Michelle was still obediently bent forward at the waist, her elbows locked behind her arched back. Her bare legs were parted, her g-string around her knees, her pussy dripping wet from the vigorous fingering she'd just received.

She tried to calm her breathing and looked lustfully at Dave, her husband. Dave was sat on the sofa, fondling the bulge in his trousers. His cock had grown steadily harder as he'd watched his friend, Andrew, masterfully coax his wife into an extreme state of arousal.

She was so turned on by his lewd suggestions that she'd just agreed to be Andrew's fuck slut, to be used and abused however Andrew saw fit. And her first task was to willingly take a good, hard spanking in front of her husband.

Andrew stepped up next to Michelle and reached under her belly with one hand, his finger finding her clit, the touch instantly causing Michelle to gasp. "You might want to brace yourself. Hold onto my leg," said Andrew. Before she'd managed to adjust her position there was a loud smack and Michelle felt the sharp sting on her arse cheek as Andrew spanked her hard, almost causing her to fall forward.

"Oh my God!" said Michelle, as she grabbed Andrew's leg for support, but before she could react further Andrew smacked her hard again on the other cheek. He continued his onslaught, alternating between each arse cheek, at the same time rubbing her clit with his other hand. The mixture of pleasure and pain was amazing. "Oh -- my --- fuck..." was all she could manage as Andrew spanked her about 20 times before finally stopping, leaving Michelle breathless, the burning sensation intensifying as the blood rushed to her backside.

Andrew continued to rub her clit, "You see, Dave. This is how your wife secretly yearns to be treated. But it takes a real man to know how to do it, isn't that right Michelle?"

"Yes -- Sir," was all she could manage as she looked sheepishly towards her watching husband.

"Hmm, such a lovely, spankable arse," observed Andrew as he gently fondled her soft, red cheeks. He stepped behind her and pressed himself against her arse. Michelle could feel his hard-on through his trousers, like an iron bar being held against her openings.

"Can you feel how excited you've made me Michelle?"

"Yes Sir," she gasped.

"What do you think we should do about that?" said Andrew as he rubbed himself up and down against her arse crack.

Michelle hesitated, looking to Dave for re-assurance. "You could -- fuck me?" she suggested, still a little unsure whether her husband was still OK with this whole arrangement.

"You hear that Dave?" said Andrew, "Your wife said I could fuck her. You don't mind if I give her a good, hard fucking right here and now, do you Dave?"

"No," Dave shifted uncomfortably but it was also obvious he was turned on.

"... Sir," he added, as he saw the stern look that Andrew was giving him.

"Good," continued Andrew, as he fondled Michelle's arse, noting how it was soft and fleshy yet perfectly shaped. "Tell me Michelle, has anyone ever fucked you here?" He pressed a finger onto Michelle's arse hole, causing her to squirm.

"No," answered Michelle in a wavering voice.

"Really?" said Andrew, "Not even your husband?"

"No, he's not interested in that," said Michelle, blushing slightly at admitting she'd asked her husband to do it, and that he'd said no.

"So your arse hole is a virgin arse hole?" went on Andrew.

"Yes."

"Well, maybe I will fuck you later, Michelle."

Then he whispered in her ear, "Maybe I'll fuck your virgin arse and make you scream in front of your husband."

"Ohh, fuck," Michelle shuddered.

"But first," continued Andrew out loud, "I want to find out if you're any good at giving head. Get down on your knees."

Michelle did as she was told. Andrew kicked off his shoes and undressed until his lower half was naked, his hard-on pointing towards the ceiling. Michelle was impressed with how hard Andrew's cock looked. Her husband's erections seemed almost placid by comparison.

"Show me how you suck cock," ordered Andrew.

Michelle was too afraid to both disobey and to look at her husband. She reach for Andrew's cock and pulled it down, enveloping it with her mouth, sucking and lubricating it as best she knew how, bobbing her head back and forth, while massaging his balls.

"Ooh, fuck, yes, excellent," exclaimed Andrew, "Dave, you cunning fox. You didn't tell me your wife was such a good cock-sucker. I can see why you married her. That's it, Michelle, can you go deeper? Yes! That's it, go on, all the way to the balls. Good girl!"

Michelle knew how to suppress her gag reflex. Her husband had taught her that. And now she was putting that skill to good use with her husband's best friend.

Andrew stood with his hands behind his back, his legs stiffening to thrust his cock forward as Michelle sucked on him with the expertise of a top porn star.

"Ooh, yes, I could fucking get used to this, you dirty bitch. Hold on." Andrew grabbed Michelle's hair and pulled her head back. "No hands. Put them behind your back, lock your elbows like before," instructed Andrew.

"That's it," said Andrew as he held onto Michelle's head, one hand scooping her hair into a bunch, the other hand held under her jaw. "Just hold that position. I'm going to fuck your mouth now."

Andrew brought his cock to Michelle's mouth. Michelle had to lift herself up onto her knees, her hands still behind her back as Andrew forced his way in. He shoved his cock deep into her mouth and out again, establishing a slow fucking rhythm, each time pulling Michelle's head hard onto his cock, causing her to almost choke as it hit the back of her throat.

"Oh, yeh, fuck, that's it. Good girl. I'm fucking loving your wife's mouth," taunted Andrew, "I may have to come round more often and make use of this dirty little bitch's mouth."

Andrew looked toward Dave to make sure his gibes were having the desired effect. Despite the fact that Dave had wanted this, agreed to this, even encouraged his wife to seduce Andrew, it suddenly dawned on him how things might pan out. Having a threesome seemed like a great idea at the time. But now there was the possibility of Andrew visiting on a regular basis to make "use" of his wife, while Dave would be powerless to stop it. That wasn't something Dave had thought about properly.

And what if Michelle fell in love with Andrew? She might decide she'd rather be him. Then divorce would be on the cards. What had he let himself in for? Dave pushed the thought to the back of his mind to try and forget it. For now, he couldn't help noticing how incredibly erotic he found the site of his wife, propped up on her knees, doing her best to avoid choking as Andrew forced his rigid cock into her mouth while staring directly at him.

Andrew knew this was making Dave uncomfortable, and it turned him on immensely. Dave may be his boss at work but now it was he who had the real power over Dave. From now on, Dave would do anything Andrew said. He'd have no choice if he didn't want people to find out about this. Better still, he could have his wicked way with Dave's wife, whenever he wanted, getting her to perform all sorts of humiliating sexual acts, perhaps even in the office, and forcing Dave to watch every sordid bit of it. "This is going to be fun," he thought, as he smiled to himself.

"Ugh, yeh," said Andrew, as he rammed his cock deep once more into Michelle's throat, "God, your wife’s good."

He pulled out because he could feel his orgasm brewing. He slapped his cock against Michelle's cheeks, smearing her face with her own spit.

"Lick my balls, Michelle. And look at your husband as you do it. Show him how much you enjoy worshiping my cock and balls."

Michelle did as she was told. It felt dirty and naughty but she did it anyway. She looked over at her husband with a lustful expression as she sucked and slobbered loudly on Andrew's balls. Her husband was now clearly stroking his erect cock through his trousers, obviously turned on by the show she was giving him.

"Yeh, you like watching your wife doing this, don't you Dave?" questioned Andrew, "Why don't you get a bit closer, get a good view?"

"That's it," continued Andrew as Dave got down off the sofa to sit on the floor, "I bet you'd like more than to just watch, though, wouldn't you? I bet you'd like to join in too, eh?"

"Oh yeh," breathed Dave, a look of excitement on his flushed face as he got up onto his knees.

"I thought so," said Andrew, "In that case, why don't you show me you can lick balls as well as your wife can?"

"What?!" Dave nearly chocked, "I thought -- I mean..."

"Oh, fuck yeh, Dave," Michelle cut in, "that would be so fucking kinky. Go on darling, do it, for me, will you -- please?"

"You're serious?" Dave was still in a state of shock at the thought. This is not something he'd bargained for.

"Oh my God, yeh," said Michelle, "that would really turn me on. I mean it."

Dave looked at his wife and then at Andrew's rock hard cock only a foot or so from his face, "I don't know about this."

"I'm waiting," said Andrew, impatiently, his hands on his hips, "You heard your wife. Get on with it. And don't just take a stab at it. I want you to take your time, put some feeling into it, like your wife did. Make me believe you're enjoying it."

Dave had never so much as touched another bloke's cock before but he had to admit to himself that he'd fantasized about it before. Maybe now was the time to live out one of his fantasies. His wife was looking at him in a pleading way. He could see how much she wanted this. "OK then," he whispered as he leaned forward and tentatively licked the underside of Andrew's scrotum. The scent of Andrew's sex filled his nostrils. It was intoxicating. Andrew's cock and balls were slimy from the thorough blow job his wife had just given him. But that didn't seem to matter. If anything, it made it more dirty. He felt himself getting turned my the humiliating act of licking another man's balls while his wife watched, clearly enjoying the unfolding scene.

Michelle breathed a husky, "Ugh, yeh, that's it, you dirty boy. Lick his balls like a good little slave."

"Very good, Dave," said Andrew, "That wasn't so hard was it? Now show us you can suck cock as well as your wife can."

Dave was past caring now, his mind a fuzz of lustful feelings that were controlling his actions. He took Andrew's cock into his mouth and began sucking at it with a passion.

"Oh. Fuck. Yes." breathed Michelle, "That is so fucking kinky."

Andrew grabbed Michelle's hair. "Stand up," he ordered and pulled her up beside him. He put his arm around her back and held her close, fondling her arse. They both looked down at Dave as he sucked Andrew's cock.

"You're enjoying this, aren't you Michelle? Watching you husband suck on my cock."

"Oh, yeh, I fucking love it."

"Tell me, Michelle, who's in charge here? Who's the boss now?"

"Oh, you are Sir. You are so definitely in charge."

"That's right. I am. I could cum in your husband's mouth right now and he'd let me, wouldn't he?"

"Oh, fuck, yeh.

Are you going to?"

"Maybe. Would you like that?"

"Oh, God, yeh, please. Shoot your load into my husband's dirty mouth."

Andrew smiled. "You're as kinky as I am, aren't you? We're going to get on really well, you and me. Now kiss me while your husband sucks me."

"Yes -- Sir," breathed Michelle. She put her arms around Andrew's neck and snogged him passionately, her feelings for her husband momentarily forgotten. They kissed for several minutes, lost is the moment. If it wasn't for the noise of Dave slobbering on Andrew's cock, they may have forgotten he was actually there. Finally, Andrew pulled away and stared into Michelle's eyes.

“Wow,” whispered Andrew, “electrifying. You have a lovely kiss."

"You too," said Michelle, licking her lips and smiling.

"I think I'd like to fuck you now. Stand over there," ordered Andrew, "assume position one, as I showed you earlier."

"Yes, Sir," responded Michelle, excitedly. She did as she was told.

Andrew pulled himself out of Dave's mouth and bent down to whisper in his ear, "You've been enjoying that, haven't you, dirty boy?" As he said these words, he groped Dave's crotch and could feel how hard his penis was.

Dave squirmed under Andrew's touch, "Yes, Sir. I liked doing it."

"Glad to hear it," continued Andrew, then more seriously: "I'm going to fuck your wife now. While I do, I've got one more little task for you."

Michelle was stood in the position she'd been instructed to resume, bent forward, her arms locked behind her back, her legs parted, her head raised to keep her back arched and her arse sticking out. She couldn't quite hear everything Andrew and Dave were whispering about. She just caught the last part of the conversation:

"Will you do that for me?" said Andrew as he gave Dave one last stroke of his cock through his trousers.

Dave shuddered at the touch, ”Yes, Sir, I will.”

"Good boy," said Andrew, as he gave Dave a gentle, friendly slap on the side of his face. Andrew straightened up and walked toward Michelle. He couldn't help but admire her perfect, young arse and legs on show as he moved his cock towards her exposed openings.

"God, I've fantasized about having my wicked way with you for ages, Michelle. Now I'm finally going to get what I've secretly yearned for.” He slipped his cock between her moist pussy lips and thrust into her, causing Michelle to gasp out loud, "Oh my God."

Andrew held onto her delicious hips and rammed her hard. "Damn, that's a nice fit. I'm going to enjoy using your tight cunt on a regular basis, Michelle. In fact, I think it would be a good idea if you phoned in sick on Monday, don't you? And while you're husband's hard at work, we'll fuck each other all day long. I'll even fuck you up the arse. Would you like that, Michelle?"

“Ugh — yes, Sir," moaned Michelle, "I'd like that very much." Michelle was well aware that her husband was in the room listening to these adulterous plans but she was past caring by this point.

Dave, her husband, in the meantime had been quick to position himself for the little task that Andrew had asked him to perform. He couldn't quite believe what he was about to do but he was so turned on right now, it was as if he wasn't in control of his own actions. The thought of doing it would have been repulsive if he'd been in a normal frame of mind. But in his highly charged erotic state, the fact that it was disgustingly dirty just served to spur him on.

He knelt behind Andrew and paused for a moment to watch as Andrew vigorously banged Michelle while she was bent over, facing the opposite direction. He could tell from her loud moans and heavy breathing that she was clearly enjoying the thorough fucking she was getting. Rather than feeling jealous, he was actually turned on by knowing that his lovely wife was getting the pleasure she deserved. He proceeded to do what Andrew had instructed. He placed his hands on Andrew's arse and parted his cheeks. Then he stuck his tongue up Andrew's arse hole.

"Ugh, yeh," growled Andrew as he felt Dave's tongue up his arse. He thrust his cock deep into Michelle's cunt and held it there.

"Do you know what your husband's doing right now, Michelle?" question Andrew. "He's got his filthy tongue right up my arse."

"Wha..." Michelle was taken aback. She glanced round to see Dave knelt behind Andrew. She couldn't quite see her husband's face but it was clearly planted up Andrew's arse right now and what's more: he seemed to be enjoying it!

"Oh fuck, yes," Michelle looked back at Andrew and reached behind to urge him to continue fucking her. "You're such a dirty, kinky man. I fucking love it."

Andrew was in his element. He loved the fact that he'd discovered Dave and Michelle's kinky, submissive side. Now he could dominate both husband and wife, forcing them to do all manner of filthy things for his own personal pleasure. He fucked Michelle with abandon now, her sopping wet cunt tight around his rigid cock. He could feel her pathetic husband doing his best to slide his tongue up and down his arse crack while he fucked the guy's wife. He could feel his testicles rubbing against the worthless fool's chin stubble, the sensation rather enjoyable, causing his balls to tighten as a powerful orgasm began to build.

"Ughh, fuck, yeh," Andrew gave one last thrust before pulling out and stepping to one side. "That's enough you dirty perverts. You're gonna make me cum, and I'm not quite willing to let that happen just yet."

Michelle dropped to the floor next to husband, both of them red-faced, breathing heavily, sweating and exhausted. Andrew grabbed Michelle by the hair and dragged her onto her hands and knees in front Dave. "Get your head down slut and arse up in the air," growled Andrew as he shoved Michelle's head into their lush living room carpet. He gave her delicious arse a sharp slap, causing her to moan with delight.

"Now, Dave," continued Andrew, "you're going to watch me take your young wife's virgin arse-hole. Trust me, she'll love it. This is what she wants, Dave. It's what she's been on at you to try but you've never been man enough to do it. After I've finished with her, I doubt you'll ever be able to satisfy her again."

On that note, he crouched behind Michelle and pressed his cock into her arse-hole. It was so moist, it didn't need much persuading to open up. He slowly eased his cock in and back out again, gradually ramping up the rhythm.

"Ohh, fuck me, yes," Michelle moaned into the carpet, "God, that is so nice."

Andrew pounded down hard on Michelle's arse as she held it up with her knees on the carpet. He grunted loudly as he forced her down toward the floor, "Yeh, you're secretly a dirty, little anal whore, aren't you, Michelle? This is what you've been longing for, isn't it?"

"Yes, Sir. Take my arse, Sir. Oh -- fuck -- it's yours, Sir -- yours to take whenever you want. Ugh -- fuck -- me."

Andrew stretched his legs out straight and pressed down onto Michelle, forcing her almost flat onto the floor. He was fucking her arse like a possessed demon, now. He could feel a tremendous orgasm building.

"Oh, fuck, yeh. I'm gonna cum. I'm gonna -- fuck -- I'm coming. I'm gonna fucking cum in your dirty wife's arse, Dave," groaned Andrew as he looked towards Dave. He felt his balls tighten and his sperm squirt into Michelle's arse hole, stream after stream of cum flowing into her tight hole. It felt like his orgasm would never end. It had been a while since Andrew had last had sex and he could tell there was a lot of cum this time. When his orgasm finally subsided, he pulled out and a trickle of cum oozed out of Michelle's arse and onto the luxurious, red carpet that lined the couple's living room. For a brief moment, he felt guilty that it might leave a stain. Then he smiled at the idea, his feelings transforming into a strange sense of pride. It was as if he'd left his mark, a permanent reminder of the hold he now had over both husband and wife.

Michelle, panting heavily, made to sit up but Andrew told her to wait, "Hold on, Michelle, I haven't finished with you yet. Dave, get over here. Lie on your back on the carpet. It's time for you to give your wife some pleasure."

Dave, who had been jerking off while watching his wife being fucked, did as he was told and positioned himself on the floor.

"Stand up Michelle," continued Andrew, "but be careful not to leak any of that cum in your arse. That's it. Now stand over your husband and lower yourself onto his face. That's it. Lean back a bit. Put your arse on his mouth."

Michelle looked down at her husband. She couldn't help but feel exhilarated by this sordid act of humiliation. Andrew held Michelle's back with one hand as she squatted down onto Dave's face. With his other hand he slipped two fingers into Michelle's cunt and started fucking her rapidly with his hand, his thumb massaging her clit.

"O - M - G," said Michelle as she felt her body tensing, out of control.

"I'm going to make you cum," taunted Andrew, "I want you to cum so hard that all my spunk will ooze out of your arse. I want you to smear your perverted husband's face with my cum, Michelle. Will you do that for me?"

Michelle was too far gone to speak. She looked at Andrew lustily, her face flushed red, her nostrils flaring as she felt an irresistible urge growing deep within her loins.

"That's it, Michelle," Andrew went on, "do it. Cum for me, my dirty little fuck-slut. Wipe my dirty arse-spunk all over your feeble husband's face. Mark him for me. Show him that we own him."

Andrew didn't need to go on. Michelle suddenly tensed up. She could feel Andrew's cum leaking out of her arse into Dave's mouth. The delightful kinkiness of humiliating her husband in this way drove her to the edge. She momentarily stopped breathing before her body started to shudder violently. She screamed so loudly as her orgasm raged uncontrollably. She was briefly conscious of the fact that it was the early hours of the morning and she desperately hoped the neighbours didn't hear her screaming.

Finally, exhausted, she unsteadily tried to get to her feet as Andrew helped her stand. Andrew held her close and kissed her passionately. They ignored her husband, Dave, who was still lying on the floor, his face covered in Andrew and Michelle’s sexual juices.

“So,” said Andrew, breaking the nervous silence, “did you enjoy your first taste of my deviant little world, Michelle?”

“Yes, very much.”

“Good. I have lots of plans in mind for you. I can promise you that it will get even more perverted from now on, for both you and your husband. Are you happy to continue with this arrangement? I can walk away now and we can forget all about it, if you feel the slightest bit of guilt,” continued Andrew as he put his clothes back on.

“Are you kidding?” said Michelle, “It was amazing. I want to carry on with it.”

“Excellent. Look at that. The sun’s coming up. We’ve been at it most of the night. Dave, why don’t you go and get cleaned up, mate. And when you’ve finished, make us some breakfast, will you? Your wife and are starving.”
