Raped in front of my husband's eyes - Midsummer seduction

Miki is a married woman who has been married for five years and lives happily with her husband. One day, Yohei, a former colleague at a convenience store where Miki once worked as a part-time worker, came to visit. He found a necklace that Miki lost while he was working, so he brought it with him. Even after Miki left work, Yohei, who had been feeling even more affectionate, has a chance to see him.
