A/N: And that's it, one last chapter full of smut, everybody. Thank you for reading and thanks to Dimac.31 for reviewing the last chapter.


The next morning Erin was up before the boys and was finishing her breakfast when Dean stepped into the kitchen to get some coffee. He murmured a good morning to her and gave her a hesitant smile, but didn't join her at the table and hid in the library instead. Erin sighed in disappointment, but never made him talk, knowing she needed to stay patient.

The following week progressed much the same. Dean warmed up a little and stopped hiding from her, but the dynamic of their friendship had changed palpably. They weren't hanging out or laughing together like they used to, not spending more time than necessary in one room.

Dean was sweet and caring as always, calling her pet names, touching her and giving her warm smiles. But Erin noticed how he hesitated each time before he touched her and how careful he was about where to put his hands, something he had never even given thought to or been worried about before. As if he feared it could turn sexual in an instant.

His glances were brief, he was avoiding eye-contact, and Erin didn't see the same kind of desire he had shown towards her the night after the hunt.

Erin was scared that she had lost Dean as her friend for good, that it would never be the same between them. But she was determined to give him the space he obviously needed.

When he wouldn't come to her first, she took matters into her own hands and confronted him about the one night stand.

The opportunity arose when one week later, after the seven days were up, Dean checked her injury and decided that it was time to remove the stitches. Though an uncomfortable, but not painful process, Erin still hated the procedure. The constant tug and pull at the freshly healed skin was a disgusting feeling and she wasn't looking forward to it, but she bravely took her seat at one of the tables in the library and let Dean do the work.

They were both silent the entire time, Dean's mind too preoccupied to keep a conversation going.

"Alright, all done. You're good to go." He announced when he was finished, and after inspecting her shoulder blade, he added, "Healed up pretty nice."

Erin groaned, slightly annoyed. "Great, just another ugly-ass scar to add to my already extensive collection."

She shocked herself with how bitter she sounded and when she saw the sympathetic expression on Dean's face, she quickly looked away, not able to bear it.

"Sweetheart..." He started softly and she quickly shook her head for him to stop. "Don't. Please... just don't..." She was close to tears and turned her back on him to take a deep breath and calm herself.

She felt Dean's gentle touch on her back and before she could react he had pulled her to his chest. She relaxed into his arms and he just held her for a while.

"You're a hunter. Our life's rough, we go into battle and try to come out alive. Every scar is a token." Dean whispered into her hair and started to run his hand slowly up and down her back for comfort. "But those scars don't define you and they don't make you less beautiful. You're the most gorgeous girl I've ever seen, you hear me? Don't you dare think otherwise."

He felt her nod against his shoulder before she pulled away and looked up at him. "It's just... I've been feeling pretty down this past week and I need my best friend back."

"Hey, you can always come to me, you know that, right?" Dean reassured her, searching her eyes for the reason to her miserable state.

Erin bit the inside of her cheek, hesitating. It was now or never, she had to make a move.

"Dean, what is going on between us?" Her heart pounded violently against her ribcage as she waited for him to answer.

"I... I don't know..." He breathed out and looked away from her, his gaze flickering across the room instead. "I mean, I didn't mean for this to happen, hell, I never thought... you and me... it's just crazy, you know... but I was so riled up after the hunt. You were just there, right in front of me and half-naked, can't blame a guy for getting weak, you know?" He added with a chuckle and Erin thought she was going to suffocate as the pain took hold and strangled her.

She kept up the facade, giving him a forced smile. At least she had tried.

Nodding, Erin turned to leave, but then stopped in her tracks and faced him again. "Do you want me to leave?"

When Dean just stood there and didn't respond, she was forced to elaborate. "You've been acting like a complete weirdo since we had sex. I don't want to make things more awkward between us, if you can't live with me under the same roof I'll go. Be honest, it's okay. My time here with you and Sam had to come to an end."

Dean didn't catch a word because he had spaced out and pictured sex with her again. Briefly, he shook his head in confusion when the rest of her speech finally reached his brain.

"Wait, you don't wanna stay here because of that one night?"

"I do want to stay, but apparently you can't live with what happened between us."

"No, Erin, I don't want you to go. You're my buddy, I need you here." He hurried to appease her, and to make light of the situation he added, "You can't leave me, you're the only one who keeps me and Sammy from killing each other. Why would you wanna leave?"

Erin raised an eyebrow, staring at him dumbfounded. "Because you don't want me here. You barely talked to me for a whole week. I thought you didn't want me around after we fucked because it was a huge mistake to bang your friend."

Dean took a deep breath and confessed, "That's not the reason I stopped hanging out with you."

"Okay..." Erin said slowly, trying to guess what he was hinting at.

"I mean, yeah, it was awkward to see you after that and I felt so stupid, but..."

Erin waited patiently for him to go on, making him even more uncomfortable than he already was.

"God, you're gonna hate me, Erin." Dean rubbed his neck nervously and let out a heavy sigh. "I'm an ass for even thinking…."

"Dean...?" Erin said, her stomach turned at the serious expression on his face. He was starting to scare her. "Talk to me please."

Dean let out a tortured groan and turned his back on her, fidgeting with the pages of a book on the the table. "What happened between us... I don't regret it, okay. I wanna do it again."

There. He had said it. Before Erin had the chance to react, he spun around and finally made eye-contact with her.

"Listen, before you bite my head off... I'd never do anything to destroy our friendship, believe me. I've known you for so long… our friendship is more important to me than sex."

"Wow, coming from you, it's gotta mean something." Erin replied with a little smile.

She wanted to tell him that it was fine and he didn't have to worry, but Dean continued rambling. It was like a dam had broken and all the thoughts that had been running through his mind for the past seven days finally poured out.

"I know how this sounds, you must think I'm a jackass, that I made a move on you on purpose... but I never intended to sleep with you, not that you're not hot, 'cause you are, but you're my friend and I care about you and..." He interrupted himself and licked his lips.

Erin watched him in amusement, but didn't say anything.

"I'm so sorry, Erin... I want you so much, it's killing me, you know. I can't stop thinking about that night." He looked defeated, like a beaten puppy.

Erin crossed the room, walking over to him slowly. "Dean, it's okay. I'll always care about you, nothing's gonna change that."

Dean huffed, staring at a spot in the library above her head. He couldn't bare to see the look on her face. "Yeah, right. I bet you can't even look at me right now."

Erin cupped his chin and tugged his head down until he was forced to meet her eyes. "Dean, honey... Did it ever occur to you that, maybe, I was feeling the same, you dumbass?"

Dean blinked a few times as it began to dawn on him what she was trying to tell him, but he didn't dare hope. "What...? Erin, are you saying… you want to have sex with me?"

"Exactly. Every night… I wanted to crawl into your bed every night, because I can't stop thinking about you. I want you, Dean. Honestly, it freaks me out to say it, but I want to sleep with you again."

Dean laughed at her words, feeling the nervousness dissipate and relief wash through him instead. "So, what are we gonna do about that now?"

"Well, I was thinking..." Now it was Erin's turn to grow nervous. She felt her face turn red and started fumbling with the hem of her shirt.

"So... here's the deal, you wanna fuck me and I wanna fuck you… why don't we just go ahead and..."

"Fuck?" Dean ended the sentence for her, kinking his eyebrow, a wicked grin appearing on his face.

"Yeah. I'll be happy to help you out whenever you need to relieve a bit of stress. Friends with benefits, what do you say?" Erin said with a playful sparkle in her eyes.

Dean pursed his lips as he considered the offer.

"But only if you stop acting like a douche afterwards." She added in all seriousness, all playfulness gone. "I don't want this to affect our friendship."

"It won't. It's not gonna be the end of our friendship if we do this, I promise." Dean said sincerely.

Erin smiled and stepped closer to him, slowly sliding her hands up his biceps until she could lock her arms around his shoulders. "Good. I take you at your word. Now… my wounds from the hunt are all healed up and I could use some lovin' after the week I've had..." She whispered quietly and Dean pressed her closer to him, tightening his hold on her.

"Then we can try a few different positions, am I right? I wanna do so many bad things with you..." He brushed his lips carefully against hers, in case she changed her mind and wanted to pull away.

Erin giggled against his lips and stood on her tiptoes to press her mouth firmly on his. "You know what? You can slip into me bare if you want to… I want to feel all of you…."

Dean groaned and leaned his forehead against hers. "Fuck, what are you doing to me, baby girl?"

"You don't have to if you don't wanna risk anything, or if it's too messy for you..." Erin continued to tease, but then let out a yelp when he suddenly lifted her up and headed for the hallway. "Last chance to back out, sweetheart. You really want this?"

"Yeah, I really want it." She confirmed as he carried her through the bunker.

"Good." Dean smirked and entered his room, kicking the door closed behind him.

He threw her onto his bed and she laughed happily, hands instantly popping the button on her jeans and pulling the zipper down as she looked up at him. He tugged his flannel shirt over his head, exposing his broad muscular chest and Erin bit her bottom lip at the sight of this gorgeous man above her.

Looking at her intently, without breaking eye-contact, he opened his jeans and freed his cock, giving it a few strokes as he watched her squirm out of her pants.

She was taking too long though and he slapped her hands away, grabbed the waistband with both hands and tore her jeans and panties off of her in one smooth movement. Erin yelped and then laughed at his impatience when her hips were suddenly being lifted off the mattress. Dean was ready to devour her and she revelled in the feeling.

She expected him to push into her without delay as he yanked her body to the edge of the bed and threw her legs over his shoulders. But then he got down on his knees and his head disappeared between her thighs.

"Let me taste that pussy first." He rasped against her skin. His tongue licked a broad stripe through her folds and then plunged forcefully inside her. Erin gasped and buried one hand in his hair with a whimper. Her heart picked up pace, she started to feel hot all over.

"So wet." Dean growled, looking up at her with a smirk before grazing her clean-shaven mound with his teeth.

Erin tensed up at first, but quickly relaxed and gave in to the pleasure with a deep moan when he pushed his tongue inside her again. He groaned at the taste and slickness of her, sending vibrations through her pussy and lower body.

A sheen of sweat formed on her skin, her throat went dry. Dean Winchester was between her thighs, eating her out.

He kept swirling his tongue inside her, massaging her walls and when he inserted two fingers easily into her, her opening closed up around him. Dean's cock twitched in response, begging to be pushed into her heat.

Dean's nose bumped against her swollen clit with every swipe of his tongue, his stubble causing a prickling sensation along her wet and sensitive folds. Erin whimpered and lifted her hips into his mouth, needing more of him. She didn't want him to ever stop.

He removed his tongue and eased back a little, licking his lips and watching her as he pumped his fingers lazily inside her. Her eyes were closed, nose scrunched up as she writhed in the sheets. She must have felt him looking at her because her eyes fluttered open. Her irises were dark, pupils blown with lust, cheeks turned pink.

Dean smiled at her wickedly and added a third finger, penetrating her deep and rubbing against the delicate, but slightly rough patch inside her. His lips closed around her wet folds, sucking and tugging at the soft skin before letting go and licking up the gushes of slickness trickling out of her.

Erin's hips rose off the bed forcefully, bucking into his face as she sought more friction. Dean gripped her thigh almost violently and pinned her hips down, holding her easily in place. She made a sound in protest, but he quickly appeased her.

"Shh, shh, hold still for me, darling." He murmured against her pussy, eliciting another moan followed by a whimper from her.

He knew she wanted his mouth on her clit but he didn't want to let her come yet. Instead, he flicked the little bundle of nerves with his tongue a few times, then lightly dragged his teeth across it, making her jump and cry out.

"Dean..." She whined and clawed at his hand around her thigh, her nails digging into the back of it, but he didn't mind.

He pumped his fingers faster, adding more pressure to her sweet spot and finally sucked her clit into his mouth. Her hips started to move uncontrollably, chest heaving with each deep breath, the hold of her fingers in his hair tightened and she tugged at the strands, causing Dean to hiss at the delicious pain against his scalp.

"Oh my God, Dean, yes! Make me come!" She panted.

More arousal built between her thighs, he felt her pussy clench against his mouth and fingers, felt more juices coating her folds and dripping down his hand. She was close and he released her swollen throbbing clit from his mouth and pressed two fingers on the little nub instead, continuing to rub shallow circles.

"Oh God… please… I can't…." She wailed helplessly. Her body was so tense, wound tight. She was desperate for an orgasm.

"You're doing so good, baby. So beautiful, such a good girl for me." Dean praised and caressed her trembling leg with his free hand, stroking from her knee all the way down to her hip. "You taste so good, baby girl. I don't want it to end so soon."

Mercifully, he stopped tormenting her clit and she ceased writhing in his hands. He turned his head and kissed along her thigh, nibbling on her to tease her before she felt him suck hard on her skin.

"Son of a bitch!" She huffed in frustration as she realized that he was marking her.

Dean laughed again and continued to kiss and nibble down her inner thigh. When he reached her pussy, he wedged his hands underneath her ass and lifted her closer to his face. He placed hot open-mouthed kisses along the length of her, feeling her tremble and whimper, and then started licking through her folds to lap up her arousal.

She twitched and bucked in his hands, pushing at his head, but he crushed her to his face, effortlessly keeping her from moving away from him. When he had licked her clean, he closed his lips around her clit and sucked long and hard without letting up. Erin squirmed and squealed, moaned and whimpered, tugging at his hair and scratching at his forearms.

One scorching hot spark after another shot through her, increasing in intensity until her orgasm flooded through her and she came hard, body shaking. She made a series of such beautiful noises, her sweet pussy constantly dripping for him.

Dean never let go and didn't stop pleasuring her. He licked and sucked on her folds, lapping up her juices with greedy slurping sounds and possessive growls. She whimpered and writhed against him, sobbing quietly at the overstimulation, but he still continued to nibble, suck, and lick until he tasted more slickness on his tongue.

He noticed that her hand was shoved under her t-shirt and she was squeezing her breast and pinching her nipple. He moved his own hand up her stomach to her other breast, cupping her gently and teasing the hardened peak with the calloused pad of his thumb.

Erin shivered and then sighed blissfully, arching her back to press more into his touch. "Fuck… Dean…. that's it…."

Erin was so swollen and sensitive, she didn't think she could come again so fast, but when he sucked her clit into his mouth she came undone yet again.

"Oh God… Dean… no!... Dean..." She gasped in shock, moaning loudly. Her orgasm rippled through her deliciously, spreading warmth through her veins.

Dean sucked on her clit until she was spent and fell back on the bed, panting heavily.

He leaned up a little, licked his lips and wiped his mouth with his hand. He looked at her with a grin. "That's my girl, coming for me so good. Beautiful."

Erin blushed and covered her face, giggling hysterically.

"I could eat you all day, sweetheart." He growled, his words an exciting threat. She felt the bed dip and then he forced her hands from her face and she saw him hovering above her. He crushed his mouth to hers, kissing her hard and deep.

His hand tangled in her hair, his tongue plunging into her mouth and a heatwave swept through her lower body when she tasted herself in the kiss. She caressed his chest with boths hands, letting one trail down his stomach and wrap around his length. He twitched against her palm, hard and wet with pre-come. Dean growled low in his throat and thrust into her grip.

Without breaking the kiss, he pushed his opened pants and boxers down to his thighs, she spread her legs further for him and he knelt between them and took hold of her thighs, pushing into her hard. He grunted at her wet pussy wrapping around his bare flesh for the first time. Erin cried out and gripped the bedsheets above her head, moaning low in her throat as he started to move instantly.

He lifted her hips off the bed, holding her tightly to him as he thrust into her.

"Fuck… Erin…" He groaned, sliding easily in an out of her with deep long strokes. "Baby girl… you're taking me so good…."

She squeezed her eyes shut, an embarrassingly loud moan tearing from her at the sensation of his hot hard flesh rubbing her walls. No condom was preventing her from feeling him this time, she felt every ridge, every vein with each drag of his hard length.

"Oh Dean… Fuck!" She yelped when he hit her sweet spot over and over. "Fuck… you feel so amazing… we're never using a condom again…."

Dean laughed breathlessly at her words. He squeezed and kneaded her ass since he knew how much she liked it.

He watched with hooded eyes how she moved one hand down her body and started rubbing her clit furiously. Her back arched and she bit her lip, whimpering quietly.

"Don't stop, keep hitting my spot…." She pleaded, "Please…. I'm so close… so close..."

Dean cursed when her walls squeezed down on him and he pushed her legs to her chest, folding her body in two and leaned into her, picking up pace and driving into her with quick, sharp, punishing thrusts. He took hold of the edge of the bed for more purchase and aimed for her sensitive spot.

Dean was panting heavily as he pounded her sweet tight pussy, hitting her spot repeatedly and fighting the urge to spill his seed into her when she squeezed harder and harder around him until her body tensed. She screamed, her pussy milking him almost painfully and he managed to thrust into her two more times before he felt the prickling sensation intensify and he had to let go.

He growled and came with a deep groan, the thought of spilling inside her and marking her with his essence heightened his orgasm. He collapsed on top of her, breathing heavily. After a minute, he felt Erin place a kiss to his forehead, run a hand through his hair. It made him smile.

"Wow." She croaked. "I really didn't think I could come a third time… damn..."

"Gonna make you come a fourth time, baby girl." He turned his head and pulled at her earlobe with his teeth. She trembled but stayed silent.

"Sweetheart?" Dean inquired, "I scare you?"

"N-no, I just… I've never come four times in a row. Even when I'm masturbating, it's usually twice, three times tops..."

Dean lifted himself off of her to look into her face. He raised an eyebrow, admiring her flushed, heated face with a wicked grin. "I can make you come a fourth time, promise."

He caressed her damp hair, rubbed his thumb over her bottom lip. "My sweet baby girl, dripping wet for me each time… and all mine to play with."

She swallowed hard, heart beating fast at his words. Her pussy pulsed, a new surge of wetness pooling between her thighs.

"I felt that." Dean chuckled darkly. He pulled out and rolled off of her onto his back, making her whine in protest. "No…. Why?"

"C'mere." He said softly and pulled her to his chest, his hands trailing down her body, groping and caressing.

Her nails raked over his torso, grazing his nipples as she kissed along his jaw, down his neck. Dean hissed and grabbed her ass roughly, rubbing his cock against her stomach. She let up and took his face between her hands and pressed a kiss to his lips instead, teasingly pushing just the tip of her tongue past his lips, quickly pulling back before he could swirl with his own against hers. That earned her a hard slap on her ass, making her gasp.

"Fucking tease." He scolded playfully as he rubbed her cheeks. She pressed harder into him, rolling her hips against his, chuckling deviously.

"Oh that's how you wanna play it, sweetheart?" Dean growled, moving over her and forcing her onto her back. "I know just how to torture you, baby girl."

His hand wandered from her ass to her pussy, his fingers swiping through the mess of their mixed juices and spreading his come all over her pink folds. She screwed her eyes shut and squirmed under his touch, letting out a choked sob.

"How do you like that, huh? Wanna come again, darling? So hot and wet, covered in my come, I could fuck you all day and night, come inside you over and over until you're begging me to stop." Gently, he eased two fingers inside her, teasing her a little before pulling out again.

"Open up." He brought his wet fingers to her mouth and she parted her lips willingly, sucking and licking his come and her own wetness off. She hummed, feeling a rush of excitement as she tasted him for the very first time.

"Good girl." He praised with dark eyes, and licked his lips as she released his fingers from her mouth. He tucked a strand of hair behind her ear and cupped her cheek, leaning in and pressing his lips to hers, pushing his tongue inside her mouth and groaning deep in his throat as he massaged her tongue with his.

Erin was surprised that he didn't mind tasting his come on her tongue but then it occurred to her that she should have known that it was quite the opposite; that it would even turn him on.

"Touch me, baby girl. Need your hand." He guided her to his half-hard length trapped between their bodies and Erin felt a breath of warm air in her hair when he let out a groan as she closed her fingers around him.

She moved her hand slowly up and down twice before tightening her grip and stroking him more firmly. Erin dragged her bottom lip through her teeth in concentration as she worked him, watching him grow to full hardness from her ministrations again.

"Fuck... that's it… just like that… so good, baby girl… fuck, your hand is so tiny compared to mine…" Dean grunted, bucking his hips into her strokes.

Erin raised an eyebrow, squeezed him a little harder and swiped the pad of her thumb over the tip. "Is that good or bad?" She teased.

Dean laughed breathlessly. "It's fucking amazing, I'm trying so hard not to spill right now, just so I can see my come drip down your hand."

"Oh God, Dean..." She couldn't believe it but she blushed at his words.

He rolled onto his back and Erin leaned on his chest, continuing to stroke him as his hips kept rocking gently into her hold.

"C'mon, hop on, ride me." Dean commanded suddenly, his voice dark and gruff. "I want you to ride me."

Unexpectedly, he grabbed her hips and lifted her onto him, making her squeal and let go of his cock.

Laughing, she straddled him and got into position. "Alright, big boy. If that's what you want..."

Dean crossed his arms behind his head and looked at her with a challenging smirk. "Your arm's all healed up. Now show me what you got, sweetheart."

"You're such an ass." She shook her head at him, grinning.

Dean had closed his eyes and was waiting patiently for her to take him in. Oh Dean, so full of himself and cocky.

She was gonna fuck his fucking brains out until he was a begging mess underneath her.

Erin got up onto her knees and reached behind her, taking hold of his cock again and guiding him to her opening. She pushed him just past her swollen lower lips and when she was sure that the head was settled inside her nicely, she quickly sank down onto his entire length in one quick move.

Dean flinched, eyes shooting open as he was suddenly enveloped in hot silky wetness. "Fucking hell!" He cursed loudly.

Erin snickered devilishly. Slowly, she started to move. Closing her eyes and rocking gently just for her own pleasure, sighing blissfully each time she impaled herself on him and every single hard inch of him rubbed against her aching walls.

She felt his hands on her thighs, sliding higher up her body, and she quickly grabbed them and forced his arms above his head, pinning his wrists down. Dean looked up at her in surprise.

"Oh no. No hands, Winchester." She reprimanded him with a smirk, never ceasing her movements. "You don't get to touch me. Not until I tell you to."

"But… that's torture." He protested weakly, brain fuzzy from the sensations of her slippery pussy going up and down on him.

She just laughed at how helpless and defeated he sounded. Of course she knew that he was physically a whole lot stronger and could easily overwhelm her despite her being a hunter herself. But his eyes glazed over, turned dark, a deep black lake in the middle of a forest. He was going to obey, do anything she asked of him.

"I'm gonna use you, Dean. Gonna bounce on your cock until I come again and you're gonna be a good boy for me and take it." She increased her pace, still holding his hands down and moving above him so her clit got enough stimulation with each drag and her breasts were practically bouncing in his face. She saw him lick his lips; he was tempted to take her nipple into his mouth but refrained himself from doing so.

"Do as I say, baby, and I'll suck your pretty cock and even let you come in my mouth." Her smirk widened when he groaned, his fingers tightened their hold on hers and she could just tell from the strain in his arms that he was tempted to crush her into the mattress, take control of the rhythm and fuck her senseless.

His eyes fluttered closed and he relaxed, clenching his jaw when she squeezed her inner muscles around him. Erin cupped his face with one hand and leaned in to suck his bottom lip gently into her mouth.

She slowed her rhythm until she was circling her hips slowly, her hand working on her clit. She moaned quietly at the heat pooling between her thighs.

He made a humming sound deep in his throat when she clenched tighter around him and Erin felt that he was close. Dean tried to make her change the pace and raised his hips, pushing harder into her, but she squeezed her thighs around his hips as a warning and he gave in.

"Such a good boy. Hold back for me just a little longer." She praised, and Dean gritted his teeth with a strangled moan.

She changed her position slightly, leaning back and placing her hands on the bed for more leverage, her legs unfolded until she could plant her feet firmly on the mattress on either side of Dean's shoulders and raise herself off of his cock with the help of her hands and feet.

"Oh holy hell…. Shit!" Dean cursed when she presented herself that way for him and he could watch his cock disappear into her pussy. She was dripping wet, arousal trickling from in between her folds, her little clit was wet and swollen, begging to be touched.

Dean licked his lips and struggled to keep his head lifted up so as not to miss the show. He panted heavily, a grunt escaping him from time to time. She pumped her hips frantically, impaling herself on his cock again and again, moaning deep in her throat.

"Fuck, Dean… so close… your cock's so amazing… can't get enough..." She panted, meeting his gaze.

He stared at her with those dark green, almost black, eyes and slightly parted lips. "You like that, Dean? Watching your cock slip into me and filling me? "

"Fuck, yes… so hot… need to touch you, please. Please. Let me touch your pussy." He begged, head falling back into the sheets when she took him in again and squeezed around him.

"Go ahead, Dean. Rub my clit, make me come. So fucking close…." Breathlessly, she gave him permission to do whatever he wanted to her.

Her clit throbbed painfully, the head of his cock kept bumping her sweet spot as well as her cervix on each thrust, but she was needy to come and needed a little extra stimulation. Dean's fingers rubbed teasingly the spot where they were connected which made her whine and falter in her movements.

She wriggled her hips, making him hiss and he obeyed, pressing down onto her clit and rubbing hard and fast to bring her to completion. Her body tensed and she cried out, but still attempted to move and slide up and down on his cock.

"Yes! Fuck, yes! Oh God..." She squeezed her eyes shut as her inner walls clenched painfully, her head thrown back, hair brushing along Dean's legs.

"Oh fucking hell, sweetheart. Come on my cock, I wanna feel you drip all over me. Please."

She let go, spasming around him so hard that he felt dizzy. Sheer willpower kept Dean from shooting his load into her.

He rubbed her through her orgasm until she went limp and fell back on him, head between his shins.

"Fuck, that was amazing." She panted as she lay there.

Dean caressed her knees and thighs, gritting his teeth. His cock was painfully hard and wet from her. He didn't dare move.

"Sweetheart, I'm begging you… get off me or I'll come inside you." He chocked out.

"Oh that's right. Sorry, baby." She leaned up and slid off of him carefully. His cock bobbed when her body released him and he hissed in pain.

"You were such a good boy for me, Dean. You deserve your reward." Instantly, her lips closed around the head of him and she took him a few inches into her mouth in one go, gagging slightly.

"Oh fuck! Erin!" Dean exclaimed in shock, his body jerking. "Careful, sweetheart… I don't want you to get hurt..." He bit out through his clenched jaw, his hand tangling in her hair, keeping her head in place. He wanted to thrust up into her mouth so badly, but forced himself not to.

She held his hips down to keep him from bucking into her mouth and managed to take him in a little further, wrapping her hand around the rest of his cock that didn't fit in. She moaned at the taste of herself on his hardness, mingling with his own, and Dean cursed and panted at the vibrations she sent through him. She started bobbing her head, pressing her flat tongue firmly against the underside of his length, hollowing her cheeks and sucking on the tip each time she reached the head of his erection.

"Babe, I'm not gonna last..." Dean panted and she squeezed his thigh in reassurance, allowing him to let go.

She managed to slide him into her mouth a third time, letting him bump against her throat. Dragging her lips back up to the head, she knew he was going to shoot his load right this instant.

He pulsed against her tongue and hand and then he erupted in her mouth.

"Erin..." Dean warned, his hand tightening in her hair, but it was already too late.

She sucked his come from the slit, licking up his length to catch the droplets that were trickling down to her hand. She licked him clean, swallowing everything he had to give her, teasing his slit with the tip of her tongue one last time before releasing him.

She squeaked when she was suddenly picked up and dragged onto his chest, his mouth crashing to hers.

"Erin, my sweet baby girl… fuck.. the hell was that?" He looked up at her in awe, breathing heavily. He had never expected her to take control like that.

Erin laughed happily. "I take it you liked that? I'm amazed how long you managed to hold out."

"Only because I wanted to feel your mouth a little longer. It was too short." He rasped against her lips.

She raised an eyebrow. "Who says it was the last time? With such a pretty cock like yours, I'll give you as many blowjobs as you want, Winchester." She said huskily.

He cursed loudly again, making Erin laugh. She tucked her head under his chin, sighing at the feeling of his fingers combing though her hair, stroking down her back.

They lay in post-orgasmic bliss for a good fifteen minutes before Erin stirred. Dean tightened his hold on her. "Hell you doin'?" He breathed in her hair.

"Shower. I'm all sticky, it's disgusting." She untangled herself from him and got off the bed. Dean grumbled something incoherent, turned onto his stomach and buried his face in the sheets.

Erin stepped under the shower, grinning happily from ear to ear at the thought of Dean. He had brought her to four fucking fantastic orgasms and she had completely worn him out in the process. She was quite proud of that.

Whatever might come, whatever still lay ahead of them, whatever the consequences of their little arrangement, she was positive that she was never going to regret it. If it ruined their friendship in the long run, so be it.

Erin lathered herself up, her palms sliding over her breasts and nipples as she closed her eyes. His broad chest was suddenly pressing to her back, strong hands taking hold of her hips.

"Dean – " She exclaimed before his hand clamped down over her mouth, he lifted her leg and forced himself inside her with a deep grunt. She cried out in surprise as his rock-hard cock pressed into her and spread open her abused and overstimulated pussy.

Her heart beat in her throat, her pussy gushing with new slickness as the heat in her abdomen intensified and Dean pumped himself into her body, growling and panting into her hair.

He showed her that it was possible for her to come a fifth time.

Erin was glad that her screams of pleasure were muffled by his hand. Otherwise, Sam might have heard them even through the soundproofed walls of the showers in the bunker.

No, having sex with her best friend had definitely not been a mistake.
