moving inside for more pics

Sarah burst into giggles at Tom’s reaction, dropping the hem of her dress back down. “Oops!” she said with mock innocence, but her eyes sparkled with mischief. “I guess that wasn’t very natural after all.”

Tom stared at her, his camera still raised but no longer shooting. The image was burned into his mind—smooth, bare skin, perfectly groomed, the kind of intimate view that made his head spin with the implications.

“Sarah, what—why aren’t you—” he stammered.

“Wearing underwear?” she finished with a grin that was equal parts teenage rebellion and adult calculation. “I don’t know, I guess I forgot when I changed.” She shrugged as if it was the most natural thing in the world. “Besides, panty lines would totally ruin the photos, right?”

She was playing with him, Tom realized. The enhanced libido from his wish was making her bold, but there was definitely more of his adult wife’s knowledge guiding her actions than she was letting on.

“That was…” Tom tried to find words while his body reacted predictably to what he’d just seen.

“Hot?” Sarah suggested, tilting her head with that same sultry expression. “I mean, if you’re into that kind of thing. Which…” She glanced meaningfully down at his jeans where his arousal was becoming increasingly obvious. “It looks like you might be.”

The casual way she acknowledged his reaction sent another jolt through him. This was definitely not how an innocent teenage niece should be responding to accidentally flashing her uncle.

“We should probably go inside,” Tom said, his voice rougher than intended. “The neighbors…”

“The neighbors what?” Sarah asked, stepping closer. “Might see Uncle Tom getting turned on by his eighteen-year-old niece?” She was close enough now that he could smell her perfume, something sweet and youthful that made the whole situation feel even more forbidden.

“This is crazy,” Tom breathed, but he didn’t step away.

Sarah smiled up at him, her blue eyes holding both teenage mischief and adult desire. “You said to be natural. And naturally, when I’m around you, I get a little… excited.” She glanced down at herself, then back up at him. “Can you tell?”

The question hung between them, loaded with implication. Tom could see the flush in her cheeks, the way her breathing had quickened, the subtle signs of arousal that his wish had amplified beyond normal teenage hormones.

“Sarah…”

“Yes, Uncle Tom?” Her voice was breathless now, the playful teasing taking on a more serious edge.

Tom looked around, suddenly very aware that they were still outside where anyone could see them. But Sarah was looking at him with such open desire, such complete confidence in what she wanted, that his resolve was crumbling fast.

He took a deep breath and checked the camera. "I already have a few dozen shots out here. Maybe we should do a few inside," he suggested, hoping for a chance to calm down. His heart was still racing.

She nodded in agreement and they went back in. She plopped down on the sofa and crossed her legs, striking a silly pose with her arms and face.

"Sure, we can do some comic shots," Tom commented. He started snapping away. Sarah did a few expressions but the pics felt ****, the posing too artificial. "Just have some fun!" he advised.

She tossed her hair and smiled again. He snapped a shot. "Perfect!" he said just as she stuck out her tongue, messing up his shot. "Hah, I took that one anyway," he taunted.

She made a few more such expressions, letting him get a variety, then motioned him to sit down beside her. "That's enough don't ya think?" she asked.

Tom shrugged. "It never hurts to get more but we can stop for now if you're getting tired. I can always get some of you and Tonya together when she gets here." He sat down on the sofa, leaving space for at another person between them. This version of Sarah was beautiful and sexy, but spending the afternoon like this made him feel a bit strange. The more time he spent with her, the more he realized just how much she resembled his sister - almost like Sarah merged with Tonya, but younger. That, plus her behaving mostly like she was his niece, really threw him off.

Sarah sighed. "Not tired, just bored." She stretched her legs across his lap. He shifted on the couch, moving further away. She lifted one leg slightly, letting the hem of her dress ride up. His eyes darted down. She was barely covered, and he knew she wasn't wearing anything underneath. She slowly moved her other leg and foot across his lap, gently kneading his groin.

"Sarah..." he warned, the effects of her movements arousing him quickly. She obviously noticed his erection - she giggled again and purposefully began trying to massage it with her foot. "I don't think...." he started to say as he grabbed her foot to push it from his lap.

He paused with his hand on her, shocked again when she casually lifted her other leg over his head, resting that foot on the back of the couch. Now he had an unobstructed view of her neatly groomed pussy. "Wuh, what are you doing?" he stuttered. He knew she was his Sarah but the entire atmosphere of that afternoon and the newness of a wish-induced different life kept him off-kilter. "Your mom could show up.." he argued.

She smiled lasciviously. "Mom... did you ever fantasize about her when you two were young? Sneak peeks at her changing?" she teased, dropping her legs and sitting up. She slide onto his lap, the warmth of her naked groin making his penis twitch. She shifted directly over it so that he pressed hard against her. He could feel her increasing dampness through his pants.

She leaned in so that their faces almost touched. "Did you think about fucking her?" she whispered.
