Author note: Hey guys, I'm am so super sorry for the lack of update. Life has been rather hectic. I am hoping to update this story every one to two weeks. Please be patient with me? Enjoy x

Tony squeezed Pepper's thigh as he slowly pounded into her. Pepper moaned and Tony smiled.

"Pepper…" Tony said, nuzzling into the crook between her neck and shoulder. Pepper was immediately reminded of Clint moaning her name when she'd sucked him off the night before. She pushed this memory from her mind and focused on Tony.

His hand slid up her body, leaving a trail of goose bumps behind. He weighed her breast in his hand before sucking and licking her nipple. Pepper's thoughts immediately flashed to when her and Natasha had fooled around – to try and get Pepper comfortable with being with just a woman. Tony suddenly thrusted hard and Pepper gasped with pleasure.

"Like it a bit rough Miss Potts?" He growled in her ear. Pepper gulped and nodded – thanks to the two assassins she'd been fucking for the past week or so. Tony bit at Pepper's ear and she gasped and shivered again. He kept thrusting and Pepper grinded her hips. Soon both of them were moaning heavily. Tony thrusted hard once again and Pepper moaned loudly as she came. Tony came a moment later. Both of them lay there, waiting for their breathing to calm. Tony slid out of Pepper and moved to be beside her. Pepper moved to be close to him and Tony held her.

Guilt ate at Pepper. She had been cheating on him for a week and she couldn't bear it. No matter what way she looked at it, it was cheating and she hated herself. She was meeting Natasha and Clint the next day and planned on working out a 'getting-Tony-into-bed' plan.

"I love you Pep," Tony said sleepily, his arms tightening around her slightly.

"I love you too." She murmured, guilt aching through her again.

Tony woke before Pepper the next morning, despite the fact Pepper had work that day. He got up slowly, so not to wake Pepper, before wondering out into the kitchen. Tony was tempted to try and make breakfast but knowing his track record would probably burn it. It was then that he noticed Pepper's phone. A small icon was flashing on the screen showing 3 new messages. Tony decided to check them, in case something was happening at Stark Industries. As he reached across the table for it, Pepper's sharp voice rang through the kitchen.

"Tony!" He looked up to see Pepper's wide eyes looking worriedly at him.

"Are you okay?" Tony asked, forgetting the phone and walking over to her. Pepper blinked and realised her almost mistake.

"I just didn't know where you were." She mumbled, looking at him with a smile. Tony smiled in return.

"I'm right here." He kissed her forehead. "I'm going to shower now, okay?" Pepper nodded and Tony moved past her. Pepper breathed a sigh of relief and walked over to her phone. She unlocked and quickly read the messages from Natasha and Clint. She grinned at the dirty things they'd sent her.

Pepper slowly walked through the halls of Stark Tower, following the discarded pieces of Natasha's and Clint's clothes. She listened for moans and possibly screams but heard nothing.

Finally Pepper arrived at one of the unused bedrooms, Natasha's thong hanging from the door handle. She pushed open the door to find the room empty. The door slowly swung shut behind her and then suddenly Pepper found herself being pushed back against the door, her hands pinned above her head. Clint was then kissing her roughly, his naked body hard up against hers. His hands made light work of her clothes and they were soon on the floor. Natasha watched from the bed, her hand slowly rubbing her pussy.

Clint then stopping kissing Pepper and got down on his knees in front of her. Pepper grinned down at him, her fingers sliding through his hair. Clint immediately began to kiss and lick at Pepper's pussy and she closed her eyes, moaning. His tongue began to dart in and out of her folds, soon rubbing her clit. His fingers trailed up her leg to then finger her. Then he switched – his tongue slid in and out of her, massaging inside her while his fingers teasingly ghosted over her clit. Pepper moaned again and Clint pulled away. Pepper almost growled and Natasha let out a small giggle. Her hand had still been slowly rubbing herself the entire time, despite how wet the sight and sounds were making her.

Clint then picked Pepper up – she wrapped her legs around him and his cock brushed against her. She moaned again – she'd been so close when he'd been on his knees. She squirmed in his arms, trying to get more but Clint was too strong. Pepper felt herself be lowered into a chair. She wrapped her arms around his neck, trying to hold him to her but the assassin's had other plans. Natasha made her way over and pulled one of Pepper's arms down. Pepper looked to see a strip of black cloth being tied around her wrist and the leg of the chair. She looked up to Natasha, who winked. Clint was busy tying the other arm and then both the assassins stepped back. Pepper looked at them with confusion.

"Pepper, breathe. We've been taking it easy on – you're new to the whole rough thing. But Tasha and I want to go all out. And we want you to watch. The thing is, we don't want you touching." Clint said and Pepper relaxed slightly. She was still wet and wanting to cum but the thought of watching Natasha and Clint, while it didn't help the wetness matter, would make waiting worth the while.

Natasha stepped over to Clint and began to nibble at his neck. Clint immediately pulled her close to him – she wrapped her arms around his neck and Clint lifted her up, Natasha's legs wrapping around his waist. Clint laid Natasha down on the bed and grinded on her slowly while she continued to kiss, lick and suck at his neck. Natasha finally pulled away and Clint captured her lips in a hot kiss. Natasha sat up and then rolled them so she was on top. She grinded on Clint while his hands squeezed her arse.

Pepper watched, waiting, wanting. She could feel the tension building in both Natasha and Clint and it caused more to build inside her.

Clint flipped himself and Natasha so she was underneath him, completely at his mercy. He straddled her and began to lick between her breasts. He then trailed kisses across to her left nipple. He licked the nipple over and over, knowing how it would get to Natasha. She curled her hands into fists, trying not to react in any other way. Clint then took the nipple in his mouth and sucked hard. Natasha's hands now spread wide while her hips bucked up slightly. Clint grinned and rubbed his tongue over the nipple as he sucked on Natasha's big tit. Clint's other hand slid down her body, leaving a trail of goose bumps. He lifted his hips up and his hand continued down to teasingly rub over Natasha's slit. She shivered and he pulled away from her breast with one final suck. He began to nibble and kiss at her collarbone and neck while his fingers began to rub her clit, slowly and tantalizingly. It was then that Natasha moaned and something seemed to snap inside of Clint – pure dominance came over him and the roughness of his movements showed it.

He pulled away from Natasha and she looked at him with a lustful smirk on her face – she knew how to handle Clint when he got like this. Her hand slowly trailed down her body and began to rub where Clint's fingers had been a moment ago. Clint slapped her hand away.

"69, now," was all he said in a harsh tone. Natasha complied, knowing this would work out well for her in the end. Clint laid down and then Natasha knelt over him. She teasingly swirled her tongue around the head of his cock and Clint tightly gripped her thighs. Natasha lowered her hips and Clint began to tease her slit. She moaned, her tongue still rubbing over the head of his cock. She then wrapped her lips around the tip and sucked lightly. Clint darted his tongue into her pussy before teasing her again, his tongue ghosting over her clit. Natasha took in more of his cock, her tongue running up and down the underside. Clint bucked up a tiny bit, his hands squeezing Natasha's thighs.

Pepper watched on, her eyes wide. She was practically dripping wet now and watching Natasha and Clint was not helping. She fought against the bindings around her hands but to no avail.

Clint was now running his fingers up and down the inside of Natasha's thigh while his tongue licked her clit. Natasha was slowly taking more of him in as she rubbed her tongue all of over his cock. Clint's fingers moved to tease Natasha's hole and she moaned, her lips tightening on his cock. He slid a finger in, moving it in and out slowly, still teasing her. He sucked her clit and Natasha pulled away from his cock, her breathing heavy. Clint didn't seem to mind, enjoying the effect he was having on Natasha. He slid another finger inside her and Natasha moaned. Clint got faster, his tongue and lips still kissing, licked and sucking her clit. He knew Natasha was close – he could feel her pussy tightening around his fingers. He flicked his tongue against her clit and Natasha clenched tightly again – the tightest yet. She cried out, her hips rocking back and forth as Clint continued to finger-fuck her. Natasha came and Clint kept up his ministrations, keeping her high going.

"Clint…" she murmured and Clint knew it was time to let her pull away – but he wasn't done with her yet. He let go of Natasha and she almost fell to the side. She immediately got up and reached out to stroke Clint's still rock hard cock but he slapped her hand away again.

"All fours now, baby," Clint said, weighing Natasha's breast in his palm before nipping at her ear. Natasha complied, baring her arse to Clint. He ran his cock over it, leaving a trail of pre-cum. He pushed down on her back and Natasha arched willingly. He then thrust into her pussy from behind, causing both Natasha and Pepper to cry out. Clint looked to Pepper and winked before beginning to fuck Natasha.

Clint was rough, his hands tightly gripping Natasha's hips. He leant forward, their bodies almost melding. His hand roughly gripped Natasha's tit as he kissed along her shoulder.

"You're my dirty little whore, Natasha… Say it, say you're my little whore," he whispered to her and Natasha moaned, already tightening around his cock. Natasha loved it rough and dirty talk was always a part of their rough nights. Clint roughly thrust into her and she almost whimpered. "Say it… say it, my good little whore," Clint became still and Natasha moaned. She made to get up and turn the tables on Clint but he clamped her hands down with his own.

"I-I'm your dirty little whore," she whispered and Clint pounded into her once again. Natasha cried out, her pussy tight around Clint's cock. "Yes, yes, yes," she chanted. Just as she was about to cum, Clint pulled away. Natasha whimpered and fell forward, her forehead touching the mattress.

"You'll cum when I say you can… my little whore," Clint taunted Natasha and she got up and jumped on him. They battled for dominance – Natasha kissed Clint's neck while his fingers immediately went to rub Natasha's sensitive clit. She moaned and weakened – Clint then flipped them. They landed so Natasha's head was just off the bed and Clint straddled her, the tip of his cock rubbing against her hole. Clint looked down at Natasha with a smirk and she growled at him. Pepper moaned at the sound.

Clint thrust into Natasha causing her to gasp. He fucked her hard and fast – Natasha knew he wanted to cum too now. She moved her legs to wrap them around his hips and Clint moved closer to her. Clint kept pounding into Natasha and soon she was moaning again. Clint leant forward and began to suck on one of her nipples.

"Yes…" she breathed, her hips coming up to meet Clint's.

"Cum for me baby," Clint whispered to her as he kissed across the suck on the other nipple. As his tongue swirled around her hard nipple, she gasped and arched her back. Natasha came again, her climax increased from her head being half off the bed. "Baby, let me go," Clint said, pulling away from her boobs. Natasha let herself relax and Clint pulled out after one more thrust, coming up her stomach, some reaching her chest. Clint leaned down and lightly kissed her pussy. He then looked up to see Pepper half thrusting in the chair they'd stuck her in. He got up (on somewhat shaky knees) and knelt in front of Pepper. His tongue darted in and out of her and she moaned, heavily.

Natasha came over after cleaning herself up undid the ropes of Pepper's hands. She then kissed Pepper, her tongue running over the other woman's bottom lip. Pepper moaned and Clint sucked on her clit. She pulled away from Natasha as she came, her hips thrusting up toward Clint's face. Natasha smirked and walked over to relax on the bed again. Clint lightly pecked Pepper on the lips. Both Clint and Pepper joined Natasha on the bed. They all sat in silence for a moment.

"So, how are we going to involve Tony?" Pepper asked and Clint and Natasha smirked.

It was Tony and Pepper's date night and Tony was eagerly awaiting Pepper's text telling him where to go. Finally his phone beeped.

"57 East 57th Street." Was all the message said. Tony looked at it with confusion before asking JARVIS to get directions for him. Tony looked at the screen and then grinned.

The drive didn't take long since Tony didn't really stick to the speed limit. He parked out the front of the hotel and then made his way inside.

"Hi, there should be a room booked under the name of Stark… or Potts?" Tony said to the boring woman behind the desk.

"Yes, room 69, sir. Here's your key. Enjoy your stay," she handed him the key and Tony made his way upstairs.

Pepper, Natasha and Clint had arrived about half an hour earlier than Tony to set up the room – there were candles covering most surfaces and the normal boring cotton bed sheets had been changed (by the trio) to satin. They'd also put a bottle of chocolate sauce and a bowl of cut up watermelon on one of the nightstands. The bed was on the diagonal right to the door and Clint had set up two chairs a metre or so away from the bed for him and Tony to watch from.

They'd decided that, instead of trying to explain to Tony what was going on, they'd show him. So now, as Tony was walking up the corridor, Natasha was hovering over Pepper, both of them naked with their lips locked, and Clint was sitting in one of the chairs, a glass of wine in one hand, his slowly hardening cock in the other.

Pepper tensed as she heard the key in the door and Natasha tried to soothe her with soft kisses trailing up and down her neck. The door opened and Tony entered.

"Pep- what the-?" at the moment Tony had entered Natasha had sucked on Pepper's neck and the other woman had gasped with pleasure. Clint grinned and took a sip of his wine before turning to Tony.

"Hey, Tony," Clint said simply, gaining the other man's attention. Tony's face contorted with shock and a tiny bit of disgust as he realised Clint was naked.

"What the fuck?" Tony exclaimed as he raised a hand to cover his eyes while Clint laughed.

"Please, Tony, it's not like you haven't seen a naked man before." Clint said, sipping from his wine again as his eyes drifted to the two women on the bed. Tony peeked through his fingers to follow Clint's eyes. He was growing more confused by the second.

"Okay, does someone want to explain to me what the hell is going on here?" Tony spat, watching as Natasha's tongue swirled around Pepper's nipple. Clint grinned as Pepper moaned, her fingers tangling in Natasha's hair. Clint made his way to stand behind Tony.

Tony froze as Clint came to stand behind him. However, as Clint pressed up against him, his cock hard against his arse, Tony's blood pumped. He'd been with men in the past, although it had been a while, so Clint's close proximity wasn't an issue.

"Basically, Mr Stark," Clint breathed in Tony's ear. "Natasha and I are… recruiting some new sexual partners – namely the Avengers and theirs. It's been a while since we've explored and we thought, why not? We asked Pepper a little while ago and my god, she's been fun. The thing was, she was missing you. So Natasha and I caved and decided to invite you to the party." Tony shivered as Clint's teeth nipped his ear.

"So… so you three just fuck? And you want me to join you?" Tony said, his eyes glued to the two women on the bed. Things were still heating up slowly, as per the plan.

"Another guy always makes things more fun… And your suits might come in handy," Clint grinded his hips against Tony's arse and Tony gulped. Pepper looked to Tony from the bed – her eyes were filled with lust and she winked at him. Tony nodded. "You're in, then?" Tony nodded again. "Good- now strip off and come watch the show." Clint pulled away with a kiss to Tony's neck. He poured a glass of wine for Tony while Tony stripped down to nothing.

Tony was feeling rather nervous – true, he had been very adventurous in his sex life. However it was always with people he would probably never see again. This was different – this was with the woman he was in a relationship with and two master assassins. Fuck.

Tony made his way over to the chair beside Clint, accepting his wine graciously. He would have preferred something stronger but nevertheless. Both men's eyes were glued to the two women on the bed.

Pepper and Natasha were sitting up now, their lips locked. Natasha was the dominant one, as she had been in hers and Pepper's previous encounters. Pepper's hands slid up Natasha's stomach to cup her breasts, the nipple hardening under her palm. Natasha moaned into Pepper's mouth, pressing forward toward her.

Natasha broke the kiss and began exploring down Pepper's neck, to nip at her collar bone. Pepper squeezed Natasha's breast in her hand before Natasha pushed it away. Natasha kept moving down Pepper's body, her head stopping between Pepper's breasts. She began to lick at the soft skin and both Pepper and Tony moaned – the contrast of Natasha's fiery red hair and Pepper's pale skin had Tony rock hard.

Natasha continued to lavish attention on Pepper's breasts – she kissed and sucked and squeezed. Pepper was getting closer and closer to coming when Natasha's fingers moved down to rub Pepper's clit. Pepper gasped and opened her eyes to see both Tony and Clint with their hands on their cocks, slowly stroking up and down. A seductive smirk appeared on Pepper's lips and she pushed Natasha away. Natasha fell backward onto the bed, looking at Pepper with surprise.

Pepper moved across to grab a piece of watermelon. Natasha's eyes darkened as Pepper ran the pink fruit over her lips. Pepper took a bite out of the fruit, letting some of the juice trickle down her chin. She then ran the rest of the piece over Natasha's breasts, causing Natasha to groan. The fruit was cool on her warm skin. Pepper then began to lick up all the juice, the sweet taste of the melon mixing well with the taste of Natasha. Then Pepper popped the rest of the fruit in her mouth.

"More?" Natasha asked, her hand moving down rub her own clit. Pepper's eyes widened and she nodded, reaching for more fruit. Pepper traced the fruit over Natasha's well-toned stomach, her tongue catching all the droplets of juice. Natasha was shaking slightly, her fingers now inside her. Pepper pulled away, going for another piece of watermelon when Natasha stopped her. "Your turn," she said sexily and Pepper nodded. Natasha lay Pepper down and reached for the chocolate sauce.

Both Tony and Clint were panting heavily over the scene in front of them – the girls were working painfully slowly and neither of them wanted to miss a thing. Both men longed to join in with Natasha and Pepper but knew the women wouldn't allow it.

Natasha had opened the sauce and was now pouring tiny amounts onto Pepper's nipples. Natasha then lowered her head and let her tongue trail all over Pepper's breast. Pepper moaned and wiggled underneath. Natasha smirked wickedly before licking Pepper's nipple, spreading the chocolate about and catching some on her tongue. Pepper moaned again as the new sensation spread through her.

"Tasha, please…" Pepper moaned and Natasha moved to the other breast – her tongue made light work of the sauce there and she made to make her way down to lick Pepper's pussy. "No…" Pepper moaned and Natasha looked at her with confusion. Pepper sat up so she and Natasha were kneeling, facing one another. "No time for that," was all the explanation Pepper gave.

Pepper's hand slid down to rub Natasha's pussy and Natasha quickly caught on. Pepper rubbed her clit and Natasha moaned, her hands moving to Pepper's pussy. Clint and Tony watched with eager eyes as the two women began to rub and finger-fuck one another. All four of them were moaning and all of their hands were working fast. Tony reached over to cup Clint's balls as Natasha took Pepper's nipple in her mouth once again. Both Clint and Pepper gasped, their hips thrusting up. Pepper was practically writhing, her pussy tightening around Natasha's fingers. Natasha lightly bit on Pepper's nipple and Pepper gasped, thrusting up as she came. Natasha soon followed as Pepper's fingers darted in and out of her while her thumb massaged her clit.

Tony and Clint moaned and their hands worked up and down. Soon they both spilled over, their cum shooting over their hands.

It was silent in the room, aside from everyone's heavy breathing. Pepper looked to Tony with a worried expression. Tony simply shook his head and smiled at her. Pepper breathed a sigh of relief. Then Tony's eyes looked over both Natasha's and Clint's sweaty bodies. He grinned.

"Oh, I am most definitely in."
