A few weeks later...

The door to your house opens.

You sniff the scent of your owner even before she stepped through the door. Barking, you rush towards here. Finally Kin is home! Time to play! While you run and jump towards her, you marvel at your muscles and your strength. You have never felt so agile and so powerful for your whole life. Your body is fit. You can run on all fours for hours through the garden or the forest, and you can, of course, pleasure Kin for hours as well. The thought makes you grin. You feel your cock throbbing. It is, of course, fully erect. It's always fully erect. There's an insatiable sexual hunger that stays with you the whole day and the whole night.

You jump into Kin, as she closes the door, laughing and giggling at your sight.

"Jon! Let me at least get rid of my coat first, you crazy puppy!"

You sniff and bark and rub your head against her legs. Her scent is overwhelmingly arousing, sweet and spicy and musky at the same time. You rub your nose against her crotch. She giggles. "Oh Jon, you horny stud dog. Again? You just humped me this morning." Then she looks at your hard and erect cock poking out from between your legs and giggles more. "Oh my, I see, I see."

She walks into the living room, and you follow, panting.

"I really should get you a playmate, Jon", she muses. "Maybe one of the new puppies from the special section. Would you like that, hm?"

You lick her hand, while she sits on the sofa and stretches her arms and legs.

"Then the two of you could mate, and I don't have you jumping at me basically 24 hours a day. It does get a tiny bit exhausting, you know, Jon?"

Then Kin laughs again, opens her trousers and pulls them down.

"Ah, well, on the other hand...", she smirks, and opens her legs. "Come here, Jon! Come! Tongue!"

You know exactly what your owner wants, and you bury your head deep in her crotch, licking her dutifully with your long and well trained tongue. Kin sighs and quickly starts to moan, while she sinks deeper into the couch.

"Yes - there! Mmmmmmh", she moans and her hand wanders through your hair. "Good stud dog!"

You bark happily and continue your efforts. Your cock is still throbbing like crazy, but you try to ignore it. You are well trained and can follow an order.

"Alright, Jon, you convinced me. Come on, climb on top and fuck me!", Kin says, smiling.

You don't need to be told twice, and you are on the couch and on top of your owner in a heartbeat. "My, my, my strong puppy", Kin teases you, and then her eyes go wide for a moment, as you push inside her.

"That's good, Jon, mmmmh", she mumbles. "Such a big cock."

You happily start fucking her, following your animalistic instincts. Soon, both of your are moaning and groaning and humping on the couch.

"Ohmygod, I'm cumming Jon!", Kin moans, just before you shoot your load into her.

Afterwards, she cuddles you, happily.

"See, Jon? I told you - I make you the happiest dog in the world. It was a good decision, after all."

You don't know what Kin is talking about, but if she's happy - so are you.
