“Open up Mutt” He growled as he stood strong and crossed armed above me. He stared down at me with those big black piercing eyes. His cock stood rigid and attent against his taut gut as a striking contrast to his white polar fur, a single drop of pre cum crowing the pillar of male girth. Scared and inexperienced I opened my mouth wide and he grabbed me by my head.
“Good boy” he said as his fingers pressed to my skull, his thumb at my hair line as his palm was flat against my forehead.  He grabbed hold of his cock at the base and angled it so its press against my tongue as it covered my teeth.  His cock was hot against my tongue and was an odd appealing taste of his salty pre and musky taste.  I opened my mouth wide and curled my top lip over my teeth as he guided his cock into my mouth, my jaw straining to fit around his cock. I expected him to pull back or maybe stop when he hit the back of my throat and made me gag but he didn’t, he just kept going. I tried pull my head back as his cock stretched my throat but only succeed in making him mad.
He let out a deep angry growl as he yanked my head flush against his groin, smashing my glasses into my face and hilting himself down my throat and showing that he had all the control. His musk was a heavy mix of sex and sweat. I grabbed hold of his thick legs and tried to tell him to stop, digging my fingers into meaty thighs. He knew and didn’t care. 
I looked up pleading, tears forming at the side of my eyes as my lungs burned for air. He gave me a mean look like I was causing him the problem and pulled all the way out. I cock slick with my spit standing up straight and shining like a knight.
I choked and sputtered as my body tried to get fresh air inside of it. His fingers flicked at my ears playfully as I tried to gain back my composer. I whipped the mix of slobber and pre cum from my face with my forearms and cleaned my eyes before I opened again, putting my hands back on the floor after I was done.
He wasn’t gentle or slow as he started again and doubted either of us cared, he wanted to use me and I wanted him to use me.  “Good boy” he cooed at me like I was a pet and brushed my hair back with his thumb as he bottomed out in me again. I closed my eyes and didn’t try to stop him as he held me for a little, enjoying the feeling of my throat stretching and flexing softly against his cock. He only pulled his cock half way out when I stopped gagging. It was just enough for me to catch some breath but he didn’t let it last too long before sinking back into my throat and pressing my nose into his pubes.
His balls gave a soft tap against my chin as he started to meet my mouth with strong fluid thrusts, getting them wet from the spit on my chin. After a while I stopped gagging and learned to breathe through my nose, which helped but didn’t do much when he was all the way in my throat.
He growled deep and pinched my ear as his cock started to pulse in my throat, warning me he was about to come. With both hands he pulled me to his groin, bottomed out in my throat and shot his load down my throat. His balls pulling tight up against my chin .His cock throbbed in big long spurts as he shot gobs of his white stuff down my gullet into my stomach. Amazingly he wasn’t done he kept going like nothing had changed. I whimpered around his cock think about going a second time as my mouth was already sore and tired.
Compared to the first time he was a saint as he took my throat for a second round, that or I just got use to it. My face was a mess of spit, pre cum and cum by the time he got into his stride again.
“You’re pretty good kid” he complimented me and oddly I was flattered and started to blush. It took him a lot less time than the first time for him to come a second time. He threw his head back and pulled his cock just enough so that he filled my mouth with his come as he came, the pungent salty cream filling my mouth.  I was surprised and overwhelmed by the amount of cum he could put out as my mouth was over filled with the stuff and it showed as the stuff started to leak out the sides of my mouth. I tried to swallow all I could but was it didn’t work as it spilled from my nose and mouth. It stun to high hell when it hit my nose but I was just glad it was over as he started to soften as he pulled out.
There were few words exchanged as he stuffed his soft cock back into his jeans and left me kneeling on the rest room floor. He promised we would do this again when he got back from road and oddly enough I looked forward to it.
