Jack, 43-year-old pervert

Jack was bored.

His life was comfortable enough; he had a good steady office job, was married to a beautiful woman who came with two beautiful adult daughters, 19 and 21. He had a 20-year-old son of his own from a previous marriage who also lived in the house so it was fairly crowded whenever all five of them were home.

It was just all so boring. His wife, Melissa, had cooled to him in the few years since their marriage so it'd been a while since they'd had any sex. And it had been even longer since they had any good sex. She stayed busy with her own career, but since her only interests seemed to be working out and spending money, she was often out of the house. Jack figured there was a good chance she was having an affair.

His two step-daughters, Alicia and Gwen, were equally beautiful but completely different. Brunette and blonde, introverted nerd and popular cheerleader.
