It seems the walls were too thin, and the sounds from the next room were leaking through... Hearing that sound, the wife secretly becomes aroused. And the husband plans a swapping. They start exchanging wives and begin to sleep with each other's spouses. The couple cheats on each other across the thin wall of just a few centimeters. The sense of immorality transmits and increases the pleasure. In the end, they irresponsibly ejaculate heavily inside someone else's wife...
