Silver's eyes widened as he finally realized just what Shadow was getting at. His jaw hung open and he was at a loss for words. The dark hedgehog had suggested a certain proposition, which he never expected from the stoic creature. 

"Well, don't just stand there with your stupid mouth open…say something!" Shadow barked. 

"I…well."

The two stood in a secluded alley in the lesser traveled parts of Metropolis Zone. Shadow specifically asked to meet there close to sunset knowing they'd be alone. The Ultimate Lifeform had always kept his sexuality a mystery, though everyone assumed he was straight with how he would casually flirt with Rouge and Blaze. However, he had just asked Silver if he was open to a blowjob. 

"Look I know you go both ways," Shadow said, folding his arms and leaning back against the wall. "I just figured you'd like to get sucked off is all." 

"Well…I mean yeah, I don't pass up a good deal, but you're not… you know…"

"What? Gay?" Shadow snapped at him. "I can't have the others knowing it, that's all. If that faker found out he'd never let me live it down. So do you want it or not? I ain't got all night."

Silver then finally realized why they met up at such a secluded place. Despite his reservations to get involved with a friend, he was in a bit of a rut. Perhaps it was why Shadow asked to meet with him in the first place. Maybe being pent up was so obvious to Shadow, despite his best efforts to hide it. He sighed and finally relented to Shadow's persistent demands for a response. 
"O…ok Shadow. Just…don't tell anyone."

"Likewise Silver. No one has to know but us. Now come lean up next to me." 
Silver did as he asked and propped himself up against the wall and tried to relax. Shadow smirked and knelt down in front of him. Running his gloved hands slowly up Silver's legs, he sniffed in front of Silver's body searching for a hint of his musk. The faint smell of the light hedgehog's slit hovered right where Shadow expected to find it. Glancing up to him, Shadow smiled. Then eagerly buried his muzzle in Silver's thick pubic fur. Darting his tongue out. He rolled it around over the area until he found the opening. Humming softly, Shadow took several long licks across Silver's quivering slit, coaxing out his dick. 

"Ah," Silver gasped, pressing his hands against the wall. 
Shadow continued licking until the tip peaked out, then he sat back on his heels. Removing his gloves, Shadow watched as Silver stiffened out of his slit. The dark hedgehog licked his lips to keep himself from drooling. Silver had an impressive 8 inch cock. It was a little thinner than the average hedgehog's, but it was a familiar smooth and tapered length which Shadow knew well from previous experience with other males. 

"Oh, yeah!" Shadow thought as he admired the shy hedgehog. 

Silver was entranced by Shadow's actions. His mouth hung open, but his face was flush. He never expected to see Shadow kneeling before him with such a lewd look on his face. Not that he was complaining about it though. Knowing what was coming next made his heart race. Silver watched the dark hedgehog return his bare fingers to his thighs, and lean in with his jaw open wide. 

"Hrumph," Shadow mumbled as he clamped his muzzle down onto the upper portion on Silver's cock. Rolling his tongue in circles, he slowly bobbed his head, getting a good taste of it. Glancing up briefly he could tell Silver was enjoying the attention. The light hedgehog was biting his lower lip. Seeing Silver's eyes close, Shadow decided to take things further. Cupping his tongue under Silver's shaft, he worked it deeper and deeper into his muzzle. Breathing slowly through his nose, Shadow relaxed the muscles in his neck and prepared to take in everything. His black fingers shifted to the back of Silver's legs, and with a deep breath he slid the entire length of the hedgehog's cock down his throat. 

"AH!" Silver gasped, feeling the warm, wetness of Shadow envelope him. His eyelids shot open and he tilted his head down to see Shadow's snout pressed against his pubic fur. Shadow wiggled his head from side to side, pleasuring Silver's cock within his throat. After a few seconds he pulled back his head, then taking another deep breath he went all the way in again without hesitation. 
"Holy ssssssshit! SHADOW!!!" Silver exclaimed. He had never had anyone deepthroat him over and over like that. He couldn't believe what a pro Shadow was at it. "Fuck, where did he learn this!?" Silver thought as Shadow continued his cycle. 

Shadow by now was almost entirely erect. His similarly long 8 inches pulsed leaking precum onto the ground. Unlike Silver though, the Ultimate Lifeform's cock was much thicker and had barbs on the underside of the shaft. A feature which made him a monster top when he felt like being one. However, Shadow was more keen on bottoming for his lovers. Not to mention how cock hungry he was all of the time. 
He had been in a bit of a rut lately as well and Silver's cock was just what he needed to quench his thirst. The lighter hedgehog tasted amazing too! Shadow sucked the precum out of Silver every time he caught his breath. The flavor drove his senses wild. If he had realized Silver had been holding out, he would have gone down on him much sooner.

SLUUUUURP!

Shadow just couldn't get enough of it. Feeling Silver's cock pulse in his throat was incredible. With each cycle in and out of his upper body, he brought his fellow hedgehog closer and closer to climax. Though it had been some time before he last enjoyed the taste of another hedgehog's hot seed, he knew just by the increased breathing of his partner and the pulse in his shaft, that Silver was about to pop. Pulling back his head, he sucked on the tip and brought his right hand up to stroke the wet length. 
"You're almost there, I can feel it," Shadow mumbled over the tip of Silver's cock. 

"FFFFFFFFAAAA…Shadow, I…" Silver could barely form a single word. Shadow was so skilled that the light hedgehog couldn't even think. He was just a slave to the pleasure now. 
"C…cumming!" Silver exclaimed as he released a massive pent up load into Shadow's mouth. 

The dark hedgehog's eyes lit up as he quickly had to gulp down the first mouthful. Then came the second stream of hot liquid followed by another, each rapidly filling his cheeks. 
GULP GULP GULP
Shadow closed his eyes as he gratefully swallowed every last drop of Silver's cum. It was just the meal the horny hedgehog needed to quench his lustful desires. Gulping down 6 mouthfuls of Silver's warm seed Shadow could feel his own dick twitch, streaming precum down between his knees. 

Silver's mind was completely blank as his climax tapered off. His backed up system was completely flushed clean, and he felt his knees wobbling in exhaustion. Shadow slurped the last from his tip, and just as his head pulled off, Silver collapsed onto the ground. His breathing was heavy. Looking up to Shadow who was sitting back on his heels he slowly gave him a relieved smile.
"T…thanks," Silver managed to get out. He hadn’t had an orgasm like that in ages, and it was even more rare to have a partner swallow his load. 

Wiping his mouth with the back of his left hand, Shadow gave a brief chuckle then reached to his own throbbing erection and began pumping it. 
"No worries Silver," he replied. "You've got a pretty tasty cock." 
Silver glanced down to see Shadow's surprisingly different member. He hadn’t really noticed before just how much thicker the dark hedgehog was. 

"Did you uh…want me to return the favor?" Silver asked, fixated on the thick instrument. 

"Nah, I'm nearly there anyw…AH!" Shadow gasped and he squeezed the base of his cock as 4 small spurts of cum spit out of him. It was remarkably less impressive than Silver's load, which caught the lighter hedgehog's attention. Letting the minimal amount of his seed fall to the ground, Shadow breathed a sigh of relief and licked the remaining drops of cum from his fingers. 

"Is that all you cum?" Silver asked, a little concerned for his friend. 

"Nah, that was my ninth one today. I'm just a little dry is all." Shadow reached for his gloves as the two of them fell flaccid again. Their dicks slipped back into their respective slits, beneath the tufts of pubic fur. Standing up, they both stretched their limbs for the run home. 

"So uh…" Silver scratched the back of his head. "Did you want to maybe do this again sometime?" 

"Hrm?" Shadow gave a side eye, as he returned to his regular stoic demeanor. A sly smile crossed his face and he turned back around.
"You enjoyed it that much?"

"No, no, it's not that!" Silver blushed and waved both hands in front of himself. "I just…ugh…" Silver sighed resigned. "Actually yeah…you're…really good at it."

Shadow smirked and rubbed his nose with one finger. 
"Well as long as you can keep your mouth shut about it…same time next week," he said, the question sounding more like a command. Shadow didn't give him a chance to respond before darting off in a cloud of dust. 

Silver was left with a tingling sensation in his chest, which led him to simply smile and shake his head from side to side. 
"Deal," Silver whispered to himself. Chasing after the dark hedgehog's trail, he already found himself hoping the week would pass by in a heartbeat.
