Mastiff On The Sly

(c) 2015 by zooplug

I was at a camp site in a nature area when the owners large Mastiff came to check the territory. He stopped at the shrubs on the edge of the camp site and cocked his leg to leave his mark. His cock looked massive in its sheath and a very small bit of pink tip was showing as he sprayed the shrub.

I was sitting next to my tent watching him and wondering just how big that cock was. He was a very large specimen even by Mastiff standards. While I dwelt on this thought, Jake (the dog’s name) came up to me and licked my hand. I petted him stroking down his back and I couldn’t resist rubbing his side and then slowly sliding my hand down till I wrapped my fingers around his huge cock inside the sheath. Jake immediately straightened his back and moved his leg out of the way to give me easier access. He obviously enjoyed it when I touched his cock.

I stroked his sheath slowly while looking around to make sure that nobody was watching. Jake’s cock grew inside the sheath and the now very red tip had emerged from the sheath by 2 cm. It was bright red and some pre cum started spraying out. I gently massaged the tip and rubbed the cum over the sheath. I could feel his cock was rock hard and the knot was BIG and hard. I tried to push the sheath back but his cock was too big and he showed discomfort so I stopped.

When I took my hand off his cock Jake sat down and licked the protruding tip and I watched as his cock started to shrink. I wanted to feel more of that cock but there were too many people around. I had to make another plan if I wanted more of that beautiful cock. Jake then jumped up and trotted off to mark the rest of his territory.

A while later I spotted Jake wondering off towards the river and I quickly followed. I caught up with Jake at a secluded spot on the river bank and went through the greeting ritual rubbing his ears and back. As soon as I slid my hand down his side Jake stiffened waiting for me to touch his cock. I didn’t disappoint him and gently stroked his cock in the sheath. It started growing immediately so I stopped. Jake bounced around me excitedly and then jumped up against me trying to mount me. This was so exciting and I quickly looked for a spot that may be well hidden from prying eyes. All the time I had to fend off Jake without scaring him away.

I moved quickly into the shrubs and undid my shorts. My cock was leaking pre-cum and it was obvious that Jake could smell my sex. Jake’s snout was right at the zipper as I pulled it down waiting for my cock to appear. I pulled out my cock and allowed Jake to sniff the tip of my cock before he gave it a tentative lick. This felt so good and I hurriedly dropped my shorts and jocks exposing my ass. I went down on hands & knees and stuck my ass in Jake’s face. He sniffed at my ass and then started licking slowly.

I shivered in anticipation as his wet tongue made contact with my ass. I slapped my ass and invited Jake to jump up but he didn’t understand what I wanted. I reached back and pulled his front legs onto my back and still he didn’t understand what I wanted. I pulled him forward till I could feel his sheath touching my butt and his weight was on my back. I reached back between my legs and wanked his sheath a few times.

Now Jake knew what was required and he started humping. His hard tip hit my left buttock, the the right buttock as I moved my hips to position myself to take his cock. On the third hump he hit the target and I felt the tip of his cock slide into my waiting ass. As soon as Jake felt that the tip was in his humping became forceful as he drove his cock into me. It was an amazing feeling and hi cock quickly grew. The girth expanded stretching my ring deliciously. Jake was pounding me hard and his claws were scratching my sides as he gripped harder to force hi growing knot into my tight ass.

I got nervous thinking that I am doomed if he manages to force that enormous knot up my ass. I reached back and placed my fingers in front of Jakes knot so that I could enjoy the pounding and keep his knot out. His knot quickly grew to maximum size filling my whole hand and Jake slowed his humping till he just laid on my back panting in my ears. I held his knot and pulled it tight against my ass while I enjoyed the delicious sensation of the massive cock throbbing in my ass while Jake pumped his seed into me. When he was done cumming he slid off my back and I released his knot so he could pull hus ten inch cock out of me with a slurping sound. What an amazing sensation! I felt his come leak out of my ass and I had to squat to allow the excess cum to exit before I could pull on my jocks and shorts. Jake was off to one side licking his cock that wss slowly shrinking. As soon as his cock retreated into the sheath it was safe for us to emerge from our hiding place to wander along the river. All the while I am aware of the delicious squelching wetness around my ass. AMAZING!
