Service with a smile...

Samantha had never before craved a shower more than this moment. Not only did she want the opportunity to clean away any dirt, sweat, or other fluids, not only did she feel an intense need to pleasure herself, but she had a need for feeling free. When the clothes were shed from her body, she felt surprisingly comfortable. It wasn't often she would seek self-gratification while wearing clothes, but something felt extra good about doing the act naked.

There was a naughty aspect to consider, masturbating in a public shower, but any thoughts about that quickly faded away. She was too consumed in the moment of pleasuring herself. The thoughts that did come to her mind, being naked, being outdoors, having Tiffany as her pet, and even being a pet herself, all swam back and forth, together and apart. She actually had to struggle a bit to choose one singular thing to focus on so she could keep up her antics.

But it wasn't hunky men or even curvy women that danced in her thoughts. Rather, she had an image of her, fully nude, and her sister, fully naked except for her collar, conducting this very act. Self pleasure, fingers in the owners' pussies, shifting back and forth. Fingers were caressing chests, nipples, stomachs, and of course, clits. "Wh...why?" Samantha tried to question herself.

The Tiffany she imagined didn't seem to notice, and Samantha only got more passion from that. "Why am I...?" Samantha was too embarrassed to finish that thought, and tried desperately to think of anything else. Samantha knew of so many fantasies, she had seen movies and stories, she had a pretty good imagination. The imagination was meant to shield her from the sight of her petgirl sister.

However, no other thought could hide away the image. "F-fine," Samantha said, giving in to her desires. "It's...it's just a fantasy...it's not real." But it felt very real to Samantha, and that was enough to get her to the edge. Her pace quickened, her fingers were slick, her nipples hard, and her back arched when a strong wave of pleasure coursed through her. And those strong waves kept coming...and coming...and coming.

"Yes...yes..." Samantha breathed. She was close, she needed just an extra push to get her over, and she could finally taste relief. Just a few more strokes, and she'd be there...

And then the door slammed open.

Samantha froze, terrified at the sound. But the surprises continued, as multiple robots rolled into the room, dropping off all of Samantha's orders in front of the various shower stalls they were ordered from. "Wh...what?"

One robot approached her and said, "We have come to deliver orders, as designated by our Relaxation And Ease Of Access Order System, Patent Pending. Can you explain where the other customers who made their orders have gone?"

There was a slow realization that dawned on Samantha, realizing that the robots were looking for a set of guests that did not exist. Rather than face the risk of trouble, Samantha hastily came up with a question to hopefully distract the robots. "Uh, why are you here already?"

The robot tilted its head in confusion. "Did you not read the special notes regarding deliveries?" Samantha shook her head, so the robot proceeded. "Among various assignments to be covered when orders are placed, we service robots are tasked to deliver products as soon as possible. With no distractions, it is why we could arrive within minutes."

This was all quite startling to Samantha, and she was given even less time to consider these words as the robot once again asked its question. Here she was, naked, wet, sitting in a very open and quite lewd position, and she hadn't even taken the time to pull her fingers free from her dripping hole. She knew she should have cowered back and covered herself, but the temptation wasn't as strong as the desire to keep herself filled.

The robot, now joined by another, squawked out the question, "Can you explain where the other customers who made their orders have gone?"

Samantha felt too nervous to answer. Even now, with more robots coming to pester her with the same question, she couldn't make a move. All she could do was slowly ease her fingers back and forth. In a weird way, the audience of electronic eyes almost made her feel confident.

It was an audience, and not one she'd have ever expected. She hadn't really wanted one before, she wasn't really comfortable with public displays, like her sister was at the airport. Though at this point, she'd happily consider her options if it meant getting to finally release her frustrations. She instead was just holding herself back, and she was gaining no pleasure from the self-restriction.

Finally, frustrated with holding herself back, and **** to get the robots away, she started to speak. "The other customers...they...left."

The robot assigned to her then responded with, "In that case, we must return the items until they return."

"No!" Samantha said, with a loudness that would typically fail the collar's restriction, had Samantha been wearing it. Samantha quickly recovered and said, "They told me...mmm, they told me...I should hold on to them."

Luckily, the robots were not very smart, and were able to easily believe the nude beauty. They soon filed out, and though Samantha paid some attention to their departure, her mind was already back on a much more important task.

As if the fingers had a mind of their own, they began to pump away into Samantha. She felt embarrassed, but this was probably the only place private enough for her. "With...Tiffany staying...in the same room...mmm...I need to be...out here...in public...where anyone could see."

Looking to the door of the bathroom, while it had closed after the robots filed out, it most definitely would not have locked. She was alone, but also open to be caught at any moment. She considered getting up to try and lock the door again, but she was too comfortable, and too busy working her pussy to the much-sought-after conclusion.

Samantha bit her lip, holding back a moan, and a swear. She would have privacy for the rest of her time here, but considering how pent up she was, a full audience of perverted persons would not cause her to stop. If anything, imagining the leering eyes made her want to push herself further. Any shyness Samantha had was soon forgotten. Whether it be Samantha's subconscious desire to express her nudity on a public level, or the antics of her sister awakening something within her, it didn't matter.

Was this an exhibitionist tendency coming to light? Was this the rumbling of a similarity to her sister? She wasn't a pet like her sister, but she was naked, outdoors, and intensely horny. She couldn't process all the emotions flowing through her, but they all flowed through the point of passion. With her fingers shuffling in a smooth but accelerating fashion inside her pussy, with her clit getting the touches and swirls to give the occasional jolts of life, her mind soon focused on the one emotion that mattered to her most in that moment.

"Mmm...please, please...I'm so close...please..." Her mind was fighting against any feelings that could distract her. All she wanted to think about now was her own needs, her own **** desires, her ever-growing and unstoppable passion. That feeling...that ruled her mind, commanded her to continue without worry, to let her fingers build more friction in her body and make her pussy and clit feel like they were being graced by a godly touch. Her imaginations and fantasies that let her cum so many times before was soon overcome by a single, intense, driving feeling.

Passion. Pure desire. Need for release increasing and accelerating and causing pulsing and jolts of delight surging all through her body. The heat swelling through her body was defying the cold water pouring on her. The mind once filled with thoughts of worry and indecision were clearing away a cloud of confusion. Her thoughts focused, her fingers pumping, her breathing going faster and faster, her moans getting louder and louder, her back arching further and further, getting as much as she could as she pushed herself closer to the edge, closer, and closer, and closer again until at last...

"Please please please pleasssssse....yes! Yeeeesssssss...fuck yes!"

At long last, Samantha finally came. And a well earned release it was. After being left hanging for days, with pent up frustrations at a height never felt before, Samantha could finally feel relief. "Heh...I swore," she said between breaths. After such a long wait, she couldn't help herself to a expletive, and a fitting one at that.

She laid on the floor of the shower for several minutes. Truthfully, she would have laid their for several more hours, but even in a mindset of utter peace, responsibility came back into her mind. Slowly she remembered she had to check on Tiffany, and bring the supplies back. As Samantha lay naked and still thrumming with delight, she wondered aloud about Tiffany.

"She wouldn't mind if I was late...she's probably exploring some of her own passions." Samantha then laughed, and closed her eyes to focus on breathing. "No...maybe not."

She paused again, thinking slowly, regaining her strength. "Then again, Tiffany's been so strange on this trip. Maybe this is just her becoming who she wants to be." Samantha raised her hand above her face, still slick with juices. "I need to figure out who I want to be."

That would be a thought to explore at another time. For now, Samantha needed to check on Tiffany. She hoped it wouldn't be too awkward of a reunion, but that thought was replaced by another. It was getting late, and she suddenly realized that she really didn't want to put clothes back on.

"I shouldn't...though then again...I did want to explore myself...and my desires, even more..."
