Under a Long Siege

The Earth, suffering under the relentless attack of invading aliens, the humans still tried to live some semblance normality. Natalie, a young woman at the onset of the invasion was involved in a relationship with a State Trooper, Andi. Andi was protective of Natalie while they were involved, the two were together when the invasion started. Despite their need for normalcy, the psychological effects on Natalie were more severe than Andi's.
Though their love burned brightly, Natalie couldn't help herself from being unfaithful to her lesbian lover and sought out other women to satisfy her craving for intimacy. Eventually Andi, with her patience wearing thin, broke of their relationship. At the time it seemed to have no effect on Natalie. It just seemed to open the flood gates to her lust. A young and beautiful Natalie was in demand in mature lesbian circles, and she basked in the attention lavished upon her.
For years the alien invasion wore on, the clock didn't stop, and Natalie was now middle aged and found, she was not in demand, rather she had turned into one of those mature lecherous women that cruised for young girls. The realization of her situation caused Natalie to adapt her pursuit of pleasure. She unexpectedly runs into her former lover Andi while she was cruising a popular lesbian hang out.
Their run in was as ugly as it gets and as she leaves the vengeful Andi, Natalie is caught in the web of an alien press gang and herded aboard an alien transport craft never to see Earth again.
