My Sister’s Husband – Part 1 [MF] [Cheating]

Christmas with my family reminded me in no uncertain terms that I am still a slut. Always have been and probably always will be. Once again I allowed myself to scratch a very old itch and let my brother-in-law Mike fuck me. We aren’t together very often but when we get the chance, he always seems to find some way to get me to do whatever he wants.

Before I tell the story of what happened during my Christmas visit, though, I thought it would be fun to share how it all started over 20 years ago and then share a few of our hottest encounters when I get some time. The latest was one of our hottest-ever so it will definitely be getting its own post. It’s still burning bright in my memory and has me slippery wet as I sit here typing this.

The first time anything ever happened between us I was 27 (I’m 49 now) and had been divorced for about six months. I desperately needed to get away from the small town where both I and my ex-husband still lived. I would occasionally run into him and his new girlfriend around town and it was starting to wear on my nerves.

I had mentioned to my sister Deanna, who is two years older than me, that I wished I could come out to visit her but there was no way I could swing the cost of the plane tickets and she said she’d love to see me too and would see what she could do. Honestly, I never expected anything to come of it until I got the call the next day that she and Mike would pay for me to come out. I was ecstatic and couldn’t wait to go. I had only been to San Diego once when she had gotten married and hadn’t been able to see much of the city or even go to the beach.

The trip was only going to last for four days but to me, it was exactly the break I needed. I still remember singing loudly and happily to myself in my tiny studio apartment as I packed my bags.

When I bounded off of the plane I was a little surprised to see only Mike waiting for me. He was looking handsome as he always did, with that friendly smile on his face that he always had. When he caught sight of me his smile turned into a grin and he waved. I waved back and hurried over to him and we shared a really quick hug to say hello.

I asked where Deanna was and he explained that she was stuck at work and couldn’t make it but would be home later. That was fine and we started off toward the baggage claim.

We arrived home and got settled in on the couch where we started catching up. Normally I only talked to Deanna when I called so talking to Mike alone was nice. We chatted for probably an hour before the conversation made its way to relationships. He asked how I’d been holding up after the divorce and I tried my best to keep up a strong front but I’d had a really long day and at that moment I was emotionally drained. Out of nowhere, tears began streaming down my cheeks and I put my face into my hands and began sobbing.

He didn’t really know what to do and said really softly, “Oh fuck, what did I say?”

I shook my head and tried to tell him that he didn’t say anything wrong but all that happened was I started crying harder. I felt him move in next to me and wrap his arms around me. He didn’t say another word and just held me tight as all of my pent-up emotions came streaming out of me.

I don’t know how long we sat there in that embrace but it was long enough for me to realize just how much I had been missing the touch of a man. I finally sniffled and took my hands away from my face and wrapped them around him and pulled him in even tighter. I whispered in his ear through the tears that I felt like I wasn’t worth loving again.

He kind of laughed at that, not in a mocking way at all but very supportive. He very softly said that I was definitely worth loving and that I would find another man. I just needed time, he said.

I could feel his slightly scruffy cheek pressing against mine and it felt amazing. I could feel his chest expanding as he slowly took in breaths. I could smell his faintly sweaty scent and knew that at some level that I was becoming aroused.

I sniffled and pulled back and he looked down into my eyes. He smiled and told me that my makeup was all messed up and stood up and brought back a warm wet washcloth and helped me wash off my face. It was one of the sweetest things I can remember a man ever doing for me. My ex-husband had certainly never done anything like this and I found myself even more turned on.

When he got finished he said, “There we go; beautiful as always.”

I blinked in surprise and asked him if he really thought I was beautiful and he looked at me like I was crazy and said, “Stacey, you’re fucking gorgeous and you know it.”

I had to laugh at that and felt myself deeply blush. My face was hot and I just kept smiling. I couldn’t think of what to say next and just melted back in his arms again.

He held me for a while longer and I was having quite an internal battle. I kept telling myself that this was my sister’s husband and that if I crossed this line I could never come back from it. There was this small voice though that kept reminding me of how long it had been since I’d been this close to a man and how long it’d been since I’d had sex, and that small voice kept getting louder and louder until something broke within me.

I made a snap decision and within seconds my lips were on his. He moaned loudly into my mouth and started pulling back. He said all the things you would expect him to. ‘We can’t do this.’ ‘It’s not right.’

I knew full well that it wasn’t right, but at that moment I was feeling especially selfish and was going to get what I wanted. I could already see how hard his cock was through his pants and ran my fingers over it, causing him to shudder and softly moan.

I said very softly, “It’s been so long. Don’t you wanna fuck me? Please, I need you. Just this once.” My fingers continued to work on his cock and I could slowly see the conflict in his expression turn to lust.

It only took a few brief moments until something snapped within him as well. We passionately kissed and his strong hands were all over me. He pushed me back and I let him undress me completely. He stood to get rid of his own clothes and I quickly knelt before him and undid his belt and got his pants down and just like that I had his cock out. It was gorgeous, with just a slight bend upwards and nice and thick. He kept everything nice and trimmed and I could see that his balls were shaved completely smooth, which to me was perfect.

His tip was already wet with precum and I wasted no time in taking a hold of him and licking it up. I’m a complete cum slut and wanted his cum in my mouth, or in my pussy and then in my mouth. Either way, I wanted to taste him. I needed it. I needed *him*.

I took him as deep in my mouth as I could and tried not to gag. It had been quite some time since I’d had a dick in my mouth and I was out of practice. It didn’t take long for me to get back into a rhythm, though. I love slow, deep and sensual blowjobs where I only use my mouth, and I could tell from his expression and sounds that he was liking what I was doing.

I ran my hands up his body as I lovingly sucked him and before long I could feel him start to buck and he hissed that he was close and when he could see I wasn’t stopping he just put his head back and growled like an animal and filled my mouth with cum. The first few spurts surprised me due to the force with which they erupted from him but I’m a good girl and never allowed even a drop to escape. I kept swirling my tongue against his sensitive spot and swallowing his warmth until he exhaled heavily and made a whimpering sound. I continued sucking the tip until he pushed me away. I had nearly had an orgasm without even touching myself as he came, something that had never happened before.

He collapsed down on the couch and I noticed that his cock had barely softened at all. I wasn’t about to stop there because I needed him inside me badly. I got up from the floor and straddled his lap and guided him in.

He groaned as I shuddered and lowered myself all the way down until he was fully inside me. I had to take it slow since he was quite a bit thicker than my ex-husband and I hadn’t had sex in almost a year. The pain I felt was brief though and I quickly adjusted. After a few deep cleansing breaths, I began rocking on him.

The slow rocking didn’t last very long. He reached down under me and started lifting me up and really fucking me hard. My first orgasm was kind of a small one, but it happened much quicker than usual and I knew stronger ones were on the way. The next orgasm hit me like a truck, causing me to cry out loudly. Mike was relentless and kept fucking that thick cock of his into me and making me come again and again.

I breathlessly begged him to come inside me and that was all the permission he needed and pounded me even harder until he suddenly grabbed me and pulled me tightly into him and growled that sexy growl of his and emptied himself deep inside me.

Just for a little longer he very slowly continued thrusting into me as his orgasm subsided. I leaned into him and we held each other in the tightest embrace as our heavy breathing slowly returned to normal. We kissed for several minutes and explored each other’s mouths lovingly.

I could already feel his cum starting to drip out of me and I whispered that we should go get cleaned up so we didn’t make a mess on the couch or the floor. He was very quiet and nodded in agreement.

I raised up off of him and held my hand over myself to stop any leakage, but I wasn’t quite done yet. I looked down into his eyes and raised my hand to my lips and licked my fingers. When I put my hand back down between my legs and brought more of our juices to my lips, he smiled and his cock twitched in excitement.

I knelt and licked him clean and sucked him again enough to get the last little bit and swallowed it. I told him how good we tasted together and he said we needed to hurry since Deanna would be home really soon.

We got up and quickly showered together just before she got home. We both managed to not act out of the ordinary and never raised any suspicions. Other than a few knowing glances, nothing else happened during that visit because we couldn’t find any time alone. I did manage to do some shopping with Deanna and finally got to see the Pacific ocean. I’ll never forget the sound of the wind and waves and how incredibly peaceful I felt while lying on the beach.

This was only the beginning of my 20+ year affair with my brother-in-law.

  1. I have a thing for my sister-in-law and kept reading this in her voice. So damn hot. Thanks for sharing!

  2. There is something about forbidden fruit that makes it so hot. I was once very attracted to my SO sister but I could never cheat on anyone I love. So I’ll just live vicariously through your story. Can’t wait for the next one.

  3. That was amazing and extraordinarily hot. I would love to see the rest when you write them. Very well written.

  4. Very hot story. Did you ever remarry? Does your significant other know about your relationship?
