[M4F] Niece's IG Wrecks My Marriage.

NSFW

​

When my sister reached out to me and asked if you could live with me while you attend school at the local university, I happily said yes to the opportunity of having my lovely niece staying with me for a while. She assured me it would only be for a semester and that you would be on your best behavior and after a few months you would find your own place once you got settled. My wife also happily agreed, thinking it would be fun to have you living with us and bringing your youthful energy into our home. All of that excitement quickly turned to apprehension when she found your Instagram. 1000's of thirst traps, all perfectly curated to showcase how fuckable and hot you were. She scrolled through every single one of them before bringing them to my attention, as if seeing your gorgeous, young body would dissuade me from having you with us.

I tried assuring her that it's just what girls your age are into until she set her phone down on the kitchen counter and I saw for myself. My cock fucking jumped at the sight of your latest post. Your perfect, plump ass filling up the screen with your manicured nails digging into the soft cheekmeat to pull it apart. Not even noticing the panties you're wearing as they're absolutely devoured by your thick ass, barely able to cover your puffy pussy lips with the caption "It's pink like bubblegum πŸ’‹πŸ’¦" Forcing me to act naive when she asked me what that meant.

I assured her everything would be fine before I went up to our bathroom, created an Instagram account, and stroked my meaty dick until my eyes rolled back as I imagined blowing a massive load deep into your younger, better pussy. My balls still ached as I scrolled deeper into your collection of thirst traps until I settled on one of you wearing just a towel after a shower. What made me pause on this one in particular was the caption "I hate condoms 😑" with your young body stretching the towel around your wide hips, accentuating how breedable you were and hinting at your desire for it. Once again imagining your homewrecking pussy coiled around me as I unload into you and give you the baby that my wife has wanted for years. Feeling massive ropes of nut busting out of my swollen head as I stare into your eyes on my phone screen until I've busted enough nut to knock you up 100 times over.

The next few days were very tense between my wife and I. You weren't even here yet, and my wife was already a nervous wreck about you being around her husband. I could sense she desperately wanted to tell me that she wasn't comfortable with you living with us, but she just couldn't work up the courage to actually say it. She was always rather timid, an attribute you clearly didn't have, but she knew your perfect, tempting frame could bring trouble to our marriage. Yet she still made up your room right down the hall from ours, our rooms sharing a wall, her attempt at keeping an eye on you, instead it will just end up as another surface to fuck you against when I set my marriage aside to dick you down.

I knew what was likely in store once you moved in and I knew the potential consequences of tossing my marriage aside to enjoy some prime, pink pussy. None of it was enough to stop me from allowing it to happen. You weren't even hear yet and I already felt like a young man who was letting his hair-trigger cock do all the thinking for him.

The day finally came, and you were standing on our front step when I pulled the door open with my wife standing beside me. Your little dress only served to accentuate the stunning, marriage destroying body that stood in front of me. Our eyes met, and in that moment I knew my marriage was utterly fucked. You had everything my wife didn't, and all three of us knew it immediately.

"It's so good to see you!" Putting on a facade of a caring, excited uncle, when in reality all I was thinking about was flooding your tight, little cunt with loads that should go to my wife.

"Come here, it's been so long!" My strong arms snake around your body and pull you against me as my wife stands back, watching with jealousy at our simple, innocent gesture. Your scent causes my already growing bulge to swell against your stomach, your fertile, ovulating pussy sending out pheromones that scream 'BREED ME'.

Thanks for reading! I need a naughty, little homewrecker to fulfill this role. Someone who can play a sweet, charming facade for my wife while also being a wicked, marriage destroying slut. Using your charisma to convince my wife that your harmless all while planning on nuking my happy marriage with your perfect body and fertile pussy.

I'm James, I stand at 6'2" tall and around 195lbs, depends on how hard I've been working in the gym. Short dark brown hair sits thick on top of my head, perfect for running your fingers through as I'm devouring your pussy. I've got sharp Blue eyes that border on Green if the sun hits them just right. I've worked extremely hard over the years to have a muscular frame with a wide back and a defined, thick chest that you can prop yourself up on when bouncing yourself on top of me. My arms have a few prominent veins running down the length of them along my thick forearms and large, calloused hands . My skin has a nice Olive tone from my Italian Dad and is accompanied by an even tan from working outside so often. Anything else you want to know about my looks, feel free to ask!
