It's been five years since they got married, and although the couple's relationship hasn't cooled down, the night life seems to be stagnant, Mr. and Mrs. Suzumiya. The husband tries to break the rut with cosplay etc., but his wife Mari is in agony. Shinji, a brother-in-law who visits from time to time, sees through that and is overwhelmed at the moment. The frustrated body of Mari, who secretly expected to be violated by the strong body of Shinji, suddenly leaked a pant voice while resisting.
