Over Christmas most of the family had been staying with Kat's grandmother, but she had opted for the guest room at the nearby house of her Uncle Brian, J.J.'s father. At first she had regretted it.
Before this she hadn't spent much time around J.J.'s stepmother, Lauren, who had married Brian a little over a year before. Initially Kat was confused by the way Lauren acted towards her -- aloof, almost hostile. A few times she'd caught Lauren looking at her in a funny way, and when their eyes met, Lauren just stared straight through her, then after a few seconds abruptly looked away.
But on her second day there, Kat had dropped her phone on the floor and bent over to pick it up. Glancing over her shoulder, she saw Lauren staring at her ass, and realized: Oh, she's into me. That was why she was acting so weird -- she was trying to hide it. It all suddenly seemed so obvious, and Kat couldn't believe she hadn't figured it out before.
On the one hand, this was very flattering. Lauren was an extremely attractive woman -- a tall redhead with an athletic build, and gorgeously crystalline blue-green eyes. She was also a full decade younger than Brian -- a trophy wife, no doubt about it.
On the other hand, Kat wasn't sure she liked Lauren all that much. They were on very different wavelengths. Kat found Lauren to be full of herself, stuck-up, and materialistic. And she wasn't always very nice to J.J.
On the third hand Kat was horny. It had been a few days, and she had gotten used to a pretty steady diet of pussy. She found herself staring at Lauren's body -- which Lauren liked to show off with tight clothes and short skirts -- and salivating a little bit.
Then again Lauren was her uncle's wife. Kat had been with several married women in the last few months, but this was on a whole different level. In the end, she decided to take a wait-and-see attitude; she wouldn't make any kind of move, but just let things happen. Still, at times she found herself flirting with Lauren, almost against her will. She kind of enjoyed playing this game without feeling particularly invested in the outcome.
On that particular morning, J.J. and her father had risen early to join the rest of the family for a long hike. Kat, who liked to sleep in whenever possible, had passed on the hike, as had Lauren, who was not the outdoorsy type.
