suggests, she gets intimate while her husband is drunk nearby, and when he wakes up, she quickly covers it up. The next day, she visits the neighbor saying she 'can't forget the stimulation of sex with an older man,' but the act wasn't even that intense, leaving me wondering, 'Why is this so memorable?' The twist at the end made it click. It's a boring cuckold AV, but I'll give it 3 stars for the ending.
