In the West, bigamy is practiced by the Mormons, but this guy just lives with two girls at once and periodically has sex with both. So if today one sweetheart has a stiff back, and a friend is sure that the best remedy for this is violent sex, then the second one will definitely fall on a member in a home gangbang, because otherwise it will be treason. And if so, as it happens, then just group therapy.
