John's standing over me pushing my face onto the floor with his foot as he opened his nearby drawer and retrieved a collar, and connected to it a long chain. He removed his foot from my head and said "ok pup, sit". I stayed on my knees and lifted my head up. He put the collar around my neck and tightened it as far as he could. Reducing blood flow to my head, but increasing my horniness in turn.
"Look at you, pathetic, just came and already hard again. Stay."
He tied me to the bed post and left the room, leaving the door wide open. His mom was away working nights, but his dad was due back any second. The exposure felt intoxicating, I wanted to be found looking like a bitch in heat. He returned and looked at me, "good boy you didn't move an inch, I have another present for you.". I tilted my head, un sure of what it is he reveals it from behind his back. "Yeah my parents are into some kinky shit, probably where I get it from." He holds a monster of a butt plug, probably 10 inches around, and lube, thankfully, in the other hand. "This is going in you, so get your face down, ass up fag." I obeyed and I felt the cold chill of lube slide down my crack, as he starts teasing my hole with his fingers my hips instinctively gyrate back, giving him the room he probably was going to need. He stops, lubing up the plug he starts pressing it into me. It fills my ass halfway in, already feeling stretched to my limits. He doesn't care he continues putting pressure making me start to moan again. It feels like I'm going to break then, pop, it's in I feel fuller than ever before and I'm leaking cum, that's pooling below me again. "Pup, up... now!" I'm forced up by the cain connected to my collar. "Get dressed again I'm taking you for a walk." We both get dressed, for me every move I have to stifle a moan. He's dressed and before I can put my skinny jeans back on he stops me. "Let's do this quick, before you get a rager, fag." He puts my balls through a ring and next shimmies and forces my dick through it. I'm already getting hard, but then he puts the cage on, and locks it in place. "Now your really a fag, with this clit." My dick pressed against it, I've always wanted to do chastity but I was too weak, now I'm going to have to get used to it fast I continued getting dressed and he lead me out the door to his car. My new clit was throbbing and leaking as he took me somewhere. Every bump I moaned so close to cumming thanks to the beast of a plug in my ass. We stopped at a National park riddled with trails, the parking lot was empty. We got out, he handed me knee pads and thick gloves, "take off you clothes dog, dogs are naked on all fours." Nervously I stripped and put on the pads and gloves, and got on all fours. He grabbed the leash and off we went. Struggling to keep up I stopped, I had to pee, I lifted my leg and went. I heard a zip and quickly felt a stream of piss hit my back. "Just marking our territories right?" I turned and started gulping down what I could. "What are you a urnal more than a dog now?" After he finished we walked farther me nude, and him with his dick out of his fly. He stopped at a stump and patted the top, "up boy" I put my arms on it and he grabbed the plug and pulled. The sound was loud, and wet, leaving my hole gaping more then ever. "Damn your loose now." He shoved his dick in replacing the plug and humped me relentlessly. My clit leaking onto his hand feeding me it when it was full. Then a loud "holy shit!" Was said and I looked at it to find a guy in shock. Instead of stopping we still were going, harder if anything. With my low air supply and between my moans I seen, something throb in his shorts. Lifting them up to revile his raging dick he stands in front of me and shoved it into my mouth. In shock of what happened all I could do was open up and allow him access to my throat. My eyes watering as my ass and throat get filled, first in my ass for the second time he fills me, then the guy in my throat pulses and fills my stomach, pulling out and shooting his last rope across my face. The man puts his dick away, "thanks for the slut."
"No problem he's a good pupper, isn't that right?"
I lift my head, face still covered in cum, and look at them, "arf!" Wagging my ass, panting with my tongue sticking out.
"See he loved it, now come on let me re plug ya."
I throw my hips back to feel the familiar plug work is way back in. With a pop it securely is in place.
He grabs my leash and we start walking back to the car. When we arrive he opens the back door and goes, "up boy let's get going."
I get up in the back and lay down on the seats and we go.
