I’ve never been ashamed of what happened that weekend — it was the most exciting night of my life and completely changed me for the better. Two years ago, at 25, I was still stuck in a boring routine when the neighbors asked me to house-sit while they were out of town. Their 21-year-old daughter Tanya was home from college, and they had two massive boxers — Tower and Frasier — that needed looking after. Their son Marcus was also 21. I happily accepted.
That Friday night, I was relaxing on the big leather couch in just a loose sweatshirt and panties, flipping through TV channels, when I heard the front door open. Tanya and Marcus stumbled in together, laughing and clearly buzzed from a college party. They were dressed up — Tanya in a tight little party dress that hugged her curves, Marcus in a button-up shirt with the sleeves rolled up. They both looked hot and full of energy.
“Oh hey, Sue!” Tanya giggled, kicking off her heels. “You’re still here? We thought you might have gone home already.”
Marcus grinned as his eyes roamed over me on the couch. “Looks like we got back just in time for the real party.”
I smiled, feeling a rush of excitement instead of embarrassment. Tower and Frasier had been prowling around the house all evening, and I’d already been teasing myself with the idea of playing with them. The dogs immediately came over to greet the siblings, but Tower quickly circled back to me, shoving his big head between my thighs.
I didn’t stop him. In fact, I spread my legs wider, letting his hot tongue lap at the crotch of my soaked panties right there in front of Tanya and Marcus.
“Fuck… Sue,” Marcus breathed, eyes wide. Tanya bit her lip, watching with growing interest.
“He’s been like this all night,” I said breathlessly, pulling my panties aside so Tower’s rough tongue could drag directly over my bare, dripping pussy. “I’ve been dying for this.”
Tanya laughed softly, clearly turned on. “Damn, Sue… you’re such a dirty girl. Don’t let us stop you.”
Tower didn’t need any more invitation. The huge muscular boxer mounted me on the couch, his heavy paws on either side of my hips. I reached back eagerly, guiding his thick red 10-inch cock to my entrance. When he thrust forward, burying half his length inside me, I moaned loudly in pure pleasure.
“Yes, Tower! Fuck me hard!”
The dog started pounding me with fast, powerful strokes. His cock felt amazing — so hot, thick, and deep. I pushed back against him, meeting every thrust like a bitch in heat. Marcus and Tanya watched, both of them getting visibly aroused. Marcus was already rubbing the bulge in his pants, while Tanya slipped a hand under her short dress.
When Tower’s massive knot began to swell, I begged for it. “Give me the knot, boy! Lock it inside me!” The huge softball-sized bulb pushed past my entrance and inflated deep in my cunt, stretching me perfectly. I came hard, shaking and squirting around his cock as hot jets of dog cum flooded my womb.
“Oh god, he’s breeding me!” I cried out happily.
Tower turned, and we ended up ass-to-ass, tied together. I loved the full, stretched feeling. Marcus stepped closer, filming with his phone while Tanya cheered me on. “Look at you taking that big knot like a pro,” she said, touching herself.
After the knot deflated and slipped out with a wet gush, thick dog cum poured down my thighs. I scooped some up and licked it while looking at the siblings. Frasier was already hard and ready. I got on all fours eagerly.
“Your turn, Frasier. Come fuck me too.”
The second massive boxer mounted me immediately. I took him just as enthusiastically, moaning and pushing back while Marcus finally pulled out his cock and fed it to me. I sucked him greedily, swirling my tongue around his shaft. Tanya stripped off her party dress and sat on the couch in front of me, spreading her legs so I could lick her pussy while Frasier knotted me.
The night turned into an incredible bestiality orgy. The dogs took turns knotting me over and over — on the couch, on the floor, even bent over the kitchen island while Tanya and Marcus watched and joined in. I sucked both dogs clean after each breeding, loving the musky taste of their cum mixed with my juices. Marcus fucked me between rounds, using the dogs’ cum as lube, while Tanya sat on my face and made me eat her out.
We moved from room to room. At one point they took me out to the backyard where I got knotted by both dogs under the stars while the siblings took turns using my mouth. I was in absolute bliss, begging for more cum, more knots, more everything.
By the time the sun started to rise, I was a happy, exhausted, cum-soaked mess — leaking dog cum from my well-used pussy, covered in it, and completely satisfied. Tanya and Marcus cuddled up with me on the couch, the dogs resting nearby.
“Best house sitter ever,” Marcus said with a grin.
Tanya kissed me softly. “You’re definitely coming back next weekend… and every weekend after that.”
From that night on, I became the family’s favorite house sitter. Whenever they had a party or went out, I was there — eager to take care of Tower and Frasier… and anyone else who wanted to join. My boring life was gone forever. Now I live for those big, knotted dog cocks and the fun we all have together.
