Manny smiled hearing the muffled sounds of the tv in his parents’ room suddenly cease. It was just past 10 and as usual he was waiting for his parents to fall asleep. The 12 year old chocolate lab pup had recently discovered a new fun thing to do before falling asleep and he couldn't wait for his new nightly routine. Staring at the clock on his nightstand he waited 10 extra minutes just to be safe.

With a few minutes gone, Manny gleefully reached down to the waistband of his pajamas and pulled them off along with his undies. Placing his bottoms off to the side, he then pulled the pillow from under his head and slid it between his legs. Curling himself around the pillow he gently began humping his sheath against it. This funny sensation he discovered by accident a few weeks back. He was just trying to pull a blanket loose one night when he realized it felt good to rub himself against the fabric. Having only recently started puberty he still was rather small and unaware of the primal needs a pup like him would soon develop. 

After about a minute he felt his little puppy dick pop out of its sheath. This was accompanied by a shiver of pleasure as the sensitive pink flesh became stimulated by the fabric. Letting himself pant softly, Manny moved a bit faster, poking his dick into the pillow over and over. This feeling was just so great the pup couldn't believe he only found out about it recently. His little puppy cock throbbed and twitched the more he humped. Rolling to one side he pumped his hips harder feeling his sheath roll past his small knot. That feeling was always so wild. He couldn't pull it back that far normally but when he humped the pillow it always pulled back on its own. Being young his sheath was still rather tight which caused a bit of pressure behind his knot. It was like someone had a grip on him and was squeezing HARD. This made his puppy cock even more sensitive too, which only encouraged him to keep going. 
Then came a sudden swell from within him he'd come to expect. Clenching his teeth to avoid howling his whole body shivered, his dick throbbed wildly, and a few drops of clear liquid oozed out of him. He panted as the feeling passed which made him a little more tired but as usual he was still hard and wanted more. 

Crawling out of bed, Manny tossed the pillow on the floor then mounted it. Letting his natural instincts take control, he quickly returned to humping his fluffy mate. A quiet growl accompanied his thrusts. His little knot swelled a bit bigger causing his sheath to squeeze tight again. The open air on his sensitive cock felt amazing paired with the soft folds of his pillowcase. 

“Ah, ah, this feels so gooooood!” He thought, feeling another shivery dry orgasm rush over him. Again a few clear dribbles fell from his tip as his thrusts slowed. Finally stopping he sat on the pillow looking at his throbbing dick. The sight of his own boyhood filled him with a strange happy warmth. Reaching down with both paws, Manny rubbed his sheath and knot gently, enjoying the tingles it gave him. He giggled softly trying to pull it back over his knot, but was unable until the swelling went down. His right paw moved up to his tip where he made little circles with the weird slick liquid that had come out of him. He knew from school what it was, and he wondered when he'd start shooting real semen like a big boy. Not that he minded the clear stuff, but he was expecting something more. 

Sighing he fell forward, then started hugging and humping the pillow for a third time. His thrusts were slower now and he took his time grinding different parts of his cock into the fabric. First his knot, feeling the tightness surrounding the swollen bulb. Then the main shaft building the pleasure once more. Finally circular humpy grinding until he felt the throbbing return and a last shiver pulse through his loins. Unable to shoot even a single drop out now, he knew that was all he could do tonight. 

The weight of his tiredness returning, Manny crawled off of the pillow. He stood at the edge of the bed, and pulled his undies and pajamas back on. They tented outward from his slowly shrinking boyhood. He knew his knot would remain out likely even after falling asleep. By morning his sensitive little puppy cock would be hidden back in its sheath where it belongs. Placing the wet spot on his pillow down against the mattress, Manny crawled under his covers and rested his head. The pup smiled as he tried ignoring the tent in his sheets. It had been a long day, but his nightly routine always made things better. He loved his pillow time and the pleasures it brought him. Curling himself up in his sheets, Manny slowly drifted off to sleep.
