My girlfriend’s brother-in-law [MM]

We have known each other for a few years, seeing each other at holiday family gatherings ever since I got with your wife’s sister. You’re a good looking guy, 5’8” with a slim build but some muscles that tell me you know how to find the gym. I have four inches and at least forty pounds on you, as the quarantine lifestyle has left me with a slight dad bod. I am broad shouldered and bearded, and my big thick cock with heavy balls has kept me popular with my girlfriend and the guys on Grindr I use when I need my cock drained.

I have wondered about you ever since I met you. I have caught your eyes lingering on my bulge from time to time, but we see each other so rarely and we’re never alone together, I have not had the chance to test the waters.

My questions about you were answered this year at the thanksgiving family gathering, as your wife and my girlfriend arranged for us to spend the holiday just the four of us in a Airbnb cabin in the mountains. Their 60-something-year-old parents were not hosting this year out of concern for COVID, and the girls thought this would be a good compromise.

We arrived at the cabin Wednesday night and you two were already there. The four of us caught up and talked well into the night, until exhaustion sent us to our separate rooms and we retired for the night. My girl was bubbly and excited from seeing her sister after almost a year apart, but with it being after midnight she was asleep as soon as her head hit the pillow. Being more of a night owl myself, I still had some oil to burn. I pulled up my phone and started browsing my favorite erotic story subreddits, when on a whim I decided to check the local scene on Grindr.

My Grindr profile is simple and to the point. It makes it clear who I’m am and what I am looking for: a thick hung masculine man who’s looking for subby cocksuckers who know what they’re doing. I liked to use the app while traveling, but I found that rural areas were usually slim pickings, but it never hurt to look.

I was in for quite a surprise when I opened the app, as usual for small towns most of the people were over ten miles away. But there was one profile that was close. Really close. It listed our distance as 20 feet from each other. My heart raced as I opened the profile page. The display name was the tongue emoji, and the description stated that you liked to spend quality time on your knees. Holy shit! My hands were shaking as I thought about what this all meant. I knew it had to be you.

My phone vibrated as you sent me a tap, and I could feel my testosterone surging. I tapped you back and my mind was racing. I felt a pang of fear that you might out me, but then I realized that would mean you would have to explain to your wife what you were doing on Grindr yourself.

Another vibration, you had messaged me “Cum downstairs ?,” then your profile went offline and I could hear the floor creak outside our room as you moved tiptoed by. I slid out of bed and threw my robe on before I gave myself the time to think about it this was really happening. My knees were weak as I also tiptoed down the creaky stairs.

As I entered the living area, I could see you were already there, we stood facing each other, maybe eight feet apart. We didn’t dare turn on a light, but the moonlight coming through the windows was enough to see all that we needed to. You gave me a little wave in greeting.

I slowly opened my robe, showing you what you’ve been staring at for years. You put a finger to your lips and then drop to your knees. The next seconds were a blur as I closed the distance between us and you immediately inhaled my cock.

For someone who claims to love sucking cock, you certainly knew what you were doing. Not once did you graze your teeth on me. You sucked me for a few moments to get me fully hard, then pulled my meat out of your mouth and slapped it on your face and I was throbbing.

You gave me a wink and turned your full attention to my cock as you took it as far as you could. Two inches from the base you hit your limit and gagged. But in an impressive display you pressed through the gag and I felt the tip make the turn down your throat and my cock fully disappeared into your mouth. It was slightly uncomfortable but also impossibly sexy at the same time. I couldn’t help but let out a groan as you rocked back and forth on your knees and worked my dick with your throat, while also stroking your own cock furiously.

It was feeling so good my knees were weak and I was having trouble standing. You felt me wobble and stopped. In the dark you pointed to the love seat and I sat down and spread my legs, opening myself fully to you. You crawled into my lap and started throating my meat again.

As I held onto the couch for dear life I noticed you get a sky look on your face, you pushed my legs up higher, then plunged your tongue into my asshole, I couldn’t contain a groan as my brain exploded. You warmed me up with your tongue for a minute before moving your mouth back to my cock. As you did this I could feel your fingers rubbing my asshole, I looked you in the eye and nodded, and the fireworks started again as you penetrated me with your fingers. You quickly found my prostate and started pressing it as you continued to work my cock with your mouth.

So here I was, spread eagle on an Airbnb sofa in a dark cabin while my girlfriend’s brother-in-law deep throats me and massages my prostate. Oh and did I mention both his wife and my girlfriend are sleeping only feet away? We were making enough noise at this point that if either of them were awake they would definitely hear what was going on.

I can’t take it anymore. I grab your head and start fucking your face, moving it up and down on my cock at just the right pace. You let out a gargling moan as my ass clamps down on your hand and my orgasm starts. While this climax might be the biggest of my life, I am also trying with all my might to stay silent during it. I grab your head and push my cock all the way down your throat. I wrap my thighs around your head so you can’t get away. You cough and gag as the first rope hits the back of your throat, but I hold you down and focus all my energy on filling your gullet with all of my cum you have earned. You cough again and I see my cum pour out of the seal between your mouth and my cock. You dutifully take every drop, and then do your best to lick me clean.

I sat on the sofa and tried to form a rational thought while you grabbed a towel and tried to clean up the cushion that was now covered in our combined fluids. It was a lost cause. We flipped it over and I slapped you on the ass as I went upstairs and back to bed. Thinking to myself that this is going to be an interesting holiday vacation.
