Playing with my pet

My dog Roy and me have some fun together.

My first experience with zoo was in high school. The family dog, a female black lab, was in the room after I finished jerking off and ate the cum off my stomach and thighs. At first I tried to stop her but then her tongue grazed my dick and the rest was history. I ended up fucking her a few times but after I moved out I decided to get more adventurous. I adopted some German shepherd hybrid names Roy. Whatever was in his dna made him huge, about 130lbs with a dick to match. I started out with what I was used to, had him clean up my cum, lick my face while I jerked off. Eventually I decided to explore Roy. I did some research watching zoo videos and saw someone use a chair so their dog could mount them properly so I went with that approach. I set up a chair in my room, had towels under it, and brought Roy over. I knelt down and started kissing him, lots of rubs to get him excited. I started to rub his dick to get it ready. Once it was out I layed down on the chair so I was facing away from him. He was definitely ready cause he started eating me out, his long rough tongue felt so good, every lick made my brain go numb. Anytime he reached my balls a shockwave went through me. At long last he finally started to mount me, his strong frame pinning me down. I felt him start to search for my opening, humping frantically. I started to reach back when he suddenly shoved it in me. I had played with my ass before, even letting an ex peg me. But this was different. His warm cock filled me up completely, I felt every inch as he pushed around my guts. I forgot to put something on his paws so I felt his claws scratch my back. I didn’t care though, I wanted him to use me. I was screaming like crazy, which must have startled him cause i felt his mouth clamp down on my neck. Like he was making his bitch stop complaining. I bit my lip as he pounded me, his drool dripping onto me. I was lost in the pleasure when I started to feel something pressing against me. Mistake number two, I forgot to block his knot. I tried to reach back there but his claws dug into me again as he forced me back down. I screamed when he shoved his massive knot into me. His cum pouring out, the burning sensation in me was crazy. My dick was pouring out cum from my multiple prostate orgasms. I was like that for at least 15 minutes. His hot breath on my neck while his weight kept me in place. His occasional licks felt like he was comforting me. He started pulling out of me and I felt like my ass was going inside out. I bit the chair in pain as he finally took out his knot. His cum poured out of my wide opening. I managed to roll over onto the floor and just stared at the ceiling. After a bit Roy’s training kicked in at the smell of cum and he started lapping up my overstimulating dick. It felt like lightning bolts. I couldn’t push him away, he made me cum probably about 3 times before I was completely spent. Once I was forcibly cleaned up he layed down on my chest. I wonder what I’ll try next
