Cuckoos

Tito's lover, who is twice his age, becomes embarrasingly stuck to him in the most compromising of positions. Seeking assistant from a doctor Tito had thought was his father, he learns that his lover is actually his mother, his uncle Flavio is his father, and that the parachute Tito folded for Flavio's skydiving session didn't work, making Tito guilty of patricide. Sound familiar?
