Chapter Text
Sonic’s room was honestly very messy. Shadow had to resist the urge to clean up all the gloves and socks off the floor and run the laundry, then come in with a vacuum cleaner and air freshener.
Sonic at least had the decency to be ashamed. “Heh, sorry ‘bout all that. I didn’t know how far we were gonna get tonight.” It was their second date, though the first read more like a hangout. Not quite sure how to bridge the gap between friends/rivals to lovers they’d competed in arcade games. Tonight was much more intimate; after eating out and going on an evening stroll, they agreed to head back to Sonic’s place. He gave his partner a chaste kiss on the lips. “Need a distraction?”
“That would be nice.” Shadow focused on those bright green eyes, and the feeling of lips on his. Sonic closed the door and led them over to the bed, having Shadow sit on the edge.
After a minute of breathless making out, a tongue slipped into his mouth. Shadow’s eyes shot open, not sure what to do. Sonic’s ungloved hand rested on his cheek, lips and tongue moving, eyes closed blissfully.
Shadow pulled away, fixated on how his lips were slick with spit. “The fuck?”
“Huh?” His partner asked mindlessly, almost dazed.
“What was that for?”
Sonic blinked, a bit more serious. “What?”
“The–your tongue,” he said, scowling to hide his embarrassment. Then, after a bit more thought, he added, “Is that normal?”
“French kissing? Uh, yeah. We don’t have to do it though.”
Another thing he didn’t know about due to his upbringing and overall solitude. “It’s fine,” Shadow mumbled, moving back to close the gap. Sonic smiled and eagerly captured his lips.
Sonic tested the waters with just a swipe, then gently slipped his tongue back in. Shadow reached up to pull them closer, accidentally knocking them back down onto the bed. Or maybe Sonic had pushed them. Who knew.
Hands wandered across his body, stopping at his thighs and giving them a squeeze. Shadow pulled a bit away to let out a shaky breath. “Why…?”
“It’ll feel good,” his partner murmured. Not eager to embarrass himself further, he nodded. Sonic moved his hands between Shadow’s legs, then— “Oh.”
“‘Oh’?” Shadow repeated incredulously.
“I just didn’t expect—” He broke eye contact for a second, flustered “— that . It’s cool though.”
“Expect what?” Shadow’s arms went slack around his partner’s neck.
“Like—y’know—a pussy…” Sonic trailed off.
Shadow’s brow furrowed, confused. “My…” Sonic nodded, and he continued, “What else would I have?”
He supposed it was a very difficult question, because Sonic had to duck his head as he spoke, “Ah, uh, if we’re gonna… um, maybe we should do this another time.”
“I’m fine. It’s just a question.”
Sonic kissed his brow. “I know, I know. I just, y’know, don’t want to freak you out or anything. Can’t imagine your face when you… nevermind.”
“Don’t patronize me. I can handle it,” Shadow insisted, suddenly fed up. His arms fell back to his sides. “It’s only biology.”
“Do you really wanna talk about this now?” Sonic asked, voice strained. Shadow gave him a hard look.
His partner gave a tense smile. “Uh, alrighty then. I guess I’d have to do this at some point.” He moved to sit upright, across from Shadow on the bed. “So like…” Sonic hid his face for a second before continuing hurriedly, “You have that. Right? I have the thing that goes in. Get it now?”
Even he could tell that Sonic was immensely uncomfortable. “I understand it well enough,” he said gruffly. “Are you going to… show me?”
“Cool, cool,” Sonic said, leaning forward again, “Ah. Maybe another time.”
Shadow closed the gap, pulling them back into their original position. He didn’t understand the appeal of kissing at first; it was something he did occasionally because it made Sonic happy. But eventually he grew to understand it. It filled him with warmth, love and passion in a way that nothing else could. Or rather, it used to be the only thing that could—
His breath hitched as fingers began rubbing around his pussy. His mind went blank. He’d only ever felt a sensation remotely close when he sneezed or itched or rubbed behind the ears.
“You still with me, Shads?” Sonic had the audacity to break the kiss to laugh as he adjusted his position, fingers finding a spot that made him choke back a whine.
“What’re you doing?” He managed to get out just as his partner moved to tease closer to the slit between his thighs.
“Making you feel damn good by the looks of things,” he murmured, “Just trust me, baby.” With that, he moved to his pussy, fingers cool against his hot, hot skin. “Fuck, you’re wet.”
“I—” Shadow didn’t get the chance to finish asking what that meant. Sonic slipped a finger in, curving it and moving inside. Shadow bit his lip, eyes wide at the sensation. Really, what the actual hell now?
“Trust me,” Sonic muttered again, “You’ll like this… then later we can have a whole talk about anatomy. Or we can just find a book for you to read. I think that’d be less painful.” He gave his partner a kiss, then his thumb went back to work on the outside of his pussy.
A quiet “fuck” slipped out as pleasure radiated from that spot. And Sonic’s finger… as strange as it felt, it also seemed natural. Fire built inside of him as he stroked and moved inside. His muzzle blushing furiously, Shadow covered his mouth with a hand.
“Lemme hear you,” Sonic said, his voice a bit harsh. He seemed a bit embarrassed by that, softening his gaze as he pulled Shadow’s hand away. “C’mon, I’m doing all this work over here.” He eased another finger in. There was a bit more resistance, not sliding in as easily as the first.
He let himself moan. His thighs twitched, stuck between clamping down and closing off or opening up, allowing for more and more. Sonic snickered breathlessly, fingers pumping and curling. Shadow groaned, “F-Fuck, fuck, Sonic I—”
“You’re a mess,” he mumbled, quickening his pace. Sonic’s eyes were narrowed in concentration, face flustered, other hand wandering on his own body but not touching between his legs.
“Shit, hah, you fucking…” Shadow couldn’t think of any insult. Heat began to build inside him and he let out a pitiful whine. “What’s — oh, shitfuck — what’s happening?”
“Hmm,” Sonic said playfully, “I wonder…” Shadow’s ears pressed flat against his head at the tone.
“Stop withholding information from me,” he barked, the feeling between his thighs admittedly removing some of the edge to his voice.
“Aw, is that any way to talk to your partner?” Sonic gave one last thrust up with his fingers, then pulled out. The… buildup already began to fizzle out, and he felt strangely empty.
“You motherfucker,” Shadow hissed. He closed his thighs, rubbing and trying to get the feeling back. In the back of his mind he was embarrassed— he’d never felt this way before, so desperate and left in the dark.
“Guess you still haven’t learned your lesson,” Sonic said slyly, pulling Shadow’s legs apart. As he did, Shadow caught a glimpse of his partner’s fingers and instantly understood what “wet” meant.
“Did I—” He glanced down. Some clear, thick fluid coated his slit, matting the fur around it.
“Looks like we need to clean that up, huh?” Sonic leaned down to kiss the opening, and Shadow sucked in a breath. “Just promise you’ll quit misbehaving. Or I’ll have to stop again, and neither of us wants that, right?”
Blushing, he looked away, though the space between his legs heated in anticipation. Sonic chuckled. “I’ll take that as a yes.” His tongue began to play with the outside of his pussy, licking up the fluid and slipping in and out. Shadow keened, letting out a sharp whine. He immediately clapped a hand over his mouth.
Sonic moved away, eyes dark and heavy lidded but with a gleam of playfulness. “What’d I just say?” He pulled Shadow’s hand off of his face then, luckily, went straight back to licking and teasing his slit.
“ Fuck, ” he whispered. The pressure inside him began to build again, much faster than before. “Fuck, Sonic, babe, what’s gonna happen?”
“I think you need to get your ears checked,” Sonic replied between licks, “‘Cause I told you to trust me.”
He grunted in reply, his noise immediately devolving into a moan as he flicked his tongue at some part at the tip of his pussy. Heat and pleasure sprang from the spot. “S-Shit,” Shadow gasped, breaths shallow, “Oh my god, fuck. Sonic—hah—feels so good.”
“Mmm,” his partner hummed, muzzle flushed. He pulled away but his tongue was immediately replaced with his fingers, teasing the same spot. “You’re so fucking hot… so needy…”
“Yeah,” Shadow agreed mindlessly, unconsciously rolling his hips forward for more, “Yeah—shit.”
“God, I wanna hear you when I fuck your brains out,” Sonic said, voice low. “You’re gonna lose your damn mind.”
He didn’t know how to respond, not wanting to admit not understanding yet another thing. Instead, he groaned, thighs twitching. “S-Sonic. Hah, fuck, I—I feel—”
“Mm, cum for me, baby,” Sonic murmured, petting his partner’s muzzle gently. His fingers sped up, thrusting in and out with an obscene sound. He added another finger, earning a gasp.
“Shit—nnn—fuck, fuck, FUCK —” Shadow felt (as best as he could put it) an explosion. Heat and pleasure racked his body, and he might’ve whimpered yet again. His back arched, and his thighs clenched.
“You’re so fucking wet.” His partner pulled his fingers out slowly, revealing just how much of the fluid he’d leaked. Shadow closed his eyes and turned his head away, panting.
“Aw, c’mon, don’t be like that,” Sonic chuckled, “Did you enjoy yourself?”
“...You know the answer,” he mumbled.
Sonic snickered again, eyeing him up and down. “Oh, I do. You’re so sexy, y’know that?” He moved to his partner’s neck, leaving kisses and small licks. “So good. You did so well.”
Shadow didn’t have anything to say, still feeling wrecked. His slit tingled. Sonic happily filled the silence, “You were fast but I guess I should’ve expected that. Dude, have you really never even played with yourself down there?”
“You know it pisses me off when you call me that,” Shadow finally mumbled, “And… no, I didn’t know that was an option.”
“Sorry. Just a habit.” Sonic gave a quick kiss on the cheek as an apology. “You should try it. And let me watch.”
Shadow wrinkled his nose. “How about I learn a bit more about what the hell just happened first.”
“Sure thing,” he said. They kissed again. “Do you wanna take a shower? I can join you in a bit, I need to take care of myself real quick though.”
Shadow’s eyes trailed down to Sonic’s crotch, noting how he covered it with a hand. “I’m not gonna ‘freak out’... you can show me.”
He hesitated but relented, slowly revealing the thing between his legs. Shadow’s eyes widened for a moment, then he relaxed. The vein was a little weird but besides that it was pretty much what he expected for “the thing that goes in”.
“See, I didn’t start screaming and crying,” Shadow deadpanned. Though his eyes were still on it , brain racing. It was supposed to go in… wouldn’t that hurt? And was it not normal to have a pussy? Why did Sonic have that ?
“Alright, alright, I get it,” Sonic chuckled good naturedly, “Just wanted to warn ya. So. About that shower…? Unless you want to watch?”
“I’ll go.” Shadow figured that he had enough exposure for one day. “Have fun.” He stood, legs admittedly a bit shaky. His insides ached too, but it was nothing he couldn’t handle.
“Oh, I definitely will,” he winked.
