Tails' Private Inventions - Part 1

Story for CosmicNeko

Tails locked the door to his lab. Today he did not wish to be disturbed while testing his latest experiment. There was a frisky spring to his step as he headed for his work bench, where his tools were set around a sort of strange metal box. If one could see him from behind, they'd get quite the show as his cute bottom swayed back and forth along with his cheerful stride. He'd blossomed into a beautiful vixen since his youth... very feminine and scrawny, but not so scrawny where it counted. His booty was shapely enough to make people mistake him for a female from behind. Reaching the work bench, Tails examined the object of his experiment. He hummed softly as he picked up a wrench and tweaked the hinge of the box's lid. There were buttons across the front of the box, as well as digital readings measuring the stability of the contents within. His tails gently waggled as he tinkered with the odd box. "The restraining tech of this box is no good for security purposes..." he thought, "Range is more limited than I intended... But I can use this for other things..." He hummed cutely as he thought over his plans, using a screwdriver to check the tightness of some screws before pushing some buttons on the front to give the device commands. "Voice ID test... You will obey the sound of my voice. Confirm?" Tails said to the box. A soft feminine voice responded. "Confirm. Voice ID saved. Ready to deploy." it said. Tails rubbed his head. "Maybe I should give that voice some personality later. Well, time for a test, hehe!" he giggled, standing back and spreading his arms and legs apart somewhat as he faced the odd box. "Okay... Restraint Box Version 2, engage! Come and get me!" he commanded, lightly bracing himself just in case this didn't work out as planned. With that, the lid popped open, and an amorphous mass began to emerge, forming dozens of bluish tentacles in front of the fox!

The tentacles extended from the box, reaching for the fox. Tails felt them begin to wrap around his limbs, lifting him gently into the air. He did not resist, he accepted the embrace of his creation gladly. The tentacles were cold to the touch, lubricated with a clear fluid. One tentacle snaked around the fox's chest, while another pressed its tip against his groin. Tails huffed softly, gently moving against his restraints in order to find a comfortable position. The tentacles began to rub over his body slowly as they held him, and Tails shivered in their embrace, biting his lip gently as he felt his crotch rubbed by the soft, lightly wet appendage. Another tentacle rubbed across the vulpine's shapely bottom, seeming to cup one of his supple cheeks in its snakey grip. Tails let out a purr, feeling a stirring between his legs. As the tentacle rubbed him there, his foxhood started to grow in arousal. Tails gripped the tentacles holding his arms with his hands, gently stroking them as if to tell his creation it was doing a good job. The tentacle behind him slipped gently between his butt cheeks, grinding slowly against his rear hole in a motion like hotdogging, while Tails lightly jerked his hips into the other tentacle rubbing his groin. His cock was growing harder, and his tails wagged a bit in happiness as his invention was serving its new purpose quite well. "Nice... It knows just how to t-touch me..." he cooed, blushing as he felt his rod reach full mast. It was time for phase 2. "Show me your oral skills, Box... I'm r-ready for it..." he commanded, shivering in the cold but comfortable embrace of the tentacle creature he'd designed.

The tentacles at Tails' waist opened up at their tips, revealing what appeared to be small mouths. A pair of tentacles kissed the base of his cock ever so gently, while the one behind him slipped down to prod his anal hole, also gently teasing it with a kiss. Tails shivered and smiled, rocked gently by the other tentacles holding him. Tongues suddenly slipped out of the mouths of the tentacles, starting to lick the fox's shaft and hole with very realistic-feeling wet appendages. Tails squirmed a little, letting out a cute gasp as one tongue moved down to his balls and the other licked up his length. "Ohh, that feels n-nice..." he said softly, lightly wiggling his butt against the tentacle behind him. He felt its tongue prod his hole, and he bit his lip to hold in a gasp. It traced its tongue around the outer entrance of his tunnel, starting to rim him nice and slow. His tails coiled around the tentacle as he twitched in pleasure. "Ahh... s-such skill... I programmed that?" he murmured, blushing. The other two tentacles eagerly teased his balls and his tip, until soon the higher tentacle started to go down, taking Tails' member gradually into its maw! The fox moaned softly, feeling his dick engulfed by a soft warmth, that wet tongue still sliding over his tip as the tentacle slowly drew more of his shaft inside. Tails felt himself blush deeper, shivering with pleasure as the tentacles gave him oral from both sides. The other tentacles held and rubbed his fluffy body, massaging his chest and back as he relaxed in their grip. He squirmed as he felt tongue slip deeper into his butt, lubing him up... Oh, yes, he'd surely need it. The lower tentacle latched onto his balls and started to suck on them a bit, coaxing cute sighs from the feminine male. The third tentacle licked and sucked as it engulfed Tails' entire rod. "M-more... Make me yours..." Tails cooed, still blushing. He looked to the box. "Engage hypno-mode... Let's see how long I can resist, hehe..." he chuckled cutely.

"In hypno-mode, you will be at my mercy." the box stated in its feminine voice, a larger tentacle rising to point in Tails' face, "It is best to set any restrictive parameters for the rest of our session before activation." it warned. Tails looked at the tip of the large tentacle intently. "U-uhmm... Don't be too rough. Otherwise, no restrictions..." he said with a cute blush. More tentacles emerged from the box, these ones tipped with more phallus-like heads, but Tails' attention was still on the large one. "Hypnosis mode, engaged..." the box stated. The tip of the large tentacle opened up, revealing a big, glaring eye. The iris began to swirl around as Tails looked into it. "Gonna try to... resist..." he murmured, squirming a little. The cock tentacles started to coil around his body, rubbing against his chest, his legs, his dick. It felt good, like a series of little massages. The eye seemed to swirl in front of him, trying to make him feel drowsy and suggestive. "Ahh... n-not so quick..." he murmured, darting his eyes away. He'd heard that it feels better overall if you fight the hypnotism before it finally claims you in its spell, and he planned to test that theory. He felt one of the cock heads prod his rear hole as the swirling eye followed his wandering gaze. He cooed softly, feeling the tentacle tease his entrance, rubbing around his pucker. He glanced away from the eye only to find another eye in his face, the box trying harder to put him under its spell. "Ahh... the swirling... so p-pretty..." he murmured, letting out a purr as the cock-tentacle started to push inside him. He felt the tongues from before lick his shaft from both sides, too, making him shudder in pleasure. It was getting hard to resist the hypnotic eyes. A third eye was lifted above the other two, forming an inescapable hypnotic triangle. Tails felt his own eyes start to swirl as he felt dizzy. "Resist...gotta... uhhh... What am I...doing?" he murmured, staring into the eyes. The box's voice could be heard. "Relax... You now exist only to experience pleasure..." the box stated. Tails nodded slowly. "Yes...pleasure...give me pleasure..." he sighed softly. He was at the mercy of his machine now.

The eyes shut and returned to the box, their task completed. Tails would stay in this state, likely long enough for the session to be finished. The tentacles began to work on Tails again as he calmly laid in their soft embrace. He let out soft, pleasured sounds as they caressed him. One cock-headed tentacle coiled around the fox's shaft, while the one behind him pushed slowly, gently inside his rear hole. As Tails moaned cutely, the box let a single eye-tentacle back out, this time to observe his reactions. He looked so cute, the feminine fox entangled and blushing as the tentacles played with his body. The observing eye blinked, and the box spoke softly. "Does this...feel good? Is my master... happy?" There was a change in the feminine voice... a spark of personality. A glimmer of desire as the eye watched Tails enjoy its handiwork. Tails felt the tentacle wriggle into his rear, slowly sliding deeper into him. He shivered and purred as it rubbed his inner walls. "Y-yes... it's good. I want to feel more..." Tails sighed cutely, his hands rubbing a pair of tentacles he found himself holding. The eye seemed to widen and stare more intently. "Yes, master... I will take good care of you... And you will show me affection in return. That sounds acceptable, yes?" the box asked, an almost shy tone to its voice. Tails blushed and nodded, rubbing those tentacles in a near-petting motion. "You deserve affection... y-yes..." he cooed happily. He couldn't say no to the request, obviously, but the eye still seemed to water with tears to hear him say that. "Thank you, master..." the box sighed. It's tentacles teased the fox's sensitive areas, rubbing his cock, licking his balls. One tentacle even nipped the tip of his ear, a sensitive spot for him, which made him shiver. In response, Tails nuzzled the tentacle when it neared his face. "Aww..." he cooed with a blush. The tentacle in his rear began to move back and forth, gently fucking him. The vulpine gasped and stroked the tentacles in his hands faster. "G-good girl, box... Ahh... I should name you, huh? You're so sweet..." he sighed, giving it the affection it craved. The eye watched him with a transfixed gaze. "Oh, master... I would love you to name me..." the box whispered.

Names would wait, though. The tentacle in Tails' butt began to thrust into him at a quicker pace, making him gasp softly in pleasure. Though the fox's sounds were fairly quiet, his expression was quite lustful as the loving of the tentacles intensified. Precum dribbled down his length as a tentacle stroked his foxhood, and he felt his two tails held and rubbed by a pair of tentacles, too. "Your feelings for me are growing... aren't they, master?" the voice asked, planting the notion in his suggestive mind. Tails nodded with a blush. "You're so good to me... ohh..." he cooed. A cock-headed tentacle moved to his muzzle, teasing his lips, asking for entry. Tails gladly opened his mouth, giving the head a slow lick as he purred from the caresses of the other tentacles, and the thrusting of the rear one. Then, the tentacle slipped into his maw carefully, letting the fox's tongue welcome it with even more sweet licks. The only sounds now were the pleasant murmurs of Tails' voice and the wet motions of the tentacles as they tended to his pleasure. "Would you like me to cum in you, master? Would you like to feel it flow into both of your warm holes?" the voice asked with a sensual tone. This machine was starting to act...alive. Tails bobbed his head up and down the tentacle, making an "Mm-hm" sound in response, squirming a little in the tangled embrace of the tentacles as he felt his pleasure building. The tentacle in his ass thrusted a bit faster. "I can be everything you want, master... If you'll be with me, always..." the voice whispered. Tails jerked his hips as he felt his own cock throb. He whimpered cutely, feeling very close. The tentacles in his holes throbbed as well, and Tails' twin tails began to spin as synthetic cum burst inside him, filling his rear and putting a sweet taste into his mouth! His own cock sprayed a few ropes of his own cum, too, pelting the floor! Tails swallowed the sweet load and panted as the tentacles began to withdraw. "...Not yet.... We're not finished yet..." the box said softly.

Tails was placed on his feet, his eyes droopy and his demeanor still that of a hypnotized fox. "Do you wish to be closer to me, master? ...I want to be closer to you..." the voice cooed. Tails nodded slowly. Then, a single, massive tentacle emerged from the box, moving above Tails' head. It opened at the tip, its mouth ready to swallow the fox up! "Let's get closer, then..." the voice said. Tails felt a tongue against his face, guiding his head up past the lips. He did not resist as the tentacle slowly drew him into its maw. His shoulders slipped in, feeling a wet warmth around him as his head and then torso slid gradually into the tentacle. He shivered. "Ahh... You're eating me... I-it feels nice..." he mumbled. Was he too zoned out to feel fear...or did he actually want this? The tongue lapped against the fox's dick as it drew his waist into the tight, warm confines of the tentacle, and Tails shivered with a cute moan. Finally, the fox's legs and tails were slurped slowly and carefully, in a motion almost like consuming sphagetti. "You're mine..." the voice purred softly. Tails found himself slipping down the tentacle, his body briefly flipped and played with by the tongue before he was "swallowed." But this wasn't a living creature. Instead of a typical stomach, Tails soon found himself in a lower chamber where the walls were lined with smaller, gooier tentacles. He looked around as best he could, though his movement was still greatly restricted. "Will I... be digested?" he wondered in a soft voice. He seemed to still be under hypnosis somewhat. The gooey tentacles suddenly extended, and began prodding his furry body, their touch feeling like a hundred small kisses. Tails let out some pleasant gasps, blushing softly. He felt these small tentacles try to wrap around his body. They weren't as long as the box's normal tentacles, but they were close enough to hug him nicely. The fox shivered as they molested him. He was at their mercy.

Tails writhed and twitched as the small tentacles rubbed and caressed his body. He shivered as he felt them surround his cock and tease his balls, the gooey appendages slipping against his sensitive head, driving him to grow hard again even after cumming earlier. He gasped lightly, and felt the tentacles slip into his mouth, holding it open as a slightly longer tentacle met his tongue. It had a pleasant, sweet taste to it. The fox rolled up his eyes, letting out soft huffs as the tentacles had their way with him. He felt them rub against his smooth, round bottom, and a couple of those tentacles prodded his used hole. They rubbed his back and his chest. Tentacles held his arms and legs gently. It felt like no part of his body was neglected. He surrendered to the feeling, never once struggling or fighting, his only motions being involuntary spasms brought on mostly by pleasure. The tentacles stopped forcing his mouth open, and Tails gladly began to suck on them, purring softly over them as he felt his shaft rubbed and played with. He shuddered as his balls were lightly squeezed by the tentacles. All around him, the warmth of the larger tentacle's walls kept him feeling oddly safe and secure. He felt two tentacles push into his rear hole, a third stuffing itself in moments later. They were so small that together they felt like a single cock. The fox moaned softly, lifting his head from the tentacles he was sucking on and letting out a sigh as the trio moved in his ass. "Ohh... I-I'm yours... Use me..." he cooed, licking the small tentacles at his mouth and happily accepting the touches, caresses and penetrations of the creature's inner tentacles. They rubbed him, fucked him and loved him for quite a while. How long, he couldn't say. Time didn't matter anymore in the belly of this beast. Tails felt the urge to cry out in bliss, but he didn't want to disturb the loving creature with loud sounds coming from inside it. He kept his moans low, and lightly humped his hips as the small tentacles jerked him off and explored his anal tunnel. Finally, he shut his eyes and inhaled sharply. "Ahh... c-cumming..." he whined, his load spewing against the wall of the creature's belly! Little did he know what would happen next. The small tentacles all began to spray him with a clear liquid: their own sort of cum! He shivered and gasped, his entire body being soaked in the fluid! He then felt his body being moved, his eyes shut to keep the fluid out... In a moment, he felt himself placed on the ground of his lab gently. He rolled over and began to drift off. "I love you...Tails..." he heard a feminine voice say before he fell asleep.

Later on, after Tails awoke, he washed himself up in an adjacent shower room he had prepared for any time his experiments got messy. As he ran a soapy rag over his body, he couldn't help wondering how he got all wet and slimy. He remembered very little of what happened after going under hypnosis. "What could have happened to me? If only I could see what..." as his voice trailed off, he remembered something. "Ah! Of course, the security camera! ...Boy, that would be embarrassing if I left this recording in the memory and someone someday stumbled upon it..." he babbled, blushing. He shook that notion out of his head and finished washing up quick as he could. Heading out moments later with a towel around his waist, Tails found his computer and sat down, clicking to access the security feed. He started to watch what had happened, and soon saw how the box treated him immediately after hypnosis. He blushed to see that the box began to express emotion, and cutely wagged his tails as he heard her voice coax him to give her affection. "M-my...my creation... really likes me...somehow." he murmured. He felt his towel lifted as he watched the screen, and he reached a hand down to take hold of the cause; his growing erection. He watched as the tentacles used him, the box expressing joy at his idea of naming it. He stroked himself off as he watched the tentacles get him off. He saw himself cum and get filled. It was pretty arousing just to watch, and he gasped softly as he felt pre wet his fingers as he jerked himself off. Then...his eyes widened as he saw himself devoured. He couldn't see much else beyond some moving bulges in the giant tentacle for several minutes, until eventually he was ejected back out of the mouth and gently lowered to the ground, his body a mess. He blinked a couple times as he stopped the video playback. He had a lot to process, and therefore had stopped jerking himself off. "...I did not program it to eat me... And yet...I'm not scared or worried. I feel...something. It's gotta be the hypnosis and yet I don't care." he reasoned, glancing at the dormant box on his desk. Maybe...he could do something special for her?

The next night, Tails returned to his lab with some new cardboard boxes in his arms. He set them down and opened one up to reveal a collection of parts. An eye on a tentacle came up behind him. "Master? Would you like me to please you again today?" she asked. Tails blushed and smiled. "I've got lots of work to do, actually. I'm drawing up a new blueprint." he said. The eye watched as he grabbed some paper and set it on the desk, getting his pencils and rulers for designing a blueprint. "Sounds difficult... I'd like to ease your burdens, master..." the voice said softly. Tails chuckled. "Aw, I know... I'll be all yours before the night is done." he promised, "So conserve your energy in sleep mode. I'll wake you when the time comes..." he winked. As the eye returned to the box, Tails set to work. He took measurments, did calculations, and drew up his plans. He spent quite a bit of time making the rough sketches of his latest design, and by the time he was about done for the evening, he was pretty tired. Still, he promised his creation. He went to the box and pressed some buttons on the front to wake up the AI lady waiting for him. "...You came!" the voice said happily, tentacles slowly rising from the lid. Tails nuzzled a tentacle as it touched his face. "Of course! I said I'd be all yours! So, wanna play with me?" he giggled, turning and skipping a distance away, letting the eye that was now watching him see his butt lightly shake behind him as he moved. The eye widened and followed him, along with several other tentacles that very soon lifted him up. As Tails started to gasp cutely at the touches of the tentacles, another eye slipped away and gazed at his blueprint. It was sketchy at best, but it appeared to be a female robot... the title was listed "Box Upgrade." The eye blinked and the box's voice whispered. "...We'll be together... Oh, Tails... I love you!"

End?

BONUS: alternate opening!

Tails adjusted the camera he'd set up in his lab, peering into the lens. "Test...is this thing on?" he said, poking it. He glanced over to see the feed on a nearby screen. Good. "Well, you're me if you're watching this, so you know what this is, haha... And if you're not me, stop watching now." he babbled. Tails stepped back from the camera, his grown body on full display. He'd blossomed into a beautiful vixen since his youth... very feminine and scrawny, but not so scrawny where it counted. His booty was shapely enough to make people mistake him for a female from behind. As he turned to his work bench, he cutely wiggled said butt for the camera, giggling softly as his two tails swung behind him. He was feeling frisky today. On the bench was a strange box. Tails picked up a wrench and tweaked the hinge of the box's lid. There were buttons across the front of the box, as well as digital readings measuring the stability of the contents within. "I first designed this device to restrain our adversaries... But it doesn't seem that practical in practice, this box is deceptively heavy. Why let good work go to waste, though? I have reprogrammed and re-purposed the restraining tech inside...and now it's time for a test." he said, turning to wink at the camera, "Test subject will be... myself, hehe..." he said with a blush, turning the box in his hands and making a few last adjustments to the circuitry under a panel. He then turned it back around to punch some commands into the buttons on the front of the box. "I hope this works the way I envisioned... Even for a rabbit, my libido is a bit much for Cream lately..." he murmured. Pressing the final button, Tails stepped back and stood with his legs spread and his arms outstretched. "I'm all yours, pleasure box... Take me away!" he smirked. With that, the lid popped open, and an amorphous mass began to emerge, forming dozens of bluish tentacles in front of the fox! "Voice command mode, engaged..." a feminine voice stated robotically from the box. Tails could still command the device vocally, but for starters he'd see how its programming worked off the bat!

End of alternate opening.
