I couldn't help but laugh when my pup boyfriend showed me the new socks he bought, white with black pawprints at the toes. He was so excited and eager to put them on the next morning. I couldn't help but smile at his enthusiasm as he continued with his day forgetting to wear anything else.
As the day went by I began to notice something about him change. His eyes seemed to grow duller and more vacant, his replies simpler. It was easier to give him orders rather than asking him questions, he'd just dumbly obey. What was the most weird was when he began to smell like wet dog, the socks the worst part. His legs seemed to be a lot hairier than I remembered, dark curls of fuzz spreading up to his ass.
I eventually found him sleeping in the bed on all fours where I got to see the full effects. The hair had continued spreading up his body, curls sprouting from his back. The entire room was saturated in his musk, no doubt in our sheets too. He looked up after noticing me walk in, shaking his newly furry ass toward me, barking.
I couldn't pass up this opportunity. I felt my body heat up as I approached him, my need for him growing with each step. I saddled his rear, slowly pushing into his furry ass, his head bowing as he took my whole cock. A low growl came from his throat that slowly turned to moans as I began pulsing, a shiver spreading through his body with each thrust into him. He began to howl, his body tensing around my cock as I filled him completely. I could feel his instincts taking over, pushing back, becoming a dumb good boy as I fucked him.
I felt myself reach orgasm, my body shuddering as I filled him with my cum. He howled for a moment before collapsing into bed, his body spent. His head lolled to the side once I pulled out, his body laying in a horny daze. I couldn't help but feel satisfied, happy with the changes. I knew this pup would always be waiting for me, happy to take my bone whenever I felt like giving it.
