This is a room in a love hotel. A woman in mourning clothes appears in the room where the man is waiting in the afternoon. She rushed over after her husband's funeral. What is their relationship? And who is the man? Natsuo: "Oh, you're early." Yurika: "Because the road was surprisingly empty..." Natsuo: "You came in your mourning clothes? You should have changed." Yurika: "...I wanted to get out of that place as soon as possible." Natsuo: "You looked beautiful when you were crying just now. But it was fake crying, wasn't it?" Yurika: "...I just want to forget about it..." She hugs Natsuo. Her husband has died. They have no children and have been sexless for the past few years. This man is Natsuo, her husband's younger brother. I made a mistake with this man... Natsuo slowly removes her ring and speaks to Yurika. "You're a naughty sister-in-law. Do you really want me to punish you that badly?" He removes her mourning clothes to reveal her erotic underwear. He kneads her breasts and teases her nipples. He kisses her and licks all over her neck. He strips her underwear and starts tying her body with a red rope. He kneads and licks her breasts and teases her with his lips all over her body. Natsuo's cock penetrates her beautiful vagina that is no longer her husband's. Her moans echo through the hotel room. They sound more like cries of joy than sadness. Just as she climaxes, Natsuo's friend arrives. While Natsuo is in the bath, Yurika plans to play with fire. A trap for an encounter that enjoys a carnage. This slut Yurika deliberately sets traps to get herself excited, and then gets caught in the trap herself. She gets excited and enjoys getting the men excited. To ensure she gets pleasure from her overly intense sex.
