Gym Instructions

I arrived home early expecting the house to be empty; instead I found Anne's car and her fitness instructor Rob's car parked in the driveway. I had met Rob several times at the gym myself and he would occasionally come over for extra sessions with both of us, so I didn't think anything of it. I parked the car along the road and walked back home. I couldn't get my key in the front door so went around back and let myself in the back door. There was soft music playing which I assumed was from the lounge and another sound which I couldn't initially place.

Whatever it was stopped me from calling out, and I walked along the corridor towards the lounge and the sounds got louder, then I heard my wife, Ann cry out which left me in no doubt what was happening the other side of the door.

"Oh yes Rob just there, right there that feels so good, finger my cunt get it good and wet for your big cock"

I was taken aback and stopped in my tracks, my stomach was churning, my heart was beating hard and fast, and my mouth went dry. Then as the realisation that my wife was obviously being fucked by Rob, my senses started to return. Instead of wanting to rush in and stop what was going on, I found myself wanting to see what was happening. I retraced my steps and went into the Dining room which backed onto the lounge and found I could see into the lounge without giving away my presence. I looked into the lounge and saw my wife naked but for a red Basque and a pair of red stilettos bent over the back of our sofa, Rob who was totally naked, was giving her cunt a good fingering and was squeezing her tits with his other hand.

His fully erect cock was bouncing against his stomach and a pair of heavy balls swung between his legs. Without so much as a groan he lifted my wife with one arm spun her around, so her head was nearest the ground and her legs above his head. He held her up by wrapping his arms around her waist and she placed her thighs over his shoulders. He had easy access to her sopping wet pussy. She had unhindered access to his rigid cock. The scene was highly arousing as I watched my wife being tossed around by this hunk like she was a rag doll.

Ann had her hands on his thighs and her mouth wrapped around his cock, her head bobbing on its length. He was lapping at her pussy like a bear eats a pot of honey. Me, well I was desperately trying not to come in my pants. I loosened my belt and undid my zipper allowing my trousers to drop to the floor around my ankles. My underwear quickly followed and my erect cock, which was as hard as I had ever experienced, sprang free. My balls were taut and hard and ached with the knowledge of what would happen shortly.

I took a firm grip on my rigid tool, and returned to the sexually arousing scene I had come upon, my emotions were in turmoil. My wife was cheating on me, but instead of anger I was so aroused and desperately wanting to witness the outcome of whatever they were going to do together. They were still in the standing sixty nine positions and Rob was by now face fucking my wife, who by now had her hands firmly gripping his buttocks and appeared to be pulling him towards her eagerly awaiting mouth. The sounds of their lovemaking accompanied the soft music which had aided my unheard approach, to where I now stood unseen and unheard.

Rob then flipped her over, and almost threw her onto our sofa, her pussy glistening in the ambient light coming from the two lamps on the mantelpiece. Rod then grabbed her ankles and lifted her legs back onto his shoulders. Placing his cock against the entrance to her pussy he allowed his weight to push his cock into my wife's pussy. Ann was moaning throughout this, and it got louder as Rod went deeper;

"Oooooh Mmmmph!....Oh yes oh god yes fill my cunt you fucker"

Rob adjusted his feet once he was fully entered and then began to slide that cock in and out at a steady pace.

"Now you cock teasing bitch, prepare to be fucked senseless"

Rob gradually picked up the pace until I thought our sofa was going to break, so hard were his thrusts. My wife gripped the front edge as he hammered her pussy into submission. Her small body bouncing up and down as he did as he had promised, and fucked her senseless. Ann was grunting and groaning, like an animal at the fucking she was receiving. Shouting in between thrusts, dirty talk she had never been so far gone like this before;

"God, oh fuck, yes fuck, fuck, and ooohhhh yesssssss"

"Fuck me stud, fuck me, fuck my cunt, fuck it good you bastard" she yelled.

"Go on fuck the arse right of me, fuck my cunt like only you can you fucking stud"

Rob was like a steam piston driving in and out of my cheating slut of a wife's cunt. Every time he rammed in a frothy mix of her juices and his precum, squirted out of her abused hole and dripped of his balls and dribbled over the front of our leather sofa. I was frantically wanking myself silly, my cock felt so hot, it ached with anticipation of the inevitable load my balls were getting near to shooting up its length, they were also so fucking sore I thought I would surely damage them.

Ann was in the throes of yet another orgasm, her body shaking and her legs flapping around above his head, the red stilettos making it look as slutty as Rob battered my wife's cunt into oblivion. This stud sure knew how to dish out a good hard fucking, such as I could never dream of delivering. I felt the familiar tingling in my balls, my legs started to shake and I had to grip a nearby cupboard to steady myself as I shot my load over our carpet. The first shot must have went five feet from where I stood, the next three or four working their way back towards me, until the last few spurts or rather dribbles ran down over my hand as I continued to pump my still erect cock, again a first for me, as I usually went limp after Cumming.

I gently massaged my ball sac with my other hand until my balls began to drop back down from disappearing up inside my groin, and then gently began to pull and tease them trying to ease the aching pain I was feeling.

I returned to watching the two lovers, in time to see Rob lift her up from the sofa. Then he half pushed half placed her over the back of the sofa, her ravaged cunt gaping open and covered in the mixture of their combined juices. Her ass stuck up in the air and her head hung over the back of the sofa as she tried to regain some form of composure. Rob walked around the front of her and holding her head up by grabbing a handful of hair shoved his sticky coated cock into her mouth.

"Now suck it clean bitch, and don't take forever that pussy of yours needs more cock"

My wife Ann obliged him and used her hands to lift his heavy ball sac up so she could clean them off for him also. Then Rob who had been holding her hair grabbed her head with both hands and began shoving his cock down her throat. Ann was making loud gagging sounds and I could see spit flying from her lips as Rob fucked her face like he had her cunt moments before.

"This'll teach you to be such a cock tease at the gym you fucking slut" he grunted

"From now on, you'll be my fuck toy to do with what I want bitch, no more teasing just plenty of cock and plenty of spunk for your slutty holes"

All Ann could do was moan and groan as he never eased up to allow her to answer. Rob began grunting loudly and I saw his cock twitch, my wife's eyes bulged and her throat was making frantic swallowing motions. I realised Rob had dumped a load down her gullet. This had me as hard as a rock again. My right fist was beating my cock frantically, my aching balls were slapping against my thighs which felt like jelly. But I wasn't ready to release another load just yet despite that all too familiar feeling. I wanted more, I wanted to see if my wife would beg him to stop or admit he had shagged the arse of her as he had stated.

After Rob had cum he pulled out and slapped my wife's face with his cock, calling her a fucking whore and a filthy slut, who was only good for fucking. To my amazement Anne was agreeing with him;

"Yes, yes I am, treat me like the cheap two bit slut I am".

"My husband's cock won't be enough for me now stud I need your big cock"

"Oh you'll get plenty of this bitch, more than you could ever hope for and maybe some other cocks as well"

"I know a few of the guys who want to help teach you a lesson for your slutty cock teasing ways. I will be only too happy to let them join in bitch, now bend over the back of this sofa till I fuck that cunt of yours again"

Ann quickly got into position, the look of lust on her face giving away how much she was enjoying being fucked by this stud. It was obvious she was so hot and in need of Rob's cock inside her already well used cunt.

Rob stood behind her and spread her ass cheeks apart; he began by teasing my wife, rubbing his saliva coated cock over her clit and gently pushing his head against her cunt entrance. Then he slowly eased the first few inches of that glorious fuck rod into my wife's cunt. I watched mouth gaping open, cock pulsating balls tingling as he eased it in slowly inch by glorious inch, her cunt stretching and opening up for him. I could only imagine how stretched and filled she felt.

Rob was filling her cunt, to the limit. When he was finally all the way in Ann sighed and turned her head around to look at him;

"Now you bastard fuck me, and fuck me hard the way I like it"

Rob began to oblige my wife's request, slowly at first, grinding himself fully into her, his thick cock and heavy balls rubbing and banging against her clit, almost immediately I saw Ann's legs shake and she let out a low moan

"Oh God I'm fucking cumming I'm cummmmmming"

Rob grabbed hold of her hips and began to pound her really hard, the room was filled with the sounds of sex and the smell reached my nostrils heightening my own pleasure. My own fist flying up and down the length of my own cock in time to Rob's pounding of my wife.

"Oh fuck fuck I'm gonna cum again you bastard, I'm gonnaa......Aaaaaaah"

Anne's legs visibly collapsed causing her to push even harder against Rob's penetration which in turn prolonged her orgasm. Rob still kept at her faster and harder he seemed to go. I thought to myself god this man fucks at a phenomenal pace, it's like watching a steam trains driving rod. Her pussy was oozing juices all over Rob's balls, the sofa back and Rob's thighs. Each time I thought Rob was about to dump his load in her he seemed to restrain himself. I could hear his thighs slapping loudly against my wife's ass, the loud dirty squelching sounds, the constant moans and grunts of pleasure coming from my wife, who I knew had never experienced a fucking like she was getting right in front of me.

As I shot another load over our carpet, Rob was indeed nearing his final moments as he began grunting;

"Jesus, oh fuck yeaah, take it bitch take it"

Every stroke penetrating my wife to the limit

"Here it comes bitch, Fuck Ooooh Yeeeeah"

I saw his bum cheeks clench, and his heavy balls visibly started to lift and pulse with each shot he was firing into her cunt. He finished emptying his load and gave her several long hard thrusts to ensure he had filled her belly with as much of his cum as possible. My wife laid limp and moaning over the back of our sofa. Rob stepped back and I saw her gaped, ravaged hole spunk oozing out in great globs, over her thighs and our sofa. I thought to myself wonder if that will mark it, stupid I know, I decided to retire so grabbed my discarded clothing and retreated to the back door dressed quickly and returned to my car. I drove around for about an hour and returned to find Rob just leaving; I knew they had obviously fucked again.

I got out and Rob smiled at me and said;

"Hi, just been giving your better half a good workout"

As I shook his hand I thought I know you have and hopefully I will get to see you give her more extra workouts soon.

I had enjoyed the initial interlude between my wife Anne, and her lover Rob so much that I had created as many opportunities as I possibly could to allow their adulterous affair to continue without them knowing that I knew. It is as many of those in the same position will vouch for not as easy as it seems, and on more than one occasion I suspected my wife had discovered my secret voyeuristic desires. However they continued their affair, and I continued watching as often as time and work would permit.

We had over the past few months seen our planned, home gym extension completed. Although nothing flash, it was fitted with the usual equipment. A selection of cardio-vascular, weights and smaller items, you would expect in a home gym. There was also a large walk in shower and changing area, in all, it was about the size of a double garage.

This had been put to good use by both of us, as well as allowing Rob to increase his programmes for Both Anne and myself. It was upon my return one morning after forgetting a folder I needed for a meeting that I found Rob and Anne testing the equipment out in a far more enjoyable way than was intended.

Upon return to the house, I discovered Rob's car already in the driveway. I knew right away that he wasn't due that day so that could mean only one thing, he was giving Anne some of his special one on one exercises. I called the office to let them know I was feeling a bit ill, and asked my secretary to reschedule my meeting for the next day.

I entered the house, to find music playing, not to loud but audible, coming from the direction of the gym, where I suspected the two of them would be. As I got nearer, I could hear the music was, coming from our new Gym, so I crept quietly towards the changing room door. I tried opening the door slowly, just in case they were in there. However I breathed a sigh of relief, the room was empty; also as there were no windows in the room it was almost in total darkness.

The door that led to the gym was however slightly open, I approached the door that led to the Gym and noticed it was being held open by a bath robe hat had been discarded. My luck was in; I would be able to use the gap between wall and door, or even the gap at the hinge end, to see what was going on in the Gym.

I already knew what a slut my wife Anne, could be from past experiences. On this occasion even by her standards, she was going to burst that visionary bubble. What I saw through that gap, was about to change my life forever. I was about to witness her being gangbanged. Not only was Rob there, but also Andy, a co-worker from the Gym and last but by no means least, her own boss from her workplace, Bill. Bill was a rugged man, who looked after himself, for a fifty year old guy was as fit as any twenty five year old.

As I looked into our home gym, the sex party was already well started. I saw my wife Anne, on all fours, with Rob's big cock buried in my wife's cunt doggie style. Bill was stood at her head, Anne, had her mouth wrapped around his cock. Andy meanwhile groped her tits whilst stroking his own cock. "Wow, what great tits; I love playing with them."

Rob, had dropped to his knees behind Anne, he was now lapping at her cunt like a thirsty dog. His hands were clasped tightly to her butt cheeks and he used his thumbs to hold her thighs open to allow him access to her dripping snatch. "I love eating this bitch's pussy, it tastes so good."

"Ooh Yes Mmmph!.. Oh god yes right there... you fucker! Lick me harder!.. Right there!" Anne groaned between mouthfuls of cock. Rob lapped harder at her cunt, making her groan even louder.

Bill was shoving his cock into her mouth, pulling it out and slapping her face with it. "Suck it! Come on, suck it bitch! Suck it like you fucking mean it!"

Anne had by now also got hold of Andy's cock which had been flapping around in her face, whilst he groped and squeezed her tits. Andy had his butt clenched and thrust towards my wife's hand manipulation, of his throbbing cock. "Yeah bitch fucking toss me off into your face." He grunted.

Bill, was Slapping his thick ugly cock over her face, he laughed at every slap, as he told her, "You're a bad, bad girl. That's right, you're so fucking bad." ....." I'm just going to have to treat you like the bad girl you are!"..."Like the bad girl you know you are. The bad girl you want to be, the one you've always dreamed of being"

Bill stopped slapping her with his cock, before telling her. "Here bitch, get your head down here... now lick those balls. Be as wet and dirty as you can... yes, yes, that's it."

I was fascinated at this development. Not only was I going to see my wife fucked yet again. I was going to see her gangbanged. The three studs were I was sure, going to give my slut wife, the fucking of her life. I could hardly contain my excitement, my own cock was so hard it was aching, I knew it was as hard as it had ever been, and I couldn't wait to see the guys fuck her senseless.

As I watched the developing scene before me, I stripped off my trousers, underwear and shirt. I could hardly touch my cock or balls for fear of shooting my load prematurely. I just spat on my hand and rubbed the saliva into my shaft to try and ease the ache I was feeling. I left them alone and returned to watch the action in our home gym.

The three guys had by now positioned her at one of the weight benches. Andy was laying down on it his thick hard cock pointing straight up in the air. Anne straddled him and I watched as she lowered herself down onto that big cock. "Aaaaagh yeah, oh my god that feels soooo good." she groaned.

Then Anne started to bounce up and down on Andy's cock. "Yeah....Yeah...Yeah, fuck, fuck me, fuck me!"

Andy held her up by holding onto her tits, as she began pounding herself on his cock, Anne kept grunting on each downward thrust. "You like it when a big cocked strong man fucks you hard don't You?" ...."You just love being with a strong man, don't you?" shouted Andy.

"Oh god yes, yes, I love strong big cocked guys"

Bill, her boss, and Rob her original stud stood at their side, looking on. The two studs were eager to join in and Rob said, "You like being fucked hard don't you. You like it hard... you're such a slut, who likes it hard... you like it when you get fucked hard and rough like this don't you?"

Andy was still fucking her "Tell us you like it hard and rough bitch!" whilst thrusting extra hard up into her cunt.

"YES, I like it HARD and ROUGH!" she eventually squealed.

That was the signal for the other two to join in. As Andy continued shoving his cock into my wife's cunt, Rob entered her asshole, easing into her until only his balls were visible to me from behind where I was hidden. They began a steady build up until; each would reverse the procedure of the other, repeating the whole process over again and again. Each time I would hear Anne, moan with pure lust as these two young studs fucked her brains out. "Uuuuughh...Ohhhhhmph....Uuuuh!"

"Yeah..Bitch... how...do ...you..Like ...that" Rob grunted, one word at a time on each inward thrust to her ass.

Andy was shoving his hips up into her willing abused cunt with equally hard thrusts, "I think she likes it Rob...at least going by the wetness running down my balls she is!"

I could see what he meant. Andy's balls were soaked, dripping and glistening with their combined love juices. Rob on the other hand could be heard making loud squelching sounds with his cock as he ass fucked my wife.

Meanwhile Bill, her boss, was stood off to one side. All the while Bill was rubbing his gnarled, thick veined, cock in anticipation. Then he stepped forward and grabbed her head shoving her face into his groin. "Come on you little slut, suck it!...suck my fucking cock." Then he grabbed his shaft and began feeding it into her mouth, inch by glorious inch. "Come on you little slapper, swallow my cock bitch!"

I watched transfixed as Anne, opened her mouth to allow him to basically fuck her face. By adjusting her head I watched as Bill fed every last inch down my wife's throat. Anne barely gagged once as her nose ended up buried in his pubic hair that was still growing above the shaved ball sac and shaft belonging to her boss. "Oh fuck that feels good, you little slut."

Then he held her head steady as he began a steady pull out then in and out then in until he was fucking her throat, at the same rhythm, as the two guys fucking her other holes. "Yeah guys she fucking loves it eh?" he grunted.

"She sure does boss, a right little cock loving slut this one." Rob replied.

"Wonder if her fucking husband knows what a nympho she is?" Grunted Andy. All three laughed at Andy's question.

I of course did know, and was eagerly watching her continued adultery, with these three studs, without hers, or their knowledge. Her tits were now squashed against Andy's chest, and were being made to rub against him as first Rob thrust her forward, Andy shoved her up and forward, then Bill shoved her back towards Rob. Her nipples were rigid, her areola and nipples were looking red and angry as her sensitive tips were rubbed against the young stud's chest under her.

"Oh my Goood!....Oh my God!..I'm going to cum! I'm going to cum!"Anne's muffled moan could still be heard. Her body began to buck under their combined assault. The three studs never relented, and then I witnessed something I had heard of, but never seen. My wife, bucked one final time, pulled Bill's cock from her mouth and let out a loud yell as she came. She came so hard I could see fluids squirting out of her cunt past the thick shaft of Andy's cock all over the bench and floor.

"Yeah that's it you slut, were going to fuck the arse off you until you beg us to stop!" shouted Bill. I felt my stomach lurch, my balls tightened, and I felt the all too familiar feeling of my pent up lust, shoot out the end of my cock in several strong spurts. My knees felt weak and I almost fell onto the floor, only managing to stop myself more by good fortune than skill.

I looked at the blobs of cum running down into a pool at the base of the door. I made a mental note to clean it up before I left. Returning to watching my wife and her studs, I saw that both Bill and Andy were now standing either side of my wife, who was now sitting reverse cowgirl style on Rod's cock. In her two hands she held the two stud's cocks and was wanking each of them hard, aiming both cocks firmly at her face and open mouth. "Go on boys' cum for me; give me you're cum... Give me that cum, I want to taste it, I love eating cum...Give me it!"

Both guys must have been close, as they moaned and groaned almost constantly until I saw them remove my wife's hands from their cocks and began fisting their own cocks harder and harder until they both groaned loudly almost together. "That's it bitch, keep working that cock."...." I'm going to Cuuuuuuuum Uuuuuurgh!"

It was fucking amazing watching those two cocks explode almost simultaneously. The two cocks started spewing shot after shot of thick gooey cum straight at my wife's face. Anne to her credit made some attempt to catch as much in her mouth as possible. It was, however everywhere, in her hair, on her face, over her chest and tits, she was covered in the stuff. My hips were dry humping, in time to their shots. I was so excited by the sexual tension and arousal I was feeling, I couldn't help myself.

Both Andy and Bill began picking up their clothes, so I picked my own stuff up and retreated back to the relative safety of our upstairs bathroom which overlooked the stairs, front door and hallway. A few minutes later the two guys appeared; Anne followed with Rob, said cheerio to the two of them and arranged to do it again sometime. I was almost surprised at the openness of the arrangement, however I knew that this was the way it would be from now on, and that excited me no ends.

Once the other two had left Rob and Anne made their way to the lounge. I waited a few minutes and exited the toilet. I moved to the balcony corner and peered over. Anne was on her back, Rob was between her legs, and his mouth obviously fastened on her cunt again. "Lick that pussy till I fucking cum on your face!"

"Oh my god, Oh Rob, I can't take it, I can't take it anymore... oh don't stop!.... please don't stop!

"Oh god YESSSSS ...Keep going, suck that clit.....lick that pussy harder..Harder!"

Anne was gone, Rob had her pleading to cum and he kept teasing her to the point of Cumming then stopping until she was screaming at him. "Oh god Rob, you bastard.... oh god, I'm going to come..... I'm coming!...please Rob, don't stop... please let me come?"

Cum she did, all over Rob's face, gushing is how I'd have described it more like. Her ass humped up into his mouth, her left hand fingers found her clit and she diddled herself until she came, yelling at the top of her voice so much I felt concerned our neighbours would hear her. "Aaaaaaaargh...You Bastard....Uuuuuuuurgh.....Arggggggh!"

Rob stood up and shifted her onto the arm of the sofa, like she was a rag doll. Anne's arms and legs hung either side of the sofa arm. Her cunt gaped open, dripping wet. Then Rob lifted her legs onto his shoulders, placing his bloated cock against my wife's cunt he looked into her face. "Your pussy's so wet; I'm going to fill you up with my cock bitch!"

"Fuck me Rob, use me like your filthy little slut!"......"Fuck my pussy, do whatever you want to me......fuck me however you want I need your cock inside me!"

I watched Rob for the next hour and a half fuck my wife every which way. He had her begging for his cock. He had her pleading to make her cum again and again. He had her laid on her belly over the back of the sofa, he placed her on the coffee table on all fours, where my wife begged and begged him. "Fuck me harder, fuck me faster, and make my tits bounce! you fucker"....."Fuck my cunt till I tell you to stop! You big cocked bastard!"

Rob drilled my slut of a wife, like his life depended on it. I could only imagine fucking my wife so long, so hard, so often, and yet here he was, listening to my cock hungry wife plead with him."Go on Rob, baby, my stud ...Fill me up with cum, fill your filthy worthless whore with CUUUUUUUM!"

Rob obliged her request several times throughout the night. I had needed to leave them, my poor abused cock couldn't take any more. I retreated to the guest room, where I called her to tell her I was delayed and wouldn't get back till the early hours. I said I would sleep in the quest room so I didn't wake her and would see her in the morning. It was obvious that whilst I was talking to her that Rod was either screwing her or playing with her pussy as she let out several gasps which I chose to ignore.

An hour after I called the two of them went to her bedroom, our bedroom and continued their sex session in our marital bed. I could hear her moans and groans until almost three am. I fell asleep, with a sore cock and aching balls, desperate for more of the same, sooner rather than later. I was well into my cuckolding lifestyle and could only see it becoming more of the same ahead.

This story is not meant to be about love, neither is it meant to be recommending a type of lifestyle; it is a story that is it.
