As the days on Mobius grew colder and more frigid, Tails remained in his lab working on his inventions to keep himself occupied. "Can't wait until Cosmo sees my latest invention, it's bound to provide her with the needed heat and sunlight she needs to enjoy this winter", he remarked to himself as he worked on the large orb shaped machine. At once, Shadow the hedgehog entered his lab. "SHADOW", Tails exclaimed in surprise as he drew a tarp over his invention, "What are you doing here?" "I wanted to see if you could work on my hoverboots", Shadow said with his typical stern tone. "I told you, Shadow, it's too advanced for me to work on", Tails scoffed at him, "Besides you're fast enough as it is". Shadow glared at him angrily but Tails tried to ignore him. "And you can stop giving me the evil eye", Tails said without looking back at Shadow. Shadow grew further irritated by this then looked over at the tarp covered machine, "What's this you're working on?" "Oh it's a fusion simulator", Tails said excited that he was taking interest in his invention, "It produces a small simulation of the solar sun providing warmth and light but at a safe enough size to avoid rising temperatures or gravitational pull". "Apperantly you never saw SPiderman 2", Shadow scoffed at the young vulpine, "besides you're neglecting the magnetic solar flares that they frequently expel". "I know I'm working on that", Tails sighed as he pulled the tarp off and resumed working on his invention. "What's this for really", Shadow interrogated the fox, "The humans don't need it and I doubt you possess the capability to use this to power a city". "I know, it's just for experimentation", Tails exclaimed back. Shadow glared directly at the anxious fox, "It's for Cosmo, isn't it?" Tails blushed heavily but yelled, "Of course not!" Shadow smirked evilly, "Yeah right, I bet you did this as a christmas gift for Cosmo. Then maybe get a more interesting gift from her". Tails' blush darkened, "W-W-What do you mean?" Shadow shook his head knowing that Tails was about 13 by this point as was Cosmo, "You're old enough to know the 'facts of life'. You want to see Cosmo smile at your gift then probably slip off that green dress she wears". Tails blushed even more then felt something he never felt before. He looked down and saw a strange protrusion from his groin but knew what it was. He tried hiding it with one of his tails but Shadow could tell what was going on.

"What are you hiding, fox", Shadow smirked evilly approaching the shy vulpine. "N-N-Nothing! It's nothing" Tails yelled trying to hide himself. Shadow sprinted behind him, grabbed hold of his arms with one hand then pushed one of his tails away to see Tails' "embarrassing situation". "Oho, seems the young fox has an erection", Shadow smirked. Tails angrilly spun his tail like a propellor knocking him away, "Get away from me!" Tails flew up to the top of his lab but was instantly knocked down by Shadow's hover attack. The fox then fell but was grabbed by the ultimate lifeform and pulled towards a metal table with leather straps. Tossing Tails onto the table, Shadow used his speed to strap Tails to the table with the vulpine's member still erect. "Now just relax", Shadow said sadistically as he pulled off his gloves, "you'll enjoy ths". "Enjoy what?", Tails said fearfully, "What are you going to do? Don't hurt me!" Shadow's right hand grasped hold of the vulpine's member giving it a little squeeze. Tails gasped and slightly moaned as a feeling surged through his body like lightning. "I told you you'd enjoy this but for now let's take this nice and slow." Shadow warped away momentarily then reappeared with several white feathers. Smirking evilly he picked up one of the feathers and stroked it very slowly up and down the shaft of Tails' member. "Aaaaaahhhh, stop.... aaaaaaaaaa", Tails moaned some more as he felt his member being slowly stroked by the fluffy ends of the feather; up and down the shaft to circling around the very tip. Shadow enjoyed this as well since he liked to use his own brand of torture on the naive young vulpine but with him coming of age, Shadow decided to try more fun techniques. "Ticklish isn't it?", Shadow smirked but then tossed the feather aside and grabbed hold of Tails' left tail, "But let's see how much you like tickling yurself". With that, Shadow used the ends of Tails' left tail to stroke the vulpine's growing member. The young fox kept moaning but didn't want this to stop for some strange reason. Whatever Shadow was doing, it felt unbelievably good.

After ten minutes had passed, Shadow let go of the fox's tail then clutched the fox's member in his right hand and began slowly stroking it up and down. By now, every sense, strength and vision from Tails' mind had vanished in the wake of this surge of ecstasy he felt. He could barely breathe feeling Shadow's bare hand caressing his member. "Aaaaahhh oooooooo mmmmmmmmm yeeesssss", Tails moaned as he clenched his fists. Suddenly, Shadow saw something he never expected. Another grew. Shadow smirked devilishly and licked his lips, "I guess it's not just two tails that you've got, fox boy". Curling his remaining hand around Tails' second member, Shadow began stroking them at a slow and agonizing speed. Tails' moans grew wild from this turn of events but this didn't change the state of pleasure he was undergoing. As this continued, Shadow would toy with the fox by either temporarily increasing the speed of his stroking one of Tail's members before slowing down again, tickling both of the sensitive tips of the fox's members with his thumbs or sneaking in quick licks and nibbles along the tips. Either one had Tails continously moaning and begging for more. After over ten minutes of this he felt that every ounce of pleasure coursing through every point of his body. As Shadow continued stroking, he saw both Tails' members leak a little pre-cum compelling the ultimate lifeform to slow down. "No.... Shadow... don't stop", Tails begged. "You want me to continue", Shadow smirked as he began slowing down his stroking of the young vulpine's twin cocks to a near stop. "Yes... please", Tails begged. Shadow smirked evilly again as he continued squeezing Tails' members, "Alright". Instantly, Shadow began stroking Tails' twin cocks with both his hands at an incredible speed. This drove Tails to scream in ectsasy as he climaxed hard. Shadow, however, continued stroking the vulpine's twin cocks, "Now, now, let's milk these things dry". Shadow continued pumping Tails' cocks more until the vulpine experienced a nearly endless series of orgasms. After a minute or two, Tails was left panting as Shadow wiped his hands clean before putting his gloves on. "Now then, you'll get to work on new hoverboots for me", Shadow said as he pulled out a concealed camera, "Or Cosmo and the other girls get to see this". W-WHAT?!", Tails yelled in shock. "Either you work on my new boots and increase their speed or this video will find its way on furaffinity or any other site that has yaoi fangirls", Shadow smirked as he uncoupled the fox from the table. "There are times where I really REALLY hate you, Shadow the hedgehog", Tails growled at him. "Whatever", Shadow scoffed as he left the Vulpine's lab with the camera.
