An exciting way to improve a married couple in a rut: secretly using someone else's dick without telling the wife...
A solution to the couple's nightly activities that cannot be solved by the husband alone. It was a trick with an acquaintance to seduce his own wife. He summons his wife for a reason and records the whole thing as he cuckolds her on the spot. I thought that my wife would not like the advances of another man, but her underwear was wet and I confirmed again that my highly motivated wife was still interested in sex, and I was a satisfied husband (me).
