While you're still licking and sucking your pulsing cock your master Sgt. Randy parks his car in an shady alley, checks the surrounding area for people (which are nonexistent) and then leans over his seat, watching you playing with yourself.
He's smiling. Some moments later he get's out of the car and opens the car's backdoor.
You snap out of your licking and lift your head to realize he seems to be calling you out of the car for some moments now.
Panting and tail wagging you stop licking yourself for now, jumping out of the car. Your red cock's still nearly fully emerged and posing proudly.
"You're a good boy," Randy tells you, "and you're a big handsome boy, too."
His words intense your wellbeing and your tails wags faster as you look up to him, panting.
"But I have to show you some more of what you're able to do, my friend," he tells you, kneeling down to meet your gaze.
One of his hands starts to pet your back, which feels great, while the other travels deeper down your body, slowly caressing it's way down your stomach and further onward to your abdomen.
A long, daring second later his searching fingertips reach your cockhead, touching it gently.
Your panting intensifies as his fingers travel ever further, caressing your red cock on it's full lenght. You'd never thought of feeling such things ever before.
"And now on to the big surprise," he whispers, but your pointed ears enhance the noise of the syllables.
Positioning himself at your side and still caressing your back with one hand his grip on your cock grows as he starts to pump it harder.
Your mind fades away completely as sexual tension builds up in your whole body, diminishing everything that mode you human once.
With one further stroke of his hand Randy pulls down on your cock, pushing away the last remaining vestige of your furry sheat. A fist-thick knot appears on the base of your penis and hot white semen starts to pulse out of your cockhead.
Randy's head bends down as fast as he's able to. His mouth envelops your cocktip, as he's drinking all the doggy semen you can deliver, never stopping stroking your penis on it's full lenght.
You pant, but the sexual tension does not ebb away with your first male orgasm, it only seems to make the need for sex worse. It feels like reaching a erotic plateau, while filling up your body with the urge to go even further.
"You'll get your turn," Randy tells you while undressing. He looks around but nobody's around in this shady alley, so no one will endanger the serenity of both of you.
Having shed his clothes randy drops on all four in front of you, lifting his ass up to your muzzle.
Without intention you drink all of his scents, learning as much of him as you'd have while talking to him for hours. It's incredible.
But even more incredible is the urge to mate this man, your master, Sgt. Randy.
Without further considerations you start licking his asshole. It tastes like nothing you could describe with human words, but you can't stop licking it. You tounge caresses his ass-cheeks and even enters his pucker for some moments.
Then you throw your body on his back, grpping his chest with your forelegs, starting to hump your pelvis in his direction.
The tip of your glistening cock seems to miss home for an eternity, but you can't stop trying.
Randy seems to enjoy your training, as his scent intensifies to a state of pure sex lust.
A moment later your cocktip hits home as you're ramming your penis up his ass as deep as you're able to.
Your humping fastens as you take the human male as your bitch.
Time seems to lose meaning while you're humping your master, but your release comes in a thunder of orgasmic shocks which pulse through your doggy body, channeling themselves within your cock and spasming right into Randy's body.
For the eterity of one second he and you are one being. Both of you are complete and in peace with the universe.
It takes a long time for both of you to recover, but as your minds start to operate at normal standarts...
