#ryusui

YOU WERE IN A STICKY SITUATION... literally. 

Why did your best friend have to walk in on your drunken hookup with his other best friend? And why did he want to join in?

Well, knowing Ryusui it was to be expected. 

If you were being honest, you knew this would happen eventually. Heck, deep down you wanted this to happen. It’d been a small fantasy of yours to have a threesome with him and surprisingly your filthy dreams were about to become reality.

After you and Senku were caught by the blonde, things had progressed… The moment you’d all finished talking things out, both their hands were on you, exploring and squeezing and grabbing at your clothes.

“Do you even know what to do with all that?” Ryusui smirked at Senku before pulling your back flush against his front, placing his hands on either side of your ribcage and sliding downward until he reached your pants. He popped the button and unzipped them, dexterous fingers slipping beneath your panties and finding your clit with perfect precision, rubbing in tight circles. 

“Nng—!” You gasped. Then Senku grabbed the hem of your top and pulled it off, exposing your bra.

“Of course I do. We were literally hooking up before you decided to interrupt.” He hastily slipped the straps off of your shoulders, dipping his head down to nuzzle the warm skin of your neck. His tongue swiped against it, followed by a soft bite. The cups of your bra were pulled down, an intense sensation shooting through you as Senku gently pinched your nipples and rolled them around between his fingers.

Your head was swimming, more from the situation than from the drinks you had hours ago. Their scents combined was a heady aphrodisiac, designer cologne and the fragrance of leather mingled together. 

Senku backed away slightly, and quite suddenly was on his knees before you. He curled his fingers into the waistband of your pants and pulled them down along with your panties over your hips, fabric pooling around your ankles. 

“Hah! You should be thanking me, I know she will since I saved her from a boring fuck.” Ryusui slid his fingertips over your clit in one last circle before gliding over the slick skin, forming a V with his fingers and parting your lower lips right in front of Senku’s face. He didn’t need to be told twice, diving in hungrily. His tongue pressed between your folds, licking a trail up through them towards your clit. He licked with the flat of his tongue, not as precise as Ryusui’s fingers had been but the velvet muscle sliding over your bundle of nerves felt just as heavenly.

“Ah!” A shaky whimper escaped your lips before you realized it, causing you to grip Ryusui’s forearms and dig your nails in. He sucked a breath in through his teeth, you realized just how close to your ear he was and how uncomfortable this position was. “W-wait, pause!”

Both men backed off immediately, eyes burning into you.

“I’d rather do this on the bed.”

“Of course you do, picky girl.” Ryusui chuckled behind you, turned you by the hips to face him and picked you up, carelessly placing you on the mattress. As both of them hurry to pull their own clothes off you unclipped your bra and tossed it into the darkness, not caring at all where it landed. When you looked up Ryusui was at the side of the bed, he looked beautiful in the moonlight. Shimmering brown eyes sized you up like a well earned meal before grabbing your ankles and pulling your ass to the edge of the mattress, something hot and fleshy and hard fell against your slit, sliding back and forth in your wetness.

“Ryu, quit being a damn tease,” you groaned, grinding your hips into his, aching to be full of him.

His lips curved into his usual cocky smirk and despite your whining he continued sliding his cock through your folds, coating his pink tip with your juices. “Who else is gonna tease the hell out of you, have you squirming underneath them? It sure isn’t Senku, since he won’t last a minute near you.”

The mattress dipped behind you, and soon Senku was kneeling by your head. “Well, it’s been more than a  minute and I haven’t exploded. Looks like you were wrong, ” he barked at Ryusui, a hand gently running through your hair.

“Some advice from someone who can satisfy her. It takes wayy more than a minute to make her cum, let’s see if you last that long.”

“If you could satisfy her, she wouldn’t have been hooking up with me. So what’s your point?”

“Umm, I’m right here? Please don’t start fighting over me again, it turns me on and I’d rather cum from some action rather than petty words.” You sighed, finding their arguing arousing, who wouldn’t want two guys fighting over them? 

“Then we’ll stop, can’t have you melting yet!” Ryusui laughed, winking at you making you roll your eyes.

Then you looked up, instantly captivated by the stiff cock standing before your eyes. It’s a good size, with a delicious curve to it, not as long or as girthy as Ryusui’s but it still looked tasty. Who knew the nerd would be packing? “Yum,” you licked your lips, fuck now Senku knew how lustful you really are.

Seeing how your tongue darted out of your lips so sensually, a thick blush spread across the scientists face as he imagined how those lips would feel around him. “P-please—”

“Since you’re begging… Don’t mind if I do,” you reached to take him in your hand, relishing the sigh he gives you when you squeeze it gently.

“Focus on me, or I’ll make you.”

That’s the only warning you got before Ryusui rocked his hips back and slammed them forward, filling you in one efficient motion. You yelped in surprise, a sound one step down from a shriek. You were wet enough that the sudden intrusion didn’t hurt. The cocky laugh you heard after was completely ignored. The only thing you could focus on was the stretch and pressure of him already fucking you steadily, and the feeling of his hands grabbing your hips in order to pull you back every time his thrusts push you away. 

“Oh shit,” you gasped, trying your best to get your head back in the game so you could appreciate the cock in your hand. As soon as the initial shock of pleasure eased, you looked back up at Senku, who looked from the scene at the edge of the bed back to your face. 

He groaned at how perfect your hand looked wrapped around his cock, and traced the shape of your jaw until his thumb settled on your chin. He applied tender pressure, and you took the hint and opened your mouth, licking up the underside of his cock. A generous dribble of precum had leaked from his tip, you lapped it up with your tongue before taking the head into your mouth. Senku groaned your name, fought the urge to shove his hips forward and fuck your pretty mouth.

Your body being jostled and the feeling of Ryusui’s cock pushing and dragging on your walls made it difficult to truly suck on Senku, so you settled for short bobs of your head peppered in with kisses and licks to the tip. 

“Don’t get too worked up,” Ryusui huffed as he addressed Senku, “or you’ll just disappoint her.”

“Are you seriously telling me how to fuck her, is she your girl or something?” 

“Are.. you.. my.. girl?” Ryusui panted, thrusting into your gummy walls with every single word.

“Fuck no- fuuuckk, please shut up!” You mewled and squeezed around him making him hiss at the sudden tightness.

Senku chuckled at this before his breath got caught in his throat from the sensation of you stroking him at a faster pace. “Looks like she’s not yours.”

“I know that, she’s not anyone’s. It’s like…” Ryusui steadied his pace, “like this whole thing. We’re not really into monogamy.”

“Now your whole freaky friendship makes sense,” Senku stammered, then suddenly your hands were off him and you let out a frustrated sigh.

“Oh my days, just shut up and kiss already,” this was the weirdest way for Senku to find out about the situation between you and Ryusui. 

Both men looked at you, stunned, and then looked at each other. You heard a frustrated growl, but you weren’t sure which of them it actually came from, probably Ryusui since the greedy fuck wanted Senku just as much as you did. 

It happened quickly, Ryusui grabbing the other man by his hair and both of them leaning in to mash their lips together in an angry kiss that was more teeth than tongue. Despite everything, he never stopped pounding into you, and between the sensation and the erotic display above you… it all had you drooling. 

The kiss broke, and they both focused their energy back on you. Senku had adjusted to lay beside you, groping your chest and teasing your nipples all while kissing and nibbling just beneath your ear. Ryusui adjusted his grip, pushing on the backs of your knees and fucking you with feral ferocity. 

Senku changed his tactics, hand dragging down your belly to play with your clit. The scientist knew a lot about anatomy and was gonna show you just how well versed he was on the subject. He kissed across your jaw, towards your mouth, and ran his tongue over your lower lip. On instinct, you opened your mouth and let him lick inside, and suddenly every tiny noise you made was loud and clear. 

“That’s it,” Ryusui hissed, “we want to hear you.”

Your core began trembling, being their center of attention was quickly becoming too much. You whimpered, managing to speak through the kiss. “M’really close, please!”

At that, Senku worked your nerves harder, stirring spirals of delirious pressure over your slickened flesh. The thread of your willpower broke, orgasm coming onto you as a slow but every intensifying burn. “Nng, I’m coming- ah!”

Ryusui’s hips snapped against you and you cried out, soft and raspy at first but becoming louder with every spasm of your pleasure. A short squealing scream burst from you at the height of it all, earning a triumphant but labored laugh from the man fucking you. Just as it died down, Ryusui quickly let go of one of your legs and pulled out, jerking his cock only a few times before spilling himself over your stomach in ropes and droplets.

There was a brief pause, where the only sound was your mingled labored breathing. 

“Your turn, Senku.” Ryusui slipped his hands beneath your ass and lifted, pushing you further towards the center of the bed. 

Senku dipped his head down to kiss you briefly before sitting back on his thighs, adjusting you until you were settled in front of him on your knees with your ass in the air. The cum on your abdomen rolled upward, dripped down onto the sheets. Your head was turned to the side with your cheek pressed against the mattress. 

The spongy head of his cock caught on your opening. His voice was raspy when he said your name in a low tone. “Are you ready?”

Still a bit dazed from your orgasm, you nodded. “Mhm.”

He pushed his way inside of you. Slower than Ryusui had, but brusquely enough that you yelped involuntarily. In seconds he was deep inside you, balls nestled against your cunt. Senku groaned, savored the moment, and promptly began thrusting into you.

Immediately you were clawing at the sheets. Your fucked-out pussy was still pulsating from your orgasm, hyper-sensitive and every single nerve ending sung out in your head. Your pleasure had been tapering off, but with Senku’s shaft rubbing insistently on your front wall it was quickly building back up again. Your mouth hung open, and every thrust pushed a breathy whine out of you. 

The mattress dipped again and you felt your hair being tucked behind your ear. You looked up at Ryusui above you, but you weren’t quite able to focus.

“Pull her up to your chest.”

There was a moment of hesitation, but Senku leaned down and crossed his arms under your ribs and pulled. The motion lifted your upper body, arched your back as he kept up the pace of penetrating you. Ryusui sat before you, so you reached out to steady yourself with his shoulders. He spoke in a sultry tone.

“Look at you, having one right after the other. I hope we haven’t tired you out.”

You moaned and swallowed before shaking your head. “Nah, I’m good.” Senku fucked you harder. “Ah! So good, both of you feel so fucking good.”

Ryusui hummed, long arm reaching beneath you. Once again, your bundle of nerves was treated with skill. He leaned forward and licked into your mouth, the tip of his tongue tracing around the edge of yours before flicking over the roof of your mouth. You sobbed with pleasure into the kiss and held on for dear life as the duo rubbed and fucked you without remorse.

The overstimulation was nearly too much, bouncing back on Senku’s cock while Ryusui’s adept fingers pushed and pulled and rubbed on your poor little clit perfectly. One of Senku’s hands wandered from your ribcage upward, and as soon as he pinched your nipple you broke. The second orgasm hit you with ruthless force, you shrieked with the intense burst of feeling. It was short, followed by your ravaged moaning as you clenched down hard on his length. The silky heat squeezing Senku’s cock pushed him dangerously close to cumming inside, but he did his best to hold out as you threw yourself back on him to get the most stimulation you possibly could.

The very moment your inner twitching stopped he ripped himself out of you, cumming hot on your delicate thighs as he drug his dick through them.

Senku panted, and they both held you securely in place long enough for both you and him to regain your senses.

It occurred to you then exactly how much of a mess you were. Semen adorned your body from your navel all the way down between your thighs. Slowly you sunk from their grip to sit on the sheets, and rubbed a hand over your fucked out face.

“I’m so damn sticky.”

“Looks like you love it,” Senku smirked.

Ryusui leaned closer to you with a dark grin, “this was amazing, who wouldn’t love it? Also, how was our first threesome?”

“Perfect,” you smiled before giving him a peck, “been wanting to do this for a while, but I didn’t think it’d be this messy.”

“If someone were to walk in on us, I’d say it’s a sticky situation,” Ryusui’s cheesy joke earned a loud snort from you and a playful eye roll from Senku.

A sticky situation it was, but it was the best situation to be in too. For all of you.
