Chapter Nine

It took another thirty minutes before Jingo's knot shrunk enough for him to slip out of her stretched pussy with a squishy loud popping sound. When that happened Mac's ass fell the few inches to the floor with a thump.

"Oh shit" Mac exclaimed.

When she looked down at her groin she could see a steady flow of doggy cum pouring out of her cunt, puddling to the floor under her.

"Damn Jingo," she complained. "Now I'll have to wash the floor."

But before she could even move, Jingo lowered his head and began lapping up the rich sexual mixture of his cum and hers from the floor.

Mac just watched him excitedly as she knew that he was tasting her all over again. She reached over and scratched his head as he licked the floor. Then her gaze followed his body to his rear and smiled.

Though shrunken slightly, his cock was still impressive looking. At least eight inches hung low under his belly. Mac could clearly see the clear lubrication coating it that came from her own pussy only moments ago.

"You're really a good boy tonight Jingo," she cuddled next to him. "I should do something special for you as a reward. What do you think?"

The dog simply raised his head a moment and licked her across the lips, leaving a trail of doggy jism and her own cummy residue.

Mac didn't even give that a second thought. She ran her tongue across her lips to gather the stingy offering that Jingo had left for her and tasted her dog's seed for the first time.

She found the cum a bit saltier than the ram's but not much different. This made up her mind on what she was thinking just a moment before. She would give Jingo a blowjob as a reward.

Leaving Jingo to his cum treat on the floor, Mac slid over next to his hindlegs and lowered her face under his furry belly. Reaching up carefully, she delicately touched Jingo's cock and grasped it. It felt slimy and slick in her hands. The mixture of his cum and hers over it made his cock sticky, yet slick at the same time.

Jingo only paused for a moment from his licking the floor clean to gaze at his mistress. Once he was satisfied that she wasn't trying to hurt his penis he lowered his head and resumed his licking.

Mac made the bold move and ducked her head under his belly and guided his semi-hard cock to her lips. She parted them in an irresistible 'O' and slipped Jingo's cockhead into her mouth, sucking on it immediately.

The dog raised his head again approvingly before returning to the salty juices on the floor before him.

Mac sucked in the first six inches of his cock down her throat and busily worked on getting the remainder down there as quickly as possible. The easiest way she knew how to accomplish that was to give the dog a blowjob and work him down one inch at a time.

Once her plan was set in motion, she began bobbing her head to and fro on Jingo's cock, driving it a bit deeper into her gulping throat with each stroke.

She was quickly rewarded for her efforts when she could feel his cock surging back to life. She could feel it stiffening and elongating even as she sucked on him. Whit this sign of encouragement, she doubled her efforts to deepthroat Jingo.

Feeling his cock getting aroused once more, Jingo began humping his ass into Colonel MacKenzie's mouth. He seemed just as eager to fuck her throat as she was to drink down his jism.

As Mac continued working her mouth on his raging hardon, she stretched open her legs with the intention of playing with herself. But Jingo, being ever so resourceful, feat her to it. he buried his snout into her outstretched pussy and began licking her feverishly.

"Mmmmmmmmmh!" Mac could only moan through her cock stuffed mouth.

She recognized that they were doing a 69, but not in the normal position. Wishing to get more comfortable so that she could enjoy this all the more, Mac scooted under Jingo's body, sliding her pussy directly under his head. In this position she found that she had to stretch out her neck to keep sucking his dick, but she didn't mind that at all.

Realizing that what they were doing was quite unnatural for a dog, Mac began wondering how he had learned all of this so fast.

'It couldn't be natural for a dog, could it?' She asked herself.

Her keen lawyer mind began trying to figure out where Jingo could have learned to fuck a women so well. She knew that he was a stray when he was recruited into drug enforcement. Could it be that his previous owner had taught him.

'That must be it,' she concluded. 'How else could this happen.'

Now that her mind was satisfied with her conclusion, she returned to eagerly suck him. She wanted to taste his cum as it shot out of his piss slit. From what she felt in her pussy when he came before, she hoped that the shooting jism would be just as powerful a stream of cum as she had imagined it to be.

Jingo kept humping her face furiously, driving his now fully erect cock deep down Sarah's throat. She had to work hard to swallow it all.

All the while, the dog kept on licking and nibbling at her cunt and clit.

"Arrgggghhh!" Mac finally groaned as she came yet once again for her dog.

Just then Jingo began shooting his cum into her stomach. His cock was deeply imbedded down her throat and Mac had to push against his hindlegs to pull his cock far enough out so that she could get a taste of his cum on her tongue.

Jingo had shot two powerful spurts right in her throat before Mac finally managed to lodge his cock in her mouth. Now she could use her tongue on him. Her tastebuds got their first taste of what doggy jism really tasted like right from the source. Mac couldn't get enough of it. She kept on sucking even after the dog's cum was only a trickle.

Once they were both satisfied, Jingo walked over her prone body and went over to a corner and licked his cock clean.

Mac just watched him doing that for a moment, before getting the energy to get up herself. She wobbled her way to her bathroom and ran a bath for herself. She needed to clean off her body of the cum and sweat.

After that relaxing bath she went straight to bed, not bothering putting anything over herself. For the first time since she was a teenager she slept in the nude.
