Curiosity

Sonic's POV

"Hedgehog?"
"Yeah?"
"What does sex feel like?"
I choked on my drink as Shadow asked me this question. I coughed and tried to get as much of my drink out of my lungs as I possibly could.
"What?!" I asked in shock, my voice breaking a little.
Shadow looked at me, slightly surprised as he had not expected me to react this way.
"You heard me!" He stated as he diverted his attention back to his book, not wanting to ask this question twice.
"And why do you bring that up?" I asked, silently thankful that Tails was having a sleepover at Cream's house along with Charmy and wasn't around now that Shadow brought this subject up.
Shadow didn't seem to know how to answer my question at first. He needed a moment to think about it. Should he answer truthfully or come up with some sort of lie?
"I'm... just... curious." He decided to give a more honest answer as lying was really not something he liked to do. And not just because he didn't very much appreciate it himself, but also because he wasn't very good at it either.
He tried to lie to Rouge a few times and quickly discovered that, no matter how hard he tried, he always failed epicly.
"Okay? Well... If you're really curious, I guess you can think about doing it when you have a girlfriend... Or a boyfriend, if you like guys that way." I hesitantly answered. I didn't really know what to answer.
That last part was quickly added in case Shadow happened to swing that way. You may think that, as a hero, it's only natural for me to be accepting towards everyone, no matter what species, gender or sexuality. And while I was, the fear of bearing the consequences of insulting the hedgehog next to me was far greater.
"Hmpf, strange. That's what Rouge told me too. Well, before she told me to go ask you next time I came over." Shadow replied.
'Did she now? What's up with shoving that responsibility onto me? Shadow's her best friend, isn't he?' I thought as I took another sip from my drink.
"And besides, I don't want to have sex with someone I don't know. I'd rather do it with someone I'm currently acquainted with." Shadow added as he closed the book he was reading and placed it on the coffee table in front of us before leaning back on the couch and crossing both his arms and legs.
"Someone you know, huh..." I muttered. Soon after a thought occured to me and I couldn't help but chuckle, which made Shadow look at me in question.
"If you want to have sex with someone you know, why don't you head up to Angel Island and hook up with Knuckles? I'm sure he'll love having some real company instead of that rock of his." I continued to chuckle. Shadow couldn't fight a small smile either.
"But seriously now, Hedgehog, I would much rather want to sleep with you instead of Knuckles." He told me.
"With me huh...." I muttered, my voice trailing off as the thought of us doing it entered my mind.
Heh, now I was getting curious aswell.
"Wanna do it?" I ased, my gaze resting on the hedgehog besides me.
Shadow looked back at me. He looked like he was actually considering it. He really wasn't joking when he said he would want to do it with me.
"Yes, I want to do it. Right now." He had barely even finished his sentence when I pressed my lips against his. A sound of surprise left Shadow as he had not expected me to kiss him already. But soon enough he, hesitantly, returned the kiss.
I was pleasantly surprised to find Shadow's lips to be very soft. And judging by how he deepened the kiss and wrapped his arms around my neck, he seemed to enjoy it too.
"How was that for a first kiss?" I asked with a slight smirk after we broke away. If Shadow was as much as a virgin as I thought he was, this must be his first time kissing someone.
"I guess it was alright." He teased me as he leant back in for a kiss, which I didn't deny him.
"You're not so bad yourself." I replied in between kisses, my arms moving to wrap around Shadow's waist to pull him close.
I let my tongue slip past to lick over the ebony's lips, which caught him by surprise a little before he figured he should seperate his lips and let it through. I had to refrain from smirking as I heard Shadow moan softly because of this new experience.
I explored every nook and cranny in his mouth and let my tongue play with his. Shadow was trying his best to keep up with something he had absolutely no experience with. It was actually kinda cute.
Shadow was the first to pull away, panting lightly and an uncharacteristic light blush out of either embarrassment or heat made itself isible on his tan muzzle. The sight made me chuckle.
"Do you have any idea how adorable you look right now?" I asked as I leant down to kiss his neck.
"Sonic..." Shadow called my name softly as my lips trailed his neck and made their way to his shoulder, which was still covered by the button-up shirt he wore. So I removed it, slowly unbuttoning the clothing article and sliding it down his shoulder and allow me access to it.
"Ah... Damn..." The hedgehog cursed himself as his breathing became faster and occasional soft moans left his vocals. He had not anticipated simple touches like this could affect him so heavily.
I smirked as I felt his body shiver under my touch as my hands explored the entirety of his torso, my fingers stroking through the fur on his back and the soft, white chestfur adorning his chest.
Shadow decided to retaliate, grabbing a handful of my quills to pull my head back so he could attack my lips with his own, slipping his tongue between my lips and letting it play with my own.
I groaned as Shadow moved his hands away from my head and neck and instead felt them sneak under my shirt to wander over my abdominal muscles and stroke through my own fur before he pulled my shirt of my head. He was learning just from feeling how I did it to him.
"Sonic!" I managed to catch him by surprise as one of my hands moved down to his crotch while he was too busy trying to work my shirt off to notice my hand. He just managed to keep himself from jumping up from the couch as I rubbed his crotch, squeezing it a little even.
"Not there..." He breathed as I continued to tease that area, although he didn't make an attempt to pull away from me.
Man, seeing and feeling him writhe and shiver under my touch and hearing the occasional surpressed noises he made was turning me on. The tight and cramped place my jeans had suddenly become made sure I knew that.
"Sonic... Maybe we shouldn't do this..." Shadow began to have second thoughts as I pulled his shirt off of his body and allowed our naked chests to touch as I resumed kissing his shoulder and neck, occasionally going to his collarbone aswell.
"Don't worry, It'll be fine." I reassured him as I attempted to push him down on the couch, but Shadow pushed me away instead.
"Can we atleast take this to the bed? I don't think the couch is a suitable place to have sex on." He said, glancing down at the furniture we sat upon.
"Actually the couch isn't such a bad place to have sex on. But sure, we can continue this in bed if you prefer it that way." I responded as I stood up from my couch. Shadow was about to follow my example when I decided to pick him up in my arms in a bridal-like style.
"Hedgehog!" Shadow yelped in surprise and quickly wrapped his arms around my neck to keep himself from falling.
I couldn't help but chuckle at how tightly he held onto me. He definitely hadn't been carried like this before.
I ignored any further complaints or disagreements as I brought him up the stairs and into the master bedroom and gently lower him down on top of the covers. His head rested on the pillows as he watched me, his eyes glued on my form as I unbuttoned my jeans and kicked them off along with my shoes and socks.
My smirk widened as I noticed Shadow staring at the bulge in my boxers with a look of shock. I wasn't the only one excited here, though. His own bulge told me that.
"Don't worry, I'm pretty sure it can fit inside the Ultimate Ass." I reassured him, as I did sense a bit of worry in his expression, as I moved to lie down on top of him. Being pinned down by my body was a feeling Shadow needed to get used to before he felt comfortable enough to let me continued exploring his body and kissing.
"My... My ass? The hell? You don't have any business with my ass." Shadow looked at me like I had just said something weird.
I took a brief break from trailing my way down his chest and belly with my lips to chuckle.
"Of course your ass, or butt if you prefer that word. Where else do you think I'm gonna cum? I'm sure as hell not bottom today." I stated as if that should've been obvious.
"And why the hell not?! What gives you the right to be top?" Shadow argued, obviously a little apprehensive to the thought of having me cum inside of him like that.
"Experience, that's what." I simply answered as I unbuttoned his pants before pulling it off, after getting rid of his shoes of course.
"Why there, though?" Shadow muttered in confusion, seemingly not understanding why I was so keen on using his butt, while I kept myself busy with the ebony inner thighs, kissing the inner side of them.
"Sonic... Huh... Before you, huh..." As soon as I gripped the waistband of his boxers, Shadow became uncharacteristicly nervous.
"Hmm? What's up?" I asked, somewhat worried as I didn't know Shadow to be one to get nervous easily.
"Nevermind." He said as he suddenly changed his mind, looking away from me.
I shrugged it away and continued to pull his boxers off of his shapely butt. Usually I would've pestered him about what could possible be bothering him as I did with all of my friends, but my boner didn't let me. Not that it mattered because when I did get his underwear off, I figured I had found the reason behind his apprehension.
His hard-on, while unexpected for the infamous Ultimate Lifeform, failed to distract me from the wet lips and fur behind it.
"So... An hermaphrodite, huh? This just got a whole lot better!" I stated with a smirk, slightly teasing the hedgehog lying in front of me. Now that I think of it, I think his double gender might be the reason he didn't even question doing it with the same gender as him.
"Just shut up and fuck me already." Shadow growled lightly, clearly not liking someone talking about his true gender.
I just chuckled in response, which seemed to annoy him even more. Not to worry, though, I can get rid of his annoyence.
I pulled my own boxers off and revealed the erection I sported, which already seemed to have whisked his annoyence away.
"Hedgehog, you can't put that into me! It won't fit..." He muttered the last part, but I still heard it clearly. I would've smirked wider if it was possible to do so without looking creepy.
"Oh, don't worry, I'll make sure it will." I answered as I spread his legs, to allow myself to have the space I need, and moved my hand to his lower lips, seperating them and taking a look at where I would force my way inside soon. His opening was just the way I liked it. Wet and ready to be used.
"Pervert..." I heard him mutter as I stared at his untouched pussy. I could hardly believe I was gonna be his first.
Shadow gasped and nearly closed his legs as I let my fingers stroke in between his two vaginal lips, pleasuring the clitoris they hid. His hands grasped the blanket he laid upon as I continued to stroke something so sensitive, the tips of my fingers teasing the small entrance itself before I entered my middle finger inside.
"Sonic... What're you..." He didn't finish his sentence as he suddenly felt the strange, but pleasurable, feeling of my finger intruding him.
"Don't worry, I know what I'm doing." I reassured him as I knew what he had been wanting to ask me, pulling my finger out before pushing it back in, fingering him and drawing more moans and gasps out of him.
"I... I noticed." Shadow moaned softly along with the rythm of my finger, soon enough enjoying the feeling of my index and even my ring finger enter the tight space, although the third one seemed to be a bit too much.
"yeah, if you can't handle three of my fingers, I don't think my dick is gonna fit in there either. I guess I'll have to use your butt anyway. Or I can just force my away inside." I teased my ebony hedgehog as I kept up the pace.
"W-What? I...I don't think-" Shadow was obviously having second thoughts after my tease, seriously believing my words somehow.
"I'm just kidding. I'll show you how much of a perfect fit you and I can be." I growled out in excitement as I simply couldn't wait until I could take him and make him mine, pulling my fingers out and gripping his hips to lift them up.
"Sonic..." Shadow muttered in uncertainty as I took my member and aligned it with his virgin hole.
"Don't worry... It'll be fine." I reassured him one last time before I pushed the tip into his entrance and instantly felt this wet, hot embrace around my member. Shadow bit down on his lower lip as he felt a little uncomfortable with being entered for the very first time.
I even heard him whimper as his eyes narrowed in pain, as I intruded further inside and slowly and carefully broke through his hymen. His breathing quickened and I groaned at the tight feeling. It was getting difficult to get any further.
"Shadow, you might want to try and relax, otherwise this won't be very memorable for either of us." I advised and Shadow tried to follow it, although it wasn't exactly easy for him.
I finally got myself inside all the way, my tip resting against his cervix.
"Sonic... Is it normal that this hurts?" Shadow asked, obviously still feeling the aftermath of having his hymen torn open.
"For your very first time, yeah. Don't worry, it'll feel better once you get used to me." I let the teasing go for now, deciding that it was more important for Shadow to feel comfortable. My smirk was no longer present either.
We stayed like this for a long while, my dick still buried deeply in his vagina. But we didn't just sit still as we waited for Shadow to adjust. We filled the time by making out and letting our hands wander over eachothers bodies further, taking his mind off of the stinging too.
Shadow, while having a difficult time getting adjusted to me, soon began to gasp again whenever I moved my hips. So I figured he was ready. Carefully I pulled my erection out of him and pushed it back in just as carefully and awaited his reaction.
"Eh? W-What was that?" Shadow was so surprised with the new feeling he felt that he even stuttered a little.
I smirked slightly once more as I knew the pain had faded to make way for pleasure. And that was what he felt.
I pulled my member out and let myself breath in relief at feeling Shadow's tight embrace slip off me until just my tip remained inside and I thrusted back in. The tight and hot hold Shadow had on my erection made me groan in pleasure. His juices covered more and more of my member the more I thrusted inside and our moans and groans grew aswell.
"S... Sonic.... Pl... Please tell me that I.... That I'm not hallucinating this pleasure..." Shadow begged me to answer, wanting to know if this pleasure he was feeling was real or not.
"Oh, yeah, it's real." I answered, picking up the pace a little and letting our hips meet over and over again.
"Ah, yes! I'm so glad I'm doing this with you!" Shadow stated as he quickly let the pleasure sweep him away.
"And I'm so glad you choose me as your first." I replied as I thrusted all the way inside again, earning myself a loud moan.
"Getting vocal, huh?" I teased as I slammed my hips against his just to see how he would react.
"Oh fuck! Please, do that again!" He swore and pleaded, eagerly wanting to feel that again.
"I misjudged you, Shads. I always thought you were the kind of person to enjoy a more gentler approach with sex, but instead I discover you like rough sex more. But hell, that'll just make it more enjoyable for me." I said as I did what he asked, tightening my grip on his hips and beginning a harder and faster rythm, pretty much getting close to pounding away at that pussy of his.
"Oh... Ah! Sonic! Just like that!" Shadow moaned, his juices continued to leak out of him and coat both me and the bed. It didn't take long for these wet sounds to fill the room.
"Ah! So...So close... Already." I could hear him moan, so I pulled out.
"Sonic?" Shadow called my name in confusion, not understanding why I had suddenly pulled out of him after I seemed to be enjoying myself alot.
"Turn around." I practically ordered, although I didn't mean for it to sound that way.
Shadow just stared at me in confusion, not really sure why he should.
"Just turn around like this." I repeated and helped Shadow with rolling onto his stomach, even though he really didn't need any help.
"Lift your butt up." I said and he did exactly that, putting his butt in the air as he sat on his hands and knees.
In this position, I got an even better look of his vagina. It was so wet. His juices slowly rolled down and coated his more masculine gender aswell.
"Sonic? What're you waiting for?" Shadow asked. He was looking at me from over his shoulder.
"Oh, nothing. Just enjoying the view." I answered, letting my hands wander over and squeeze that nice butt of his. Man, no wonder he's called the Ultimate Lifeform. His butt and vagina truly live up to that title.
Once more I chuckled as I heard a groan of dissapointment leave him. He wanted me to continue so badly.
So I didn't let him wait any longer.
I took my wet manhood and aligned it with his entrance. I teased him a little by pushing my tip against his opening, just threatening to enter him. But I didn't when a thought popped into my head.
"Damn you, Sonic..." Shadow cursed me as his legs trembled in need.
"For my personal satisfaction I want to hear you beg for it." I stated.
"Wha?! No way! I am not begging for your penis, Sonic!" He snapped back at me.
I acted as if I was slightly insulted before letting go of his hips and moving away just a tad bit.
"Sonic?" He called my name, just a tad bit worried now.
"Hey, I don't mind stopping your first time right here. I can just go to the bathroom and jerk off there. It's really not a problem to me." I said and moved to step off the bed, I had enough mental material to finish myself up, but Shadow stopped me.
"Okay, okay! I... Want you inside.. Okay?" He quickly said, hoping that would be enough.
"Well, you certainly got my attention now." I said, placing my hands on his butt again to try and urge him to continue.
Shadow looked away from me, obviously not wanting to beg to get banged. But judging by the way his body trembled in need, he needed me inside him. Badly.
"P-Please... Sonic... Please, I need you. Don't leave me like this..." He begged, his ears flattening in submission. He really didn't like pleading me for something like this. Heck, he didn't like pleading period.
"I guess I can accept that for now, but we'll have to work on that next time." Once again I teased him, but Shadow seemed to take it to heart.
"Like hell you're turning me into some sort of love slave for your- Ah!" I didn't let Shadow finish as I plunged my member back inside him, going in all the way with one swift thrust and hitting his cervix.
That shut him up for a moment or two.
"D-Damn you... Sonic..." Shadow moaned, his mouth hanging open as he panted and gasped, his hands holding a tight grip on the pillow underneath us.
"So... So close." I heard him mutter as it didn't take long to get him close to his climax again. And I knew just the thing to get him off.
I thrusted my manhood inside all the way up to the root and leant down to wrap my arms around him, kiss his upper back and shoulder as I did so.
"Sonic? What're you- Oh Chaos! Not there!" Shadow yelped in surprise like the virgin he was as I moved one hand between his legs to play with his clit while my other hand wrapped around his very neglected shaft, pumping it and delivering the ebony hedgehog a whole new kind of feeling.
Just as I predicted, that was the final straw.
"Oh Chaos! Sonic, I'm cumming!" He shouted as his whole body tensed up, a wave of pleasure without a doubt washing over him as his first orgasm took him by surprise. His inner walls clenched down on my length and sperm came shooting out of his own member, coating the bed covers below and my hand.
Shadow just sat there on his hands and knees, panting as he enjoyed the aftermath. His whole body trembled even more than before and he wanted nothing more than to give in to the exhaustion that had suddenly taken over his body, but that would be a little difficult since I still had my own dick buried inside of him.
"I... I have to admit that felt... Great..." Shadow managed to speak in between his pants.
"Yeah, you do, but I'm not done yet." I said as I straightened up and took his hips again. I pulled myself out of him only to thrust back inside. I quickly picked the pace back up, thrusting into him almost relentlessly, my precum leaking out inside of him.
Shadow's still tense body managed to level up the pleasure I felt with the extra tightness. I groaned as it was a little difficult to thrust into him, but a good kind of difficult.
"Oh man! Has anyone ever told you how tight you are? You feel great." I complimented him, to which Shadow could only respond with an faint embarrassed blush. Obviously no one had told him how great he felt on one's dick before.
"So, so big." The words slipped past him before he even realised it.
"So I've been told." I smirked at his statement, slamming myself inside of him extra hard to back his statement up.
Oh man, this was so much fun. I can't believe I haven't thought of doing this with him before.
I have been feeling something build up inside of me for a long while now, but only now was it reaching its boiling point.
"Where do you want me to cum?" I asked. I would love to cum inside, but I had to consider Shadow's feelings about the matter. If he didn't want it inside, I can't force him to take my load.
"...Inside... I... I want you to cum inside..." The answer was quiet and almost inaudible. It was obvious he felt embarrassed to admit it.
"Okay, if you don't mind." I panted as I continued to thrust and work myself to my climax. I closed my eyes and let myself enjoy the clenched, moist and hot embrace Shadow had on my shaft and just let myself go.
I came not shortly after, pushing my manhood inside as deep as it could go and came. Just like him, I felt pleasure wash over every inch of my body as my cum shot into him, coating the walls of his womb and filling him to the brim with this white, sticky liquid.
"Oh, Sonic." The ebony hedgehog in front of me whispered my name as one of his hands came to rest on mine. Without a doubt he felt the strange feeling of being cummed in for the very first time.
I let him go and let my soft member slip out of him. Shadow sighed in somewhat of a relief as he could finally lie down and rest his head on the pillow. I sat back and noticed with a smirk that a little bit of my cum was dribbling out of his used vagina. What better way was there to proof that I had just taken the Ultimate Lifeform?
But that just begs the question, though.
Just how fertile did the old Professor Gerald make his creation?
"Can we go again?" I could hear Shadow ask as he looked at me from his position on the bed, we had just barely caught our breath and already he wanted a second round.
Well, guess I was going to find out for myself just how ultimate Gerald's creation was on procreating.
