Emily is right there

Your cock springs free of its cage, getting rock hard in moments. Emily tries to back up and out of the way but you’re too quick, tackling and landing on top of her.

“Wait wait wait!” She says, but she is not your master. Only one person in this house can command you to stop, and he isn’t saying anything.

Your cock buries itself deep inside her as she cries out, but once you’re inside she doesn’t fight back. Instead looking over your shoulder at the man who commands you both. It’s clear from her face that she’s humiliated by the situation, but also that the humiliation only increases her arousal.

Her pussy is smooth and warm, and tighter than any you’ve ever fucked. You think about how long it’s been since you had fucked or been fucked by anyone but Master who wasn’t a pup. Being puppy slaves like yourself, the animalistic and non-verbal sexual encounters had been less of a shared experience and more closely compared to two people masturbating themselves by using each other. Or more often than not, one pup using another pup’s body to masturbate. You’d seen it, and been a part of it several times both on the giving and receiving end in your month at the kennel. This on the other hand was different. Emily, Alec, and anyone else but Master were (for the night) willing participants in Master’s game of rewarding you.

You hump her to completion, filling her with your cum as her moans almost reach a climax, but stop short of her own orgasm. She doesn’t look you in the eyes, and you guess that her self-denial was intentional. Some of your cum spills as you pull out, and you go to lick it when Master says

“Not tonight Ace. Tonight Emily is responsible for licking up every drop that drips out of her. As Is anyone else you rut. Understand Emily?”

“Yes sir.” She says, already going to lick it off of the tile.

“And Emily,” Master says in the tone of someone tired of reminding their submissive of a mistake they’ve made “remember what you say to anyone who uses you?”

“But it’s a-“

“A pup, yes, but just for tonight it is above everyone but me in the hierarchy, so you will do what you are trained to do.”

“Yes Master” she says, sighing like she was about to do something she didn’t want to “thank you for using this slut Sir. My holes are yours to fill.”

“Good girl.” Master said. “I’ll punish you for your hesitation later.”

You get off of her, and notice that despite having just orgasmed, you were still horny and your cock was still hard.
