Girls in
Bird on a Wire (1990)

Wherever men of ideas and action gather to exchange theories and compare experiences, the talk invariably comes around to praising those few accomplished gentlemen among us who have wallowed in the physical delights of a mother and her daughter. The notion of gaining access to the most intimate, moistest recesses of two women, one of whom has squirmed from the womb of the other, is too much for a meek-willed male to contemplate without swooning. It's a hale and brave fellow who embraces the reality of copulating with two successive generations of directly descending females.
