SDAM-016 Married couple exchange! One thin cover! Suspicious of the obscene sound heard from the neighbor! Fire lit W affair

Two couples called in the project “Please tell me the secret of good friendship”. During the discussion, I heard an obscene kissing sound from the next room (the sound that the staff played with a radio cassette player to make me feel H and suspicious). Each room gradually estrus while becoming suspicious of the sound, swapping across a wall.
