It's a trap!

Rouge carefully opened the door of the safe, the anticipation was making her hands tremble. However, before she could get a decent look on the inside four mechanical arms shot out of the safe knocking her back.

"What the?!"

Taken off guard, Rouge quickly found herself ensnared by the arms as they took hold of her wrists and legs. Being held a few inches off the ground, Rouge struggled and strained to escape the mechanical grip of her captor.

"It worked!" Tails exclaimed ecstatically from the ground.

"W-what the hell is this?!" Rouge demanded, continuing to struggle against the mechanical arms.

Another mechanical arm slithered out from the safe and reached over to Tails. With just a few tugs it freed the fox from his bindings.

"I installed a security system just in case something like this happened," he explained, bringing himself to his feet, "and now that I've got you captured, I think it's only fair that I get some payback,"

"Oh please, even with some goofy robot arms you're not intimidating."

Tails cleared his throat, "Arms, remove Rouge's outfit!"

Several more mechanical arms popped out from the ground and reached towards Rouge. They began pulling and tearing away at her body suit until she was completely naked.

"What the fuck?!! Do you know how much those outfits cost?!"

She continued to struggle fruitlessly against the arms causing her breasts to bounce and shake wildly. Tails blushed, a bit self-satisfied but also a little turned on by her display.

"Don't get too upset just yet! Your punishment has only just begun! Arms, get Rogue into the presenting position!"

The mechanical arms clicked and beeped, and they began repositioning Rouge's arms behind her back, her feet above her head and her legs spread wide. She looked furious, like a cat dunked into a bath. If just one arm gave out Tails was sure she would kill him. Still, he approached her, allured by the opportunity presenting itself.

"So what now?" she asked in a rough tone, "Are you gonna try and fuck me with that tiny cock? How long will that last? Ten seconds? This is a joke," she rolled her eyes.

Tails smirked, waltzing over to his safe and he dug around inside before pulling out two unique objects. One was a Chaos Emerald, which Rouge recognized immediately, but the other took her a second. It was a harness, with black straps that wrapped around to a crotch piece, but what made this object interesting was the phallic object attached to the crotch. It was clearly a penis, a huge one at that, molded from a kind of silicon, colored red, and branded with the label 'Knuckles model V1' in bold white letters on the side. Rouge knew a strapon when she saw one and seeing a big one in the hands of Tails made her nervous.

"I always knew my size was a bit underwhelming, so I tried to remedy that," he explained, strapping the device onto his waist, "Say hello to a result of months of studying!" He then placed the chaos emerald on a slot at the base of the dildo and it began vibrating.

Rouge could feel the sweat beading up all along her boy as Tails approached her.

"N-now hold on a minute Tails, let's talk about this…"

Standing before her, Tails began aligning the tip of his dildo with the lips of her vagina. He pressed the tip onto her lips, which made her entire body tense up.

"H-hold on Tails! You can just let me go! I swear I won't come back!"

Tails smirked, "You wanted the Chaos emerald, right?"

Rouge didn't know how to respond.

"Well then take it!" he exclaimed, shoving the full length of the dildo inside her.

Rouge let out a massive moan. She couldn't control it, she could feel the vibration through her entire body. Tails pulled and thrust the dildo in a circular motion, each time prompting various gasps and moans from the captured bat.

"How does it feel?" he smirked.

She wanted to call him every insult she knew for humiliating her in this way. However, the pleasure coursing through her was too great and the only sounds she could muster were moans and howls. This only encouraged Tails to thrust harder and harder, until eventually Rouge was pushed to the point of the speech.

"I-I'm cumming!!!!" she exclaimed, biting her lip in delight.

Her body went stiff, as she let out a massive moan. Tails slowed his thrusting, and Rouge's body slowly relaxed. As he slid the dildo out of her, it was as if a weight had been taken off her shoulders. Her breathing was heavy and her heart was racing like crazy.

"Arms, escort Rouge outside, please," he directed, catching his breath.

In an instant, Rouge found herself being flung out of the workshop. Crashing to the ground, she seemed to come to her senses. She sat upwards in disbelief. He had completely flipped the script on her, not only leaving her without the emerald but without any clothes either.

"I guess that fox is a bit more clever than I gave him credit for," She chuckled, "Next time I'll need to account for the robot arms."

She flew off into the night, praying she could make it home before anyone saw her.

Tails was sat at his workbench vigorously masturbating. He was still in disbelief that any of that had actually happened and more so surprised that he had succeeded in protecting the emerald.

As a rope of cum shot from his penis, his body went limp.

He smiled to himself, "Next time... *huff*... maybe I'll let her interrogate me... *huff*...for just a little bit longer...."
