I remember seeing Scorned on late night cable tv in the 90's. So many good softcore erotic films and series were made in that decade, just like The Other Woman.
Seeing her mother making love with another woman no doubt piqued her interest, but genetics did play a part in her partaking in lesbian lovemaking herself later in life. Notice how the morning after the sex she says she felt no guilt or shame and was 'reborn', as if a repressed part of her true self was finally freed.
Jessica inherited her lesbianism from her mother. Both lesbian scenes are extremely sensual and stimulating. with the sex between Jessica and Traci being one of the best erotically filmed scenes I masturbated and shot my load to countless times since it was released in 1992..
