I was already soaked when I locked the bedroom door. The house was empty, my parents gone for the weekend, and the only one left was Rex, my big, loyal German Shepherd who had been watching me with those dark eyes all afternoon. I stripped fast, kicking my shorts and panties into the corner, then grabbed the thick, veined dildo from under the mattress. It was the one I always used when I got this filthy itch, the one that stretched me just right.
Rex padded over, tail wagging, nose twitching at the smell of my wet cunt. I dropped to my knees on the rug, spread my thighs wide, and rubbed the fat head of the dildo up and down my slit, coating it in my juice. “Yeah, boy,” I muttered, voice already rough. “Watch me fuck myself first.”
I pushed the dildo in deep with one hard shove, gasping as it filled me. My free hand grabbed Rex’s collar and pulled him closer so his snout was right at my spread pussy. He sniffed hard, then gave a long, hot lick right over my clit and the base of the toy. The rough tongue dragged across my stretched lips and I moaned, pumping the dildo faster.
“That’s it, lick it while I fuck myself.” I worked the toy in and out, wet sounds filling the room, Rex’s tongue lapping at every thrust. My cunt clenched around the silicone, juices running down my ass. I pulled the dildo out, shiny and dripping, and held it to Rex’s mouth. He licked it clean in long strokes, tasting me.
I flipped onto all fours, ass up, and reached back to press the dildo against my hole again. “Come here, boy.” Rex mounted without hesitation, front paws on my back, his own cock already half out of its sheath, red and slick. I guided the dildo into my pussy at the same time he started humping, his hot, dripping cock slapping against my thigh. Every thrust of his hips made the toy slam deeper.
I rocked back, taking the dildo to the hilt while Rex’s cock rubbed and poked, smearing pre-cum on my skin. “Fuck, yeah, use me,” I growled, reaching under to rub my clit. The dildo stretched me wide; Rex’s weight pinned me; his cock kept jabbing closer to my ass. I angled my hips and let the tip of his cock catch on my rim for a second before I shoved the dildo even harder into my cunt.
My orgasm hit fast and dirty. I came around the thick toy, cunt pulsing, while Rex kept thrusting and licking at my neck. I stayed on all fours, panting, the dildo still buried inside me, Rex’s cock now fully hard and dripping against my ass cheek. I reached back, grabbed his cock, and pressed the head right against my stretched pussy lips beside the dildo.
“Want to feel you too, boy?” I pushed the dildo halfway out, making room, then rubbed his slick cock along my open cunt. Rex whined and thrust. The head popped in alongside the toy, stretching me even more. I groaned, low and filthy, and let him fuck me with short, urgent strokes while the dildo stayed inside. His knot swelled against my entrance, hot cum already leaking into me around the silicone.
I came again, harder, pushing back to take as much as I could. Rex’s cock and the dildo together filled me until I was shaking, drooling, and begging out loud for more. When he finally pulled out, thick strings of cum and my own juice spilled down my thighs. I collapsed forward, dildo still inside, Rex licking me clean with long, eager strokes.
I stayed there on the floor, catching my breath, already thinking about round two. The weekend was just starting, and Rex was ready whenever I was.
