Tim and Gwen swam after the chores were completed that Saturday. Much to her husband's pleasure, there was nothing but beautiful skin under the robe she walked up to the pool in, and he discarded his trunks as well. The couple happily splashed about for some time, their nakedness fueling their arousal until they made their way back down the house and their bedroom.
Much of the next day was spent at her parent's house for family dinner. Gwen kept looking for an opportunity to ask Alison exactly whether Jason had seen the contents of her boots, but the lack of privacy made that impossible. She spent the afternoon certain that her son-in-law was somehow looking at her differently, as if he saw her in a different light. The Slut dismissed the thought as paranoid but made a note to save the idea for fantasy material later. To both her distress and relief, her mother treated her as she always did, and true to her word, Natalie did her best to run interference and form a united front.
Gwen was in the office the next morning when she heard the sound of a vehicle crunching up their gravel driveway. The inventory report on the screen in front of her had her full attention, and she was late in moving away from the keyboard to investigate. The sound of a car door slamming, followed by a call of "Gwen, you up there?" echoed through the open garage bays below.
"I am!" she replied, her mood brightening at this unexpected visit from Natalie. There was the sound of quick steps on the rough wooden stairs, and her sister-in-law's head poked above the landing.
"Day off, out running errands," she explained as she finished her climb and hugged her sister-in-law. "Thought I'd take a chance and stop by." The two women compared notes on the previous day's gathering before Gwen suggested they walk over to the house where they could talk in more comfort.
"Thanks, but I've got a bunch of stuff to do today. I just wanted to drop this off for youโI think I know what you can get Tim for your anniversary." Natalie pushed a red leather-bound photo album into Gwen's hands.
"It's a nice idea, but we sat for a family portrait a couple of years ago," the tiny brunette replied. "Remember? The photo you have on that table in the study?"
"Yeah," Natalie replied slowly. "These aren't that kind of photo. Take a look."
Gwen flipped back the heavy cover to reveal the first shot. It was of Natalie, or rather, a reflection of Natalie as she looked into a carved-oak framed mirror. Her hair and makeup were perfectly done, accentuating the woman's face rather than changing it altogether. An unbuttoned white shirt covered her shoulders while a loosely-knotted red tie contrasted against the pale skin it lay upon.
"Oh, my." Even though there was nothing particularly lewd or obscene about this picture, it was obviously not intended for general viewing. She looked up at Natalie, who conspiratorially raised her eyebrows and glanced purposefully at the album, prompting Gwen to turn the page.
The next photo was still from behind her sister-in-law but now from a lower angle, the focus on the woman's back rather than her reflection. The shirt hung loosely, obscuring the curvaceous figure Gwen knew lay beneath, and ended just below where the curve of her butt began, the tail hanging off the firm globes like a short drape. Black high heels added a certain naughtiness. Gwen admired the shot for a moment before slowly turning the page.
It was of Natalie from the same angle, but her hands were now on the dresser before her, bending over ever so slightly as her reflection looked back over her shoulder. The shirt rode up accordingly, just enough to expose the lower separation of her cheeks, enough to hint at a lack of underwear without confirming it.
"I had these taken for Adam, for our anniversary, a couple of years ago," Natalie offered quietly, "it's a kind of photography called Boudoir." Gwen nodded but didn't look up, intent on the pictures she held in her hand. An urge to turn the page and see what was next fought with her desire to preserve her sister-in-law's modesty.
With an effort, she looked up. "These are absolutely beautiful, but why...?"
"I had these taken for our anniversary," Natalie repeated, "as a gift for Adam. I thought maybe Tim would like something like this from you?"
Gwen's eyes widened in understanding. "Oh, no, I couldn't do that," she demurred, pushing the open album back at the smiling woman before her. "You look incredible in these, but I could never look that good. I'd probably end up looking like a cheap prostitute or something. This just isn't something I could do."
"Does Tim like cheap prostitutes?" Natalie asked, smiling to show she meant no offense. "It's something you couldn't do before," Natalie corrected, pushing the album back. "It's something you can do now. C'mon, show your husband what a piece of ass you are. Cheap prostitute is a look I think you'd have a difficult time pulling off. Sexy as all hell wife and lover is one you'd be a natural for. Look, I got a bunch of errands to run yet, and I still have to pick up Tyler and get him to the dentist. Take a look at the photos and see what you think, then give me a call and we can start working out the details."
"I can't keep this! Won't Adam miss it?"
"I told him I was letting a friend of mine borrow it to see what a shoot might look like. I can pick it up once you've said yes." Natalie bent forward and kissed her on the cheek. "Gimme a call once you've had a chance to look through it and have some time to talk. Remember, this is going to be a gift for Tim, so not a word to him!"
Gwen snorted. As if she could tell her husband that she had been looking at sexy pictures of his sister-in-law! The blonde was hurrying down the stairs before Gwen could react. "But Natalie..." She stood there until her sister-in-law's car could no longer be heard. Numbly, she sat back down at her desk and again looked at the open album before her. Picking it up, she began to turn pages. Natalie moved and posed about an elegantly decorated bedroom, giving broad hints as to what lay beneath the white shirt without actually revealing it. Eventually the shirt was removed while the tie remained for a few shots more, and yet still the photos were taken in such a way to accentuate her feminine lines but not reveal the entire package, a peek of a nipple here, the tuft of pubic hair there, but still far less than what Gwen had seen in person. Mischievous grins alternated with sultry looks, her seductive qualities obvious. The last photo was of Natalie lying on the bed on her stomach, looking into the camera, the dusk of the tops of her areolae just visible above the white pillows that concealed the rest of her breasts, while the curve and separation of her buttocks were presented in softer focus behind her.
