Four lustful mothers-in-law beg for their sons-in-law's bodies despite the guilt. One is left alone when her daughter goes shopping and craves more than a thrill; another offers to test whether an insecure son-in-law is really bad in bed; a third listens to his marital problems and lets "just a handjob" become full sex; the fourth notices his erection after he spills liquor on his crotch. Four hours of domestic affairs that cross every family boundary.
