MERDER :)

Teamwork

It had been 5 months since Meredith chose Derek over Finn.
Finn still wanted Meredith, no he needed her.

It was 10pm and Derek had just gotten home from work, he was so horny he just wanted to fuck his wife in every position he could. He pulled into the driveway and saw her through the window cooking dinner, she was dancing.
God she looked so hot he thought. He went in the door and smelled pasta, his favorite.
He walked over to his wife and put his hands on her hips slowly moving them down until he was grabbing her ass.
"Someone's hungry huh?" She asked
"Very" he replied with a smirk.
"Babe, I'm cooking"
"Dinner can't wait" he said and he turned her around to face him.
She was staring into his lusty eyes eyeing his hard member. God damn it she thought, he's irresistible. They attacked each other's lips. Derek felt Meredith swipe her tongue across his bottom lip, a way of asking him to open his mouth. He wanted to tease her so he kept it shut. She pulled away and looked him up and down, now wet.
"Open your mouth"
Derek stood there surprised.
"I said open your mouth"
He opened it slowly and watched as his wife leaned closer into him and pushed him against the counter.
She put his mouth on his and her warm tongue entered his mouth. God it felt amazing. Soon they're tongues were fighting for dominance. Meredith grinded up against him and he lifted her onto the counter by grabbing her ass. They both pulled away for air, and she stared into his eyes.
"You want to fuck me huh baby" she asked with  doe eyes.
"Yes" he replied not knowing how to respond but agreeing.
"You need to beg for it"
"What?" He asked confused
She lifted up his chin not more than a centimeter from his lips as she whispered
"Beg me for it"
He had never seen this side of her. Being dominant, but god it was hot as fuck.
"Please baby" he asked
"Try harder" she responded
"Baby I need you, please let me fuck you"
"Better" she responded as she pulled him closer kissing his lips, slowly and sensually.
God he needed her. Right now.
He played with the hem of her shirt before lifting it up over her head. She was wearing a black lace bra to his surprise. She wanted this just as much as he did.
He pulled down the straps of her bra before reaching around her back and unclasping it. He started playing her with nipples, sucking one while toying with the other between his fingers.

Finn needed to talk to Meredith, he drove up to her house and saw the lights were on. He knocked on the door but no response, as he was about to leave he heart a distant
"Yes-"
He knocked again but no answer, he turned the doorknob figuring she was just on the phone and hadn't heard him. He walked in, and turned into the kitchen.
He saw Meredith on the counter with her top off and her head thrown back and Derek kissing down her cleavage.
A part of him wanted to run away, but the other part of him wanted to stay there and watch. He stood there for a few minutes watching his previous rival pleasure the love of his life. This was so hot. He felt his pants tighten. He cleared his throat, and Meredith and Derek turned around to face him. Meredith was topless but didn't bother covering up. She found it kinda sexy that Finn was watching them.
Derek on the other hand tried covering her.
Meredith hopped off the counter and walked over to Finn, she looked down and saw his erection. God he was big.
Finn was trying not to stare at her breasts, but he couldn't resist. She must've noticed him doing this but she started playing with the buttons on his shirt.
"I-I didn't mean to barge in I was just uhh-" he tried finishing his sentence but it was impossible with Meredith topless slowly taking off his shirt.
"Don't worry about it baby, we were just getting started"
Derek looked at his wife flirting with her ex as he was still hard, and still wanted more.
"Baby" she started as she turned around to face her husband.
"You don't mind if Finn here joins us do you?"
Finn stared at him, he was now shirtless too, he was clearly horny now. I mean who couldn't be with his wife like that.
"I guess not" he responded, he wanted to show Finn that Meredith had chosen right the first time. That he was going to make her feel so much better than Finn could.
Meredith pulled Finn over to Derek and continued to make out with her husband as Finn watched. The bulge in Finns pants became more prominent. He watched as she rubbed Derek's erection through his pants. Derek was groaning as she rubbed up against him.
She pulled away from Derek and started to kiss Finn. God she felt so soft. Finn slowly grazed his hands over her perfect back and moved his hands on her breasts.
Derek was watching and getting jealous; no one should be able to touch his wife like that other than him.
Finn was squeezing her boobs now. Meredith was letting out heavy breaths as her ex touched her body. Their tongues were colliding with each other. Meriden pulled away and slowly started walking up the stairs. She was pulling down her yoga pants as she went up. Now only in her matching black thong. Finn and Derek looked at each other both hard for the same women. They pushed each other over and ran up the stairs. They saw the bedroom door closed and opened it at the same time, to see Meredith naked and sprawled out on the bed, playing with herself. She let out small throaty moans.
"Help me" she whimpered still rubbing herself.
Derek walked over and pulled her hand away replacing it with his own.
Finn took off his pants now only in his boxers and later on the bed with Meredith and started making out with her. She took her hand and started rubbing him through his boxers. She played with his waistband as Derek was still rubbing her clit.
She was moaning a little louder now, feeling her orgasm creep in. She was jerking Finn off now as he moaned. Derek then thrusted two fingers in with no warning and started pounded them into her tight center. Meredith screamed in pleasure. Both of the boys knew she was close. Finn pulled away to watch her orgasm.
"Fuck- ugh- fuck don't stop, oh my god" she screamed.
This caused Derek to go even faster. He eyed Finn and then looked at the drawer telling Finn to open it. Finn did as he was told and opened the drawer seeing a pink vibrator. He grabbed it and placed it on her clit knowing this would make her orgasm 10x better. She jolted in surprise as Derek kept thrusting his fingers in her holding her hips down.
"Fuck-fuck-fuck, oh my god I'm- I'm gonna cum"
"Cum for me baby" Finn said.
This was usually Derek's line but he didn't mind this time.
She released all over Derek's fingers as she panted.
He took them out and put them in Meredith's mouth as she sucked on his fingers. He pulled them out and started taking off his pants.
Finn put the vibrator on the bedside desk.
"Do you want Finn to fuck you baby? Is that what you want" Derek asked
She nodded waiting in anticipation, Finn and Meredith had only ever kissed they've never done anything more.
Derek looked at Finn and singled him to fuck her.
Finn took off his boxers and positioned himself at her entrance he rubbed his member up and down her wet folds. She tried moving towards him so he would just fuck her already.
He stopped "uh uh baby you gotta be patient, now you get a punishment"
"Derek will you grab the vibrator for me please" Finn asked
Derek grabbed it and handed it to him.
Finn put the vibrator on her clit as she jerked from the pleasure. Derek went up to her and started kissing down her cleavage, he was curling his fingers around her neck as he sucked her nipples.
She was moaning from all the pleasure.
"Oh fuck, I'm gonna cum again" she moaned
Finn turned off the vibrator right before she could finish and Derek pulled away.
"See? Punishment" Finn said.
Then he thrusted inside Meredith without any warning, going hard and fast.
Derek started watching Finn pound into his wife as his wife was moaning his name.
He started rubbing himself up and down his member. This was so hot.
"Mmm" Finn groaned.
He felt Merediths walls contract around him and he knew she was close. Then he decided to do the unthinkable. He put two fingers in her along with his dick. Her eyes shot open as she screamed.
"Fuck oh fuck" she screamed
Derek started pumping himself faster, he was so close.
They all three came at the same time.
Finn pulled out of her and moved to the other side of the bed, letting Derek have his turn.
Derek knew Finn made her feel good, but he also knew he could make her feel better.
Meredith had her post-orgasm glow on her, as she was sweating; coming down from her high.
"Hi baby" Derek said
"Mm" was all Meredith could get out
"Did Finn fuck you so good baby?" He asked
"Mmhmm" she moaned
Derek laid on top of her and the two started making out again. Derek flipped them over and Meredith was on top. Derek leaned up to her ear and whispered so Finn couldn't hear him
"I'm going to make you feel so good baby, now ride my dick like a good girl"
She moaned at his words.
She started grinding back and fourth with him inside of her.
Soon enough she was bouncing up and down
Derek loved the sight of his wife riding his dick.
Her perfect body on top of his.
Her boobs bouncing up and down.
He was in love with her.
She was close again, her walls were contracting around Derek's dick.
Suddenly he flipped them over and started pounding into her as fast as he could, sweat dripping down his forehead.  He knew she was about to cum again. He leaned down to her ear and whispered
"You don't get to cum until I say you can understand?" He asked
"God this pussy is so good" he moaned
She couldn't hold it in much longer.

Finn was watching Derek absolutely destroy her pussy as he was jerking off. He spilled his seed all over the bed as he groaned looking at Meredith.
Meredith made eye contact with him as she looked at his dick and bit her lip before closing her eyes and rolling her head back.
She was squirming, she couldn't hold on much longer.
She knew what she needed to do. Something that drove Derek insane.
"Daddy ugh- daddy can I please cum?"
Derek looked at her, his beautiful wife, completely under his control.
"Yes baby, cum for me"
She released around him, and he pumped faster as he came too.
"Ugh fuck" he moaned as he slapped her pussy.
"You did such a good job baby"
She sat up and leaned him down as she made out with him.
"Your so good at making me feel good baby"
They stopped and looked over at Finn, soft now.
Finn knew this was a one time thing and showed himself out as he grinned. He didn't need much more than this. Closure.
Derek kissed Meredith slowly this time as they laid down under the sheets, still naked. The kissed for a few minutes and then Meredith turned around exhausted. Derek spooned his beautiful wife.
"Goodnight baby" she said dozing off
"Goodnight sweetheart" Derek replied squeezing her more
"And just so you know, I chose right" Merideth whispered before falling asleep.
