Unyielding Obsession

Jamie and her realtor went looking at houses, after Jamie had settled in at her new job.  They were just coming out of their last house when the rumble of a big engine coming down the street caught their attention. When the pickup truck that caused all the ruckus pulled in next door, the last thing she thought she'd see was a voluptuous woman climb out of the truck. 'Wow, that vehicle is quite a ride for such a hot lady'.
Was Jamie's first thought. The woman introduced herself as Sandra. Sandra was average height, about 5'5" with a better than average build. Not muscular, but athletically fit, and an attractive face. She was wearing a tight t-shirt and tight jeans.   And her ample breasts were pressed tightly to her t-shirt. And the jeans fit very snug around her hips. Over time Jamie would learn it was an outfit Sandra wore a lot.
She was the kind of woman that would give any lesbian wet dreams. Jamie bought the house. When Jamie learned Sandra was married, with two small kids and a handsome husband, she was undeterred. Like a patient hunter, Jamie decided to worship her from afar until her time came. So, for nearly a year Jamie had to settle for sneaking photos of Sandra in her tight clothes or listen at the window on summer evenings to Sandra and her husband making love.
But that was about to change, Sandra's husband was taking their kids to visit his parents for the weekend leaving her alone.
