Bucky the Rat was finally free. Having made a deal with GUN, providing a revolutionary invention in exchange for his freedom, he set up shop in Central City and was now able to put his mind on experimentation ahead of self-preservation. After a few weeks, he began advertising his latest breakthrough: he claimed to have created a sort of vaccine, which would protect against all manner of sexually-transmitted issues, from common STDs to unplanned pregnancy. Of course, after the GeneXXX Wave incident, many were skeptical. However, with confirmation from other, more reputable scientists, Bucky's "safe-sex" vaccine started to generate interest. Bucky had to caution each taker of the vaccine, however, that the desire to become pregnant could overcome the vaccine's effect, since it is essentially a GeneX-based vaccine being assaulted by GeneX-force, and if both parents are willing, it's in fate's hands at that point.

Why mention all this? It is where our tale begins...

Bucky offered a free vaccination to all the victims of his GeneXXX Wave scheme, hoping to mend fences with them. It took some time, but all agreed to it. One of the last to get the vaccine was Blaze, who had to come from a whole dimension away in order to get it, but she was one of Bucky's victims, so she got it for free. They avoided chit-chat during the visit, mostly, but there was one question Bucky asked each who got the vaccine. "Any plans now that you can make love without fear?" he asked. Blaze glared at him a little as she felt the pinch from the needle, but as she started to head for the door, she nodded slowly. "There is someone I miss..." she sighed longingly.

On her way out of the lab, she passed the previous "customer," Katie the coyote, who was waiting for her ride home along with her young "escort", Tommy the porcupine. Blaze looked at Tommy and felt a strange chill, but shrugged it off and kept going. Katie sighed as she waited. "I don't know why I did this... Since Chet's gone..." she sighed sadly. Tommy looked at her sympathetically. "You'll be happy again, Katie. Don't worry. I remember feeling bummed when my mom died..." he said. Katie looked at him with a light smile. "You are so sweet..." she said, wondering why she was looking at him like she was. Bucky watched this through a window of his lab, chuckling softly. "GeneXXX was too disruptive to free will... This strategy will work out better..." he mused.

Blaze wasn't entirely sure where to go, but she figured she probably shouldn't rush to do anything before the vaccine had a chance to set in. Since she was in Central City, she figured she should probably pay a royal visit to the president, so she started on the way to the presidential office begrudgingly. Sometimes being the princess was a real bore. Along the way, she felt like someone was watching her. She shrugged it off and kept going, until suddenly she heard some shots fired in her direction! Before she could do anything, she felt herself lifted into the air, out of the path of the shots! "Stay calm! I've got this!" Her ears pricked as Silver's voice met them. The white-furred hedgehog stepped under where Blaze had been, and waved his hand, pulling the robots out of their hiding places and smashing them on the ground with his psychokinesis! "...Another tragedy averted..." he sighed, setting a blushing Blaze on the ground gently. "I... I could've handled that..." she said. "Not that time... They caught you by surprise." he stated. Blaze nodded slowly. She realized it was futile to argue with him. He was from the future. He was already starting to leave, so she grabbed his arm. "Hey, wait...! Aren't you going to let me thank you?" she said hastily. Silver shrugged. "This is what I do. No thanks are necessary." he said. She wouldn't let go of his hand, however. "Please... come with me." she said insistently. Silver looked her right in the eyes, and something about her gaze made his own expression soften. "Uh... Okay. Lead the way..." he said awkwardly.

They came to a quiet alleyway in a calm section of the city. There weren't many places Blaze could think of to go. Here, she began by stealing a kiss from the hedgehog, startling him enough that she could back him against the wall. "You don't remember... but we have been close friends for many, many years... And I miss you so much, Silver..." she whispered. Silver stammered. "Years...?" To him, they'd first met sometime after he started traveling to Sonic's time. "Never mind the long explanation, Silver... You know about time travel, and that should be enough..." she sighed, starting to tug at her clothing as her passion started to ignite! Silver gulped, unsure what to make of this seemingly sudden change in his friend's demeanor. However, as she kissed him again, he started to moan into it and kiss back, realizing that this somehow felt right. His eyes glowed and his hands rose around Blaze's sides, his powers easing her coat off of her body and placing it on the floor. Blaze giggled, and went to work on the white tights that she wore underneath. Silver watched in wonder as her lavender fur slowly escaped from the tight confines of her clothes, and as her tights were tossed to the floor, Silver could see it all, her small but cute breasts and her wet, waiting pussy. He started to get hard, and she purred, nuzzling his cheek with her nose. "Finally... After all this time... Make love to me, Silver!"

"Y-you're...beautiful...!" Silver gasped, still grasping what was happening slowly. His cock started to bridge the tight gap between them, poking Blaze's belly. She glanced down at his rapidly perking up member with a smile. She backed up slightly, parting her legs a bit. "Glad you're pleased..." she purred. Silver looked her over again, and he started to blush as he came to fully understand what was happening. "...Man, I hope that shot Bucky gave me works... I don't want to be a dad in the past..." he mumbled. Blaze suddenly pounced at him, her lips pressing against his, silencing him and exciting him all at once. As their mouths opened and their tongues met, Silver made his first bold move, and slid his cock forward, finding her pussy and slowly entering. Its warm, wet embrace felt familiar, like this wasn't actually their first time together. Blaze shivered. She felt the mysterious familiarity, too. The GeneXXX Wave had wiped their memories, but they had done this before. Blaze held on to Silver's sides, gazing into his eyes and waiting for him to jog her memory further. He slowly started to push his hips forward, sliding his cock deeper into her pussy. It felt good, and he found himself thrusting back and forth inside her at a brisk pace before long! Blaze held him against the alley wall as his hips bucked against hers, coaxing soft moans from her lips. She feverishly seized him in a tight embrace, her fingers running through his soft, silvery fur as her hips started to rock against his. "Aaahhh... B-blaze...!" Silver gasped, his own hands slowly returning her embrace, holding her much more gently as his cock thrusted faster, filling them both with exquisite pleasure. Blaze kissed his neck, purring as the intensity picked up. Her breasts pressed against his fluffy chest as she pulled him closer. "Ohhhh... Keep loving me, Silver... Like I love you..." she moaned. Silver's eyes widened at those words, but only for an instant. In the heat of the moment, he could feel nothing but love for Blaze, as well. He nuzzled her cheek and gently grabbed her butt as he started thrusting as fast as he could! She let out a joyful meow as Silver found his way to her sweet spot, and she followed this by kissing him deeply and hungrily! This nearly broke their momentum, but his moans indicated Silver didn't mind. He could feel the pleasure building in his cock, and he knew it would end soon. His eyes gazing into hers said it all. Blaze nodded and seized his waist, slapping her hips against his eagerly. "Do it, Silver!! I want to feel closer to you than ever!" she moaned. He blushed and gave a few more thrusts, crying out loudly as he came! His seed shot deep and forcefully into her depths, while he held her ever so gently. "Thanks, Blaze... You're very special to me..." he said softly. Blaze cuddled up to him and purred as she felt a warm fullness from his load. "Let's do this again... In a more intimate setting..." she said, nuzzling him softly. Indeed, the alley wasn't very intimate. Though they hadn't noticed, a dark figure had been watching them, and now stepped away since they were finished...

Meanwhile, Katie and Tommy had made the trip back to Station Square, and were walking to Katie's house. The whole way, she felt an odd sense of excitement in the young porcupine's presence. She didn't understand it. Was there something more to the vaccine than Bucky had said? She tried to ignore the desire welling up within her, but Tommy could tell something was off. "Katie? ...You're staring at me a lot. Are my quills messed up?" he wondered. She shook her head quickly and adjusted her gaze straight ahead. "Errr... No. Everything's fine! Hey, uh... How old are you?" she murmured. Tommy crossed his arms. "I'm old enough to know you're acting weird..." he grunted. He was about Tails' age, but he wasn't quite as emotionally mature, so Katie gritted her teeth and tried to remain silent until they got to her house. Once there, she rushed to open the door, but Tommy started after her. "You seem freaked about something. Maybe I should stay for a while and make sure you're okay. My bro would be mad if I left you and something was wrong..." he said. Katie shook her head frantically as she rushed inside. "No, no, nothing's wrong!" she yelled. Tommy reached over and put a hand on her shoulder. "Relax... You can tell me what's bothering you. I'm not just some kid. I'm your friend." he said. Katie sighed, and let him into the house. "You might be sorry..." she muttered.

She led Tommy to her sofa and motioned for him to sit down. She sighed, knowing what her body wanted. Tommy looked at her curiously, and then yelped as she started to undress in front of him! He held his eyes as her shirt flew at his feet. "W-what're you doing?? A-are ya crazy?!" he stammered. He felt something land on his head. Something that cupped over each of his ears... He gasped as he realized it was her bra! Katie giggled. "C'mon, Tommy... You're getting big now... Don't you want to learn about how boys and girls bodies work...together?" she purred. Tommy felt her hands over his, guiding them away from his eyes. As she backed away, he slowly opened his eyes and got his first sight of true female beauty. Katie stood, fully nude, her dark-furred breasts the first thing the young porcupine's gaze fixed on. He felt a strange stirring between his legs as he slowly glanced down Katie's body, noting the wet folds between her legs. "K-katie...!" he stammered, unsure what to say or do. Katie smirked as she saw his yellow-furred virgin rod starting to rise. "Time to teach you, Tommy..." she grinned.

Katie held on to his shoulders, leaning down and pressing her lips to his, her tongue parting them and entering his mouth eagerly. Tommy squealed, his face bright red and his eyes darting everywhere as he tried to come to grips with what was happening. As his tongue mingled with Katie's, the kiss gradually calmed his nerves, and he rested his hands against her sides. Katie chuckled as she parted her lips from his. "Now that you feel better, take a good look at me..." she said, rolling onto the couch beside him and laying herself out to give him a good view. "What do you think you should do next?" she purred. He looked her over slowly, blushing as he thought this through. He looked down at his own body, and back at hers. "We... fit together..." he gasped, crawling up to her and pointing his cock down at her entrance, a look of awe on his face. She nodded. "Put it in... See what happens when we combine..." she winked. He giggled softly at her wording. "Uh... Okay..." he said, still blushing as he carefully pushed into her, gasping as he felt her wetness. She reached up, pulling him closer as he pushed inside her. She stroked his quills and purred softly. "That feels nice... Now just move it back and forth..." she told him. "L-like this?" Tommy murmured, slowly sliding his hips forward and backward, pushing in and pulling out. He let out a cute moan as he started to feel sexual pleasure for the first time. She cuddled the yellow porcupine closely as he finally got going. "Ahhh, yesss... That's it, Tom... You're making love to me now..." she sighed. His eyes widened at the idea, but then he smirked softly. "Well... you did need some love..." he smiled. Feeling a bit mischievous, he slid his hands to her soft dark-furred breasts and gave them a little squeeze. "Hehe! I always wanted to try that!" he giggled. Katie smiled as he loosened up, and moaned as his motions picked up speed. "Glad to help you live some fantasies, cutie..." she blushed, feeling him hold onto her boobs as he kept going. He shut his eyes and kept going, thrusting his hips roughly and eagerly hoping to please Katie. Soon, he felt an unusual feeling in his crotch. "Ahh!! Wh-what's happening to me...??" he gasped. Katie was busy moaning, but she composed herself to reassure the nearly no-longer-virgin porcupine. "Are you gonna cum? Ahhhh... It's okay... Let it happen... Oooooh... It'll feel... great!" she gasped. His hands moved down to her sides as he leaned up to kiss her, moaning into her mouth as he got closer and closer to his climax. She moaned out his name suddenly as she came a little herself. "Impressive for a first-timer!" she panted. Tommy gasped loudly as he finally came as well, painting her walls with his first-ever spray of seed! He then collapsed into her arms. "Wow... I'm tired... but it felt good..." he sighed.

As they rested together, the dark figure from Central City was outside, walking toward a vacant house down the street. Inside, this being found a blackboard. Waving its hands, this being caused glowing lettering to appear on the board. It read as follows: 
Silver - Blaze (1)
Tommy - Katie (1)

The dark figure lifted a pointed hat from her head, revealing bright orange fur. "The game has begun..." she murmured, turning away from the blackboard. "I, Tabitha, will be watching the players quite closely... Until the time is right..."
