Two Mates Are Better Than One - Sterek x Reader

Pairing: Sterek x Reader

Prompt: my love for Sterek and Dylan O’Brien’s hands.

Warning: Smut! A lot of heavy straight, gay and bisexual three ways it had to happen okay it just did. Also light d/s undertones. Not a lot barely noticeable if you blink.

Description: As Derek’s mate you knew he loved you but another part of him was always somewhere else so when you decidedly crash his pack reunion and you discover no one knows about you, you may or may not tell a certain lanky young man about Derek’s secret love for him. But who could blame you. Two mates are better than one…

A huge thank you to my beta @lets-imagine-fanfics, who as always is a pro at deciphering my terrible spelling and grammatical errors.

ENJOY!!!!

***************

You strut up the stairs with anger boiling under your skin. Everything that had happened over the last few months was unreal, but the fact that the only person you had left decided to say he was going to be a few weeks and then not come back for 3 months.

You dug your high heel in the pavement as you flicked the door open with ease before strolling into the apparently full loft that Derek had told you about when you were in New Orleans together. You ignored the looks from the people you didn’t know but vaguely recognised, walking straight into the middle of the pack.

“Stiles, did you eat my last pudd-”

SLAP!

Your hand connected with Derek’s cheek before he even scented your presence. His eyes shot up in surprise, and the second he saw you, he panicked, and you could see it in his eyes even if everyone else couldn’t. Good, he should panic, you thought angrily.

“Y-Y/N…baby…” Derek started and you let out a growl in return.

“Don’t you dare! ‘I’ll be 3 weeks tops.’ That’s what you told me Derek!” You screamed angrily before grabbing his arm and throwing him straight over your shoulder onto the cold hard ground of his loft.

“Maybe I should find a different mate!? One worthy of me!” You snarled angrily as you glanced around the pack that he’d told you about and showed you pictures of.

“Stiles! He seems fun!” You smirk as Derek growled as he tried to stand up but your pushed your heels into his chest.

“Ah ah ah. Anything you wanna say first, DerBear?” You asked with fake sweetness.

“I’m sorry, baby. I was gonna come get you when I settled down…” He huffed sadly, giving you his best puppy eyes and you melted instantly.

“Holy shit, someone tamed sourwolf!” Stiles laughed as he pointed at Derek on the floor and you shot the younger boy a smirk.

“You wanna end up under my heel too?” You asked mischievously.

“Depends on why it’s there.” Stiles answered instantly and Derek shot up, instantly wrapping a possessive arm around you.

“I like him. I can see why he’s your favourite.” You stated with a giggle as Derek flushed.

“Awww, I’m your favourite!? I thought I was your least favourite.” Stiles preened happily as Scott rolled his eyes.

“Wow, does anyone in this pack know who you are?” You asked as your eyes flickered from Stiles to Derek. With a sigh you decided to withhold what you knew since clearly he wasn’t very open with his pack.

“Anyways, I’m Y/N. Derek’s girlfriend.” You informed people and they nodded as they greeted you.

“I’m guessing no one knew I existed?” You asked with a laugh and everyone nodded.

After getting to know the pack, who left at about 11pm, now you were sat looking at Derek with a serious gaze. He knew what you were about to bring up, but he didn’t want to hear it although he knew that wasn’t going to stop you, because it’s something that needs to be addressed.

“Does anyone even know why you left? Does he know?” You sighed with a frown.

“No…” He whispered sadly and you stood up angrily.

“Der, you can’t keep doing this…you obviously love him!” You shouted at him as you stood up and began pacing.

“And I love you!” Derek replied equally as angry.

“I know that, Der! I’m not saying I’m leaving you, calm down! I’m just saying, you need to tell him!” You huffed and he looked beyond confused.

“Why…I’m with you?” He scoffed in confusion.

“You wouldn’t be the first born wolf to take two mates. There are a lot of gay wolves that also need to carry on bloodlines…” You supplied and his eyes widened like he couldn’t believe what he was hearing.

“Y-You’re not serious?” Derek stuttered with a bright red face.

“Actually I am. I love you Der and I want this for us. Ooo someone’s here…” You whispered as you turned towards the spiral staircase.

“Go talk to him.” You whispered pushing him down the stairs.

You stood by the stairs and listened to the conversation from there, tuning your ears in as Stiles took a deep breath. You should be jealous but honestly your were excited, you may not feel that way about Stiles but maybe you would one day. Right now you were just happy Derek Hale is getting everything he wants and deserves.

“I-I know this is weird, but was your girlfriend telling the truth earlier am I really you favourite?” Stiles whispered nervously.

“Yeah…” Derek grumbled huskily as his heart raced in his chest.

“You’re girlfriends seems cool…”He muttered lamely ad you rolled your eyes at how constipated they both seemed.

You had enough and started down the stairs startling Stiles at the sound of your heels. Derek looked up, meeting your eyes with a scared look and you gave him a reassuring smile before beginning to circle Stiles, before settling behind him, your hands on Stiles shoulders.

You felt the boy tense under your touch as you felt shame roll off him in waves making you smile softly. He feels bad because he was attracted to your boyfriend and you thought it was the cutest thing you’d ever seen.

“Don’t worry Stiles. I don’t mind that you find him attractive.” You whispered in his ear making his body shake slightly.

“Shall I tell you a secret?” You asked and Stiles surprisingly found himself nodding.

“Derek finds you attractive too.” You purred as you looked at Derek from behind Stiles.

You crooked your finger towards Derek, beckoning him closer, making him walk towards you and Stiles with a flushed face as he kept quiet. You giggled against Stiles ear before licking the shell of his ear, while maintaining eye contact with Derek. You couldn’t tell if he was more jealous about you touching someone else or that you got to touch Stiles first.

“Look he doesn’t know who to be more jealous of…isn’t it cute? Do you know how many times he moaned your name in his sleep? He told me about you…how he had to leave because he couldn’t be around the love of his life while they screwed his cousin…” You teased you know it was a little cruel but you needed to let him know you weren’t happy that Derek had suffered.

“L-Love of his life?” Stiles stuttered with wide eyes and you gripped his face turning him to you.

“Did you know sometimes wolves have more than one mate?” You asked as you stared into his eyes.

“Y-Yes, when a wolf is in need of a cub but prefers the same sex, they usually take on another mate to breed with…but I can’t breed so I’m kind of a useless mistress.” He rambled, making Derek chuckle a little at his antics.

“You are so cute Stiles… I’m doing the carrying you’re doing the main mate position.” You whispered and he seemed even more so confused.

“I-I don’t want to push you to the side, t-that’s not fair… he’s your boyfriend.” Stiles whispered fearfully like this was all a trick.

“Oh, baby boy, this was my idea. Wasn’t it, DerBear?” You purred seductively as you look at your boyfriend you swiped your tongue across Stiles’ lower lip.

“O-Oh you wanna be a throuple?” Stiles asked realising what you were clearly getting at.

“Yes, but we are not calling it that.” You laughed as you turned Stiles to look at Derek.

“Show him Der…show him how much you want him…” You whispered as you pushed Stiles into Derek’s arms.

“Oh and Derek?” He looked up at you as he caught Stiles in his arms.

“Don’t be afraid to throw him about a little, I have a feeling he’ll like it. I know I will.” You said in a sing song voice as you started stripping your heels off and jeans, before shedding your bodysuit, leaving you in a black lacy matching bra and panties set.

“Is she serious, I can’t tell…” Stiles asked Derek as he clutched the male wolves v-neck.

“Yeah, she’s serious… So am I… I-I… I love you, Stiles. When you came and found me, and I found out you weren’t with Malia, I didn’t know what to do… that’s why I didn’t contact Y/N… she knew how I felt about you and I was ashamed of still being in love with you while I had a girlfriend…but she said she wanted to try us three together…Personally I’m starting to think she’s just a pervert and wants to watch us have sex.” Derek joked towards the end and Stiles couldn’t help his own chuckled.

“Well, I love you too, Der, and I’d like to try this but how about instead of watching, you join in Y/N? It would feel less creepy.” Stiles whispered shyly and you let out a delighted squeal as you skipped over to the two boys who were still in a sort of embrace.

“There’s nothing creepy about watching, I bet Derek likes to watch.” You whispered playfully, before pulling Stiles down for a kiss.

His lips were as soft as you expected them to be. Derek had spoken so much about the boy over the last year, that you feel like you could almost taste him on your tongue whenever Derek kissed you. It never bothered you, it only made you more curious to meet the younger male.

You moaned into the kiss as your tongue twisted around Stiles’, you could hear Derek panting as he watched the two people he loved kiss. You opened your eyes as you pulled away your eyes meeting Stiles’ amber ones, his lips glistening and swollen from the kiss… he was beautiful.

“I’m suddenly realising why you love him… he’s alluring… like an aphrodisiac… looks innocent but the second you’re hooked, you’re done.” You whispered with flushed cheeks as you looked at Derek with a satisfied smile.

“How many times have you fucked yourself open, thinking of Derek? Hmm?” You whispered against his lips.

“Too much…” Stiles moaned as your nails dragged down his clothed torso.

“See, I bet I can peg every one of your kinks too… I did with Derek, didn’t I, baby?” You giggled and Derek smirked at you, flashing his wolf eyes at you playfully.

“Praise kink, but sometimes you like being shamed instead.” You guessed making his breathing hitch in his chest.

“Oral fixation.” Derek groaned as his eyes met with Stiles.

“Ooo, cum slut?” You asked with humour in your tone, but when Stiles’ heart started racing, your eyes widened at the thought of this boy loving being covered in Derek’s or maybe even your cum was a turn on for whatever reason.

“Oh he is… you two are wearing too much.” You whined as you started peeling Stiles’ plaid shirt off of his shoulders as you watched Derek strip his v-neck.

“Isn’t he gorgeous, baby boy?” You purred into Stiles’ ear as you pulled his plain white t-shirt over his head and off of his body.

“F-Fuck… I must be dreaming…” Stiles whimpered as your nails dragged down his now bare chest.

“Oh no this is very real, Stiles. So do me a favour, look at me.” You asked sweetly making him look you in the eyes.

“I need to make sure you’re okay with this. I need your full consent and agreement to use traffic light system incase I go too far okay?” You muttered and he smiled honestly.

“Yeah I want this…” He nodded enthusiastically.

You nodded before shooting a smirk at him and he suddenly looked a little scared. Instead of anymore words you grabbed Stiles’ hair dragging him to his knees in front of Derek, you knelt next to the younger male with a smirk as you unzipped Derek’s Jeans, pulling him out of his pants. Stiles gasped next to you making you giggle, with a nod of agreement, at his shock.

“Fucking hell, Y/N…” Derek groaned as he looked anywhere but at Stiles on his knees.

“Look at him, Derek!” You snapped as Stiles finally wrapped his hands around Derek large shaft pumping him a few times with his large hands, that you just now noticed and you felt hot from imagining them inside you.

“Shit, his hand…” You whimpered and Derek smirked suddenly very smug by you getting hot a bothered.

Derek stared down at you both, with a dazed dark look, that made you clench your thighs in anticipation. Stiles started licking the tip slowly earning a deep groan from the male wolf. You bit you lip as you watched Stiles’ mouth finally wrap around the tip, it had to be the hottest thing you had ever seen.

Your hand drifted down your stomach straight into your panties as you watch Stiles’ head bob up and down, but the second you let out a moan of your own, both men’s eyes were on you. Derek looked down at you, with a filthy smirk on his face, before turning back to Stiles.

“Can you multi-task, baby?” Derek asked, his voice thick with lust.

“I think baby girl wants your fingers… she always did have a thing about hands.” Derek taunted as you drag your panties down your thighs and off of your legs before sitting next to Stiles with your legs spread.

“Shit, so wet…” Stiles muttered as his hand ran up your thigh.

“If you think that’s wet, wait until you see her cum.” Derek groaned, his hand guiding his dick back into Stiles’ mouth as the younger male happily let the older male thrust into it slowly.

“Fuck… you’re taking too long.” You mumbled in a needy way as you grabbed his hand and put it straight in you wet heat. Stiles moaned around Derek’s cock as he started easing a finger into you.

“Does that oral fixation only apply to dick, or…?” You moaned as you thrust against his finger. Stiles pulled away from Derek’s cock with a pop, never stopping his hand as he spoke.

“No, it applies to pussy as well.” Stiles smirked and Derek let out a dirty groan making you both look at him.

“Let’s go to the bedroom, we need lube.” You moaned even though you made no move to stop his finger as he started picking up his own pace.

“Baby, if you can’t get up and get to the bedroom, I’m gonna keep Stiles to myself.” Derek teased making you freeze. You quickly removed Stiles one finger and ran up the stairs and Derek picked Stiles up and carried him upstairs.

You jumped on the bed and waited as Derek brought Stiles closer to the bed. The older male placed him down, stripping him of his jeans and positioning Stiles on his back. You bit your lip in amusement as Stiles’ flushed under Derek’s forwardness.

You leaned over to the bedside table, grabbing the lube you knew Derek would have there and passed it to your boyfriend with a smirk. He took it happily as you sat next to Stiles again with a seductive smile directed down at him.

“Can I suck your dick, Stiles?” You asked with fake innocent and he started choking making Derek chuckle.

“Y-Yeah…” He stuttered with a blush spreading over his chest.

You knelt closer to Derek, who was opening the lube quietly. He’s been so quiet, not that he was usually different, but it was worrying you, so you leaned over and took his lips with yours making him sigh happily.

“Do you need some encouragement, DerBear. Want me to show you how its done?” You smirked as you took the lube from him, spreading a little on your index finger before bending over Stiles’ torso to feel for his entrance.

When you brushed over it Stiles gasped as you pushed past the ring slowly, feeling his entrance suck in your finger greedily and you let out a dirty moan as you looked up at Derek as he watched with dark eyes.

“So tight… and greedy.” You teased as you started thrusting the finger in and out of the younger boy.

However, before you could get too cocky, you felt two long fingers thrust inside of you, so fast you started shaking, your end right in sight already. You pulled your finger out of Stiles and passed Derek the lube as you took hold of Stiles rock hard member, engulfing it into your mouth almost instantly.

He gasped huskily,your name coming off your lips and it sounded like heaven, especially when it was followed by Derek’s name, as Derek pushed his much thicker finger past Stiles’ ring of muscle.

You moaned around the younger male’s cock as he continued thrusting his fingers, adding a 3rd one as he went. You took his member as far as you could, gagging a little as you almost took him all.

“Find her g-spot… she squirts… not lots, but it’s hot.” Derek groaned as he pushed another finger into the younger male, making him whimper, taking it happily.

Stiles nodded at Derek’s words and crook his finger in search of your special spot, the second you found it you popped off his cock letting out a dirt moan, his finger massage the special spot as his thumb came to caress your clit.

“F-Fuck… yes. Just like that! M’gunna cum, Stiles.” You panted breathlessly as you thrust against his fingers like a mad woman.

“Cum for Stiles, baby.” Derek groaned as he stroked his own hard on, never once stopping his stretching of Stiles.

“Fuck! Yes!” You cried out as you came all over Stiles’ finger, liquid leaking all over the bed making Stiles groaned at the sight.

“We’re doing that again later after you fuck me, big boy.” Stiles groaned as Derek circled the now 3 fingers inside of the younger male.

“Be a good girl and sit on Stiles’ cock, baby girl.” Derek commanded and you let Stiles slip his finger out as he watched with wide eyes.

“You ready, baby boy?” You moaned as Derek rest his chin on your shoulder, lining himself up at Stiles’ entrance as you hovered over his cock.

He nodded desperately and you slowly sat on his cock, moaning at the feeling of him inside you. He felt different to Derek, longer but not as thick as Dereks. It felt amazing, you looked over your shoulder at Derek to see his face pinch as if he was trying to control himself.

“Does he feel good, Der? Tight and hot?” You gasped as you angled yourself so Stiles was hitting your g-spot and you continued bouncing on him like he was your favourite ride.

“Y-Yes, you like him fucking your little pussy, baby girl?” Derek growled in pleasured as he stated slowly thrusting into Stiles making you younger boy almost scream in ecstasy.

“Y-Yes fuck! You’re so perfect, baby boy… Look at you, taking it all. It makes me wanna ruin you.” You whispered huskily, Stiles eyes meeting yours as his hands came up to grip your thighs.

“M’gonna c-cum… Y/N, D-Der, faster please…” His voice cracking as he moaned out loudly.

“Cum for us, baby boy.” You moaned and Derek sped up, grunt and growling as he left kisses along your neck, his hand cupping you breast as he pinched at your nipples.

“You too, baby girl, cum for us.” Derek whispered in your ear before moving his hand down to massage your clit.

You clenched around Stile, making him clench around Derek triggering everyone’s orgasms, the room filled with the smell of sex and the heat from your body’s entangled together.

“That was amazing…when can we go again?” You asked with a smile on your face and Derek started laughing as Stiles choked.

“Is she always like this?” Stiles asked exasperated.

“She’s a greedy girl, aren’t you, baby?” Derek chuckled darkly and you nodded your head with a cheeky smile on your face.

Derek lifted you off of Stiles, moving you to lay in the middle of both of them, before his hand drifted down to your cum covered sex. Derek started pumping his fingers into your special spot but what shocked you was Stiles’ fingers joined in like it was a normal occurrence, his mouth meeting yours in a heated kiss before you felt yourself building up again.

“Mmmm p-please…” You whispered as they both sped up.

“Moans so pretty for us doesn’t she, baby boy?” Derek groaned as he kisses Stiles in front you.

“Mhmm so pretty. Maybe we should try both of us together next time.” Stiles groaned and with the imagine of both men fucking you, you came over both males fingers.

“This…is totally…gonna work.” You said between breaths, making both males laugh at you.

Stiles brought up his hand seeing your cum all over it before bring it up to his lips and licking his fingers making you and Derek let out growls of satisfaction. You looked at Derek with a smirk before you both dived on top on Stiles clearly ready for round two. You couldn’t wait to see what the further held for you all.
