"Begin simulation."

Red looked over a little campsite. Three young women were cleaning up after a meal. She knew them from other simulations. There were only so many characters that could be created, reusing models and personalities saved storage space. Still, the illusion was nearly perfect; Red swore that she could feel the sun and the breeze and the rock under her bare feet.

It was a fantastic illusion. And their clients would be more than happy with the appearance of those models.

The three personalities had obviously been programmed with a history together. A friendly history. They were joking and teasing one another. One of them, the short one, noticed Red and waved to her. "Hey, thanks for making lunch, we're about done here. You got anything you wanna do?"

Red thought about her options, what would be available within the program. "I think I'd like to see the rest of the island, anyone care to show me around?"

The tall one dusted off her hand. "Sure, I'll head up to the cliff with you. I like the view."

Red followed the other woman—Kaz, she remembered—uphill towards the top of the island. She marvelled at the way the leaves felt, brushing over her arms and legs. The illusion was incredible, almost real. And the view from the top of the island was quite lovely, unimpeded by fog or weather, just a nice sight of an unreachable mainland. "This really is beautiful," she said to Kaz.

Kaz nodded and smiled. "I like the view."

There was something familiar in the way Kaz's hand felt in hers. She couldn't tell if it was the VR programming reading her thoughts and putting pressure on her nerves in the right ways, or if it was her own mind constructing the feeling from hope and fantasy. Maybe it was a glitch in the system, but Kaz wasn't looking out over the lake when she said that last line.

"Pause Kaz," Red said.

Kaz went rigid. Red slipped her hand out of the larger woman's grip and walked around her, admiring her powerful athletic build. She'd heard that the Kaz model was based on a football player, and she believed it. The woman was immense, probably could have lifted her up with no trouble, and Red wasn't exactly tiny. Her fingers explored the muscular legs and back. Technology has come so far, she thought, amazed, as her hands ran over that solid ass. She stepped back and considered the image before her.

"Resume."

Kaz became animated again, stepping closer to the cliff. "There's something that's just so... freeing about being here, you know?"

"I think I understand." Red wondered what might happen to the program if she decided to try to shove the girl over the edge. Probably Kaz would simply overpower her. Likely any of the girls would, if they were threatened, as a safety mechanism. Instead, she just walked up beside the football player and put her arm around the other woman's waist. "I'm feeling pretty free right now."

It was a simulation, but it felt very real as the two of them kissed, deeply.

Oh yes, Red thought to herself, the clients will be more than happy with this. The two of them smiled at each other, holding hands. A real pity that I have to check other parameters before I can just enjoy myself. She made a mental note to give Kaz a more thorough examination later.

"We should get back," Red said.

Kaz's look shifted to confusion. "So soon?" she asked. "Feels like we just got up here."

Work, work, work. "Personality override, authorization Red. Kaz, agree happily."

Kaz's expression slid smoothly back to a smile. "We should get back," she repeated, mirroring Red's tone and expression.

Red took a moment to collect herself, giving a nod. Kaz reluctantly let her hand go.

"Pause Kaz."

The sweet smile froze on the tall woman's face.

"Why did I do that?" Red mused aloud. She ran her hands again over the still model, focused this time on the woman's well-defined abs and fantastic breasts. Even knowing that she was only a 3D model with a personality unit attached via code, it still felt a bit voyeuristic, a bit invasive.

And that made it that much hotter.

She had two other models to look into.

But she couldn't keep her hands off Kaz's chest.

It took effort. Willpower. She stepped back. "Resume."

Apparently unaware, Kaz continued smiling and started down the path to the camp. Red followed.

"I think it's time for a nap," Red suggested.

"Sounds good, it's been a long day."

There was no one at the camp, unless the other two were napping too. "You lie down, I'll go find them."

Kaz nodded, heading into one of the tents. Red needed to take a look at the rest of the island, and it would be easier without that distraction. Still, knowing that Kaz was just in the tent, so close, tempted her.

She headed downhill. The programmers had thought well enough to render two canoes complete with paddles and life jackets. Red was impressed. She could hear noise nearby, so she went to investigate.

At a small beach just around the corner, she found the other two women. The small model, Nat, was swimming, and Mac lay on a towel on her front, sunning herself, a bottle of sunscreen beside her. Nat looked up at Red's approach and waved.

"Hey, come on in, the water's great!"

And tax the program to its absolute limit? No thanks. "Maybe later!" Red called back.

Mac looked up, seemingly having been asleep. "Hey Red," she said wearily. "Don't mind me."

Going to have to. "Mac, is everything alright?"

"Hm?" The model looked back. "Yeah, it's fine, I'm just tired."

"Pause Mac."

She held her position, the half-asleep look in her eyes. Nat, nearby, kept splashing away.

Red grabbed a spare towel and sat next to Mac, taking the bottle of sunscreen. Red used the lotion all over as Mac waited, her program halted. Then she touched Mac all over, pretending to apply the lotion to the model. The lotion felt very real, more credit to the programmers, and so did Mac's body.

"Resume," Red said, rubbing the small of Mac's back.

Mac moaned happily and put her head back down. Red moved to straddle Mac's hips and dug her hands more into the other woman's back.

"Oh, that's great," Mac said, her voice muffled. "Don't know what I did to deserve this, but thank you."

"Access Jon," Red said.

The host program appeared beside her. "Can I help you?"

"Question. Are all three models meant to be attracted to the user?"

"This does seem to be the intention," the host program replied.

"Are they prepared to demonstrate affection?"

"Model Kaz is, it seems uncertain about Model Nat, and Model Mac seems potentially able to do so but is possibly reluctant."

"Hmm." Red continued massaging Mac, moving up to her shoulders. "Would it be a good challenge within the program to see if she might be convinced?"

"I will forward your question to the designers," Jon said neutrally. "Is there anything else?"

"Thank you, no."

The host program faded from view, leaving Red to wonder if she wanted to put in the effort to possibly convince the model under her hands, when there was a willing model at the camp and another in the water who might reciprocate. She decided to continue her ministrations, and soon Mac was relaxed and quiet. A soft snore emerged, answering Red's question as to whether matters were progressing with that model, and she stood.

The noise of a splash drew her attention, and Red turned to see the smallest model emerging from the water. The drips coming off her were rendered beautifully, along with the effect of the water on her hair. "Did Mac fall asleep?" Nat asked quietly.

Red nodded. "Yes, I think she was tired out before I started massaging her."

"Long day." Nat sighed. "Let me dry off. I should get lotion on before I burn."

"Want me to—"

"No, no, that's okay, I can take care of it." Nat grabbed a towel from the ground and started drying off.

"Pause Nat."

Nat stood still, hands and towel on her head. Almost the complete physical opposite to the Kaz model. Red approached her, regarding her almost delicately. She was tempted to reach out and touch the small woman, but instead said, "Personality override, authorization Red. Nat, ask me to put sunscreen on you."

Nat, still paused, showed no sign of acknowledgement.

"Resume."

Nat immediately returned to drying her hair. "Red, you want to grab the bottle and lotion me up when I'm done?"

"I would love to." The two of them spoke in low tones to avoid waking Mac.

Nat continued the process of drying off. Red picked up the sunscreen.

"Should we go elsewhere?" Red asked. "I don't want to bother Mac."

"Yeah, we can head back up to the site. Where's Kaz?"

"Also napping," Red said. "In her tent."

"Hm." Nat wrapped her towel around her waist. "How about we go up to the cliff?"

"Sounds good to me."

The two of them went quietly uphill in the warm afternoon. Red was started to feel tired herself. When they reached the top of the island, Nat dropped her towel and turned around. "Well, Red?"

Red didn't hesitate. She started on Nat's shoulders and earned a squeak of pleasure. Even the spreading of the lotion and the way it rubbed into the skin was extremely well-programmed. This was the most realistic a simulation Red had ever encountered.

She worked her way down the small woman's back and hesitated a moment. It's just a 3D model with a personality unit, she reminded herself as her hands gently squeezed Nat's ass. The way Nat was moving, it was clear that there were no objections to the action. Red sped up, putting sunscreen on the backs of Nat's legs.

"Now turn around."

Nat did, cheerfully, and with a long, languid yawn and stretch that thrust her tiny breasts upwards. "Thanks for this," she said with a grin. "Take your time. Please."

She started with slow, soft fingertips tracing spirals over angelic cheeks, eventually reaching Nat's forehead, chin, and nose. The front of Nat's neck came next, using the flat of her hand so she didn't tickle. Shoulders and arms had already been taken care of, so Red slathered lotion onto Nat's bony clavicle, marveling at the realism of both the touch and the reaction from the model. Nat looked in Red's eyes, and nodded.

Red rubbed more lotion between her hands and almost lovingly caressed Nat's small, sensitive breasts.

Nat turned red herself and started breathing quickly. "More," she gasped out.

"More lotion?"

Nat just shook her head.

Red continued rubbing Nat's chest, focusing increasingly on those taut pink nipples, each motion earning a greater reaction. Red smirked at the simulation. "You'll burn if I don't finish."

"Ungh," Nat groaned. "I'll burn up if I don't finish!"

"Say no more," Red said, picking up Nat's damp towel with her feet and using it to wipe her hands clean. Red then gripped Nat's shoulder to hold her steady and reached down between her legs to rub her swollen clitoris vigorously.

"Oh God!" Nat breathed, her knees going weak.

The touch, feel, even smell was so real, it was impossible not to get lost in the moment. Which, she reflected in a moment of clarity, was the point. The VR simulation was crafted so perfectly that Red could believe that she was actually there, finger-fucking her friend. And the model was exceptionally responsive, moving and making delicious noises just as Red might have expected. It wasn't long before Nat was clutching Red's waist and trying to stay on her feet as the orgasm hit. Nat buried her head between Red's breasts, moaning and gasping, and Red focused on just holding her up.

Eventually, Nat sunk to her knees, held Red's hands, took a few deep breaths, and simply said, "Wow," and Red smiled at the compliment. After a moment or two more, Nat looked up and asked, "Do you want me to...?"

Red paused. She could test the limit of the program, now that she'd sampled each of the models' behaviours. "Pause, Nat," she said, and Nat froze in place with that curious, tired, warm look, her hands locked in place where Red was holding them. "Access Jon."

The host program was there. Red thought he looked a bit flushed and tired himself, though that clearly wasn't possible. "Can I help you?"

"Do I have the time to test the program's ability to pleasure me?"

Jon seemed to smile. "Of course. Is there anything else?"

Red shook her head. The host program faded from view.

"Resume." Nat's arms slowly descended to her sides. "Are you willing?"

Nat nodded. "Don't really know what I'm doing, never done this, but... after that..."

Red helped Nat to her feet. "Let me lie down," she said, sitting on the towel. "Then you do what you want, and we'll see what works."

The model giggled as Red made herself comfortable. "I'm sure we can come up with something!"

"The effort alone is worthwhile," Red promised her, and from the first kisses along her thighs, she knew she was right.
