To use you again

"Having fun?" he asks

You whimper and look down at your paws as you straighten yourself up.

"Hey, you're not in trouble. I'm not gonna keep you from getting some practice in. Especially when none of you pups are able to cum anyway."

He slides two bowls of dog food into the cage.

"These are for the other two pups. I have your dinner in my office."

Attaching a leash to you, you reenter the office where you signed your freedom away. Adam sits down and takes his cock out again.

"You know what to do. Same thing, no hands. If you're as good as you were earlier, I'll even let you cum."

His cock tastes saltier this time from the sweat of a long day's work, but you suck it anyway. Of all the cocks, his is by far your favorite. You lick it up and down, paying attention to the head in particular. After a minute he holds your head down again and pumps your throat full of cum.

Breathing heavily he lets go and allows you to catch your breath. Then he points to a bowl of dog food next to his desk.

“That one’s yours, but you did good so I’m going to give you your reward first.”

He unlocks your chastity cage and you immediately get hard from hours of pent up frustration. You’re ordered to stand on all fours over the bowl while he milks your cock. His warm, soft hands feel incredible and you cum uncontrollably into the dish. Considering everything that had happened today it was the most intense orgasm you’ve ever had. Even you were surprised by the amount of jizz that coated your dinner.

“Damn. I might have to keep you as my stud, that’s a nice load! Now go on, eat up your dinner while I close up shop for the day.”

You eat your dinner reluctantly at first, but soon realize that the “dog food” tastes better than you expected, and that your cum actually improves the flavor. On top of not having anything to eat for the past several hours, the bowl is empty before you know it.

Adam returns and puts your cock back into a cage, but you notice that it’s a slightly bigger one than last time.

“You won’t be going home with anyone yet, but your dick sucking skills make you deserving of some special treatment. Lots of the other newer pups here can’t suck a dick to save their lives.”

He leads you to a new cage, one that doesn’t have anyone else inside and is closest to the office. There you’re left for the night as Adam finishes closing up and leaves for the night.
