Deep down inside I knew something was wrong, but being married for just five years I thought it was me. I thought if it was something with Mandy, then it had to be a smooth taking guy, you know the kind ladies call the “bad boy” type, and the kind that only wants sex. There were a lot of those type guys in the big office where she worked, and most were very well paid corporate executives, the kind that like good looking, young sexy private secretaries. My young wife has a sexy looking ass, modest but nice breasts, a very small waist, and a sweet sexy voice. Sex had started to slow down around the home front, but then I thought I was the one with the large sex drive. Mandy was occasionally working late because she had gotten an unexpected promotion and maybe she was just too tired after she got home so late. So I thought I would cruse the local spots during lunch time and maybe, just maybe, I might spot an old girlfriend. I was starting to think about straying, maybe a little sex on the side.

To my surprise I saw them sitting in one of the back booths, seeming to be having a drink and chatting. I slowly walked over, sat down on the opposite side of the booth. “How about I buy the next round of drinks”, I said. Jack was a rather well built guy, handsome looking, in his early 30’s, and a smooth talker with a well know repudiation for being a skirt chaser. As we had a few more round of drinks, Jack never looked tense, but Mandy was really nervous, I could tell by the way she was guzzling her drinks. “Look” I said, “I am not upset, not mad, and I understand that friends can be friends, and sometimes they are even more than friends.” With this being said, Jack started moving closer to Mandy and she giggled a little bit but she did not push him away. They began openly flirting and soon, much to my surprise, my very conservative wife was groping Jack’s crotch. Jack looked at me directly and said, “I want to fuck your wife this afternoon Dave, and I think she would like me to.” After five years of marriage, I was about to watch my wife have sex with another man, I was getting turned on and this was about to become a reality right in front of my eyes.

I guess I didn’t expect it to happen so fast, but at least it was happening with someone I knew was not interested in taking my wife away, Jack was just interested in fucking a very beautiful, sexy looking 23 year old lady with super looking ass. I looked at Mandy anxiously to see what she wanted to do. Mandy kind of laughed and said “Sure, why not.” Jack returned to openly kissing my lovely wife of 3 years and I was completely dumbfounded, she was going to do it. Mandy looked disheveled at me and began giggling.

Little did I know that Mandy already knew what to expect, for this was not the first time that Mandy and Jack had been together. All this started a year or so back when Fay told Mandy, “He is big in that department”, and this was something that Mandy just could not get over, the thought of really trying out a “big dick.” The alcohol had gotten to her. Jack got up and Mandy slid out behind him with her short skirt rising up. I could see that her panties were slid to one side. Jack must have been fingering her the whole time I had been sitting in the booth. My balls began to churn as Mandy bent over and kissed me. She whispered in my ear, you should have felt what I felt in his pants and she wickedly smiled at me as Jack took her by the hand and I followed them like a scolded puppy dog out of the bar and drove them back to our small house.

In our bedroom they stood next to the bed, and I took a seat in the chair so I could watch. They wasted no time and began undressing; Jack pulled off her blouse and skirt to reveal her panties. I could see the crotch of her panties were soaking wet, she was really excited. I began to feel at ease as she looked at me and smiled. Mandy stripped Jack down to his underwear, and I could see that his cock was already up and ready for the job. Mandy got down on her knees and slipped the waistband of his underwear over the head of his dick. She again looked at me and then took a few tentative licks. She lowered his underwear to his ankles, and he stepped free of them. Wrapping both hand around Jack’s ever swelling cock, Mandy began gently rubbed the head of his 10 inch cock over her lips, just giving little licks and kisses up and down the entire length of Jack’s cock, making his pre-cum start to slowly drip from the enormous purplish head. She looked up from her knees and began talking baby girl talk to him, “Mmmm, you taste so good Jack, and your cock is nice, big and so hot. Its making my pussy so hot, did you see how wet my panties are?”

“They looked really wet, let’s see you without them.” he replied. I could not believe my conservative little wife of five years was being such a slut for this man. Straining to open her tiny mouth wider, Mandy began to slowly inch Jack’s 10 inch cock into her dripping mouth as she managed to get about 6 inches of the massive cock in her mouth. Jack stepped back pulling his massive cock out of Mandy’s mouth with a popping sound, lifted Mandy to her trembling feet and leaning over to slowly run his tongue around the hard nipple of her breast.

Jack reached down and felt her wetness, and then told her to lie down on the bed and spread her legs. Mandy obeyed; Jack climbed between them and began eating her out. I watched fascinated, as this was one of my favorite things to do. Mandy gasped as his tongue slid up and down her labia, and then slid in and out of her pussy. This went on for some time, he would suck and lick her clit, and then tongue fucks her. My cock was now aching, and the confinement in my pants wasn’t helping any. I’m so hot, please give it to me now Jack, Mandy moaned “Fuck my hot pussy, make me cum”. I just shook my head as I watched thinking who was this woman? I had never seen her in such a passionate state.

Jack needed no extra urging, pushing Mandy’s bent legs up until her knees were pressed against her breasts, and he began to mount her as I watched. Mandy had her legs spread wide, and Jack opened his so that I could clearly see as he guided the tip of his 10 inch cock to Mandy’s waiting slit. Jack rubbed the massive head of his cock up and down the tiny, wet slit, and began to ease the head in, and Mandy moaned loudly. Jack slowly began to insert more and more cock into her wetness, slowly withdrawing and then inserting another inch or so until I watched his entire 10 inch cock disappear into her eager pussy lips and then slowly slide his thick prick out again causing her to go into a frenzy trying to fuck him back. He continued, sometimes increasing pace to a hard and fast fuck, and then backing off to a slow gentle pace.

Mandy was grabbing and pulling at the sheets on the bed, moaning with ecstasy and pressing her pussy back up trying to get even more of Jack’s 10 inch cock stuffed into her dripping pussy. As I watched all of this, my cock had soaked through my underwear and there was a visible wet spot growing on my pants. As I viewed the spectacle Mandy suddenly shouted “Oh Fuck I’m going to cum! Yes Jack; Yes give it to me hard I’m Cumming on your big cock!” I knew at the moment things would never be the same in our lives.

She started to writhe beneath him as he rammed his cock deeply into her. Harder and harder he pounded her wet pussy as Mandy cried out with another orgasm. I saw his ass clench and his balls draw up right in front of my eyes. I could see him grinding into her deeply and she was pushing back just as hard. Oh, I thought to myself this man is pumping his cum deep into my wife’s pussy. In all the excitement I had never even thought about a condom. Obviously Mandy didn’t either. Jack collapsed on top of her spent from the force of his ejaculation. I could see the cum on the base of his shaft buried deep inside my wife. He laid there for about a minute, cum slowly seeping out as the massive cock began to slowly deflate, then Jack pulled out of her. His cock was limp, and wet with their juices, and as he pulled away a string of cum hung from his dick to her pussy. Mandy laughed and said “We are so wet, just wipe that big 10 inch cock off on my pussy please”. Jack smiled and rubbed his cock up and down her cunt, leaving the drippings spread all over her pussy lips, and then rolled off of her and lay next to her.

Mandy rose up on her elbows and viewed the sticky wet mess of her crotch. She smiled and looked at me. “Do you like what you see babe?” She asked. I looked at Mandy and said jokingly, as I stared at her pussy and I definitely liked what I saw, I was really turned on and I had a thought in the back of my mind that I might like to eat her out. I couldn’t believe I wanted that, but I hadn’t cum and right there in front of me was my wife’s beautiful cunt all filled up with cum, my fantasy come true. It wasn’t my cum, but God I was hot at that point.

I saw that Jack’s cock was at rock hard again, and Mandy noticed also. She got on all fours and presented herself to him. Jack took the hint and positioned himself behind her, and promptly buried his cock inside her. Mandy started to rock back and forth, impaling herself deeply with each stroke. Her eyes were fluttering; she had become possessed just as I was and I wanted her to be. Jack was a stud that I never was. I could never give her cock like he was and for some reason I was OK with all of this. I didn’t have to pretend anymore, now we all knew that this was just sex, and nothing more. I really didn’t care if she was fucking Jack because I knew she was mine and I loved her even more.

Mandy looked up at me and said “Sweetie, climb under me and lick me while I’m getting fucked, please, Don’t think about it, just do it, I want you to do it so fucking bad, please lick my cunt now!” I wanted to please her so I got underneath her and she and Jack spread their legs a little more to allow me easy access. From that angle I had a great view of his thick 10 inch cock going in and out her wet lips, and Mandy’s pussy was actually working up into lather. I reached out with my tongue and started to lick her clit gently.

“Oh fuck yeah!” She shouted. “Lick me hard you nasty boy! Lick my clit, oh yeah Jack fuck me deep!” I started to lick at the hole as she ordered me, sliding my tongue over the clit and around the hole just as she was getting pumped by Jack’s big 10 inch cock. My dick was spewing all over my stomach. Mandy began to spasm wildly, and Jack grabbed her hips to keep his cock buried deep in her. She cried out that she was cumming again, and her body began to quiver as she rode out her orgasm. I was watching Jack’s balls and I saw them tighten up as he dumped another load into Mandy, and she sobbed with pleasure feeling her pussy fill up again with another man’s cum.

Jack pulled out, and Mandy dropped herself straight down onto my face, cum leaking freely from her gaping hole. I lapped it up as she grinded down onto me. I sucked hard as she leaned forward and took my dick into her mouth. I lasted about 10 seconds, and then a violent orgasm shook my whole body as I let loose what felt like a gallon of cum into her mouth. She continued to suck and I continued to lick until my cock began to deflate. Finally, she rolled off and turned over to face me. I had cum on my lips and face, and she had a big smile on hers. Jack was watching as she grabbed me and kissed me hard. I opened my mouth to accept her tongue, and was surprised when she returned my whole load of cum to me!

“Now swallow that one too” she said with a grin. I smiled and let it slide down my throat, and she let out a laugh. “There, now you finally got to taste your own cum lover, maybe next time you will actually be able to eat it from my pussy! If not, we can always invite Jack back for more practice.”

After Jack left we made love like we have never made love before. Mandy has had Jack back over a few times since then, but that afternoon was the best.
