Lockjaw

Summary:

You decide to give Steven some 'help' with something of his... The both of you are flustered about it, and like it somewhat, but you're both denying it like the plauge.

Notes:

GUYS, THIS IS MY FIRST SMUTFIC IN A WHILE, I HADN'T WRITTEN ANY SINCE LAST YEAR I THINK, PLEASE DON'T JUMP ME BEHIND THE 7/11-

"Just... Fcuk's sake. Just make this quick. Nobody needs to know about this."

Steven blushes as he presents himself to you, motioning you to just do whatever it was you were about to do. Your hand reaches over to feel Steven down, fingers caressing to feel what could only be described as a tendril of darkness, thick, and throbbing with need and desire. It was odd, yet it sent a rush throughout your entire body. Nothing you've felt had ever felt like this before. So raw, yet so mysterious. His cock wrigles a bit in your hand, not something that most regular phallic things do. If anything, Steven's cock was more close to that of a tentacle rather than human anatomy. Oh, well, there was always a first time for everything!

You start to run your hand up and down, the manner slow and monotonous. A low groan is aroused from Steven, heat rising to his face. It's been a while since he had been touched like this from someone else. Radiant warmth from your hand roving over his shaft, it made his heart thud in his chest. He held back most of the sounds, keeping his lips sealed. Damn, he really didn't want to let you know how badly he was growing to enjoy this. Despite how collected he was verbally, aside from the moans, his body language is screaming, the pleasure was blatant. He was loving it.

As you kept rubbing your hand over the mass of his writhing manhood, you grew curious. Not yet. You had to time this perfectly, since this was a manner of pleasure. But then again, Steven said to make it quick. Well, you were one to satisfy and satiate. Even if it was for a quickie like this. With little to no warning, your tongue flicks out to lick at the tip of his cock, the taste of something vauge lands upon your tastebuds, mixed with the salt of his precum. For the life of you, you couldn't tell what Steven tasted like. It felt charred, yet cool, with an underlying tone of something bitter. Not bad, but not something you would taste on the regular.

Licking further, your tongue travels all over his shaft, feeling it writhe around you, muscle on what could presumably be muscle, or whatever it was that Steven had. Eventually, you allow your lips to encase around the tip of his tentacle-like cock, really getting a taste as you start to bob your head, taking him in inch by inch, methodical and slow, yet just fast enough to coerce a few moans. God, you could feel him wiggling about in your throat, his cock stretching and swirling in your mouth. It felt so damn good... You had to hold back a moan, not wanting to give away that you enjoyed the feeling of a tentacle dick thrashing about in your mouth.

"Mgh... Fkcu, you're enjoying this, huh? S-Slut..."

A scowl forms on your face as you pull your lips away, replacing it with the motion of your hand, fingers deft around his apendage that throbbed and thrashed, begging for your tender, soft lips once more. "Shut up-"

Before you could utter anything else, Steven holds the back of your head, pressing his cock into the warm cavern of your mouth. He moves your head along the length, a shocked groan leaving your lips. Really? He was manhandling you after he told you to make it quick? Well, you certainly weren't complaining. As you continued to suck down on his manhood, feeling each inch coat your tongue, you could feel his hand stop. Odd... It was getting so good. Then, you feel it.

With minimal warning, Steven starts thrusting into your throat at a moderate pace, the feeling of his cock lugging within your mouth, in and out, contorting from pleasure. Audibly, you gasp. So now he was fucking your face, too? This was unexpected, yet so arousing! You've never expected to give someone with a tentacle dick a blowjob, but it feels oddly good. Kind of like if calamari and felatio porn mish-mashed together. No? Maybe? This was a first-hand experience that you couldn't really compare to anything! And that newfound excitement was making a warmth form within your nether regions.

One hand trails off from Steven's hip, down to your own body. Shame didn't come to you as it did to Steven: if someone walked in on you jerking off while sucking him like a vaccum on some hard wood floor, they're more than welcome to watch. You quickly undo your pants just enough to slip your hand beneath your clothes, so your hand glides towards your utmost sensual spot, and you start rubbing yourself out. Moans vibrate against Steven's manhood, causing pleasure for you both as he goes faster, the tip of his tentacle cock hitting the back of your throat.

Choking on it was one thing, but this was a new level. Steven would deliberitely retract his cock, only to have it shoot out to the very end limit of your throat, articulating it in ways a regular dick couldn't even imagine to do so. It rubs around in your mouth, throat, coating your mouth in his taste. His favorite thing to do was to hit the tip rapidly against the back of your throat, the sound of your gagged moans reverberate off the alley walls. The hand that was fumbling with your junk speeds up, desperate, as you felt the need for release loom over you.

His cock would end up going back and forth in a manner of speed you were unaware was possible. Tears flow in your eyes from how much you were beginning to gag, and you can feel Steven's cock start to stiffen up like rock, rather than being mobile and tentacle-like in behavior like it was beforehand. Was he close to cumming? Well, you were close, too. It'd be oddly romantic if you both came at the same time. A snicker escapes Steven's lips, "Wow, h-how perverted! Mmhg... Tou- Touching yourself while s-sucking my cock? Hah... Mmh... You really are a fkcui-ing lsut, huh?" A sneer, followed by him speeding up, "Fcuk, fcuk! I'm close, I'm gonna cmu, don't- don't stop, tlus... Ngh! You'd better swall- swallow every last drop..."

Salty, hot strings of cum escapade down your throat, and you swallow every last drop. Not only is it salty, but there's a vauge taste to it, dark and musky, not something fully comprehensible. Steven keeps your head shoved against his cock, a couplet of loud moans vacating from him. You came at the same time, slick ejaculate pulsating out of your lower region, some onto your underpants that were still clad over your aching need, and some on your hand that had been stroking yourself. Wiping your hand on the pant of your leg, you rebutton your pants, the last droplet of cum entering your throat.

Steven releases your hair, allowing you to pull off his waivering tentacle cock, breathless. The apendage retracts into his shadowy form. Silence washes over you, aside from occasional panting. Both of you just had sex in an area that was somewhat public, yet neither of you got caught. Huh. It either was really lucky, or it must have been really late. One of the two. Whatever. A heat of rising inferrno hits your face, as you realize that, yeah, you might have liked feeling his tentacle dick, and you might have wondered what other holes he could stick himself in that could get you as aroused as tonight.

An awkward hit of silence still wafts in the air between you, interrupted by Steven letting out a cough, clearing his throat. "So, uhhh... You- You wanna do this again some time, dude?" He rubs the back of his head, the secondary face that was attached to his head blinking incredulously.

"Uhh, yeah. Yeah, I wouldn't mind it," You fumble about in your pocket, pulling out your phone and scrolling through it like nothing happened. The tension was thick in the air. After the moment you both had been intimate together, either of you were too abashed and chagrined to admit how truly arousing that moment was between you. Hell, the both of you were avoiding eye contact like the plauge, yet neither of you parted from your area in the alleyway.

No warning comes when you feel something cool against your hand, so you trail your eyes downward to investigate what it could be. A shadowy hand, brushing up against yours, coy, sheepish, Steven's. The inferno of blush worsens beneath your skin, as your eyes shoot up to look at him. It doesn't occur to Steven at first, but when he looks at you, you could see the embarrassment haunting his expression as he rips his hand away, rapid. He didn't seem to want you to think that he was too invested in it. Well, neither of you were too invested into it, both of you reciporocated well, even if Steven called you a slut.

"Cool. Cool, cool, cool," Awkward, quick, just like how Steven was when he pulled his hand away. Silence once again fills the alley, but different this time. You mull over the actions of the night, and presumably, so does Steven, An inept, yet genuine smile forms on your face, the one way to say you had a great time without picking some ill-chosen speech. Steven reciporocates the smile, as you both simply enjoy the other's company.
