I looked over at my wife Mary of nearly 20 years as I was driving. She looked good. We were heading to an annual Christmas party being held my long-time friends of ours which we almost always attended.

She was wearing a green dress which was sexy but not slutty and black high heels which accentuated her calves and her perfume smelled great. I reached over and slid my hand up her thigh which started causing her dress to lift up her leg. She giggled, stopped my hand, flipped it over and held my hand.

“You can’t get me all steamy before the party,” she said.

Inwardly, I sighed as I kept driving. Par for the course. We had a good life, in our late 40s, great kids and I made a very comfortable living. I should have been content (I often wondered if content was a synonym for bored out of your skull). Mary has always been an amazing wife and great mom to our two kids, but her sex drive was low to non-existent these days due to a medical issue. Nowadays, when we did have sex, it was ok but very vanilla and bereft of passion. If you are always the one who initiates, after a while, it weighs on you, making you feel unattractive and lacking in capacity to make your partner’s animalistic urges come out.

We arrived at the party and began to mingle, Mary having gone off to the living room to chat with her friends while I was in the kitchen chatting it up and refilling my wine glass. That was when I looked over and saw Elaine arrive with her boyfriend Alan.

Elaine was the daughter of some acquaintances of ours (Dana and Tim) who were also at the party. We had just gotten to know them in the last few years through mutual friends. She was in her mid twenties and a stunner. Gorgeous, with shoulder length blonde hair, perfect ass and solid B cup breasts and a smile which would light up a room. She was wearing a red top and tight jeans and looked amazing. I had not seen her for a few years as she had moved away for work and to be with her boyfriend Alan. Mary had told me they had moved back in with Dana and Tim to save money for eventual marriage and buying a house.

She passed by me on the way to the refrigerator to put away their beers and stopped to say hello to me.

“Mr. Massey! So good to see you, you look great as always,” she said with a wide smile that nearly melted me.

She gave me a tight hug, and I felt her tits press into me. Was I imagining it, or was her hug just a little too long? Maybe just the wine getting to me.

“Always great to see you Elaine,” I managed to stammer.

As I had returned the hug and had my hands on her back, I didn’t feel a bra clasp which told me it was a front snap bra. Sexy. I had to break the hug before my cock got hard.

As the night progressed and the wine flowed, I found myself staring intently at her more and more. I couldn’t help it, that hug made me feel attractive and wanted again, even if just an innocent (?) hug by her. At times, I felt like she knew I was looking and thought I saw a mischievous twinkle in her eye. I sighed, wishful thinking and wine.

It was late and people were beginning to leave here and there. I was standing in the kitchen again, my back to the counter leaning against it. Mary was close by talking with someone else. It looked like Elaine and Alan were getting ready to leave. He had gone out to warm the car up. She was in the foyer with her back to me and due to the angle, I was only one who could see her. As I was, once again, admiring her ass, she dropped the present she had gotten in the Yankee swap. She squatted down to pick it up causing her shirt to untuck and revealing she was wearing a red thong. Based on seeing a bra strap earlier when her top had shifted, she was wearing a matching bra and thong. Sexy as fuck. Her head snapped around and I was for sure caught admiring her thong and ass. I started to look everywhere else but at her.

She came back into the kitchen to finish saying her goodbyes. She said bye to Mary, giving her a hug and a few other people. She got to me.

“Merry Christmas Mr. Massey,” she said in her bubbly fashion.

“Please, I told you, Mr. Massey is my father, call me John,” I said jokingly.

She laughed and said, “OK, John.”

She moved in to hug me. The hug was again tight, I felt her breath in my left ear and she whispered in my ear, the bubbly voice gone.

“I saw the way you looked at me just now and all night for that matter,” she whispered in a low husky voice.

I froze. Was she going to make a scene? Was she going to tell Mary how I was checking her out all night?

She pulled her head back and the bubbly voice returned as she said loudly, “And Happy New Year.”

Her head came back in to my right side this time and the low whisper returned.

“It made my pussy soaking wet when you did. I can’t wait to get home and think of you while Alan is pounding my pussy,” she growled.

I was speechless . She had always seemed like a prim and proper young woman. I couldn’t believe what I just heard.

Elaine finished her good byes and left without looking at me again. Mary and I left soon after.

Mary drove as I had drunk too much wine. She was chatting about the party and how fun it was seeing everyone. I responded as required, but my mind was a million miles away.

Mary went to bed almost immediately when we got home, I told her I was going to watch TV for a while. I jerked off and had the best orgasm I'd had in a long while, shooting ropes of cum everywhere while thinking of fucking and doing things to Elaine that Mary would never try. I would normally clean myself off before getting into bed with Mary, but this time I didn’t. I don’t know why, but it felt hot knowing I was laying next to her with cum on me from jerking off thinking about Elaine. She was fast asleep. Par for the course.

As I drifted off, I was thinking if and how I could fuck Elaine. There was a strange mixture of emotions, unbridled passion and overwhelming guilt of even thinking such thoughts. Would guilt and fidelity win out? I would get the answer soon enough and the answer was no.

Two weeks later, on a cold and windy day, I was working from home. Mary asked me to swing by Dana and Tim’s house around lunch time to pick up a bunch of old clothes that Mary was putting together to donate to a local shelter.

“Aren’t they both working?” I asked.

“They are, but Elaine is off today and at home. I already talked to her. When you get there, back into the driveway and beep the horn. She will open the garage door so you can back right in and keep you both out of the cold wind,” Mary replied.

“Ok cool,” I said, trying to sound nonchalant and annoyed at having to go out. Inside, my heart was already racing. Would Elaine mention the Christmas party? Would I have it in me to become unfaithful to my wife and make some kind of move on Elaine if the situation presented itself? I felt alive.

As arranged, I backed into the garage and the door closed. I took a deep breathe and got out of our SUV and Elaine was standing there in a white t-shirt and what looked to be yoga pants. While the garage kept us out of the wind, it was still quite cold and I could immediately see she was not wearing a bra as her stiff nipples seemed like they wanted to drill through her t-shirt. She made no attempt at modesty to cover them with her arms. She’s teasing me, I thought. My cock began to stir.

“Hi Mr. Mass… um John, the boxes are right over there,” she said, pointing to the other side of the garage. “I’ll help you, it won’t take long.”

“Hi Elaine, great, appreciate the help,” I managed to mutter. I was in a fog and don’t remember if I ever stopped looking at her nipples or not.

It was short work and done quickly. As she lifted the last box into the back of the SUV, she pushed it all the way forward causing her to bend completely at the waist. The yoga pants hid nothing and I could see she was again wearing a thong.

Without turning around she said, “I told you my pussy gets soaking wet when you look at me like that.”

My cock was instantly hard. Excitement and guilt was a curious mixture. Excitement won out and I decided to cross the first of many lines that day. She straightened up and turned to face me.

“And my cock is hard seeing you like that,” I said trying to feign confidence.

She grabbed the noticeable bulge in my pants. I am just a bit longer than average but have a good girth that Mary and all the women before her had enjoyed.

Elaine smiled as she rubbed my bulge.

“Good,” she said in that low sexy voice that I had jerked off too multiple times since the Christmas party. “Come on in and I’ll make us some coffee to shake off the cold.”

With that, she turned and started heading toward the door back into the house.

This was it. The moment of truth. Should I follow her in and succumb to desire or apologize, leave and be true to my vows with Mary? My mind whirled, again the curious mixture of guilt and excitement. Indecision. One thing for sure, my cock was so hard it could chip the ice on the walkway out front.

I think she could sense my indecision. She turned around and asked with a smile, “Are you coming?”

She slid her hands up, starting at her belly and ending on her hard nipples, giving them a pinch.

Lust and blind sexual energy took over. Fuck taking a par, time for a birdie.

“You’re damn right I am,” I stated with now complete confidence and strode toward her, locking my eyes with hers.

“Good,” she replied with a voice and smile that exuded sexiness.

We walked into the house, which I was familiar with as Mary and I had visited Dana and Tim on a few occasions. I followed her into the kitchen and naively assumed we would stop there and the promised coffee or something would happen, but she kept walking down the hall to where I knew the bedrooms were located. I followed, my cock now aching.

After we entered, she stopped quickly, which made me bump into her from behind, my hands instinctively landing on her hips. She immediately put her hands on top of mine and guided them under her shirt and up her belly till at last I felt her hard nipples. She let out a soft moan.

She said, “I love older guys and have wanted to fuck you since we first met. I get turned on so much by wanting and taking what I can’t have.”

She let out a loud moan as I pinched one of her nipples while I bit one of her earlobes at the same time. Still behind her, I lifted her t-shirt over her head and let it drop. My hand slid down her tight belly and dove immediately under her yoga pants and panties till I reached her clean shaven pussy. I could feel on the back of my hand that her panties were soaked. This was further confirmed as my fingers finally found her folds. She was soaked.

“I am always a slut for Alan,” she gasped as my finger plunged into her pussy. “And now, apparently, I’m your slut too. I always thought you were hot for an older guy. I’ve fingered myself plenty of times after parties and the family functions we both attend while thinking of you. And as promised, after the Christmas party, I was thinking of you while Alan was pounding me. I had the biggest orgasm of my life when he came in me while I was thinking of you.”

As she said that my fingers found her swollen clit and I pressed hard on it while nibbling her neck. She whimpered and began rubbing her ass on my bulging jeans.

“And I always thought you were a good girl,” I whispered in her ear. My fingers continued to slide around her clit.

“I am,” she replied in a quavering voice. “I’m a good daughter to my parents, I’m a good girlfriend to Alan, I am kind to strangers and animals. I am a good person, I just love sex and having what I’m not supposed to.”

She reached down into her pants and placed her hand on top of mine and began helping me with her clit.

“Fuck that feels good,” she whimpered as I continued to rub her clit from behind with my left hand, cupping one tit then the other with my right, pinching and rolling a nipple occasionally and nibbling her neck and ears.

“Rub my clit with your wedding band,” she growled.

Fuck, that turned me on more than I would have thought. As I began gliding my ring over her clit, she started panting. I could sense she was close to cumming.

“You are a naughty little slut, aren’t you?” I growled in her ear. “Whose naughty slut are you?”

“Yours! I…want…to know…the next time…I see you... and Mary that…uuummm your ring… was on my clit...fuck!…and covered in… my pussy juice...fuck fuck…don’t stop… I’m cumming!”

As she said that I pressed down hard on her clit with my ring and pinched a nipple maybe a bit too hard. She gasped, I could feel her body contorting. Her legs got wobbly, forcing my hand off her nipple to her waist to steady her as she came.

Once she steadied herself, she turned around to finally face me.

“Fuck that was amazing,” she purred. “Now it’s your turn.”

She grabbed my left hand and brought it up to her mouth and sucked my ring finger all the way into her mouth, keeping eye contact with me the whole time.

“I love to taste myself,” she said as she began unbuttoning my pants. “I need this married cock in my mouth.”

Fuck, she was driving me crazy.

“Then take it you naughty slut,” I said while I grabbed her face. We then kissed like mad lovers, our tongues swirling around each other, she playfully bit my lip

She quickly stripped me down; as she pulled my boxers down, my aching cock finally sprang free. I pulled her yoga pants down and she stepped out of them, leaving her only in her black thong.

“Oh, your cock is as good as I have imagined, nice and thick,” she quietly said as she started stroking it between us.

She led me over to the bed and quickly jumped on all fours and flipped around, her face at my cock, her thonged ass wiggling with me standing at the edge of the bed.

She started by swirling her tongue slowly over my head and then licking fully down my shaft and up again.

“Does Mary suck a good dick?” she asked.

I winced a bit when she said Mary’s name, guilt again surfacing.

“She used to be ok,” I managed to moan as she continued swirling her tongue slowly around the head of my cock. “She doesn’t do it at all anymore.”

“That’s what I thought,” she whispered and slowly took me fully into her mouth. Though she just touched the back of her throat with me, I sensed she was holding back.

“Fuck!” I groaned as she kept swaying back and forth on all fours taking my cock in and out of her mouth. I watched her beautiful ass in the thong as she did so. She changed positions and sat at the end of the bed in front of me, her legs touching the floor. She began to use her hand in concert with her mouth, twisting her hand as she got to the head.

My phone rang and it was the ring tone I had set for Mary. I froze. Guilt crashed down on me.

Elaine took my cock out of her mouth but kept stroking my dick.

She said in a devilish voice, “Answer it. It’s Mary isn’t it? Put it on speaker, I want to hear her.”

She took me deep again into her mouth, this time definitely touching her throat but not going past it.

I tried to keep my voice steady as I said, “Hi baby, um I got you on speaker. Elaine wanted to say hi. We just finished loading everything.”

Elaine took my cock out of her mouth quietly and said, “Hi Mary,” in her bubbly voice and then took me deep again.

Mary’s voice coming over the speaker said, “Hi sweetie, please thank your parents again for the donation.”

She pulled me out of her mouth again but kept stroking my dick. I could tell this whole exchange was really turning Elaine on as I saw her other hand dive into her panties to rub her clit. She really got off on being or almost being caught.

“Will do, Mary,” she said in her bubbly voice, then took me deep in her mouth again and quickly out. “Oh I’m sending John home with something.” I froze. She quickly took me deep again and back out. “I made a batch of cookies, oatmeal raisin.”

“Aw, thank you, that’s lovely. John, can you stop by the dry cleaning place on your way back and pick up our order?” Mary asked, oblivious to the fact her man’s dick was in this girl’s mouth.

“Will do,” I said.

Mary replied, “Ok thanks, love you.”

The moment Mary said “love you”, Elaine fully plunged my cock all the way into her throat. I felt my cock head pop fully into her throat and her nose was fully pressed against me. She kept eye contact with me the whole time. Her eyes rolled back and I could tell she was cumming from her furious work on her clit and the erotic nature of the situation.

“Love you baby,” I managed to croak and hung up. The guilt washed away as I had never been turned on so much, the last years of sexual neglect being satisfied finally. I needed to feel her pussy.

“You are a naughty dirty little slut and now I’m going to fuck you like a naughty dirty slut deserves. What side of the bed does Alan sleep on?!” I demanded. I was fully lost now.

She pointed. I tossed her to that spot and got her on all fours again, her thong staring at me as I was standing next to the bed. I moved her thong to the side.

“Put your face down into the mattress where he sleeps and beg me to fuck you,” I demanded. I was a new person. I had never been involved in a more erotic and shameful situation.

She complied and put her face down, turning her head to the side while keeping her ass in the air.

She said in a pleading voice, “Please John, stick that fat married cock in my slutty pussy. Please fuck me. I’m begging you!” I could tell she had already started playing with her clit as she was begging.

I slammed my cock as hard and fast into her as I could and didn’t stop. I kept jackhammering my cock into her. She had an amazing tight young pussy but was completely drenched so my cock slid effortlessly.

She wailed, "God yes, fuck my slutty pussy, let me feel what Mary takes for granted and doesn’t want anymore!”

I smacked her ass cheek hard and blurted, “Fuck! Your pussy is better than Mary’s.”

That was enough for her, what she wanted to hear. I could feel her pussy clamp down hard on my cock and her whole body seemed to tremble as she yelled.

I slowed a bit to let her recover, then started pounding again. I could feel myself getting close.

“I’m gonna cum, Elaine, where do you want it?” I asked.

She quickly spun around on the bed, seating herself on it and began stroking my cock which was right in her face.

“I want your cum in my mouth. The next time I hug and kiss Mary on the cheek, I want it to be our dirty secret that your cum was on my lips,” she said seductively.

She took my cock to the hilt again, her eyes intently watching me as my eyes rolled back as I began to shoot rope after rope of my hot cum into her willing throat. She let the last spurt hit her face around her lips and nose. My knees buckled and I could barely stand.

She got up and kissed me deeply, our tongues feeling again, tasting my cum in her mouth.

After we had cleaned up, she handed me the plate of cookies she promised.

My guilt was coming back. What had I done? I couldn’t, however, deny a sense of exhilaration and reforged passion.

“I do love Mary and will never leave her, but thank you for the most incredible sex I have ever had,” I stated bluntly.

Elaine smiled. "I know you love her. I love Alan as well. I just had to have you. Don’t ask why, I don’t know myself, other than I like being naughty.”

I was glad we got that out of the way.

I didn’t see Elaine again till the summer. The same couple who hosted the Christmas party also hosted a Fourth of July party.

Mary and I had just arrived and were walking into the backyard where everyone was gathered, and we started with our hellos. I spotted Elaine and my cock started stirring. When we got to her, Elaine gave Mary a kiss on the cheek and hugged her.

Mary’s back was to me. I could fully see Elaine’s face, remembering what she had said about giving Mary a kiss. I held up my left hand and wiggled my ring finger that had been all over her clit.

Elaine mouthed the words to me, “I’m so wet,” and gave me a devilish smile.
